Abstract: A minutely working method of and apparatus for opposing the surface of a transfer member having a concave or convex pattern formed on the surface thereof and the surface of a workpiece to each other, heating the transfer member and thermally expanding the transfer member in the direction of a normal to the surface thereof to thereby transfer the concave or convex pattern to the workpiece.

Abstract: A process for producing a tubular article is provided which, comprising winding a first thermoplastic sheet film on a cylindrical member with the wind-starting portion and the wind-ending portion thereof overlapped, placing a metal tube outside the above wound film either (a) by winding a metal sheet with both of the sheet ends thereof abutted or (b) by fitting a metal tube, winding a second thermoplastic sheet film on the metal tube with the wind-starting portion and the wind-ending portion thereof overlapped, fitting a tubular member outside the wound second thermoplastic sheet film, and heating at least the first and second thermoplastic films to bond the overlapped portions of the thermoplastic sheet films. The tubular article produced according to the present invention has significantly improved film properties such as heat resistance (thermal expansion, break strength at high temperatures, etc.

Abstract: A tubular film for fixing a unit of an image forming apparatus. Includes a rib portion as an engage portion at its one end. For forming the rib portion, a groove is provided at an end of a cylindrical member, as an inner mold, and/or a tubular mold member as an outer mold, and a film to be the rib is rolled along the groove.

Abstract: Provided is a method of manufacturing a cylindrically shaped article, wherein a thermoplastic layer is formed on the surface of the cylindrically shaped article precisely and at low cost. To achieve this, the outer peripheral surface of a cylindrically shaped article supported on a columnar member is coated with particles of a thermoplastic resin, a tubular molding member is fitted on the cylindrically shaped article coated with a film of the particles of thermoplastic resin, and at least the columnar member is then heated to calcine the thermoplastic resin film.

Abstract: A tubular film having a high film thickness uniformity and suitable for a fixing film of an image forming apparatus is provided. To achieve such a film, a thermoplastic sheet film is so wound that the leading and trailing end portions of the film partially overlap each other to form overlapping portions, and the wound film is heated between a core member and a tubular molding member.

Abstract: A plastic molded article has an external appearance of a coated article and is formed by injection molding using a mold with a surface shaped by forming machining marks in the form of recesses over the entire mold surface. The resulting plastic molded article has a center line average roughness of the surface shaped of the plastic molded article less than 0.5 .mu.m and one of either an average slope within the range of 1.0.about.10.0.degree. or an average peak-to-peak interval within the range of 5.0-30.0 .mu.m.
