Abstract: A balloon for a catheter includes an inflatable portion, a distal end connecting portion, and a proximal end connecting portion. The balloon for the catheter also includes an inner side thick film portion and a thin film portion having differing thicknesses from each other. The thickness of the inner side thick film portion is greater than the thickness of the thin film portion. An inner surface at the inner side thick film portion protrudes further toward an inner side than an inner surface at the thin film portion. An outer surface at the inner side thick film portion does not protrude further to an outer side in the radial direction than an outer surface at the thin film portion.

Abstract: This scroll compressor comprises: a shaft that is capable of rotating about an axis; a motor that rotatably drives the shaft; a compressor body that is driven by the rotation of the shaft; a housing that covers the motor and the compressor body and that has a bottom surface facing the motor from the axial direction; an intake port that guides a refrigerant into the housing; and heat-dissipating fins that are formed on the bottom surface, that extend in the direction in which the refrigerant flows, and that are divided in the flow direction.

Abstract: A motor includes a motor body having a rotor that is rotatable around an axis and a stator that surrounds the rotor; a casing that has a cylinder portion and a an inverter box, the cylinder portion forming a cylindrical shape extending in an axial direction and surrounding the motor body, internally having a cooling water channel that extends in a C shape in a circumferential direction, and being used for allowing cooling water to flow, the inverter box overhanging on both sides of the cylinder portion in a tangential direction on an outer peripheral side of the cooling water channel in the cylinder portion; and an inverter that is housed in the inverter box and has a switching element disposed on a surface of the cylinder portion facing radially outward in the inverter box.
