Title: Semiconductor integrated circuit device and its testing method
Inventor: MASUDA MASASHI
IPC: H01L27/04
Filed: 1988-11-21
Abstract: PURPOSE:To automate the test of a subject to be tested by reading chip information from the inner part of a chip to an outer part and using a test pattern automatically edited based on the chip information. CONSTITUTION:When a control means 14 inputs an external control signal S1, the identification codes of respective function modules 12 which are previously registered in the memory table of an information output means 13 in a design step can be read outside a semiconductor integrated circuit device 11 as an identification information signal S2. Consequently, individual function information of the function modules 12 in the chip can promptly be obtained without artificially retrieval-processing design data in the design step. Thus, the test of the subject to be tested 11 can be automated by using the test pattern which is automatically edited based on the chip information.

Title: Wiring method using joint box secured by binding wire bundle
Inventor: KAWAGUCHI TAKEO
IPC: H02G3/00
Filed: 1993-10-19
Abstract: PURPOSE:To allow setting of a binding wire bundle at an arbitrary position in an arbitrary direction by selecting the length and the shape of a coated wire between a structural member and a binding wire bundle arbitrarily and separating the preceding binding wire bundle from the structural member without fixing at a predetermined position. CONSTITUTION:Coated wires 8 are wired reversely on a structural member 7 while increasing the length up to a binding wire bundle A and a box 1 is applied to the binding wire A bundle A at the forward end thereof. The coated wire 8 is then shaped substantially into U-shape between the structural member 7 and the binding wire bundle A before it is wired. The box 1 is applied normally to the binding wire bundle A directing upward. In other words, the length and shape of the coated wire 8 are selected arbitrarily between the structural member 7 and the bundle A thus setting the bundle A at an arbitrary position in an arbitrary direction. Since the box 1 is applied instantaneously to the bundle A and installed separately from the structural member 7, the work is simplified significantly and facilitated.

Filed: 1986-12-11
Abstract: PURPOSE:To eliminate the formation of a precipitation nucleus by a method wherein a chemical vapor growth substance which is deposited in advance on a substrate other than a semiconductor substrate by a chemical vapor deposition (CVD) method is attached to the surface of the semiconductor substrate so that the semiconductor substrate can be stuck.

Title: Formation of water-repellent surface
Inventor: OKUBO AKIO
IPC: C09K3/00
Filed: 1997-10-13
Abstract: PROBLEM TO BE SOLVED: To facilitate a strong water repellency to be imparted to a solid surface and facilitate the degree of water repellency to be controlled by spraying fire particles coated with a water repellent to the surface to thereby attach the water repellent to the surface and simultaneously to impart fine uneven structure thereto. SOLUTION: Any fine particles can be used as far as they does not impair the function of a water repellent. Inert substances (e.g. ceramics) are pref., though metal oxides and metals may be used. Alumina is a typical ceramic. A silicone oil (e.g. dimethylpolysiloxane) is an example of the water repellent. Coated alumina particles are prepd. by mixing alumina with a suitable amt. of a dimethylpolysiloxane soln. and drying the resultant mixture. For spraying fine particles, an air blast apparatus is used. When the coated particles collide with a solid surface, the water repellent on the particles are transferred to the surface and simultaneously an uneven structure is formed.

Title: Converter device
Inventor: KUBOTA HIROSHI
IPC: H05B41/24
Filed: 1990-11-01
Abstract: PURPOSE:To obtain a converter device for protecting a transistor even when an extraneous surge is applied by connecting diodes in parallel to a current transformer of a feedback circuit, and by using the diode of slow diode characteristic as this diode. CONSTITUTION:Diodes D2-D4 are connected in parallel to a secondary coil Tr2 of a drive transformer Tr (current transformer). The diodes D2-D4 are of slower diode characteristic compared with that of a conventional diode. Namely, the tilting of a static characteristic curve is smaller in a low injection region, and an electric potential obstacle is thus small. Even when an extraneous surge is applied, due to the diodes D2-D4 of slower diode characteristic, an erronous operation due to extraneous surge can be prevented for a switching device. The breakeover and the destruction of a transistor Q (switching device) at the time of application of extraneous surge can thus be prevented.

Abstract: PURPOSE:To reduce an energy-loss by connecting a part between a flow-rate control valve and a pressure generating means of a discharging pipe passage to a supply pipe passage between a pressure oil supply source and the flow-rate control valve via a check valve, thereby constituting a regenerative circuit. CONSTITUTION:In speed control over a free-fall phenomenon by means of a meter-out system, a diaphragm 30, which is placed between a flow-rate control valve 13 and a reservoir 16 and which acts as a pressure generating means, functions as a base of a variable diaphragm, in a meter-out system, and a part of the return oil from a hydraulic actuator 4 flows onto a supply side at the downstream side of the flow-rate control valve 13 via both a regenerative circuit 31 and a check, valve 32.

IPC: H02P25/026
Filed: 1991-10-18
Abstract: PURPOSE:To realize torque control or speed control through a single signal line without sacrifice of the characteristics of synchronous motor by employing a detector having an output obtained by converting a plurality of field pole position detection signals or speed detection signals into a single signal. CONSTITUTION:When signals U, V, W from a pole position detector 2 and a speed detector 3 are passed through an adder, they are combined according to the difference of input resistance (R, 1.5R, 2R) and a single signal is outputted from the adder. When thus derived signal is passed through a multiplier, an output signal VOUT and a speed detection signal phiA are multiplied to produce a pulse signal fOUT having different peak value and a single signal having pole position signal component and speed signal component is taken out. Consequently, a plurality of field pole position signals can be converted into signals having different peak values through analog conversion and when thus converted signals are passed through a current phase controller 7 or a speed converter 6 and taken out as current phase signals or speed feedback signals, high performance speed control of synchronous motor can be realized.
