Title: Metallic protrusion for replication bump
Inventor: HATADA KENZO
IPC: H01L21/60
Filed: 1987-03-27
Abstract: PURPOSE:To peel a metallic protrusion easily from a substrate, and to improve replication and junction rates by composing the metallic protrusion on the substrate of a plurality of layers consisting of the same material and having different hardness. CONSTITUTION:A layer having different hardness is formed into a metallic protrusion in order to peel a metallic film 3 and the plated metallic protrusion, thus generating internal stress, then lowering the adhesion of the interface between a substrate 2 and the metallic protrusion. That is, since the metallic protrusion is shaped from such layers having a plurality of hardness, layers having stress proportional to hardness by the difference of hardness appear in the metallic protrusion. The layers having stress are generated, thus weakening adhesion between the substrate and the metallic protrusion, then easily releasing the metallic protrusion from the substrate. Accordingly, replication and junction properties to a film lead of the metallic protrusion selectively formed onto the metallic film 3 on the substrate 2 can be improved.

Title: Second information embeding method to image information and its decoding method
Inventor: MATSUURA HIROSHI
IPC: H04N1/44
Filed: 1991-04-08
Abstract: PURPOSE:To increase an embed enable information quantity and to decrease distortion due to the embeded information. CONSTITUTION:In the case of the length of an embed object run RL(a0a1) being equal to a setting parameter L+c, the length of a just succeeding run RL(a1a2) being L+d and c<=d, a picture element a1 is inverted for the embeding to increase the length RL(a0a1). In the case of c>d conversely, a just preceding picture element to the picture element a1 is inverted for the embeding to decrease the RL(a0a1). In both the cases, no embeding is implemented to a run whose length is below L. Whether the information is to be embeded similarly to the case with a conventional method or is not modified depends on odd or even number of the length of a run of embed object and bits '1', '0' of embed information.

Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To improve the production capacity without making an equipment large in scale by cooling molten pig iron in a mold, making a molded pig iron having the solidified shell on the surface layer part, separating the molded pig iron from the mold, water-cooling the whole surface of the molded pig iron and solidifying it completely. SOLUTION: The molten pig iron is poured into the mold 1 on a mold conveyor 18. Mist is atomized from air-water mist spray nozzle 16 to cool the molten pig iron. When the solidified shell of the molten pig iron grows such degree as not to be broken by releasing and dropping, this pig iron is separated from the mold 1 as the molded pig iron 5. The molded pig iron 3 is laid on a mesh belt-made mesh conveyor 13 and cooled by spraying the water from the upper and the lower sides with a water spraying equipment 3. Since the molded pig iron 5 is cooled from its whole surface, the cooling speed is accelerated. Since the cooling on the mold conveyor 18 is executed untill the solidified shell is formed, the length of mold conveyor 18 is drastically shortened in comparison with the conventional pig iron casting machine.

Abstract: PURPOSE:To provide a semi-insulation compound semiconductor epitaxial layer exhibiting a high resistivity by growing an undoped compound semiconductor epitaxial layer on the surface of a single-element semiconductor substrate and then performing heat treatment of the substrate for semi-insulating the epitaxial layer. CONSTITUTION:A substrate which is subjected to epitaxial growth is taken out, is loaded into a crystal ampoule along wit arsenic, and then is vacuum- sealed. In this case, the amount of arsenic is determined so that a vapor pressure preventing arsenic from volatilizing from the substrate surface at a heat treatment temperature can be obtained. Then, after the crystal ampoule is loaded into a heating furnace and then is subjected to heat treatment for three hours at 950 deg.C, it is cooled. After heat treatment, the surface of the wafer is eliminated by approximately 10mum by lapping and then resistivity is measured by the Van der Pauw method to confirm that GaAs epitaxial layer with a resistivity of 1X19<7>OMEGA.cm or higher is formed. Hence, the epitaxial layer can be semiinsulated.

Title: Striking method
Inventor: NISHIYAMA YOSHIROU
IPC: C25D5/18
Filed: 1983-04-28
Abstract: PURPOSE:To improve the adhesive strength of a film formed by striking on a material with inferior suitability to electrodeposition by forming a film at a high current density in a short time in the early stage of striking and by carrying out striking at a low current density for a prescribed time. CONSTITUTION:When a metal with inferior suitability to electrodeposition such as Rh is subjected to Au striking, Au striking is carried out on Rh at >=3A/ dm<2> high current density for a short time, and the striking is continued at about 0.2A/dm<2> low current density. The resulting Au layer is electroplated with Au by a conventional method to form an Au layer. Since the under Au layer with superior adhesive strength is formed even on Rh with inferior suitability to electrodeposition, the upper Au layer is not stripped from Rh.
