Abstract: A front imaging portion captures the front side of a vehicle. A rear imaging portion captures the interior or the rear side of the vehicle. A casing houses the front imaging portion and the rear imaging portion. A heat sink is located between the front imaging portion and the rear imaging portion in the casing to radiate heat inside the casing. A fixing portion is located on the outer surface of the casing and between a first end and a second end of the heat sink and separated from the heat sink to fix the casing to the vehicle. An intake is located adjacent to the fixing portion at the first end to be open toward the heat sink. An outlet is located adjacent to the fixing portion at the second end to be open toward the heat sink while facing the intake with the fixing portion interposed therebetween.

Abstract: A multiroom air conditioning apparatus includes an outdoor side unit having a compressor and an outdoor heat exchanger, and a plurality of room units having an indoor heat exchanger. A high-pressure gas pipe and a low-pressure gas pipe, connected to the compressor, are branched so that a high-side branch pipe and a low-side branch pipe are connected to the outdoor heat exchanger via outside valves. A liquid pipe through which a refrigerant passes from the high-pressure gas pipe is connected to the outdoor heat exchanger, and branched to provide liquid pipes. The indoor heat exchanger is connected to the branched liquid pipes via expansion device and to the high-side branch pipe and the low-side branch pipe via inside valves. By controlling the outside and inside valves, a selected room unit or units can be cooled or heated.

Abstract: In a low reflection type photomask (hard mask) having a tantalum masking film provided, through or without an intermediary low reflection layer, on a transparent substrate and further having a low reflection layer provided on the tantalum layer, use is made of a composite layer containing tantalum oxide and tantalum nitride as the low reflection layer. The etching speed of the composite layer is faster than that of the tantalum oxide layer conventionally used as low reflection layer, being substantially equal to that of the tantalum film, and there is very little lowering of the dimensional precision of the photomask obtained due to the difference in etching speeds. Further, dry etching is applicable for the above multilayer masking film containing the composite layer and the masking tantalum film, and there is little lowering of the dimensional precision even by overetching.
