    摘要: A powder feed apparatus and a control method thereof for a powder molding press wherein in feeding powder from a hopper of the powder feed apparatus to a feeder slidably disposed on a die plate of the press proper and charging powder into a die in the die plate the feeder is electronically controlled to a correct position on the die. Powder is fed from a powder feed apparatus into a feeder slidably disposed on a die plate of a press proper and a feeder drive motor is servo-controlled by an output obtained by comparing detection outputs from a position detector for detecting the vertical position of the die plate of the press proper and a position detector for detecting the position of the feeder in its sliding direction. As a result, it is possible to avoid the trouble of changing cams or inserting insert cams every time the shape of the compact being molded changes and it is possible to easily make changes to the movement speed of the feeder in correspondence with changes to the compact.

    摘要: Proposed is a magnetic recording medium consisting of a non-magnetic substrate and a magnetic recording layer formed thereon by the method of sputtering, in which the non-magnetic substrate is a disk of single crystal silicon having a surface of the crystallographic orientation of (100), the surface roughness Rp being 40 nm or smaller. By virtue of the use of the unique material for the substrate, the magnetic recording layer is outstandingly stable as compared with conventional aluminum or glass substrates and the magnetic layer formed thereon by sputtering has a greatly improved coercive force of 1300 oersted or higher.

    摘要: In a photomask blank comprising a light-shielding film and an antireflective film on a transparent substrate, the light-shielding film and the antireflective film are formed of a chromium base material containing oxygen, nitrogen and carbon such that the content of carbon decreases stepwise or continuously from a surface side toward the substrate. The photomask blank can be etched at a controlled rate to produce perpendicular walls. A photomask is manufactured by lithographically patterning the photomask blank. The photomask blank and photomask have uniform film properties and contribute to the microfabrication of semiconductor ICs of greater density and finer feature size.

    摘要: The present invention provides a magnetron sputtering system, which ensures a formation of a desired thin film, using a thick target. In the sputtering process, a portion of the target does not have erosion free portions. The present invention provides a magnetron sputtering system comprising a chamber for sputtering, a target electrode 5 installed inside said chamber, a substrate electrode 6 installed in the chamber opposite to the target electrode, a ring-shaped magnet 2 installed so as to enclose the side surface of the target electrode, and a semi-circular disk shaped magnet installed opposite to the target-mounted surface of the target electrode, wherein the semi-circular disk shaped magnet is rotated in the circumferential direction of the target electrode and is magnetized in the direction perpendicular to the target electrode. This ensures a specific magnetic field component to be generated over the thick planar target surface 3.
