Title: Thermostat for cooling water of engine
Inventor: FUKUMURA KEIICHI
IPC: G05D23/02
Filed: 1981-06-03
Abstract: PURPOSE:To obtain the titled thermostat with which the time for injecting the cooling water into an engine can be sharply reduced when the thermostat is first incorporated into the engine and is capable of performing the normal function once the engine is started by a method wherein a thermosensitive element, a main valve and a resilient space keeping member are provided. CONSTITUTION:In a condition in which the engine is not started, the space keeping member 7 bends a leaf spring 7b and is kept projecting into a path in which the main valve 3 moves toward a valve seat 4a while, in this case, the thermosensitive element 1 does not expand so that the main valve 3 is pressed against the valve seat 4a by a spring 2 and is in engagement with the leaf spring 7b. Accordingly, air is removed well at the time of injection of the cooling water into the engine since the main valve 3 is opened and not much time is required for the injection. Thus, when the engine is started, the main valve 3 moves downward through the operation of the thermosensitive element 1 to thereby make the thermostat perform the normal operation.

Title: Apparatus for inspecting transistor
Inventor: ITO MASATAKA
IPC: H01L21/66
Filed: 1991-04-18
Abstract: PURPOSE:To measure a characteristic of a transistor in a non-contact state, by using the voltage measurement circuit having an input impedance greater than a certain impedance, which is calculated based on a measuring electrode provided opposite to the measurement surface of the electrode or wiring of the transistor and based on the leakage current of the transistor. CONSTITUTION:A capacitor 201 is formed between the measurement surface of a wiring 106 and a measuring electrode 1. When a pulse voltage is applied to a gate electrode 103 and the gate is opened, the potential value of the wiring 106 in connection with a drain electrode 105 is brought into Vin, and at that instant, the potential value of the opposite measuring electrode 1 thereto is raised to Vin, too. Then, at a time t=T1, a transistor 102 is turned off, and in this state, the potential value of the measuring electrode 1 is fixed into V1. If there is a leakage in the transistor 102, the potential of the drain electrode 105 is attenuated with a time constant tau=RoffC, and accompanied by this, the potential of the measuring electrode 1 is attenuated too. Thereby, the characteristic of the transistor can be measured in a non-contact state.

Filed: 1979-07-06
Abstract: PURPOSE:To always secure the synchronization with a comparatively low frequency of the reference oscillator, by holding the control signal when no audio signal exists and then controlling the oscillation frequency when the audio signal exists respectively. CONSTITUTION:In case no signal exists at audio input terminal 9, switch circuit 2 is turned on along with switch circuit 6 connected to the 6b side. The phase synchronous loop is formed by phase comparator 3, LPF4 switch circuit 6 and voltage control oscillator 7. And the oscillation frequency synchronized with the frequency of reference signal generator 1 is delivered from oscillator 7. At this moment, sample holding circuit 5 holds the output of LPF4. Then in case when the signal exists at terminal 9, switch circuit 2 is turned off with circuit 6 connected to the 6a side. And oscillator 7 is controlled by the holding voltage of circuit 5 and then has the oscillation with the same frequency as when the loop is formed. Thus the frequency modulated signal with the above-mentioned frequency defined as the carrier can be obtained. In this way, the oscillation frequency can always be synchronized with oscillator 1.
