Patent JP-S6112071-A (JP)
Title: Semiconductor device
Inventor: INADA MASAAKI
IPC: H01L29/08
Filed: 1984-06-27
Abstract: PURPOSE:To prevent such a trouble as a drop in hFE from generating even though the junction of the emitter and the base is made an avalanche breakdown by a method wherein the low-impurity concentration emitter region is formed in such a way as to encircle the periphery of the high-impurity concentration emitter region as the emitter region of the bipolar transistor. CONSTITUTION:Firstly, such an impurity as arsenic is diffused in a low-concentration emitter region 2-1 using thermal oxide films 2-3 as masks. Then, such an impurity as arsenic is ion-implanted in the inner side of other low-concentration emitter region 2-1 in the condensed concentration using a photo resist and so forth as masks to form a high-concentration emitter region 2-2. By this way, even though the junction of the emitter and the base part is made an avalanche breakdown, the avalance breakdown in the junction of the emitter and the base part is made to generate more in the central part of the emitter, because the concentration of the implanted impurity in the peripheral part end of the emitter is lower than that in its central part. Therefore, no avalanche breakdown is generated in the corner part ends of the emitter and the center of recombination is not concentrated in the insulating film, which is located at the corner part ends. As a result, the hFE in the low-current region is never lowered even after the avalanche breakdown.

Title: Manufacture of semiconductor device on insulated substrate
Inventor: MAEGUCHI KENJI
IPC: H01L27/12
Filed: 1979-10-16
Abstract: PURPOSE:To prevent disconnection by a method wherein the first opening is provided in an insulated layer adjacent to a semiconductor element region on an insulated substrate, the second opening reaching the substrate is then provided on the surface insulated layer after a primary wiring is extended as far as the bottom of the hole, and a secondary wiring is formed and connected with the primary wiring end in the hole. CONSTITUTION:An MOS transistor region 43 and a gate oxidized film 44 are formed on a sapphire substrate 41 adjacently to a fiel oxidized film 42. An opening is provided in the oxidized film 42, a polycrystalline Si 45 for a gate electrode and a primary wiring is accumulated to patterning, which is extended so as to cover a part of the hole bottom. Next, it is covered with CVD SiO2 46, the primary wiring end and the substrate are exposed through selective opening, and an Al secondary wiring layer 47 is formed. Since the primary wiring layer 45 is arranged in the first opening zone partly in contact with the bottom of the substrate, a bottom will not be formed to provide the second opening, and hence there occurs no disconnection of the secondary wiring layer. Furthermore, there may be no room required between the first and the second holes, and hence integrity can be improved.

Title: Elevator of access ramp
Inventor: SEKIGUCHI GOICHI
IPC: B63B27/14
Filed: 1978-10-27
Abstract: PURPOSE: To attain the horizontal and inclined postures of the access ramp easily and quickly by expanding or contracting two wires, which are coupled with the front and rear ends of access ramp respectively, by means of a winch at the same time.  
     CONSTITUTION: When the access ramp 34 is used as an elevator, the cylinders 26, 27 are full extended to make the access ramp horizontal, and the winch 23 is operated. The access ramp can be vertically moved up and down since the wires 21, 22 are expanded or contracted by the same length. Also, when the wharf side cylinder 26 is contracted from the horizontal state, the wires 21, 28, 29 are pulled upwards through the free pulley 24, the front end of the access ramp ascends. On the other hand, when the deck side cylinder 27 is contracted, the rear end of the access ramp ascends. In this way, an arbitrary angle of inclination of the access ramp can be obtained.

Title: Control method for angular acceleration
Inventor: KUWABARA MASAYUKI
IPC: G05B19/416
Filed: 1987-05-28
Abstract: PURPOSE:To enable a user to automatically set the angular acceleration of an optimum revolving motion just by setting the state of a load, by calculating previously the optimum angular acceleration in a list based on the elements, i.e., the load weight and the load centroid eccentricity value. CONSTITUTION:The inertia moment of a rotary shaft is calculated based on the load weight 19 and the load eccentricity value 20. Then the optimum acceleration/deceleration time (angular acceleration) is calculated for each of load conditions. These calculated inertia moment and angular acceleration are registered into a list containing the weight 19 and the value 20. When a robot works actually, both the weight 19 and the value 20 are designated and the acceleration/deceleration times corresponding these weight and value are obtained from said list. Thus an angular speed is decided. In such a way, the optimum angular speed control is attained for revolving motions.

Title: Geysering prevention method in low-temperature liquid transport pipe
Inventor: MORI MIKIROU
IPC: F17D1/20
Filed: 1982-07-29
Abstract: PURPOSE:To prevent geysering by allowing gas to flow into a transport pipe little by little to stimulate the low-temperature liquid in the transport pipe. CONSTITUTION:The gas generated in a transport pipe 3 enters a tube 10 through a rise section 3a. When the liquid level in the tube 10 is pressed by the gas and lowered to the lower limit, an adjustint valve 13 is opened by a signal from a liquid level controller 11, and the gas in the tube 10 is discharged through a pipe 12. In case a transport pump 2 is stopped and the low-temperature liquid in the transport pipe 3 does not flow, an adjusting valve 8 is opened by a signal from a flow controller 9. Accordingly, part of the gas evaporated in a tank 1 and pressurized by a compressor 5 is continuously fed little by little into the transport pipe 3 from a pipe 6 through an orifice 7. Therefore, the low-temperature liquid in the transport pipe 3 is applied with stimulation by the gas, thus the heating of the low-temperature liquid in the transport pipe 3 is prevented thereby geysering can be prevented.

