Title: Gas device
Inventor: MIYAZAKI NORIO
IPC: F23N5/24
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption upon ignition and hence prevent voltage of a power supply comprising a dry cell from being instantaneously lowered by manually opening an opening/closing valve interlocking with manual valve opening operation for a safety valve. SOLUTION: Once an ignition button 9 is depressed, a control part 5 detects that the ignition button 9 is depressed, and actuates a high tension generator circuit 7 to start spark discharge. In contrast, as the ignition button 9 is pushed in, a rod 91 pushes a safety valve 3 to open the same. Hereby, gas supply to a burner 11 through a gas supply path 2 is started. Then, when the control part 5 detects the ignition on the basis of thermoelectromotive force from a thermocouple 51, a holding current is forced to flow through a magnet of the safety valve 3, and the magnet attracts and holds an attraction piece whereby a valve opening state of the safety valve 3 is continued even when the push operation for the ignition button 9 is released.  Hereby, power consumption upon ignition is reduced, and voltage of a power supply 6 comprising a dry cell is prevented from being instantaneously lowered.

Title: Stainproof luminaire
Inventor: TAKAHAMA KOICHI
IPC: B01J35/02
Filed: 1996-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire hardly stained by forming a photocatalyst such as a titanium oxide film on the surface of the luminaire such as a reflector. SOLUTION: A titanium oxide film is formed on the surface of a luminaire by a sol-gel method, a metal fog method, a dip method, a liquid phase deposition method, a vacuum deposition method, a sputtering method, or a CVD method, for example. The thickness of the titanium oxide film is preferably set to 100nm-2μm. When the thickness is smaller than this range, the photocatalyst activity is lowered, and the cleaning of the stains stuck to the luminaire becomes difficult. When the thickness exceeds this range, the cleaning level of the stains stuck on the luminaire tends to become the saturated state. When a photocatalyst such as the titanium oxide film is formed on the surface of the luminaire such as a reflector by the liquid phase deposition method, for example, the luminaire can be made hardly stained.

Title: Supplementarily charging method for secondary battery
Inventor: ONODERA TETSUO
IPC: H01M10/44
Filed: 1989-01-10
Abstract: PURPOSE:To supplementarily charge while waiting, prevent the discharge of a battery during transmission, and simplify a charging circuit by providing the charging circuit with multiple charging current states and switching the charging current of the charging circuit via the control signal in response to the load state other than the charging circuit. CONSTITUTION:When a radio transceiver 4 is in the waiting state, a battery is charged at a current i1-i3 which is the difference between the charging current i1 and the waiting current i3. Since the waiting current i is a sufficiently small current as compared with the battery capacity and the charging current i1 is also a sufficiently small current value as compared with the battery capacity, a simple charging circuit like a trickle charge can be used. When the transceiver 4 is in the transmitting state, the transmission control signal 5 existing in the transceiver 4 is inputted to a charging circuit 2, thereby a transistor Tr1 is turned ON and a transistor Tr2 is turned ON, thus a charging current i2 larger than that in the second circuit is fed. Since this charging current i2 is set to the value nearly equal to the current at the time of transmission, no discharge is performed from the battery 3.

Title: Method and device for sound reproduction
Inventor: SUZUKI TAKUJI
IPC: G10L21/04
Filed: 1981-01-14
Abstract: PURPOSE:To decrease a reproduction speed while maintaining a natural sound, by storing a signal, reproduced at a speed 1/n as high as a tape speed in recording, on a recording element, by reading the signal at an (n)-fold speed and repeatedly voicing it (n) times, and then reproducing one next cycle. CONSTITUTION:The speed of a tape driving motor 1 is set a half that in normal reproduction. A reproduction output from a reproucing head 3 is stored in a constant-speed memory 6 through an amplifier 4 and an AD converter 5. The output of this constant-speed memory 6 is sent a constant time after the start of the storage at a period a half that in reproduction. In the 1st one cycle, it is passed through a fundamental-wave gate 7 as it is and then reconverted into an analog signal by a DA converter 10. When a zero potential and a change direction are detected from a voice waveform by detecting circuits 13 and 14, a signal which has the same waveform with said signal is outputted as a replication signal from a modulative memory 8. The outputs of the detecting circuits 13 and 14 close a gate 7 and open a gate 9, so the replication signal is sent to the DA converter 10, thereby repeating the same waveform.
