Abstract: PURPOSE:To accurately align the pass line of rolling rolls and the guide line of the guide unit by interposing a center aligning device which makes use of screw grooves between the body and leg part of the guide unit and operating this device from the outside of the machine. CONSTITUTION:If a turning tool is applied to the tool applying end of a drive shaft 61 and the drive shaft is rotated in the required direction when the caliber groove of rolling rolls and the guide line of the roller guide unit causes a deviation, then a drive pinion 63 turns at a fixed angle and according to this, a driven gear 72 is rotated at a fixed angle on a pushing spindle 71. The gear 72 is undisplaceable in the axial direction and the sopindle 71 is prevented from rotating and therefore the spindle 71 is moved in the reguired direction by the relative turning of an internal screw hole 73 and an external screw part 74, by which a push pin 76 is pushed and a skirt plate 3, hence the guide unit integral with this are moved in the same direction. This movement is accomplished by the slide spindle 5 sliding in close fitting with, an insertion hole 44 by maintaining the parallelism with the pass line.

Abstract: PURPOSE:To realize a manufacturing process simple and easy to make a fine processing, through which a superconductive circuit whose circuit property is excellent in reproductivity can be obtained by a method wherein a superconductive thin film is made to vary locally in a resistance value by irradiating an ion beam onto it formed on a substrate. CONSTITUTION:A superconductive thin film 2 is formed on a substrate 1, and an electron beam or an ion beam is irradiated thereon so as to make the thin film 2 vary locally in a resistance value. For instance, the superconductive thin film 2 formed of YBa2Cu3O7-delta(delta=0.0-0.5) is evaporated on the substrate 1 formed of MgO single crystal through a RF magnetron sputtering method, and the evaporated film is subjected to a heat treatment at a temperature of 800-900 deg.C in the atmosphere for one hour to form the film 2. Next, Ni element formed into an ion beam 4 of 15keV is injected into a specified part of the YBa2Cu3O7-delta superconductive thin film 2. As the part 3 where Ni ions are injected loses a superconductive property, if a ion beam 4 is irradiated onto the surface of the superconductive thin film 2 in line, a superconductive circuit as shown in a figure can be manufactured.

Title: Production of goethite particle powder assuming spindle form
Inventor: KUROKAWA HARUMI
IPC: C01G49/02
Filed: 1992-01-13
Abstract: PURPOSE:To provide the subject method for producing goethite particle powder in which the particle powder assuming a spindle form having a uniform particle size and a large axial ratio (major axis diameter/minor axis diameter) without mixing dendritic particles therein is industrially obtained. CONSTITUTION:An aqueous solution of an alkali carbonate or a mixed aqueous solution of the alkali carbonate with an alkali hydroxide is made to react with an aqueous solution of a ferrous salt to provide a suspension of pH8-10 containing FeCO3-or Fe-containing precipitates. The resultant suspension is then aged in a reducing atmosphere and an oxygen-containing gas is then aerated into the suspension to carry out oxidizing reaction. Thereby, the objective goethite particles assuming a spindle form are produced. In this process, the previous presence of a reducing agent in the solution before aging the liquid containing the FeCO3-or Fe-containing precipitates to afford the goethite particle powder can cause the production of goethite particles having a uniform particle size and a large axial ratio and assuming the spindle form without mixing dendritic particles therein.

Title: Semiconductor device
Inventor: MITSUI SHINJI
IPC: H01L23/52
Filed: 1984-02-10
Abstract: PURPOSE:To obtain the titled device excellent in moisture resistance by a method wherein an Al layer is formed on the final protection film of a semiconductor element. CONSTITUTION:An Si nitride film 1 is used as the final protection film after passage through a normal wafer process. The formation of an Al film 2 on the final protection film can be carried out either by sputter used in formation of the inner wiring or by vapor deposition. However, since the neighborhood of a bonding pad 4 has the possibility of short with said Al film 2 at the time of wire bonding, this film 2 should be formed at a suitable distance from an edge 5 of a bonding pad window. Now even if water infiltrates into the resin section, the water reacts with the Al on the surface protection film earlier than with the inner Al wiring in the element, and is consumed by forming a water oxide film of Al2O3.3H2O or Al(OH)3; therefore, it is difficult to reach the inner Al wiring. Further, the water that has dissolved the Al of a sacrifice electrode during the course of infiltration contains aluminum ions and its pH varies close to neutral, resulting in the difficulty of corroding the inner Al wiring.
