Title: Driving device of fuel injection valve for internal combustion engine and injector driving device
Inventor: MARUMOTO KATSUJI
IPC: F16K31/06
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To hasten the start time of driving current of an injector by composing a means (for example, a semiconductor switching element) for forming the current-carrying circuit of a fuel injection valve coil, and a means (for example, the other semiconductor switching element) for regulating the magnitude of current which flows its circuit. SOLUTION: When an injector command P1 is inputted for a period (TINJ), power (MOSFETMO4) is turned on during its inputting, its period (PWM) signal is also inputted, and (PWM) operation is carried out by power (MOSFETMO1). Namely, injector current (IINJ) flows the power M04, an injector coil 40, the power MO1, a RSN, and a GND passage in order by output voltage VDC of a boost circuit at the time of the on time of one cycle of the PWM signal. When the PWM signal is turned off, the power MO1 is turned off, the injector current IINJ flows as circulating current through the reverse diode of power M0SFETM03, the power MO4, the closing circuit of the injector coil in order. It is thus possible to change the magnitude of the injector current IINJ value by controlling duty (ON/ON+OFF) of the PWM signal.

Title: Radio selective paging receiver with infrared interface
Inventor: TSUKUDA NAOKI
IPC: H04B10/00
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To improve the operability of the receiver without attaching a remote control or newly purchasing it by inputting characters by using an infrared remote control of television, etc., when generating an address book, etc. SOLUTION: The read-only memory 105 of the receiver is stored with the remote control signal formats of television of respective manufacturers and when a television manufacturer's name is selected first through an operation part 101, its information is written in a rewritable memory 106. When the receiver is placed in address book input mode through the operation part 101, it automatically becomes possible to input characters through the remote control 10 of television. A signal sent with a button of the remote control 107 pressed is received by the infrared interface 102, and processed by a control part 103 to display corresponding characters at, for example, a display part 104. Character input is carried out by using channel buttons of television.  Number/Japanese syllabary switching is done with a power button and at the time of Japanese syllabary input, characters change each time a channel button is pressed. A character is decided with a sound volume button.

Filed: 1984-09-30
Abstract: PURPOSE:To enhance the safety by providing a reverse voltage protecting circuit between the bases and the emitters of a pair of transistors in a feedback circuit, thereby reducing a switching loss. CONSTITUTION:A transistor inverter is composed of transistors (Tr)1, 2, a transformer 3, a resonance capacitor 4, a constant current inductor 5, a feedback winding 6, and an inductor 7. In this case, a reverse voltage protecting circuit 8 is provided between the winding 6 and the bases, emitters of the Trs 1, 2.

Title: Water level control of cistern in hot water supply heater with reheating functions
Inventor: OCHI MIKIO
IPC: F24H1/46
Filed: 1990-07-31
Abstract: PURPOSE:To inhibit a rise in a water level and hence prevent overflow by throttling a hot water supply valve based on a specified flow rate when it is detected that the water level in a cistern remains continuously within a specified range for more than a fixed time. CONSTITUTION:When a water level detection means installed to a cistern 60 detects that the water level is in a predetermined zone C, a hot water supply mount valve 26 is throttled for 20 seconds so as to reduce the injection amount of hot water to the cistern 6 by 0.5l/min during that period. When the water level rises and reaches the zone D in spite of the above operation, the hot water supply amount valve 16 is throttled in continuous mode so as to reduce the injection amount to the cistern 60 by 0.5l/min. When the water level drops down to the zone B, the throttling of the hot water supply amount valve 26 is released so as to increase the flow rate. Since the injection amount of hot water to the cistern 60 is reduced in this manner, the difference between the injection amount and the supply amount is minimized so that the fluctuation in the water level may be slow, which makes it possible to control water level control easily and prevent the hot water from overflowing in the cistern.
