Patent number: 6699583Abstract: To provide a lathing method and apparatus capable of realizing lathing of a bar member made of a hard cutting material and lathing a stock made of a hard cutting material by a lathe including an NC automatic lathe, although lathing of the hard cutting material is impossible in a conventional case, a round bar is rotatably held to be fed along the longitudinal direction of the round bar by a guide bush fixed on the main body side of the lathing apparatus, and the round bar is sequentially fed from the guide bush to a machining tool arranged on the main body side, thereby lathing the round bar in a cantilevered state. For this purpose, a round bar having a solid lubricant layer having a predetermined thickness on the outer surface of the round bar in advance, thereby lathing the round bar so as to reduce friction.Type: GrantFiled: March 31, 1999Date of Patent: March 2, 2004Assignees: Kabushiki Kaisha Matsuo Kogyo Sho, Nitto Kogyo Kabushiki KaishaInventor: Makoto Matsuo

Patent number: 5152390Abstract: An automatic chip separating and feeding apparatus capable of permitting chips to be individually separated and transferred at a high speed and with high reliability for charging. A chip transfer controller which includes a projectable stopper pin and a photosensor are arranged between a linear alignment feeder and any one of chip supports of a wheel to control the projecting of said stopper pin and the actuation of the wheel in association with detection by the photosensor to individually separate chips fed by the feeder and transfer them one by one to the chip supports of the wheel by suction.Type: GrantFiled: December 29, 1990Date of Patent: October 6, 1992Assignee: Nitto Kogyo Kabushiki KaishaInventors: Shigeru Kubota, Shoji Kanou, Masahiro Kubo

Patent number: 4953749Abstract: A chip separation and alignment apparatus capable of accurately and readily accomplishing separation and alignment of chips with a simple construction. The apparatus includes a chip separation and alignment section and a chip separation section. The chip separation and alignment section includes a chip cassette formed into a flat rectangular box-like shape, in which are formed a chip storage chamber, a chip alignment hole provided with an upper end opening through which the chip alignment hole is communicated with a lower portion of the chip storage chamber and a lower end opening, and at least one air ejection port arranged near the upper end opening to intermittently eject air therethrough. The chip separation section is arranged at the lower end opening of the chip alignment hole to separate chips one by one and to successively supply the separated chips to a subsequent step.Type: GrantFiled: December 5, 1988Date of Patent: September 4, 1990Assignee: Nitto Kogyo Kabushiki KaishaInventors: Shigeru Kubota, Shoji Kanou, Masahiro Kubo

Patent number: 4670981Abstract: A method of mounting electronic parts on the predetermined positions of a printed circuit board is disclosed which is capable of simultaneously correcting the misregistration of a plurality of electronic parts by one cycle of operations so as to precisely position and mount the electronic parts on the printed circuit board. In the present invention, the misregistration of individual electronic parts with respect to suction tubes of a suction head in an automatic chip-mounting apparatus is corrected at the time when the suction tubes suck up the electronic parts from the cavities of the jig in which the electronic parts are charged to thereby place each of the suction tubes on the predetermined or exact suction position of the electronic parts or align the center of each of the electronic parts with that of the corresponding suction tube.Type: GrantFiled: February 28, 1986Date of Patent: June 9, 1987Assignee: Nitto Kogyo Kabushiki KaishaInventors: Shigeru Kubota, Shoji Kanou, Masahiro Kubo
