Patent number: 9546801Abstract: A solar-thermal conversion member includes a ?-FeSi2 phase material. The solar-thermal conversion member exhibits a high absorptance for visible light at wavelengths of several hundred nm and a low absorptance for infrared light at wavelengths of several thousand nm and, as a consequence, efficiently absorbs visible light at wavelengths of several hundred nm and converts the same into heat and exhibits little thermal radiation due to thermal emission at temperatures of several hundred ° C. The solar-thermal conversion member may therefore efficiently absorb sunlight, provide heat, and prevent thermal radiation due to thermal emission.Type: GrantFiled: November 9, 2012Date of Patent: January 17, 2017Assignees: Toyota Jidosha Kabushiki Kaisha, Japan Fine Ceramics Center, Kabushiki Kaisha Toyota JidoshokkiInventors: Akinori Sato, Yoshiki Okuhara, Seiichi Suda, Daisaku Yokoe, Takeharu Kato, Toru Sasatani

Patent number: 8539757Abstract: An exhaust purification apparatus for an internal combustion engine according to the present invention includes a heated gas generation apparatus configured to generate heated gas utilizing exhaust gas flowing through an exhaust passage. The heated gas generation apparatus includes a catalyst configured to provide an oxidation function, a fuel supply nozzle, and a heater. An exhaust purification unit is provided downstream of the heated gas generation apparatus. An incoming gas temperature of the exhaust purification unit is detected and estimated. An actual incoming gas temperature being a detected value and an estimated incoming gas temperature both acquired when at least the fuel supply nozzle is actuated are compared with each other. Based on the result of the comparison, the apparatus detects one of poisoning of the catalyst with HC and degradation of the catalyst. Thus, the heated gas generation apparatus is prevented from discharging HC.Type: GrantFiled: January 14, 2010Date of Patent: September 24, 2013Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinya Hirota, Toru Sasatani, Sakutaro Hoshi, Hiroshi Fujimoto
