Title: Semiconductor light detector
Inventor: TSUJI TAKAFUMI
IPC: H01L31/105
Filed: 1981-09-17
Abstract: PURPOSE:To obtain a semiconductor light detector by which withstanding voltage around an element can be increased and reliability is improved, without decreasing high speed response and photoelectric transducing efficiency. CONSTITUTION:In a P-I-N photodiode, a P-Cd high concentration diffused layer (a third semiconductor crystal layer) 16 wherein Cd is diffused is formed on a light incident surface of an upper part of a low impurity concentration N-InP epitaxially grown layer 14. In this case, the light incident layer of the N-InP epitaxially grown layer 14 is formed in a concave shape, its central part is flat, and its outer peripheral part is formed in a curved surface which is smoothly continued to the central flat part. In this constitution, degradation of the withstanding voltage at the peripheral part of the junction part between a second semiconductor crystal layer 15 and the third semiconductor crystal layer 16 can be prevented just like the effect of a guard ring. The concentration of an electric field at the peripheral part can be prevented just like the case of Rogowski electrode. Uniform avalanche multiplication is generated at the central part where light is imputted and an S/N ratio can be increased.

Filed: 1991-05-23
Abstract: PURPOSE:To eliminate an assembling error and to improve the assembling accuracy and workability by using a common guide rail to guide each holder in the seeking direction for the drivers of an objective lens and a magnetic heed. CONSTITUTION:A mobile part (carrier) 1 of an optical head holds an objective lens holder 3 to be moved along the guide rails 2 and 2 extending in the seeking direction with an elastic substance 4. The holder 3 holds an objective lens 6. A magnetic head 12 opposite to the lens 6 is held by a head holder 14, and the holder 14 moves along the rails 2 and 2. Then the lens 6 moves in the direction vertical to the surface of a magneto-optical disk with the electromagnetic force generated in response to the values of currents flowing to the coils 11 and 11. Thus the focus control is carried out. The carrier 1 moves in the seeking direction with the electromagnetic force generated by the currents flowing to the coils 10 and 10. So that the movement is controlled over an entire area in the tracking direction. Meanwhile the heed 12 is independently controlled with the electromagnetic force generated by the current flowing to a coil 18.

Title: Exposure method in laser printer
Inventor: INOUE MOTOICHIRO
IPC: B41J2/44
Filed: 1984-07-16
Abstract: PURPOSE:To decrease effectively the fluctuation of an effective spot diameter of laser light applying exposure scanning to a recording medium by storing in advance a deviation between a main scanning line and a spot locus and controlling the modulation intensity of the laser light according to the deviation. CONSTITUTION:A decoder 30 generates a normal signal when a deviation known in correspondence to the count value of a counter 28 does not exceed + or -DELTA and generates a signal weakening the modulation when the deviation exceeds it. Then a differentiation device 32 applies a normal signal fed from the decoder 30 and a weakening signal to a modulator power supply 34 as a signal combined smoothly. Thus, a modulation signal fed to an AO element 12 changes smoothly between the normal level and the weak level and the modulation intensity is fluctuated. When the modulation signal is at a normal level, the intensity distribution of the laser luminous flux is as shown in a curve 3-1 and when at a weak level, the distribution is expressed in a curve 3-2 by the adjustment. Thus, the fluctuation of the effective spot diameter of the laser light applying exposure scanning to the recording medium is reduced independently of the deviation between the main scanning line and spot locus.

Title: Ac electrolytic cleaning method and equipment
Inventor: NAITOU HIROMITSU
IPC: C25F1/00
Filed: 1977-12-09
Abstract: PURPOSE: To simplify a cleaning equipment by carrying out AC electrolysis to control formation of gas when stains on the surfaces of a cold rolled steel sheet are removed in an alkali detergent soln.  
     CONSTITUTION: Electrodes 9... are alternately arranged in the electrolytic cleaning tank in the running deirection of steel strip 8, and AC voltage is applied to electrodes 9... . Thus, rolling oil and other stains on the strip surfaces are removed in an alkali detergent slon. The results such as the amt. of fats and oils, and iron powder left on the strip surfaces after the electrolytic cleaning are comparable to an electrolytic cleaning method applying DC voltage. Accordingly, an expensive DC power tource unit becomes unnecessary, formation of gas due to electrolysis is controlled, and a danger of explosion can be eliminated, so the cleaning equipment is made of open type and simplified.

IPC: H02B13/02
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To accurately detect wear of a contact, and enable accurate detection or presumption of time for a component exchange by providing an operating member which touches a lever for rotating the lever, moving the movable electrode of a vacuum valve from its off-position to its on-position, and surely detecting a change of the distance of that movement. SOLUTION: The fixed electrode 11a of a vacuum valve 11 is approached to its movable electrode 11b by rotation of a lever 20, and, after the vacuum valve 11 is caused to be in a closed state by an operating mechanism, the movable electrode 11b touches the fixed electrode 11a. Whether or not the movable electrode 11b touches is detected by a detector, and the distance of movement of the movable electrode 11b is measured. Consequently, states of wear and tear can accurately be detected when maintenance and inspection are performed, though the fixed electrode 11a and the movable electrode 11b wear and tear because of mutual collision, melting, abrasion, etc., as the vacuum valve 11 is repeatedly used.

Abstract: PURPOSE:To make an inverting distance small, prevent unusual tensile force from acting, and prevent movement in the width direction at the time of change in tensile force by putting a belt around a first pulley having an axis nearly 45 deg. inclined to the running direction of the belt, a second pulley having an axis parallel to the running direction, and a third pulley having an axis nearly 90 deg. inclined to the first pulley, in this order. CONSTITUTION:All of first, second, and third pulleys 20, 24, 27 have a cylindrical shape and the first pulley 20 has an axis nearly 45 deg. inclined to the running direction of a belt 16, the second pulley 24 has an axis parallel to the running direction, and the third pulley 27 has an axis nearly 90 deg. inclined to the first pulley 20, and the belt 16 is put around them in the order of the first, second, and third pulleys 20, 24, 27. As a result, the distance required for inverting the belt 16 can be made small without causing unusual tensile force to act on the edge parts of the belt 16, thereby, increasing its life. Further, it is prevented that the belt 16 is displaced in the width direction due to change in tensile force, enabling even a belt having a large width and a large weight to be smoothly inverted.

Title: Production of optical packing material
Inventor: TANAKA HIDEO
IPC: G02B1/04
Filed: 1991-06-19
Abstract: PURPOSE:To improve the workability of sticking and to obviate the leakage after sticking by filling an optical packing liquid between optical parts, then forming fine particles in the optical packing liquid. CONSTITUTION:After the optical packing liquid is filled between the optical parts 1 and 2, the fine particles are formed in the optical packing liquid in the case of production of the optical packing material 3 consisting of the optical packing liquid and the fine particles dispersed in the optical packing liquid. For example, metal alkoxide is dissolved before or after the optical parts are stuck to each other and thereafter the optical packing liquid is hydrolyzed by the dissolved water content in the liquid or the catalyst previously dissolved therein to allow the fine particles of the oxide to form. The holding of the optical packing material 3 is, therefore, attained. Then, the workability at the time of sticking the optical parts 1, 2 to each other is improved and the leakage of the optical packing material 3 is obviated even after the sticking. For example, alkoxysilane, alkoxytitanate, etc., are used as the metal alkoxide.
