Title: Fluid injection device
Inventor: KAWATANI SEI
IPC: F02M61/16
Filed: 1995-05-31
Abstract: PURPOSE: To eliminate the need for special-purpose cooling fluid feed pumps to improve the injection characteristics by allowing a fluid for cooling a needle valve on suspended nozzle side to leak from the sliding gap between the large diameter part of a needle valve on operating nozzle side and a guide hole and to supply to the outer peripheral surface of the small diameter part of a needle valve on suspended nozzle side. CONSTITUTION: When the engine operates at high speeds, a control device 66 receives a signal output from an engine speed sensor 68 to deenergize a solenoid 62. Thus, since a change-over valve 50 is hept to a right moving position by a return spring 64, a supply passage 58 is connected to the second supply or discharge 56, and the first supply or discharge is also connected to a leak passage 60. Therefore, when a high pressure fuel is supplied to the supply passage 58, the second needle valve 26 is opened in order for the fuel to be injected from the second nozzle 22 having a large total nozzle area. A this time, after a part of the high pressure fuel leaks and flows to a fuel passage 30, the fuel flows through the leak passage 60 and flows to a fuel tank or a low pressure fluid source. Thus, the suspected first needle valve 24 and nozzle body 12 around the needle valve are effective cooled.

Abstract: PURPOSE:To provide a thin-film solar battery with highly radiative characteristics of infrared ray on the rear electrode side. CONSTITUTION:A transparent conductive film (transparent electrode) 2, a semiconductor conjunctive layer 3, and a rear-face electrode 4 are formed on a transparent insulating substrate 1 in a thin-film solar battery cell. An infrared- ray reflective film with reflectance of 5% or above (preferably, 50% or above) for infrared ray of 1mum to 20mum in wavelength (preferably 3mum to 5mum and 8mum to 13mum) is formed on the rear-face electrode 4 side in a spattering step with a target of SiO2. Then, radiation of infrared ray on the rear electrode side can be improved. When there is a defect of short circuit in the thin-film solar battery, the defect can be detected by thermal-image measurement carried out from the rear electrode side, because the in-plane distribution of temperatures formed when a forward current is applied is enough to detect the defective location. As a result, the defect can be detected easily and accurately.
