Abstract: A permanent magnet applies first sliding resistance in-between a holding arm and a guide rail. A carriage is provided with an electromagnet for magnetically applying second sliding resistance in-between the holding arm and the carriage. Although the holding arm persists in moving through inertia when the carriage stops movement, a sliding resistance that is the sum of the first sliding resistance and the second sliding resistance acts on the holding arm, and it is possible to promptly stop. Since the second sliding resistance does not act when the carriage brings the holding member, it is possible to reduce a load. When the carriage starts bringing the holding arm, a difference between the first sliding resistance and the second sliding resistance becomes the sliding resistance, and it is possible to decrease sliding resistance that acts when bringing is started, and reduce occurrence of an impact and a noise.

Abstract: A weft knitting machine having a movable sinker capable of securing a large space at a needle bed near a knitting fabric knitting area and making a pause in the state of stopping action on the knitting fabric knitting area. A sinker operating cam mechanism (10) installed in a carriage acts on the butt (12c) of a sinker jack (12) to move the sinker jack (12) backward from a mouth part (2) so that the acting part (8c) of the movable sinker (8) can retract from the mouth part (2). The sinker jack (12) is locked to a moved back position by a locking mechanism (16). Since a wire (17) passed through a needle plate (5) is utilized to lock the sinker jack (12) in the locking mechanism (16), the locking mechanism (16) can be reduced in size. To lock the sinker jack (12) to the wire (17), the sinker jack (12) comprises a projection (12f).

Abstract: A distance can be measured with high resolution. A frequency controller (7) controls a voltage control oscillator (2) so as to change a signal source frequency f in a range containing two center frequencies f1 and f2 and transmits it as a traveling wave from an antenna (4) to a target (5). A reflected wave reflected by the target (5) and the traveling wave interfere each other and form a standing wave. A power detector (6) detects power corresponding to the amplitude of the standing wave and performs Fourier transform based on the two center frequencies f1 and f2 in Fourier transform means (11, 12), respectively, thereby calculating radar image functions P1(x), P2(x). The distance d to the target (5) satisfies the conditions that the phase difference of the two radar image functions zero-crosses and the amplitude of the radar image functions becomes maximum. The zero cross point of the phase difference is a zero cross point of a linear function and can be identified with high resolution.

Abstract: An object of the invention is to control the yarn length as appropriate in a tubular knitted fabric including a drop loop, regardless of the presence of crossover. For front and back needle beds, ones of those indicated by capitals ABC . . . among odd-numbered or even-numbered ones are allocated to a front portion thereof and the other portions indicated by lower cases abc . . . are allocated to a back portion thereof. At knitting needles ABC . . . which actually form stitch loops perform knitting operation, and knitting needles abc . . . between the knitting needles ABC perform hooking operation. A hung stitch is shook off, and the knitting yarn used for the hanging is absorbed in stitch loops at the knitting needles ABC . . . at both ends as shown in dotted lines. As shown in (b) by solid lines, the loop lengths of back stitches are shortened and the lengths of the knitting yarn at crossing portions are absorbed by the stitch loops of the back stitches.

Abstract: An object of the invention is to be provide a yarn feeding apparatus of a flat knitting machine capable of accurately predicting a required amount of a knitting yarn and knitting a fabric while supplying knitting yarn necessary for knitting. The knitting yarn is fed out based on an idea shown in a solid line in consideration of a yarn speed corresponding to the requirement for knitting yarn produced according to the movement of a yarn feeding member as shown by chain lines in FIG. 6(b). A knitting yarn is stored on a buffer rod at a start of knitting because the speed of a motor such as a servo motor for feeding a knitting yarn lags behind the yarn speed. A knitting yarn that runs short at the time of deceleration at an end of knitting is also fed out in advance.

