Title: Gas hot water heater
Inventor: NAKAJIMA SHINYA
IPC: F23N1/08
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To secure discharging time needed for ignition at an igniting operation by starting energizing a magnet safety valve to open the valve before a spindle is disengaged from a valve opening device and starting discharging for ignition before opening of the safety valve is started and stopping the discharge when a certain period of time has elapsed right after opening of a hydraulic automatic valve has started. SOLUTION: Before a spindle (SP) 37 is disengaged from a valve opening device (OV) 8, energization of a magnet safety valve (MV) 7 is started to generate electromagnetic force to hold the valve opened. Therefore, when the MV 7 is opened and pushed, electric current is assured to flow so that the MV 7 is kept opened. And before opening of the MV 7 is started, discharge for ignition is started, and when a specified period of time has elapsed right after the starting of opening of a hydraulic valve (WV) 30, the discharge is stopped so that explosive ignition is prevented from occurring even if abnormality in valve closure should occur in the WV 30. Even if opening of the WV 30 is delayed due to water pressure and the like, discharging time needed for ignition is secured and safety can be enhanced.

Title: Inverter
Inventor: YAMASHITA TAKESHI
IPC: H02M7/537
Filed: 1993-12-24
Abstract: PURPOSE:To minimize a switching time and reduce a loss in switching in an inverter. CONSTITUTION:When an output current signal from an inverter is reduced and the voltage is lowered than a reference voltage (Va), a comparator 16a starts to operate and a switching element 2a is driven through buffers 14 and 14a. A discharged current from a gate is passed through gate resistors 15 and 15a. The gate resistors 15 and 15a are connected in parallel and the apparent resistance is reduced so that an input capacity of the switching element 2a has a shorter discharging time. Then, the switching time is reduce. In addition, a comparator 16b, 16c and so on that become lower than reference voltages (Vb, Vc, and so on) are sequentially operated. In this way, the switching time of the switching element 2a is reduced, and the loss in switching is much reduced. As for a surge voltage, a switching time is reduced, but the output current signal from the inverter is made smaller, so the surge voltage is held almost at the same level as before.
