Title: Power switch interlocking circuit
Inventor: FUKASE TAKAYUKI
IPC: H02J3/00
Filed: 1991-01-24
Abstract: PURPOSE:To eliminate operation miss by providing means for detecting an alternating current flowing through a line and a switching means comprising a MOSFET transistor being driven by a detection signal of the current detecting means. CONSTITUTION:Upon turn ON of an AC power switch 12 connected with a receptacle, a device A functions and a current l4 flowing through the device A is fed through a current transformer 2 to induce flux phi15. Consequently, a voltage v16 is induced across the winding of the current transformer 2. Thus induced voltage is then rectified through a rectifying circuit comprising a diode 3 and applied across a resistor 4, i.e., between the gate and the source of a MOSFET transistor 5, thus bringing the MOSFET 5 into conducting state. Consequently, power is fed from the receptacle through the rectifying circuit comprising the diode 6 and through the drain-source of the MOSFET 5 to a device B. According to the invention, operation miss can be eliminated.

Filed: 1994-01-26
Abstract: PURPOSE:To provide a method and on apparatus for measuring thermal conductivity of a novel thermal insulating material by providing a heat flowmeter for measuring the density of heat flow in the longitudinal and lateral directions. CONSTITUTION:A highly heat insulating standard sample S having known thermal conductivity is set, at first, on the apparatus and longitudinal heat flowmeters fu, fe are calibrated. On the both sides of the standard sample S, a skin material, i.e., a sheet-like sample C is closely attached and fitted. There is a difference between the temperatures T1, T2 in the upper and lower central parts of the sample C and the ambient temperature Ta=1/2(T1+T2). If T1>T2, heat flows from the central part of surface sample C toward the periphery and from the periphery of rear surface sample C toward the center with density of Fuh, Feh, respectively. Since the skin material is normally quite thin, the total heat resistance of the sample C in the thickness direction is 10<-5> or less which is quite lower than that of the sample S. A thermal insulating material is set in the apparatus having calibrated values and the thermal conductivity is determined by reading out four outputs in both directions after settling to steady state.
