Title: Power supply
Inventor: IWABORI YUTAKA
IPC: H02M7/217
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To enhance safety by connecting a first diode in the same direction as the DC output terminal of a full-wave rectifier, so that a current flows from an inductor through a second diode to a load circuit when a switching element is turned off, thereby preventing an undue input power from being fed, with respect to the output power. SOLUTION: The mode is switched when the sum (Vc1 +Vz) of the voltage Vc1 of a capacitor C1 and a load voltage Vz varies between the full-wave rectified output voltage |Vin| of an AC power supply P and the charged voltage VEC of a smoothing capacitor EC. When a switching element Q is turned off and |Vin|<Vc1 +Vz=VEC, a current flows through a path of an inductor LM, the capacitor C1, a diode D1, the smoothing capacitor EC and a diode D2 and a current also flows through a path of the inductor LM, a load circuit Z and the diode D2. According to the arrangement, an undue power is prevented from being fed with respect to the output power at the time of increasing the load, circuit current, and the safety is enhanced.

Title: Oscillation water spraying and pest control device
Inventor: NISHIMURA HIDEJI
IPC: B05B17/00
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily change over pest control work and water spraying work by arranging a liquid discharge section on an oscillation case, arranging a relief valve between the pressure chamber and wafer feed chamber in this oscillation case and making the release mechanism of this relieve valve operative from outside. SOLUTION: When a pressing plate 37 exists in an actuation position apart from a valve stem, the relief valve 35 maintains the pressure chamber A under a set pressure and the pressure water is discharged from a discharge port 22Fa or 22Ra to rotate a water wheel which in turn oscillates the oscillation case. The pressure difference between the pressure chamber A and the water feed chamber is lost and the water is no longer discharged from the discharge port 22Fa or 22Ra when the relief valve 35 is forcibly opened after the projection 38a of an external knob 38 turns to a release position where the projection fits into a recessed part 39a to maintain the pressing plate 37 in the position where the plate is pressed to the valve stem.  The water wheel does no longer rotate and driving power is no longer transmitted to the oscillation driving section, by which the oscillation is stopped and the execution of the water spraying work is made possible.

Title: Electronic flash device
Inventor: OKINO TADASHI
IPC: G03B15/00
Filed: 1980-11-05
Abstract: PURPOSE:To prevent the erroneous generation of a light emission stop signal owing to the influence of the junction capacity of photodetectors by providing a control circuit which starts integration after a prescribed time from the start of photometry. CONSTITUTION:On closing of a synchronizing switch 16, flash is started, and Zener voltage of a prescribed level is generated in a Zener diode 85 by receiving the voltage of a capacitor 31, and a dimming circuit A starts operating. This forces a transistor (TR)93 to conduct, thereby short circuiting an integrating capacitor 73. After the short time determined by resistors 89, 95, and a capacitor 91, said TR does not conduct, and the integration of the quantity of light is started. When the integrated value attains a prescribed value, a transistor 77 conducts, thereby stopping the light emission. If it is assumed that there is no TR93, the potential of the point P is determined by the junction capacity of a phototransistor 75 and the capacity of the integrating capacitor at the same instant of generation of the Zener voltage and therefore there is possibility of generation of an error signal.
