Title: Cooling device for electronic part
Inventor: HIRASAWA SHIGEKI
IPC: H01L23/427
Filed: 1983-12-26
Abstract: PURPOSE:To enable to cool a chip in such a manner that its surface will be brought to uniform temperature even when heating power becomes larger by a method wherein a device, to be used to guide a volatile liquid sent from the inner wall of an airtight container by capillary action and the like, provided on the back side of each chip. CONSTITUTION:The heat generated by semiconductor chip 2 is transferred to the fine groove 9 located on the back side of the semiconductor chips, and the liquid in the groove 9 is evaporated by the heat. The steam generated at this time passes through the space in the steam located in the airtight container 4 and moved to the side of a condensation surface. As the circumference of the condensation surface 7 is cooled by a cooling jacket 6, the steam is condensed and formed into a liquid. The generated liquid is absorbed into a groove 8, then it flows in the groove 8 and a capillary tube 10 by the help of capillary action, returns to the fine groove 9 located on the back side of the semiconductor chip, and the same cycle as above is repeated. Thus, the evaporation and cooling of liquid is performed on the back side of the chip 2, and the chip is not overheated when the operation of the cooling device is started. Also, the liquid can be supplied irrespective of the density of chips even when the chips 2 are densely mounted on the substrate 1.

Filed: 1983-12-28
Abstract: PURPOSE:To obtain an individual selective call receiver by handling a message signal and an address signal with the same code so as to suppress the increase in the scale of hardware and the decrease in the subscriber capacity to a small value. CONSTITUTION:The signal architecture as shown in Fig. is considered as a selective call signal with message, where ''S'' is address information and D1, D2 indicate message information.

This is because the signal detecting processing is unified and the scale of the detector is decreased by adopting a common code. The message signal consists of the BCH (31, 21) being one of a cyclic code by the same code as that of the address signal and the numeric information is handled by a pure binary code, then plural bits produced by being handled with the BCD code are used for other functions, thereby utilizing time effectively.

Filed: 1994-10-12
Abstract: PURPOSE: To obtain a power semiconductor device in which fluctuation can be suppressed in the characteristics or impedance of individual chip without causing useless increase of power consumption or without operating the device with a current lower than a rated value. CONSTITUTION: Currents proportional to those flowing through the current paths of a plurality of IGBTs Q11 , Q12 ,...

Title: Multiple detector of electron
Inventor: SEKINE SATORU
IPC: H01J49/44
Filed: 1996-09-18
Abstract: PROBLEM TO BE SOLVED: To perform conduction of a high voltage of a single system into a vacuum and provide an optimum operating voltage for respective channel-tron by providing a bias resistance having a variable resistance value corresponding to each channel-tron. SOLUTION: A channel-tron 8 and a resistance R of the channel-tron itself, bias resistances R1 and R2 , and a coupling capacitor C1 constitutes a circuit of a single system channel-tron. In this case, an applied voltage to the channel- tron 8 is determined by a supply voltage HV, the resistance R2 , and the resistance R. By changing a bias resistance R'2 using a variable resistor, even if the voltage HV is constant, a voltage between both ends of the channel-tron can be changed. Consequently, when a mechanism for changing the bias resistance is thus provided for each channel, an operating voltage can be changed every individual channel-tron; therefore, a stray capacitance is reduced, and an operating voltage value can be applied to individual channel-trons with fast response and high wave-peak.
