摘要： PROBLEM TO BE SOLVED: To allow a heating member having a wide heat absorbing surface to efficiently radiate heat by a method wherein a heat pipe is fixed to a fin which is fixed from the heating member to the heat absorbing surface in a substantial vertical direction, the fin is provided with a grid-like cooling medium flow passage and an end part of the heat pipe at the heat absorbing surface is inserted into the heat absorbing surface. SOLUTION: A heat pipe type radiator A is fixed to a heat absorbing surface 1 of rectangular shape such as a Peltier element or the like in a substantial vertical direction, a plurality of fins 2 are spaced apart by a predetermined distance and arranged in side-by-side relation, they are equally spaced apart within the fins 2 and then a plurality of heat pipes 3 are buried. The fins 2 are flat plates formed by metal of superior thermal radiating characteristic such as aluminum or the like and it has a grid-like cooling medium flow passage. The heat pipe 3 is made such that working liquid is enclosed while its pressure being reduced in a metallic pipe with both ends being sealingly enclosed, wherein the heat pipe 3 is extended from the heat absorbing surface 1 in a substantial vertical direction and its base end is buried in the heat absorbing surface 1. With such an arrangement as above, it is possible to perform an efficient thermal radiation even in the case that the heat absorbing surface of the heat generating member is wide.

CONSTITUTION:Molding material consisting of polyisocyanate and activated hydrogen compound contains electro-conductive carbon black as auxiliary material. An electro-conductive plastic molded item is produced by injecting the above-mentioned auxiliary material-containing molding material in a mold for reaction-hardening. As the above-mentioned electro-conductive carbon black, the one, the whole of which passes through a screen having 200 mesh or less and 80% and more of which passes through a screen having 325 mesh or less, is used. The electro-conductive carbon black consisting of said fine particles is added to either one or both of polyisocyanate and activated hydrogen compound for mixing. The compounding amount of the electro-conductive carbon black at this time is preferably 0.5% or more and 5% or less with respect to the weight of the plastic molded item.

摘要： PURPOSE:To increase the productivity of polyurethane resin by a method wherein the predetermined equivalent amounts of long-chain polyol, di-isocyanate and low-molecular diol are directly charged in an extruder so as to be successively heated up to specified temperatures and mixed in the extruder in order to successively and continuously synthesized urethane and plasticize it and finally extrude it in the form of pellets. CONSTITUTION:From a hopper C, the mixture of the predetermined equivalent amounts of chain caprolactam and 4,4'-diphenylmethane diisocyanate is poured in a double-screw extruder A having vent holes D. Further, 1,4-butanediol is forced at the position apart by seventh pitch from the hopper of the extruder by means of a pouring pump J in the extruder. After that, the resultant mixture is transferred to a plasticizing zone are held at 150 deg.C in a strand die F provided at the outlet of the extruder. By charging the resultant pellets to an injection molder, a sheet having favorable physical properties is obtained.

摘要： PURPOSE:To contrive to improve mounting workability and safety by equipping a pole-fixing hardware, guide arm, slide arm, table-supporting member and working table. CONSTITUTION:The vertical position and the circumferential angular position of a working table 1 relative to a pole 14 are determined approximately and a pole-fixing hardware 15 is fixed in that position. Then, a guide arm 19 and slide arm 20 are set to a suitable length and coupled together, an adapter 16 is attached to the guide arm 19 and they are lifted as an integral member, and the adapter 16 is integrally mounted on a baseplate 17. Subsequently, a working table-supporting rod 4 is inserted in a working table bracket 21 and a fixing screw 42 is driven temporarily. Thus, permanent fixing for cable connection is performed, after a cable connection table is temporarily fixed to the pole 14. In this manner, it is possible to improve the mounting property and safety of a pole-mounted type work bench.
