    Abstract: A device for use with a Jacquard machine is disclosed which may eliminate the pattern cards, may be made compact in size, may find a wide application, and may considerably increase the weaving speed. In opposed relation with a plurality of needles is disposed a selection mechanism in which a plurality of solenoids equal in number to the needles are disposed in opposed relation with a plurality of armature members equal in number to the needles and interconnected therewith through wires. A control unit is adapted to selectively energize the solenoids depending upon the desired fabric patterns while the armature members are moved toward and made into contact with the solenoids in synchronism with the weaving operation of the power loom so that the selectively energized solenoids attract the armature members to hold their corresponding needles in position while the remaining needles corresponding to the de-energized solenoids are returned to their initial positions. The hooks corresponding to the needles returned to the initial positions are made into engagement with their corresponding knives in a knife box so that when the knife box is lifted, they are also lifted to lift the desired warp yarns, thereby forming a desired shed.

    Abstract translation: 公开了一种与提花机一起使用的装置，其可以消除图案卡，可以制造尺寸紧凑，可以获得广泛的应用，并且可以显着增加织造速度。 与多个针相对的关系设置有选择机构，其中与针数相等的多个螺线管相对于与针数相等并且通过线相互连接的多个衔铁构件相对设置。 控制单元适于根据期望的织物图案选择性地激励螺线管，同时衔铁构件与电动织机的织造操作同步地朝向并与其形成接触的螺线管，使得选择性激励的螺线管吸引衔铁构件 以将相应的针保持在适当位置，而对应于断电螺线管的剩余针返回到其初始位置。 对应于返回到初始位置的针的钩子与刀盒中的相应刀片形成接合，使得当刀盒被提起时，它们也被提升以提升所需的经纱，从而形成所需的梭口。

    Abstract: In a method of preparing color separation printing patterns from a multi-color original design, the design is irradiated by light and multi-color light components reflected from minute picture elements constituting the design are detected. The detected light components are converted to picture element data representative of the optical energy level of the reflected light corresponding to each picture element. The picture element data are stored and filtered to form quantized picture element data indicative of several series of reflected light components respectively falling within different preselected ranges of color. This is done by comparing successive picture element data to detect significant differences in energy level indicative of color changes. The reason for each substantial difference in output level is determined, e.g., pattern defect or imperfection, and the filtered picture element data are stored along with change codes indicative of the reason for the difference. The color of the filtered picture element data is identified by comparison with predetermined stored sample color data. The picture element data are then modified in accordance with the change codes to comply with particular printing conditions or to correct the determined imperfections or defects arising in the original design before the data are supplied to a photomodulator which modulates a laser beam impinging on a photosensitive film for black-and-white reproduction of a predetermined identified color of the original design.

    Abstract: PURPOSE:To simplify and lighten a mechanism for rotary drive in each joint by rotatably and drivably connecting the finger piece on the head side in relation to the finger piece on the base side in each joint by means of an ultrasonic motor. CONSTITUTION:Necessary motion is given to each finger of a hand for a robot by the control by means of ultrasonic motors 16 through 19 and 36 through 38 rotatably and drivably connecting finger pieces 11 through 14 and 31 through 33 respectively in the respective joints. The use of the ultrasonic motors 16 through 19 and 36 through 38 of large torque compared with dead weight and volume eliminates gears for low speed torque and high speed torque and brakes for keeping static state for driving each joint, while reducing the number of components and lightening the mechanism.
