Title: Method for transferring recording medium and system for issuing same medium and constituting part of same system
Inventor: TAKEUCHI TAKASHI
IPC: G06F21/62
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To provide an IC card issuing system for preventing illegality such as the issue of a forged IC card by a person other than a legal card issuer. SOLUTION: A card manufacturer A sets an issuer public key designated as a transportation key from a card issuer B in an IC card. An IC card issuing device enciphers certification data (random numbers) inputted from the IC card by a secret key, and transmits the data to the IC card. The IC card decodes the enciphered certification data by the issuer public key, and certifies the card issuer B based on the decoded result and the original certification data. When the certified result is positive, the IC card issuing device operates the issuing processing of the IC card.

Title: Current vector operation system for induction motor
Inventor: KAIDA HIDETOSHI
IPC: H02P21/22
Filed: 1989-07-03
Abstract: PURPOSE:To improve controlling accuracy and transient stability by operating a delay correction angle for cancelling a calculation delay of a secondary crossing magnetic flux rotating angle, and angle-correcting with the correction angle and the operated rotating angle value. CONSTITUTION:A speed detection value omega'2 from a pulse generator PG is input to a correction angle operator 1. The operator 1 operates a delay correction angle  theta responsive to a following delay time T/2 with respect to a secondary crossing magnetic flux rotating angle theta of a operated rotating angle value theta' as the addition value of the outputs of integrator 14, 17 based on a speed detection value omega'2. When the value theta' and the angle  theta are added by an adder 2 and applied to a vector rotary unit 16 as the operated rotating angle value theta'' (=theta'+ theta) of the secondary crossing magnetic flux, the basic waves of sin theta'' and cos theta'' substantially respectively coincide with sin theta, cos theta. Therefore, the average values of the operated magnetization current Im and a torque current IT coincide with actual values, thereby eliminating the normal deviation of the magnetization current IM, the torque current IT.

Filed: 1984-08-18
Abstract: PURPOSE:To perform an MBE having good crystallinity by sufficiently removing organic contaminants with O3 to clean a substrate, and then growing a crystal without exposing it with the atmosphere. CONSTITUTION:When a substrate 7 is contained in a cassette and inserted from the inlet 8 of an O3 treating chamber 1 into a crystal growing device, it is sequentially transported by a carrier 9 through a dry etching chamber 2 evacuated at 6 in vacuum, an MBE crystal growing chamber 3 and a cassette removing load locking chamber 4, and removed from an outlet. After the chamber 1 is evacuated to 10<-7>-10<-9>Torr, O2 which contains O3 is fed to approx. 0.1Torr, and treated at room temperature for several tens min., an organic compound CnHmOR separates a chemical bond with O3 or O* of excited state to oxidize to remove it from the surface. Thus, the subsequent dry etching effect is improved, the occurrence of a boundary level due to recontamination, the decrease in the crystal purity and the surface defect can be suppressed to perform an MBE having good crystallinity.

Under a condition that feedback control is temporarily stopped, the speed of the engine is continuously controlled. Thereafter, the initial value is gradually decreased with the lapse of time, and control of the speed is returned to the feedback control at a point of time the speed of the engine decreases less than a predetermined idle speed. In this way, an engine stop can be surely further completely prevented.

IPC: G11B20/10
Filed: 1985-08-06
Abstract: PURPOSE:To eliminate a de-emphasis output waveform distortion at reproduction remarkably by setting the amplitude of digital information smaller than the maximum amplitude of analog video information. CONSTITUTION:A clamp output is inputted to an emphasis circuit 4, an output of which causes overshoot or undershoot at rising and falling by high frequency emphasis. When the emphasis output is inputted to a clip circuit 5, the overshoot and undershoot going to twice or over of the maximum amplitude of an analog video signal are clipped and the digital information is led out without being clipped. The clip output is inputted to a FM modulation circuit 6, inputted to an optical modulator of an optical video disc recorder together with a pilot signal for jitter correction and a recording track is formed on a video disc record. Thus, the waveform distortion of the reproduced digital information is eliminated.
