Title: Recording equalizing method for digital signal
Inventor: SAKATA HARUO
IPC: G11B5/09
Filed: 1986-01-31
Abstract: PURPOSE:To raise the level sufficiently even in a high frequency area by allowing a square wave signal to have a waveform, which is changed in positive and negative directions symmetrically with the time base as the center, when a digital signal which is emphasized near the rise part and the fall part of the square wave signal to be recorded is equalized. CONSTITUTION:A square wave signal Si having a waveform (a) inputted to a low-pass filter 2 is corrected to a signal S2 having a waveform (b) by a delay line 3 connected in parallel with the filter 2, and these two signals are applied to a differential amplifier 4 to obtain a correction signal S3 having a waveform (c). A gain control circuit 5 is used to control the gain by alpha, and the output of this circuit 5 and the output of the delay line 3 are applied to an adder circuit 6 to obtain an added signal S4 having a waveform (d). Thus, the signal S4 has the waveform where edge components corresponding to alpha/2 are added near the rise part and the fall part of the signal S1, and this wavevofm is changed in positive and negative directions symmetrically with the time base as the center. Thereafter, edge parts are cut by beta/2 to obtain a signal S5.

Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a plating layer, and to prevent the deterioration of the corrosion resistance, by forming an urethane resin film including a specific amount of chrominum and a specific amount of resin powder, on the surface of a Zn system alloy plating steel plate to which a Zn-Mg alloy plating having a specific Mg inclusion is applied on one side surface. SOLUTION: To the surface of a Zn system alloy plating steel plate to which a Zn-Mg alloy plating with 1-20mass% of Mg content is applied 10 to 50g/m<2> per one side surface, an urethane resin film including 10 to 100mg/m<2> of chromium, and 2 to 25mass% of resin powder having the melting point more than 100 deg.C, is formed 0.5 to 2.0μm. Since the plating layer is a Zn-Ng alloy having a corrosion resistance in such a structure, it has a degraded gasoline resisting property and a salt damage resisting property, even though the thickness of the plating layer is made thinner, and a resistant welding property and a press processing efficiency can be improved. And, the chromium in the urethane resin film improves the degraded gasoline resisting property and the salt damage resisting property, and the resin powder is projected from the coating so as to exercise a lubricating function.
