Filed: 1986-07-09
Abstract: PURPOSE:To considerably improve sensitivity by using a high-polymer piezo-electric film which is corrugated and is concentrically formed with waves so that the film is largely deformed and the large electric power is obtd. even if the force acting thereon is small. CONSTITUTION:Electrode 2, 3 are formed on both faces of the corrugated high- polymer piezo-electric film 1, by which the main body part is constituted. The waves of the film 1 form concentrical circles are equal pitches. The main body part is sandwiched by two sheets of upper and lower thin annular metallic holders 4, 5 and are further adhered and supported into another plate holder 6 made of a metal or synthetic resin, etc. having rigidity. The film 1 of such sensor is deformed and the voltage corresponding to the amt. of deformation is generated between the electrodes 2 and 3 when force acts on the upper or lower side face of the main body part. Since the magnitude of the voltage corresponds to the force acted thereon, the magnitude of the force is known therefrom.

Filed: 1984-07-30
Abstract: PURPOSE:To enable to obtain stable reference voltage without increasing electric power consumption for variation of load by connecting an operational amlifier having connected inversion input end with an output end to the output end of a reference power source. CONSTITUTION:As the inversion input terminal and output terminal 21 of the operational amplifier 22 are connected directly, gain of this operational amplifier 22 becomes 1, and voltage of non-inversion input appears in the output end 21. Further, as output impedance of the operational amplifier 22 is as low as less than 1, potential of the output end 21 does not change even when load of the operational amplifier 22 changes. Accordingly, by using this circuit as the reference voltage generating circuit of switched capacitor integrators 23, 24, stable reference voltage is supplied and characteristic of the integrators 23, 24 becomes stable. As stable reference voltage is obtained even if large electric current is not let flow in resistances 18, 19, it is suitable also for an integrated circuit.

Filed: 1988-06-30
Abstract: PURPOSE:To prevent thermal destruction of members having a low thermal resistance and thermal degradation of various parts constituting a heating device by detecting the abnormality of a temperature detecting means by off-start of power supply of a heating body. CONSTITUTION:When a timer 8 is started and a changeover switch 13 of a capacitor 11 is switched to start charging of the capacitor 11 through a fixed resistance 2a, the voltage outputted to a pulse width modulating circuit 3independently of the actual temperature of a fixing device falls to potential level 0 and is restored to a voltage level corresponding to a detected temperature S of the fixing device based on a prescribed time constant thereafter. When as voltage level Vs outputted to the pulse width modulating circuit 3 is lower than a voltage level corresponding to an upper limit reference temperature Tu after a prescribed time T elapses, it is judged that a thermistor 2b is short- circuited; and when the voltage level Vs is lower than a voltage T1 corresponding to the rise temperature, it is judged that the thermistor 2b is disconnected, and the control operation is stopped. Thus, degradation and thermal destruction of various parts constituting the heating device are prevented.
