Abstract: An electronic device which easily offers an optimal operational position taking ergonomics into account without spending time and effort is provided. The electronic device includes a base, a display, an input device, display swing means, and input-device swing means disposed closer to the screen viewing side than the display swing means. The display swing means swingable attaches the display to the base. The input-device swing means swingably attaches the display to the input device. When a tilt angle of the screen of the display increases, a tilt angle of the keyboard increases in accordance with the increase in the tilt angle of the screen.

Abstract: There are provided processes for the preparation of .gamma.-methacryloxypropylsilane compounds which comprise carrying out the reaction of allyl methacrylate with a hydrosilane compound in the presence of a platinum catalyst, while allowing at least one of a hindered phenol compound and an aromatic amine compound to coexist in the reaction system with an alkylamine compound or an amide compound, or with a gas containing molecular oxygen, or with a phenol compound having an aminoalkylene group. By using these processes as provided, gelation of the reaction mixture in the reaction system and during the course of purification thereof by distillation can effectively be avoided, and the desired .gamma.-methacryloxypropylsilane compounds can be obtained in good yield.

Abstract: A method for processing a work, which is running in a direction, by making reciprocal scanning of laser beams and by repeatedly processing substantially parallel processing lines. By determining the scanning velocity vector of the laser beam by operation of the running velocity vector of the work and the relative processing velocity vector to the work, the processing lines are effectively formed.Furthermore, by inclining the work in a manner that the maximum angle made by the work and the laser beam is other than the right angle, the intensity of the laser beam is stabilized.

Abstract: A process for preparing aminopropyl silanes in which an allylamine is reacted with a hydrosilane in the presence of a catalyst comprising (i) metallic rhodium or a rhodium compound and (ii) a basic compound. By the proposed process the corresponding gammaaminopropyl silane can be prepared in a high selectivity and yield within a short period of reaction time.
