Patent JP-H06260146-A (JP)
Title: Discharge lamp
Inventor: SENZAKI SHIGERU
IPC: H01J61/52
Filed: 1993-03-08
Abstract: PURPOSE:To reduce the number of processes for assembling, enhance the easiness in the assembly works, and reduce the costs by forming a heater from a conductive metal foil, and adhering the heater fast to the outer surface of a bulb using a heat-resistant, insulative adhesive. CONSTITUTION:By the use of a heat-resistant, thermally acting adhesive 14 of silicon, etc., a heater 13 for low temp. compensation is adhered to the outer surface of the bulb 12 of a discharge lamp concerned 11, over approx. the overall length. The heater 13 is formed by punching off a conductive metal foil using a press etc., and current is fed for heating when electric connection is generated with a power supply 15 and the ambient temp. remains low, and thus the bulb 12 is heated. Accordingly the heater 13 can be mass-produced simply and quickly from metal foil through press processing, and because this is adhered fast to the outer surface of the bulb 12 with adhesive 14, no thermo- contractive tube or the like is required as otherwise used in the conventional structure, to lead to reduction of the number of component parts. Thereby the man-hous in processing can be decreased, so that the easiness in assembly works can be enhanced and the costs be suppressed.

Abstract: PURPOSE: To join a gear to a gear-fitting part in a furnace so as to manufacture a speed change gear in a short time with reduced energy consumption, by fitting a gear to be joined to the gear-fitting member, by supplying brazing metal to the fitting part, then by heating the gear and the fitting part in a furnace at a temp. not lower than the m.p. of the brazing metal.  
     CONSTITUTION: A solid brazing metal is supplied to the fitting part of a shaft 8 and a gear 9 to be fitted, then the shaft 8 is placed in a furnace. The furnace is evacuated and heated to a temp. not lower than the m.p. of the btazing metal and is kept at the temp. in order to make the molten brazing metal flow into the fitting part. Suceesively, the furnace is cooled to a temp. a little lower than the m.p. of the brazing metal. After that, a carburizing gas is added to the inside of the furnace in order to conduct carburization and diffusion, followed by gas cooling and reheating. The fitting part is colled with oil in a quenching oil tank installed in the furnace, thereby completing brazing and carburization.

Filed: 1988-02-29
Abstract: PURPOSE:To reduce a switching loss of an inverter circuit by employing a constant-current source, connecting an inductor and a capacitor in series with the current source, and connecting a switching element connected in parallel with a diode in parallel with the current source. CONSTITUTION:A constant-current source is provided as a power source, and a series circuit of an inductance L1 and first and second capacitors C1, C2 is connected to the source 3. A switching transistor(Tr) Q1 is connected in parallel with the series circuit. A capacitor D1 connected reversely to the Tr Q1 is connected in parallel with the Tr Q1. A load 4 such as a discharge lamp or the like is further connected through an inductor L2 of an impedance element to both ends of the capacitor C2. Thus, when the Tr Q1 is turned ON, a series resonance circuit of the inductor and the capacitor is formed, and its resonance current flows to the Tr Q1. Then, the Tr Q1 is switched at a zero current point, thereby reducing its loss.

Title: Method for correcting evaporation of photographic developing device
Inventor: FUJITA YOSHIHIRO
IPC: G03D3/06
Filed: 1990-02-28
Abstract: PURPOSE:To allow the correction of evaporation without changing the concn. of processing liquids by returning a processing liquid level up to an original liquid level by executing water replenishment after a prescribed quantity of photosensitive materials are processed, then supplying a prescribed volume of a replenishing processing liquid and discharging the liquid by overflow by as much as this replenishing processing liquid. CONSTITUTION:The developing soln. volume V1 carried in by sticking to the photosensitive materials F per unit area from a developing tank 12 and the bleach processing liquid volume V2 carried out to a bleach-fixing tank 16 by sticking to the photosensitive materials F are approximately equaled in a bleaching tank 14 and, therefore, the replenishing water in a tank 36 is supplied thereto when the liquid levels falls after the prescribed quantity of the photosensitive materials F are processed. The fatigue of the bleaching liquid is remedied by supplying the replenishing processing liquid (liquid volume VR) to the bleaching tank 14 by using a pump 38 after the liquid level is reset to the original liquid in such a manner. This supply volume VR is proportional to the processing quantity of the processed photosensitive materials F and the bleach processing liquid in the bleaching tank 14 overflows by as much as this supply volume and is discharged from the bleaching tank 14. The evaporated water is replenished without changing the concn. of the processing liquids in this way.
