Patent number: 9643472Abstract: A control part controls a first opening-and-closing part to close either one of a first outside air introduction port and a first inside air introduction port when it is determined that outside air introduced from the first outside air introduction port flows into a passenger compartment through the first inside air introduction port, and controls a second opening-and-closing part to close either one of a second outside air introduction port and a second inside air introduction port when it is determined that outside air introduced from the second outside air introduction port flows into the passenger compartment through the second inside air introduction port.Type: GrantFiled: April 9, 2012Date of Patent: May 9, 2017Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Saburo Sakamoto, Shinichirou Hirai, Masashi Watanabe, Koichi Tabei

Patent number: 9487059Abstract: An air conditioner ECU can set an external air introducing mode and an internal/external air dual mode. Here, the internal/external air dual mode is set by the air conditioner ECU in cases in which the air conditioner ECU judges that there is a warm-up state that is after a start of a heating operation and in which a blow-out temperature of air conditioned wind is in the process of rising, and in cases in which humidity detected by a humidity sensor exceeds a reference humidity that is set in advance.Type: GrantFiled: May 1, 2012Date of Patent: November 8, 2016Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Tabei, Saburo Sakamoto, Shinichirou Hirai

Patent number: 9266406Abstract: When a predetermined seat air conditioning command is provided to air-condition a predetermined seat, a control part allows conditioned-air to be blown off only from an air outlet air-conditioning the predetermined seat as a control for a predetermined seat state. In the predetermined seat state, when a stop command is provided to stop an air conditioning blower, the control part controls the air conditioning blower to stop sending air, and controls at least one air outlet of a plurality of air outlets into an open state, the at least one air outlet air-conditioning the other seat except the predetermined seat.Type: GrantFiled: April 9, 2012Date of Patent: February 23, 2016Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masahiko Morikawa, Koichi Tabei, Koichi Aoishi

Publication number: 20140034266Abstract: A control part outputs a signal demanding an engine start when it is determined that a temperature of cooling water detected by a water temperature detector is lower than a threshold. In a normal state where conditioned-air is blown off to a predetermined seat and the other seats, the control part lowers the threshold according to an increase in a heat amount emitted from an auxiliary heating element based on the operating state of the auxiliary heating element. When a predetermined seat air conditioning command is provided to air-condition the predetermined seat, as a control of a predetermined seat state, the control part controls an opening-and-closing part to close an air outlet and further lowers the threshold rather than the threshold controlled in the normal state.Type: ApplicationFiled: April 9, 2012Publication date: February 6, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Tabei, Keiji Yasui, Koichi Aoishi, Masahiko Morikawa, Yoshimi Iwata

Patent number: 4374727Abstract: An electrostatic sorting apparatus having a multistage sorting unit including a plurality of sorting conveyor belts on sorting plates aligned vertically within a cover housing. Each sorting conveyor belt or plate has a trough-like channel formed thereon for sorting a mixture of insulating particles and conductive particles. The particles of the mixture are subjected to repeated cycles of charging with a negative polarity, being attracted to a high voltage electrode, discharging, and dropping downwardly into sorting and recovering hoppers. Thus, the particles are vigorously elevationally moved between the sorting conveyor belt or plate and the electrode up and down and are finally collected in hoppers. The particles are accordingly uniformly agitated in the channel of the sorting conveyor belt or plate. Thus, the mixture is separated into the hopper with an enhanced quality of compost while fine foreign materials mixed therewith are removed from the compost.Type: GrantFiled: May 27, 1981Date of Patent: February 22, 1983Assignee: Fuji Electric Co., Ltd.Inventors: Takeo Takahashi, Koichi Tabei
