Title: Read after write circuit
Inventor: ITO YASUAKI
IPC: G11B20/18
Filed: 1993-01-22
Abstract: PURPOSE:To sufficiently guarantee the recorded data of an information recording/reproducing device, for example, an optical disk characterized by a minute amplitude deterioration of a reproducing signal. CONSTITUTION:When a read after write processing is carried out, at a phase error detection circuit 108 phase relations between a data clock signal 204 and data signals 201 and 203 are checked by flipflops 112 and 113 and a logical gate 114. A rate setting for the discriminating window of a checking value is carried out by setting the delaying time of delaying circuits A 109 and B 110 for delaying a data signal. When the frequency of the data clock signal is changed, the delaying time of the delaying circuits A 109 and B 110 is controlled and a constant rate of margin is secured for the discriminating window.

Title: Discriminating method for propriety of caulking
Inventor: INOUE IWAO
IPC: G01R31/04
Filed: 1981-01-23
Abstract: PURPOSE:To judge whether contact pressure is high or not, by discharging the residual stress of the plastic deformation part of a terinal by a heat shock etc. and then by measuring contact resistance. CONSTITUTION:The relation between caulking pressure and contact resistance is as shown in a figure A, and a difference in contact resistance is generated depending upon the variance of a press impact degree and the kind of material plating on a faying surface. When only the terminal part of a sample is dipped in a 330 deg.C solder deep vessel for five seconds and a heat shock is applied to the faying part, the result in a figure B shows a smooth curve and the contact resistance varies with the caulking pressure, but the relational expression of the contact pressure and contact resistance is not coincident. Namely, when the caulking pressure and contact pressure increase above some pressure at a caulked part, the contact pressure becomes constant. For the discrimination of the propriety of the caulked part, the heat shock is applied to the caulked part and the contact resistance is measured, thus judging whether the caulking state is normal or not.
