Patent JP-H04246909-A (JP)
Title: Semiconductor device
Inventor: IGARASHI HATSUHIDE
IPC: H03K17/687
Filed: 1991-02-01
Abstract: PURPOSE:To obtain a semiconductor device which is operated at a high speed, in which a noise due to the switching of an output signal is extremely small as a whole. CONSTITUTION:The output signal of a semiconductor device is divided into an active high control signal system, a data signal system which frequently repeats a level change, and an active low control signal system. The high level of the former signal system is sharply reduced compared with a power source potential by a first output circuit 3 so that the driven current of a load can be halved, and the noise generated at the time of the switching of the output signal can be sharply reduced. On the other hand, only the high level of the active low control signal system is turned to the power source potential by a second output circuit 4. Therefore, the switching noise due to the output signal of the data signal system which frequently repeats the level change or the like, can be sharply reduced.

Title: Heat sink
Inventor: TOMOHIRO TERUHIKO
IPC: H01L23/36
Filed: 1992-01-27
Abstract: PURPOSE:To provide a heat sink for cooling a semiconductor device without increasing its size by producing uniform flow velocity of air through all fins to maximize the cooling effect of the fins. CONSTITUTION:A heat sink has a base 4 in the form of a plate or bar, from which a plurality of fins 5 of different thicknesses extend at regular intervals. The fins are thickest at both ends and thinnest at the center. Therefore, the distance between faces of adjacent fins becomes wider toward the center. This increases the flow velocity of air through the middle fins, thereby improving the cooling characteristic.

Title: Integrated circuit substrate for active panel
Inventor: OZAKI NOZOMI
IPC: H01L21/82
Filed: 1983-01-27
Abstract: PURPOSE:To reduce an exposed silicon-substrate surface to which beams directly collide, to inhibit an intrusion of beams and to minimize optical leakage currents by constituting two power supply lines so as to pass through between each of adjacent picture element electrodes. CONSTITUTION:A power supply line (VSS)48 wired in a P well is shared by picture elements 46, 47, picture elements 47, 49 have similar relationship, and a power supply line (VDD) wired on an N type substrate is also shared.

Title: Method for engaging wire rope and its device
Inventor: ITO MASASUKE
IPC: F16G11/00
Filed: 1986-01-24
Abstract: PURPOSE:To simplify a method for engaging a wire rope and make its device smaller and lighter by forming the end of a wire rope in a protrudent shape to serve as an end protrusion, and threadedly attaching a rotatable cap nut on a stud bolt fixed to a body to be engaged. CONSTITUTION:A sleeve 7 is fixed with pressure to the end of a wire rope 1, and molten metal is impregnated into them to form an end protrusion 2. The end protrusion 2 of the wire rope 1 and a cap nut 3 are kept in a combined state, and in using them, the cap nut 3 is threadedly attached on a stud bolt 5, and then locked with a lock nut 6. Because of frequent change in the tractive direction of the wire rope 1, the external surface of the end protrusion 2 and the internal surface of the cap nut 3 are shaped into a ball to produce self- aligning action, and thereby the fatigue of strands at the neck part of the wire rope where stresses are liable to concentrate can be prevented. Since the stresses caused in an engaging device are only the tensile stress in the wire rope 1 and the shearing stress occurring partially in the end protrusion 2 and the cap nut 3, the engaging device can be wholly miniaturized.

Title: Reception circuit for fm multiple signal
Inventor: KIMURA KAZUHIRO
IPC: H04B1/26
Filed: 1995-01-27
Abstract: PURPOSE: To reduce the cost by sharing a used clock oscillator among a PLL frequency synthesizer circuit, a filter circuit which samples a digital signal frequency band after FM detection, and a digital detection circuit. CONSTITUTION: A PLL frequency synthesizer circuit 3 is operated in accordance with the frequency of the carrier signal sent from a selected broadcast station. After the intermediate frequency signal obtained based on the frequency of this carrier signal and the output frequency of the synthesizer circuit 3 is subjected to FM detection, the frequency band of the FM multiple digital signal is sampled by a switched capacitor filter 21. A delay detection circuit 42 restores a digital signal from the sampled frequency band. The frequency of a clock signal CLK used for the switched capacitor filter 21 and the delay detection circuit 42 is equal to the oscillation frequency (for example, 7.2MHz) of an oscillator 4, and it can be shared. Thus, the cost is reduced and the problem of unnecessary radiation of the oscillator is resolved.

Title: Pouring method of oxygen into feed water for boiler
Inventor: TSUBAKISAKI SENICHI
IPC: F22D11/00
Filed: 1993-01-28
Abstract: PURPOSE:To provide a method capable of retaining an objective concentration correctly while coping with the change of dissolved oxygen concentration in feed water for a boiler with good response property. CONSTITUTION:Oxygen gas is poured into the feed water system for a boiler from an oxygen bomb 5 through an oxygen gas flow rate regulating valve 4 and an oxygen gas intercepting valve 3. The amount of poured oxygen gas is determined in proportion to the flow rate of the feed water based on a difference between the concentration of dissolved oxygen in the feed water, which is detected by a dissolved oxygen meter 2' installed in the upstream of a pouring point, and the set value of dissolved oxygen concentration. The proportional control is effected employing a dissolved oxygen concentration signal in the upstream of a pouring point in such a manner whereby the pouring of oxygen, coping with the sudden fluctuation of the dissolved oxygen concentration in the feed water, can be effected.

Title: Anti-lock control device
Inventor: TAKAHIRA YOSUKE
IPC: B60T8/1764
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To reduce the braking distance when deceleration of an automobile body is small in an anti-lock device performing low selecting control about right and left front wheels. SOLUTION: Compared with an usual control controlling braking pressure of the either front wheels each other independently a low selecting control and control mode change type control are selectivity performed (S3-S7) as a control method restricting the difference of right and left braking force, because of a strong request to restrain the vehicle deviation based on the difference of the braking force of either front wheels when the body deceleration at the time of braking is large and the tire lateral force of either rear wheels is lowered based on the lowering grounding load of the either rear wheels. On the other hand, when the body deceleration at the time of braking is small, the grounding load of the either rear wheels is not lowered so much and the requests to restrain the automobile body deviation are not strong, so the usual control (S3, S8) is performed.  Therefore, when the automobile body deceleration is small, the braking force of the either front wheels is prevented to become smaller than necessary, so the braking distance can be reduced easily.
