Title: Binary signal transmitter
Inventor: UMEBAYASHI KAZUYUKI
IPC: H04L27/10
Filed: 1983-03-01
Abstract: PURPOSE:To prevent a transmission error even when a power source line is used as a transmission line by specifying the pulse width at a transmission side, and shifting the appearance timing of an unnecessary wave component forward and masking signal detection on a reception side for a specific time. CONSTITUTION:A pulse signal with a constant period is outputted to the output terminal DOHA of an FSK modulator 100 according to transmit data and a monostable multivibrator MM1 outputs a pulse signal having width far shorter than the width of the pulse from the DOHA. Then, TRs Q1 and Q2 turn on and off alternately by this signal and differential pulse signals with the positive and negative polarities appear on an AC line and boosted in voltage by a pulse transformer PT. In this case, a ringing waveform appears at the output of a PT following the differential pulse signals. Therefore, a monostable multivibrator MM2 masks signal detection for a time TC when a pulse appears as a differential pulse signal to prevent erroneous detection due to the ringing waveform.

Title: Io bridge
Inventor: EGUCHI HIROYUKI
IPC: G06F13/36
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To improve the throughput of an IO bus. SOLUTION: At a request to transfer data from an IOC 60-i (i=0-n), the IO bridge 50 reads the requested data out of a MEM 30 and sends them out. In this case, when one of IOCs makes a request transfer data, a retrial instruction as to the request is sent out to the IOC. Then the transfer request from an IOC which has made a transfer request after the instruction transmission is masked. Data regarding the transfer request after the instruction transmission are prepared in an internal buffer and the request is unmasked when the preparations are completed. Consequently, a write transfer request from another low-order device can be accepted in the period wherein the request is masked. In a system which use write transfer frequently, the occupation of a bus for read transfer is reducible and the throughput of the IO bus can be improved.

Title: Universal reluctance motor
Inventor: KUKIHARA TAKEAKI
IPC: H02K23/64
Filed: 1995-01-12
Abstract: PURPOSE: To obtain a universal motor having a field requiring no winding nor permanent magnet by a structure comprising a salient pole field and an armature with commutator wherein the brush angle is shifted from the neutral axis the field is excited principally with the magnetic force of the armature. CONSTITUTION: An armature winding 6 is fed with a current through a brush and a commutator as shown on the drawing. Unmarked armature winding indicates zero current. When an armature current is fed while shifting the brush angle 5 from the neutral axis 3, the field is also excited with the armature current. Consequently, the field does not require any winding or permanent magnet but requires only a salient pole. Since the rotation is not reversed even when the polarity of current is reversed, a universal motor is obtained.

Title: Base rock sound measuring device
Inventor: PEETERU FUSUTEN
IPC: G01V1/52
Filed: 1985-02-22
Abstract: The acoustical measuring device consists of a measuring probe which is immersed by means of a cable in the bore hole filled with drilling medium and can be moved in the axial direction therein. The measuring probe contains a transmitter which emits pulses. The echo signals are detected by a receiver fitted in the measuring probe. To detect the geophysically particularly important casing waves, which are received as strong useful signals undisturbed by transient and decay processes, the effective distance between transmitter and receiver in the measuring probe is smaller than half the wavelength of the signal transmitted in the drilling medium. This involves a reflection arrangement of essentially axial oscillators which are broad-band but prefer the lower acoustical frequency range. The measuring time of the sonograms received (microseismograms) is up to about one second.

Title: Electric brake device for electric rolling stock

IPC: B60L7/22
Filed: 1982-03-05
Abstract: PURPOSE:To enable to rise a regenerative current rapidly when a regenerative load at a trolley wire side is recovered and a pantograph isolation is recovered by varying the control of the regenerative current by the compared result of the voltage of a filter capacitor with each set value. CONSTITUTION:A regenerative current limiter 20 operates a regenerative chopper 8 to suppress the current of a motor 2 when the voltage VC of a filter capacitor exceeds a set value V1, and when the voltage VC reaches the set value  V2, the limiter generates the maximum limiting output. A comparator 21 operates a resistance chopper 5 when the voltage VC reaches V3(V3>=V2) and resets the chopper to OFF state when the voltage VC becomes lower than V0(V0<V1). A pattern generator 23 generates the pattern IRP of a current IR which is flowed through the chopper 5 in response to the regenerative current IL. In this manner, stable brake force is controlled while suppressing the overvoltage of the filter capacitor.

Filed: 1987-02-20
Abstract: PURPOSE:To obtain a resist pattern having high aspect ratio by radiating light on a prescribed pattern composed of a nonoxidative material or a material capable of changing to a nonvolatile oxide by an oxidation reaction which is formed on an org. substance layer, in an oxidative atmosphere, followed by removing the exposed org. substance layer by photooxidation-etching. CONSTITUTION:The resist film of the org. substance layer is formed by applying the positive type photoresist of naphthoquinone diazide OFPR-800 on for example, a silicone substrate, followed by baking the obtd. substrate. Subsequently, a prescribed test pattern is exposed on the resist film, followed by developing the exposed resist film to form the resist pattern on the upper layer of the substrate, followed by photooxidation-etching the obtd. substrate. As the upper layer pattern 3 contains silicon, the film of the nonvolatile silicon oxide is formed on the upper layer pattern by the photooxidation whereby the further etching of the upper layer pattern does not advance. While the surface of the resist film 2 of the org. substance layer which is not coated with the upper layer pattern 3 contg. silicon, absorbs effectively an exposure ray and is effected the photooxidation-etching, successively whereby the etching of the resist film advances until the silicon substrate. Thus, the underlayer resist pattern having high aspect ratio is formed.

Filed: 1995-02-23
Abstract: PURPOSE: To energize electricity with improved dust collecting performance by a method wherein change of electric resistance of dust with time is calculated in accordance with a preset burning plan and based on the relation between the value of electric resistance and the set value of electric charge, switching between pulse electric charging and continuous charging and control of base electric voltage and pulse electric voltage in pulse electric charging are performed. CONSTITUTION: Change of electric resistance of burnt ash with time is calculated by a computor 20 based on a predetermined burning plan of coal. Then, the calculated result is divided with time by a control period and is stored in a data file. Then, electric resistance of dust at the present control period and electric resistance of dust after X hours corresponding to the next control period are read out to compare both values of electric resistance. Based on the result of comparison, a control panel 19 for energizing of electricity and a high voltage electric source 25 are controlled. For example, when both electric resistances are equal, pulse electric changing is performed and reverse ionization phenomenon is suppressed. In addition, when the electric resistance is smaller than about 10<11> Ω.cm, continuous electric charging is performed.
