Title: Production of niobium oxide
Inventor: INOUE ETSUO
IPC: C01G33/00
Filed: 1985-12-28
Abstract: PURPOSE:To separate and recover Ta and also to collect Nb2O5 in excellent yield by treating ore wherein Nb and Ta coexist by the chemical and physical methods of the plural stages. CONSTITUTION:Ore such as columbite wherein Nb and Ta coexist is treated by hydrofluoric acid and sulfuric acid to dissolve it and the supernatant liquid is filtered and separated from an undissolved residue and Nb and Ta are extracted by solvent from the obtained filtrate. After extracting Nb into an aq. phase from this solvent extract and separating it from Ta, purity of Nb is increased by removing the impurities contained in the aq. phase. After vacuum-drying this aq. soln. contg. high-purity Nb and solidifying it, Nb2O5 is obtained by calcining and oxidizing it in a furnace wherein the inside wall is lined with Nb2O5. Purity of Ta is increased by removing the impurities from an oil phase obtained in the separating process of Nb and the oil phase is neutralized by NH3 to transfer Ta into an aq. phase and after Ta is precipitated, it is dehydrated and calcined. Hydrofluoric acid and sulfuric acid discharged in this producing process is cooled, recovered and reutilized in the treatment of ore and also NH3 and NH4F similarly discharged are cooled, recovered and reutilized for neutralization of the Ta-contg. oil phase.

Conductive protrusions 13 are formed at the exposed parts not covered with the insulating films of the electrodes 12. In this case, when the electrodes 12 are covered with the layers 15, they are so covered that the electrodes 12 are exposed in a zigzag manner near the ends of the electrodes. Accordingly, the protrusions 13 are formed in a zigzag manner. Thus, a desirable contact state is held to a print recording medium even by a smaller pressure contact to further contribute to the increase in the lifetime of a print head.

Title: Dry plating method for steel material
Inventor: OWADA SATORU
IPC: C23C26/00
Filed: 1986-12-18
Abstract: PURPOSE:To improve the rust and corrosion preventiveness of a steel material by a dry plating method by projecting shots of a Zn alloy or the like on the surface of the steel material and melting the shots by heating in a specified atmosphere. CONSTITUTION:Zn or Zn alloy shots or shots each having a Zn or Zn alloy layer on the surface is projected on the surface of a steel material. The surface of the steel material is then heated to 420-800 deg.C in a nonoxidizing or weakly reducing atmosphere or in vacuum to melt the shots and to form a plated layer. Thus, the blasted surface can be sealed without oxidizing, so the rust and corrosion preventiveness of the steel material can be improved without exerting any influence on the steel material. This method is useful to temporarily prevent the rust of steel stock or to pretreat steel stock before painting.

Title: Stainless steel hot water storage tank
Inventor: FUJISHIMA MICHIYUKI
IPC: B65D90/08
Filed: 1989-11-17
Abstract: PURPOSE:To shorten manufacturing time and to eliminate leakage after use by providing a rib formed on a circumference near the skirt edge of an upper cover, and a rib formed on a circumference near the skirt edge of a lower cover. CONSTITUTION:An upper cove is manufactured by drawing and edging a stainless steel plate to form a skirt edge, and then ribbing by a press to form a rib A. In this case, since a stress relaxation at the time of drawing occurs before the rib A is formed, the skirt edge is formed in a zigzag manner as a conventional example, but the zigzag is then corrected on the circumference of the skirt edge by the ribbing, and straightly finished. A lower cover is similarly ribbed to form a rib B. When both the covers are adhered, the skirt edge 2a is smoothly superposed on the slope of the rib B, and no gap is generated at the superposed part. Thus, both the covers can be welded smoothly without mistake, welding time is shortened, and a leakage malfunction after use is prevented.

Title: Cache memory control system for information processor
Inventor: HIRANO MASANORI
IPC: G06F12/12
Filed: 1987-11-28
Abstract: PURPOSE:To make it unnecessary to include a storage instruction information forming part in an external cache memory by allowing a control part in the external cache memory to receive storage instruction information outputted from an instruction execution part in a processor. CONSTITUTION:When the instruction execution part in the processor 1 requests the 2nd external information positioned on a specific address, the control part 5B in the external cache memory CB receives the storage instruction information outputted from the instruction execution part of the processor 1 similarly to the reception of the information by a control part 5A of an internal cache memory CA in the processor 1. Thus, an information storage part 3B in the external cache memory CB is controlled so that the 2nd external information from an external information source S is outputted to the instruction execution part in the processor 1 without being stored in the storage part 3B in the cache memory CB. Consequently, it is unnecessary to form the storage instruction information forming part in the external cache memory CB.

Title: Semiconductor pressure sensor
Inventor: HAYASHI TADAHIRO
IPC: G01L9/04
Filed: 1986-12-19
Abstract: PURPOSE:To reduce a scattering in a characteristic of pressure sensitivity, by forming a pressure receiving diaphragm so that it becomes gradually thicker as it goes to the center from the periphery and forming its central part in fixed thickness. CONSTITUTION:Circular step parts 5b and 5c are formed on a rear of a pressure receiving diaphragm 5 so as to be thicker gradually steppedly toward a central part of the diaphragm from the thin part 5a on the periphery. A ratio of thickness h2 of the circular step part 5c to thickness h1 of the peripheral thin part 5a depends on a diameter of the pressure receiving diaphragm 5, and is selected to be 1.2 or so. Piezo-resistance parts 3 and 4 are formed on a front side of the thin part 5a. When pressure P is applied, the thick part of the circular step part 5c functions as a rigid body, and distortion occurs mainly on the side of the peripheral thin part 5a. According to the amount of this distortion, a resistance value of the piezo-resistance part 3 changes in the plus direction, and that of the piezo-resistance part 4 changes in the minus direction. Since the thickness ratio is selected to be a prescribed value of 1.2 or so, non-linearity of the pressure to the resistance changing value becomes approximately zero.
