Title: Flash fixing device
Inventor: SHIMIZU SUKEZOU
IPC: H05B41/32
Filed: 1983-12-15
Abstract: PURPOSE:To generate a high voltage without using a boosting transformer by connecting plural capacitors in parallel to charge the capacitors, and at the time of discharge, switching said connection in series to emit a flash lamp. CONSTITUTION:A rectifier is connected to a power supply 3 to generate DC. To connect plural capacitors 71-7n in parallel, switches 81-8n are turned to the opposite contacts against the shown ones. The positive pole of the rectifier 3 is connected to anodes of diodes 61-6n to charge the capacitors 71-7n. When alteration switches 81-8n are turned to the shown status by an unshown operation button, the capacitors 71-7n are connected in series and the voltage on both the ends becomes n times the voltage of one capacitor, so that the flash lamp 5 is emitted. Even if the boosting transformer is omitted and the size of the device is reduced, a high voltage is generated.
Patent JP-H0685606-A (JP)
Title: Bias conversion type filter circuit
Inventor: NAKAGIRI KOJI
IPC: H03H11/04
Filed: 1992-09-04
Abstract: PURPOSE:To prevent the output offset caused by the fluctuation of resistance, etc., by providing a voltage/current converter which converters the difference between the input voltage and the reference voltage into a current and a means which supplies the output of the voltage/current converter to the resistance via a filter. CONSTITUTION:The reference voltage Vref of the input voltage Vi is converted into the 2nd reference voltage Vref2 at an output terminal 17. The same voltage level is secured between both input terminals 10 and 11 when voltage Vi includes only a DC component, i, e., Vi = Vref is satisfied. Therefore the difference voltage is equal to zero between both terminals together with a current I1 also set at zero. As a result, no current flows to a resistance R7 and therefore the Vref2 applied to a terminal 16 is led out to the terminal 17 as it is. That is, the output reference voltage is set at the Vref2 owing to a fact that no current flows to the R7. As result, the fluctuation of the R7 and the resistance R7/R5 ratio never affect the reference voltage. In other words, no output offset is produced.

Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To prevent the readhesion of fine particles by electric repulsion by cleaning a variety of electronic parts members in cleaning liquid having negative oxidation-reduction potential, where hydrogen gas is dissolved in ultrapure water. SOLUTION: Hydrogen gas is dissolved with a gas dissolving bath 2 into ultrapure water where dissolved oxygen gas, nitrogen gas, carbon dioxide gas, etc., are degasified with a degasifier 5 so as to make it have oxygen-reduction potential, and the ultrapure water is sent from a supply 13 to a pH adjusting bath 3 to adjust pH, and then it is sent to a cleaning bath 4. Then, the fine particles at the surface of a wafer are cleaned off in cleaning liquid which has negative oxidation-reduction potential by dissolving hydrogen gas in ultrapure water, and it is rinsed in ultrapure water immediately.  Hereby, the fine particles on the surface of a silicon wafer can be removed effectively with lower pH, and a large quantity of ammonium water need not be consumed, and the roughening of the surface of the silicon wafer by alkali can be prevented, and in its turn, the material and the waste solution processing cost can be reduced.

Title: Forward dc/dc converter
Inventor: NISHIMURA KATSUHIKO
IPC: H02M3/28
Filed: 1988-09-21
Abstract: PURPOSE:To improve the power conversion efficiency of a high frequency transformer by taking out the exciting energy for the high frequency transformer at the secondary output. CONSTITUTION:A pulse signal subjected to pulse width control corresponding to the variation of an output voltage E0 is applied onto the base of a switching transistor 10. When the switching transistor 10 is turned OFF, no energy is transmitted from the primary to the secondary and reverse voltage is induced in the windings 11a, 11b, 16 by the exciting energy of a high frequency transformer 11. At this time, current loop through the primary winding 11a is blocked by a transistor 10 while current loop through the secondary winding 11b is blocked by a diode D2, but a current loop is formed through the winding 16 and a diode 17. Consequently, exciting energy for the high frequency transformer 11 flows, in the form of de-energizing current i1, through the current loop of the winding 16 in the direction of an arrow shown on the drawing and transmitted as an output energy to the output terminals 15a, 15b.
