Abstract: An infrared detecting device is provided. The infrared detecting device includes: a semiconductor substrate; a first layer having a first conductivity type on the semiconductor substrate; a light receiving layer on the first layer; and a second layer having a second conductivity type on the light receiving layer. A part of the first layer, the light receiving layer, and the second layer form a mesa structure. The second layer contains AlzIn1-zSb (0.05<z<0.18). The side surfaces and an upper surface of the mesa structure are covered with the protective layer. A part of an upper surface of the second layer that forms an interface between the second layer and the protective layer has an oxide layer made of a constituent material of the second layer. The oxide layer includes an oxide of Al and has no oxide of Sb.

Abstract: The present invention is a contact lens treatment solution containing the following copolymer A and copolymer B in a ratio of A/B=1000/1 to 2/1 (by weight). According to the present invention, there can be provided a contact lens treatment solution capable of removing dirt having adhered to contact lens surfaces and capable of imparting persisting hydrophilicity to contact lens surfaces, by simple immersion treatment. Copolymer A: a copolymer obtained by copolymerization of a monomer (a) represented by formula (1) and a monomer (b) represented by formula (2), in which the copolymerization ratio of the monomer (a) to the monomer (b), a/b=7/3 to 9/1 (by mol), and having a weight-average molecular weight of 400,000 to 700,000.

Abstract: Provided is an air conditioning system for vehicles, this air conditioning system being configured in such a way that it is possible to perform air conditioning for separate purposes, such as for cooling a driver, this type of air conditioning being extremely efficient in terms of energy, and that even if part of the air conditioning system is installed in a vehicle cabin, it is possible to meet requirements for securing a space in the vehicle cabin. The aforementioned air conditioning system for vehicles comprises a refrigeration circuit provided with a compressor, a condenser, an expansion means, and an evaporator, and is characterized in that the compressor and the condenser are disposed in an in-vehicle area outside the vehicle cabin, and that the expansion means and the evaporator are locally disposed in one or more selected specific regions in the vehicle cabin, preferably in such a way as to be incorporated into units.

Abstract: An air conditioning system for a vehicle passenger compartment comprises a first duct unit including at least one inlet opening and a blower device, and a second duct unit fluidly connected to the first duct unit. The second duct unit includes an evaporator and a heater core, and further includes a damper mechanism and a plurality of outlet openings. An evaporator is disposed forward of the heater core in the second duct unit and forms a part of an air-conditioning circuit. The heater core is disposed rearward of the evaporator and partially covers the second duct unit. The damper mechanism is disposed rearward of the evaporator and controls the amount of air passing through the evaporator and the heater core and introduced to the outlet openings.The resulting air conditioning system is compact in size and lightweight while simultaneously providing superior air conditioning performance.
