Abstract: PURPOSE:To lower the resistance of address wiring electrodes and auxiliary capacitance wiring electrodes by forming both electrodes into laminated structure composed of first and second metallic layers and setting the width of the first metal in a direction parallel with the data wiring electrodes larger than the width of the second metal. CONSTITUTION:For example, Al is formed as the first metal at 100nm thickness and an alloy layer composed of Mo and Ta is formed as the second metal laminated on the first metal at 200nm film thickness in the constitution of the address wiring electrodes 12 and the auxiliary capacitance wiring electrodes 13. The alloy layer composed of the Mo and the Ta and the Al layer are continuously etched to obtain th taper shape of an acute angle formed by the flank in the thickness direction of the wiring electrode and the substrate. The width of the pattern of Al in this tapered shape is lager than the pattern width of the alloy layer composed of the Mo and the Ta and the difference between them is within 1mum. Namely, the wiring width of the Al is made larger than in the conventional structure in which the allow layer composed of the Mo and the Ta completely covers the Al layer. The wiring resistance is thus lowered.

Title: Production of oxidation resistant graphite molding
Inventor: YAMAMOTO HIROSHI
IPC: C04B35/52
Filed: 1979-05-28
Abstract: PURPOSE: To mass-produce easily and surely graphite moldings with superior oxidation resistance by mixing boric acid into graphite interlaminar compound particles after which the mixed material is expanded by heating at a specified temp. and press-molded.

Filed: 1989-03-17
Abstract: PURPOSE:To use the heat emission of a magnetic substance effectively by making the inside diameter of a magnetic substance ring composed of bisected bodies greater than the cable diameter with an elastic spacer inserted between them. CONSTITUTION:A magnetic substance ring 1 is composed of bisected bodies 11 and 12, which are assembled into the ring 1 by coupling them with a coupling section 1a. The inside diameter of the ring 1 is constituted greater than the outside diameter of a cable 10. A spacer 2 composed of an elastic body is interposed between the outside circumference of the cable 10 and the inner surface of the ring 1. Thus, no contact with the coupling section 1a will be insufficient by the variation of the outside diameter of the cable 10 due to the allowance. There is no fear that the heat emitted from the ring 1 is taken to the cable 10 because the ring 1 does not stick to the cable 10.

Abstract: PURPOSE:To provide an exciting current controller of a generator for a vehicle in which a decrease in a rotating speed of an engine can be suppressed immediately after an electric load is applied while avoiding an increase in load of a battery as much as possible. CONSTITUTION:An exciting current controller 1 controls an exciting current of a generator 2 for a vehicle to be supplied to an electric load 5 and a battery 3.
