    Abstract: A reciprocating compressor of the disclosure includes a cylinder, a piston, a space for compressing gas, a discharge port for discharging the compressed gas from the space, a discharge valve, and a supplying port for supplying liquid that is different in kind from the gas. The cylinder has an axis extending in a direction of gravity. The piston is disposed to be reciprocable along the axis inside the cylinder. The space is constituted above the piston by being surrounded by the piston and an inner peripheral surface of the cylinder. The inner peripheral surface of the cylinder includes a straight portion and a throttle portion. The throttle portion is constituted such that an inner diameter of the cylinder decreases toward the discharge valve.

    Abstract: A vehicle seat heater is provided in a vehicle seat. This vehicle seat heater includes a first heat generator, second heat generator, and controller. The first heat generator is disposed in a first area of the vehicle seat supporting an occupant. The second heat generator is disposed in a second area not being in contact with the occupant or being less pressed by the occupant than the first area is. The controller controls current application to the first heat generator in a manner such that a heating temperature zone of the first heat generator is a direct heat transfer temperature zone close to a body temperature of the occupant, and also controls current application to the second heat generator in a manner such that a heating temperature zone of the second heat generator is a radiation heat transfer temperature zone.
