Title: Printed wiring board and production thereof
Inventor: WATANABE YOSHIO
IPC: H05K3/24
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To increase the production yield while enhancing the characteristics by forming a wiring circuit pattern having a land part on an insulating board and then forming solder bumps on the land part before forming a protective layer of a metal baser than the solder between the land part and the bump. SOLUTION: A wiring circuit pattern 2 having a land part 2a is formed on the major surface 1 of an insulating board 1 and a protective layer 3 is formed at a predetermined position of the land part 2a before forming solder bumps 4 thereon. The protective layer 3 is composed of a metal nobler than solder, e.g. gold or palladium, and the land part is protected against electroless solder plating during the electroless solder plating step. An underlying layer 5 of nickel, for example, stabilizes adhesion between the protective layer 3 and land part 2a.

Title: Plate thickness control method
Inventor: MITSUYOSHI SADAYUKI
IPC: B21B37/18
Filed: 1985-09-24
Abstract: PURPOSE:To improve plate thickness accuracy by obtaining a plate thickness deviation at the outlet side of a rolling mil based on a difference between a stored criterion tension value and a detected tension value and controlling a rolling speed so as to make the above deviation zero. CONSTITUTION:A tension meter 20 and a thickness meter 22 are installed in the outlet side of the 1st-6th rolling mill line and a cutting position detector 24 is installed in the inlet side of the above rolling mill line. When a strip 10 is continuously rolled and is wound by a reel 16, a controlling computer 30 tracks a cutting position of the strip 10 and stores a criterion tension value (tb*) by taking in the value from the tension meter 20. A plate thickness controller 32 obtains a plate thickness deviation and calculates a speed variation DELTAV and inputs the variation into a sped controller 36 at the time when the strip 10 is cut. Then, the controller 36 drives a motor 23 and controls a roll speed V6 so as to make a plate thickness deviation of the strip 10 zero based on a signal of the speed variation DELTAV. In this method, a plate thickness accuracy is improved.

Inventor: FUJII YOSHIKAZU
IPC: G11B7/09
Filed: 1983-11-09
Abstract: PURPOSE:To improve the resistance to external vibration by providing a compensation circuit providing phase lag compensation to increase the gain at a frequency band up to the resonance frequency to the control current of a linear motor. CONSTITUTION:The resonance frequency omega0 of a transfer function G0 of a radial actuator or a linear motor to displace an objective lens in radial direction in a radial control system is a disc turning frequency or over. Furthermore, the compensation U is the phase lag compensation increasing the gain of the frequency band from a low frequency (DC component) to the resonance frequency. The open loop transfer function G and the stiffness S against external disturbance from the transfer function of the compensation U are obtained respectively from Equation. Thus, the performance of the stiffness S is improved in comparison with that of a conventional radial control system at a frequency being the cut-off frequency omegac or below in this way. Since the omega0 is higher than the disc turning frequency, the performance of the stiffness to external disturbance in the disc turning frequency is improved in comparison with that of the conventional radial control system.
