Title: Thin film magnetic head
Inventor: WADA YOSHITAKA
IPC: G11B5/31
Filed: 1985-12-18
Abstract: PURPOSE:To prevent the formation of a diffused layer at the boundary between a ferromagnetic oxide substrate and lower magnetic film so as to decrease the influence of a pseudo gap and to obtain a head which has an excellent electromagnetic conversion characteristic and permits good recording and reproduction by interposing a reaction-preventive film consisting of an oxide material to the boundary face between the thin ferromagnetic metallic film and lower magnetic film. CONSTITUTION:The composite substrate interposed with the oxide film 2 as the reaction-preventive film at the boundary face between the ferromagnetic oxide substrate 1 and the lower magnetic film 3 is used. An oxygen compd. such as SiO2 is used as a material for the oxide film 2. The film thickness d1 of the oxide film 2 is preferably in a 50-500Angstrom  range. More specifically the oxide film 2 acts as the pseudo gap and the swell in a 7-11MHz frequency increases to >=2dB if the film thickness d1 is made >=500Angstrom . Such leads to the deterioration of a reproduced image and is undesirable. The effect of preventing reaction at the boundary face between the substrate 1 and the film 3 is low if the thickness is <=50Angstrom .

Title: Interruption control system
Inventor: HARADA EIJI
IPC: G06F13/24
Filed: 1987-11-13
Abstract: PURPOSE:To facilitate the interruption multiplexing process without complicating the program structure by setting the interruptions received from each interruption request device under a maskable state idividually at the outside of a processor and under the control of the processor. CONSTITUTION:It is decided by the state of an FF 4-5 whether the interruption received from an interruption request device 15 having the lowest priority is masked or not among those interruption request devices 13-15. The state of the FF 4-5 is controlled when an order is supplied to an interruption control circuit 4 from a processor 1 via an address bus 11 and a decoder 10. When a masking action is set to the interruption received from the device 15, the due signals are obtained at a mask setting terminal 7 and a chip selection terminal 9 with the order received from the processor 1. These signals reset (mask setting) the FF 4-5 via an AND gate 4-2 and an OR gate 4-3. When the FF 4-5 is released, the due signals are obtained at a mask resetting terminal 8 and the terminal 9 by the order received from the processor 1. Then the FF 4-5 is set via an AND gate 4-1 with a delay.

Title: Substrate treatment apparatus and treatment tank used therein
Inventor: MURAOKA YUSUKE
IPC: H01L21/304
Filed: 1994-11-22
Abstract: PURPOSE: To reduce the inner vol. of a vacuum chamber to a large extent by preventing the re-adhesion of particles to a substrate after the washing of the substrate. CONSTITUTION: When a treatment tank 1 is drained after a substrate 3 is washed with pure water, pure water is discharged from an outer plate 101 while supplied from the bottom part of the treatment tank 1. The treatment tank is partitioned by partition plates 112 and the pure water in the space between them is discharged rapidly as compared with the pure water in the space inside the partition plates 112. As a result, difference in level is generated between the liquid level in the former space and that in the latter space and the pure water of the surface of the latter space flows down to the outside through a through-hole and the liquid level thereof lowers by the overflow of pure water and, therefore, particles floating on the surface of pure water overflow to be discharged and the re-adhesion of particles to the surface of the substrate is prevented.  Since drainage is performed while the substrate is stopped within the treatment tank, it is unnecessary to provide a substrate lifting space in a chamber and the inner vol. of the chamber can be reduced.
