Title: Optical mask and method for correcting its defect
Inventor: HAIRI ISAMU
IPC: G03F1/68
Filed: 1992-10-21
Abstract: PURPOSE:To prevent a transfer of a defective part on a wafer even when a defective part generated on a phase shifter is corrected by interposing a prescribed transparent film between an optical mask substrate and a phase shift for giving a phase difference to a transmitted light. CONSTITUTION:On a quartz substrate 11, a light shielding pattern film 12 consisting of chromium and an etching stop layer 13 which is consisting of aluminum oxide and covers the film 12 are formed. On the etching stop layer 13, the transparent film 14 consisting of silicon oxide is formed by applying a vapor deposition method. Moreover, the transparent film 14 affords the 90 deg. phase difference when i line (365nm) is used. When the phase shifter 15 consisting of silicon oxide with, for example, 3800Angstrom thickness is formed on the transparent film 14 by applying a resist process, a vapor deposition method and a lift-off method in the lithography technique to prepare a phase shift optical mask, a defective part 15A is generated in the phase shifter 15. The phase shifter 15 in a normal case affords a 180 deg. phase difference when i line is applied.

Title: Tape driver with arc-shaped scanner and method for calibration of said arc-shaped scanner
Inventor: RICHIYAADO KEI MIRO
IPC: G11B5/008
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To accrately perform the changeover between the read timing and write timing and between these read and write operations by providing a control structural body combined with the arcuate scanner and an inclined controller for positioning control of the arcuate scanner. SOLUTION: The control structural body 46 is equipped with a traveling time decision circuit 52, a positioning error decision circcuit 50 and a calibration unit 54. A 1st traveling time of one of arcuate scanner heads of the arcuate scanner 10 in the upper part of a scannable line of a magnetic tape and a 2nd traveling time of the lower arcuate scanner head are decided by the traveling time decision circuit 52. The 1st and 2nd traveling times are compared with each other by the positioning error decision circuit to generate a positioning control signal to enable the inclined controller 48 to control a positioning error amt. of the arcuate scanner 10 in the recording tape to be substantially zero.  When the positioning error is zero, a 3rd traveling time of the scanner head from a prescribed rotary position to the scannable line is decided, and the timing for the read and write operations and their changeover are calibrated by the calibration circuit 54.

Title: Device and method for controlling software parts
Inventor: OKU TOMOO
IPC: G06F9/06
Filed: 1989-10-30
Abstract: PURPOSE:To speed up the reading process of software parts by forecasting a parts group having high probability of succeeding reference by using a reference stack and storing and controlling the forecasted parts group in a cache. CONSTITUTION:In the case of extracting software parts from a parts data base, the number of accesses to a storage device 11 can be reduced by previously storing relating parts in the cache 15. Namely, all method parts having the same target for a software parts group grouped as parts by target directivity are regarded as relating parts, and when the input request of method parts for one target is generated, other method parts having the same target name are previously read out and controlled in the cache 15. When the succeeding parts reading request is generated, data are transferred from the cache 15 without accessing the storage device 11. Thus, I/O operation is rapidly executed.

IPC: B21D37/14
Filed: 1990-10-22
Abstract: PURPOSE:To simplify the mechanism of structure by providing a pin wherein its point is set retractably and obliquely to the side of a die on a mounting surface and a tapered part possible to abut on the side wall of the die is set at the tip part and a pin pushup part pushing up said pin and holding it on the mounting surface under pressure.
