Title: Fluid separation membrane made of polyether imide
Inventor: LANGSAM MICHAEL
IPC: B01D71/64
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To improve the fluid separation performance of a fluid separation membrane made of a polymer by using a specified polyether imide prepared by the reaction of 1,5-naphthalene diamide(NAPda) and bisphenol A dianhydride(BP A-DA). SOLUTION: The membrane is formed out of the polyether imide having the repeating unit expressed by the formula. Since the polyether imide having this structure, that is BPA-DA/NAPda, is soluble to an aprotic casting solvent, the formation of the membrane by casting is easy. And, the weight-average mol.wt. (Mw) of the polyether imide is kept between 15,000 and 100,000. The membrane formed out of this polyether imide exhibits a desired fluid transferring property, and the membrane is applied for dehydration, the separation of oxygen and nitrogen, the separation of hydrocarbon. Moreover, the membrane formed from the polyether imide having the NAPda has high oxygen permeability P (O2), that is larger than 0.8.

Title: Whetstone for wafer chamfering and chamfering method for wafer
Inventor: MATSUMOTO MASAYUKI
IPC: B24D7/14
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To obtain a chamfering method in which the service life of a whetstone for wafer chamfering is enhanced, in which the face relative roughness of a chamfered face at a semiconductor wafer is increased and in which the chamfering and working time is shortened. SOLUTION: First, the outer circumference of a silicon wafer W is traversely ground by a coarse abrasive grain part 2 as a face whetstone. A prescribed diameter is set by an outer circumferential grinding operation. Then, the outer circumference of the wafer W is ground by a fine abrasive grain part 23 as a fine whetstone, and a chamfered face is formed. Concretely, a corner part on the surface side at the outer circumference of the wafer is ground by an upper-side inclined sidewall 26, and a corner part on the rear surface at the outer circumference of the wafer is ground by a lower-side inclined sidewall 26. As a result, it is possible to manufacture the wafer W in which the chamfered face in a prescribed shape is formed, and a burden which is applied to the whetstone and the wafer is reduced.  Consequently, the life of the whetstone becomes long, the mean value of the face relative roughness of the chamfered face is reduced, and the efficiency of a chamfering method can be enhanced without lowering the face relative roughness of the chamfered face.

Title: Method for controlling rolling-down of elongator for tube
Inventor: EKOSHI TORU
IPC: B21B17/14
Filed: 1992-12-24
Abstract: PURPOSE:To make thickness at a tube end uniform by correcting a preliminarily set rolling-down control pattern of the rolling reduction roll of an objective rolling-down controlled stand. CONSTITUTION:A hydraulic rolling-down mechanism 1 with which the opening degree of roll is controlled by symmetically operating upper and lower rolls by just equal quantities at the same time to the pass line is provided on a specified stand 2. When tubes 3, 13 are bitten and run out, grooved rolls are controlled by a hydraulic rolling-down mechanism 1 to reduce the wall thickness in tapered shape so as to become thin from the middle part toward the tube end so that the thickening in the tube end part that is generated in a reducing mill (stretch reducer) 6 at the ensuing stage is canceled. Then, based on a distance from the tube end and thickness measured with a hot thickness gage 8 provided on the downstream side of the reducing mill 6, the preliminarily set rolling-down control pattern of the rolling reduction roll of the objective rolling-down controlled stand is corrected. In this way, rolling-down control for thinning the tube end part is executed with high accuracy.
