摘要： A method for testing a multicore cable that includes a single common shield covering plural insulated wires. The testing method includes inputting a test signal, by capacitive coupling, to an end portion of the insulated wire under test among end portions of the insulated wires exposed at one end of the multicore cable, and measuring voltages of output signals output by capacitive coupling respectively from end portions of the insulated wires exposed at the other end of the multicore cable, and identifying the other end portion of the insulated wire under test based on the measured voltages. The voltages of output signals are measured in a state that an output variation reduction capacitive element is connected in series with a coupling capacitance generated by the capacitive coupling.

摘要： The present invention relates to a pinch detection switch (1) that includes one tubular pressure-sensitive detection member (5) having a plurality of electrode wires spaced apart from one another, and a cover member (4) covering the pressure-sensitive detection member. When the cover member (4) is viewed in cross section, the cover member (4) includes a base portion (4-1), a hollow portion (6), and a deformation portion (4-2) provided on the base portion (4-1) so as to cover the hollow portion (6). The pressure-sensitive detection member (5) is arranged in the deformation portion (4-2), and a receiving portion (9) configured to receive the pressure-sensitive detection member (5) is arranged on the base portion (4-1). The receiving portion (9) has at least two receiving surfaces (9-1, 9-3) formed at positions facing the pressure-sensitive detection member (5), the two receiving surfaces being configured to receive the pressure-sensitive detection member.

摘要： An insulated electric wire is composed of a conductor composed of a copper material, and an electrical insulating layer provided on an outer periphery of the conductor. For the constituent conductor of the insulated electric wire, in an orientation intensity ratio obtained by X-ray diffraction of a transverse cross section of the conductor, an intensity in a [200] crystal orientation is higher than an intensity in a [111] crystal orientation.

摘要： An edge processing device includes: conveying means that convey a molded powder compact, a first rotating tool disposed on one side and a second rotating tool disposed on the other side and rotating in a direction identical to a direction the first rotating tool rotates. The first rotating tool contacts from an upstream side with a first corner portion between one side surface of a processing target portion of the molded powder compact and a rear surface of the processing target portion. The second rotating tool contacts from a downstream side with a second corner portion between the other side surface of the processing target portion and a front surface of the processing target portion. The second rotating tool faces the first rotating tool with the conveying path therebetween, and is positionally displaced to the downstream side with respect to the first rotating tool.
