Abstract: PURPOSE: A journal foil bearing with a noncorrugated bump foil and a motor with the same are provided to form the bump foil with the small difference of out-of-roundness using the noncorrugated bump foil. CONSTITUTION: A journal foil bearing comprises a holding member(110), a top foil(120), and a bump foil(130). The holding member comprises a cylindrical opening part(101) for receiving a shaft and is extended in one direction. The top foil is received in the cylindrical opening part and is formed along the inner circumference of the holding member. The bump foil without corrugation is arranged between the top foil and the holding member to surround the top foil.

Abstract: PURPOSE: An apparatus for improving starting performance, a cooling machine and a cooling system equipped with the same are provided to use a bypass path and a check valve, thereby quickly completing starting under inlet/outlet pressure conditions for the wide range of cooling machines and systems applied with an air bearing. CONSTITUTION: An apparatus(100) for improving starting performance includes a compressor(130), a turbine(140), a fluid bearing, a bypass path(210), and a check valve(220). The apparatus is connected to a cooling machine. The turbine is connected to the compressor by a flow path. The fluid bearing bears a rotary shaft at the turbine. The bypass path is branched from the inlet of the compressor and is connected to the flow path so that a fluid is directly supplied to the turbine by skipping the compressor when starting the cooling machine. The check valve is placed on the bypass path. The apparatus is equipped with first and second inlets(214,213) and first and second outlets in order to form the bypass path. A first heat exchanger(110) is mounted on the inlet of the compressor. The fluid flows in the first heat exchanger so that heat exchange between the fluid and a coolant is implemented in the first heat exchanger. A second heat exchanger(160) is placed on the flow path with which the compressor and the turbine are connected to each other.

Abstract: PURPOSE: An outer port pressure is maintained evenly regardless of an inner port pressure, thereby improving stability and reliability. CONSTITUTION: A valve body(1) is composed of an air passage(5) and a pressing space(10). A first and second opening(21,22) is formed to the valve body. A first plug(2) is connected to the first opening detachably. A first spring(4) is installed inside of the first plug. A spool(6) is installed with the valve body to open/close the air passage. A bellows assembly(8) is formed with a vent hole to connect the pressing space to outer air.
