Abstract:
A method and apparatus of inspecting a sample, in which the sample is inspected under a plurality of inspection conditions, and inspection data obtained by inspecting the sample under each of the plurality of inspection conditions and position information on the sample of the inspection date in correspondence with the respective inspection conditions, are stored. The inspection data for each of the plurality of inspection conditions is against each other by the use of the position information on the sample to determine a position to be inspected in detail, and an image of the sample at a position to be inspected in detail is obtained. The obtained image is classified, the inspection condition of the sample by the use of information of classification of the image is determined.
Abstract:
To improve a performance of a semiconductor device having a capacitance element. An MIM type capacitance element, an electrode of which is formed with comb-shaped metal patterns composed of the wirings, is formed over a semiconductor substrate. A conductor pattern, which is a dummy gate pattern for preventing dishing in a CMP process, and an active region, which is a dummy active region, are disposed below the capacitance element, and these are coupled to shielding metal patterns composed of the wirings and then connected to a fixed potential. Then, the conductor pattern and the active region are disposed so as not to overlap the comb-shaped metal patterns in the wirings in a planar manner.
Abstract:
Provided are a tripod constant velocity joint, and a method and a device for assembling the joint. The opening of a through-hole formed in an inner member of the tripod constant velocity joint has formed therein a tapered, reduced diameter section having a diameter tapered from the opening toward the inside. A first annular groove is formed in the side wall of a driving power transmission shaft, and a clip serving as an engaging member is engaged with the first annular groove. A second annular groove is formed in the inner wall of the through-hole in the inner member. In inserting the driving power transmission shaft through the through-hole in the inner member, the tapered, reduced diameter section guides the shaft in such a manner that the clip is contracted toward the bottom surface of the first annular groove. The clip expands and contracts due to the elasticity thereof when the positions of the first annular groove and the second annular groove coincide with each other.

Abstract:
Polyurethane elastomer foams can be prepared by mixing an isocyanate-terminated prepolymer obtained by reaction of a polyol with 3,3′-dimethylbiphenyl-4,4′-diisocyanate, with a foaming agent comprising a mixture of water, a low-molecular weight glycol having a molecular weight of 48-200, and a high-molecular weight glycol having a number average molecular weight Mn of 1000-3000 under stirring to conduct foaming reaction. The polyurethane elastomer foams so produced can have a high durability, particularly under a high load, even though a low-cost, easy-to-handle diisocyanate compound is used.

Abstract:
An information processing apparatus has a pointing device for designating a position of an arbitrary point with respect to a reference point O, and a processor of the information processing apparatus detects a position of the point designated by the pointing device with respect to the reference point O at every unit of time, and calculates an operation vector AB respectively regarding a point A and a point B detected before and after as a starting point and an ending point. The calculated operation vector AB is orthogonally-projected onto a strait line vertical to a vector OA respectively regarding the reference point O and the point A as a starting point and an ending point. Information processing is performed on the basis of a component vector thus obtained from the operation vector AB.
