Title: Head position correction control system for disk storage device
Inventor: KAWAHARA YUJI
IPC: G11B21/10
Filed: 1990-05-22
Abstract: PURPOSE:To prevent the generation of write/read error by correcting a position designation signal to be applied to an actuator based on the amount of offtrack detected at that time and the stored content of functional relation. CONSTITUTION:By a correction function calculation means 20, the amount of offtrack is detected by shifting a position designation signal S to an actuator 4 from the predetermined value successively by plural tracks T in a disk 1 during non-read/write operation of the disk stored device. From the result, the relation between a correction value for the position designation signal S and the amount of offtrack delta is stored after calculation, and the position designation signal S is corrected based on this stored content and the amount of offtrack delta by a position correction means 30 at the time of the read/write operation. Thus, the position correction control to a head 3 is always kept with high-accuracy and the generation of read/write error is prevented.

Title: Manufacture of germanium-gallium arsenide junction
Inventor: KAWANAKA MASAFUMI
IPC: H01L21/203
Filed: 1989-05-26
Abstract: PURPOSE:To enable germanium films in high purity and excellent crystallizability to be formed by a method wherein a germanium film is thinly deposited at the first lower substrate temperature on the arsenic stabilized surface of a gallium arsenide substrate and then another germanium film is deposited at the second higher substrate temperature. CONSTITUTION:An n type gallium arsenide epitaxial layer 2 is deposited on an n type gallium arsenide substrate 1 and after the appearance of a stabilized surface of arsenic, a germanium layer 3 is deposited at low temperature. Successively, the substrate temperature is raised; another germanium layer 4 is deposited while doping it with gallium; the substrate 1 is exposed to the atmospheric air; and then an electrode 5 is formed by patterning and etching processes. Thus, the substrate temperature is reduced to lower level and the germanium is so thinly deposited that the diffusion of arsenic from the gallium arsenide may be avoided while the unsatisfactory crystallizability due to the lower substrate surface temperature can be recovered by the heat treatment at high temperature to be performed later. Through these procedures, germanium films in high purity and excellent crystallizability can be formed.
