When generating a projection image by setting a plurality of search points in an intended display area of a three-dimensional image along a plurality of visual lines, each connecting each pixel on a projection plane on which the three-dimensional image is projected and an arbitrary viewpoint, calculating a pixel value of each search point by an interpolation operation based on pixel values of adjacent pixels of each search point, and determining a pixel value of each pixel on the projection plane with respect to each visual line based on the calculated pixel value of each search point, if an adjacent pixel of a search point is a pixel in an unintended display area, the pixel value of the search point is calculated such that the pixel value of the pixel in the unintended display area does not contribute to the calculation, thereby preventing an artifact arising from the unintended display area.

When generating an intermediate image which is an image in the middle of changing from one to the other of two pseudo three-dimensional images generated by ray casting a three-dimensional image from an arbitrary viewpoint under two different opacity level setting conditions, determining an opacity level setting condition by determining an opacity level to be allocated according to each pixel value such that a variation in the opacity level for a change in a changing phase of the intermediate image become smaller as the changing phase approaches closer to a pseudo three-dimensional image generated under either one of the two different opacity level setting conditions in which a smaller value is allocated as the opacity level to be allocated according to each pixel value, and generating an intermediate image by ray casting the three-dimensional image from an arbitrary viewpoint under the determined opacity level setting condition.

A needle selecting apparatus for a weft knitting machine capable of performing a needle selecting position locking function without moving a selecting jack forward and backward is provided. In the needle selecting apparatus, as shown in FIG. (a), an initial position of the selecting jack (22) is set at a welt position to ready for non-operation. And, as shown in FIG. (b), when a butt (22a) is pressed by a B presser (27) of a carriage (33), the selecting jack (22) comes into a locked condition by a locking member (30). The selecting jack (22) is sunk into a needle groove (35) in the locked condition and the butt of a knitting needle is also sunk into the needle groove (35) to separate from a knitting cam. When a knitting position or tucking position is selected by a needle selection actuator (25), a selector (23) is driven by a selector cam (24), and a tip (22d) of the selecting jack (22) presses a contact portion (22e) of the selecting jack (22) to move the selecting jack rightward. During the movement, the locking member (30) is drawn to release the locked condition.

A break in twice as many yarns is made detectable merely by slightly modifying the tension switch assembly of a knitting machine. A yarn conductor 20 is rotatably attached to the forward end of an arm 16 of the assembly and provided with a pair of yarn supports 26, 27 on opposite sides of a rotational pin 19. Upon a break occurring in the yarn 2 retained on one of the yarns supports 26, 27, torques exerted by the yarns 2, 2 on the respective supports 26, 27 are brought out of balance to rotate the yarn conductor 20 and release the remaining other yarn 2 from the support 27.

A yarn feeder comprises a switching mechanism which presets a swing direction of the yarn feeding port after completion of a yarn feeding operation, and, after having completed yarn feeding operation, changes over the swing of the yarn feeding port from one yarn feeding position to another standby position interlocking with the released selective operation of the entraining means, in which the switching mechanism includes a feeder rod having a yarn feeding port at its lower end, which is composed of at least two members, both of the members being arranged to relatively slide each other in a vertical direction and provided with a push-up member to force upward respectively. The switching mechanism includes a support member for bearing the yarn feeding rod being provided with a regulation unit for regulating the upward movement of the yarn feeding port in the determined standby position, wherein the rise of the yarn feeding port in the standby position is limited below the determined altitude by using the regulation unit.

According to a distribution of image data values corresponding to individual spatial coordinate points on a three-dimensional space obtained when a region to be observed is tomographically taken by a radiographic medical diagnosis system, an interpolation area is provided within a segment set within a range of the image data values. In the interpolation area, degrees of chromaticity and opaqueness of each spatial coordinate point are made variable in response to the magnitude of image data value. The degrees of chromaticity and opaqueness of all the spatial coordinate points located on each line of sight connecting each plane coordinate point on a two-dimensional projection plane and a point of view are respectively integrated, and thus integrated values are reflected on the plane coordinate points on the line of sight.

On each of carriages are disposed a group of transfer cams and a group of receiving cams. A leftward movement of the carriages makes it possible to transfer a knitted loop from a front needle bed provided with one carnage to a rear needle bed provided with another carriage. A rightward movement of the carriages makes it possible to transfer the knitted loop from the rear needle bed provided with the other carriage to the front needle bed provided with one carriage. The transferring can be freely carried out between the needle beds, and it is possible to temporarily place a knitted loop from one needle bed to another needle bed and keep a holding, and further retain the knitted loop separately from a fabric being knitted on the other needle bed and when needed, return the knitted loop from the other needle bed to the one needle bed.
摘要:
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).
