Title: Air cleaning device
Inventor: ISHIGAMI MICHIO
IPC: F24F7/06
Filed: 1987-03-25
Abstract: PURPOSE:To enable air circulation and discharging of air to be separately performed by a method wherein an air circulation passage is branched, the air passage is changed over with a damper. CONSTITUTION:Under a condition that a ventilation air passage 4 is closed by a damper 5, air sucked from a suction port 6 is sent to a blowing port 7 through an air circulation passage 1, passed through a filter 3 and then discharged into a room through a blowing port 7. When the damper 5 is opened, the air circulation passage 1 is closed and the suction port 6 facing to the indoor part comes to communicate with an outdoor part through a ventilation passage 4, resulting in that bad odor within the room can be discharged out of a house by a blower 2. If the blower 2 is rotated in an opposite direction, the suction port 6 and the blowing port 7 are made in opposite relation in turn in the case of performing a ventilation operation, the surrounding air can be introduced into the indoor part.

Title: Shaft sealing apparatus
Inventor: MINEYOSHI KIYOHARU
IPC: F16J15/54
Filed: 1980-05-29
Abstract: PURPOSE: To watch wear of the shaft sealing part and permit alarm to go off before the pressure of the sealing oil decreases and hydrogen gas leaks by detecting the increase of the flow rate of the sealing oil sent to the shaft sealing part, in the shaft seal for a hydrogen cooled turbine generator having a large capacity.  
     CONSTITUTION: The hydrogen gas sealed in the equipment of a turbine generator 6 is sealed in the shaft sealing part 5 by the sealing oil supplied from an oil pump 2. Into the oil pump 2, oil is supplied from an oil vessel 1, and the oil amount is controlled to the constant discharged oil pressure by a safety valve 3. When the amount of the oil sealed which flows in the shaft sealing part 5 increases abnormally over the capacity of the oil pump 2, a pressure switch 4 operates, but the pressure for preventing leak of hydrogen gas is hardly maintained. Midway on the piping for feeding sealing oil, a flow meter 7 is fitted, and thus the increase of the flow amount can be detected in early time, and shortage of the sealing pressure as a result of the fact that the oil flow amount increases above the capacity of the pump 2 can be prevented beforehand.

Filed: 1984-04-11
Abstract: PURPOSE:To reduce the discharge of NOX upon starting, by closing shut-off valves in inlet and outlet pipe lines to remote water in an evaporator, then opening a bypass valve to remove steam in a superheater, and by filling dilute ammonia gas to a denitration catalyst (DeNOX). CONSTITUTION:Before starting of a gas turbine, shut-off valves 23, 26 are closed while a blow valve 25 is opened to remove all of water in a preevaporator 10, and a bypass valve 22 is opened while a valve 29 is fully closed to remove steam in a superheater 9. Further, when the gas turbine starts, the amount of heat-exchange between the superheater 9 and the preevaporator 10 is decreased so that exhaust gas from the turbine slightly decreases its temperature and reaches a DeNOX section 11 to maintain the operating temperature Td of the section 11 at a higher value, and therefore, the operating temperature T2 of the DeNOX upon starting is raised to enhance the rate of denitration. Further, dilute ammonia gas is filled after the gas turbine is ignited, to reduce the discharge of NOX.

Abstract: PURPOSE:To keep the titled head at an optimum bias point with less bias current by electrically connecting one-end parts of two shield magnetic bodies and using the other-end parts as a bias current input/output part. CONSTITUTION:One-end parts of the first and the second shield film 9 and 10 on both sides of an MR element 11 are electrically onnected through a connecting conductor film 13 and the other-end parts are used as bias current input/output terminals 15 and 16. When a DC current is impressed between both input/output terminals 15 and 16, a constant-current circuit is formed successively through the input part 15, the shield film 10, the conductor part 13, the shield film 9 and the output part 16, magnetic flux in the Y direction is impressed on the element 11 by the energizing of the shield film 10 and the same magnetic flux is further impressed in the Y direction by the energizing of the shield film 9. Accordingly, a magnetization bias is made possible with about a half current. An increase in the temp. of the peripheral part of the MR element can be thus controlled and the drift of reproduced signals and noises can be reduced.

IPC: B24B53/04
Filed: 1986-03-27
Abstract: PURPOSE:To increase the life of a correcting tool and improve the accuracy of grinding face by gradually cutting a required part repeatedly when a cutting amount is judged to be larger than a prescribed value by a judging part, and forming a tapered grinding face. CONSTITUTION:A specified shape of tapered grinding face Gb1 is assumed based on a cylindrical grinding face Ga1 before correcting, with respect to a grinding wheel shape L before correcting which is stored in a shape memory part 1, and the size of cutting amount A in order to form the assumed grinding face Gb1 is judged by a judging part 2. When this cutting amount is judged to be larger than the prescribed value, the grinding wheel is repeatedly subjected to correcting grinding by degrees, to obtain the tapered grinding face Gb1. After that, the correction finishing of the cylindrical grinding face Ga1 and the tapered grinding face Gb1 is carried out with one continuous process, to form finished faces Ga, Gb. Accordingly, since the cutting amount of a correcting tool D can be made less than a defined value when forming the tapered grinding face Gb, the life of the correcting tool can be increased while improving the accuracy of the grinding face Gb.
