Title: Forced air cooling device
Inventor: HAYASHI ISATAKA
IPC: F25D1/00
Filed: 1994-07-18
Abstract: PURPOSE:To prevent an eddy air flow from being produced and improve the cooling efficiency by a method wherein a flow regulating plate crossing at a right angle with an air suction plane is mounted just before the air suction plate. CONSTITUTION:A table 2 is fixed to a frame 1. Many electronic circuit devices 8 are loaded on the table 2. A flat plate flow regulating plate 10 is mounted in such a manner that it may be crossed at a right angle just before the suction plane of a blower 6 so as to prevent air sucked into a side surface of a vane wheel 7 from becoming an eddy air flow. With such an arrangement as mentioned above, the cooling capability obtained from the blower 6 is made most appropriate one. Even if a sufficient distance (1) is not kept between the air sucking plane of the blower 6 and a wall surface 5, the electronic circuit device 8 can be efficiently cooled. In addition, if an improved efficiency of the blower 6 caused by mounting of the flow regulating plate 10 and an increased amount of pressure loss caused by a shortage of the distance (1) are properly balanced, a width of the blower 6 and a width of the table 2 can be reduced without cooling the electronic circuit device 8 having a larger amount of heating with the blower 6 of the same size or reducing a cooling capability and then the electronic device can be miniaturized.

Title: Peak detecting circuit
Inventor: HAMADA YUUICHIROU
IPC: G11B27/22
Filed: 1979-12-19
Abstract: PURPOSE: To prevent malfunction owing to the dispersion in the S/N of input signals by controlling any of the time constant, gain and DC level of an integrator.  
     CONSTITUTION: When the negative supply voltage applied to an operational amplifier 25 is defined as ±V cc , the detection pulses fetched at an output terminal 24 become the negative pulses falling to ++V cc W-V cc . Integration time constant may be changed by changing the value of a variable resistor 26a and if the value thereof is increased, the waveform changed to the gentle slope may be formed. If the S/N of the output signal of a phototransistor 12 is good, or when S/N is made  the same, the resistance value of the variable resistor 26a is higher as the signal  width is smaller. In this way, the malfunction owing to the dispersion in the S/N of  the input signals is prevented.

IPC: H01L21/8246
Filed: 1978-12-30
Abstract: PURPOSE: To achieve high integration by making it possible to form channel cut regions of different channel cut concentrations.  
     CONSTITUTION: Oxide film 22 and silicon nitride film 23 are formed on substrate 21, and the entire portion is window-opened wherein channel cut regions are to be formed through proper mask, and then ion injection is operated for low concentration channel cut.

In the part not requiring high concentration channel cut, it is possible to maintain a high breakdown voltage in the junction between the source-drain region and the channel cut region. In the part requiring high concentration channel cut, a high breakdown voltage can be maintained by some other means, for example, the use of a pattern margin. Thus, high integration can be achieved.

Filed: 1982-09-25
Abstract: PURPOSE:To reduce the rush current when a heater is switched on by turning on the heater in the predetermined duty ratio at all times and controlling the rate of temperature reduction at heat power supply OFF. CONSTITUTION:When a power supply of a copying machine is applied, a control section 1 turns on a signal S1 until the surface temperature of a roll 1 reaches a preset value, and then turns it off and a control section 12 outputs a signal S2 having a predetermined duty ratio. Thus, a heater control relay 13 closes a heater circuit 10 when the signal S1 or S2 is turned on to apply a current to a heater 7. Thus, even if the control section 11 is turned off, the heater 7 is heated at a prescribed period with an output signal S2 of the control section 12 to decrease the temperature decrease of the heater itself due to the natural cooling of the heater 7.

Title: Accumulator of frictional engagement device of automatic speed change gear for car
Inventor: KATO EIJI
IPC: F16H61/10
Filed: 1984-08-09
Abstract: PURPOSE:To prevent a speed change shock by setting the pressure for urging to the first position lower than the pressure for the completion of urging of return urging means when a piston of an accumulator is located at the first position, and oil pressure applied to back pressure urging means is low. CONSTITUTION:In an accumulator 590 of an automatic speed change gear, when an accumulator piston 596 is located at the first position, and oil pressure applied to the back pressure urging means 598b is low, the pressure for urging to the first position is set lower than the pressure for the urging completion of a spring 598a which is the first urging means. Accordingly, only when the piston 596 is located between the first position and a position changing to the second position side, the piston is urged to the second position by a spring 599 which is the second urging means. Thus, as an accumulator piston 2 is started for engagement of a clutch when oil pressure applied to back pressure urging means is low, a speed change shock can be reduced.
