摘要： PROBLEM TO BE SOLVED: To fix a heat pipe rigidly to a thermal transmittance member without producing any deformation (strain) in it. SOLUTION: A heat pipe 5 having working liquid sealingly enclosed therein is inserted into and passed through a heat pipe insertion hole 1 of the thermal transmittance member 4 with a part of the heat pipe 5 being exposed. When the heat pipe 5 is thermoplastically deformed in its diametrically expanding direction, an exposed portion 6 of the heat pipe 5 is arranged at a heat pipe fixing hole 8 of a fixing jig 7, and the heat pipe 5 is heated to cause a thermoplastic deformation to be attained in a diametrically expanding direction. Since the exposed portion 6 of the heat pipe is fixed at the heat pipe fixing hole 8, the exposed portion 6 of the heat pipe is prevented from being deformed (strained). When the heat pipe fixing hole 8 is machined in a high precision, a size accuracy of the exposed portion 6 of the heat pipe is improved. Since the expanded diameter of the exposed portion 6 is restricted by the fixing hole 8, the heat pipe 5 is well expanded in its diameter within the heat pipe insertion hole 1, and an anti-pulling characteristic of the heat pipe 5 from within the insertion hole 1 is improved.

摘要： PROBLEM TO BE SOLVED: To obtain a collecting slider which causes a trolley wire to be less worn, which makes it possible to improve the conducting capability between a carbon sliding part and a collector shoe, and which is easy to mount. SOLUTION: A collecting slider is structured with a sliding part 1 which contact a trolley wire and a reinforcing part 2 formed solidly by impregnating light metals in the reinforcing part 2 into the gaps of carbons contained in the sliding part 1 made of porous carbons. Also, it is possible to strengthen the bond between the reinforcing part 2 and light metals by implanting metal fibers into the carbons or to fill fibrous reinforcing members into the light metals of the reinforcing part. To manufacture the slider above, porous carbons or porous carbons containing metal fibers, and fibrous reinforcing members when required, are laid inside a mold in advance. Then, molten light metals are filled with pressure into the mold above to be impregnated into or welded onto the carbons or carbons containing the metal fibers.

摘要： PURPOSE:To prevent the damage of a primary coil and improve the durability of a furnace by a method wherein refractory material having non-reactive property against molten metal is employed for an outside refractory material layer which is in contact with the molten metal while permeation resistant refractory material, through which the molten metal is hardly permeated, is employed for the inside refractory material layer. CONSTITUTION:In a groove type induction furnace, in which a primary coil 4 arranged on the bottom of the inside of the furnace is excited by AC current to generate induction current in molten metal 1 in the outer peripheral groove 6 of the primary coil and heat the molten metal through the resistance thereof, magnesia refractory material is used for an outside non-reactive refractory material layer 2 while high-alumina refractory material is used for an inside permeation resistant refractory material layer 3. The non-reactive refractory material is used for the outside layer 2 in contact with the molten metal in such a manner whereby slug will never be generated on the surface of the refractory material and the molten metal will never be permeated into the inside of the layers even when the molten metal is permeated through the refractory material and arrives at the inside refractory material layer 3 since the inside refractory material is prominent in permeation resistant property. Further, the amount of molten metal arriving at the inside refractory material layer 3 is small even when the slug is generated whereby the slug is formed on the surface of the layer as a thin film and thick film of the same will never be produced. Accordingly, the damage of the primary coil 4 can be prevented.
