Title: Semiconductor device
Inventor: SATOU NORIFUMI
IPC: H01L21/8244
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To facilitate low voltage operation by adjusting an amount of impurity in an adjustable impurity layer and thereby independently adjusting threshold voltages when either a source or a drain of an input/output transistor becomes the ground potential and when both of the source and the drain come near the VCC power supply potential. SOLUTION: A local structure and a concentration of a tub 1a near channel regions 3a, 3b of a first and a second input/output MOS transistor are different form those of a tab 1a near a first and a second memory MOS transistor and impurity concentration of the channel regions 3a, 3b and of an adjustable impurity layer 4a are individually set. About the first and the second input/output MOS transistor, threshold voltage values when either a source or a drain becomes the potential of a first power supply and when both of the source and the drain come near the potential of a second power supply are independently set. By this method, a device can be operated with low voltage easily.

IPC: G11C17/00
Filed: 1983-04-08
Abstract: PURPOSE:To attain high speed operation and to prevent malfunction by providing an MOSFET for precharge between each data line and a power supply terminal. CONSTITUTION:When a precharge pulse thetap is brought into a low level, P type FETsQ4, Q5-Q7 for precharge between a common data line CD, data lines D0, D1- and a terminal of a power supply voltage VDD are turned on so as to precharge the lines CD and D0,D1-. The precharge is attained in a short time by independent precharge of the lines CD and D0, D1- and a precharge voltage goes to a high level not affected by a threshold voltage of the FET of a column switch. As a result, the operation of a transversal ratio ROM is quickened and generation of malfunction is prevented.

Abstract: PURPOSE:To remove dust that develops in a discharge space due to a main discharge between a cathode and anode and stabilize laser output by providing a dust removing means to the passage of a circulating gas laser medium. CONSTITUTION:A dust removing means 21 is provided between an air blower 9 and a heat exchanger 11 that is the passage of a gas laser medium in a laser tube 1 in such a way that its means is prepared to a length of about an overall length of the above laser tube in the direction that intersects perpendicularly to the flowing direction of the gas laser medium. The dust removing means 21 is composed of: a plate like filter part 22; a capture part 23 that is mounted at the side face of the filter part 22. Consequently, once the gas laser medium flows into the capture part 23 along a pair of inclined walls 25, only dust mixed in the medium is captured by the filter part 22 and only the normal gas laser medium that is free from dust may pass through. Instability and lowering of laser light output due to a state of dust development which is caused by a main discharge is thus prevented.

Abstract: PURPOSE:To easily and surely detect the presence or absence of a defect in the screw threads in the joint part of a pipe by detecting the presence or absence of a reflection echo while spirally moving an ultrasonic probe by directing the emission beam thereof toward the base direction of the screw threads. CONSTITUTION:The ultrasonic probe 3 is mounted to one end of a moving body 4 screwed to the screw threads 10 so as to come into contact with the surface of the outside cylinder of an internal thread part 1a.

Abstract: PURPOSE:To shorten an arithmetic time by rotating a point on an orthogonal coordinates until its X and Y components attain to alpha, and finding sin<-1>alpha and cos<-1>alpha from the angle of rotation. CONSTITUTION:A vector (1,0) on an (x) axis is rotated by tan<-1>1/1(=45 deg.). The angle of rotation is decreased successively in the order of tan<-1>1/2, tan<-1>1/4, tan<-1>1/8...tan<-1>1/2n. Further, when the (y) component after the rotation is greater than alpha, clockwise rotation is performed next and when the (y) component is smaller than alpha to the contrary, counterclockwise rotation is performed. The angle of rotation approximating alpha is an angle to be found. The X and Y components after the rotation are stored in an X register 5 and a Y register 6. The contents of both registers 5 and 6 are inputted to a 1/2<n> arithmetic device, where they are processed to find the X and Y components after the rotation. This operation is repeated.
