Abstract: A heat generating apparatus having a housing assembly in which a working chamber including a heat generating region for heat generation and a fluid storing region for storing a viscous fluid, and a heat receiving chamber for receiving heat from the heat generating region are formed. The heat generating apparatus also having a rotor element mounted on a drive shaft to be rotated within the working chamber to apply a shearing action to the viscous fluid within the heat generating region. The viscous fluid generates heat when the shearing action is applied thereto so that the heat is transmitted to a heat exchanging liquid flowing through the heat receiving chamber. The heat generating region and fluid storing region communicating through an aperture formed in a partition wall formed in the working chamber, and the aperture having a gas-phase portion, a liquid-phase portion and a liquid supply portion.
Abstract: A child safety seat can be used as an auxiliary seat in an automobile and a stroller. The child safety seat has front and rear caster arms which are rotatably provided in a seat structure. The front and rear caster arms selectively extend downward from and retract above the lowermost portion of the seat structure. The child safety seat can be attached to the automobile seat when the front and rear caster arms retract.
Abstract: A compressor includes a housing body and a drive shaft rotatably supported in the housing body. A swash plate is mounted on the swash shaft. Cylinder bores are defined in the housing body. Pistons are operably coupled to the swash plate and are disposed in the cylinder bores. The swash plate converts a rotation of the swash shaft to a reciprocating movement of the pistons along an inner surface of the cylinder bores. Each piston compresses gas supplied from a suction chamber to the associated cylinder bore and discharges the compressed gas to a discharge chamber. Deformation of the inner surface of each cylinder bore is reduced by utilizing pressure of the gas compressed in the cylinder bore.
Abstract: An improved piston guiding mechanism for use in piston a type compressor is disclosed. The compressor includes a housing. A cylinder block having a bore is accommodated in the housing. A piston reciprocates within the cylinder bore. A refrigerant gas containing lubricant oil is sucked into the cylinder bore from outside, is compressed within the cylinder bore, and is discharged out of the compressor in accordance with reciprocating motion of the piston. A hollow section extends radially from the central portion to the peripheral surface of the piston, and opens to the peripheral surface. The hollow section moves between the interior of the housing and the cylinder bore in accordance with the reciprocating motion of the piston, and transfers the lubricant oil in the refrigerant gas from inside of the housing to the cylinder bore.
