Title: Constant voltage circuit
Inventor: ISHIKAWA HITOSHI
IPC: G05F1/56
Filed: 1985-06-12
Abstract: PURPOSE:To naught the modulation effect of the base width of a control transistor by applying the reference voltage to the 1st input/output electrode of an output control transistor via the 2nd transistor and the 1st load and fixing the control electrode and the 1st input/output electrode by the reference voltage. CONSTITUTION:The collector potential VC4 of an output transistor TR4 is defined as VC4=VZ-VBE11+VF13 (VZ: the reference voltage of a constant volt age diode 1, VBE11: the base-emitter voltage of a TR11 and VF13: the forward voltage of a p-n junction diode 13). Here the VF13 is approximately equal to the VBE11 in terms of the voltage drop characteristics of the p-n junction. There fore the VC4 is approximately equal to the VZ. Thus the collector-emitter voltage is always equal to the base-emitter voltage for the TR4. Then these voltages are fixed by the reference voltage VZ and therefore the TR4 receives no modula tion effect of the base width despite the variance of the power supply voltage. Then the emitter potential of the TR4 has no variation.

Title: Protective circuit for input and output
Inventor: ICHIKAWA TSUTOMU
IPC: H01L27/04
Filed: 1993-04-30
Abstract: PURPOSE:To increase electrostatic breakdown voltage by facilitating the operation of parasitic bipolar transistors in many NMOS transistors, at the time of discharge. CONSTITUTION:The gates 16 of NMOS transistors 13 are grounded via a series resistance element 21. When a positive high voltage pulse whose rise time is very short is applied to an I/O terminal 11, the gate voltage increases up to a voltage wherein the voltage between the drain 14 and the source 15 is divided by parasitic capacitors 22, 23. Hence the NMOS transistors 13 turn to conduction state or an approximate to it at the time of discharge, so that the parasitic bipolar transistors in many NMOS transistors become easy to operate.

Abstract: PURPOSE:To positively operate an integrated circuit at the time of a test to generate an internal heat, and to improve the reliability of the test by receiving a selective control signal corresponding to the system operation mode and test mode of the integrated circuit, selecting the output of an FF circuit at the time of a system operation, selecting a clock synchronizing signal at the time of the test mode, and supplying it to a corresponding logic circuit. CONSTITUTION:When an output selective controller 13i receives a selective control signal from a selective control signal generator 14, it selectively controls a clock synchronizing signal from a clock synchronizing signal generator 15, and supplies it to a corresponding predetermined logic circuit. Thus, each logic circuit 12j (j=1-m) in an integrated circuit operates at random by the clock synchronizing signal input from the corresponding output selective controller, and generates an internal heat. Thus, the burn-in test of the integrated circuit can be conducted by adding the simple selective control signal generator and the output selective controller without using a scanning system. Thus, the integrated circuit can be effectively used for its original logic circuit operation.

Filed: 1986-06-03
Abstract: PURPOSE:To obtain the correct value of an error when a rotational direction changes and accurately correct the output of a bearing detector by providing means for judging that a moving object rotates by one revolution in either rotational direction judged by rotational direction judging means. CONSTITUTION:Rotational direction judging means 2 judges in which of two rotational directions a moving object rotates. Selecting means 3 selects either of the two rotational directions for the output of a bearing detector 1 based on the rotational direction judged by the means 2. Further, one revolution judging means 4 judges one revolution based on the output of the detector 1 selected by the means 3. Thus, the one revolution is judged for every rotational direction of the moving object. That is, whether the rotational direction is clockwise or counterclockwise is judged, the output of the detector 1 is selected by whether the means 3 selects the clockwise or counterclockwise rotational direction and the means 4 judges the one clockwise revolution from the output of the detector 1 in the clockwise rotation and the one counterclockwise revolution from the output of the detector 1 in the counterclockwise rotation. When the one revolution in either rotational direction is judged, the output of the detector 1 is corrected based on the error of the one revolution.
