Title: Gas alarm
Inventor: ISOBE FUMIHIDE
IPC: G08B21/00
Filed: 1997-04-02
Abstract: PROBLEM TO BE SOLVED: To reduce current consumption of a gas sensor by providing a power supply controlling means and a power supply intermittent means, supervising the operation state of a device and supplying operating power to the gas sensor while limiting it during a start time and a stop time. SOLUTION: A gas sensor 18 detects the concentration of prescribed gas. A sensor power source 21 supplies operating power to the sensor 18. An operation detecting means 13A detects the operation state of a device 22 which emits gas that becomes an object to be detected to the sensor 18 and creates an operation state detection signal 13a. A power controlling means 12 detects a start time of the device 22 in response to the signal 13a, generates a power connecting signal 12a, also detects a stop time of the device 22 and generates a power disconnecting signal 12b. A power intermittent means 14 connects the sensor 18 to the source 21 and makes it operatable in response to the signal 12a, and disconnects the sensor 18 from the source 21 and makes it in a stop state in response to the signal 12b.

Title: Variable venturi type carburetor
Inventor: KOGA ITSUO
IPC: F02M7/06
Filed: 1986-04-14
Abstract: PURPOSE:To supply optimum starting fuel according to engine temperature from an accelerating fuel system by supplying bleed air into the accelerating fuel supply passage of a variable venturi type carburetor through a means for controlling the bleed air quantity according to the engine temperature. CONSTITUTION:In a carburetor 1 with a variable venturi 3, accelerating fuel discharged by an accelerating pump 23 is supplied from a float chamber 7 to the nozzle 27 of a venturi part 8 through check valves 25, 28. Bleed air is supplied into an accelerating fuel passage 29 through a control valve 31 in which bimetals 43, 44, 45 change openings 50, 51, 52, 53 according to engine temperature. At the time when the engine is started, negative pressure in the venturi sucks the fuel from the float chamber 7, and the bleed air quantity for the said fuel is decreased by the control valve 31 as the engine temperature becomes lower. Therefore a large quantity of the fuel can be supplied.

Filed: 1987-04-06
Abstract: PURPOSE:To enable improving sealing properties of an apparatus while simplifying its structure by fixing an end plate at a yoke opening for insertion of a motor shaft and by forming an O-ring groove from said yoke and said end plate. CONSTITUTION:The sealing performance of an apparatus can be improved, because the fixed parts of an end plate 6 and a yoke 3 are sealed by an O-ring 41.

Title: Facsimile equipment
Inventor: HOJO YUJI
IPC: H04N1/04
Filed: 1985-04-19
Abstract: PURPOSE:To eliminate the distortion of an image without reversing and braking a stepping motor during transmission and to reduce noises generated by the stepping motor by providing a storage detecting means for one of two memories and a transfer means which transfers a read image signal to memory or from this memory to the other memory. CONSTITUTION:A page memory 4 is stored with the read image signal and a buffer memory 5 is stored with an image signal to be encoded. This buffer memory 5 includes the buffer memory 5a and 5b, which are put in partial charge of encoding and transfer alternately to prevent a decrease in encoding speed. A DMA controller 7 performs the DMA transfer of the image signals. When an original is long, a system control part 1 detects the storage of the memory 4 to stop the stepping motor right before the memory 4 becomes full, and reads several lines successively to perform transfer from the memory 4 to the memory 5. Then, when the read advances to a point which is N lines before a readout stop line, original feeding and reading are restarted, and the stop and restart of the reading are repeated. Thus, image distortion is eliminated and motor noises are reduced during transmission.
