Title: Resistance value homogeneity inspecting method for semiconducting layer of cable
Inventor: SUGIYAMA KEIJI
IPC: G01R19/03
Filed: 1990-11-14
Abstract: PURPOSE:To inspect the presence of a local high-resistance section and improve the reliability on the insulation of a cable by measuring the surface temperature distribution of a semiconducting layer heated by excitation. CONSTITUTION:When electrodes are provided on a rubber/plastic semiconducting layer at a preset interval and charged and the semiconducting layer pinched by the electrodes is excited, if the resistance value of the semiconducting layer has no positional dispersion and is homogeneous, the heating of the semiconducting layer by excitation is homogeneous, and the temperature on the surface of the semiconducting layer rises nearly homogeneously. Some changes occur in the temperature distribution on the surface of the semiconducting layer due to the heat conduction from a high-temperature section to a low-temperature section, the heat capacity of a sample, and the conduction and diffusion of heat from the edge of the sample, and the presence of a local high-resistance section can be judged when the temperature distribution of the semiconducting layer heated by excitation is measured.

Title: Construction of concrete-filled steel pipe member
Inventor: WATANABE KENJI
IPC: E04G21/02
Filed: 1997-10-23
Abstract: PROBLEM TO BE SOLVED: To decrease deformation at the lower part of a square steel pipe when the steel pipe is filled with concrete and to make filling of concrete executable up to a higher layer at a time by a method wherein the sides of the square steel pipe are pressed beforehand toward the inside and deformed into depressed shapes and concrete is hardened under the state where the placement pressure of concrete and the pressure applied on pressing the steel pipe are equilibrated. SOLUTION: When a square steel pipe is filled with concrete, sides 20a and 20b of the square steel pipe are pressed at their centers toward the center of the steel pipe through bearing protuberances 12 and deformed into depressed shapes with jigs 10 pressed beforehand by operation of hydraulic jacks of a pressure device. Therefore, when concrete is placed with pressure into the steel pipe column, the sides 20a and 20b are swelled out toward the outside up to positions where placement pressure produced by self-weight of concrete or the like and the pressure applied on pressing by the jigs 10 are equilibrated, and concrete can be, hardened under the state where deformation in the depressed shape is offset and flatness is restored.  Then, the sides 20a and 20b of the square steel pipe column become resistive against the placement pressure twice as strong as that applied when no deformation is made.
