Title: Pllot type pressure regulating valve
Inventor: HIEI SHIYOUKI
IPC: G05D16/06
Filed: 1981-04-30
Abstract: PURPOSE:To extremely reduce the difference between the pilot pressure and the secondary pressure, by installing a diaphragm which acts to correct the force of the valve spring. CONSTITUTION:The force which a diaphragm 1 or 2 of a pilot type pressure regulating valve 30 receives from the pilot pressure or the secondary pressure is determined not only by the area of the diaphragm but also by the contact areas between diaphragms 1 and 2 and a holder 8 and distance shown as r1 and r2 from the margin of the holder 8 to the diaphragm fitting section. Moreover, the displacement amount of the diaphragms 1 and 2 is determined by the force which the diaphragms 1 and 2 receive from the pilot and secondary forces, the force of a valve spring 9, and the elastic modulus of the matrial of diaphragms 1 and 2, etc. Therefore, by appropriately determining an effective pressure receiving area of the diaphragm, upon which the pilot pressure is applied, and another effective pressure receiving area of the diaphragm, upon which the secondary pressure is applied, the difference between the pilot pressure and the secondary pressure can be minimized extremely.

IPC: F02B31/00
Filed: 1979-05-30
Abstract: PURPOSE: To maintain a pressure difference always at constant between places before and after the second throttle valve and obtain a high charging efficiency even when an engine is in a state of high speed and large load operation, by opening said throttle valve for said pressure difference becoming at least a prescribed value.  
     CONSTITUTION: A negative pressure is generated in an intake manifold 10 at the downstream from a throttle valve 12 of a carburetor and applied to a high pressure chamber 28 of a negative pressure control valve 23 through a conduction pipe 42. In a common link path 43 linked to an intake port 5d at the downstream from the second throttle valve 14, a negative pressure larger than that at the upstream side is produced and applied to a low pressure chamber 27 of the valve 23 through a conduction pipe 45. When a difference between the above said both negative pressures comes to be at least a prescribed value, a disphragm 26 is moved against the tension of a spring 33 to permit a valve unit 37 to close a link hole 39 simultaneously open an atmospheric hole 36. Consequently, the atmospheric air flows into a negative pressure chamber 20 of a throttle valve actuator 17 to rotate the second throttle valve 14 in the direction of an arrow mark A.

Abstract: PURPOSE:To afford an after-burning function to a compact boiler body and to make it possible to prevent the same from freezing by providing a circulation pump at one end of a heat exchanger for use in a bath. CONSTITUTION:At the time of the after-burning of a bath, a heat exchanger 2 is heated by a heating unit 3 to drive a circulation pump 7 whereby water within a heat exchanger 9 for a bath contained in a communication pipe 6 is heated, and is introduced into a bathtub 11 via a circulation pump 10. In a case where a hot water feed quantity is small, the heating unit 3 is turned ON or OFF via a hot water temperature detector 12. In accordance with this, the feed hot water temperature is varied. However, since a capacity exists in the communication pipe 6, a comfortable hot water feed temperature can be obtained. Further, in the winter season, in a case where there is a possibility of freezing, the set temperature of the hot water temperature detector 12 is made low and the heating unit 3 is burnt, and the circulation pump 7 is driven, whereby the inside of the heat exchanger 2 is uniformly heated, and the freeze prevention becomes possible.

Title: Position detector
Inventor: HASHIMOTO KOICHI
IPC: A61H7/00
Filed: 1986-03-25
Abstract: PURPOSE:To automatically adjust the corresponding relation between the position of moving matter and a detection member, by providing a pair of switching means detecting the position of a position detection part to control a drive part and a stopper for limiting the moving quantity of the position detection member. CONSTITUTION:When moving matter 1 is moved by operating a motor and rotating a drive shaft 3 and present at an intermediate position, a follower gear 14 is meshed with a gear 21 and a position detection member 15 is moved. When the matter 1 reaches moving upper and lower ends, stoppers 26, 27 prevent the movement of the member 15 and switching means S1, S2 detects upper and lower end positions to reverse the rotation of the motor. By this mechanism, the matter 1 moves downwardly and upwardly. For example, when the matter 1 is positioned at the moving lower end and large external force is applied to a push-down direction, the matter 1 exceeds the lower end but the member 15 can not move and, when the external force is removed, position detection parts 16, 17 show the lower end positions to reverse the rotation of the motor and the matter 1 is moved upwardly. The same operation is performed when the matter 1 is positioned at the moving upper end and the shift of the moving range of the matter 1 can be reduced.
