Title: Protection for inverter device
Inventor: SHIYOUDA KAZUO
IPC: H02M7/515
Filed: 1980-06-10
Abstract: PURPOSE:To protect a gate turnoff thyristor (GTO) from an overcurrent by a method wherein an overcurrent protecting thyristor is turned on by a DC reactor and an overcurrent detection, and a power inverting section is turned off. CONSTITUTION:When a short-circuit is generated at the power inverting section 2, this short-circuit current is suppressed by the DC reactor 20a, the short-circuit current is also detectd by an overcurrent detecting circuit 4, a circuit breaker 19 is broken by the operation of a controlling circuit 5 and an overcurrent protecting circuit 7, and at the same time, the short-circuit current is branched off by the turn on of overcurrent protecting thyristor 13 and the flowing in of the short-circuit  current to the GTO on the power inverting section 2 is reduced. Besides, a gate  turnoff signal is supplied to all the GTO's on the power inverting section 2 by the  controlling circuit 5 and the power inverting section 2 is turned off. Thus, the GTO's are protected safely and securely and the miniaturized and light-weighted  GTO invertor device can be obtained.

Title: Apparatus for controlling operation of secondary throttle valve of two-barrel carburetor
Inventor: TAKAHASHI ATSUSHI
IPC: F02M11/02
Filed: 1983-05-07
Abstract: PURPOSE:To prevent premature opening of a secondary valve of a carburetor used in an engine having a valve for selecting use of heated intake air or cool intake air, by lowering the negative pressure at which the secondary valve is to be actuated at the time of heating intake air. CONSTITUTION:When the engine temperature is low, a valve 18 for selecting use of intake air heated by an exhaust pipe 5 or the atmosphere closes a temperature-sensitive valve 25 and transmits the negative pressure in a manifold to a diaphragm 19 via a port 24, an orifice 26 and a pipe 21, so that the valve 18 is shifted to the position for using heated intake air. Negative pressure in the pipe 21 is transmitted also to a diaphragm 30 and opens a valve 31, so that a pipe 27 is released to the atmosphere and atmospheric air is introduced into a first passage 14 via an orifice 34. Although negative pressure is acted in a port 8 when a primary throttle valve 10 of a carburetor is opened, a secondary throttle valve 11 is not opened since the negative pressure is weakened by the atmospheric air. With such an arrangement, it is enabled to prevent premature opening of the secondary throttle valve due to the high negative pressure ratio caused at an intake-air heating section by the resistance to the intake-air flow.

Title: Electronic tuning oscillator
Inventor: NISHIDA HARUKI
IPC: H03B5/18
Filed: 1986-04-07
Abstract: PURPOSE:To eliminate the need for the adjustment of the modulation sensitivity in changing the oscillation frequency over a wide band by fixing a sub resonance circuit to a position where the ratio of a main resonance frequency and a sub resonance frequency is nearly made constant in using a dielectric part fixed to a frequency adjusting screw so as to change a main resonance frequency of a dielectric resonator. CONSTITUTION:In locating the 2nd transmission line 19 near the dielectric resonator 1, when the dielectric 18 approaches the dielectric resonator 1 and the main resonance frequency is lowered, since the dielectric 18 also approaches the 2nd transmission line 19, the length of the line is prolonged equivalently by the effect of the dielectric constant of the dielectric 18 and the sub resonance frequency is lowered. Then the size, dielectric constant of the dielectric 18 and the position of the 2nd transmission line are selected. Thus, the change in the modulation sensitivity in varying the main resonance frequency only is prevented and the adjustment is not required.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To enable a device to output a rectangular wave containing prescribed high/low voltage without using an operational amplifier, by switching an output voltage range synchronized with switching of duty ratio, when the duty ratio of a pulse signal is switched. SOLUTION: A signal dividing output voltage Vout of an output terminal 12 is inputted to an A/D converter 22 of a CPU 20, it generates a PWM signal of prescribed duty ratio on a pulse width modulation circuit output from a PWM signal output 24.

Title: Starter device for gas equipment
Inventor: HATA KENJI
IPC: F23N5/20
Filed: 1989-03-30
Abstract: PURPOSE:To prevent a useless consumption of a primary cell by a method wherein an energization time control means is provided for setting an energization time increased in response to a reduction in voltage of a primary cell and for terminating an energization from the primary cell to a pushing solenoid after elapsing of this energization time. CONSTITUTION:Under a new state of a primary cell 20, i.e. a state in which a voltage shows a high value, an energization time for a pushing solenoid L1 through an energization time control means 30 is short. However, since an applied current shows a high value, a normal-closed solenoid valve 13 is once completely opened. Under a state in which the primary cell 20 is consumed and its voltage is decreased, the control means 30 may increase an energization time for the solenoid L1. Although the applied current for the solenoid L1 is low, the valve 13 is once completely opened. In any case, after completion of the energization, a suction force caused by the solenoid L1 is diminished. However, the solenoid valve 13 is kept at its opened state through a holding solenoid including a holding solenoid L3 operated through an electromotive force of a thermocouple 27. That is, a useless power consumption for use in opening the valve 13 is eliminated.

Title: Junction type field effect transistor
Inventor: MATSUURA AKIRA
IPC: H01L29/808
Filed: 1982-05-14
Abstract: PURPOSE:To prevent the destruction of the gate of a J-FET having a double ion implantation structure, by making impurity concentration in a top gate layer higher than that in the side of a drain, and forming the end part of a conductor gate at a part inner than the junction part between the top gate layer and a drain layer. CONSTITUTION:The thickness of an oxide film 5 of a gate part is about 1,100Angstrom , and its breakdown voltage is about 70-80V. When the voltage higher than said voltage is inputted, breakdown energy can be absorbed by reducing the breakdown voltage of the P-N junction between a top gate and a drain to the value smaller than the breakdown voltage of the oxide film 5 between a gate Al layer 7 for channel part stabilization and a drain N<+> diffused layer 3. For this purpose, the impurity concentration in a top gate P layer is made to be higher than the concentration in an N layer on the drain side. Thus the breakdown of the oxide film 5 can be prevented. For example, when the impurity concentration in a P<-> substrate is 5X10<15> atoms/cm<3>, the concentration in a channel N layer 4 and a drain N layer 3a is made to be 1X10<17> atoms/cm<3> and the concentration in the top gate P layer 5 is made to be 2X10<17> atoms/cm<3>.
