Patent number: 6662719Abstract: A thermosensitive stencil sheet including at least a thermoplastic resin film and an electromagnetic wave absorbing layer which includes an electromagnetic wave absorbing agent and a resin. The thermosensitive stencil sheet may also include a porous substrate and/or a protective layer. A thermal stencil printing method in which the thermosensitive stencil sheet is imagewise perforated with an electromagnetic wave to prepare a stencil plate and then the resultant stencil plate is subjected to a printing operation to form images is also provided. A multi-color thermal stencil printing method using the thermosensitive stencil sheet is also provided.Type: GrantFiled: January 8, 1999Date of Patent: December 16, 2003Assignee: Ricoh Company, Ltd.Inventor: Hiroshi Adachi

Patent number: 6659003Abstract: A perforation pattern is provided with a stencil plate, which is decreased in perforation configuration irregularity and has an adequate size of perforations. The stencil plate is produced from a heat sensitive stencil sheet having a heat shrinkable film by selectively heating the film with a heating device to form independent dot perforations corresponding to an image in the film, and each of the perforations has a through hole and a rim surrounding the through hole and bulging on a heated side of the film, and the rim has a height that satisfies the following formulae (1) and (2): h≦4 (&mgr;m) (1) h≦0.05{square root over ( )}(pxpy)(&mgr;m) (2) where h denotes the height (&mgr;m) in reference to the surface of the film before heated, px and py respectively denote pitches (&mgr;m) in main and sub scanning directions of the heating device.Type: GrantFiled: September 27, 2002Date of Patent: December 9, 2003Assignee: Riso Kagaku CorporationInventors: Jun Nakamura, Shoichi Ikejima

Patent number: 6634288Abstract: A stamp member 11 includes a porous resin 101 and a film 103 adhered together by an acrylic adhesive 102. The film 103 is peeled from the porous resin 101 after stamp making operations have been completed for forming a stamp image on a stamp surface 71 of the porous resin 101. Therefore, the stamp surface 71 of the porous resin 101 is protected from fine dirt and dust. Also, because there is no need to proved a film between a stamp making device and the stamp member 11 at stamp making operations, stamp making operations are simplified.Type: GrantFiled: July 6, 2000Date of Patent: October 21, 2003Assignee: Brother Kogyo Kabushiki KaishaInventors: Teruo Imamaki, Takashi Miki, Teruyo Katsuno, Koji Sugiyama

Patent number: 6572951Abstract: A printing sheet which prevents setoff while transferring a sufficient quantity of ink and maintains necessary dot uniformity can be obtained by ensuring characteristics that the centerline average roughness showing the larger value is 1.0-3.5 &mgr;m and the ratio of centerline average obtained by dividing the larger value by the smaller value is less than 1.15 where said values are chosen at the point where the difference between the centerline average roughness in a certain direction and the centerline average roughness at right angles to said direction is maximal. Further, the abovementioned quality is further improved by appropriately ensuring that the oil absorbability is more than 4 mg/cm2 and less than 7 mg/cm2 when the contact time between the oil component having a surface tension of 27-30 mN/m at 20° C. and the printing sheet is 5 seconds and/or that the median pore diameter is 1.7-3.5 &mgr;m, in addition to the abovementioned characteristics.Type: GrantFiled: March 28, 2001Date of Patent: June 3, 2003Assignee: Nippon Paper Industries Co., Ltd.Inventors: Makoto Hasegawa, Noriko Kumazawa, Akinobu Chatani, Nobuo Nakanishi, Ryuta Ono, Hiroki Yamamoto, Teruaki Ookawa, Yasuo Yamamoto
