Title: Switching power supply
Inventor: OTAKE TETSUSHI
IPC: H02M3/155
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To obtain high efficiency for a wide range of input voltage in a voltageup/down switching power supply especially by improving the efficiency at low input voltage. SOLUTION: A first rectifying circuit 4 and a second rectifying circuit 5 are placed by parallel connection between the connecting point (a) between a choke coil L1 and a switching transistor Q1, and an output terminal 2 in order to cause a power circuit to increase and decrease voltage. The first rectifying circuit 4 is composed of a coupling capacitor C3, an auxiliary inductance L2 and a rectifier diode D1, and the second rectifying circuit 5 is composed mainly of a transistor Q2, a transistor Q3 for drive and a capacitor C4. The first rectifying circuit 4 becomes automatically active or inactive depending on whether the second rectifying circuit 5 is active or inactive.  Therefore, a rectifying circuit for use in power transmission from the input side to the output side is selected by adjusting a transistor Q4 as an auxiliary switch to bring the second rectifying circuit 5 in an active state or in an inactive state.

Abstract: PURPOSE:To discharge the inflated gas in the cell at the brazing, by providing a recess in the ring conducting from the interior to the exterior when brazing the ceramic ring and the seal board through the brazing material after the insertion of the generating element. CONSTITUTION:The metal galvanized layer is formed on the seal boards 6, 7 to be used as the negative and positive terminal boards while the metalized layer and the metal galvanized layer are formed on the ceramic ring 5. Then the brazing material 9 is arranged at the circumference of the seal board 7 and the ring 5 is mounted to be pressurized and heated to perform the soldering, then after inserting the generating element 1 the seal board 6 is mounted through the brazing material 8 on the recess 5a provided at the portion of the ring 5 conducting from the interior to the exterior to be pressurized and heated to perform the brazing. Consequently the inflated gas in the cell can be discharged through the recess 5a thereby the through-hole is never made in the brazing material and the brazing material is never jutted out.

Title: Electronic device
Inventor: KOIZUMI SHIGERU
IPC: H05K7/20
Filed: 1987-06-15
Abstract: PURPOSE:To control cooling air quantities according to heating values and make the effect of cooling uniform by making mounting intervals of devices having the great heating values large and by providing cooling air guiding members in a structure having electronic devices for cooling a plurality of printed circuit substrates. CONSTITUTION:Cooling air quantities being blown toward cooling air flow paths in a package 4 which highly generates heat increase in comparison with those in the packages 5 which generate low heat by making mounting intervals of the package 4 generating highly heat larger than those of the packages 5 generating low heat and the resulting cooling air cools each package at a uniform temperature. Since cooling air guiding plates 8 have cross sectional forms which are thin at the intake side and increase their thicknesses continuously in the direction of the exhaust air side, the speed of cooling air becomes greater as it approaches the exhaust air side and the resultant temperatures at elements equipped in the package 4 become uniform. And then, blast pressure loss is so small that this device makes it possible to have a small, low noise blower.

Title: Buffer circuit
Inventor: NAGANUMA MASAYUKI
IPC: H03K19/00
Filed: 1986-06-25
Abstract: PURPOSE:To build a circuit capable of an adequate supply of currents under a heavy load with noise voltages suppressed low by a method wherein time constant circuits are provided in a buffer front stage and the time length for a buffer to be turned on is subject to the time constant when a switch control signal is changed over in its polarity for the turning-on of the buffer. CONSTITUTION:Time constant circuits 61 and 62 are connected between an input terminal 1 and buffer 7, and the buffer 7 is turned on after the passage of time from the inversion of a switch control signal (a), with the length of the time corresponding to the time constant provided by the time constant circuits 61 and 62. This design enables a MOSFET with a great driving capability to be used as the buffer 7, which means a lowered resistance to the output of the buffer 7. This also means that there will be no increase in the output terminal voltage when the buffer 7 is turned on under a heavy load, which ensures an adequate supply of currents. Noise voltages will be kept low because of the time constant governing the time the buffer 7 requires before it is turned on when the polarity is changed over of the switch control signal (a).
