Abstract: An object of the present invention is to provide an air conditioner for a rail vehicle that is excellent in cleanliness and comfort by cleaning the air conditioner at an appropriate timing without causing discomfort to passengers. An air conditioner for a rail vehicle including a vehicle control system includes: a refrigeration cycle device 3 that can execute a cleaning operation; and an air conditioning control device 4 that controls the refrigeration cycle device, and the air conditioning control device 4 can communicate with the vehicle control system 2 and causes the refrigeration cycle device 3 to execute a cleaning operation on the basis of status information obtained from the vehicle control system 2.

Abstract: Provided is an air conditioning system for a railway vehicle that is of a roof installation type. The air conditioning system includes a heat exchanger through which at least air inside the railway vehicle passes, and an ultraviolet-ray irradiation device. The heat exchanger and the ultraviolet-ray irradiation device are arranged between an upper cover curved in an upwardly protruding shape and a bottom plate. The heat exchanger has an air suction surface arranged so as to be irradiated with ultraviolet rays generated by the ultraviolet-ray irradiation device. A member that does not transmit the ultraviolet rays is arranged on a straight line interconnecting the ultraviolet-ray irradiation device and an interior space of the railway vehicle.

Abstract: A monoclonal antibody to KIR2DS1 or a fragment containing an antigen-binding region thereof has VL having an amino acid sequence of SEQ ID NO: 1 or an amino acid sequence having the same amino acid sequence as the amino acid sequence except that one or several amino acids are conservatively substituted as CDR1, having an amino acid sequence of SEQ ID NO: 2 or an amino acid sequence having the same amino acid sequence as the amino acid sequence except that one or several amino acids are conservatively substituted as CDR2, and having an amino acid sequence of SEQ ID NO: 3 or an amino acid sequence having the same amino acid sequence as the amino acid sequence except that one or several amino acids are conservatively substituted as CDR3; and VH having an amino acid sequence of SEQ ID NO: 4 or SEQ ID NO: 5 or an amino acid sequence having the same amino acid sequence as the amino acid sequence except that one or several amino acids are conservatively substituted as CDR1, having an amino acid sequence of SEQ ID NO

Abstract: Provided is a heat exchanger which includes: a flat pipe as a heat transfer pipe in which refrigerant flows; and multiple fins having openings for inserting the flat pipe and arranged at a predetermined interval in a length direction of the flat pipe. At the flat pipe, multiple linear cutouts used for positioning the multiple fins are formed at the predetermined interval in the length direction of the flat pipe, and at least part of an edge of each opening contacts a corresponding one of the cutouts.
