    摘要: The invention provides a method and an apparatus of making a hole in a printed circuit board, which improve the quality of a hole shape and the processing speed. In accordance with the invention, a control apparatus controls a laser oscillator and a galvano mirrors so as to form a hole while gradually reducing a pulse width in each step with respect to one hole. As a result of this, no insulating material is left on the bottom portion of the hole, and it is possible to make a hole having an intended shape, particularly, having a desired diameter of the hole bottom.

    摘要: In a method of drilling a printed circuit board according to the present invention, an entry feed rate at which a drill is fed into the printed circuit boards during the initial stage of drilling is made slightly smaller than a drilling feed rate at which the drill is fed while it is drilling a hole through the printed circuit boards, so as to enhance the accuracy at which holes are located. One drilling operation includes a plurality of drilling feeds of the drill, and pulled-out positions of the drill which are reached by the drill between adjacent drilling feed rate are set within a range in which the pressure of a pressure foot is effective. This can prevent the stacked printed circuit boards from shifting and increase the accuracy at which the holes are located.

    摘要: An adjustable beam size illumination optical apparatus includes a beam size adjusting optical system which includes groups of cylindrical array lenses disposed correspondingly to the long and short axis directions respectively and having variable intervals among the lenses, and a group of cylindrical telescope lenses disposed correspondingly to one of the long and short axis directions and having variable intervals among the lenses, and adjusts parallel light from a light source in size in accordance with the two axis directions orthogonal to each other. The lens interval of one of the cylindrical array lens groups and the cylindrical telescope lens group is changed to adjust a beam size on a projection surface in accordance with the long axis direction or the short axis direction. Thus, it is possible to adjust the beam size in accordance with the long axis direction and the short axis direction individually, and it is possible to make irradiation with the beam with uniform intensity.

    摘要: A process for producing an optically active compound based on the hydrolysis of an alkenyl ester compound or the cleavage of an alkenyl ether compound. The process uses neither an acidic compound nor a basic compound, and reactants can be reacted in a high concentration. It does not necessitate a buffer, nutrient, etc. unlike enzymatic reactions or reactions using a microorganism. It is a simple process which attains a satisfactory production efficiency. The process, which is for producing an optically active carboxylic acid or optically active alcohol represented by the general formula (VI): (wherein R1, R2, and R3 are different groups; and A represents methylene, carbonyl, or a single bond), is characterized by causing water to act on an alkenyl ester or alkenyl ether represented by the general formula (I): (wherein R4, R5, and R6 each represents hydrogen, alkyl, etc.) in the presence of a specific transition metal complex having an optically active ligand.
