Title: Base material of plastic optical fiber, manufacture therefor, and wiring drawing method for plastic optical fiber
Inventor: FUJII TAKASHI
IPC: G02B6/00
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To shorten the master drop time and to manufacture a favorable plastic optical fiber at good yield by making the softening temperature of a master material part lower than the softening temperature of a middle part of a base material to be spun. SOLUTION: In a base material 11A, a tip master material part 10A whose softening temperature is lower is softened at a temperature lower than that of a middle part 14 forming a product. Therefore, it enters the state immediately before the master drop in a short time, so that a softened area of the middle part side forming a product is narrowed. Accordingly, the shape of the base material 11A immediately before the master drop is near the steady state, a part 15 to be discarded until it reaches a steady state is small, and when wire drawing is started, the fiber can be manufactured in a short time.  A concrete means for lowering the softening temperature of the master material part 10A of the base material 11A tip is to spray a solvent for dissolving the material of a plastic optical fiber, or to impregnate the tip of the base material 11A with a solvent by repeating dipping and drying, so that the tip is swollen. Thus, it is possible to obtain the base material 11A having the tip whose softening temperature is lower than that of the middle part.

Abstract: PROBLEM TO BE SOLVED: To make it possible to accurately measure without deforming or damaging the leads by rotatably mounting a roller member for urging the lead to a contact, and moving the member toward the end of the lead as the lead falls. SOLUTION: An IC 9 having bent one of leads 10 is placed on the contact 4 of an IC socket 3. Then, the wedge part 11 fallen by a cylinder 8 gives a repelling force of a spring 7 to the lead 10 to a roller 1 via pressing part 2b and movable part 2a, and moves the part 2a. Thus, the roller 1 falls from the place where it is initially brought into contact with the bent lead 10 of the right side to retain it while rolling on the bent lead 10 until it is brought into contact with the contact 4. Then, the bent lead 10 is corrected by the roller 1 at the stopped position of the roller 1, and brought into contact with the contact 4 in the same state as the normal state of the lead 10 of the left side.

Abstract: PURPOSE:To eliminate the restriction on operator's movement around the optical axis for observation. CONSTITUTION:The peak of the intensity to receive the ultrasonic waves transmitted from the signal transmission section 9B of an ultrasonic position sensor 9 moves between signal reception sections 9A disposed in plural pieces in the upper part of a mirror body 4 when a head mount display 8 moves. As a result, a rotating angle alpha deg. is detected. Luminous fluxes 17, 18 for L and R of a liquid crystal plate 2 are changed to the positions respectively moved by alpha deg. in order to move the luminous flux transmission regions by alpha deg. around the optical axis X for observation in accordance with the rotating angle alpha deg. detected by the ultrasonic position sensor 9. These luminous fluxes are thus corrected to the parallax generated when the operator observes the operation part P from the imaging position of the head mount display 8. An image pickup device 3 is rotationally moved to the position rotated by alpha deg. by a motor in order to move the direction of the observed image by alpha deg. around the optical axis X for observation simultaneously therewith, by which the image is corrected to the image when the operator observes the operation part P from the position of the head mount display 8 after the movement.
