  • Patent number: 7034295
    Abstract: A photoemission electron microscopy having a light source system for carrying out a high-resolution measurement such as work function distribution measurement or magnetic domain distribution with reliability, and a high-sensitivity measurement method using the photoemission electron microscopy. A photoemission electron microscopy having an excitation light source system in which a specimen is irradiated with irradiation light from a light source uses a vacuum chamber in which the specimen is placed and an objective lens which collects the irradiation light on a specimen surface. The objective lens is accommodated in the vacuum chamber. The light source may be placed outside the vacuum chamber. A condenser lens which makes the irradiation light from the light source generally parallel may be placed between the light source and the vacuum chamber. A transmission window which transmits the irradiation light while the vacuum chamber is sealed may be placed between the condenser lens and the objective lens.

  • Patent number: 6640570
    Abstract: In a vehicle air conditioner, an interior heat exchanger of a heat pump refrigerant cycle is disposed in an air conditioning case to heat and cool air passing therethrough. The air conditioning case has therein a bypass passage through which air flows to a downstream side while bypassing the interior heat exchanger. In a defogging mode, air mainly passing through the bypass passage is blown toward a windshield of the passenger compartment, and air mainly passing through the interior heat exchanger is blown toward a lower side in the passenger compartment. Accordingly, even by setting the heating capacity of the interior heat exchanger at a maximum degree, it can restrict a windshield from being fogged in the defogging mode.

  • Patent number: 6625994
    Abstract: If a refrigerant leaks from an interior heat exchanger, an outside air mode is switched ON, and a first bypass channel is opened to supply air, not having passed through the interior heat exchanger, to a passenger compartment through a defroster opening portion, while also supplying air, having passed through the internal heat exchanger, to the passenger compartment through a foot opening portion. Consequently, air having passed through the first bypass channel and thereby containing a considerable quantity of outside air free from the leaked refrigerant is supplied to the upper side of the passenger compartment, while air having passed through the interior heat exchanger and thereby containing the leaked refrigerant is supplied to the lower side of the passenger compartment, which makes it possible to prevent driver inhalation of the refrigerant.
