Patent number: 5698012Abstract: An exhaust gas purifying apparatus capable of exhibiting an excellent exhaust gas purifying capability and restoring the capability to an initial level even after running for a long period of time. An electrification mesh section electrostatically negatively charges useless particulates contained in exhaust gas and a purification filter section adsorbs thereon the particulates thus charged, resulting in the particulates being separated from the exhaust gas. Also, when the purification filter is made of carbon fiber or carbon particles or the denitration filter section is additionally provided, a reduction in concentration of nitrogen oxides in the exhaust gas is accomplished as well. In a reactivation unit, cleaning liquid cleans the purification filter section to remove useless particulates therefrom, so that an exhaust gas purification capacity of the exhaust gas purifying apparatus may be restored to a level substantially equal to an initial level thereof.Type: GrantFiled: March 25, 1996Date of Patent: December 16, 1997Assignee: Ajiawasu Kabushiki KaishaInventor: Hideo Yoshikawa

Patent number: 5052513Abstract: In order to accomplish the aforementioned and other objects, a resin muffler, according to the invention, is formed of a heat-resistantive synthetic resin having a property of visco-elastic plasticity in a predetermined temperature range. In the visco-elastic temperature range, the motion of the molecular chain segment of the material resin comes to be relaxed to exhibit noise creative pulsating energy dissipation owing to emission as heat energy. Since the resin muffler thus absorbs noise creative energy by dissipation at around the visco-elastic temperature range and transform the energy into the heat energy which may be emitted by radiation.Type: GrantFiled: November 25, 1987Date of Patent: October 1, 1991Assignees: Showa Denko Kabushiki Kaisha, Yamato Kogyo Company, LimitedInventors: Hideo Yoshikawa, Katsuyoshi Takeuchi, Masami Shimada, Yoshiharu Awaji, Takashi Ikeda, Shunsaku Mitsuno
