Title: Switching method for multiplied sine wave oscillator
Inventor: HONDA NAGANOBU
IPC: H03L7/00
Filed: 1979-06-20
Abstract: PURPOSE:To obtain nearly the continuous sine waves by immediately switching the oscillator to the backup sine wave oscillator in case the fault of the sine wave oscillating circuit is detected by the logic sum of the output of the comparator and the one-shot circuit. CONSTITUTION:The full wave rectification is given to the output of sine wave oscillator 2, and then the output of oscillator 2 is compared 5 with the level set by level setter 4. Thus the value exceeding te set level is detected, and the inversed signal of the output of comparator 5 is applied to one-shot circuit 7. Both the outputs of circuit 7 and comparator 5 are supplied to logic sum circuit 8. And in case oscillator 2 has the normal oscillation, analog gate 10 is turned on to extract the output. Gate 10 is turned off when oscillator 2 discontinues the oscillation. Then analog gate 11 is turned on via NOT circuit 9, and oscillator 2 is switched to sine wave oscillator 1. In other words, the fault of the sine wave oscillator is detected immediately to perform the switching from the using side oscillator to the backup oscillator. In such way, nearly the continuous sine waves can be obtained.

Title: Power generating system of taking advantage of quenching phenomenon in superconduction
Inventor: ISHIDA NOBUO
IPC: H01F30/00
Filed: 1995-02-23
Abstract: PURPOSE: To obtain a generator which does not require the supply of energy from outside and discharges no harmful exhaust. CONSTITUTION: A variable magnetic field source 3, a normal magnetic field source 2, a superconductor 1, and an induction coil 5 are linearly arranged. When the sum of the magnetic fields of the magnetic field sources 2 and 3 is smaller than the critical magnetic field of the superconductor 1, the superconductor 1 shields the magnetic flux owing to the Meissner effect. When the sum of the magnetic fields of the magnetic field sources 2 and 3 becomes larger than the critical magnetic field of the superconductor 1 due to a very small increase in the magnetic field of the variable magnetic field source 3, the Meissner effect becomes ineffective, and the magnetic flux penetrates quickly through the superconductor 1 and the induction coil 5. An electromotive force is induced in the induction coil 5 owing to electromagnetic induction caused by a change in the magnetic field.

Filed: 1994-04-15
Abstract: PURPOSE:To eliminate such data that are extracted only when an error is detected by confirming only true error flag of the byte that includes the highest rank bit of the data which are extracted by the adverse quantization processing. CONSTITUTION:The coded signal received from an input terminal 7 is inputted to a demultiplexer part 8 and separated into the scale factor, the assigned bit number and the spectrum data.

Title: Apparatus for testing semiconductor
Inventor: KAJI NAOTO
IPC: G01R31/26
Filed: 1988-03-29
Abstract: PURPOSE:To shorten waiting time and shorten the time required for measuring a large amount of devices by a method wherein temperature of a device is measured based on voltage between terminals by applying a constant current to a diode housed in the semiconductor device and measurement of a device is started as soon as high temperature or low temperature conditions are reached. CONSTITUTION:When a test is started by a tester 4, a voltage value V1 corresponding to temperature T1 is generated from a line 105 and set in a register 5, a value '1' is output from a line 107 and a value '0' is output from a line 108. While the temperature TJ of the device is >T1, voltage VF between terminals of a diode 9 is >V1, so that a comparator circuit 6 outputs a value '0' from a line 109 and an OR circuit has a value '0', not causing the tester 4 to start. When the device 1 is cooled so that TJ>T1, the circuit 6 outputs a value '1' from the line 109 to start the circuit 8 and the tester 4. This causes a line 101 to output a test signal to carry out a test of the device 1.

Title: Humidity sensing device
Inventor: MOROI YASUHIRO
IPC: G01N27/00
Filed: 1985-04-12
Abstract: PURPOSE:To detect the replacement period of a humidity sensing material by generating a on-off signal by a cleaning heater arranged nearby the humidity sensing material and counting one-shot pulses generated according to the output signal. CONSTITUTION:The humidity sensing material 1 deteriorates in sensitivity owing to the sticking of matte in an atmosphere, so the humidity sensing material 1 is heated by a heater 2 and cleaned. At this time,a cleaning signal generation part 8 generates a on signal for turning on the heater 2. This on signal allows a one-shot pulse, which is counted by a pulse counter 10. Further, the set number of times of heat cleaning which indicates the replacement period of the humidity sensing material 11 is set in a pulse setting part 11. Then, a digital comparator 12 compares the value of the pulse counter 10 with the value of a setting counter 11 and generates a warning 13 of the replacement period of the humidity sensing material 1 when the pulse counter value increases above the set counter value. Thus, the replacement period of the humidity sensing material is detected by the simple circuit constitution.
