Title: Molding equipment for diameter-widened port section of synthetic-resin tube body
Inventor: HATSUTORI GOROU
IPC: B29C57/08
Filed: 1983-07-29
Abstract: PURPOSE:To mold the internal form of a tube body accurately to predetermined size by constituting a molding equipment for the diameter-widened port section of the synthetic-resin tube body in such a manner that a stepped section is formed on a border between a front die and an intermediate split die and the diameter of the front end of the intermediate split die is made smaller than that of the rear end of the front die. CONSTITUTION:A stepped section F is formed on a border between a front die 11 and an intermediate split die 13, and a tube body 1 intrudes into an indentation on the intermediate split die 13 side generated by the stepped section F while it fast stickes to a taper 11a in the front die 11 firmly extending over a wide range. Since airtight properties are ensured among the tube body 1 and the front die 11 and a rear die 13, an intake effectively functions when air is sucked through intake paths 14-17, and the tube body 1 can be molded accurately to a predetermined inner-diameter shape. The intake is stopped while water is sprinkled over the tube body 1 to solidify the tube body, and the diameter of the intermediate split die 13 is reduced and the tube body 1 is pulled out.

Title: Device for adjusting attachment position of square noze straight tool in precision lathe
Inventor: KAWANABE YUU
IPC: B23B29/04
Filed: 1983-07-29
Abstract: PURPOSE:To set a square nose straight tool in parallel with a surface to be machined, by optically detecting the reflecting light of a laser beam which is irradiated onto a mirror surface obtained by a slight trial cut, so that an angular deflection of the tip of the tool with respect to the reference line is converted into an electrical signal so that the angle of the tool is adjusted. CONSTITUTION:After cutting a workpiece 12 with a square nose straight tool 52 being slightly contacted to a surface of the workpiece to be machined, a laser beam is irradiated onto the thus obtained cut mirror-surface 66, and the reflected light thereof is received by an image sensor at a light-sensitive point thereon. Therefore, the shift amount from the reference point is delivered, as a detection signal, to a control means 80 by which this detection signal is converted into an operational output for an actuator. Therefore, the attaching angle of the tool is optimumly adjusted and set to make the tip of the tool 52 parallel with the surface of the workpiece 12 to be machined by rotatingly adjusting a tool holder 54. Accordingly, tool exchange operation may be simply made to enhance the efficiency of working, thereby a highly accurate mirror-surface machining may be realized.
