Abstract: Conductive balls are transferred from a pallet onto an array of conductive pads on a semiconductor chip by means of a transfer apparatus; the transfer apparatus includes a pallet formed with an array of recesses same in pattern as the array of conductive pads, a movable head formed with an array of vacuum holes and a driving mechanism for moving the head from an idle position onto the pallet and from the pallet to the semiconductor chip; when the head is moved to the pallet, the vacuum holes are connected to the recesses so as to confine the conductive balls in the narrow spaces; the vacuum is developed; then the conductive balls are traveled through the closed spaces to the vacuum holes; even if the conductive balls have been charged, the conductive balls are never attracted to the adjacent balls, and are surely captured by the vacuum holes.

Abstract: A zipper tape is provided which can freely be used regardless of whether the zipper tape is made from a polypropylene-based resin or a polyethylene-based resin and also on which letters can be printed or any color can be given thereto. A method of producing the zipper tape with high productivity by means of extruding male strips and female strips in rows in a batch is provided. The zipper tape with the mating section formed thereon has a three-layered structure. The male strips and female strip for forming a mating section together are extruded from a miscellaneous extrusion molding machine onto a surface of the thermally fused film for forming a mating section in rows in the state where adjoining male and female strips form pairs respectively and are thermally fused and bonded to the base tape.

Abstract: Material to be treated such as garbage is charged into a first rotary kiln 14 to be mainly dehydrated and charged into a second rotary kiln 18 to be carbonized. The first rotary kiln 14 has a first nozzle pipe 11 therein for spouting a first high temperature gas and the second rotary kiln 18 has a second nozzle pipe 15 for spouting a second high temperature gas, mainly high temperature superheated steam with a temperature higher than a temperature of the first high temperature gas. The carbonized material is discharged outside after a temperature thereof is lowered to prevent spontaneous combustion in an atmosphere. Thereby, it is able to provide an apparatus for thermal treatment using superheated steam which can be built relatively small and by which treatment time can be shortened, and further, the final carbonized material can be used as charcoal.

Abstract: An endoscope ocular portion fitted with a microscope gripping mechanism 9 is adopted where a microscope gripping mechanism 10 has; a microscope gripping portion 12 for gripping a microscope ocular portion 11a of a medical microscope 11, an endoscope securing portion 14 secured to an endoscope ocular portion 13a, and a linkage portion 16 linking the microscope gripping portion 12 and endoscope securing portion 14, and positioning and securing the endoscope ocular portion 13a and the microscope ocular portion 11a on the same virtual plane 15 and at approximately the same spacing W as the pupil distance of an observer. According to this endoscope ocular portion fitted with a microscope gripping mechanism 9, observation of both the medical microscope and the endoscope at the same time without the observer significantly moving their head or body, is possible at low cost.

Abstract: An apparatus for lining up micro-balls in accordance with the present invention includes: ball carrying pallets having a plurality of pits for holding the micro-balls, respectively, on its surface, a pallet holder for holding the ball carrying pallets, a lining-up container defining a sealed chamber in association with the pallet holder hermetically fitted thereto, a storing tank for storing liquid carrier in which micro-balls are dispersed, and applying/collecting device for communicating the storing tank with the lining-up container via a passage to supply the micro-balls together with the liquid carrier from the storing tank to the sealed chamber and return the surplus micro-balls together with the liquid carrier from the sealed chamber to the storing tank.

Abstract: A circular hole cutting device (1) for making a circular hole in an object comprises a bit holder (3) which can be attached to a drive shaft of an electric power tool in such a way that the bit holder (3) with a bit (2) attached to a far end of the bit holder (3) rotates together with the drive shaft on a common axis, a cover (4) which is fitted to the bit holder (3) relatively rotatably about its axis, and a radial rod (5) attached to the cover (4) such that the amount of projection of the radial rod (5) in a direction intersecting the bit (2) can be varied.
