Title: Vapor growth method
Inventor: ISHIKAWA HIDETO
IPC: H01L21/205
Filed: 1987-08-28
Abstract: PURPOSE:To reduce or annihilate N-type conduction on the interface of an epitaxial growth layer and an InP substrate by thermally treating the InP sub strate for thirty min or more at a growth temperature or more in a PH3 atmo sphere before growth, changing over PH3 to a reaction gas and starting vapor growth. CONSTITUTION:An InP substrate 1 is arranged onto a susceptor in a reaction tube, and the inside of the reaction tube is supplied with PH3 in a 20% hydrogen base and H2 gas as a carrier gas at normal pressure before growth. The InP substrate 1 is heated, the temperature of the substrate is kept at a vapor growth temperature of 640 deg.C, and the state is maintained for a fixed time and the supply of PH3 is stopped. The gas is changed over and the inside of the reaction tube is fed with a reaction gas composed of AsH3, trimethylpotassium and trimethylindium together with the carrier gas, and the growth of undoped GaInAs 4 is started. The holding time when the InP substrate is held in a PH3 atmosphere is increased while sheet carrier concentration No representing conduc tion on the interface 5 is reduced. When the holding time is lengthened to thirty min or more, sheet carrier concentration No can be diminished extremely or brought to zero.

Title: Laser beam irradiation apparatus of laser treatment device
Inventor: FUKAO HAJIME
IPC: A61N5/06
Filed: 1987-08-28
Abstract: PURPOSE:To perform effective laser treatment by enlarging an irradiation range by one laser irradiation head, by successively scanning the surface area on the affected part in an X-Y axis direction by the irradiation spot of laser beam reflected from the laser beam reflecting mirror arranged on the way of the beam path between the laser irradiation head and the affected part of a patient. CONSTITUTION:The excitation of the coil 6b on an X-axis side and that of the coil 6d on a Y-axis side are made synchronous and a mirror 5 is moved in the two-dimensional direction of an X-Y axis along with an iron core 6a while shaken around the pivot point of a shaking shaft 7. The irradiation spot P of the laser beam emitted from a laser irradiation head 1 and reflected by the mirror 5 on the way to irradiate the affected part 4a successively scans a square surface region in the X-Y axis direction so as to again return a start point 1 on a moving locus at every cycle T from the start point 1 through points 2, 3, 4,...,5. By this method, the scanning of the surface region of a predetermined range by the laser beam spot in an up-and-down as ell as left-and-right directions (X-Y axis direction) is repeatedly performed. Therefore, even when the affected part 4a extends over a cartain range, correspondence can be taken by one laser irradiation head.

Title: Small fuel cell power supply
Inventor: NISHIZAWA NOBUYOSHI
IPC: H01M8/04
Filed: 1992-08-12
Abstract: PURPOSE:To safely control the pressure of a hydrogen storage alloy charged cylinder for generating hydrogen as fuel by providing a control means to regulate exhaust gas from a fuel cell body according to the extent of a load. CONSTITUTION:When a load detected with an ammeter 15 is large, a motor 12 is driven on the basis of a shutter closing instruction from a control device 11, and a shutter 14 is thereby closed. Consequently, exhaust gas from a fuel cell body 3 is directly discharged outside and a rise in the temperature and pressure of an MH cylinder 4 gradually slows down. Thereafter, when a load drops to a normal value, the motor 12 is driven on the basis of a shutter opening instruction from the control device 11, thereby opening the shutter 14. As a result, exhaust gas flows around the MH cylinder 4, and the temperature and pressure thereof rise. Then, a hydrogen storage alloy in the cylinder 4 releases hydrogen and this hydrogen is supplied to the anode 2 of the fuel cell body 3 via a hydrogen feed tube 5. Thus, normal power generation can take place.

Title: Testing circuit for semiconductor integrated circuit
Inventor: TAKAHASHI HIDEO
IPC: H01L21/822
Filed: 1989-08-22
Abstract: PURPOSE:To dispense with a terminal for setting readiness of a test by making a test ready in an LSI having a testing circuit built therein only when a data of specified N bits is inputted continuously into a shift register at a specified address. CONSTITUTION:An LSI 1 consists of an internal circuit and a testing circuit having a 3-bit shift register 21, a decoder 22, an AND 20 and the like. When -Adr2 is selected as address and 1, 0 and 1 are written into an LSB15 of a data bus by a writing signal in the order, 1, 0 and 1 as outputs Q1, Q2 and Q3 respectively of the register 21 are decoded with the decoder 22 and a test enable output 23 thereof shifts to 1. With the shifting of the output 23 to 1, any enable output will not be released unless a reset signal is turned to 0 even if another address is selected. Then, when an address -Adr1 is selected and 1 is written into a DFF 24 by a writing signal, an output of the AND 20 shifts to 1 to enter a test mode. This eliminates the needs for an enable terminal.

Title: Line tracking system
Inventor: JINBO YUUJI
IPC: G06T9/20
Filed: 1983-11-16
Abstract: PURPOSE:To attain high speed of line tracking processing by comparing the black width in horizontal direction with the black width in vertical direction and tracking a line based on the narrower width. CONSTITUTION:The length of black run in X direction and that of a black run in Y direction are compared and a tangential vector is formed on the basis of the narrow width. Then the shorter address is used as a tracking address. On the other hand, the tracking address is changed to measure the width of a picture data thereby applying decision whether the width is proper or not. That is, when the width is wider, it means that it is a branch point and when the width is narrower, it means that it is an end point. When the value is proper, the deviation between the center data value and the tangential vector calculated before is extracted and when the deviation is large, the point is processed as a curved point and when not, the tracking is continued further.

IPC: G11B5/39
Filed: 1981-12-28
Abstract: PURPOSE:To reduce noises while a recording medium runs over a slide and to eliminate the breaking of a signal lead-out conductor by preventing the signal lead-out conductor from being exposed in a recording medium facing surface. CONSTITUTION:Signal lead-out conductors 7 and 8 of a magnetoresistance head are covered with an electric insulating layer 5 while put slightly behind a medium sliding surface 10 and the conductors 7 and 8 are not exposed in the medium sliding surface 10. Further, the 2nd electric insulating layer 5' which is not exposed in the medium sliding surface 10 covers the upper parts of the signal lead-out conductors 7 and 8. The electric insulating layer 5' may use the  same material with the electric insulating layer 5. The signal lead-out conductors  7 and 8 are arranged in contact with a magnetoresistance element 6. The  magnetoresistance head of said constitution does not has the conductors 7 and 8  exposed in the medium facing surface 10, so neither of signal led-out conductors  7 and 8 extends differently from a conventional magnetoresistance head 1.  Therefore, the generation of noises due to said extension is prevented. Further,  there is no possibility of a short circuit, so electric insulating layers 4 and 5 are thinned.
