Title: Method and device for shrinking shrinkable cover covered on deposition of article
Inventor: RAINAA BUIRUHERUMU HANEN
IPC: B65B53/06
Filed: 1983-12-23
Abstract: In order to package a stack of goods in an envelope of heat-shrinkable plastic material such as polyethylene, with prevention of adhesion between the envelope and the goods which may themselves be wrapped in similar sheet material, the stack is placed on a pallet and is covered by the envelope whose lower rim is clamped between the legs of the pallet and an apertured supporting surface such as an upper run of a chain conveyor. The envelope is then inflated from below, by way of the supporting surface, with a low-temperature gas such as ambient air, to establish significant clearances between the stack and the inner surface of the envelope which is then thermally shrunk around the stack by training jets of hot gas onto its outer surface. In zones where the envelope is in contact with the stack, as along edges of the latter, the heating intensity may be reduced to avoid fusion with individual wrappings.

Title: Magnetic roll
Inventor: YAMASHITA KEITARO
IPC: G03G15/09
Filed: 1990-09-13
Abstract: PURPOSE:To directly attract a magnetic developer on the surface of a permanent magnet and to carry it by integrally forming a cylindrical permanent magnet and the supporting shafts of both end pats of a material containing ferromagnetic powder and high strength resin and specifying volume specific electric resistance. CONSTITUTION:The volume electric resistance of the surface of the cylindrical permanent magnet is 10<6>-10<14>OMEGA.cm, preferably 10<10>-10<13>OMEGA.cm. However, when this value is too big, a bias can not be got, a developing current does not flow and image density is lowered, so that it is not desired. On the other hand, when the volume electric resistance is too small, fogging is caused, and image quality is lowered so that it is not desired. The value of this volume electric resistance can be adjusted by the added amount of a conductive material such as carbon black, metallic powder, and metallic (alloy) magnetic powder at the time of kneading materials. The magnetic roll is formed by integrally molding a kneading material principally composed of, for example, the ferromagnetic powder and the high strength resin by a molding means for an extrusion molding or an injection molding, and cooling, hardening, magnetizing it.
