Abstract: The present ball/roller bearing cleaning method is a method which, using cleaning liquid 24, cleans a bearing to be cleaned 1 composed of an inner ring 1b, an outer ring 1a, a rolling bodies 1c and a retainer. In the cleaning method, the cleaning liquid 24 is made to flow through the bearing to be cleaned 1 from the axial direction of the present bearing 1 into spaces in which the raceway surfaces of the inner and outer rings 1b and 1a of the bearing to be cleaned 1 surround the rolling bodies 1c and retainer. For example, a cylindrical-shaped rotary die 2 having spiral grooves 2a is interposed into a cleaning liquid supply passage, and the cleaning liquid 4 is supplied to thereby rotate the cylindrical-shaped rotary die 2, whereby the cleaning liquid having high pressure can be supplied to the bearing to be cleaned 1 from the cylindrical-shaped rotary die 2.

Abstract: In a ball bearing having an inner ring and an outer ring independently supported in a relative displacement manner, balls are arranged by placing the balls in an annular space between the inner ring and the outer ring, placing nozzles beside the inner ring and the outer ring, the number of which is at least the same to that of the balls, making each of the nozzles face the opening on one side of the annular space between the inner ring and the outer ring, and causing stream of fluid by each of the nozzles to make the balls move circumferentially, so that the balls are arranged circumferentially with a uniform interval, wherein when the stream is caused by each of the nozzles, one of the inner and outer rings is relatively displaced with reference to the nozzles and the other ring, so that the relationship in position between the nozzles and the balls is changed.

Abstract: A ball bearing inspection apparatus 1 comprising: a rotation shaft3 fitted to one (for example, inner race 7) of inner and outer races 7 and 9 for rotating one race while limiting the movement of one race in an axial direction of the rotation shaft 3; a press plate 13 disposed on an opposite side of the rotation shaft 3 with respect to a ball bearing 5 for pressing the other race (for example, outer race 9) in the axial direction of the rotation shaft 3 while limiting the rotation of the other race; and a press-back plate 33 provided so as to be movable in the axial direction of the rotation shaft 3 for pressing back the other race in a direction reverse to the pressing direction of the press plate 13. Hence, the ball bearing inspection apparatus can inspect a large area of ball surfaces in a short time at one installing try.

Abstract: A preload measuring apparatus to measure the preload of a rolling bearing that includes a bearing support, a pressurization device, an excitation device, a vibration sensor, and a control section. The bearing support supports a rolling bearing by supporting both ends of a shaft inserted into an inner ring of the rolling bearing. The pressurization device loads a predetermined weight in the axial direction onto the rolling bearing. The excitation device applies vibration onto the rolling bearing by the drive of the piezoelectric elements. The vibration sensor detects the vibration generated on the rolling bearing by the vibration application of the excitation device. The control section operates the excitation device in the situation that the pressurization device presses the rolling bearing, and obtains the resonance frequency by the output signal from the vibration sensor and calculates the preload of the rolling bearing according to the obtained resonance frequency before the predetermined weight as loaded.

Abstract: In a tendency search phase, the user tentatively selects at least a predetermined number of plural images among displayed images. A computer system checks keywords of the tentatively selected images, which have been registered previously in an image database, in order to extract a common keyword that is common to the tentatively selected images. The computer system subsequently allocates first priorities to a plurality of images to be displayed as next candidates, based on the closeness of the images to the common keyword. In a relation extraction phase, the computer system displays the tentatively selected images as well as at least part of the plurality of images to be displayed as next candidates according to the first priorities. The user definitely selects at least one image among the plurality of images thus displayed.

Abstract: Each image area in a total image is assigned with a screen angle mode Ms indicating whether screen angles of magenta and cyan separations are to be adjusted or not. Screen angle data representing screen angles of magenta and cyan are produced according to the screen angle modes Ms. A dot signal for recording a halftone image of each of the magenta and the cyan separations is generated by comparing screen pattern data of a certain screen angle specified by the screen angle data with image data for each color separation. Accordingly, the present invention effectively prevents a moire in any image area included in a printing image.

Abstract: An image is read by an image reader and displayed on a color display. A segment (S) (or other graphic) is designated on the displayed image. Areas which overlap the segment and which have a designated color are specified as objective areas. The colors of the objective areas are changed to a newly designated color.

