Filed: 1992-06-10
Abstract: PURPOSE:To improve the throughput for correction of a short circuit by executing continuous etching of the respective layers of multilayered films by using a mask for exposing superposed with the respective layers of multilayered structure patterns. CONSTITUTION:Patterns 24 for correction are formed by superposing the two- layered structure patterns on each other and are designed to the size larger by <=10mum, for example, 2mum than the size of the actually superposed patterns. The margins of exposing, developing and etching processes are, therefore, taken. A PR(photoresist) treatment is executed in order of exposing  developing  etching (conductive film A220)  etching (conductive film B23) by using the patterned 25 mask for correction to remove the residuum 24 of the conductive film A which is heretofore the cause for a short circuit. The residuum 26 of the conductive film B which is the cause for the short circuit thus is similarly removed by executing the same PR treatment in the same order by using the patterned 25 mask for correction even if the residuum 26 of the left side conductive film B is connected and shorted to the right side conductive film B23 by the etching defect of the conductive film B23.

Title: Power unit for discharge lamp
Inventor: MORI SHIGEHISA
IPC: H05B41/28
Filed: 1992-06-10
Abstract: PURPOSE: To increase a power factor, and weaken higher order harmonics by increasing the matching of input end inductive and capacitive impedance, minimizing higher order harmonic components generated in a circuit, and simultaneously improving an input end current waveform so as to be close to a sine wave. CONSTITUTION: By lessening the capacity of a capacitor 4, the conduction time of rectifying diodes 31 to 34 can be shortened so that a power factor can be increased. A voltage after rectification is always higher than a certain value by the mutual action of an inductor 1 and capacitors 2, 4, 7. The voltage waveform of the capacitor 4 is larger than zero, but changes. The same is applied to the output portion 5 of an oscillator and the capacitor 7, and is fed to an inductor 6 and a fluorescent lamp FL. This time, an input current waveform is close to a sine wave, higher order harmonic components are reduced, and further the output voltage envelope of the output portion 5 is always positive. Thereby, damage resulting from a harmonic current flowing to a power supply circuit can be prevented in a rectifier 3.

Abstract: PURPOSE:To improve the machining performance by arranging the transmission type polarized reflection plate to form a blue star angle for an incident laser light between a polarizer and laser oscillator. CONSTITUTION:A transmission type polarized reflection plate 15 is set up between a laser oscillator 10 and 90 deg. phase delay type total reflection mirror 12 so that the laser light 11 emitted from a laser oscillator is made incident at a blue star angle thetaB on the reflection plate 15 and the reflection plate normal line and polarized face become the same plane L. The transmission factor of the reflection plate 15 is set so that the laser light 11 may transmit with no reflection approximately. In case of the reflection factor of the body 14 to be worked being high a reflected circularly light wave receives a 180 deg. phase variation at the reflection time and a 90 deg. phase difference is caused by the reflection mirror 12 further. The circularly polarized light wave is therefore made incident on the reflection plate 15 with its P wave becoming an S wave an d reflected to the direction of an absorbing body 16. The laser beam machining performance is improved because of the accident, etc., of the oscillator being prevented.
