IPC: H01F1/057
Filed: 1990-04-06
Abstract: PURPOSE:To manufacture a warm-worked magnet which is free from cracks after processing and is excellent in characteristics by pre-molding a dense body for the purpose of plastic processing in a uniform strain distribution and in a near net shape in a warm plasticity processing process. CONSTITUTION:In a warm-worked magnet mainly containing transition metal T, to which magnetic anisotropy is given by R-T-B rapid cool processing obtained by rapidly solidifying melted R-T-B alloy containing rare earth elements R and B which contain yttrium, a final plasticity-processed body has a uniform strain distribution and a near net. In this densifying processing, plasticity processing is done after a dense body has been molded in such a manner wherein linear parts or curved parts except corners contained in surfaces in contact with upper and lower dice in a dense body are recessed toward a surface which is 15% or lower for example with respect to a similar figure of a finally plastically processed product shape in length of the line or the curve while other sides of the dense body are in parallel with a compression direction toward the center of the dense body or recessed by 15% or lower with respect to height of the sides.

Title: Wafer aligning system
Inventor: MAAKU ESU UONTA
IPC: G03F9/00
Filed: 1988-04-14
Abstract: PURPOSE: To enhance the reproducibility of alignment by using a cross target mark as a means of aligning a reticle image projected on a semiconductor wafer by the step repetitive method with a target at a scribe region of the wafer. CONSTITUTION: A light cone 12, originating from an image point on a reticle 14, is reflected down to form an image point on a wafer 16. A wafer target 24 enters a projected image of a reticle key 26, to scatter light in every direction from the edge of the target 24. Part of the light goes up a dark center cone, to form an image on a cross mask 15 again. A photomultiplier 17 senses the light intensity thereof to return a signal voltage during scanning of the wafer target 24 through the reticle key image. The signal is amplified and displayed on a target-aligning monitor. The reverse scan provides a second position sample for cancelling the phase error. The mean value of the two samples provides the target position, thereby obtaining a reproducibility of ±0.14 microns.

Filed: 1991-03-29
Abstract: PURPOSE:To decrease the discharging amounts of moisture and contaminated material discharged from metallic materials constituting a particulate meter by attaching oxide passive-state films on the wall surfaces of the flow paths of an introducing part and a discharging part. CONSTITUTION:An introducing part 2 and a discharging part 4 made of metal material, e.g. SUS material, are heated to the vicinity of a melting point. The, iron and chromium in the SUS material are deposited and made to react with oxygen. Oxide passive-state films 11 and 12 comprising the hydroxides of the iron and the chromium are formed and attached to the side walls of flow paths 2A and 4A of the introducing part 2 and the discharging part 4. Thus, moisture and contaminated components present in the thick parts of the introducing part 2 and the discharging part 4 become hard to be transmitted through the films 11 and 12. Therefore, when a fluid to be inspected FL passes through the flow paths 2A and 4A, the discharging amount of the moisture and the contaminated components discharged into the fluid to be inspected FL can be decreased.

Title: Formation of pattern
Inventor: DEGUCHI KIMIKICHI
IPC: H01L21/027
Filed: 1984-05-11
Abstract: PURPOSE:To enable to form a favorable pattern removed with the influence of a diffraction figure at formation of the pattern by method wherein a middle layer consisting of a material having the photo ionizing sectional area larger than the material of a substrate is inserted between the substrate and an organic resist layer. CONSTITUTION:A middle layer 11 is formed on a substrate 1, and after then, an organic resist layer 2 is applied thereon. Then synchrotron radiation 6 is projected through an X-ray mask 5 having an X-ray absorber 3 on a membrane 4. At this time, photo-electrons 12 are generated from the layer 11 to expose the resist part in the neighborhood of an interface. As a result, the part made to be insufficient with exposure according to a diffraction figure is also exposed. Moreover, exposure according to a radiant beam 6 can be reduced by the amount of exposure according to the photo-electrons 12. Therefore, according to a decline of brightness of the bright part of the diffraction figure, a recess part is not formed even when a development process is performed. The larger the generating quantities of photo-electrons from the layer 11 become, the more the effect mentioned above is improved, and accordingly a material having the photo ionizing sectional area larger than the material of the substrate is suitable as the layer 11.
