Title: Insulation processing for winding of rotary electric machine
Inventor: MIZUTANI YUJI
IPC: H02K3/34
Filed: 1993-08-26
Abstract: PURPOSE:To obtain a winding of high overall coefficient of heat transmission with no air trapped in iron core slots by immersing the winding, pre-heated through electric gel method, into varnish at a specific speed in a lateral direction while slanting it by a specific angle to a horizontal plane with a support provided with a slanting part. CONSTITUTION:A winding mounted on a support slanted by 10 deg. is heated by electric gel method. After 20 minutes of heating, when coil temperature rise in slots saturates, the winding is immersed into varnish at a rate about 50mm per minute. The winding is taken out after being immersed for about 20 minutes, when varnish around the coil ends have cured and gelled due to the heat of the winding. Then, the winding is heated at 150 deg.C for 5 hours in a hot blast drying furnace to cure varnish. This enables the varnish filling rate of winding in slots to be 100%, thereby suppressing the winding temperature rise when used for a motor. Further, this covers more damages on winding coil ends caused during processing.

IPC: B41M5/26
Filed: 1984-10-09
Abstract: PURPOSE:To obtain a paper raw thermal transfer, having high strength, favorable thermal conductivity and favorable transfer sensitivity, by impregnating a paper with a resin containing a metallic powder for enhancing thermal conductivity. CONSTITUTION: A paper having a basis weight of about 20 g/m<2> is impregnated with a resin, which may be based on aminoalkyd, alkyd, amino, acryl, polyurethane, polyethylene, polyester or the like.

Title: Inflation film molding method
Inventor: KOTANI TERUMITSU
IPC: B29C48/10
Filed: 1984-10-09
Abstract: PURPOSE:To enable to mold extremely thin film with high longitudinal and lateral strengths at high speed by a method wherein resin is melt-extruded from a die slit, onto the outer peripheral surface of the mandrel forming one side of which concave grooves are arranged in the direction of resin flow. CONSTITUTION:Concave grooves 7 are arranged at the predetermined space intervals in the direction of resin flow onto the outer peripheral surface of a mandrel, which forms one side of a die slit 2'. The tubular resin, which is extruded from the die slit 2' and onto the inner surface of which a large number of convex beads are formed by the concave grooves 7... and which lies within the range 8, closely contacts with a bulb stabilizer 3 at the shoulder part 5a so as to stabilize bulb and to flatten the convex beads to some degree while leaving the history of longitudinal ribs in spite of the possibility of traces of the convex beads and streaking patterns left. Further, the resin is expanded at the predetermined ratio within the range 9. Finally, the resin solidifies itself and turns into film within the range 10, which lies after the frost line 5b of the resin. In this case, because the history remains in spite of the flattening of the convex beads, which occurs by the contact of the shoulder of the bubble in which a large number of the convex beads are formed, against the bubble stabilizer, the tear strength in the traverse direction is heightened.

Title: Formation of sintered alloy layer to cast iron member
Inventor: JINNO SUMIO
IPC: B22F7/08
Filed: 1987-08-26
Abstract: PURPOSE:To satisfactorily sinter and join a sintering alloy layer to a cast iron member by specifying temp. and vacuum state and removing gases from the cast iron member, then lowering a vacuum degree and executing sintering in a nonoxidative atmosphere at the time of sintering and joining an alloy powder molding to the cast iron member. CONSTITUTION:The vacuum degree is maintained at least at 1X10<-3>Torr in a vacuum heat treatment furnace and the cast iron member is heated to the temp. below the liquid phase appearance temp. to nearly completely remove the gases in the cast iron at the time of imposing the alloy powder molding on the cast iron member and sintering and joining the member and the molding. The vacuum degree is then lowered (about 1X10<-2>-2X10<-1>Torr) and the temp. is increased to execute the sintering until the sintering alloy material induces in-solid diffusion. The sintering alloy layer is thereby joined to the cast iron member without generating blister and defective joining therein.
