The present invention provides a probe block, which comprises 1) a conductive base on which a first groove is formed, 2) a pair of signal transmitting probes which have dielectric covers and are placed parallel to each other in the first groove, and 3) a ground probe which is in contact with the conductive base, wherein front portions of the signal transmitting probes and the ground probe protrude from the conductive base to form signal transmitting probe needles and a ground probe needle, respectively. The probe block of the present invention has excellent high frequency responses characteristics and is easy for maintenance.

There is provided an imaging device including a detection section which detects motion of the image processing device, a blend ratio calculation section which calculates a blend ratio of a first motion compensation image to a second motion compensation image, the first motion compensation image and the second motion compensation image being determined from a first motion vector and a second motion vector each indicating motion between frames, respectively, based on the motion of the image processing device detected by the detection section, a blend section which generates a motion compensation image by blending the first motion compensation image and the second motion compensation image in accordance with the blend ratio calculated by the blend ratio calculation section, and an addition section which adds the motion compensation image generated by the blend section to a target image.

A weft picking system for an air jet loom is provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers, one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be placed between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns and regulates the posture of the weft yarn under the influence of air jet ejected from the nozzle and from a plurality of sub-nozzles. The rollers always rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being placed between the rollers to a second state of separating from the rollers or vice versa. A weft yarn slackened portion is unavoidably formed between the weft traction device and the weft posture regulating nozzle, due to a temporary difference in the tractive speed between the weft posture regulating nozzle and the weft traction device. A slackened portion deforming device is disposed between the weft traction device and the weft posture regulating nozzle to effectively deform the slackened portion in a manner to smoothen the slackened portion enough as to prevent any trouble in the weaving operation and any defects in the woven fabric.

A weft picking system for an air jet loom provided with a microcomputer as a controller. The weft picking system comprises a weft traction device including a pair of rollers one of which is driven by an inverter motor. A weft yarn fed from a weft measuring and storing device can be put between the rollers to be drawn toward a weft posture regulating nozzle. The weft posture regulating nozzle is arranged to project the weft yarn into the shed of warp yarns while regulating the posture of the weft yarn, under the influence of an air jet ejected therefrom and under assistance of air ejection from a plurality of sub-nozzles. The rollers are always driven to rotate during a weaving operation of the loom. A change-over device is provided to change the weft yarn from a first state of being put between the rollers to a second state of separating from the rollers or vice versa. The changing from the second state to the first state of the weft yarn is made after the starting of ejection of the fluid jet from the weft posture regulating nozzle in a weft picking cycle thereby preventing the weft yarn from being slackened in a location between the weft traction device and the weft posture regulating nozzle.

An electrostatic recording material, capable of recording clear resist marks and colored images without generating a lead edge fog and colored image slippage, comprises an insulating support 1, an electroconductive intermediate layer 2 formed on a surface of the support, a dielectric layer 3 formed on the electroconductive intermediate layer, and a pair of electroconductive side edge layers 4, 5 formed on a record-starting side edge portion of the dielectric layer, in which side a recording operation in a transversal direction of the recording material is started, and on a record-ending side edge portion of the dielectric layer, in which side the recording operation is ended, extending along the longitudinal axis of the recording material, spaced from each other, and each having a surface resistivity of from 1.times.10.sup.4 to 5.times.10.sup.5 .OMEGA.; the electroconductive record-starting side edge layer having a surface resistivity ratio of 2:1 to 10:1 to the electroconductive record-ending side edge layer.

In a jet weaving loom having a frame, a reed holder pivotally movable relative to the frame in the downstream and upstream directions with respect to the motion of the warp threads, a jet nozzle mounted on the reed holder to move therewith and ejecting the weft thread into the shed of the warp threads by the jet action thereof, and a weft gripper secured to the frame for selectively gripping and releasing the weft thread advancing toward the jet nozzle, so that when the reed holder moves in the downstream direction toward a first extreme position, the beating and the weft cutting are carried out, and when the reed holder moves in the upstream direction and comes to a second extreme position, the weft picking is actually carried out, there is provided a weft pull-back device which catches the weft thread extending between the weft gripper and the jet nozzle when the reed holder is positioned in the vicinity of the first extreme position, and holds the same for a predetermined period of time when the reed holder moves in the upstream direction toward the second extreme position after completing the beating and the weft cutting.

A weft detaining device of a shuttleless loom, comprises a drum on which a weft yarn is wound predetermined times prior to a weft picking through a weft picking means, the drum being constituted by a plurality of separate and independent pieces, a support member on which the drum separate pieces are securely supportable, and a device for allowing the location of each drum separate piece to be movable relative to the support member so that the outer diameter of the drum is adjustable, thereby making possible changing a weft picking length by merely changing the location of each drum separate piece, without replacing the drum with the other drum having a different diameter or using any members to be mounted on the peripheral surface of the drum to adjust the outer diameter of the drum.

Weft detaining device of shuttleless loom

A weft detaining device of a shuttleless loom, including a drum having a frustoconical section and a cylindrical section, a first catching member for catching the weft yarn on the drum in the vicinity of the border between the frustoconical and cylindrical sections for at least a period of weft pickings, a second catching member for catching the weft yarn on the drum for at least a period of the first time weft picking in sequential twice weft pickings and releasing its catching action to the weft yarn for at least a period of the second time weft picking of the sequential twice weft pickings, and a third catching member for catching the weft yarn on the drum cylindrical section for at least a period wherein the detaining of the weft yarn for the succeeding twice sequential weft pickings is completed, thereby enabling a so-called dual-pick pass weft insertion though the weft detaining device is of the drum type.
