Title: Water treatment device for fuel cell
Inventor: HORINOUCHI HIROSHI
IPC: H01M8/04
Filed: 1994-06-17
Abstract: PURPOSE:To prevent the blocking of a water treatment device by catching rust, etc., by interposing a filter at the boundary section between a cell cooling- water system and a water treatment system. CONSTITUTION:Rust, etc., in the blow down water B of a cell cooling-water system L1 are caught and removed by the rust, etc., catching filter 20 being interposed between a heat exchanger 7 at the boundary section between a cell cooling-water system L1 and a water treatment system L4 and a water recovery tank 10. At this time, since the filter 20 is provided at the boundary part between the high-pressure cell cooling-water system L1 and the low-pressure water treatment system L4, the pressure difference necessary for filtration can be gotten without dynamic source. Moreover, since the filter 20 is positioned downstream from the heat exchanger 7, the cooling-water is cooled down, and a heat resistance measure for a filter member becomes needless. Hereby, the blocking by the rust, etc., of the water treatment system can be prevented efficiently with simple structure.

IPC: F04F3/00
Filed: 1978-11-06
Abstract: PURPOSE: To obtain a high-head suction device by mounting an air inlet port on a vacuum suction pipe.  
     CONSTITUTION: From driving a vacuum pump 1 with throttle valves 4,4' controlled moderately, a vacuum suction pipe 3 becomes negative in pressure inward to suck muddy water W through a suction fitting 3a and also a moderate air through air inlet pipes 5,5'. And for the first stage, the muddy water W raises a suction pipe 3 about 10 meters from a muddy water surface W' underground. The air sucked through the air inlet pipes 5,5' is then confined in a bent 3c of the suction pipe 3, and there is left a space free from muddy water in said bent 3c. Since the muddy water has a surface tension, an air zone A and muddy water zones B 1 , B 2  are present independently in the suction pipe 3. A head H of a vacuum tank 2 can be sucked H 1  higher than in the case where only the muddy water is full in the suction pipe.

Title: Detecting device of infrared system
Inventor: MURAKAMI TAKAHISA
IPC: G01V8/12
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To avoid interference of signal beams by alternately emitting pulse beams at different timings from a pair of emitting parts, generating synchronous signals from both the signals judged on light receiver side, and independently processing the signals after synchronous wave detection. SOLUTION: Two light emitting parts emit infrared pulse signal beams by pulse signals of mutually different timings generated from a light emitting signal generating part, respectively. Both the signal beams are photoelectrically converted by light receiving parts 11, 21, and amplified by synchronous amplifying parts 12, 22 synchronized to the carrier wave frequencies of both the signal beams, respectively. Synchronous wave detecting parts 13, 23 identify both the signal beams by a signal identifying part 33, and wave-detect them by synchronous signals generated by synchronous signal generating parts 18, 28. Signal wave detecting parts 14, 25 detect only the signal waves transmitted together with the carrier waves.  After further amplification by signal wave amplifying parts 15, 25, whether they are of a prescribed level, or more is judged by comparators 16, 26, and the signals are transmitted to a first judging part 31 and an OR circuit 30 only in the prescribed level or more. According to this method, interference between signals and interference with other infrared pulse beam can be prevented.

Filed: 1983-07-28
Abstract: PURPOSE:To prevent vibration and enhance the energy efficiency by allowing a rotor to rotate on a constant axis statically, permitting vanes to displace in the axial direction of the rotor, and thereby balancing vibrations of the whole device totally. CONSTITUTION:If a pulley 11 rotates a rotor 3' round a rotary shaft 10 in the rear casing 2' at a certain specific speed, vanes 5' make a rotational motion with respect to the inside conical surface 13 of front casing 2'' as well as the rotor 3' a slide revolving motion with respect to a groove 4', and these actions allows suction of the specified fluid through a suction port 7 and discharge of the compressed fluid through a discharge port 8 to form a cycle of operation, which shall be then repeated. At this time friction is made only by vanes 5' in sliding revolutions in the axial direction with respect to the groove 4' of the rotor 3', and the effects are cancelled by one another because all motions are made spot symmetrically about the center 17 of the facade 9 of the rotor 3', so that the whole construction is held well balanced. Accordingly no significant vibration will be generated with noise also well suppressed, which may lead to provision of possibility of saving the energy.
