Abstract: PURPOSE: To prevent ozone harmul to the human body from leaking outside during power failure or emergency stop, by equipping the raw material air pipe of the titled device with a checking device.  
     CONSTITUTION: In an ozonizer wherein an air from the blower 1 is dehumidified by the defumidifier 3 and sent to the ozonizer 11, high voltage is applied from the power device 30 to the discharge electrode 13 of the ozonizer 11 to give ozone, air pipes are equipped with the back flow preventing device 30, e.g., check valve, solenoid valve, etc. and the piping 24 for discharge connected to the ozonizer. The back flow of ozone is prevented by the back flow preventing device 30 during power failure or emergency stop, and ozone is released to a decomposing device by the piping 24 for discharge. Thus the leakage of harmful ozone to outside is prevented, and the oxidation of the dehumidifier, air source device, etc. caused by the back flow of ozone with highly oxidative effect is also prevented.

Abstract: PURPOSE: To improve the efficiency of the decoding process of digital communication by combining a soft symbol unit or a list generation unit or the like to soft output viterbi algorithm and general purpose viterbi algorithm. CONSTITUTION: By using the structure capable of adapting or controlling the length of the list L of columns with the possibility of being transmitted of the soft output viterbi algorithm(SOVA), serial general purpose viterbi algorithm is realized. In the realizing example, by using an absolute difference between the cumulative measured values of paths at the node of a grating, the L pieces of best paths passed through a decoding grating are repeatedly found. In order to calculate the path 'most approximate to the one of a (t+1)-th order' based on the previously found (t) pieces of the best paths, a minimum absolute difference and the value of the cumulative measured values of the best paths are used. The 'soft GVA' receives the list output of the general purpose viterbi algorithm and calculates output symbol reliability measure for respective decoding symbols.

Filed: 1992-01-30
Abstract: PURPOSE:To exactly and speedily confirm the picture direction matching by preventing the mismatching when a mismatching state is confirmed by judging the picture direction matching of the second picture for the picture direction of the stored first picture information. CONSTITUTION:A document is set to a document table in a step S 181, and a document number counter CNT is initialized to zero in a step S 182.

Title: Control system of fuel cell power generating plant
Inventor: NOMURA MASAHIDE
IPC: H01M8/04
Filed: 1982-02-01
Abstract: PURPOSE:To maintain in a given value the hydrogen concentration in a hydrogen gas and the oxygen concentration in an oxygen gas in the outlet of a fuel cell by adjusting the recycle flow rate of the hydrogen gas and the oxygen gas of the fuel cell so that the hydrogen concentration and the oxygen concentration keep a given value. CONSTITUTION:When a cell output increased, the consumption of hydrogen is increased. Hence hydrogen concentration 501 in the cell outlet is decreased, and so as to compensate this decrease a feedback controller 402 opens a valve 204 to recover the hydrogen concentration 501 in the cell outlet. But when the valve 204 is opened, main hydrogen gas pressure 521 is decreased, and the recover of the main hydrogen gas pressure 521 is slow since the response of a fuel reformer is slow. Because when the valve 204 is controlled only by the hydrogen concentration 501, the main hydrogen gas pressure 521 continues to decrease, that is corrected with a main hydrogen gas pressure deviation signal 522.

Title: Dc short-circuit detector for inverter
Inventor: HAYAMIZU KAZUO
IPC: H02M1/00
Filed: 1995-02-02
Abstract: PURPOSE: To suppress the surge voltage at the time of cutting OFF a current by composing a DC short-circuit detecting current transformer of small size and low cost and reducing the wiring inductance of a DC side electrolytic capaci tor circuit in an inverter having a rectifier, an inverter for converting the DC power of the rectifier to AC power and the capacitor connected between positive and negative buses P and N to connect the rectifier to the inverter. CONSTITUTION: A short-circuit current detector in which a current transformer 10, a small-capacity capacitor 11 and a resistor 12 are connected in series is connected in parallel with an electrolytic capacitor 3 to detect the discharge current flowing in the route of A' and B' at the time of DC short-circuit. Since the capacitor 11 has a small capacity and the discharge current is limited by the resistor 12, the transformer 10 may have the small size and the low cost. Since the transformer is not connected in series with the capacitor 3, the wiring inductance of the capacitor circuit is reduced, thereby suppressing its surge voltage.

Abstract: PROBLEM TO BE SOLVED: To accurately sense the insufficiency of a combustion oxygen even if an ambient temperature of a thermocouple is changed by stopping combustion of a burner when an output voltage of a correcting voltage becomes a reference voltage or below decided based on a voltage held at a stable voltage holding means.
