Title: Radiation thermometer
Inventor: SAKUMA WATARU
IPC: G01J5/02
Filed: 1985-09-04
Abstract: PURPOSE:To enable the measurement of the temperature of a fine object to be measured, by providing apertures each with a mirror face on the side of the object at an opening arranged in the object side front center of an infrared detection element to remove infrared rays resulting from a disturbance by things other than the object being measured. CONSTITUTION:A first filter 2 is inserted into a tip opening of a detection head 1 and a lens 3 is fitted into the inside thereof. Then, a box body 8 in which an aperture 80 is fitted into the front opening thereof while a case 4 provided inside through a heat insulating material 9 is projected at the rear end of the detection head 1, apertures 41 and 42 and a second filter 5 are arranged at the opening thereof while the front faces of the apertures 41 and 42 are formed as mirror surface. Infrared rays resulting from a disturbance by things other than a fine object to be measured are removed gradually with the apertures 80, 41 and 42 and hence, the temperature of the apertures 41 and 42 will not rise when infrared rays only from the object being measured reach a thermal type infrared rays detection element 6. This prevents a possible temperature difference between the second filter 5 and the detection element 6, thereby enabling accurate measurement of the temperature of the fine object being measured.

Title: Gas supply device for pressure phosphoric acid fuel cell
Inventor: GOTO HEISHIRO
IPC: H01M8/04
Filed: 1990-07-25
Abstract: PURPOSE:To reduce variation in gas pressure and suppress over-differential pressure and hence to stabilize pressure by providing a fuel buffering thin film for equally partitioning a fuel supply manifold into a fuel inlet side and a fuel electrode side, and an air buffering thin film for equally partitioning an air supply manifold into an air inlet side and an air electrode side. CONSTITUTION:When there occurs instantly over-pressure rising within a fuel cell, a fuel buffering thin film 7 turn to a position 7b, which increases the volume of the electrode communicating zone for gas to communicate to the fuel cell thus suppressing the pressure rising. Meanwhile, when there occurs instantly over-pressure drop within the fuel cell, the thin film 7 is turned in a position 7a, which decreases the volume of the electrode communicating zone thus buffering the pressure drop of the fuel. Likely, when there occurs over-pressure rising within an air electrode, an air buffering thin film 8 is turned in a position 8b, which increases the volume of an electrode communicating zone for air communicated with the air electrode thus suppressing the pressure rising of air. Meanwhile, when there occurs instantly over-pressure drop within the air electrode, the thin film 8 is turned in a position 8a, which decreases the volume of the electrode communicating zone thus buffering the pressure drop of air.

Title: Burning control circuit
Inventor: MATSUDA AKIRA
IPC: F23N5/24
Filed: 1984-09-20
Abstract: PURPOSE:To improve the stability and to reduce the cost by causing a high voltage charged in a condenser to solenoid valve and holding the valve in an open position by flowing a low current to the solenoid valve through a resistor thereafter. CONSTITUTION:The voltage which is charged to a condenser 5 from a commercial power source voltage section through a rectifier 3 and a resistor 4 is allowed to flow through a solenoid valve 6 when a transistor 7 is turned on. Therefore, the solenoid valve 6 is instantly applied with a voltage to be opened to allow the gas to flow to the burner, which is ignited by a spark. Thereafter, a low voltage is applied to the solenoid valve 6 through the resistor 4 to hold the solenoid in an open position for sustained burning. The burning is monitored by a flame rod 14, and if the flame is extinguished due to a wind etc., a microcomputer detects it and the output (a) is stopped. Then, the transistor 7 is turned off to block the circuit, and the solenoid valve 6 is closed to prevent the raw fuel gas from leaking. Therefore, fire hazard, gas explosion or gas poisoning can be prevented.
