Title: Hot water feeder
Inventor: MAEDA TOSHIMASA
IPC: F23N1/00
Filed: 1988-10-31
Abstract: PURPOSE:To surely avoid the amplification of pulsation accompanying simultaneous ignition of both hot water feeder units by setting a time lag in valve opening operation of gas supply solenoid valves of the two hot water feeder units. CONSTITUTION:In the case where solenoid valves 13, 14 of a one-side hot water feeder unit U1 are opened first and ignition is performed, the secondary side pressure of the unit U1 fluctuate at large amplitude as soon as the ignition is performed, and thereafter the pressure is damped down to a constant pressure after a constant time elapses. On the other hand, valve-opening operation of the solenoid valves 13, 14 is detected by a sensor and a control device 40 opens the solenoid valves 13, 14 of the other side hot water feeder unit U2 after the time t of the elapse of a time lag preset by a timer while ignition is performed. The secondary side pressure of the unit U2 by the ignition fluctuates at large amplitude as soon as the ignition is performed, and thereafter the pressure is damped down to a constant pressure after the elapse of a constant time. Thereby, the production of composite secondary side pressure having the large amplitude and a long damping time produced in the case where the solenoid valves 13, 14 of both hot water feeder units U1, U2 are opened and the ignition is performed simultaneously can be prevented.

Abstract: PURPOSE:To provide an endoscopic device in which a fluorescent image can be picked up and displayed, together with an appearance image, only if fluorescence with more than predetermined luminous strength is detected. CONSTITUTION:When illuminating light involving excitation light is emitted from a light source 56, it is separated by a rotating filter 58 into normal illumination light and excitation light, which are then applied alternately to a subject 51 for inspection. The appearance image and fluorescent image of the subject for inspection are guided by an image guide fiber 53 and caused to impinge on respective first and second CCD cameras 62, 63. The fluorescence of the subject for inspection is detected by a photodetector 69 and only when its luminous strength is at or greater than a set value an image intensifier 65 is operated to double the luminous strength of the fluorescent image and then the image is picked up by the second CCD camera 63. At an image processing circuit 66 the fluorescent image is combined with the appearance image from the first camera 62 and the composite image is displayed on a monitor 67.

Title: Driving circuit for switching element
Inventor: WATANABE HARUO
IPC: H02M3/335
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate a malfunction that two switching elements are turned on at the same time by lowering an output impedance and holding the impedance low when on/off driving signals for the switching elements change from High to Low. SOLUTION: A first and a second driving section 14, 15 receive on and off signals alternately from a controlling circuit 2 and then alternately drive a first and a second switching element 5, 6. The controlling circuit 2 detects the voltage to be applied to a load 11 and then changes the oscillation conditions so that the voltage may be constant. When one of the switching elements 5, 6 turns on, the switching element is so controlled that the impedance at an input terminal may be small. By this method, the input terminal voltages of the switching elements 5, 6 are raised and thereby the two switching elements 5, 6 are turned on at the same time and then once-through current is allowed to flow and, as a result, the switching elements are prevented from being destroyed.
