  • Patent number: 9188357
    Abstract: 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.

  • Patent number: 8899311
    Abstract: 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.

  • Patent number: 7958740
    Abstract: 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.

Thus, an electric power consumed by an electric motor of a blower can be reduced, thereby realizing energy saving.

  • Publication number: 20090137989
    Abstract: 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).

  • Patent number: 7461551
    Abstract: A window fog detecting apparatus has an optical type fog detecting sensor for optically detecting fog occurring at a window glass, a humidity sensor for detecting a relative humidity of air at an interior side of the window glass, and a sensor output correcting unit. When a fog occurrence at the window glass is determined based on the output values of the optical type fog detecting sensor, the sensor output correcting unit corrects the relative humidity detected by the humidity sensor based on output values of the optical type fog detecting sensor.