IPC: G03G13/08
Filed: 1977-11-07
Abstract: PURPOSE: To obtain a good quality copyfree from the ground contamination after the deterioration of photoreceptor characteristic by detecting the surface potential of the potoreceptor after having made an exposure before the start of a copy cycle, and setting the amount of bias which agrees with the level value o its detection.  
     CONSTITUTION: Drum-like photoreceptor 1 is rotated at constant speed, and surface potential motor 2 and bias potential 3 are disposed near its outer circumference. The surface potential of photoreceptor 1 detected by the surface potential meter 2 is applied to switching circuit 10 of memory control circuit 4 which read the surface potnetial and discriminates it. Counter 16 converts the maximum analog amount of the surface potential of the photoreceptor 1 to digital amount so as to retain it for long time. This digital amount is applied to attenuator 18 in the bias voltage control circuit 5. After it is converted to voltage which corresponds to the digital amount it is amplified by amplified 19 to bias voltage which corresponds to the digital amount. This amplified bias voltage is applied to bias electrode 3. Accordingly, a good quality copy can be obtained even after the deterioration of the photoreceptor.

Title: Lighting controller for turn lamp of vehicle
Inventor: IKEDA TOSHIKI
IPC: B60Q1/40
Filed: 1988-05-30
Abstract: PURPOSE:To accurately execute the turning action by blinking a turning lamp during a turning decision period elongated when vehicle speed is low and continuing the blinking as a turning action when the steering angle becomes over the specified angle during the turning decision period. CONSTITUTION:When a turn switch 5 is operated to the left or the right, the turning action decision part 13 of a control means 10 sets a turning decision period which is long when the vehicle speed detected by a sensor 11 is low compared when the speed is high. During the period a turning lamp 8 or 9 blinks. When a steering angle sensor 12 detects that the steering angle greater than the specified angle during said period, the turning indication action of continuing blinking of the turning lamp 8 or 9 is newly executed. As a result, when a vehicle is cornered at a low speed at an intersection, for example, a relatively long turn decision period is set after the turning switch 5 is turned on so, whereby accurately executing the turning action even if a steering wheel is turned at a relatively slow rate.

Title: Driving device for recording medium disk
Inventor: INOUE KAZUHIKO
IPC: G11B17/028
Filed: 1984-06-28
Abstract: PURPOSE:To faciliatate adjustment and repair by putting a clamper in operation while a disk cartridge is no inserted. CONSTITUTION:A carriage control mechanism does not release a carriage 63 from being held by reacting to the operation of the clamper 26, but releases a carriage 63 from being held by reacting to the insertion of the disk cartridge 20, so that a head 55 becomes able to move toward the disk. Therefore, it is not necessary to add a mechanism which prevents a couple of heads 54 and 55 from contacting each other to a moving mechanism 25 for the clamper 26, and the clamper moving mechanism 25 is put in operation although the disk cartridge 20 is not inserted, thereby performing adjustment or repair. Further, the carriage control mechanism does not inhibit the clamper moving mechanism 25 from operating, so it does not receive strong force from the clamper moving mechanism 25. Thus, the carriage control mechanism is constituted relatively simply.

Title: Power amplifier circuit
Inventor: TAKANO HISAO
IPC: H03F3/20
Filed: 1978-11-01
Abstract: PURPOSE:To make it possible to adjust easily a voltage amplification factor and frequency characteristics by miniaturizing the shape of a power transformer by using a differential amplifier for a feedback circuit while adapting an open power supply to the power supply of a current amplifier circuit. CONSTITUTION:Once a positive signal is inputted to terminal 8, the output of differential amplifier 9 becomes positive and transistors Tr10-Tr12 turn ON. As a result, a current flows from the positive terminal to negative terminal of galvanometer 3, the pointer of which moves in its positive direction. Next, when a negative signal is inputted to terminal 8, the output of amplifier 9 becomes negative, causing Tr13 to turn ON. As a result, Trs 14-16 turn ON to flow a current from the negative terminal to positive terminal of galvanometer 3, allowing the pointer to move in its negative direction. When a positive input is applied to terminal 8, a voltage across galvanometer 3 is applied to differential amplifier 17 and then fed back to the inversion input side of amplifier 9. Next, a negative input applied to terminal 8 inverts the voltage across galvanometer 3 and it is fed back to the inversion input side of amplifier 9.

Title: Ground liquefying sensor cable and method for determining liquefaction of ground
Inventor: ONO NAGAYUKI
IPC: G02B6/44
Filed: 1994-05-24
Abstract: PURPOSE:To decide liquefaction of the ground by embedding a sensor cable into the ground and specifying the liquefaction of the ground online in a wide area. CONSTITUTION:The optical fiber sensor consists of two pieces of optical fibers respectively disposed in the outer peripheral direction of cylindrical coil springs along the longitudinal directions of these springs. The sensor cable 11 having such optical fiber sensor is embedded into the ground 12. the ground 12 exhibits the behavior similar to the behavior of liquid and buoyancy acts on the sensor cable 11 when the liquefaction is generated by the earthquake. The sensor cable 11 is bent largely upward by the buoyancy near the boundary between the liquefied area 14 and the non-liquefied area 15. As a result, the optical fibers on the compression side where the pitches of the coil springs are narrowed are distorted and the light quantity when the light pulses entering from one end of the optical fibers returns to the incident end is attenuated by the local bending thereof. On the other hand, the light quantity of the optical fibers disposed on the tension side does not change and, therefore, the light quantity of the optical fibers on the compression side and the tension side is discriminated. The bending direction of the sensor cable 11 is estimated and the decision of the liquefaction is executed.
