Title: Exhaust gas piping for exhaust gas cooler
Inventor: IKEGAMI YASUSHI
IPC: F23G7/06
Filed: 1989-11-08
Abstract: PURPOSE:To contrive simplification of a cooling gas supply equipment, labor savings and alleviation of heat load, by connecting a cooling gas inlet pipe to an outer pipe, and making a pipe space between the outer pipe and an inner pipe communicate with a space on the outside of an exhaust gas circulating pipe. CONSTITUTION:A cooling gas enters a space between an inner pipe 44 and outer pipes 14, 46 constituting a heat exchanging part, and is heated through heat exchange with a high-temperature exhaust gas circulated through the inner pipe 44. The tempera ture to which the cooling gas is heated depends on the flow rate of the cooling gas supplied, the shape and size of the heat exchanging part, the connection position of a cooling gas inlet pipe, the exhaust gas temperature and the like, and is controlled by the flow rate. The cooling gas heated to an appropriate temperature is fed into an exhaust gas cooler 40, and is ejected through cooling gas ejecting holes 16 to cool the high-temperature exhaust gas. Therefore, exhaust gas components are prevented from being condensed or deposited, and the exhaust gas cooled is fed through an exhaust gas piping 42 to an exhaust gas treating device. Thus, a simpler construction is achieved, and heat load (cooling of the exhaust gas) on the exhaust gas treating device on the downstream side is alleviated.

Title: Image receiving sheet
Inventor: HAYASHI MASAFUMI
IPC: G03G7/00
Filed: 1998-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain an image receiving sheet which ensures good toner fixability, always gives high quality images, little in environmental dependency which keeping constant surface resistivity and is used even in an electrophotographic system in which silicone oil is not used for toner fixation. SOLUTION: A layer containing fine metal particles and/or an electrically conductive polymer having π-electron conjugated double bonds and a binder is disposed on, at least, one surface of a substrate 1 to obtain the objective image receiving sheet. Since fine metal particles and/or an electrically conductive polymer is used, the surface to be coated is not sticky nor transferred to a contacting surface during storage, thus causing no change of the surface resistivity. Since the fine metal particles and/or the electrically conductive polymer are not an ion-conducting material, the surface resistivity dies not vary even when the environment (temperature, humidity) around the sheet varies. The sheet ensures good toner fixability, is excellent in image quality and has good suitability to transport in an electrophotographic copying machine and a printer.
