Patent number: 6309496Abstract: An improved method and apparatus for making a dual-layer DVD disc that does not require a stamping step (typically, as part of the 2P prior art manufacturing process) during its manufacture. As proposed by Mueller, a polycarbonate substrate is molded and coated with a semireflective data layer in the usual way. A PMMA substrate is molded and coated with a fully reflective data layer. Adhesive is placed on the semireflective data layer, and the fully reflective data layer is transferred from its PMMA substrate to the polycarbonate substrate. The polycarbonate substrate thus ends up with two data layers in conformance with the DVD specifications, and the PMMA substrate can even be recycled for another use. However, instead of using a PMMA substrate that is larger than the polycarbonate substrate as proposed by Mueller, in the invention they have equal diameters.

Patent number: 6284307Abstract: A positive hole transporting layer (14) is formed on an ITO film so as to form a substrate (10). A light emission organic material (20) is formed on the front surface of a convex protrusion portion (18) of a metal sheet (16). The front surface of the positive hole transporting layer (14) and the convex protrusion portion (18) are clamped with a glass plate (22). Laser light is radiated to the interior of the convex protrusion portion (18) through a shielding plate with an opening portion whose size corresponds to the size of the convex protrusion portion (18). The light emission organic material formed on the front surface of the convex protrusion portion (18) sublimates and transfers to the positive hole transporting layer (14). These steps are performed for areas of three color light emission devices.Type: GrantFiled: June 16, 1999Date of Patent: September 4, 2001Assignee: NEC CorporationInventors: Shinichi Fukuzawa, Shigeyoshi Otsuki

Patent number: 6251208Abstract: A structure having fine ribs with a high dimensional precision is used as the rear panel of a plasma display or as a micro organism carrier for use in a chemical device. The present invention aims to provide a method for manufacturing such a structure at low cost. According to the invention, a composite sheet comprises a surface layer of silicone rubber and a base layer of a steel sheet. Grooves are formed in the surface layer, and filled with a paste material. The paste material is cured to form ribs. After a substrate is placed on the surface layer of the composite sheet, the composite sheet is pressed against the substrate from the base layer side, thereby compressing the ribs and adhering them to the substrate. Thereafter, the ribs and the substrate are removed from the composite sheet. As a result, a structure with fine ribs is obtained.Type: GrantFiled: October 29, 1997Date of Patent: June 26, 2001Assignee: Toshiba Machine Co., Ltd.Inventors: Shogo Serizawa, Haruji Hosoi, Hiromi Nakamura, Yutaka Hasegawa
