Title: Semiconductor device and manufacture thereof
Inventor: KANEKO KENJI
IPC: H01L29/73
Filed: 1983-02-16
Abstract: PURPOSE:To form an emitter region and a thick oxide film region for isolating elements through a self-alignment method by one mask in order to remove a restriction on a distance between both a base electrode and an emitter electrode while preventing a short circuit between a collector and an emitter by using a metal as the base electrode and polycrystalline silicon as the emitter electrode in order to reduce base resistance. CONSTITUTION:An impurity is diffused to a P type base region 811 from a polycrystalline silicon layer 813 to form an emitter region 815. Both ends of the emitter region 815 are determined by thin oxide films 802 protruding from both ends of thick oxide films 808. Consequenly, a transistor of non-walled-emitter structure keeping a predetermined distance by interposing P type base regions 812 of shallow junctions between the emitter region 815 and the thick oxide films 808 for isolating elements can be obtained. The whole surface is oxidized to form oxide films 816 while an emitter is diffused, the oxide films 816 are removd partially while using photo-resist films 817 as masks, and base terminal extracting holes 818 are bored. Lastly, a metal 819 for a base terminal electrode is applied to form a pattern, and a bipolar transistor of structure in the figure (s) is acquired.

IPC: B60T17/22
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To properly judge the abnormality of a valve used when a hydraulic system fails by comprising a pair of hydraulic control valves for controlling the hydraulic pressure, intensifying the pressure of one of hydraulic control valves for a specific time every stop of a vehicle, and detecting the abnormality of the hydraulic system on the basis of the change of the hydraulic before and after the braking operation.

That is, the hydraulic pressure of a wheel cylinder W/C of a diagonal wheel is detected by the pressure sensors P1, P2 in a case when the pressure intensifying, the pressure reduction and the retaining control are not executed by the automatic brake control, and the pressure at that time is stored in a predetermined memory. Then SoL1, SoL5 for pressure intensifying are operated to intensify the pressure in the main oil pressure system, the pressure after pressure intensifying is stored in another specific memory, the deviation of pressure before and after the pressure intensifying is determined, and a predetermined value (value stored in advance in memory) obtained by the pressure intensifying in a normal state, is compared with the pressure deviation, whereby the abnormality judgement is executed to judge the abnormality in a pressure intensifying system.

IPC: H05K3/32
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To determine GO/NO-GO of electrical joint between an electronic device and a board eastly in units of joint. SOLUTION: GO/NO-GO of electrical joint between a bump 1b and a board electrode 2a can be determined based on the variation in the quantity of reflected light of an irradiated laser light LB. Presence and fusion of the bump 1b can also be determined. When criteria for deciding GO/NO-GO of joint, e.g. the quantity of reflected light, are determined previously, GO/NO-GO of joint can be determined easily in units of joint based on the variation in the quantity of reflected light to be detected. In other words, a detective circuit module can be corrected simply by repairing only the defective part as compared with a conventional method requiring reconnection of the entire device and the device can be protected against application of undue thermal stress.

Abstract: PROBLEM TO BE SOLVED: To control lift of a hydrofoil to a certain value by changing an elevation angle of the hydrofoil by expanding and shrinking an actuator to increase and decrease lift and balancing energizing force F due to lift and generation force P of the actuator when F differs from P. SOLUTION: A mounting mechanism of a hydrofoil 1 is constituted in such a manner that proportional constant of lift L and energizing force F due to lift is changed substantially linearly for an elevation angle α of the hydrofoil 1. A spring energizing device X which generates generation force P by the spring energizing device is constituted in such a manner that the generation force P is balanced for the energizing force F due to lift and is balanced. When lift L is generated from the elevation angle α and lift L is increased beyond necessity, the energizing device X is pressed through a control cylinder pressing link 3. Force of the energizing force F due to lift is increased, an energizing spring 7 is shrunk by a stroke S, the elevation angle α is reduced, and lift L is also reduced. Moreover, the generation force P is increased to balance them.  Consequently, a lift controller is controlled to bring lift L to a certain set value.
