Title: Temperature detecting method using heat-sensitive thyristor
Inventor: SOGOU TOSHIO
IPC: G01K7/00
Filed: 1978-11-27
Abstract: PURPOSE: To make broad-range temperature detection possible by using one heat- sensitive thyristor by changing gate voltages of the heat-sensitive thyristor by changging resistances over.  
     CONSTITUTION: Resistance 4 of the largest impedance is connected to heat-sensitive thyristor 3 of an n-type, etc., through switch 8 and applying a gate voltage makes thyristor 3, applied with alternating-current power from alternating-current power supply 1, turns ON when reaching a switching temperature. Thyristor 3 turns ON at a phase angle of the lower alternating voltage the higher the temperatue is, and peak voltmeter 9 detecting a peak voltage between the anode and cathode of thyristor 3 detects a temperature of a fixed range. When resistance 5 lower in impedance than resistance 4 is selected, the heat sensitive characteristic of thyrestor 3 varies and a high temperature of the fixed range is detected, so that the temperatue detection range will further widen through resistances 6 and 7. Therefore, the broad-range temperature detection can be done by using one thyristor.

Title: Sensor circuit
Inventor: HIRAKATA NOBUYUKI
IPC: H03F3/34
Filed: 1990-06-05
Abstract: PURPOSE:To obtain the circuit which is tolerant to high-temperature environment and not affected by an offset voltage by switching characteristics of a differential amplifier circuit in synchronism with the polarity switching of the output voltage of a sensor means, and amplifying the output voltage while holding the same polarity. CONSTITUTION:Switch means 15 and 18 invert and switch the polarity of the voltage between two input terminals with the switching control signal from a terminal 19 and output the voltage, and the polarity is not inverted when the switch means are at 1st positions (Pt), but inverted when at 2nd positions Pt. Therefore, when the switches 15 and 18 are at the 1st Pts, the output characteristic of the differential amplifier circuit 12 viewed from a Hall element 14 is as shown in a figure (A) and when at the 2nd Pts, the output characteristics are as shown in a figure (C); and the two characteristic curves 25 and 27 have the same gradient, but the polarity of an offset voltage DELTA is inverted. Therefore, the output voltage of the circuit 12 at this time has a waveform which has AVH in the center (A: gain, VH: output voltage of element 14) and an amplitude 2ADELTAV. The output voltage of the circuit 12 is therefore a time-averaged DC component after noise components are removed 13a and 13b, i.e. voltage AVH without offset voltage.

Abstract: PURPOSE: To obtain an FET on sapphire simply and at a high yield ratio by making Si layers thickness thin for source and drain, and thick for gate, respectively.  
     CONSTITUTION: n-Type Si island 2 having [100] face is formed on sapphire 1, which is overlaid with SiO 2  film 3 and polycrystalline Si film 4. After covering the film 4 with SiO 2  film and Si 3 N 4  film 5, the surface is further covered with SiO 2  film.

Next, hydrazine hydrate is used at about 60°C for anisotropic etching to permit the film 4 to be etched from both sides and the film 2 to be etched to form a trapezoid. The film 5 is removed and phosphorus ions are injected into the films 4, 7, 8. This is followed by head treatment to permit the ions to be penetrated reaching the sapphire surface and at the same time ions be going to the lower part of the film 4 under the gate oxide film 3. Thereafter, SiO 2  film 9 is deposited and Al electrode is selectively formed to complete the device.

Title: Feeder in powder molding equipment

IPC: B28B3/02
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To uniform the density of a green compact by providing a preparation member of the feed quantity of the raw material powder provided in the longitudinal direction of an opening part in a feeder body. SOLUTION: A feeder body 13 is moved straight in the longitudinal direction by a drive mechanism. A plurality of wires 18 which are preparation members are stretched in a center part in the longitudinal moving direction of the feeder body 13. The raw material powder from a tip opening part of a feed pipe 15 is impeded by the wires 18. The opening area of a lower opening part 13A in a cylindrical cavity is left unchanged on the right and left sides due to absence of the wires 18 with the longitudinal direction of the feeder body 13 as a reference, while the opening area is shut off by the part of the wire 18 in the longitudinal direction and reduced. That means, the difference between the right and left sides can be reduced. Thus, the filling density of the raw material powder can be unified.

Abstract: PURPOSE:To eliminate uncomfortable feeling of electromagnetic noise by control ling acceleration/deceleration of an electric vehicle such that the switching frequency will have specific rhythm with respect to the time. CONSTITUTION:Switching frequency of an inverter can be set independently from inverter frequency within a range in asynchronous control region being limited by a system.

In other words, when the switching frequency is outputted in the form of a function of inverter frequency under constant variation rate of inverter frequency, 264, 293, 330Hz are set to a rhythm of do, re, mi, do, re, mi. Furthermore, switching frequencies 264, 294, 330Hz are outputted in the form of a time function having a rhythm of do, re, mi, do, re, mi.

IPC: F16K51/02
Filed: 1982-08-27
Abstract: PURPOSE:To adjust the pressure in a vacuum tank automatically and finely to a desired value by providing a constant throttle at the intake side of the vacuum tank and adjusting the discharge side with a variable-conductance valve having a special shape. CONSTITUTION:A variable-leak valve 5 set to allow gas of a constant quantity to flow into a tank from a gas cylinder 4 is connected to the intake side pipe of a vacuum tank 1, and a variable-conductance valve 6 as a discharge valve and a vacuum pump 2 are connected to the discharge side pipe. When the piston valve 13 of the variable valve 6 retreats from a valve seat by means of a drive motor, the cross-sectional area of a key-type passage (a1, a2, a3) formed by the conical piston peripheral surface and the cone-shaped surface of the valve seat tends to increase gradually. It was found that the gas flow through such a fluid passage was nearly proportional to the piston displacement within a certain range of the piston stroke. Therefore, the degree of vacuum in the vacuum tank 1 can be automatically adjusted and maintained at a desired value by finaly adjusting the displacement quantity of the piston by means of the PID control of the drive motor.
