Filed: 1989-01-31
Abstract: PURPOSE:To prevent a printed surface from contamination by providing an insulating sheet that approaches a copying part on the edge of the under surface of a metallic movable guide plate, from which the insulating sheet is projected. CONSTITUTION:A guide roller 46 by which a copying paper that passes between a fixed guide plate 34 and a movable guide plate 35 is placed along an image holding body 24, is held on one side of a copying part 15 so as to rotate freely. Although the guide roller 46 is close to an insulating sheet 47, it is maintained in a non-contact state. The sheet 47 is small in the area so as to touch only the copying paper near the copying part 15, and is also thin, so that the capacity of static electricity generated by the contact with the copying paper is low, and adhesion of developer and paper powder are alleviated thereby. The copying paper is guided just before the copying part 15 by the sheet 47. Developer is adhered to the roller 46, too, for the developer of the image holding body 24 is attracted by the copying part 15, however, even if the developer adheres to a non-printed surface of the copying paper, since the roller 46 approaches the sheet 47 in a non-contact state, the developer adhered to the roller 46 is not adhered to a printed surface of the copying paper through the sheet 47.

Filed: 1985-02-08
Abstract: PURPOSE:To increase the maximum turn-off currents ITGQM of a GTO largely by burying a metallic layer into a P base layer and connecting the metallic layer to a gate electrode. CONSTITUTION:A metal is buried into grooves 6 in a P-type Si substrate 1-1. An Si substrate 1-2 consisting of P-N-P three layers is prepared. Surfaces to be bonded of both substrates are mirror-polished, and mirror surfaces are bonded mutually through degreasing, the removal of contaminated films, washing by water and centrifugal drying, and unified at 1,000-1,200 deg.C. A P layer 4 is polished in predetermined thickness, P is diffused to shape N<+> layers 5a, 5b, and an etched groove 20 reaching the metallic layers 6 is formed in the layer 4. An anode electrode 7, cathode electrodes 8 and gate electrodes 9, 10 for a turn- OFF are attached. According to the constitution, currents are sucked out of gates on a gate turn-OFF, and lateral resistance in a P base layer is reduced remarkably, thus largely increasing ITGQM. Zener currents may not be flowed after the turn-OFF, and the temperature rise of the gate sections is also inhibited, thus resulting in effectiveness of operation at high frequency.

Title: Light control element
Inventor: NITTA MASAAKI
IPC: G02F1/055
Filed: 1987-02-02
Abstract: PURPOSE:To prevent a light control element from generating unrequired light transmission or crosstalk by etching an area in the vicinity of a boundary between a part other than a light control part and the light control part to remove the area. CONSTITUTION:Areas other than pixels 7 in an optical shutter array (b) are usually independent of the mounting areas of counter electrodes 35, 36 and light control. Although the electrode mounting areas are made opaque areas by the electrodes 35, 36, areas 18 between adjacent pixels 7 are removed by etching. Since the areas 18 between respective pixels 7 in the crystal 34 are etched, no PLZT crystal exists in the areas 18 and optical modulation is not generated even if electric fields between both electrodes 35 and 36 are partially applied to the non-light control area 18. Thereby, the generation of unrequired light transmission or crosstalk can be prevented.
