Abstract: A twisting nematic liquid crystal display apparatus (1) rotates the plane of polarization of the light with optical rotatory power of liquid crystal layer (2), thereby display operation is made by switching pass/interruption of the light by means of a pair of polarizers (8a, 8b) sandwitching the liquid crystal layer (2). At this time, by associating an optical compensating member (3) whose optical anisotropy is in the opposite characteristic with a liquid crystal display device, leakage of light and coloration caused by birefringence and optical rotatory dispersion in the liquid crystal layer (2) are prevented, the switching characteristic of the light over the entire visible light region is enhanced, and color display is high in contrast ratio. Since the optical compensating member (3) is formed of laminated and adhered plural synthetic resin films which are extended monoaxially, and twisted in the opposite direction to twisting direction of liquid crystal molecule on the plane including the extending direction, the quality of display may be improved without deterioration of the advantages of the existing liquid crystal display apparatus such as small size and portability.

Abstract: An improved semiconductor AC switch (30) is described having internal bias generation for the power MOSFET switches (40,42) and isolated control input (84). Dual power MOSFETS (40,42) with substrate diodes (46,48) are connected in series between source (32) and load (36). DC gate bias for the MOSFETS (40,42) is derived from an internal power supply (60,92,102) containing energy storage (68,72,98) which charges from the line, typically every half cycle. The gates (50,52) of the power MOSFETS (40,42) are tied to the internal bias generator (60,92,102) through a voltage divider network (58,62,114) containing a variable resistance (63,109) controlled by an optical input signal (82). The internal energy storage (68,72,98) may be a capacitor (68,72) or solid state battery (98), preferably a monolithic thick or thin film battery (98). No transformers or external control bias generators are required and the resulting switch is particularly simple and compact.

Abstract: A feeding device in accordance with the present invention comprises an arm (32) mounted such that one edge thereof is rotatably supported and that is capable of moving freely in the horizontal plane, a rotating section (35) that is rotatably supported by the other edge of the arm (32) that is capable of rotating freely in the horizontal plane to at least two paper feed positions, i.e. longitudinal and lateral feed positions, and that comprises a pivotal paper holding plate (34) that is capable of rising, a rotating device that is rotatably mounted in the vicinity of a corner of the rotating section (35), moves back and forth in a straight line in a direction orthogonal to the paper feed direction and permits the rotating section (35) to rotate, and a flexible joint that is capable of pivoting in at least two directions and that supports the pivotal paper holding plate (34) at one point located in the corner formed by the non-feeding side of said the rotating section (35) when the rotating section (35) is set in the longitudinal feed position and the non-feeding side of the rotating section (35) when the rotating section (35) is set in the lateral feed position, and such that the pivotal paper holding plate (34) uses the non-feeding sections as fulcrums when the pivotal paper plate (34) pivots and rises. As a result, the feed position of the copy paper may be changed smoothly and accurately, and 
the leading edge of the copy paper is always placed in the same position when the copy paper is set in the different feed positions, without causing the device to be large or the operation of the device to be complex. 
The present invention further comprises a guiding device (37) that includes a sustaining member (37b) provided with guide holes (37c) formed vertically and a guide bar (37a) extending on one of the paper non-feeding sides of the pivotal paper holding plate (34) and engaged in the guide holes (37c), that serves as guide to the pivotal paper holding plate (34) when one of the paper feeding sections of the pivotal paper holding plate (34) is being lifted, and that serves as fulcrum for the pivotal paper holding plate (34) when the other paper feeding section of the pivotal paper holding plate (34) is being lifted. Consequently, the copy paper may be prevented from being fed in a shifted position during the feeding operation performed after the pivotal paper holding plate (34) was pivoted and raised.

Abstract: A device is disclosed for automatic taking-out of articles, in particular of containers from a roller conveyor. The device contains a pivotable rocker which, at its discharge end, carries a stop device for the containers situated on the roller conveyor. Arranged at the other end of the rocker is an overrun device which, in the unpivoted state of the rocker, lies under the conveying plane of the roller conveyor. As a result of the pivoting of the rocker, the stop device is lowered and the front container can be removed from the roller conveyor, while the subsequent container can be prevented from further movement by the overrun device. After the removal of the container, the rocker pivots back into the initial position and the subsequent container is conveyed on to the stop device at the end of the roller conveyor. <IMAGE>

Abstract: Line trunk groups exist in duplicate for dependability reasons. The through connection of the input lines to the switching network can thus run via different signal paths. To avoid interference during the switch-over, the interfaces concerned are provided with compensating buffers. The data contained therein are read in and out phase- and frame-synchronously with a uniform clock. This uniform clock is obtained from the basic digital TDM switching system clock. Due to transit time distortions and component tolerances, this basic clock must be regenerated by the circuit arrangement according to the invention before it is applied to the compensating buffer.
