Filed: 1992-10-24
Abstract: PURPOSE:To stably and surely emit a transmission light beam to a transmitting destination by accumulating control data when an emitting direction is set at a reference position or the detected result of the emitting direction in a memory circuit. CONSTITUTION:The fitting positions of line sensors 92 and 100 are adjusted so that the movable center of a transmission optical system 14 and the detecting centers of the sensors 92 and 100 are aligned. Then, even when the direction of the optical system 14 is changed large, it is surely detected so that the system 14 is not deviated from a detection range. By regarding the detected results of the sensors 92 and 100 as a reference, an actuator 32 is driven and installing work is simplified. That means, the direction of an emitting direction varying mechanism 16 is decided by setting the varying mechanism 16 to the movable center at a delivery time from a factory, accumulating the detected results of the sensors 92 and 100 in the memory circuit as a reference measured result, operating an operator when a transmission light beam L1 is started to be coarsely adjusted and making the detected results of the sensors 92 and 100 coincide with the accumulated result of the memory circuit.

IPC: H01L21/339
Filed: 1991-11-26
Abstract: PURPOSE:To improve detection sensitivity and reduce noises by providing the configuration where field ion implantation is performed after a field oxidized film is farmed so as to take the detection capacity of a floating dispersion layer less. CONSTITUTION:The surface of a P well 11 formed on an N-type Si substrate 10 is oxidized to form an SiO2 film 12. Then, an SiN film 13 is deposited for patterning. A field SiO2 film 14 is formed by LOCOS and then field ion implantation is performed so that P<+> implantation is made from above the field SiO2 film or through the SiO2 film up to under the SiO2 film for forming a field ion injection P<+> layer 15. The deep P<+> layer is formed on the section to be a floating N<+> dispersion layer where no field SiO2 film exists. By N<+> ion implantation, etc., a floating N<+> dispersion layer 16 is formed. After oxidizatian and opening of a contact, a metal wiring 17 is formed. Since the P<+> layer under the field SiO2 is brought not to contact with the floating N<+> dispersion layer, joint capacity became less and breakdown strength increases.

Filed: 1989-12-01
Abstract: PURPOSE:To surely process information in an optical information processor in which the pulse width of a laser light beam gets >=1mus by applying a bias current which is specified times as large as a laser oscillation threshold to a semiconductor laser. CONSTITUTION:Based on relationship between a light output and the current applied to the semiconductor laser 1, a driving current Id is previously set in a semiconductor laser control circuit 11 so that the bias current Ib may gets 0.75 times to once as large as the laser oscillation threshold Ith. The circuit 11 turns on the laser 1 at the time of non-printing and controls a current value added to the laser 1 so that the light output of the laser 1 may be made constant. Besides, a current value at the time of non-printing, that is, a current at on-time is applied to the laser 1 at the on-time in printing. At the off-time in the printing, the current value obtained by subtracting the current Id from the current at the on-time, that is, the current Ib is applied to the laser 1. In this laser printer, the lowering rate of the light output from the laser 1 is made <=20% even when the pulse width of the laser light beam is infinity.