Abstract: A method for realizing embroidery simulation which can be used as an alternative sample to an actual object. A shade is added to a stitch not to brighten the center of the stitch and to darken the opposite ends thereof as shown at (a) but to brighten a stitch A close to a light source most and to darken a stitch B remote from the light source most as shown at (b). Assuming that the light source is not located on a two-dimensional plane where the stitch exists but a light beam enters obliquely from the upper space, variation of shade is also added in the widthwise direction of a yarn similarly to the longitudinal direction thereof in order to impart three-dimensional feeling thus attaining a simulation image having highly massive feeling.

Abstract: An object of the invention is to provide a simulation method and a simulation apparatus of the image of a twisted yarn capable of forming an image close to the actuality. When the images of twisted threads (1, 2) are inputted, abstracted models (3, 4) of the twisted yarns having a constant elliptical cross-section are obtained as shown in (b). A projected image (6) of the twisted yarns as shown in (c) is obtained when the models shown in (b) are viewed from the right side and one of two abstracted models (3, 4) located on the left side is concealed. The projected image (6) of the twisted yarns is formed by copying the images of the twisted yarns (1, 2) on to parts corresponding to the abstracted models (3, 4) of respective twisted yarns.

Abstract: A weft knitting machine with a movable sinker device capable of preventing yarn from being worn caused by repeatedly striking the yarn with a sinker energized by a spring to push down knitting fabric, wherein a stroke to which a yarn locking part (2a) at the tip of a sinker plate (2) is moved to a tooth port (6) by the energization of the spring (4) is increased at a first stage shown in (a) and decreased at a second stage shown in (b), the stroke is limited in (b) by locking a holding locking part (12a) of a holding member (12) to the holding locking part (2d) of the sinker plate (2), and a stage is switched to a second stage at a knitting portion where the yarn locking part (2a) repeatedly strikes the yarn to prevent the yarn from being thinned and fluffed.

Abstract: A yarn carrier 1 is capable of being engaged with a pin 4 protruding from a carriage 3 at two engagement points 8, 9 separated by a delay amount ?L with respect to a center 1a, respectively. Assuming that the carriage 3 approaches from the right with the pin 4 protruding in order to select and haul the yarn carrier 1 stationary on a yarn guide rail 2, the tip of the pin 4 is guided on a guide portion 11b of an oscillating piece 11, and a tip portion 11c prevents engagement with the engagement point 9 by making oscillation displacement about a shaft 11a. The pin 4 is guided to the engagement point 8 by guide portions 13a, 12a of oscillating plates 13, 12, and abuts on a tip portion 10c of an oscillating piece 10, which is engaged with the front side of the pin 4. The oscillating plate 12 also departs from the pin 4, and a tip portion 12c ascends to be engaged with the rear side of the pin 4.

Abstract: An object of the invention is to quickly display a simulation image of knitting stitches approximate to an actually knitted fabric. When an image is present in the position of the knitting stitches 12, 13 corresponding between an upper layer 1 and a lower layer 2, the images of knitting stitches for pattern 11 or transformed knitting stitches 12, 13 in the upper layer 1 having the highest priority are displayed. In each layer, it is possible to perform an editing operation of selecting combinations of knitting stitches previously registered in a form of module from a library and changing the position and the shape of the image of the knitting stitches. The knitting stitches in the periphery of the knitting stitch for a pattern 11 are substituted for the transformed knitting stitches 12, 13 reflecting the influence of the making of the knitting stitch for pattern.

Abstract: An object of the invention is to improve yarn feeding conditions to a knitting needle and improve a loop pressing function and a yarn holding function for end stitches in a flat knitting machine provided with a compound needle. In a top portion 12 of a loop presser 11 advancing to a tooth mouth 10, a knitting yarn holding portion for end stitches 13 and a loop presser portion 14 are formed. The knitting yarn holding portion for end stitches 13 hides a tongue 25a from the yarn 22 at a wall portion 15 above the knitting yarn holding portion for end stitches 13 so that the problem of yarn entanglement that the yarn 22 fed to a hook 24a of the compound needle 23 from a yarn feeding port 20 is surmounted on the tongue 25a may be solved. A pressing portion 16 below the knitting yarn holding portion for end stitches 13 presses the yarn 22. The knitting yarn holding portion for end stitches 13 holds the yarn 22 outside the end stitch by winding it around it.

