Title: Reinforcement welding performance method for concrete column
Inventor: MIYAGAKI TADAHIKO
IPC: B23K9/173
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To perform reinforcement welding performance for a concrete column at a low cost with high efficiency by using longitudinally divided members as an exterior steel plate, and fitting and uniting a thin backing material. SOLUTION: Backing 4 is temporarily welded to one reverse surface of a steel plate 2 on the back side of the steel plate 2, and the other steel plate 2 is applied. On the top side of the steel plate 2, slide copper backing is applied and a groove to be welded is formed; and the slide copper backing and a welding torch are both elevated on a travel carriage as the welding is advanced. The welding is advanced while a bead is formed by generating an arc between a wire and molten metal and melting the groove part of the steel plate 2 and the wire. The weld zone is shielded by being supplied with gaseous CO2 from a gas supply hole provided on the slide copper backing, which is welded while cooled with water fed and discharged through a cooling water pipe hole.

Title: Delivery pipe temperature controller of compressor
Inventor: TANAKA OSAMU
IPC: F25B1/00
Filed: 1989-12-14
Abstract: PURPOSE:To prevent a compressor from unnecessarily being reduced in the capacity and from hunting by a method wherein the sampling interval is shortened depending not only upon the absolute value of the delivery pipe temperature of the compressor but also upon the judgment of trend of rise or fall in the temperature. CONSTITUTION:The delivery pipe temperature TD of a compressor 1 is detected by a delivery pipe temperature detector Th7, and compared with a temperature previously detected to decide the trend of rise or fall in the delivery pipe temperature TD. When it is judged that the delivery pipe temperature TD tends to rise, the operating capacity of the compressor 1 is reduced by a controller 61 at regular time intervals. On the other hand, it is judged that it is other than rising trend, the operating capacity of the compressor 1 is maintained and controlled according to the absolute value of the delivery pipe temperature TD and the trend of rise or fall in the temperature. Thereby, the compressor 1 is prevented from unnecessarily being reduced in the capacity and from hunting, causing an extension of continuous operating range.

IPC: H01L21/31
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce a standard deviation in a batch and a wafer on a thin oxide film in the forming method of the thin oxide film on the semiconductor wafer. SOLUTION: At the time of inserting plural semiconductor wafers into a normal pressure vertical oxide furnace, air between the semiconductor wafers is speedily substituted.
