Abstract: An inlet/outlet pipe extending downward from a bottom face of a body for a ladle is bent at its tip end into an S-shape in an intermediate portion of the pipe, and its tip end is located at a level higher than that of the bent portion. When a negative pressure in the ladle body is increased, a height of range of a molten metal is increased before and after an occurrence of disturbance in the ladle body, so that the negative pressure in the ladle body is made balance with a weight of the molten metal. Thereby, the molten metal is measured and held at a constant volume in the ladle body.

Abstract: A processing unit for executing parallel cumulative absolute difference operations in a first mode, and an inner product operation in a second mode, includes an input bus group for receiving first input data, second input data, and third input data. A plurality of processor elements are coupled to the input bus group, each processor element being coupled to compute a cumulative absolute difference between the first input data and the second input data in the first mode, and to compute and accumulate one term of Booth's algorithm for multiplying the first input data by the third input data in the second mode. An output bus group is coupled to the processor elements, for receiving the terms of Booth's algorithm. An accumulator circuit is coupled to the output bus group, for shifting and adding terms of Booth's algorithm output by the processor elements.

Abstract: An optical head assembly for use with an optical disk apparatus includes a magnetic circuit block having permanent magnets each being elongate in a track traversing direction and a yoke for forming a magnetic circuit which conducts a magnetic field generated by the permanent magnets. The yoke includes a first through hole extending in a focusing direction, magnetic gaps located at opposite sides of the first through hole in the track traversing direction and individually accommodating the permanent magnets, and a second through hole for admitting the light beam issuing in the track traversing direction to guide it to the first through hole. The first through hole and magnetic gaps each has a cross-section relatively long in the track traversing direction. A beam deflector is loosely fitted in the first through hole for deflecting in the focusing direction the light beam which is incident thereto from the second through hole. The beam deflector is supported by a carriage.

Abstract: A recording and/or reproducing apparatus for a cassette mounted, flexible magnetic disk, wherein the apparatus includes a cassette holder which rides upon camming surfaces carried by a slide plate which, when moved relative to the cassette holder, lowers the cassette holder onto a disk drive turntable in a manner such that the end of the holder closest to the magnetic recording/reproducing heads is lowered last whereby the disk is fully chucked by the turntable before being engaged by upper and lower magnetic recording/reproducing heads.
