摘要:
To provide an alcohol compound containing fewer impurities at a high yield by conducting the following steps: a hydroboration process in which a reaction mixture is obtained by reacting in a solvent a compound represented by formula (C) and a boron agent selected from a group of diborane and borane complexes; and an oxidation process in which the pH of the reaction mixture is set at 0.5 to 4, which is conducted after treating the reaction mixture with hydrogen peroxide. In the formula, A1 to A6 are each independently a hydrogen atom, methyl group or ethyl group, and X is an oxygen atom, sulfur atom, methylene group or ethylene group.

A method of producing a porous sheet, which comprises the steps consisting of preparing a dispersion having ultra-high-molecular-weight polyethylene particles dispersed in a solvent, applying the dispersion onto a film to form a coating layer thereon, sintering the coating layer, and removing the solvent contained in the coating layer.
摘要:
The method for measuring speed is performed by dividing the time sequence image data A into long and narrow frames (step 401). Next, the framed images and the time sequence image data B produced by the line scan camera B are correlated to obtain a moving time (step 402). Next, a moving time of each framed image and a corresponding moving distance are obtained to compute a moving speed (step 403). Next, scale of a specific shape pattern and the like is corrected using the moving speed obtained to match the scales in the two image sequences A and B to obtain a similarity degree (step 404). Next, a threshold value is applied to the similarity degree to recognize the specific shape pattern, thereby recognizing that the images are produced by a moving vehicle.

摘要:
In a heat exchanger in which a number of V-shaped convex portions are arranged in parallel at a surface of a fin, one of a pair of inclined convex portions forming a V-shape is arranged to be inclined to a plus side by an angle a relative to a circulation direction of a gas at a first plane of a fin, the other is arranged to be inclined to a minus side by an angle b, and both of them are arranged by asymmetric angles in a left and right direction, and at a second plane opposed to the first plane, the angles which are asymmetric in the left and right direction are made to be reverse to those of the first plane relative to the circulation direction of the gas.
