Title: Liquid level detecting device
Inventor: YAMAKAWA TSUTOMU
IPC: G01F23/22
Filed: 1988-11-30
Abstract: PURPOSE:To surely detect liquid level with a simple constitution by providing a diode which applies a forward current and deciding based on the drop amount of forward voltage whether or not the diode is immersed in low temperature liquid. CONSTITUTION:A certain forward voltage V0 is supplied to the diode 12 and a decision circuit 15 by a power source 13 through a resistance 14. When silicone diode, for example, is used as the diode 12, temperature dependency appears and the drop of the forward voltage of the diode 12 is changed. The drop of the voltage becomes large since the temperature of the diode 12 is low when it is in the low temperature liquid. When the diode 12 is in the air, the temperature thereof is higher than that in the liquid, so that the drop voltage of forward resistance becomes small. The voltage V0 changes according to whether or not the diode 12 is under the liquid. Whether or not the diode 12 is under the low temperature liquid is discriminated based on the voltage V0 in the decision circuit 15, thereby detecting the surface of the low temperature liquid.

Title: Contact material for current breaker in air
Inventor: SHIBATA AKIRA
IPC: H01H1/023
Filed: 1987-12-02
Abstract: PURPOSE:To secure a constant contact resistance even after closing and opening the contact many times, to maintain a balanced and smooth consumption surface constantly, and to obtain an anti-deposition property to a current of the middle class to the large class load, by dispersing a specified heat resistant finely divided powder in an Ag matrix containing 0.05-10wt.% Bi, and subjecting sintering thereto. CONSTITUTION:A heat-resisting minute powder including 3 to 80wt.% of one or more of W, Mo, Fe, Co, Ni, Cr, and Ti, their carbonates, and carbon, is dispersed in a silver matrix including 0.05 to 10wt.% of Bi, and it is sintered and formed. Since the surface of an electric contact to close and open in the air is heated up to the melting point of silver or higher, and absorbs oxygen before a heat-resisting metal and carbon in the silver matrix are oxidized, making the Bi on the surface of the silver matrix into a Bi oxide, the surface of the contact is purified by the Bi oxide. And by including Bi more than its solid solution limit, the anti-deposition property, the reduction of contact resistance, and the durable life are improved without losing the anti-arc property too much.
