Title: Production of magnetic recording medium
Inventor: NIIMI HIDEAKI
IPC: G11B5/85
Filed: 1987-07-09
Abstract: PURPOSE:To improve magnetic characteristics by forming an underlying layer and magnetic layer by a sputtering method using an insert gas and specifying the concn. of water in the inert gas to be introduced. CONSTITUTION:The underlying layer and the magnetic layer are formed by the sputtering method using the insert gas and the concn. of the water in the inert gas to be introduced is confined to <=10ppm. Namely, water molecules infilter together with the inert gas into a sputtering chamber and form a water molecular film onto the surface of the underlying layer by attraction thereto, it the water molecules remain in a piping system for introduction of the inert gas or intrude as impurities into a gas cylinder. The concn. of the water in the inert gas is, thereupon, decreased to <=10ppm, by which the magnetic layer is sufficiently epitaxially grown on the surface of the underlying layer without receiving the influence of the water molecules even in the sputtering method. The magnetic characteristics are thereby improved.

Title: Spindle servo device
Inventor: TAKAHASHI HIROYUKI
IPC: H02P29/00
Filed: 1990-06-29
Abstract: PURPOSE:To regulate relative gain of both a speed servo system and a phase servo system by selectively connecting a capacitive impedance element in response to the operation mode of each servo system to the output line of a PWM circuit of a motor driver. CONSTITUTION:When only a speed servo system is operated, a transistor Q is turned OFF, and a capacitor C is not connected to the output line of a PWM circuit 11. When a phase servo system is operated in addition to the speed servo system, the transistor Q is turned ON, the capacitor C is connected to the output line of the PWM circuit. Thus, when the phase servo system is operated, a voltage is provided even in a high impedance zone by the connection of the capacitor C. Accordingly, the gain of the phase servo system can be apparently raised. Since the gain can be freely set by the capacity of the capacitor C to be connected, an optimum gain can be set.

IPC: B05C1/02
Filed: 1999-06-18
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a flattening film by which irregularities can be eliminated conveniently and uniformly. SOLUTION: In this method for forming a flattening film, first, a photosensitive resin with a viscosity of 500 to 5000 cPs is applied on a substrate by using a flat rubber roll of 95±5 deg. in hardness, so that the photosensitive resin can be sufficiently applied to a recess even by a small quantity thereof and uniform application. Then, the photosensitive resin is dried, and furthermore, the application and drying steps are repeated by using a rubber roll with grooves until its thickness will reach a predetermined thickness, thereby obtaining easily a flattened insulation layer 80 having the predetermined thickness. As a result, grinding or pressurizing is not needed and the number of production steps is reduced, thereby eliminating the irregularities in the insulation layer 80 conveniently and uniformly.  Furthermore, the quantity of applied photosensitive resin, i.e., the film thickness of the insulation film 80 can be controlled by changing the viscosity of the photosensitive resin and the shape of rubber of the rubber roll with grooves such as groove pitch, groove depth, etc.

Abstract: PURPOSE:To prevent a strong electric field generated locally near interface place between the high-potential region of an SOI field effect transistor and its buried oxide film, by so forming its high-potential side electrode contacted with the region to be changed into the high-potential side of its drain diffusion region that this electrode is extended from the surface of its semiconductor active region to the position of the depth of its insulation substrate. CONSTITUTION:A drain electrode 15 contacted with a drain diffusion region 7 to be changed into a high-potential side is so formed that this electrode is extended from the surface of a silicon active layer 4 to the position of the depth of this electrode to contact an insulation substrate 3 (a buried oxide film 2). By such configuration, the drain potential of an SOI field effect transistor is given from the drain electrode 15 extended from the surface of the silicon active layer 4 to the insulation substrate 3, when the potential of the drain diffusion region 7 is made high and the potentials of a source diffusion region 6 and a substrate electrode 12 are made low respectively. Therefore, the distortion of the potential distribution relative to the drain electrode 15 is corrected, and as a result, the strong electric field concentrated on the interface place between the drain diffusion region 7 and the buried oxide film 2 which is present near the silicon active layer 4 can be relaxed.
