Title: Apparatus for supplying oil of linear compressor
Inventor: PARK JEONG SIK
IPC: F04B17/04
Filed: 1998-11-11
Abstract: PURPOSE: An oil supply apparatus of a linear compressor is provided to prevent the inflow of the impurities contained in oil in a sealed vessel to an oil cylinder with oil. CONSTITUTION: A first oil spring(23A) is stretched and an oil piston(22) moves in the opposite direction of an oil cylinder(21) by the compressing of a second oil spring if the oil cylinder moves in the direction of 'P'. Herein, an oil suction valve(26) is closed, an oil venting valve(27) is opened, and the venting part of the oil cylinder is opened such that the oil filled in the venting space(S2) of the oil cylinder. And the oil filled in a sealed vessel(V) via capillary holes(110) for filtering on an oil suction cover(100) is flowed in and filled in a suction space(S1). The oil filled in the sealed vessel contains impurities generated when welding. The impurities are filtered via the filtering capillary holes and aren't flowed into the oil cylinder. If the oil cylinder moves in the opposite direction of 'P', the pressure of the venting space makes the oil vented to a compressing unit and falls compared to the suction space. Thereby the oil in the suction space is sucked.

Title: Ashing equipment for use of semiconductor fabrication
Inventor: O SEUNG YEONG
IPC: H01L21/306
Filed: 1999-01-13
Abstract: PURPOSE: An ashing apparatus for manufacturing a semiconductor is provided to shorten the time for an ashing process, by cooling a wafer of a high temperature as fast as possible to the extent that an unloaded wafer is not damaged after photoresist is eliminated in a process chamber. CONSTITUTION: An ashing apparatus for manufacturing a semiconductor comprises: a wafer cassette standby chamber in which a wafer cassette loaded with a wafer having photoresist stands by; a process chamber in which the photoresist of the wafer is eliminated; a cooling stage(55) on which the wafer is rested for cooling; a robot arm for loading/unloading the wafer cassette standby chamber, the process chamber and the cooling chamber. The cooling stage further comprises: a upper body(51); a plurality of coolant pipes(52); a lower body(53); and a projection(51c). The upper body has a plurality of concentric ring-type heat emission grooves and an actiniform heat emission groove extended from the center of the concentric circle to the outside. The pluralities of coolant pipes are installed under the upper body. The lower body supports the upper body and the coolant pipes. The projection is projected a predetermined height from the upper surface of the upper body so that the wafer is separated a predetermined distance from the upper surface of the upper body.
