Title: Floating well cmos output driver
Inventor: DANIERU DABURIYUU DOBAAPUURU
IPC: H03K19/0948
Filed: 1992-06-24
Abstract: PURPOSE: To simply interface chips designed to be operated at different voltages. CONSTITUTION: A VFG-floating gate circuit is provided to solve a problem that a transistor(TR) Q1 is conductive, when a level (Vo-Vp) exceeds a threshold voltage. When a Vo is less than a bias voltage Vdd, a VFG voltage may be VP. However, when the Vo exceeds the Vdd, the VFG voltage in following the Vo is equal to Vo. Thus, the VFG circuit prevent the TR Q1 from being conductive, when the Vo is more than 3.3V and logical 1. Similarly, a VFW- floating well circuit is provided. When the Vo is less than the Vdd, a voltage of the VFW is equal to the Vdd. However, then the Vo is more than the Vdd, the VFW in following to the Vo is equal to the Vo. The VFW circuit prevents a parasitic diode of the TR Q1 from being conductive in a forwardly graded way, when the Vo exceeds the Vdd and is logical 1.

Abstract: PURPOSE:To recover the total load through a recovery turbine by delaying an output signal from a top gas pressure regulator by transmission delay of a control system by a primary delay computing element, synchronizing the delay signal with a governor output signal and preventing a septum valve from being opened by a transmission delay of the control system. CONSTITUTION:The deviation of a set value SV of the top gas pressure from a top gas pressure PV is inputted into the governor 12 as an output signal MV. Then, an output signal E1 of the governor 12 is transmitted to a driving circuit 15 through an A/V converter 14 to switch and control the governor valve 4. On one hand, the signal MV out of the top gas pressure regulator 10 is transmitted by the primary delay computing element 18 to an computing element 17 as a delay signal E2, signals E2 and E1 are subtracted, the septum valve 6 switched and controlled by the subtraction signal E0 through a comparative setter 19. When a transmission delay time on the control system side of the governor 12 is set by the computing element 18 in advance, both signals E1 and E2 inputted into the computing element 17 are synchronized when a trip signal 20 is not inputted. Accordingly the subtraction output of said signal becomes zero, the valve 6 is closed and the loss by the bypath can be avoided as regards the quantity of the passing gas.

Abstract: PURPOSE: To enable a radio transmitter-receiver to transmit HF pulses and to use a single antenna for receiving HF signals by providing a switching device which connects a damping member to an antenna resonance circuit upon receiving a switching voltage. CONSTITUTION: When a start switch 16 is actuated, an AC voltage is induced in a winding W2 and applied to a damping circuit 24 and, as a result, a positive voltage and a negative voltage are respectively generated in capacitors C1 and C2 and the capacitor C2 starts an HF interrogating pulse. When the interrogating pulse ends, the negative charged voltage of the capacitor C2 starts to drop and a transistor T1 is conducted by a positive voltage jump at the emitter of a transistor T3 through a capacitor C3. When the voltage of the emitter rises and becomes higher than the threshold electric fields of transistors T4 and T5, a damping member composed of resistors R4-R6 is connected in parallel with the capacitor CA1 of an antenna resonance circuit 28.  Thus the circuit 28 is actuated in a fully automated state when the HF interrogating pulse is generated and an answer is immediately returned by means of a transponder 26 when the interrogating pulse ends.

Filed: 1980-11-26
Abstract: PURPOSE:To achieve AC drive without deteriorating scattering characteristics of a liquid crystal cell by charging liquid crystal between a semiconductor substrate and a transparent piezoelectric substance which has transparent conductive layers adhered to both its surface. CONSTITUTION:A video signal voltage is applied to liquid crystal 14 from a metallic reflective electrode 7 on a silicon substrate 10, where an integrated circuit is formed, and a transparent electrode 14.
