Title: Production of unidirectionally solidified wire
Inventor: TAKAYAMA TERUYUKI
IPC: C22B9/16
Filed: 1988-02-17
Abstract: PURPOSE:To stably and uniformly produce the title high-quality unidirectionally solidified wire by transferring a high-frequency induction heating coil to melt the specified zone of a vertically held wire, and forcedly cooling the melting and solidifying zone. CONSTITUTION:A wire 11 is straightened by a straightening machine 16 to obtain a straight wire 12. The wire 12 is transferred to the lower part by pinch rolls 17 and 20, and stopped at a specified position. The high-frequency induction heating coil 18 and a spray nozzle 19 are then slowly lifted from the lower-end position A to the upper-end position B. The zone 13 of the wire 12 enclosed with the coil 18 is induction-heated, and melted. The molten zone is passed through the coil, cooled by heat transmission, and solidified. The solidified wire 14 is immediately and forcedly cooled by the cooling water injected from the nozzle 19. As a result, a unidirectionally solidified structure extending in the axial direction is formed in the wire 14, and a unidirectionally solidified wire can be efficiently obtained without causing the blowoff of molten metal, etc.

Filed: 1982-03-04
Abstract: PURPOSE:To form a U-shaped inner tube with no bending process by a method wherein one linear inner tube, whose one end airtightly contains an electrode and the other end is blocked, and another linear inner tube whose one end is open while the other end is blocked, are deposited together at their blocked ends and put in continuity each other. CONSTITUTION:Electrodes 31 and 32 are sealed to a substrate 21 of an outer tube 1. One linear inner tube 41 whose one end airtightly contains the electrode 31 and the other end is blocked, while its inner wall is applied with a phosphor layer 8, and another linear inner tube 42 whose one end 44 is open and the other end is blocked, are both locally softened in their blocked end sides to make a hole by feeding in air for the purpose of mutual continuity, thus a U-shaped  inner tube 4 is formed. Further, a fixed quantity of mercury and rare gas is  made to exist in the outer tube 1 which is to be formed into a low pressure mercury-vapor discharge lamp having a bent discharge route. Accordingly the U- shaped tube 3 can be formed with no need of bending process thus to simplify  manufacture.

Abstract: PROBLEM TO BE SOLVED: To relax a stress and realize recovery from a residual defect, by performing furnace heat treatment after formation of a sidewall insulating film, then doping an Si substrate with arsenic to cause the Si substrate to be amorphous, and forming a Ti film thereon to form a silicide. SOLUTION: Gate electrodes 15, 35 are formed via gate insulating films 14, 34 on a silicon substrate 11. Sidewall insulating films 18, 38 are formed on the substrate 11 on the lateral sides of the gate electrodes. Then, ion implantation for oxidizing the silicon surface to form source and drain regions 19, 20, 39, 40 is performed, and furnace heat treatment is performed. After the oxide film on the surface of the silicon substrate 11 is removed, the silicon substrate 11 is doped with arsenic, thus causing the surface side of the silicon substrate 11 to be amorphous. Then, a titanium (Ti) film 51 as a metal film for forming a silicide film 52 is formed. Thus, since furnace heat treatment is performed, the stress generated on the silicon substrate at the end of the sidewall insulating film may be relaxed and recovery from a crystal defect is enabled.

Title: Heat-generating resistor type apparatus for measuring flow rate of air
Inventor: WATANABE IZUMI
IPC: G01F1/692
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To improve the responsivety, measuring accuracy and mechanical strength, by setting a non-heat-generating band of a width corresponding to the thickness of an electrically insulating substrate between a pair of heat- generating resistor element arranged on the substrate parallel to a flow direction. SOLUTION: A non-heat-generating band of a width 5 equal to or twice a thickness 6 of a ceramic substrate 4 of alumina or the like is formed between an upstream heat-generating resistor element 2 and a downstream heat- generating resistor element 3 arranged on the substrate 4 close to the upstream and downstream of a flow to a flowing direction of a fluid. When the ratio of the band width 5 to the thickness 6 is not larger than 1, output noises are large. On the contrary, as the width 5 becomes larger, responsivity is worsened. Therefore, the width 5 of the non-heat generating band is set in a ratio range of 1-2 where noises are not large and the responsivity is not greatly changed. In this manner, a substrate structure with superior mechanical strength, measuring accuracy and responsivity is obtained.
