Title: Manufacture of lateral bipolar transistor
Inventor: YAMAHATA SHIYOUJI
IPC: H01L29/20
Filed: 1986-05-22
Abstract: PURPOSE:To decrease the capacitance of a collector, by performing slant ion implantation in emitter and collector regions with a base electrode as a mask, in order to decrease the carrier concentration in a collector region so that it is lower than the carrier concentration in an emitter region. CONSTITUTION:A dielectric film 9, which is deposited on a GaAs substrate 8, is removed. Thereafter, slant Si ion implantaion of n-type impurities is performed with the metal of a base electrode 11 as a mask. Thus a semiconductor layer comprising an n-type emitter and an n-type collector is formed in the GaAs substrate 8. Slant Si ion implantaion (n2) 22 is performed on the opposite side with the base electrode 11 in-between. When the carrier concentration in the n-type semiconductor region, which is formed in this process, is n2, the carrier concentration of a region 15 is n2 and the carrier concentration in a region 16 is n1. The carrier concentration in a region 17 and a region 18 becomes n1+n2. When the slant ion implantations are performed by different dosing amounts so as to satisfy the relation of n1<n2, the regions 15 and 17 become the emitter region and the regions 16 and 18 become the collector region.

Title: Thyristor converting circuit
Inventor: KUROSAWA TOSHIAKI
IPC: G05F1/585
Filed: 1979-09-12
Abstract: PURPOSE: To block the power source short current caused by the trouble of the control circuit, by adding the 2nd switch circuit of the adverse-operation type in series to the switch circuit.  
     CONSTITUTION: The 2nd switch circuits 22 and 23 are inserted between the phase shifter 10 and the switch circuits 17 and 18 each. The 2nd circuits 22 and 23 perform the opposite operation to that of the circuits 17 and 18 each. In case the circuit 18 is closed by some falut, the circuit 17 is reversed to an open state to block the ignition pulse. On the other hand, the output of the phase shifter 11 never applies the ignition pulse to the thyristor of the bridge 3 since the circuit 23 is opened. As a result, no short is caused to the current of the AC side.

Title: Stripe-shape light emission semiconductor device
Inventor: KAWADA HARUO
IPC: H01S5/00
Filed: 1978-09-21
Abstract: PURPOSE: To enable a atrip-shape current passage to inhibit unnecessary current concentration and heat generation in the neighborhood of an electrode and to achieve efficient current concentration into a luminous region efficiently by making section of the current passage take a form of an inverse trapezoid.  
     CONSTITUTION: Resistance in a stripe is divided into a resistince RC in a joint between an electrode layer 7 and a P-GaAs layer 5 and a stripe layer inside sheet resistance RS. As section of a stripe-shape current passage 10 is made to take a form of an inverse trapezoid, current density on an electrode-forming side becomes lower than a current passage of the conventional shape, a contact resistance RC in a joint surface becomes substantially lower and a layer's inside sheet resistance RS still takes main effect by the area, and therefore, a low sheet resistance becomes obtainable. When these 2 resistances RC and RS became smaller, heat loss by resistance becomes reduced and deteriorating factors caused by action of element becomes inhibited, and therefore, laser rediation efficiency becomes increased.

Title: Mechanical mouse
Inventor: SAITOU ERIKO
IPC: G06F3/038
Filed: 1991-05-22
Abstract: PURPOSE:To easily count pulses by decelerating moving speed in respect to the fine amount of movement and to control the count of pulses by accelerating the moving speed in respect to the large amount of movement by detecting the moving speed of the mouse and generating the pulses according to the detected moving speed. CONSTITUTION:A speed detector 2 and a speed pulse generator 3 are added to the head of a slit pulse generator. The speed detector 2 measures the interval of pulses outputted from a photodetecting diode 1 of a photocoupler and detects the moving speed of a ball. The interval of pulses outputted from the photodetecting diode is in inverse proportion to the moving speed of the ball. The value of the moving speed detected by the speed detector is inputted to the speed pulse generator 3 and the prescribed pulse is generated. At such a time, when the inputted moving speed is high, the speed pulse generator 3 generates a lot of pulses and on the other hand, when the detected moving speed is low, the speed pulse generator is functioned so as to reduce the number of generated pulses. Therefore, the interval of pulses can be controlled corresponding to the speed.

Title: Vacuum pump
Inventor: NOMURA YOSHIHISA
IPC: F04B37/14
Filed: 1983-06-28
Abstract: PURPOSE:To make compact the locking mechanism of an operating piston by constructing a vacuum chamber so as to allow it to be communicated with the atmosphere when negative pressure reaches a prescribed value and reducing residual negative pressure for pulling up the operating piston at its locking. CONSTITUTION:When negative pressure produced by a vacuum pump reaches prescribed pressure, the upper chamber R5 of a cylinder 11h becomes prescribed negative pressure, and a driving piston 62 and a spool valve 61 are moved upward, and thereby allowing an oil through hole 11g to be communicated while a vent 11f to be interrupted. Consequently, engine oil is introduced into the upper chamber R3 of a cylinder 11e, allowing an operating piston 20 to be locked. By contrast, the oil flows into the bore 21e of a piston 21 through the oil through hole 22d of an operating rod 22, allowing a spool valve 69 to be moved. Therefore, the vent hole 21d of the piston 21 is communicated, thereby allowing the vacuum chamber R1 to be communicated with the atmosphere. With this situation, there is no residual negative pressure operating for pulling up the piston 20 to the vacuum chamber R1 at locking the operating piston 20, so that it is possible to miniaturize and make compact the locking mechanism of the operating piston 20.
