Abstract: PURPOSE:To weaken strength against pressure by etching a diaphragm surface by strong alkali group chemicals and etching the diaphragm surface through a freon gas group plasma dry etching method. CONSTITUTION:A diaphragm surface is formed through a chemical wet type etching method by strong alkali group chemicals in the same manner as conventional devices. Diaphragm end sections 20 are formed to a sharp edge shape at that time, and strain stress by the etching of a diaphragm is applied previously at the diaphragm end sections 20. Silicon is etched through a freon gas based plasma dry etching method. Since the etching rate of a stressed section is faster than that of a unstressed section in silicon etching through the dry etching method, the stressed diaphragm edge sections 20 are formed to a recessed deviated circular shape.

Filed: 1981-07-02
Abstract: PURPOSE:To forcedly read an instruction for interrupt control by detecting coincidence between a previously set up address and an address to read out instruction data from a memory and latching these addresses up to the cycle executing the succeeding instruction. CONSTITUTION:When an objective address is detected from addresses applied from a line 1 and a register 3 by a comparator 4, the output of the comparator 4 is latched by D type flip-flops 7, 8 subjected to connect up to the cycle executing the succeeding instruction.

Title: Hot water supplying, bath heating and air heating apparatus
Inventor: FUJISHITA KAZUO
IPC: F24D3/08
Filed: 1986-05-08
Abstract: PURPOSE:To decrease cost and to reduce noise in the title apparatus, by forming an air heating circuit by connecting a hot water tank to a drip pot interposed by a check valve on one side and by connecting them by the intermediary of a pressure introducing valve on another side, and by forming a bath heating circuit by providing a heat exchanger for bath in the position lower than a water-level detector in the heat exchanger, while by providing a hot water supplier with a burner for feed hot water. CONSTITUTION:After a burner 25 is ignited, water in a heat exchanger 18 is heated to be turned into steam, which is fed into a radiator 20 through a steam pipe 19 by steam pressure. After heat is exchanged in the radiator, the steam is turned into condensate and is fed into a drip pot 23 passing through a check valve 22. After that a water-level detector 29 detects the water level when the quantity of hot water in the heat exchanger 18 lowers down to the line which is a little above the position of a heat exchanger 5 for heating of bathtub water. The internal pressure in the hot water tank is lowered by opening of a pressure introducing valve 28, and the condensate in the drip pot 23 is sucked into the hot water tank. The quantity of water in the tank is restored to the same level as before heating. In such a manner air heating operation is repeated by heating and evaporating cycles. Accordingly a circulating pump is not necessary on the side of an air heating circuit. Only one circuit pump is enough, so that cost is decreased as well as noise is reduced in the title apparatus.

The light whose power is attenuated in response to absorption spectrum of the natural Rb-D2 line is subjected to signal conversion by an element PD2, and input to an integrator B together with the output from the A1, which integrator is provided with a feedback resistor R0 and a capacitor C. Based on the fed back base voltage, a driving current I flows in the LD. As the result, it becomes possible to restrictedly use the slope Rb D2 line which is most suitable to narrow band application of spectrum line width, thereby a narrow spectrum line width is obtained.

Title: Reference voltage circuit
Inventor: ASAI KATSUO
IPC: G05F3/30
Filed: 1984-05-25
Abstract: PURPOSE:To obtain the reference voltage having no temperature coefficient by flowing a current having a positive temperature coefficient to a resistance and a diode which are connected in series in order to generate the reference voltage. CONSTITUTION:A transistor TR20 of a reference voltage circuit is connected to a diode, and the bases of TR22 and 24 are connected in common to the base and the collector of the TR20. Thus a current mirror circuit is formed and therefore a constant current circuit is obtained. A resistance 32 and a diode 34 are connected in series between the collector of the TR24 and an earth point. Then the reference voltage Vref is extracted out of the collector of the TR24. Thus a constant current is obtained from the constant current circuit consisting of TR20-24 as long as the current mirror ratio and the resistance values of resistances 30 and 32 have no change. This secures the stable constant voltage characteristics despite the variation of the power supply voltage. In addition, no constant current is needed separately and the monolithic constitution is possible with a semiconductor IC for a reference voltage circuit.
