IPC: H01L23/52
Filed: 1990-01-22
Abstract: PURPOSE:To prevent the short circuit between a selectively growing Cu layer and an upper layer wiring and to facilitate the flattening of an upper insulating film by forming the selective growing Cu layer which is formed in the recess part of the insulating layer so that the thickness of the Cu layer is thicker than the thickness of the insulating layer, and arranging the thickness of the selectively growing Cu layer and the thickness of the insulating layer at the same value. CONSTITUTION:The manufacturing method of a semiconductor device has a step for forming a selectively growing Cu layer 13 in recess part 12 of an insulating layer 11 having the recess part 12 wherein a layer 14 that is to become a core of the selective growth is formed at the bottom part. In this manufacturing method, the thickness of the selectively growing Cu layer 13 is formed so that the thickness is thicker than the thickness of the insulating layer 11. The thickness of the selectively growing Cu layer is made to be the same thickness as that of the insulating layer 11. For example, the aluminum layer 14 that is to become the core or the selective growth of Cu is formed only at the bottom part of the pattern groove 12. The selectively growing Cu layer 13 is formed in the pattern groove 12. The selective growth is performed by making the halogenized material formed of Cu and Cl, I or Br react with H2. Then an overgrowth part 13a is removed. The surface of the SiO2 film 11 and the surface of the selectively growing Cu layer 13 are formed on the same plane. Thereafter, an SiO2 film 15 which is an upper insulating film is formed.

Title: Dried urokinase preparation
Inventor: MORIMOTO KAZUO
IPC: A61K38/16
Filed: 1983-01-28
Abstract: PURPOSE:To provide the titled drug preparation effective for the remedy of thrombotic diseases, etc. by using dried urokinase as a main component, and compounding the component with a stabilizer composed of an inorganic salt and/ or an organic acid salt and albumin. CONSTITUTION:The objective dried urokinase preparation is obtained by using dried urokinase as a main component, and compounding a stabilizer containing 30-50mg of albumin and 10-20mg of an inorganic salt and/or organic acid salt per 100,000-30,000 IU of urokinase. The combined use of the components results in the synergistic stabilization of the dried urokinase. Since the stabilizer is effective also for the prevention of the decomposition of urokinase by freeze-drying, it is preferable to add the stabilizer prior to the freeze-drying of urokinase. The albumin is preferably those derived from human, and its purity is preferably >=80% determined by electrophoresis.

Title: Threaded anchor
Inventor: WAKAI TAKAO
IPC: F16B37/04
Filed: 1998-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a threaded anchor with which a surface is smoothly finished after charging, strong fastening force is obtained, and co-rotation is not generated at the detaching time of an attaching screw. SOLUTION: An anchor 1 is composed of a head 2, an edge 5, and a hollow shaft 4 therebetween. On an outer periphery of the hollow shaft 4, a male screw thread 3 whose diameter is increased toward the head 2 is formed. A portion sandwiched by cutouts 11 on the peripheral wall of the hollow shaft 4 serves as a bendable piece 12 which is pushed to project outward by an attaching screw 6 screwed into the hollow shaft 4. The semi-cylindrical edge 5 has a cutting edge 13. Projections 14, 15 are formed on inner surfaces of the edge 5 and the hollow shaft 4 for inclining the attaching screw. A lower hole is formed by cutting a board by means of the edge 5 of the anchor 1. The hollow shaft 4 is inserted into the lower hole through the male screw thread 3. The anchor 1 is fixed to the board. The attaching screw penetrating equipment is screwed into the anchor 1. The attaching screw is thus inclined to the anchor 1 while the bendable piece 12 is projected outward. Turning of the anchor 1 is thus locked. The equipment can be fixed without generating co-rotation.

On the other hand, special steel dust, sludge, etc. are mixed with a carbonaceous reducing agent (coke powder, etc.), cast iron powder, chlorinating agent (CaCl2, etc.) and the mixture is briquetted 5 by a briquetting machine 8. The briquettes are dried and preheated by a heater 7 and are prepd. into a feeder 6. The briquettes 5 are dropped from the feeder 6 simultaneously with falling of the molten slag 4 into the pan 3 and both are thoroughly mixed to accelerate a chlorination reduction reaction. The Ni and Fe in the briquettes 5 are thus made into an Fe-Ni alloy. The molten slag 9 which is thoroughly completed of the treatment is cooled to solidify and is fed to a screening stage 10 where the slag is disintegrated and screened. The reduced metallic particles consisting essentially of Ni are recovered.
