Title: Covered arc welding electrode for galvanized steel
Inventor: YAMANE KUNIHIDE
IPC: B23K35/365
Filed: 1998-01-16
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of a defect of pit, blow hole or the like, in welding a galvanized steel plate or the like, by specifying weight % to the whole coating agent of a carbon amt. contained in a coating agent. SOLUTION: In welding a galvanized steel plate, since a pit and a blow hole are easy to be generated, air entrainment due to bumping of zinc at a welding time is promoted, since the zinc penetrated into fused metal is hardly fused into iron and has a low boiling point, the zinc is in a vapor state in a process solidifying the fused metal and the vapor remains to be foams. By restricting a carbon amt. of a coating agent to 0.02-0.50 wt.% per the whole coating agent, the oxidizing force of the fused metal is made proper to promote the oxidation of the zinc, that is, to raise a temp. of the fused metal due to oxidation reaction heat for suppressing the generation of the zinc vapor, further, the gas discharge is promoted by strengthening the agitation action of the fused metal to reduce the influence of the zinc and thus, the generation of a welding defect is prevented.

Title: Underground installing synthetic resin pipe
Inventor: SOGI TADAYUKI
IPC: G01V3/00
Filed: 1997-01-17
Abstract: PROBLEM TO BE SOLVED: To easily detect the position of an underground installing synthetic resin pipe from a surface ground without using any locating wire and so on. SOLUTION: An underground installing synthetic resin pipe 1 forms a conductive PE layer 3 in an inner surface of an electric insulating PE layer 2. When this synthetic resin pipe 1 is fused by an electric fusion process, the conductive PE layer 3 on the inner surface is also fused for attachment, and an electrical connection between two underground installing synthetic resin pipes 1 is carried out simultaneously with a mechanical connection. If an AC current is made to flow into the conductive PE layer 3, a magnetic field generated in the circumference is detected from a surface ground and thereby the positional detection is thus performable.  In addition, when a position probe takes place in use of an underground probe radar from the surface ground, the extent of radio wave reflecting strength from the conductive PE layer 3 grows larger, so that this positional detection is easily performed.

Filed: 1981-01-21
Abstract: PURPOSE:To optimize controlling of thickness of a sheet by properly interchanging a gauge-meter system with a feed-forward system mutually for utilizing their chracteristics efficiently. CONSTITUTION:An interchanging device 36 switches basing on a sheet thickness deviation 39 produced by a setting valve 42 given to a press-down control device 37 which is derived from a rolling load 41, or switches basing on a sheet thickness deviatin 40 detected at a stand in the upstream side. The discrimination of interchanging is based on the sheet-thickness deviation, detected at the upper- stream-side stand, by a discrimination device 35. Under the condition that the variatin of sheet thickness is expected; a feed-forwad system is adopted when high-frequency components, which cause the delay under a press-down controlling system, are large, and a gauge-meter system is adopted when said components are small. As a discriminating method for quantity of high-frequency components is whether large or small said method is performed from the distribution of said componetns, obtined from the components of the sheet thickness deviation, detected at the present time. Further, for the thickness variations presently detected, the discrimination is performed from the rate of varying quantity which exceeds a fixed value, by checking said quantity per unit time.
