Abstract: PURPOSE:To To allow the tight adhesion of a fitting part to the uterine cervic- vaginal parts of different shapes and sizes by forming at least a part of the fitting part by using a thermodeformable shape memory material to meet the shape of the uterine cervic-vaginal part. CONSTITUTION:The fitting part 2 is formed by using the shape memory material which is so worked as to be thermally softened and deformed when heated and to cure while maintaining the final shape when cooled. The temp. at which this material begins to soften, i.e., shape restoration temp., is set at the temp. slightly higher than the body temp.; for example, 38 to 45 deg.C. The bore of the fitting part 2 is formed slightly smaller than the outside diameter of, for example, the uterine cervic-vaginal part 6. The fitting part 2 is heated up to the shape restoration temp. to soften. While the shape of the fitting part 2 is so changed as to fit to the uterine cervic-vaginal part 6, the fitting part is fitted to the outer peripheral surface of the uterine cervic-vaginal part 6. The fitting part 2, thereafter, adheres tightly to the outer peripheral surface of the uterine cervic-vaginal part 6 on falling of the temp. The endoscope can be inserted into the vagina while the airtightness or watertightness in the vagina is maintained.

Title: Semiconductor device manufacturing method
Inventor: BYO HIDETO
IPC: H01L21/302
Filed: 1996-12-10
Abstract: PROBLEM TO BE SOLVED: To avoid particles produced from moisture in the air by feeding an inert gas from a second inert gas line in each of steps of carrying a wafer in and out. SOLUTION: A front door C is opened to insert a wafer from a conveying hole B into a reaction chamber A, unavoidably together with the outside air involved thereinto. But, in this step, an inert gas is flowing in the chamber A from an inert gas line L32 connected to a pressure gage line L3 to purge the line L3 with the inert gas and hold the gas pressure in the line higher than that in the chamber A and hence the outside air involved into the chamber A never penetrates into the line L3. This avoids particles produced from the moisture in the air and hence the production yield can be improved.
