Title: Grinding wheel and manufacture thereof
Inventor: TOGE NAOKI
IPC: B24D3/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To obtain long-term stable cutting quality through the excellent supply of a polishing solution and discharge of chips while obtaining the holding force and necessary protruding height of abrasive grains by setting wax material thickness to be specific times as large as an abrasive grain diameter, and forming a chip pocket with base metal matrix exposed with a width specific times as large as the abrasive grain diameter between the abrasive grains. SOLUTION: In arranging abrasive grains 2 in one layer on a base metal 2 for brazing, the abrasive grains 2 are held with a wax material thickness W of about 1/3-1/2 times as large as an abrasive grain diameter(d),and a chip pocket T with the matrix of the base metal 1 exposed with a width about 2/3-2.5 times as large as the abrasive grain diameter(d) between the adjacent abrasive grains 2 is regularly formed. Such a wax material thickness W can ensure the protruding height of the abrasive grains 2 required to exhibit excellent cutting quality while ensuring the holding force of the abrasive grains 2, and the regular formation of the chip pocket T with the exposed matrix of the base metal 1 permits the uniform distribution of the abrasive grains 2 and excellent supply of a polishing solution and discharge of chips.

Abstract: PURPOSE:To permit a simple, quick and exact measurement of copper concn, and zinc concn. by using a standard soln. consisting of copper cyanide, zinc cyanide, sodium cyanie, sodium cyanide, sodium carbonate, Rochelle salt and water. CONSTITUTION:The standard soln. having respectively 0.5, 1.0, 2.0mg/l copper concn. and zinc concn. is prepd. by diluting the composite standard soln. consisting of 1,000mg/l copper cyanide, 1,000mg/l zinc cyanide, 2,000mg/l sodium cyanide, 800mg/l sodium carbonate, and 800mg/l Rochelle salt with pure water. A brass colored brass plating liquid which is a sample is diluted with the pure water to attain the concn. range of said standard soln. and thereafter, the copper concn. and zinc concn. in the brass colored brass plating liquid are measured by an atomic absorption calibration curve method using the standard soln.

Title: Optical logic circuit
Inventor: ODAGIRI YUICHI
IPC: H03K19/14
Filed: 1984-07-20
Abstract: PURPOSE:To enable integration of an optical ligic circuit, by forming a plurality of phototransistors on a semiconductor laser in an integrated manner, and electrically isolating the phototransistors from each other. CONSTITUTION:Two phototransistors Tr 2 are formed on a semiconductor laser 1 in series in the direction of the resonator axis. Thereafter, a groove 116 is provided in such a manner as to cut the resonator axis for the purpose of increasing the electrical resistance between the two phototransistors Tr 2. Thus, the phototransistors Tr 2 can be substantially isolated electrically from each other. When signal beam 200 are simultaneously injected into the phototransistors Tr 2, the laser 1 is allowed to oscillate. When either one of the beam 200 is absent, no oscillation occurs. In this way, it is possible to form an optical integrated AND circuit which operates at low power consumption. An OR circuit can also be formed by changing the size of the beam 200 in this optical logic circuit. When the width of the groove 116 is enlarged, the optical output-electric current characteristics or the like of the laser 1 have hysteresis. Therefore, the optical logic circuit can operate as a memory circuit.

IPC: H04M3/12
Filed: 1983-08-18
Abstract: PURPOSE:To prevent temperature rise in an exchange without a large sized device and increase of the cost by stopping a current supply to a line circuit of a prescribed condition when the temperature of the exchange reaches a prescribed value.
