Patent number: 8336527Abstract: A solenoid switching valve is provided at a low concentration gas pipe that sends gas from a second separating film unit to a canister. A reflux pipe, that is branched-off from the low concentration gas pipe by the solenoid switching valve, merges with a medium concentration gas pipe that is from the second separating film unit, and further runs via a circulating pipe, and reaches a merge portion with a purge pipe from the canister. By switching the solenoid switching valve to the merge portion side and driving a purge pump that is provided at an exhaust pipe between the merge portion and a first separating film unit, gas, whose concentration has risen within the low concentration gas pipe, is sent to the first separating film unit, and is separated into high concentration gas HG and low concentration gas LG.Type: GrantFiled: November 19, 2010Date of Patent: December 25, 2012Assignee: Aisan Kogyo Kabushiki KaishaInventors: Shuichi Aso, Takashi Nagai

Publication number: 20120312281Abstract: An evaporated fuel treatment apparatus is mounted in a vehicle having an engine, a fuel tank storing fuel for the engine, and a battery, the evaporated fuel treatment apparatus adsorbing evaporated fuel in the fuel tank on an adsorbent in a canister container, desorbing the evaporated fuel adsorbed on the adsorbent therefrom during engine running, and directing the evaporated fuel to an intake passage of the engine. The adsorbent in the canister is heated by heat generated by the battery.Type: ApplicationFiled: June 5, 2012Publication date: December 13, 2012Applicant: AISAN KOGYO KABUSHIKI KAISHAInventors: Hidetoshi TSUTSUMI, Yuji TAKASHIMA, Kensuke NAGAO

Patent number: 8327964Abstract: A canister is provided which efficiently purges in a saddle-riding type vehicle having an engine disposed downwardly of a rider seat so as to develop a drive power for driving a rear wheel, a fuel tank storing fuel to be supplied to the engine, and a canister adsorbing fuel vapors generated in the fuel tank. An air guide path that guides exhaust air discharged rearwardly from a radiator, which circulates coolant with an engine, is formed inside a vehicle body cover. The canister is disposed in the air guide path.Type: GrantFiled: March 17, 2010Date of Patent: December 11, 2012Assignee: Honda Motor Co., Ltd.Inventors: Hiroshi Inaoka, Takeshi Shimura

Patent number: 8323450Abstract: The invention relates to a method of manufacturing a heat storage material that contains heat storage capsules. The heat storage capsules include a phase change material that absorbs and/or discharges latent heat in response to a change in temperature. The phase change material resides within outer shells of the heat storage capsules. The method involves binding abutting peripheral portions of a plurality of heat storage capsules with a molding binder, so as to form an intermediate granular molded heat storage material. An outer peripheral surface portion of the granular molded heat storage material is coated with a coating binder. The coated granular molded heat storage material is then subjected to a treatment that causes the coating binder of the coating layer to polymerize. The invention also relates to heat storage adsorbent materials, and articles (e.g., canisters) that include such heat storage adsorbent materials.Type: GrantFiled: April 22, 2009Date of Patent: December 4, 2012Assignee: Osaka Gas Chemicals Co., Ltd.Inventor: Kenji Seki
