Title: Drive control method for step motor
Inventor: WAUKE ASAKUNI
IPC: G11B21/08
Filed: 1990-07-19
Abstract: PURPOSE:To minimize hysteresis by providing first exciting step for stopping a step motor at a target track, second exciting step for moving the step motor over the dead zone thereof, and third exciting step for positioning the step motor on the end side in the dead zone. CONSTITUTION:A step motor has four exciting phases A, A', B, B' and two of them are excited. In an example, the step motor is stopped at a target track in A' and B phases. When a head is once positioned on the target track, adjacent exciting phases, i.e., A' and B phases, are then excited for 0.275mS thus temporarily bringing the head to the outside of an external load region(dead zone) W. Target tracks, i.e., A', A' phases, are then subjected to chopper excitation for 38.40muS with a rate of 1:5 thus bringing the head back to the target track with weak force. Consequently, the head stops in a stable position in which the potential is minimum at the end in the dead zone.

Title: ArF POSITIVE TYPE PHOTO-IMAGE FORMING COMPOSITION
Inventor: ICHIMURA KUNIHIRO
IPC: G03F7/039
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To enhance transparency, sensitivity, dry etching resistance, adhesion and resolution by using a new acrylic copolymer having a thiophene residue and an ester residue introduced into a side chain. SOLUTION: The ArF positive type photo-image forming composition contains a copolymer obtained by copolymerizing a 2-thienylalkyl (meth)acrylate and a (meth)acrylic ester and a photo-acid generating agent as essential components. The photo-acid generating agent is 4-phenylthiophenyldiphenylsulfonium hexafluoroantimonate. When an acid propagator is further contained, a proton formed from the photo-acid generating agent acts catalytically to the acid propagator and a large quantity of a new strong acid is released in geometric progression. By the catalytic actions of all the acids, ester groups such as tertiary alkyl ester groups in the acrylic copolymer cause elimination and become (meth)acrylic acid groups by accelerative degradation, accordingly sensitivity is enhanced.
