Title: Welding method for tube panel
Inventor: NAKAJIMA KUNIHIRO
IPC: B23K9/00
Filed: 1988-02-12
Abstract: PURPOSE:To prevent the occurrence of welding distortion and to eliminate straightening work by welding simultaneously four corner parts of a member to be welded of a tube panel by two downward TIG torches on the surface side and two upward TIG torches on the rear side. CONSTITUTION:The two torches 11 and 13, and the two torches 12 and 14 are arranged respectively with respect to a surface side weld zone and a rear side weld zone. The TIG torches are used wholly for the four torches. In TIG welding, the heat input is relatively low and accordingly, the penetration is little and a pool is also small. Consequently, even with the overhead position, molten steel is prevented from drooping and satisfactory fillet welding can be performed. The four torches are inclined at a prescribed angle on the horizontal surface and arranged at prescribed intervals in the welding direction from physical restriction. By this method, the occurrence of the welding distortion is prevented and inversion of a work is not necessary and a manufacturing stage can be simplified.

Filed: 1982-03-01
Abstract: PURPOSE:To improve adhesion power and to decrease electrical resistance, by using the material prepd. by dispersing conductive powders in a polyester resin or polyurethane resin as an intermediate layer. CONSTITUTION:A nonmagnetic layer is formed by coating a coating soln. prepd. by mixing and dispersing the carbon black in, for example, fine conductive powder with and into a polyester resin diluted with an org. solvent, such as cyclohexanone, on a base surface by a gravure coating or other method and drying the same, for which the 1-10% soln. is preferably used. The mixing ratio of the resin and the fine conductive powders cannot be limited because the specific weight of the fine conductive powder differs considerably respectively; a recommended mixing ratio is >=50pts.wt. the resin based on 100pts.wt. the fine powder. If the magnetic layer is formed on the coating film formed in the above- mentioned way, the magnetic recording medium having good balance in both electrical resistance and adhesion is obtained. The magnetic coating of commonly used components may be used for the magnetic coating for forming the magnetic layer.

Title: Buried pipe detecting device
Inventor: OHASHI SEIJIRO
IPC: G01V3/02
Filed: 1993-01-27
Abstract: PURPOSE:To surely detect the approach of a bucket to a buried pipe by feeding a signal current to the buried pipe, and mounting a signal detection means on or near the excavating claw of the bucket. CONSTITUTION:When a signal feed means 2 is installed on a ground position different from the excavating site of an excavator and near a position immediately above an electrically conductive buried pipe 1 and is actuated, a signal current I flows through the pipe 1 that serves as a transmission line, producing a cylindrical magnetic field M along the pipe 1. As a bucket 4 approaches the pipe 1, a signal detecting portion 6 (buried at the bottom of one end of the excavating claw), which always passes a position closest to the pipe 1 during excavating, instantaneously detects the magnetic field M. A signal outputted from the portion 6 is inputted to an output portion 8 and is then amplified, filtered, detected and compared with a reference signal by a detection level comparison circuit. When the level of a signal outputted from a detection circuit exceeds that of the reference signal the comparison circuit outputs a detection signal. Thereby an alarm means 9 is actuated; also, an interrupting device for the drive power source of the excavator is actuated to stop driving the excavator.
