Publication number: 20160046174Abstract: A radiant heater device includes: a heater main body having a heating portion that generates heat by being supplied with electric power to radiate radiation heat due to the heat supplied from the heating portion; an output control unit that controls an output of the heating portion; and a maximum output determination unit that determines an upper limit of the output of the heating portion depending on a heat load around the heater main body. The output control unit controls the output of the heating portion depending on the heat load not to exceed the upper limit of the output determined by the maximum output determination unit.Type: ApplicationFiled: February 14, 2014Publication date: February 18, 2016Inventors: Yasuhiro SAGOU, Takuya KATAOKA, Asami OKAMOTO, Manabu MAEDA, Koji OTA, Hiroyuki SAKANE, Akira OGA, Masatoshi NAKASHIMA, Hiroshi TAKEDA, Masataka KINOSHITA, Hideaki KAKO, Kimitake ISHIKAWA

Publication number: 20160039265Abstract: A heater apparatus includes a main body, a detecting unit, and a control part. The main body has a power supply part to which electric power is supplied and a heating portion connected to the power supply part to generate heat by electric power supplied from the power supply part. The detecting unit detects an object around the main body. The control part controls supply amount of the electric power to the power supply part. The control part controls the supply amount of electric power to the power supply part to be reduced compared with a normal state when the detecting unit detects that the object is within a predetermined range of the main body.Type: ApplicationFiled: January 23, 2014Publication date: February 11, 2016Inventors: Koji OTA, Takuya KATAOKA, Manabu MAEDA, Asami OKAMOTO, Yasuhiro SAGOU, Keita SAITOU, Yoshihiko SHIRAISHI, Toshihisa TANIGUCHI

Patent number: 9188357Abstract: A vehicle air conditioner includes a heating heat exchanger, a first temperature adjustment mechanism for adjusting a temperature of air to be blown toward a driver's seat side in a vehicle compartment, and a second temperature adjustment mechanism for adjusting a temperature of air to be blown toward a front-passenger's seat side in the vehicle compartment. In the vehicle air conditioner, the first and second temperature adjustment mechanisms are controlled to perform a one-seat priority mode control such that the temperature of air to be blown toward the front-passenger's seat side is lower than the temperature of air to be blown toward the driver's seat side, when only the driver is in the vehicle compartment and the heating condition is determined as the air conditioning state.Type: GrantFiled: May 19, 2011Date of Patent: November 17, 2015Assignee: DENSO CORPORATIONInventors: Shinichirou Hirai, Yasuhiro Sagou, Manabu Maeda, Takuya Kataoka

Patent number: 8899311Abstract: When there is no occupant in seats other than a driver seat during a foot mode, an air-conditioning controller executes a single seat concentration mode to prevent blowing of warm air to a passenger seat and a backseat by closing foot outlets on a passenger seat side and a backseat side. In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature.Type: GrantFiled: November 15, 2010Date of Patent: December 2, 2014Assignee: Denso CorporationInventors: Haruki Misumi, Takuya Kataoka, Koji Ota, Michio Nishikawa, Shinichirou Hirai, Yoshiaki Suzuki, Akihiro Haraguchi, Katsuji Kuwada, Yasuhiro Sagou

Patent number: 7958740Abstract: A vehicle air-conditioner provided with an inside air-conditioning unit introducing at least one of inside air and outside air, adjusting the state of the introduced air, and blowing it out into the vehicle compartment, where an air-conditioning electronic control device judges if window glass is liable to fog up based on a window glass surface relative humidity near the window glass in the compartment (degree of ease of fogging). When it is judged that the window glass is liable to fog up, the inside air-conditioning unit is controlled to prevent the window glass from fogging up in defrost control, while when it is judged that the window glass is resistant to fogging, the inside air-conditioning unit is controlled to introduce at least inside air into the compartment.Type: GrantFiled: May 31, 2006Date of Patent: June 14, 2011Assignee: Denso CorporationInventors: Shinichiro Hirai, Takuya Kataoka

In this case, in order to maintain an air volume blown from the foot outlet on a driver seat side when the controller changes the mode from the normal foot mode to the single seat concentration mode, the controller sets a blower level to be lower than in the case of the normal foot mode with respect to the same target blown air temperature. Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving.Type: ApplicationFiled: November 15, 2010Publication date: May 19, 2011Applicant: DENSO CORPORATIONInventors: Haruki Misumi, Takuya Kataoka, Koji Ota, Michio Nishikawa, Shinichirou Hirai, Yoshiaki Suzuki, Akihiro Haraguchi, Katsuji Kuwada, Yasuhiro Sagou

Publication number: 20090137989Abstract: A light-permeable member (lens 3) is provided to lead laser beams to an eyeball (2), and a spacer member (refrigerator forming portion 14) is provided to maintain a predetermined space (refrigerator chamber 13) between the light-permeable member (lens 3) and the eyeball (2). The eyeball (2) is cooled by introducing a fluid into the space (refrigerator chamber 13) so as to cool the eyeball (2) while applying the laser beams to the eyeball (2). The laser beams of higher intensity is applied with an occurrence of keratoedema reduced, while at the same time, preventing the complication which otherwise would be caused due to the heat generation of the eyeball (2).Type: ApplicationFiled: May 10, 2006Publication date: May 28, 2009Inventor: Takuya Kataoka
