Title: Method for peeling silicon-wafer protective masking sheet
Inventor: KI MASAHIRO
IPC: H01L21/78
Filed: 1986-06-30
Abstract: PURPOSE:To satisfy the requirement for automation as well as to enable the masking sheet to be peeled from a silicon wafer more reliaby by peeling the masking sheet substantially in parallel with the sheet surface, and, in failure of peeling, applying a new peeler tape again and retrying the peeling. CONSTITUTION:A peeler tape 3, which is applied to a wafer-protective sheet 2 of a silicon wafer 1 sucked and fixed by a vacuum table 7, is positionally fixed through the lower circumferential portion of a pressing roller 4 and the upper circumferential portion of a take-up roller 5, and thereafter the pressing roller 4 and a take-up roller 6 are moved back in the direction of arrow G substantailly in parallel with the sheet surface of the wafer-protective sheet 2. Since, in this process, the peeler tape 3 is taken up onto the take-up roller 5 and is in under tension, the wafer-protective sheet 2 peels from the silicon wafer because it is adhered at the peeler tape paste surface 3' of the peeler tape 3. And if the peeling of the wafer-protective sheet 2 is failed, the pressing roller 4 is moved again in the direction of arrow B to feed the peeler tape 3, and a new peeler tape 3 is applied. Then, this process is repeated again to retry the peeling.

IPC: H04N5/92
Filed: 1988-06-21
Abstract: PURPOSE:To easily distribute time adjustment R, G, B signals to 4 magnetic heads in a prescribed order by applying 2/3 time compression to the R, G, B signals and generating the time adjustment R, G, B signals having a time difference of 1/3 field mutually. CONSTITUTION:After R, G, B signals are converted into digital signals by A/D converters 26a-26c, they are subjected to 2/3 time compression by time compression circuits 27a-27c each comprising a memory and become signals B, D, G. Since a tape 11 is wound on a drum 10 by somewhat over 180 deg., heads 7a-7d are in contact onto the tape 11 by somewhat longer than nearly 11.1msec. Thus, the R, G, B signals of one field (16.67msec) are subjected to 2/3 time compression by time compression circuits 27a-27c to form a time of 11.1msec thereby enabling the signal by one field to be recorded by one head.

Title: Tape-like recording medium reproducing device
Inventor: WAKIYAMA KOJI
IPC: G11B15/467
Filed: 1988-06-22
Abstract: PURPOSE:To reduce the deterioration of a tape material and the abrasion of a head by making a speed component in the direction of track of the head constant when a tape traveling speed falls within a specific range and making the number of revolutions of a rotary cylinder constant when the speed falls outside the range. CONSTITUTION:When the traveling speed of a magnetic tape 1 detected by a tape speed detecting means 6 falls within the specific range, an output of the detecting means 6 is outputted as it is by an output limiting circuit 7, and an error value between an output value corresponding to the number of revolutions of the rotary cylinder 3 outputted from a revolution detector 4 and an output value corresponding to the tape traveling speed outputted from a memory circuit 8a is outputted by a subtraction circuit 8b, and then rotation torque is generated in proportion to the error value by a cylinder driving circuit 8c to control the rotation of the rotary cylinder 3. ON the other hand, when the tape traveling speed falls outside the specific range, a constant digital signal is outputted by the output limiting circuit 7, and hence the rotary cylinder 3 is rotated at a prescribed constant number of revolutions by the memory circuit 8a, so that although the readout of tape positioning information is not compensated, the deterioration of the tape material and the abrasion of the head, etc., are hence reduced.
