Patent JP-S63137183-A (JP)
Title: Fine working method
Inventor: SEKINE YASUHIRO
IPC: C23F4/00
Filed: 1986-11-29
Abstract: PURPOSE:To permit fine working to a smooth sectional shape with high dimensional accuracy, by using carbon alone or materials contg. carbon atoms as a material for an etching electrode. CONSTITUTION:The material contg. the carbon alone or the materials such as polyester resin and polycarbonate resin contg. the many carbon atoms are used as the etching electrode at the time of subjecting multi-layered films alternately laminated with TiO2 and SiO2 to reactive ion etching. The shape of the etching section is smoothed and the pattern exchange difference between a resist mask and etching pattern is entirely eliminated by this method. The taper angle at the lateral section of the etching pattern of the multi-layered films is controllable by using an etching gas consisting of a halogen substituted product of hydrocarbon such as CF2Cl2 and incorporating an oxidizing gas or reducing gas therewith.

Title: Driving of fluorescent indicator tube
Inventor: SEO KOKICHI
IPC: G09G3/12
Filed: 1987-11-10
Abstract: PURPOSE: To prolong the service life by detecting the change of the anode current and controlling the cathode voltage so that the anode current may be kept at a prescribed vale. CONSTITUTION: A driving voltage is given to anodes P1 to Pn of individual display segments of a fluorescent display tube 1 from a driver 4, to which a data input signal is inputted through a decoder 5, to make them emit light. An anode current detection part 2 always monitors the change of anode currents of segments and detects their variation to control a cathode power source 6 by an anode current control part 3 so that anode currents are kept constant. Thus, the degradation in emission capability of an oxide cathode, which is caused by sulfur generated by a decomposition phenomenon of phosphors during the operation of the fluorescent display tube, is automatically restored to extend the life.