Abstract: An image approximate to a vignette is to be generated from image data representing a first set of color steps CS1. A second set of color steps CS2 is first created from the first set of color steps CS1, where the second set of color steps CS2 has a plurality of figures inserted at equal intervals between two end figures of the first set of color steps CS1. Binary noise data BS are then generated in the vicinity of the boundary of each figure of the second color steps. Vignette image data VID approximately representing a vignette is generated by adding the binary noise data BS to bit map data of the second set of color steps CS2. Accordingly, a tone jump is eliminated from the image approximate to a vignette.

Abstract: A shadowing process in which offset values .DELTA.x and .DELTA.y indicating a gradient and a range of the shadowing effect are set as shadowing parameters. A target linework image area G is extracted from original image data on an n-th scanning line. On the next (n+1)-th line, a shadow pixel S1 is obtained for a start pixel GO of the target linework image area G according to a gradient k calculated by the offset values .DELTA.x and .DELTA.y. A shadow line segment on the (n+1)-th scanning line is determined based on the shadow pixel S1 and a length L of the target linework image area G. Shadow line segments are determined for (n+2)-th and (n+3)-th scanning lines in the same manner. The shadow line segments are combined to make a shadow area S.

Abstract: Each image area in a total image is assigned with a screen angle mode Ms indicating whether screen angles of magenta and cyan separations are to be adjusted or not. Screen angle data representing screen angles of magenta and cyan are produced according to the screen angle modes Ms. A dot signal for recording a halftone image of each of the magenta and the cyan separations is generated by comparing screen pattern data of a certain screen angle specified by the screen angle data with image data for each color separation. Accordingly, the present invention effectively prevents a moire in any image area included in a printing image.

Abstract: An overlapping image area is generated on a boundary between a linework image and a picture image by processing one-page linework data and one-page picture data previously prepared without the overlapping process. The overlapping process includes an outer mode and inner mode. In the outer mode, the linework data is corrected such that an overlapping image area is produced in an effective linework area of the one-page linework image, and the picture data is corrected such that an effective picture area is expanded in the one-page picture image. The corrected picture data and corrected linework data are then combined with each other to form a final composite image.

Abstract: The present invention forms overlapping regions on the boundaries of neighboring image regions in a block copy image. In the method of the invention, region numbers are allocated to separate image regions in an original image, and overlapping regions or frame regions of a predetermined width are created on the boundaries of the neighboring image regions while alternately applying an eight-neighbor window and a four-neighbor window (S52 and S57 ). Each window includes a center pixel and neighboring pixels with a predetermined priority. Region numbers are allocated to the frame regions based on the region numbers of the center pixel and the neighboring pixels and on the priorities. The color of each frame region is determined according to a predetermined method, which depends on printing types such as offset printing and gravure printing.

Abstract: An image processing apparatus functions to convert a first image derived as color-pixel data into a second image generated by a lesser number of corresponding data through a pixel-skipping process. The first image data is segmented into pixel blocks each consisting of a plurality of the color-pixel data relative to the number of second-image pixels to be generated. Each pixel block corresponds to one pixel composing the second image, and serves as an objective block from which the data to produce the corresponding second-image pixel is determined. If this determination cannot be made, the relevant color-pixel data is determined by comparative reference to color data of both the objective pixel block and that of adjacent pixel blocks. Original dot and fine-line features of the first image are thus maintained in the pixel-skipped second image.

Abstract: An image data extracting circuit extracts multi-gradation image data obtained by reading a binary original by prescribed image regions about a pixel to be processed and latches the same. A linear edge detecting circuit detects a pixel to be processed corresponding to a linear edge portion of the original that is in conformity to the scanning direction by mutually comparing the gradients of the respective latched pixels. The circuit outputs a signal expressing linear edge patterns thereof and a signal expressing the gradient, i.e., density thereof. A second high-resolving circuit receives the signals to generate high-resolution binary image data forming a smooth linear edge having a resolution higher than the read resolution with an average density in response to the gradient of the pixel to be processed.

Abstract: Disclosed is a water-surface target towed by a mother ship which comprises a towed member running underwater with a ballast weight suspended therefrom, a target pole set up on the top of the towed member, and a stabilizing plate attached to a position above the waterline of the target pole at an angle of incidence. The water-surface target can be used even under bad conditions and towed at a high speed, e.g. 30 knots, due to the towed member being capable of continually maintaining stability underwater.
