Filed: 1989-03-28
Abstract: PURPOSE:To reduce a power MOSFET drain-source capacity by providing below a source pad an impurity diffusion layer having a different conductivity type as that of a source part and making the impurity diffusion layer and the source part of the same potential. CONSTITUTION:An impurity diffusion layer 7 of a different conductivity type from that of a source 1 is formed below a source pad 5 and is made the same potential as that of the source part 1. Accordingly, capacity between the source pad 5 and a drain part 2 provides depletion layer capacity formed by the impurity diffusion layer 7 below the source pad 5 and by a drain part 2, which is smaller than oxide film capacity below a conventional source pad 5. More specifically, as breakdown strength between the source and the drain is increased and impurity concentration in a semiconductor substrate is reduced, the width of a depletion layer established by the impurity diffusion layer 7 below the source pad 5 is spreaded, and the depletion layer capacity is reduced compared with the oxide film capacity below the conventional source pad 5. Hereby, the source-drain capacity is reduced.

Title: Solenoid drive system
Inventor: WATANABE KENICHI
IPC: H01H47/04
Filed: 1978-06-23
Abstract: PURPOSE: To inhibit crashing sounds and mechanical vibration in case of functioning, by limiting currents at a moment when a solenoid starts its action, and by letting overcurrents flow after delay time.  
     CONSTITUTION: Currents are differentiated by means of a differentiation circuit A 1  at a moment when an input terminal T becomes to high voltage, polarity is inverted and a transistor TrQ 1  is conducted only for a fixed time. A TrQ 2  is under a conductive condition during the time when the input terminal T is in high voltage. Meanwhile, a TrQ 3  does not become to a conductive condition owing to a retardation element A 2  for a while after the T reaches high voltage. Thus, currents from power sources +B 1 , +B 2  pass through a solenoid SOL and flow through the TrQ 2 , but the currents do not flow up to the maximum value of overcurrents because they are limited by means of a resistance R4. When the output of the retardation element A 2  also reaches high voltage, currents flowing through the SOL also flows through the TrQ 3  because the TrQ 3  also becomes to a conductive condition. Consequently, the maximum currents of overcurrents from the power source +B 1  flow through the SOL, and the SOL positively functions.

Title: Combustion safety device
Inventor: TANAKA EIICHI
IPC: F23N5/24
Filed: 1979-06-15
Abstract: PURPOSE:To prevent imperfect combustion and secure safety by a method wherein an oxygen partial-pressure sensor is fitted on the downstream side of the flame of a burner so as to detect the fuel/air mixing ratio. CONSTITUTION:Spreading of flame to a main burner 2 is effected from the flame F1 of a pilot burner 6, thereby forming a flame F2 and conducting normal combustion. In the normal combustion condition, the temperature of an oxygen partial- pressure sensor 8 placed under the fin portion 4 of a heat exchanger 3 rises. Since the electric resistance of the sensor 8 changes with the fuel/air mixing ratio, the fuel/air mixing ratio is determined through the detection of the electric resistance of the sensor 8 by an electronic circuit 9 and when the mixing ratio is improper, a solenoid valve 10 is closed to cut off the supply of fuel for the nozzle 11 of the main burner 2. Accordingly, combustion is stopped when the oxygen amount is smaller than that required for perfect combustion of the flame, thereby securing safety.

Filed: 1988-03-31
Abstract: PURPOSE:To facilitate improvements in a deep notch and cutting speed and a reduction in chips, by a method wherein a ring forming a cutting edge is supported turnably by a guide wheel provided on the external circumference of a frame and a driving part such as a bevel gear is arranged on one side of the ring. CONSTITUTION:When a bevel gear 9 is turned by a motor, a ring 3 to which a gear 10, with which the bevel gear 9 gears, is provided is turned under a state where it is supported by a guide wheel 5 of a frame 2 arranged on the inside of the ring 3 and cogs on the external circumference of the ring 3 are turned. When a rotating ring 3 is pressed away to a work to be cut by pressing the frame 2 downward, the work to be cut is cut off with the cogs of the ring 3; but since a driving member such as the motor is provided on the upper part of the ring 3 and the central part of the ring 3 is free from a projection, the ring 3 is insertable deeply into the work to be cut. Then although the driving member such as the motor is arranged on one side of a ring saw, the projection disappears from the opposite side; therefore, the work to be cut can be cut off by moving the ring saw along a side of a wall.
