Title: Method and apparatus for simultaneously reading both sides of optical accumulation disk
Inventor: TAYLOR WILHELM
IPC: G11B7/085
Filed: 1990-11-06
Abstract: PURPOSE: To read both sides of a single disk, whose thickness varies, by positioning the disk and converging first and second converging means at the independent sides of the disk to the center of the converging ranges of each means. CONSTITUTION: Once a base plate is moved to an intrinsic position for the convergence of an upper side optical system 71, upper and lower side optical reading devices 52 and 54 are radially moved against a disk 44 so as to allow the reading and upper and lower side base plates 14 and 16 are pivoted around hinges 22, 24, 26 and 28 for positioning. In other words, each of the base plates 14 and 16 is hinged to one of the edges of the devices 52 and 54, When a motor 18 rotates, master screws 30 and 32 move and slave nuts 34 and 36 move so that the base plates 14 and 16 are pivoted up and down around the hinge by yokes 40 and 42. In other words, by the adjustment of parallel base plates, optical systems 70 and 71 are positioned at the distance equal to the focal length from each surface of the disk 44. Thus, both sides of a single disk, whose thickness varies, are read.

IPC: B29L30/00
Filed: 1996-10-25
Abstract: PROBLEM TO BE SOLVED: To prevent a tire from being broken when it is taken out with a simple structure by a method wherein arcuate segments are moved radially outward about its connecting point with a lower mold by pivotally connecting the upper end part of a parallel link with the respective arcuate segments and its lower end part with the lower mold. SOLUTION: The upper end part of a parallel link 35 is pivotally connected through pins 36 with respective arcuate segments 22 and its lower end part through pins 37 with the outer end part of a lower mold 12. In order to vulcanize a green tire T, a lower, an upper and sector molds 12, 15 and 20 are closed and the parallel link 35 tilts upwards radially inward. In order to discharge a vulcanized tire after the end of a vulcanization, the arcuate segments 22 is lifted by raising the upper mold 15 and translated radially outward about the pins 37 so as to peel off the whole surface of the vulcanized tire from the respective arcuate segments 22.

Title: Hinge for spectacle
Inventor: OTSUKI RYUICHI
IPC: G02C5/22
Filed: 1994-10-28
Abstract: PURPOSE: To impart adequate jerking to opening and closing actions of a hinge without loosening and hardening over a long time and to prevent the dislodgment of screw parts by loosening. CONSTITUTION: One projecting wall 12 of a female member 10 is bored with a through-hole 13 of a diameter nearly equal to the root diameter D of a screw hole 16 of the other projecting wall 15 on the same center line. A projecting piece 21 of a male member 20 to be fitted into a guide hole 11 is bored with a loose fitting hole 22 of a diameter larger than the diameter of the through-hole 13. Further, a broad hollow groove 35 is formed at the leg part 32 of screw parts 30 and an elastic ring 37 is fitted therein. The elastic ring 37 exists in a loose fitting hole 22 of the projecting piece 21. Then, the force to stop loosening after screwing-in is high. This force to stop loosening does not degrade in spite of the long use time. Since the elastic ring 37 does not come into contact with the female member 10, the turning thereof is smooth and does not loosen.  In addition, the turning does not harden and the adequate jerking effect is maintained long. Further, the through-hole 13 and the loose fitting hole 22 are formed of a stepped shape and, therefore, the dislodgment of the screw parts 30 does not arise.

Filed: 1990-11-07
Abstract: PURPOSE:To make it possible to remove a form plane and deliver it to the outside of a machine obtaining workability and safety by removing the form plate from a plate cylinder in such a manner that the form plate is sucked to a sucking par so as to separate the plate form from the plate cylinder and to rotate the plate cylinder in that state and delivering the plate to the outside. CONSTITUTION:An air cylinder 18 is operated into the direction of C in a state that a form plate 34 is sucked to a suction end 7, the suction end 7 is moved in the direction of D, and the form plate 34 is separated from a plate cylinder 32. When the plate cylinder 32 is rotated in a delivery direction, that is, in the direction of E, a sucking outer ring 11 of the suction end 7 rotates in the direction of an arrow F. However, since a suction hole 10 arranged in a part where the sucking outer ring 11 is contacting with the form plate 34 always communicates with the inside of a pipe 8 through passages 12 and 8a, the form plate 34 is kept being sucked to the suction end 7. The form plate 34 is moved on a form plate receiving frame 2 in the left direction being removed from the plate cylinder 32, and the form plate 34 is taken out to the outside. As the sucking force is stable, the work for taking out the form plate can be performed stably and assuredly.
