Abstract: PURPOSE:To increase adhesive strength between a base material and a coating and to improve peeling resistance by forming a coating at a temp. lower than the optimum formation temps. of various coatings until a primary layer reaches a specific thickness at the time of forming coatings on a base material composed of sintered hard alloy. CONSTITUTION:A single or plural layers consisting of one or more kinds among the carbides, nitrides, carbonitrides, and oxycarbonitrides of the group IVa, Va, and VIa metals and Al oxide are formed by a chemical vapor growth method on the surface of a base material composed of a sintered hard alloy consisting of one or more kinds among the carbides, nitrides, and carbonitrides of the group IVa, Va, and VIa metals and iron group metal. Al this time, film formation is performed at a temp. lower than the optimum formation temp. of a primary layer situated nearest to the base material by 100-500 deg.C until the thickness of the primary layer reaches 1mum. By this method, the diffusion of carbon from the base material can be inhibited and the formation of brittle layer can be prevented, by which a film having high adhesive strength to the base material can be formed. Further, crystalline grains in the film can be refined, and a coated sintered hard alloy tool improved in wear resistance can be obtained.

Abstract: PURPOSE:To form a wiring layer, which has a good step coverage and has a low resistance, by a simple manufacturing method in a short time. CONSTITUTION:A germanium layer 11 (a film thickness of 50nm) is first formed on a barrier metal layer (a titanium layer 26 and a titanium nitride layer 27).

At this time, the layer 11 reacts with the layer 12 and an aluminium alloy layer 13, which shows a high fluidity, is formed. As a result, a sufficient filling is made also in the interiors of fine contact holes 25. Subsequently, a thick aluminium alloy layer 14 (1% of Al, 0.5% of Si and 98.5% of Cu and a film thickness of 500nm) is rapidly formed (a film-forming rate of 1mum/min or thereabouts) on the layer 13 by a normal sputtering method at the substrate temperature dropped to 150 deg.C or thereabouts.

Title: Memory back-up device
Inventor: ITO YOSHIAKI
IPC: G06F1/26
Filed: 1988-11-09
Abstract: PURPOSE:To eliminate the need for exchanging a battery with a power source being turned on and to secure safety by backing up a volatile memory by means of an electric double layer capacitor when the power source is turned off. CONSTITUTION:When the power source 14 is turned on, the electric double layer capacitor 18 is charged by the power source 14.

By viewing through the reflection with the eyeglass face 1 and the object glass face 2, with the angle θ4 set from 10 deg. to 40 deg., the optical path of the line of sight is refracted from 20 deg. to 80 deg.; therefore, with the line of sight faced to the eyeglass face 1, an object in the direction of an elevation angle or depression angle can be viewed as an erected image.  The eyeglass face 1 is desirably positioned away from the joint line 3 so that the ratio of the vertical width M of the eyeglass face 1 to that W of the window part 5 may be from (1:0.5) to (1:3). The eyeglass face 1 and the object face 2 can be freely rotated with the joint line 3 as an axis.

Title: Production of methacrylamide crystals
Inventor: KAWAKAMI KIYOSHI
IPC: C07C67/00
Filed: 1987-11-11
Abstract: PURPOSE:To obtain methacrylamide crystals which is used in coating, adhesive, as a photosetting compound, fiber modifier or resin processor, by crystallizing out the crystals from the methacrylamide aqueous solution formed by using a catalyst from a living body without excessive consumption of energy. CONSTITUTION:The hydration reaction of methacrylonitrile is carried out using a living body catalyst such as Rhodococcus AK32 strain, to give a methacrylamide aqueous solution. Then, the reaction product is combined with a solvent which is capable of cooling other substances such as n-pentane to separate the methacrylamide crystals from the slurry. The mother liquor is recycled to the hydration reaction, while the solvent phase is given cooling ability again. The cooling heat energy from the aqueous methacrylamide is utilized to remove the heat of the hydration reaction. Further, the selection of the solvent of low melting point enables a large temperature difference from the cooling medium whereby the heat transfer area can be minimized, resulting in the size reduction of the facility.

Abstract: PROBLEM TO BE SOLVED: To reduce the off leakage current of individual memory cell in a memory chip. SOLUTION: At the stand-by time of the memory chip, a grounding source line 24 of a flip-flop constituting the memory cell 21 is made a floating state intermittently. Thus, an NMOS transistor QN5 is interposed between the grounding source line 24 and a power source VSS, and its gate is controlled by an activation signal ACT.
