Title: Fault point locating method for n-terminal parallel two-line power transmission line
Inventor: MURATA KENJI
IPC: G01R31/08
Filed: 1990-05-31
Abstract: PURPOSE:To find the distance from a terminal to a fault point and to accurately locate the short-circuit fault point by performing equivalent conversion to a T type three-terminal parallel two-line power transmission line circuit which has three branches on the basis of one of branch points of a power transmission line. CONSTITUTION:A CPU 16 converts an inverted L type difference current circuit which includes power receiving terminals 4 and 3 and a branch point b3 into a linear equivalent circuit which has a virtual power receiving terminal to generate a T type equivalent circuit which has a power transmission terminals 1 and power receiving terminals 2 and 3. Then the fault distance (x) from the power transmission terminal 1 is calculated; when x <=l1 (l1: distance between power transmission terminal 1 and branch point b2), it is considered that the fault point is between the power transmission terminal 1 and branch point b2 and this (x) is regarded as the distance from the power transmission terminal 1 to the fault point. Similarly, the fault distance where the virtual power receiving terminal is viewed from the power receiving terminal 2 and then from the virtual power receiving terminal respectably is found, the circuit is converted into the type equivalent circuit of the power receiving terminals 3 and 4 and virtual power receiving terminal on the basis of the branch point b3, and decisions are made at the power receiving terminals 4 and 3 successively and similarly. Thus, the short-circuit fault point can accurately be located according to current information on each terminal.

Abstract: PURPOSE:To reduce the generation of off-track, and to improve mass productivity, by molding a glass, etc., at a groove working part formed obliquely at a sliding plane with which the medium plane of each core of a R/W core, a center core, and an E core brings into contact. CONSTITUTION:High saturation magnetic flux density materials 71-74 are formed at the opposing plane of a R/W core 1, and a center core 13, and furthermore, a non-magnetic material is formed at the gap forming plane of each core of the R/W core 11, the center core 13, and an E core 12. After those cores are welded in one body by a welding glass, etc., the groove wording part is formed obliquely at the sliding plane making in contact with the medium of each core, and the glass, etc., is molded on those groove working parts 81-84. For this reason, recording can be performed sufficiently on the medium with a high magnetic holding force, and the generation of the off-track can be reduced, and the working frequency of a narrow track groove can be reduced, and furthermore, it is possible to obtain a composite magnetic head with high performance and adaptive for mass production.

Filed: 1983-08-06
Abstract: PURPOSE:To obtain a Schottly junction structure FET having characteristics of which leakage currents among source and drain electrodes for the FET and a substrate are slight and stable by forming the source and drain electrodes by a high melting-point metallic oxide. CONSTITUTION:A field oxide film 22 and a gate oxide film 23 are formed to an Si substrate 21, and a gate electrode 24 is formed. An insulating film 25 is shaped to the electrode 24 and the surface of the substrate 21. Source and drain forming regions and the upper surface section of the electrode 24 are removed selectively while leaving the side surface section of the electrode 24 of the film 25. A film 26 consisting of a high melting-point metallic nitride is formed on the whole surface. The thickness of the film 26 on the film 25 of the side surface of the electrode 24 is made thinner than that on the main surface of the substrate 21. The film 26 is patterned to form a source electrode and a drain electrode 28. Each electrode pattern is terminated on the film 25 of the side surface of the electrode 24 on the patterning. The whole is thermally treated at a temperature, preferably, a temperature of 700 deg.C or higher. Accordingly, leakage currents among the electrodes 27, 28 and the substrate 21 are reduced largely.

Filed: 1980-10-14
Abstract: PURPOSE: To prevent the drop of bricks during tilting of a pan as far as possible while assuring the effective volume for the volume of the pan sufficiently by specifying the brick holding mechanism of a metallurgical vessel.  
     CONSTITUTION: The slag lined wear bricks 4i in the uppermost stage of the metallurgical vessel form tapered surfaces (b) inclining toward upward and the inner side of a furnace on their outside circumferential surfaces. On the other hand, monolithic refractories (high alumina castable refractories are conceivable as material) 6 are applied between the bricks 4i and a shell 1, and this results in that they have tapered surfaces (c) engaging tightly with the surfaces (b). The movement in the axial line direction of the bricks 4aW4i are thoroughly prevented by the engagement of the surfaces (b), (c). Refractory mounting the reinforcing pieces 7 are mounted at required circumferential pitches slightly downward from the top end of the shell 1, and as these extend into the refractories 6, the refractories 6 are mounted  firmly to the shell 1. Here, the refractories 6 have covering parts 8 extending in the  furnace inside direction, and when these peel, they are easily repaired.

Title: Spacer for liquid crystal display element and liquid crystal display element using this spacer and its production
Inventor: YAMADA TOICHI
IPC: G02F1/1337
Filed: 1992-06-04
Abstract: PURPOSE:To provide the spacers for the liquid crystal display element which eliminate the abnormal orientation of a liquid crystal at the boundaries between the liquid crystal and the spacers and can prevent the movement of the spacers, a liquid crystal display element using this spacer and its production method. CONSTITUTION:The spacers are obtd. by forming coating layers consisting of the intermediate of polyimide on the surfaces of particulates. These coating layers cause an imidization reaction to form the films of polyimide in a thermocompression treatment stage after the spacers are sprayed on the substrates. As a result, the polyimide layers formed on the spacer surfaces accelerate perpendicular orientation and eliminate the abnormal orientation (annular eclipse) generated at the boundaries between the spacers and the liquid crystal. Further, the spacers are securely adhered to the substrates to prevent the transfer of the spacers at the time when the intermediate of the polyimide is imidized.

Title: Access system for control memory device
Inventor: MATSUDA SUSUMU
IPC: G06F9/34
Filed: 1979-11-08
Abstract: PURPOSE: To realize an alteration or extension of the contents of a control unit without giving any operation to the region where a writing is being given to the control unit, by giving an access to the extended part of the control unit based on the alteration/extension address information.  
     CONSTITUTION: In case an optional address is set to the address register 3, the alteration/extension address information read out of the index memory device 2 is selected by the selector 8 in response to the selection control signal SEL to be held at the register 3. At the same time, the selector 6 ignores the read output of the base part 1a of the control unit 1 in response to the signal SEL in case the alteration/ extension address information is read, and delivers the ineffective step. As a result, an access is given to the extended part 1b based on the alteration/extension address information. Thus an alteration or extension of the contents is possible for the unit 1 without giving any operation to the region 1a where a writing is already given in the unit 1.
