Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To allow the circuit to hardly receive effect of noise or ghost disturbing due to a weak electric field by sampling data at a place where the effect of noise is hardly received. SOLUTION: When a masked start bit detection signal is outputted, a variable frequency divider 71 starts frequency division of a clock signal CK after the lapse of a prescribed time to generate a sampling clock signal SCK. A frequency division ratio is selected so that the period of the signal SCK is the same as a period of a data bit DB and a sampling timing is set to be a time in the middle of a block of data bits DB1 to DB15. A counter 72 is initialized by a horizontal synchronizing signal and when the signals SCK by 15 pulses are counted, the count signal is validated and the variable frequency divider 71 changes the frequency division ratio and a pulse for the DB16 is generated. That is, the sampling timing of the bit DB16 by the sampling clock signal SCK comes this side in the block of the bit DB16.

Title: Light-responsive superconducting laminated film
Inventor: ENOMURA AKIO
IPC: H01L39/22
Filed: 1992-06-23
Abstract: PURPOSE:To obtain a light-responsive superconducting laminated film capable of extremely high-speed optical switching at low power consumption in a condition of normally-on or normally-off, by joining a 3d transition metal oxide to a copper oxide superconductor. CONSTITUTION:After a Bi2Sr2Ca2Cu3O10 thin-film 3 is formed by 2-pole RF sputtering on an MgO single crystal substrate 7 with an exposed (100) face, it is heated in the air at 800 deg.C for 5 hours and in an air current of oxygen at 690 deg.C for 10 hours subsequently, and a superconducting film of onset 110K and a zero-resistance temperature 50K is manufactured.

Title: Vibration-proof device
Inventor: NOGUCHI TAKESHI
IPC: B60K17/22
Filed: 1990-06-22
Abstract: PURPOSE:To maintain stabilized vehicle driving with a spring stiffened when displacement is large and with a spring softened when displacement is minute by dividing all around a hollow chamber formed between an elastic body and an outer cylinder into two chambers, and by enclosing fluid in the chamber surrounded by at least the outer cylinder and a flexible membrane. CONSTITUTION:When a sudden torque variation occurs to an engine an inner and outer cylinders 1, 2 make a large relative displacement, at which time a surface A of the inner circumferencial side of a flexible membrane 5 impinges against an inner wall B of an elastic body 3 and because, when impinged, a fluid L inside a chamber 4 moves toward the opposite side of the place where the fluid L has been impinged, the damping effect and the spring constant can be improved by the fluid pressure variation occurred during the fluid movement. The spring constant, at this time, do not rise suddenly but gradually due to the damping effect effected by the fluid pressure variation. Therefore, an excessive locomotion of a propeller shaft can be restrained immediately. On the other hand, when the vibration is minute, a low spring constant can be maintained because A and B will not impinge against each other. Specially, the existence of a swollen portion 3A, 3B formed on the elastic body 3 is effective to reduce a low noise and the like.

Abstract: PURPOSE:To execute efficient and stable cutting of non-ferrous metals including thick metal plates. CONSTITUTION:Boring is executed under the machining condition A at the point A, and a circular part 31 is formed. Then, the boring operation is switched to the machining condition B where enlarging treatment is executed and an enlarged cut groove 32 is formed in such a manner as the circular part 31 is extended as it is. At the point B, when the enlarging treatment is completed, the stand-off (the distance between the tip of the machining nozzle and the work surface) is set as small as possible, the machining condition is switched to the machining condition C, and the cutting is started under the machining condition C. Thus, cutting is executed in the substantially same condition where the direct cutting is started from the outside of the work end part. During the cutting operation, the pressure of the assist gas is set high, and the stand-off is set small, resulting in more remarkable dross scattering effect. Thus, cutting can be executed in an efficient and stable manner.
