Publication number: 20020021997Abstract: Through the formation of an organic polymer film on the surface of a bare graphite sheet by electrodeposition or through the application of a resin film to the surface thereof, a good-quality coated graphite sheet of uniform thickness which has excellent electric insulation and a low thermal resistance and prevents graphite powder from separating while retaining thermal conductivity and flexibility of the bare graphite sheet can be provided. The organic polymer film is formed by electrodeposition from a resin selected from the group consisting of an anionic electrodeposition resin, a cationic electrodeposition resin, a thermosetting electrodeposition resin and a UV curing electrodeposition resin or is formed of polyimide. The resin film is applied by a method selected from the group consisting of dipping, spin coating, screen printing, brushing and spraying, using at least one resin selected from the group consisting of an epoxy resin, a polyimide resin and a fluororesin.Type: ApplicationFiled: June 12, 2001Publication date: February 21, 2002Inventors: Akira Taomoto, Kenji Akami, Yasuo Kudo, Hiroki Takeoka, Toshiharu Saito, Souji Tsuchiya

Patent number: 5861556Abstract: A plurality of flow velocity sensors are vertically installed in line at different positions in the same cross section in a gas flow passage in a pipe. Detection signals from the flow velocity sensors are inputted to a mean flow velocity computing unit which calculates a mean value of flow velocity measurements. The mean flow rate calculated at the mean flow velocity computing unit is converted into a flow rate by a flow rate computing unit to be displayed by a display. Regardless of flow velocity distribution in the pipe, which may change due to differences in the pipe shape, flow rates are accurately measured. As a result, flow rates are accurately measured over a wide range.Type: GrantFiled: November 12, 1996Date of Patent: January 19, 1999Assignee: Tokyo Gas Co., Ltd.Inventors: Kazumitsu Nukui, Toshiharu Saito, Tokudai Neda
