Abstract:
PROBLEM TO BE SOLVED: To provide a wire saw having simple construction for cutting a workpiece with a wire line of the wire saw and then pulling up the cut workpiece from the wire line without giving adverse effect on the section of the workpiece. SOLUTION: The wire saw comprises a cutting wire wound around a plurality of rollers to form the wire line, the cutting wire being reciprocatively driven in the axial direction to feed the workpiece to be cut to the wire line while supplying slurry thereto, and to cut the workpiece at a plurality of positions where they are arranged side by side in the axial direction, at the same time. After cutting the workpiece, it controls the wire to pull up the workpiece from the wire line while traveling at a speed of 2 m/min or less. COPYRIGHT: (C)2009,JPO&INPIT

PROBLEM TO BE SOLVED: To prevent vibration of a feed screw shaft in a driving mechanism having a constitution to connect a driving source to one end of the feed screw shaft, rotatably support the other end, and move various kinds of sliding bodies connected to a feed nut screwed to the feed screw shaft. SOLUTION: In this driving mechanism, a driving part having the driving source connected to the feed screw shaft 24 and the feed nut screwed to the feed screw shaft 24 and connected to an action element via a sliding body is provided, and the action element is moved by being driven by the driving part. Inner rings 700 and 710 of ball bearings 70 and 71 for supporting the feed screw shaft 24 are fixed to an outer periphery of a free end part of the feed screw shaft 24. In an inner periphery of a cylinder part 26a for storing the ball bearings 70 and 71 in a terminal supporting part 26, outer ring elastic bodies 77 and 78 for slidably supporting outer rings 701 and 711 of the ball bearings 70 and 71 in an axial center direction of the feed screw shaft 24 and for absorbing vibration of the feed screw shaft 24, are disposed.

Abstract:
PROBLEM TO BE SOLVED: To suppress the generation of a chipping upon cutting a work as much as possible and facilitate washing after taking out a chip component. SOLUTION: The work 1 is pasted onto an ultraviolet ray curing type adhesive agent layer 4 applied on a glass plate 3 having an adhesive power under a condition that ultraviolet beams are not irradiated, while an underlying adhesive 5 is interposed between the glass plate 3 and the ultraviolet ray curing type adhesive agent layer 4, and the work 1 is cut on a hard glass plate 3 into the shape of a lattice. However, the cutting is limited up to a depth of the glass plate 3 via the ultraviolet ray curing type adhesive agent layer 4. After the cutting, ultraviolet ray is irradiated by an ultraviolet ray irradiating means 14 to eliminate the adhesive power of the ultraviolet ray curing type adhesive agent layer 4 and, thereafter, the chip component 2 is taken out by a vacuum attraction nozzle 15.

Abstract:
PURPOSE:To prevent an ingot member such as silicon from being damaged and to improve working efficiency by definitely positioning a supplying mechanism by a supporting means against a mounting base for a cutting device in mounting the above member on the supplying mechanism and cutting it. CONSTITUTION:A supplying mechanism 2 mounting an ingot member W is moved on rails 72 through a carrying truck 13, and is mounted on a mounting base 3 which has been raised or lowered by the lifting device 68 of a supporting base to fit their dovetails 67 each other. In the next stage, the ingot member W is approached to a cutting edge 7a composed of the row of wires fixed on a cutting device 5 by means of the lifting device 68, and is cut after its position has been adjusted by the feeding mechanism 22. The cut ingot member W is moved on the carrying truck 13 again as it has been mounted on the supplying mechanism 2, and is carried to a fix position to device into each wafer. Thus the wafer can be efficiently cut without its damage.
