Patent JP-S6412426-A (JP)
Title: Manufacture of ceramic-based superconducting wire
Inventor: KASAHARA TOSHIO
IPC: B28B1/00
Filed: 1987-07-06
Abstract: PURPOSE:To manufacture a superconducting wire having a high current density and capable of being made into a fine wire by making a material which is to become a ceramic superconductor by oxidation into a wire material, covering it with a noble metal, and then heat-treating it in an oxidizing atmosphere. CONSTITUTION:An alloy YBa2Cu3 is melted and cast into a rod shape. The rod undergoes a swaging, rolling and wire-drawing processes to be manufactured into a fine wire. The fine wire is then silver-plated and heated at a temperature below the melting point of the silver in an oxidizing atmosphere. While the YBa2Cu3 alloy is oxidized to become a ceramic superconductor through the heat treatment, the presence of the silver restricts the supply of oxygen and prevents the superconductor from becoming powder or from being burned to form crystals of fine perovskite. Further pressurizing an expansion pressure during oxidation by the creep of the silver, growth of the ceramic is accelerated under a high pressure. In this way it is possible to manufacture a superconductive wire having a higher current density and capable of being wire-drawn to a fine wire.

Abstract: PROBLEM TO BE SOLVED: To rapidly and precisely measure and monitor the concentration of available constituent of circulating water by measuring the concentration of a polycarboxylic acid or the like as a water treating agent by a chemiluminescence method after pre-oxidizing the sample of circulating water. SOLUTION: An electrolytic oxidation device is used for a reagent oxidation reactor 4 which oxidizes a detecting reagent such as a ruthenium complex or the like.

Title: Fuel control device for engine
Inventor: NAGATA TETSUJI
IPC: F02D41/04
Filed: 1988-07-05
Abstract: PURPOSE:To make it possible to exactly compensate for intake-air detection error in accordance with engine temperature by varying moderate correction factor so that the corrected value becomes smaller when the engine temperature is low. CONSTITUTION:Based on output value from a water temperature sensor 14 a control unit 11 makes a correction of water temperature to compensate for the fuel supply quantity in accordance with reduction in water temperature. The fuel injection quantity is calculated by applying a moderate correction employing weighted mean based on the fundamental fuel injection quantities calculated previously and now from intake-air quantity and engine speed. The moderate correction factor used for the calculation is reduced proportional to the water temperature during the deceleration of the engine. The corrected fuel injection quantity is brought close to the not yet corrected fundamental fuel injection quantity. Detection error due to inertia of an air flowmeter during the deceleration of the engine 1 can thus be exactly compensated in accordance with the water temperature of the engine.

Title: Ic tester
Inventor: NAKAMURA HIROTO
IPC: G01R31/26
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To block positional shift of a supporting frame through a simple structure in which a protrusion located substantially in the center of each side of the supporting frame is provided with a groove extending in parallel with the central axis of each side and the groove is engaged with a fixing pin on a board of substantially same width as the groove or slightly thinner than the groove. SOLUTION: A protrusion 124 is provided in the center of each side of a supporting frame 110 and a groove (or an elongated hole) 125 is made in parallel with axes X and Y from the forward end of the protrusion 124. The groove 125 is then engaged with a fixing pun 126 planted on a board 111. According to the structure, thermal elongation of the supporting frame 110 can be absorbed in the longitudinal direction of the groove 125. Furthermore, since the engagement of the groove 125 and the fixing pin 126 is free in the longitudinal direction of the groove 125 (X, Y axis directions) but limited in the breadthwise direction (orthogonal to the X, Y axis directions), the central position of the supporting frame 110 can be kept accurately.  Consequently, horizontal shaking is eliminated with respect to the board 110 and the contact position is kept correctly between the pin of the IC and the IC socket.

Title: Razor
Inventor: YUDA AKITO
IPC: B26B21/56
Filed: 1997-06-11
Abstract: PROBLEM TO BE SOLVED: To facilitate shaving at fine portions such as the armpit by providing a guard for fixing a blade to the body of a razor and the blade which is shorter than the guard and fixed so that it cantilevers at one end of the guard when viewed in its long axis. SOLUTION: A razor body 1 has a guard 2 designed to fix a blade 3 and a handle 4 connected to the guard. If a long blade is used to shave armpit or eyebrow hairs, the razor can have an unnecessary portion for shaving and has a detrimental effect. Therefore, the length of the blade 3 is set to about half the conventional one for facilitating shaving of armpit hairs, for instance. The absence of blade at a portion of the guard 2 allows the portion to be applied to the skin and prevents the force to be concentrated on the blade 3, avoiding the occurrence of razor rash.
