Concentric grooves 52 are formed and connected to the air inlet ports 50. when a semiconductor wafer is conveyed on the rotary stage 12, sucking though the air inlet ports 50 is started. The air between the lower surface of the semiconductor wafer 14 and the rotary stage is exhausted through the grooves 52. Thus the sucking and holding of the semiconductor wafer 14 are ensured. The surface is inspected with a polarized laser beam S. A gap 70A is kept at an negative pressure state. Therefore, abrasive particles yielded in the gap 70A are exhausted to the outside of the apparatus together with the air and do not remain in the gap.

IPC: B01D53/94
Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To lower soot ignition temp. and to enable the combustion of particulates PM at the temp. of exhaust gas by using an exhaust gas purifying catalyst composed of a specific spinnel type composite oxide.

Abstract: PURPOSE:To reduce a pressure loss due to passing air through a heat exchanger when temperature regulation becomes unnecessary such as a time except working time, when temperature regulation does not require accuracy or the like, by providing the heat exchanger movably between a first position and a second position. CONSTITUTION:When the temperature should be regulated accurately, a fixing frame 14, fixing the heat exchanger 9, is contacted closely with a stopper 23 so that the whole of circulating air, passing through a return duct 8, passes through the heat exchanger 9.

Filed: 1997-04-01
Abstract: PROBLEM TO BE SOLVED: To provide a method for facilitating the treatment of a spillage heavy oil or crude oil in the form of a viscous solid containing a treatment inhibiting substance such as seawater. SOLUTION: Titanium oxide particles in at least a ratio of 0.2 to 1 based on spillage heavy oil expressed in terms of weight ratio are added and mixed with the spillage heavy oil recovered in a metallic barrel, etc., and the heavy oil is specifically adsorbed from the spillage oil, containing seawater, etc., and converted into the form of a viscous solid on an adsorbent (S1). Water is then added to the metallic barrel to suspend the resultant mixture in water (S2). The formed suspension is filtered through a filter of a coarse mesh to remove treatment inhibiting substances of a larger size than that of the adsorbent containing the heavy oil sticking thereto, e.g. seaweed, sand or stone (S3). The resultant filtrate is recovered (S4).  The recovered filtrate is then passed through a high-performance filter (a fine mesh so as to enable the recovery of the adsorbent) to recover the adsorbent containing the heavy oil sticking thereto. Thereby, the seawater, etc., together with the water for suspending, are removed (S5).
