摘要： An electric contact with a base metal used as a switch wherein the non-welded peripheral portion of the contact is prevented from bow-like bending and from peeling off. The electric contact with a base metal having a contact promoting shape is formed by die forging of a contact material joined to the base metal by resistance welding. The composite contact material is prepared by coating the core material of Ag-oxide contact material with non-oxide contact material. The side of the material in contact with the base metal is of non-oxide contact material. The contact material may be pressed to fill a groove preformed in the base metal, welded to protrusions preformed in the base metal, welded to the bottom of a cut preformed in the base metal, or welded to bottoms of recesses preformed in the base metal.

摘要： A signal processing device for analog-to-digital converting a burst signal has a feature of selecting a data bus to notify a disk control device of a conversion result via an NRZ data bus. The disk control device stores the result of the analog-to-digital conversion of the servo positional signal. The positional signal of a head of the disk device is digitalized in a R/W channel. Sampling for digital conversion is performed in only a window which is defined only in the vicinity of peaks of the positional signal. The values of peaks which are obtained by sampling are averaged by an averaging circuit. This enables the influence of noise occurred outside of the window to be eliminated. Although the noise in the window is sampled, its adverse influence is suppressed by the averaging processing.

摘要： A signal processing delay circuit is fabricated as a semiconductor integration circuit to cope with increase in the data transfer speed and data recording and reproducing density on a recording medium. In the delay circuit, the amount of delay of a reference delay circuit of a delay PLL is controlled to take a fixed value independent of deviation in quality of the semiconductor circuit, change in power, and alteration in temperature. A control signal supervising the delay amount of the reference delay circuit is employed to control amounts of delay of input signals supplied to a window adjustment delay circuit of a window adjustment circuit and a T/2 generation delay circuit generating a synchronizing signal. Each of these delay circuits includes an analog variable delay circuit having the same configuration. The window adjustment delay circuit is supervised by a signal obtained by weighting the control signal by a D/A converter. A data acquisition circuit and a data write circuit each include an analog variable delay circuit.
