Title: Simple method of calculating system voltage of electric power system
Inventor: ONO AKIRA
IPC: H02J3/00
Filed: 1989-10-18
Abstract: PURPOSE:To calculate a tide with a high accuracy and at a high speed by changing a matrix Y in the disturbance of an electric power system from the matrix Y in the normal electric power system, calculating a generator terminal voltage from the changed matrix Y and calculating a tide between terminals from the generator terminal voltage and a generator injection current. CONSTITUTION:A tide is calculated by a microcomputer as follows: Firstly, the impedance of a load, a generator terminal voltage, a generator injection current and a matrix Y are obtained from the quantities of a system in a normal condition before a system disturbance. Then, the matrix Y is changed according to the contents of the system disturbance. The generator terminal voltage is calculated by using the changed matrix Y. Then, whether a difference between the generator terminal voltages before and after a change is within a permissible error is identified. When the difference is not within the permissible error, the generator injection current is corrected. From the generator terminal voltage and the generator injection current, the other terminal voltages are obtained and a tide between the terminals is calculated.

Title: Manufacture of cathode-ray tube
Inventor: SUZUKI HIDEO
IPC: H01J9/385
Filed: 1985-12-04
Abstract: PURPOSE:To reduce the occurrence of contraction burst during the evacuation of gas, by performing the heating and gas evacuation of a tube while keeping the temperature of at least one of the funnel and panel of the tube lower than that of the frit-sealed portion thereof. CONSTITUTION:A tube 4 is inserted into a cage 5' fitted with a heat blocking plate 8 at the bottom of the cage. The tube and the cage 5' are moved in a prescribed direction in a gas evacuation furnace 6 so that heating and gas evacuation are performed. Since hot air 7 blowing off from the bottom of the furnace 6 does not directly collide against the funnel 2 of the tube 4, the funnel is indirectly heated through the heat blocking plate 8 so that the temperature of the funnel is lower than that of the panel 1 of the tube. As a result, the difference between the inside and outside surface temperatures of the tube 4 is reduced to lower the temperature of the outside surface of the frit-sealed portion 3 thereof. For that reason, the generation of thermal stress is much reduced to greatly decrease the ratio of occurrence of contraction burst of the tube in the gas evacuation furnace 6.

Filed: 1992-10-09
Abstract: PURPOSE:To provide a gas-insulated switchgear in which miniaturization of, and reduction in size of, the entire device is realized by contriving an arrangement between a lightning arrester and other devices. CONSTITUTION:Single-phase bus lines 1 for three phases are made to branch off, in parallel, from a main bus 5, and a circuit breaker 4 is disposed on each single-phase bus line 1. A space is formed between a part of a covered conduit W on a breaker 4 side and a rising portion of the single-phase bus lines 1 bent like a letter U on the breaker 4 side. A lightning arrester 2 is disposed in this space. Specifically, the lightning arrester 2 is disposed below the single-phase bus line 1 in such a way as that the axis of the lightning arrester is in line with the axis of the single-phase bus line 1 when it is horizontally viewed. The lightning arrester 2 is arranged along the axis of each single-phase bus line 1, and does not project sidewards from the single phase bus line 1. Hence, the whole of a gas insulated switching device can be miniaturized and reduced in size by reducing an interval between the single-phase bus lines 1.

IPC: H01L21/3065
Filed: 1986-11-17
Abstract: PURPOSE:To decrease overhang of an insulation layer formed on a first interconnection layer and to prevent short circuit between first and second interconnection layers, by performing both the isotropic and anisotropic etchings for providing the first interconnection layer with blunt edges. CONSTITUTION:An insulation layer 2 and a conducting layer 3B providing a first interconnection layer are formed on the whole surface of a substrate 1. The substrate masked with a mask 6 is subjected to isotropic etching and subsequently to anisotropic ethcing for forming a first interconnection layer 3 having blunt edges 3A. After the mask 6 is removed, an insulation layer 4 is formed thereon. The blunt edges of the first interconnection layer 3 prevent the insulation layer 4 from being overhung in the sections corresponding to the edges 3A. After that, a second interconnection layer 5 is formed on the insulation layer 4. In this manner, the insulation layer 4 can be formed without overhang and, therefore, short circuit between the interconnections 3 and 5 which would be caused if any overhang is present can be prevented effectively.
