Abstract: A contact is formed of a tip end portion (11) approximately cylindrical as a whole in shape, having at one end a contact end to come into contact with a circuit under test, and a base portion (12) provided to be opposed to and kept apart from the other end that is opposite to the contact end of the tip end portion. By pressing the tip end portion into contact with a circuit under test (20), the tip end portion and the base portion are brought into contact with each other, and further pushing causes dislocation at the contact surfaces (14,15) so that the tip end portion is moved in a direction parallel to a surface of the circuit under test. Therefore, when the contact probe is pressed into contact with the circuit under test, the contact end of the contact probe is moved such that it scrapes off the surface of the circuit under test to break the insulating film on the surface, resulting in reliable contact with the circuit under test.

Abstract: Disclosed is an electrical insulating laminated paper prepared by a process which comprises the steps of melt-extruding a polyolefin resin as a binder onto one or two sheets of a kraft insulating paper by means of a extruder to obtain a laminated paper, and calendering or supercalendering the laminated paper so that the total thickness thereof is from 30 to 200 mu m and the proportion of a polymer comprising the polyolefin resin is from 40 to 90%. The laminated paper is excellent in dielectric properties, dielectric strength, and mechanical properties such as adhesive strength.

Abstract: In a solid DC cable formed of a conductor (1, 21, 41) and an insulating layer provided on an outer circumference of a conductor, the insulating layer is constituted by one of: (A) a main insulating layer (4), and a low-resistance tape layer (2) comprising carbon paper having a volume resistivity which is smaller by one or more figures than that of the main insulating layer (4) (Fig. 1); (B) a main insulating layer (23) comprising kraft paper (23A), and a low-resistance insulating layer (23B) comprising low-resistance kraft paper having a resistivity smaller than the kraft paper (23A) of the main insulating layer; (C) a main insulating layer (43) comprising a composite tape in which low-loss plastic film and kraft paper (43A) are bonded, and a low-resistance insulating layer comprising kraft paper (43B) having a resistivity lower than the main insulating layer; and (D) a low-resistance tape layer (2) comprising carbon paper, a low-resistance insulating layer comprising the low-resistance kraft paper (23B), and a main insulating layer (23A) which is successively provided from the conductor side to the main insulating layer side. In the solid DC cable, the low-resistance insulating layer (23B, 43B) and the low-resistance tape layer (2) are provided just above the conductor (1, 21, 41) in a region where the pressure of insulating oil becomes negative when a load is cut off.

Abstract: A circuit board comprising a patterned first metal layer 14 formed on a ceramic substrate 11, a patterned second metal layer 16 formed on the first metal layer, and a third metal layer 17 formed covering the entire upper surface and side surfaces of the second metal layer and a part of the upper surface of the first metal layer, wherein portions of the first metal layer not covered by the third metal layer are reduced in width by etching. The circuit board has thick-film fine wiring patterns with high bonding strength between the wiring patterns and the substrate and high reliability and enables realization of high-output modules which are small in size and high in performance, by mounting at least one high-output semiconductor element thereon.
