Patent JP-S61214576-A (JP)
Title: Semiconductor device
Inventor: KOMORI KAZUHIRO
IPC: H01L29/78
Filed: 1985-03-20
Abstract: PURPOSE:To protect internal circuits from electrostatic breakdown by a method wherein a source region and a drain region of a parasitic MIS element are composed of respective high density semiconductor regions and respective low density regions surrounding them and the high density regions are offset against a gate electrode. CONSTITUTION:A field insulation film 2 is formed on a surface of a P-type semiconductor substrate 1 and a gate electrode 15 is formed on the film 2. A source region and a drain region of a parasitic MIS element are constituted by N<+> type regions 18 and 19 formed at the same time with a source region and a drain region of an N-type MOSFET using the field insulation film 2 as a mask and N<-> type semiconductor regions 16 and 17 formed below the N<+> type regions 18 and 19 surrounding them respectively. The regions 16 and 17 are so formed as to overlap with the end parts of the electrode 15. As the electrode 15 is formed on the thick insulation film 2 only, this parasitic MOSFET has a high dielectric strength and electrical breakdown of the gate insulation film 2 is avoided.

IPC: H04M3/30
Filed: 1986-03-14
Abstract: PURPOSE:To reduce remarkably the operating time and to reduce the number of maintenance personnels by providing a pseudo outgoing trunk equipment to a terminal equipment side and detecting a fault of a subscriber line through pseudo outgoing. CONSTITUTION:When power is applied, a relay 531 is operated, a contact 531d is closed to form a channel as a loop. In detecting it by a subscriber line 6, an outgoing register trunk 7 detects the loop and sends a dial tone of 400Hz to a channel. The dial tone is detected by a signal tone detection circuit 54 and the signal is sent to an alarm circuit 55, then a clock circuit 552 is driven by a ground level from a contact 531c, the signal is synchronized with an output signal and no alarm is raised. When no dial tone is given, the tone is not detected by the circuit 54. Thus, the signal is not synchronized with the output signal of the circuit 552. In confirming it, the information is obtained and a relay circuit 551 is operated. An alarm display lamp 553 is lighted by the closing of the contact 551a. Further, an alarm display buzzer 554 is rung by the closing of the contact 551b.

IPC: H01F6/00
Filed: 1978-05-09
Abstract: PURPOSE:To ensure an effective excitation for the large-current superconductive coil by giving an  alternate conduction and heating to the heaters which are provided to plural number of superconductive wires featuring the high critical magnetic field and large critical current and then  enclosing the magnetic fields sequentially to secure the pumping function. CONSTITUTION:When conduction and heating is applied to heater 14 with the normal conduction  given to superconductive wire 11, the magnetic field is led to superconductive circuit A formed  with superconductive wires 11 and 12. With discontinuation of conduction for heater 14, wire 11  is turned superconductive again and the magnetic field is enclosed into circuit A. Thus, the  current corresponding to the magnetic flux amount of the magnetic field enclosed flows to circuit  A. Then when the conduction and heating is given to heater 15 with the normal conduction  secured to wire 12, the current of circuit A flows to superconductive circuit B containing superconductive coil 13. With conduction stopped to heater 15, wire 12 is turned conductive again and  the current flows to the superconductive circuit comprising wires 11 and 12 plus coil 13. Thus,  coil 13 is excited. In this way, the pumping function is obtained by applying he conduction and  heating to heaters 14 and 15 and enclosing the magnetic fields in sequnce, thus obtaining the fixed  excitation at coil 13.

CONSTITUTION:A refrigerant intermittently flows into a suction pipe 16 through a suction pipe 15 by reciprocating motion of a piston 5. When a cylinder 8 is placed in a suction stroke, suction gas, left as it is, flows into the cylinder 8, but when it is transferred to a compression stroke by ending the suction stroke, the suction gas, because of its inertia force, continues to flow in the suction pipe 16 for a short time. Here are provider communication holes 16a, 16b, 16c in the suction pipe 16, and the suction gas partly flows out into a closed case 2 from these communication holes. Each communication hole, whose opening hole position, quantity and hole size are matched with a noise frequency, effectively reduces a noise. A sleeve 17 having fine space holes 18 is provided by covering this opening hole, to further reduce the noise by suppressing a pulsation of gas.

IPC: H04B7/015
Filed: 1979-05-04
Abstract: PURPOSE:To enable to operate the amplifier with greater output, by equalizing the phase rotation of input signal through the input of the input signal to the envelope detector and of the specified function obtained from the output to the function generator, to the phase modulator. CONSTITUTION:The equalized signal input to the terminal 201 is input to the phase moldulator 202 and the envelope detector 203. The detector 203 detects the envelope of the amplitude modulation AM component and feeds it to the function generator 204. The generator 204 produces the function representing the relation between the input amplitude and phase rotation and this is fed to the modulation signal input terminal. The modulator 202 performs phase modulation PM for the input signal with the function from the generator 204 and outputs the signal eliminating the phase rotation component included in the input signal, to the terminal 205. Thus, the distortion due to AM-PM conversion of the non-linear type amplifier is equalized and the amplifier can be operated with greater output.

IPC: G01M11/00
Filed: 1986-03-12
Abstract: PURPOSE:To perform accurate monitoring operation and to improve measurement accuracy by changing the traveling direction of at least pat of laser beam emitted by a light source. CONSTITUTION:A diffraction grating 10 which has no polarization characteristics is arranged in a specific direction on the optical path connecting the laser 1 and a photodetector 3. Then, a part of the laser beam L0 emitted by the laser 1 is transmitted through the grating 10 to obtain transmitted light L3, and the remainder is diffracted by the grating 10 in a fixed direction to obtain diffracted light L4. For the purpose, the transmitted light L3 is guided as monitor light to the photodetector 3 and the diffracted light L4 is guided as measurement light to a body to be measured. The grating 10 is not affected by the plane of polarization of the laser beam L0, so the ratio of the quantity of light between the transmitted light L3 and diffracted light L4 is always constant regardless of variation of the plane of polarization. Namely, if the quantity of the measurement light (diffracted light L4) varies according to variation in the quantity of the laser beam L0, a variation quantity corresponding to the quantity of the variation accurately appears in the monitor light (transmitted light L3), so accurate monitoring is possible.
