Title: Vessel sealing mechanism and cap used for the mechanism
Inventor: YOSHIHARA TETSUO
IPC: B65D51/28
Filed: 2002-08-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide a vessel sealing mechanism for preventing degradation of the quality of raw materials or the like by using a plug which can be directly and easily fitted to vessels to separately store raw materials to be mixed with each other, and reliably discharging the raw materials housed in a housing chamber, and a cap used for the mechanism.  <P>SOLUTION: A cap (1) comprises a plug part (4), a sealing plug (5), and a sleeve (6). The plug part has a top plate (11) to seal an opening part (3) of a vessel (2), a side wall (12) protruded from the top plate along the axis (X) with an inner peripheral surface adaptable to an outer peripheral surface of the opening part, and a cylindrical wall (15) protruded from the top plate within the side wall to form a housing chamber (14) having an opening (13) in a lower end face. The sealing plug has the outside diameter (D1) larger than the outside diameter (D2) of the cylindrical wall, and seals the opening in the housing chamber. The sleeve is freely fitted to the cylindrical wall, and detaches the sealing plug from the cylindrical wall to open the opening when the vessel is relatively moved to the cap. A flange part (16) of an outer circumference of the sleeve has the outside diameter larger than the inside diameter (D3) of the opening part, and is flexible so as to pass the opening part by the deformation of the inside diameter in a non-return manner.  <P>COPYRIGHT: (C)2004,JPO

Title: Substrate processing device
Inventor: SUZAKI KENICHI
IPC: H01L21/68
Filed: 2002-08-20
Abstract: <P>PROBLEM TO BE SOLVED: To prevent generation of particle caused by scraping between a boat holding groove and a wafer in a substrate processing device.  <P>SOLUTION: A CVD device has a processing chamber 14 for processing a plurality of wafers 1 at once, a boat 21 for holding each of the wafers 1 by means of a holding surface 26 of a plurality of holding grooves 25 each, and a heater unit 30 which overheats a group of wafers 1 of the processing chamber 14. In the device, an R chamfer 27 of a curvature radius of 1mm or more is formed in an edge of the holding surface 26. Since an edge of the holding surface does not scrape against a protected surface of the wafer even if the wafer warps, a film applied to the wafer is prevented from peeling, and generation of particle can be prevented.  <P>COPYRIGHT: (C)2004,JPO

Title: Ejector cycle
Inventor: TAKEUCHI HIROTSUGU
IPC: F25B40/00
Filed: 2002-08-22
Abstract: <P>PROBLEM TO BE SOLVED: To keep COP of an ejector cycle high.  <P>SOLUTION: A variable throttle 450 is mounted before an ejector 400, and the pressure of a refrigerant is reduced in two stages by the variable throttle 450 and a nozzle 410 by fully opening the variable throttle 450 when a high pressure-side refrigerant pressure is higher than an approximate critical pressure, and reducing the opening of the throttle in comparison with the full-opened condition when the high pressure-side refrigerant pressure is lower than the approximate critical pressure. Whereby a pressure reducing degree (degree of restriction) can be prevented from being reduced to more than necessary in an uncritical zone where the thermal load is small, even when a nozzle diameter is set to be optimum in the super critical zone. Whereby the COP of the ejector cycle can be kept high by a simple means in both of high heat load and low heat load.  <P>COPYRIGHT: (C)2003,JPO
