Abstract: End portions of lower-side telescopic friction plates 61, 61 which lie to face a front side of a vehicle body are connected integrally by a connecting portion 612, and a lower end 617 of the connecting portion 612 is fixed to an outer circumference of an upper-side lower column 10A by means of welding. When an upper column 11 is fastened on to a vehicle body mounting bracket 3 for tilt and telescopic positioning of the upper column 11, the lower-side telescopic friction plates 61 and upper-side telescopic friction plates 62 are fastened together. The upper column 11 and the lower column 10 are connected together via the lower-side telescopic friction plates 6 and the upper-side telescopic friction plates 62, whereby the rigidity and vibration properties of a steering apparatus as a whole are enhanced.

Abstract: To provide a steering apparatus which can ensure the transmission of rotational torque of a steering shaft even when weld joining between a shaft and a shaft coupling is insufficient. An extension shaft 4 is inserted from the other end 512 of a joining tubular portion 51, so that male serrations 41 formed on the extension shaft 4 are brought into engagement with female serrations 52 and a shank portion 42 of the extension shaft 4 is tightly fitted in a fitting hole 53. Next, the other end 512 of the joining tubular portion 51 and an outer circumference of the shank portion 42 of the extension shaft are welded to be joined together, so as to forma weld joining portion 56. Following this, a male intermediate shaft 16A is coupled to a shaft coupling 5 which is joined integrally with the extension shaft 4.

Abstract: Disclosed herewith is a telescopic type steering device that is high in vibration rigidity and good in feeling of steering has a lower column; an upper column telescopically coupled to the lower column; a steering shaft assembly having an upper axle member for mounting a steering wheel at the upper end and a lower axle member spline-coupled with the upper axle member so as to transmit steering torque to a steering mechanism of a car body from the wheel through the upper and lower axle members; a lower bearing for rotatably supporting the lower axle member at the lower side; an upper bearing for rotatably supporting the upper axle member at the upper side; and an intermediate bearing for rotatably supporting the steering shaft assembly at an intermediate position between the upper and lower bearings.

Abstract: When there travels a vehicle equipped with a steering apparatus with a heavy constant velocity universal joint, e.g. double Cardan joint or Rzeppa joint, vibrations of the wheels and the vehicle body cause the joint to vibrate. A vibratory moment applied to the pinion shaft caused by the vibration provokes undesirable engagement of the pinion and the steering rack. A steering apparatus of the present invention is provided with an elastic coupling between the joint and the pinion so as to prevent the vibration from being transferred and absorb the vibration.

Abstract: A steering intermediate shaft has an inner shaft member and an outer tube member so engaged with each other as to be capable of transmitting rotation and to be slidable in an axial direction. The outer tube member includes slits so formed at one end as to extend in the axial direction. An annular fastening member is provided at a portion of the outer tube member formed with the slits to exert a fastening action inwards in a radial direction. The fastening member includes a disengagement preventing member for preventing the outer tube member from disengaging from the inner shaft member against an axial force within a predetermined value by engaging with the inner shaft member.

Abstract: Disclosed is a device for producing embroidery data on the basis of image data, wherein jump threads extended between unit images are effectively prevented from being stitched into the embroidery stitches by using particular stitch data produced by successively searching the image data from above to set a stitch starting point of each unit image. The stitch data forms the stitches starting from the stitch starting point and terminating at the stitch starting point. Although the jump threads are produced between the stitch starting points, these jump threads will not be stitched into the embroidery stitches.

Abstract: Disclosed is a device for producing embroidery stitch data on the basis of image data, wherein an image is read in by use of an image scanner and is divided into a plurality of latticed sections. The latticed sections are all searched through one after another and discriminated if each of the sections is stitched or not. Unit stitch patterns are selected to be stitched in the sections respectively which have been discriminated to be stitched, the selected unit stitch patterns including at most two patterns which have different initial stitch points and different end stitch points and are located in predetermined sections respectively.

Abstract: An embroidering position setting device and method of operation thereof for an embroidering sewing machine are described. The embroidering sewing machine is capable of storing pattern data in a memory for a plurality of embroidery patterns which can be selectively read out to operate a stitch forming device to form the stitches of a selected pattern or patterns on a cloth to be stitched. An embroidering frame has a cloth extended thereon to be embroidered and is connected to an X-Y drive mechanism, said cloth having a mark located at an optional position for representing a reference embroidering position of the cloth. Jog keys are selectively operated to operate said X-Y drive mechanism thereby to shift said embroidering frame so that said reference embroidering position mark of the cloth may be located at the position under said machine needle in vertical alignment therewith.

Abstract: Marks such as patterns, designs, numbers, or the like are cut out of a mark sheet or mark sheets placed on a glass base by a thermal cutter having a heated cutting bit. The thermal cutter is movable two-dimensionally over the mark sheet, and is also vertically movable between an upper position in which the thermal cutter is lifted off the mark sheet supported on the base and a lower position in which the thermal cutter is lowered in contact with the mark sheet supported on the base. The thermal cutter is angularly movably supported on an eccentric shaft that is rotatable by a stepping motor. The thermal cutter has a cutting bit resiliently urged by a spring for stable positioning. A range or ranges in which desired marks are to be cut out of a mark sheet or mark sheets can be confirmed by being traced by the thermal cutter before the marks are actually cut out. When mark numerals indicative of desired numbers are to be cut out, such mark numerals are rearranged and displayed for the operator's information.

Abstract: An original picture pattern to be produced with an embroidering machine may be seen through a transparent touch panel of an input device detachably connected to the embroidering machine. By simply tracing the coutour lines of the pattern with a stylus pen, the coordinates of substantially continuous points of the pattern may be inputted. A series of the coordinate data thus inputted is converted to another series of the coordinate data representing actual stitch points of a pattern to be produced on the fabric as a boldfaced duplicate of the original picture. Each line of the pattern may be boldfaced with zigzag stitches extending over a selectable amplitude or with multiplicated straightaway stitches formed by a repeated straight line producing operation.
