IPC: G06F1/32
Filed: 1995-07-14
Abstract: PURPOSE: To make low power consumptiveness higher than that in the current state while maintaining and improving high-speed operativeness and reliability. CONSTITUTION: The semiconductor device can switch the source voltage of some area in itself, a constant voltage circuit 104 which generates source voltages can generate the source voltages of at least three levels, and a control means 103 outputs the respective source voltages in order from the source voltage which is large (or small) in absolute value when the source voltages are switched, thereby switching the source voltages stepwise. Therefore, even if the potential shift of a signal line is delayed behind the shift of the threshold value of a digital circuit right after the source voltages are switched, data are never inverted and the circuit does not malfunction, so that the reliability does not decrease.

Title: Solar heat collector
Inventor: GOTOU KOUJI
IPC: F24S90/00
Filed: 1982-11-16
Abstract: PURPOSE:To reduce heat loss and to prevent a heat collecting pump from sucking a gas by a method wherein steam generated in a heat collector is separated by a gas- liquid separator, flowed into an expansion tank, condensed by being made to exchange heat with the open air by using a radiator and collected in the expansion tank. CONSTITUTION:When a liquid heat medium in a heat collecting backward pipe 6 is heated to a dangerous boiling temperature during a heat collecting operation, the heat collecting pump 4 is stopped by a signal from a thermosensor 15 to thereby prevent the pump from sucking the gas. Due to the stoppage of the heat collecting pump 4, the liquid heat medium in the heat collector 1 boils to become the steam. Then the steam is separated by the gas-liquid separator 16 in the backward pipe 6, transferred to the expansion tank 9 through a steam pipe 18, condensed by being made to exchange heat with the open air through the radiator 17 and collected in the expansion tank 9. Thus, when the operation of the heat collecting pump 4 is interrupted forcibly, the steam is re-condensed and collected in the expansion tank 9 so that the quantity of the liquid heat medium is hardly reduced and the number of supplies of the liquid heat medium can be minimized. Further, it is possible to prevent an increase in the loss of heat radiation at the time of heat collecting operation and also to prevent the heat collecting pump from sucking the gas.

Title: Manufacture of gas-inductive body material
Inventor: SAKAI MASAYUKI
IPC: G01N27/12
Filed: 1982-11-18
Abstract: PURPOSE:To make the shape and diameter of powder particles uniform and to decrease the variation of gas inductive characteristics by applying a precipitation forming reaction utilizing a hydrolysis of urea to the adjustment of the raw material powder of a gas-inductive body. CONSTITUTION:Indium chloride, ammonium sulfate and urea [(NH2)2CO] are dissolved in water and stirred while heating them on a hot plate. The heating is conducted e.g. at >=95 deg.C temp. The coprecipitated material is filtered by sucking, the obtained powder is fed into evacuating vessel for vacuum drying, pulverized by an automated mortar, and then adjusted to particles of the size of about 100-200mu by using an organic binder. Two platinum wires as serving as an electrode are embedded into this powder, then pressformed, and ignited in air to manufacture a gas inspecting element. This gas inspecting element has small variation of the gas-inductive characteristics because the shape and diameter of the raw material powder of the gas-inductive body are uniform, and the characteristics are stable for a long time.
