Patent JP-H0333404-A (JP)
Title: Steam valve with variable operating force
Inventor: JIEEMUSU MAATEIN SUDORUNIKU
IPC: F01D17/10
Filed: 1990-04-20
Abstract: PURPOSE: To reduce valve actuating force past a cracking position by forming two types of effective diameters of a balance cylinder and a balance piston, respectively. CONSTITUTION: In this steam valve 56, two types of effective diameters are formed out of an inner-periphery surface 62 and an inward flange 72 at a balance cylinder 64, and two types of effective diameters are formed out of a larger diameter outer-periphery part 68 and a smaller diameter outer-periphery part 70 at the sleeve 66 of a balance piston 58. When a main valve 12 and the balance piston 58 move upward past a cracking position, the smaller diameter outer-periphery part 70 faces the inward flange 72, and a sealing flange 60 faces the inner-periphery surface 62. As a result, steam can pass through without the inward flange 72 being restrained, the differential pressure which supports upward balance force acts on the whole relatively wide area determined by the sealing flange 60.  It is thus possible to exert larger balance force by a steam valve 56 past the cracking position, thereby reducing valve actuating force.

Title: Method and device for regulating control pressure of pressure control valve
IPC: F16K17/06
Filed: 1992-03-30
Abstract: PURPOSE:To adjust a control pressure by using air without using fuel. CONSTITUTION:A method is for adjusting a control pressure of a pressure control valve 10 divided into a control valve chamber 16 and an atmospheric chamber 20 by a diaphragm 12 and formed with a fuel introducing path 14 and a fuel discharge path 15 in the control valve chamber 16 to mount a valve unit 13 to the fuel discharge path 15 and a spring 25 into the atmospheric chamber 20.

Title: Safety device for gas combustion apparatus
Inventor: SHIMODAIRA TATSUROU
IPC: F23N5/10
Filed: 1978-08-24
Abstract: PURPOSE:To prevent abnormality such as extinguishments by blows from two burners with a single gas safety device through series connection of two thermocouples and one gas safety valve and parallel connection of two switch units and an electric resistor. CONSTITUTION:A gas safety valve 2 is connected in series to thermocouples 25 and 26. Switches 27 and 28 are opened respectively by a cam unit 15 or 16 with the opening action of a gas opening/closing valve 3 or 4. For  example, when only the  left burner is put into action, a control knob 9 is turned up to 90 deg.. The gas safety  valve 2 and the gas opening/closing valve 3 are opened, and the burner is ignited  and the thermocouple 25 is heated to generate a thermal electromotive force V  whereby the gas safety valve is sucked. With the control knob further turned to  180 deg.C, a shaft 19 is returned to the position of closing the gas safety valve 2, but  the valve remains open. Thus, the combustion continues. At this point, if the flame  is put out by a blow, the electromotive force V varnishes and the safety valve 2 is  closed to cut the gas.

Abstract: PURPOSE:To absorb timewise and spatial distortion by correcting the optimum operating point of an image coder based on a calculated coding rate so as to obtain an optimum balance in the visual characteristic. CONSTITUTION:A coding control section 210 calculates a generated code quantity R(q) and an S/N D(q) to calculate a coding rate Ss(q)=L/(R(q)+ LXPXTn-bn), where q is quantization accuracy. In this case, the control section 210 receives a transmittal confirmation bit number bn from a transmission control section 5 in the transmission state of a preceding coding frame and uses the S/N D(q) and the coding rate Ss(q) to calculate an image quality trade-off function Ss=G(Ds). Then the control section 210 calculates q, Ss(q) being cross points between the function Ss and an object function So=O(Do), starts a quantization section 223 to quantize an image signal by one frame. Then the control section 210 starts 1st and 2nd variable length coding sections 224, 225 to code quantized image data and calculates a frame jump time Tn up to a succeeding coded frame depending on the coding rate Ss and restore to the original operation.

Filed: 1980-07-30
Abstract: PURPOSE:To reduce the installation space of a device by a structure wherein an insulative case having a piezoelectric element inserted therethrough is adapted to slide quickly in the axial direction. CONSTITUTION:The insulative case 27 is fitted slidably which has the piezoelectric elements 28, 28 inserted therethrough through an insulative case holder 12 having a V-shaped cross section to fit to a metal support plate 1 and a terminal plate 29. The insulative case 27 has a pressurizer 30 opposed to a colliding projection 3 of the support plate 1 and exposed partially outside the case body, and a stator 31 on the opposite side to the pressurizer 30 and in contact with a regenerative spring 37. When an operating shaft 41 is rotated in the counterclockwise direction from a nonfiring position, a pawl projection 43 pushes the insulative case 27 to slide rightwardly contracting the spring resiliently. When the spring reaches its contraction limit, the pawl projection 43 drops from the pressurizer 30, so that the case 27 slides rapidly in the leftward direction to bring the pressurizer 30 into collision with the colliding projection 3. Then, the piezoelectric elements 28 output a high voltage by which the gas is fired.
