Title: Fuel cell power generation plant
Inventor: TANABE SEIICHI
IPC: H01M8/06
Filed: 1983-04-26
Abstract: PURPOSE:To enhance the economical efficiency of a generation plant for a fuel cell by connecting an air separator to at least one of the air electrode and the cooling electrode of the fuel cell. CONSTITUTION:An air separator 10 is connected to at least one of the air electrode 1b and the cooling part of a fuel cell 1. For instance, gas of about 70% hydrogen concentration is sent from a fuel reformer 3 to the fuel electrode 1a of the fuel cell 1. In the fuel electrode 1a, a part of the above gas reacts with air to produce gas of about 30% hydrogen concentration which is then returned to the fuel reformer 3. On the other hand, air from which dust is removed with an air filter 6 and which is compressed with an air compressor 7a is sent into the air electrode 1b of the fuel cell 1. In the air electrode 1b, only oxygen contained in the above air reacts with fuel gas to produce used gas of about 10% oxygen concentration which is then discharged through the outlet of the air electrode 1b. The used air has a temperature of about 200 deg.C and a pressure of about 5kg/cm<2>. It is applied to an air separator 10 through both a heat exchanger 8a and a moisture separator 13.

Title: Delay circuit for ultrasonic wave diagnosing device
Inventor: IIDA TAKETOSHI
IPC: G01S7/523
Filed: 1983-04-28
Abstract: PURPOSE:To shorten the continuous time of a reflecting signal generated by mismatching between delay lines by providing individually buffer amplifiers between LC delay lines consisting of plural stages. CONSTITUTION:N steps of delay lines 6-1-6-N connected between an input terminal IN and an output terminal OUT and the buffer amplifiers A1-An-1 are connected between respective delay lines. In order to reduce the error in delay time, the inputs and outputs of respective buffer amplifiers are set up to the same in phase. To compensate level drop generated by matching respective delay lines, the gain of the amplifiers is made twice. To prevent a reflecting signal generated by an ultrasonic wave echo signal from being mixed with an adjacent delay line, the buffer amplifiers are provided with one-way characteristics. In such a constitution, the continuous time of the reflecting signal generated by mismatching between the delay elements when the ultrasonic wave echo signal is inputted, is shortened.

Title: Pressure chamber type valve
Inventor: HIRAISHI KAZUO
IPC: F16K31/40
Filed: 1999-03-18
Abstract: PROBLEM TO BE SOLVED: To discharge fluid in a pressure chamber by simple operation, to reduce size, and to reduce the number of part items by arranging a functional part for discharging the fluid in the pressure chamber to the secondary side by manual operation in a main valve element. SOLUTION: Since a pilot hole 4a is blocked up by valve seat packing 10, pressure of a pressure chamber 6 commnicated with a primary side passage 1 is kept under primary pressure by a bleeding hole 3b. A diaphragm valve element 5 is pressed to a seat surface 11a of a valve seat part 11 by differental pressure between this pressure chamber 6 and a secondary side passage 7, and the primary side passage 1 and the secondary side passage 7 are cut off to be put in a water stop state. When pulling up a plunger 9 and the valve seat packing 10 by carrying an electric current to a solenoid valve A, the pilot hole 4a is opened, and the pressure chamber 6 and the secondary side passage communicate with each other, so that pressure of the pressure chamber 6 suddenly drops.  Thus, the diaphragm valve element 5 is pushed up in the direction for separating from the seat surface 11a, and the primary side passage 1 and the secondary side passage 7 communicate with each other to deliver water.

Title: Control device for voice of vehicle
Inventor: TERAURA NOBUYUKI
IPC: G10L15/00
Filed: 1988-03-28
Abstract: PURPOSE:To input a voice with less noise and increase the recognition rate of sound by drivingly controlling at least one vehicle loaded equipment to a noise lowering side at the time of detecting the start of the input of voice for controlling various vehicle loaded equipments. CONSTITUTION:When any of switches 19-1 to 19-5 for requiring the input of voice which are installed in a vehicle room is operated, a CPU 17 detects this and outputs a sound cut-off command to a relay circuit 21 to cut off an acoustic signal from an acoustic device 20 to a speaker 22, prohibiting the regeneration of sound. Also, when a noise detected via a microphone 11, band-pass filters 13-1 to 13-5, detectors 14-1 to 14-5, etc., is judged in an improper condition for the input of voice, a whistling sound is issued from the speaker 22. Thereby, the input of voice with less noise can be carried out enabling a high recognition rate of voice to be maintained.

Title: Stabilizing device for amplification degree of photomultiplier tube
Inventor: NAKAMURA MASAO
IPC: G01T1/164
Filed: 1986-03-31
Abstract: PURPOSE:To correct in a short period by controlling the amplification degree of a PMT or corresponding amplifier system based on collected data on each PMT. CONSTITUTION:Photomultiplier tubes 3 generate outputs corresponding to the quantities of light which are amplified and incident after being transduced into electrons. These signals are sent to a position arithmetic circuit 5 to obtain X-directional and Y-directional position signals X and Y. Then they are converted into digital position signals DigX and DigY, which are sent to a position memory 7 and a collection memory 8. Thus, data on the amplification degrees of the respective PMTs 3 are collected in parallel, so the amplification factors of the PMTs 3 or corresponding amplification systems are controlled to stabilize the amplification degrees of the PMTs 3 in a short period.

Title: Liquid fuel combustion device
Inventor: HASHIMOTO AKIRA
IPC: F23D3/40
Filed: 1983-04-26
Abstract: PURPOSE:To provide a smooth ignition condition when starting and reigniting after extinguishing operation and also to contrive to shorten the time required for ignition at starting by a method wherein a heating unit is of a structure having a hollow part and a temperature detecting element is arranged in the hollow part. CONSTITUTION:When a temperature sensing element 9 is directly contacted with a heating unit 5 or is positioned at the end part of the evaporated liquid fuel, it may unpreferably result in producing error between the sensed temperature and the actual quantity of accumulated heat at the evaporation part. The ignition is completed in such a way that after the increased temperature at the evaporation part under an energization of the heating unit 5, the gas is started to flow and is applied igniting operation with an igniter etc. via outlet of the burner. In this case, if the accumulated heat is short, ignition error may occur and in turn if excessive, soot may be produced. Therefore, information on temperature applied by the temperature sensor element 9 is applied for judging the best condition of ignition.
