Title: Emphasis/de-emphasis device
Inventor: NISHIDA YUKIHIRO
IPC: H04N5/20
Filed: 1990-07-17
Abstract: PURPOSE:To supply a sufficient amount of emphasis without worrying about the generation of signal distortion by returning the output signal of a non-linear circuit added while positioned after the emphasis circuit successively through corresponding other reverse non-linear and de-emphasis circuits. CONSTITUTION:The recovery output signal of a transmission side post de- emphasis device is returned to the input edge of a P circuit 7 in the emphasis device, and an input signal in the past on this kind of emphasis circuit is formed based on the recovery output signal including the waveform distortion. In the reception side emphasis device, the correction processing, corresponding to the performance of the de-emphasis processing to the amplitude recovery output signal including the waveform distortion generated by the non-linear/reverse non-linear processing, is performed to the input signal before the emphasis processing in the emphasis device on the transmission side, and the waveform distortion generated in the recovery output signal caused by the non-linear/ reverse non-linear processing is offset and eliminated.

Abstract: PURPOSE:To precisely and easily carry out troublesome setting of motor constant by identifying secondary resistance by way of using secondary circuit time constant of phase difference of zero and magnetization inductance of amplitude difference of zero. CONSTITUTION:A magnetic flux computing part 116 is changed over to three constitutions of tuning of phase discrimination, secondary circuit time constant and magnetization inductance. At the time of phase discrimination, phase and direction are found in relation with a speed controller 101, a sinusoidal wave generator 121 and a two phase/three phase converter 106. Thereafter, in a tuning mode of the secondary circuit time constant, as two outputs of the sinusoidal wave generator 121, sinusoidal wave of 90 degrees phase difference of Sin wave and Cos wave is generated. Thereafter, inverse value of the secondary circuit time constant is measured by an internal mechanism of the magnetic flux computing part 116. At last, in a tuning mode of the magnetization inductance, the Sin wave from the sinusoidal wave generator 121 is input to the internal mechanism of the magnetic flux computing part 116. Thereby, the magnetization inductance is measured, and from a coefficient multiplier, secondary resistance is found.

Title: Method for joining members
Inventor: IKEDA TOMOO
IPC: C25D1/00
Filed: 1999-07-02
Abstract: PROBLEM TO BE SOLVED: To carry out joining suited to vacuum parts as well as fine parts with low heat resistance by bringing a second member into contact with a first member with electric conductivity and forming an electroforming layer on the first member in the above state to fix the second member to the first member. SOLUTION: A second member 2a, composed of glass or ceramic material of about 0.3 mm thick, is disposed in an arbitrary position of a first member 1a composed of copper sheet with electric conductivity so that they are in contact with each other. In this state, an electroforming layer 3a composed of nickel, etc., is grown by means of electroforming on the first member 1a to about 35 mm thick, by which the second member 2a can be fixed on the first member 1a. Because the electroforming layer 3a can be formed at a temperature as low as about 20-80 deg.C and requires no high-temperature steps for joining, even materials with low heat resistance can be bonded. Further, because joining is performed by using the electroforming layer 3a composed of metallic material, corrosion resistance superior to that of an adhesive can be provided and this joining method is suitable for joining of vacuum parts.
