Abstract: PURPOSE:To enable a roll die for an optical recording medium to be manufactured by a simple mechanism and with high accuracy, by a method wherein working of a stamper and fixing of the stamper to a forming roll are carried out through a jig having a recessed surface with a diameter matched to the forming roll. CONSTITUTION:A protective layer 2 is formed in a predetermined thickness on a surface of a stamper 1 provided with a rugged pattern 3 such as a pre- format pattern on the surface thereof. The stamper 1 is attached through the protective layer 2 to a jig 4 having a cylindrically recessed surface with a diameter matched to a forming roll, and the back surface of the stamper 1 is worked so as to provide the stamper 1 with a fixed thickness over the entire surface thereof.

Title: Automatic/manual switching device of controller
Inventor: NAKAGAWA KAZUYOSHI
IPC: G05B7/02
Filed: 1979-12-14
Abstract: PURPOSE: To realize a quick switching from the manual output value to the controller output value, by holding the difference between the manual output value and the controller output value at a capacitor during the manual operation and then starting a discharge when the manual operation is switched to the automatic operation.  
     CONSTITUTION: During the manual operation, the switches SW 3 WSW 5  are set at the H side with the switches SW 1  and SW 2  closed respectively by the output given from the manual operation part MO. The reversible counter CNT performs the up- or down-counting by the manual operation signals MS 1  and MS 2  supplied from the part MO. Thus a manual operation is given to the operation part OP. The manual operation signal VH is applied to the differential amplifier OA 1  along with the automatic output signal VA given from the controller, and the difference between both signals is stored in the capacitor C. In this case, the output of the differential amplifier OA 4  is already zero, and accordingly no bump is caused even if the switches SW 3 WSW 5  are switched to the side A. When the manual operation is switched to the automatic operation, the capacitor C discharges gradually. As a result, the output of the operation part coincides gradually with the signal VA.

Filed: 1979-12-15
Abstract: PURPOSE: To increase the etching speed and enhance the productivity by exposing an oxide dielectric plate to a surface of a grounded electrode opposite to a high frequency application electrode to keep the potential of a sample equal to that of the grounded electrode.  
     CONSTITUTION: Sample 28 is fixed in the hole punched in oxide dielectric plate such as quartz plate 29 so that it contacts with metal flat plate 30.
