Title: Printer
Inventor: KARASAWA KAZUHIRO
IPC: G03G15/00
Filed: 1989-06-19
Abstract: PURPOSE:To omit the waste of sheet feeding by a page unit by means of an eject operation and to prevent picture contamination caused by the contamination of a sheet feeding roller by performing flash light emission at the time of a skip operation for positioning perforations. CONSTITUTION:The printer is provided with a flash fixing unit 3. In the skip operation for positioning the perforations of a sheet to be printed at the time of print travelling, it detects the rotation of the sheet feeding roller 5 which is rotated following a sheet and on a following side and emits a light when a sheet presence/absence sensor detects sheet presence at the entrance of the fixing unit 3 and a skip switch is pressed. Then, by performing the flash light emission and skip fixation, the process of travelling and fixing a white sheet per page by the eject operation in case travelling is stopped from difficulty as a result of not assuming perforation positions is omitted. Thus, the contamination of the sheet feeding roller and of image data can be prevented even when the eject operation is insufficiently performed or not performed.

IPC: G02F1/13
Filed: 1988-06-24
Abstract: PURPOSE:To prevent the generation of zigzag defects in a domain and to obtain uniform display and driving characteristics by arranging plural layers continuously in parallel with each other in multiple directions at the phase of the temp. higher than the temp. of the liquid crystal phase indicating a ferroelectric property, then cooling the layers to the liquid crystal phase indicating the ferroelectric property from the high-temp. phase. CONSTITUTION:A liquid crystal mixture is injected in an isotropic liquid state into cells and after all the liquid crystal materials are injected into the cells, an injection port is sealed at the time of injection. The cells are thereafter slowly cooled down to the liquid crystal phase state at which a ferroelectric liquid crystal is exhibited. The temp. is lowered from the liquid state to the phase of the temp. higher than the liquid crystal phase of the ferroelectric liquid crystal and the smectic layers begin to be formed simultaneously in this stage. The smectic layers are parallel with each other in a certain region at this time. The stripe patterns corresponding to the spiral pitch are observed when the temp. is further lowered down to the smectic C phase. The liquid crystal parts being to be freshly generated from the part of the liquid state and the microdomains are similarly formed when the temp. is further lowered. The entire part of the cells can be embeded with the microdomains. The generation of the defects which have optically serious effect such as zigzag defects is obviated and the uniform display characteristic and the uniform liquid crystal driving are enabled in this way.

Title: Compensation circuit for lateral pincushion distortion
Inventor: SHIMODA KIYOUJI
IPC: H04N3/233
Filed: 1980-11-08
Abstract: PURPOSE:To compensate a lateral pincushion distortion without damaging horizontal scanning linearity, by not utilizing saturation characteristic but using a general transformer. CONSTITUTION:The primary winding of a transformer 7 is so connected that the current is supplied in a direction opposite to that of the deflection current flowed to a horizontal coil 5 of a deflecting yoke. Meanwhile, a horizontal output transistor 1 supplies a saw tooth current of a constant amplitude with the horizontal coil 5 of the deflecting yoke as a load. Thus, a current obtained by subtracting the current, which is supplied from the secondary side to the primary side of the transformer 7 for correction of pincushion distortion, from the current supplied by the horizontal output transistor 1 is flowed to the horizontal coil 5 of the deflecting yoke. Further, the parabolic waveform of a vertical scanning period is superposed to this current flowed to the horizontal coil 5. A phase adjusting circuit 16 adjusts the phase of pulses inputted to a transistor 15 so that this phase coincides with the phase of the saw tooth wave current flowed to the primary winding and the secondary winding of the transformer 7 for correction of pincushion distortion.

Abstract: PURPOSE:To prevent damage to the edge of positioning holes by positioning pins. CONSTITUTION:A workpiece 1, such as a lead frame, having a positioning hole 12, is placed on a table 2 and plunged UP by a positioning pin 5 from below. A guide hole 4 is formed in the table 2 to guide the positioning pin 5, which is composed of the rod of a cylinder 10. An ultrasonic vibrator 14 is secured on the cylinder 10, and vibrates the positioning pin 5 by ultrasonic waves through ON operations (13). Being vibrated by ultrasonic waves, the positioning pin 5 is inserted into the positioning hole 12 in the workpiece positioned on the table 2. The edge of the positioning hole 12 is supported by the tapered portion 6 of the positioning pin 5 and is being vibrated by ultrasonic waves. Therefore, the edge of the positioning hole 12 drops along the slope, and the workpiece is properly positioned even if the positioning hole 12 is initially out of place. This does not exert large force on the edge of the positioning hole 12, and thus does not deform (damage) it.
