Title: Corrosion resistance maintaining device for engine cooling liquid
Inventor: ARAI HIROYUKI
IPC: F01P11/06
Filed: 1994-03-16
Abstract: PURPOSE:To improve corrosion resistance performance of a corrosion inhibitor in engine cooling liquid by providing a dissolved oxygen supplying means for supplying oxygen into the engine cooling liquid in an engine cooling system using the engine cooling liquid containing an inorganic corrosion inhibitor. CONSTITUTION:The oxygen amount is judged by a detecting signal of a dissolved oxygen detecting sensor 3 in a controller 3b during the operating of an engine, whether the amount is less than 4ppm or not. When the result is Yes, a switch 4c of an electrolyzing device 4 is turned on, and the water in engine cooling liquid is partially electrolyzed, so as to generate oxygen near a positive electrode 4a and hydrogen near a negative electrode 4b. This hydrogen is accumulated on the projecting part 1f provided on the upper part of a radiator and then discharged into a reserve tank 2 by opening of a pressurizing valve 1a. And the anode reaction rate of an inorganic corrosion inhibitor having no self-oxidizing force, such as phosphate, molybdate, etc., in the cooling liquid is decreased by the generated oxygen, and so as to provide corrosion resistance.

Title: Vapor phase reactor
Inventor: SUZUKI NAOKI
IPC: H01L21/205
Filed: 1984-03-09
Abstract: PURPOSE:To enable the reduction in crystallogical slippage by growing a more uniform film on a semiconductor substrate by placing a guartz plate in the outer peripheral surface of a susceptor. CONSTITUTION:A semiconductor substrate 16 is placed in a reaction chamber 9, and the susceptor 21 made of a material such as graphite of large thermal conductivity is installed at the position opposed to an infrared ray lamp heater unit 13 across a transparent quartz plate 14. Further, there is a ringlike auxiliary base 22 made of opaque quartz which surrounds the outer periphery of the susceptor 21, which is nearly coincident with the susceptor 21 in level. The quartz plate 22 receives the radiated heat out of the unit 13 from above, receives the release of heat out of the susceptor from inside, and thus release heat only to the bottom and to outside. However, because of a small thermal conductivity, a uniform temperature distribution can be obtained on a susceptor 6.

Title: Sense amplifier
Inventor: NARAHARA TETSUYA
IPC: G11C11/419
Filed: 1989-02-27
Abstract: PURPOSE:To prevent malfunction occurring in the readout operation of the content of a memory by keeping the logical threshold voltage of an inverter circuit constant even if the source voltage of a sense amplifier in a semiconductor circuit device is fluctuated by a noise, etc., transiently. CONSTITUTION:Assuming the threshold voltages of P-type MOSFETs 1 and 2 in the sense amplifier as VTP1 and VTP2, respectively, the voltage V21 of a second connection point A2 goes to VDD-(VTP1+VTP2), and since the connection point A2 is coupled with the source voltage VDD and a capacity element C, it follows the fluctuation of the voltage VDD. Thereby, a voltage VGS(3) between the gate and source of a P-type MOSFET 3 can be kept constant even if the voltage VDD is fluctuated by DELTAVDD, and the logical threshold voltage of an inverter consisting of FETs 1-4, a resistance element R, and the capacity element C can be kept constant. And the on-state of an N-type MOSFET 5 can be set even if the noise is generated at a source voltage terminal when a current flows on a selected cell, and the constant level of a sense amplifier output terminal 8 can be obtained, and the current can be permitted to flow on the selected cell, and the high level of the terminal 8 can be maintained by turning on the FET 5, and the malfunction can be prevented occurring in either case.

Filed: 1980-04-08
Abstract: PURPOSE:To raise the efficiency of demodulation and simplify the structure, by discriminating a varied portion of quenching oscillation frequency of the quenching oscillating circuit, and demodulating directly, when an input signal has been received. CONSTITUTION:When the point A has received an input, the resonance frequency of the resonance circuit 23 of the quenching oscillating circuit 8 is varied, its varied portion exerts influence on quenching oscillation, and the level, waveform and frequency, of quenching oscillation are varied. An output of the quenching oscillating circuit 8, whose frequency has been varied is input to the demodulation means 21 through the waveform shaping circuit 22. That is to say, when a signal whose frequency has been varied is input to the demodulation means 21, since this demodulation means is a PLL circuit, said signal is output as a demodulated signal output of DC level when the frequency is varied.
