Title: Fire-resistant wire and cable
Inventor: TANMACHI MASAMI
IPC: H01B3/44
Filed: 1988-01-12
Abstract: PURPOSE:To improve waterproofness and leave a hard, fire-resistant, non- halogen residue after burning by laying a covering layer having a plurality specific composition of materials on the outer periphery of at least one insulated strand. CONSTITUTION:The covering layer of a cable is composed of a composition of materials contains 30-250 weight parts of an inorganic hydrate and 0.2 and more weight parts of a treated olefin monomer in comparison with 100 weight parts of polyolefin. Here the treated substance is produced by being submitted to plasma treatment as a fire resistant assistant for polyolefin in a system devoid of enzymes to provide olefin monomers, and by polymerizing and spreading those olefin monomers on a red phosphorus surface. The covering layer is applied to the exterior of at least one insulated strand of a cable and crosslinked. Forming olefin monomers upon the red phosphorus surface improves waterproofness. In addition, maintaining the composition of the inorganic hydrate within the above range enables a hardened residue to be left after burning, thus to produce a fire-resistant non-halogen cable.

Abstract: PROBLEM TO BE SOLVED: To reduce a turn-off loss sufficiently by causing the first impurity concentration of a fifth impurity region, the second impurity concentration of a sixth impurity region, and the impurity concentration of the second main surface of the fourth impurity region to satisfy a specific formula, and to cause the depth of diffusion of the fifth impurity region from the second main surface to the fourth impurity region to be a specific value or more. SOLUTION: The p-type collector region 3 of an IGBT element has a p-type impurity region 3a and a p<+> impurity region 3b. The impurity concentration Cs(p) in the collector surface of the p-type impurity region 3a is lower than the impurity concentration Cs(p<+> ) in the collector surface of the p<+> impurity region 3b. Besides, the depth of diffusion from the collector surface of the p-type impurity region 3a is smaller than that from the collector surface of the p<+> impurity region 3b, and is 2.0μm or more. Each impurity concentration is set so as to satisfy the relation represented by the formula, when the impurity concentration in the collector surface of an n-type buffer region 2 is represented as CS(nbuf) . Consequently, it becomes possible to reduce the turn-off loss of the IGBT element too.
