Abstract: PURPOSE:To obtain a stable single crystal silicon thin film including less grain boundary and crystal defects, by providing a beam forming means, combining a convex lens and a group of a plurality of convex lenses arranged in parallel with the optical path, in the optical path of a parallel laser beam. CONSTITUTION:A beam forming mans 3 is provided in the laser beam path 4 between a laser source 1 and a sample 5 to control distribution of laser beam intensity. The means 3 is formed by a first optical means 7 consisting of a cnovex lens and a second optical means 8 formed by arranging a plurality of convex lenses 81-87 within the laser beam path. Thereby, distribution of laser beam intensity irradiating the sample 5 becomes almost uniform within a circle in the diameter of 50-300 mum. Even if the initial distribution of laser beam intensity is deviated from the Gaussian distribution, deviation of intensity distribution of beam irradiating the sample 5 becomes small. Thereby, stable single crystal silicon thin film having less grain boundary and crystal defects can be obtained.

IPC: G11C16/06
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To protect a switch from break by an overcurrent when a write voltage to a flash ROM obtained via the switch is shortcircuited. SOLUTION: When +12V from a feed power source 11 is impressed to a flash ROM as a write voltage Vpp via an FET 7, if Vpp-E is shortcircuited, a light-emitting element in a photocoupler 8 is turned to a state to emit light, and therefore the +12V from the feed power source 11 is impressed to a gate G of the FET 7 via the photocoupler 8. As a result, the +12V from the feed power source 11 is prohibited from being impressed to the flash ROM via the FET 7.

Title: Image forming device and its adjusting method
Inventor: YUGE KEIJI
IPC: G03G15/16
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent toner or carrier from adhering to an image carrier and to eliminate the need of extracting developer from a developing device at the time of adjusting peeling and transfer output by electrifying the image carrier to have a polarity by which the image carrier is optically discharged at the time of adjusting by an adjusting means. SOLUTION: In the case of adjusting the peeling output of a peeling charger 6, AC voltage and DC voltage (reverse polarity to transfer output) are superimposed and impressed on the charger 6 from power sources for peeling 22 and 23. Thus, a current flows into a photoreceptor drum 1 and a current value is measured by a voltmeter 20. The output of the electrodes 22 and 23 is controlled to a specified value by the adjusting means 31 based on the measured value by the voltmeter 20. In order to prevent the reverse charge of the drum 1, the DC voltage having the polarity by which the drum 1 is optically discharged is impressed on an electrifying charger 2 from a power source for electrification by the control means. Thus, the surface potential of the drum 1 is lowered and the adhesion of the carrier is prevented.

Title: High voltage sweep power source circuit
Inventor: FUJII KOUICHI
IPC: G05F1/613
Filed: 1983-04-18
Abstract: PURPOSE:To improve dynamic characteristics by driving plural power transistors (TR) by field effect transistors (FET). CONSTITUTION:A high-voltage sweep power source circuit is formed by connecting sources of small-signal FETs TR6-TR9 to bases of TR2-TR5 among TR1-TR6 connected in series, and further connecting auxiliary power source circuits C1-C4, D1-D4, and T1-T4 for supplying fine electric power to their drains respectively. When the TR1-TR5 are off, a flowout current to an output by balance resistances R11-R15 is small and auxiliary power source capacity for compensating 0V is reduced. Further, drain power source currents of said TR6-TR9 are required only to compensate maximum values of base currents of the TR2-TR5, so only extremely small capacity is required.
