Title: Trolley line
Inventor: IKEDA TOSHIYA
IPC: B60M1/30
Filed: 1996-12-04
Abstract: PROBLEM TO BE SOLVED: To attain weight reduction and stable mechanical characteristics by forming a reinforcing core out of mainly alumina fiber in a trolley line conductor part consisting of conductive metal in a trolley line. SOLUTION: A reinforcing core 3 is distributed unevenly at the upper part of the inside of a trolley line conductor part. In the reinforcing core 3 whose cross-section is elliptic, alumina fiber 5 is disporsely-disposed inside an impregnated material 4. The percentage content of the alumina fiber 5 in the reinforcing core 3 is 50% area ratio, and the area ratio of the almina fiber in the trolley line cross-section is 20%. For the manufacture of the reinforcing core, the alumina fiber is immersed in fused aluminum and drawn out from a die having an elliptical hole for solidification. Compounding of the reinforcing core and the conductor part is conducted by bonding aluminum at the periphery of the reinforcing core by a continuous extruder.  In the trolley line of this structure, the reinforcing core 3 is distributed unevenly at the upper part even if the lower part of the trolley line is worn, so that all of it survives. It is thus possible to have excellent tension load after being worn.

Title: Sensitized material containing magazine
Inventor: MATSUDA NAOYUKI
IPC: B65H1/04
Filed: 1989-12-28
Abstract: PURPOSE:To prevent the occurrence of a hindrance to light shielding ability even during remounting of a cover by using a material having low stretchability for the tip part of a light shielding sheetform cover mounted to an opening surface and using a material having high stretchability for other part of the cover. CONSTITUTION:Since a material having high stretchability is used for a body part 41d of a cover 41, adhesion to a flange part 13a of a magazine 13 is excellent. Since a material having low stretchability is used for a tip part 41b, there is no fear of high peeling exerted during the starting of winding being increased to a full value, and during rewinding, re-adhesion to a tip flange part 13' is effected without provision of a gap. Especially, at the tip flange part 13a', wrinkles in the directions of arrow marks c and c' are apt to generate at a cover 41, but since a material having low stretchability is used for a tip part l4b, the generation of the wrinkles is prevented.
