Title: Matrix type plate display device
Inventor: ADACHI KATSUMI
IPC: G09G3/20
Filed: 1988-06-17
Abstract: PURPOSE:To operate the title device with high-speed clocks by delaying the clocks in corresponding to the delay of a start pulse between signal line driving ICs. CONSTITUTION:Clocks become dull in waveform and, at the same time, are delayed by means of an LPF (low-pass filter) constituted of resistances 206 and 207 and capacitor 209 between signal driving IC 108 and 109. Therefore, the clock of the driving IC 109 delayed from the driving IC 108 by the LPF can catch a start pulse and the IC 109 can operates normally. When patterns of a clock wiring section 114 and electrode section 201 are changed, the characteristics of the LPF can be adjusted against the frequency of a used clock and characteristics of the ICs 108 and 109. Therefore, the signal line driving ICs can be operated with high-speed clocks.

Title: Glass-like carbon electrode plate for plasma etching
Inventor: KOKAJI KAZUMI
IPC: H01L21/302
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To keep a close contact between an electrode plate for plasma etching and a back plate and to make an etching rate uniform at the periphery of the electrode plate and the center thereof by applying a compressive stress to the electrode plate, such that the electrode plate for plasma etching itself warps convexly toward the mounting side thereof as it is consumed by plasma etching. SOLUTION: An electrode plate for plasma etching is shaped like a disc and a compressive stress is applied thereto, such that the electrode plate for plasma etching itself warps convexly toward the mounting side thereof since it is consumed by plasma etching. The compressive stress is applied by a centrifugal forming method, in which a starting material of resin of a liquid state is formed by a centrifugal force into a cylinder of uniform thickness in a cylindrical die. Although the formed resin is cylindrical, when it is cut longitudinally, it becomes a plate in shape because it is soft like rubber. The plate has a hysteresis such that the surface in contact with the die of a centrifugal forming machine is convex because the die of the centrifugal forming machine is curved.  The hysteresis does not disappear during the following processes of curing, carbonizing by calcination, and high-temperature heat treatment.