Abstract: An object of the invention is to display an image giving a feeling close to the feeling of a knitted fabric actually knitted with a knitting yarn. Linear knitting yarn image data 1 is divided into a plurality of meshes 2. The mesh 2 is made to match a transformed mesh 3 transformed along the shape of a knitting stitch loop 4. The knitting yarn image data 1 is subjected to an image drawing processing by a mesh transforming technique to create the image of the knitting stitch loop 4. A lower section 4a and an upper section 4b are defined in a portion where the knitting stitch loops 4 are overlapped, the portion where the knitting stitch loops are overlapped is synthesized as a knitted fabric 6, and displayed. Fluffiness or the like is also reproduced, and consequently the feeling like that of an actual knitted fabric can be given.

Abstract: An object of the invention is to obtain an intarsia pattern fabric which is not likely to cause yarn entanglement, eliminates the need for divided knitting, and provides good productivity even when a cylindrical knitting fabric is to be knitted. in a double bed flat knitting machine, a carriage and an intarsia carrier capable of knitting with two sets of cams are used to knit two courses of knitting fabric by moving a carriage six courses. An intarsia pattern is knitted at a front needle bed FB, and a knitting yarn between the intarsia carrier halted near a boundary and a knitting needle F is used to perform kick-back of the intarsia carrier by the third-course movement of the carriage. A back body is knitted while the yarn is hooked on an unused knitting needle F in a back needle bed BB. The sixth-course movement of the carriage releases a knitting yarn from the knitting beed F in the back needle bed BB while the back body is being knitted.

Abstract: A three-dimensional model is created without carrying out complicated modeling by incorporating elements of a two-dimensional image into the three-dimensional model. A two-dimensional image inputted to a two-dimensional image input section is stored in a two-dimensional image storing section, while information on a predetermined element of the two-dimensional image is extracted in a processing section in relation to three-dimensional information, and thereafter transformed to three-dimensional information. A three-dimensional modeling data producing section adds the three-dimensional information transformed from the element information to modeling data which expresses a three-dimensional shape which is previously prepared, and thereby creates a three-dimensional model. A rendering section subjects the three-dimensional model thus created to bump mapping, texture mapping or the like, and thereafter, a three-dimensional image is displayed by a display section.

Abstract: A fluctuation in tension of a knitting yarn to be fed is reduced, and the knitting yarn having an accurate length is fed even if the amount of demand for the knitting yarn is suddenly changed. A knitting yarn is interposed between a main roller and a driven roller and is thus fed, and is supplied from a yarn feeding port to a fabric, with storage depending on an inclination of a buffer rod. A yarn feeding controller predicts the amount of demand for the knitting yarn based on a signal sent from a knitting controller and PID controls a servo motor such that a position of a tip portion of the buffer rod aims for a position of an origin according to the inclination angle of the buffer rod, which angle is detected by an inclination angle sensor.

Abstract: A three-dimensional image having a complicated shape is created from a two-dimensional image obtainable by simple drawing. When a drawing operation is carried out using a digitizer, density data to be stored in one of a density layer 0-data memory to a density layer n-data memory is created using a brush shape generated in a brush generating section. A distance up to a reference coordinate point with respect to a primitive shape is initially set in a distance data memory. A distance operating section computes a modification rate for modifying each point on the primitive shape, on the basis of two-dimensional density data selected by a selecting section. The selecting section sequentially reads out multilayered density data, to cause a normal computing section to compute a normal direction on each point on the primitive shape or on the modified primitive shape from data in the vicinity of the point.
