Title: Production of preform for optical fiber
Inventor: MIYA TETSUO
IPC: G02B6/00
Filed: 1979-02-06
Abstract: PURPOSE:To obtain a preform useful in production of an optical fiber with little transmission loss by preburning a glass tube while raising or reducing the press. of a gas fed into the tube to hold the tube diameter constant. CONSTITUTION:Glass tube 3 supported by chucks 4 is rotated with rotary connector 7 and heated to the softening temp. of tube 3 or above with moving heat source 5. At this time, the tube diameter is measured in tube diameter measuring section  6. Since the smallest tube diameter has been set in exhaust vol. control section 11,  when the diameter measured in section 6 exceeds the set value, magnet valve 9 is  opened to smoothly exhaust a gas flowing through tube 3. On the other hand, when  the diameter is smaller than the set value, valve 9 is closed to restrict the outlet of  the gas in tube 3 only to the gap of nozzle valve 10, thereby expanding the heated  portion of tube 3. By performing this action in the longitudinal direction of tube 3  together with movement of source 5, tube 3 can be shaped to the set value.

Abstract: PURPOSE:To prevent the generation of angle-down even in the case a curvature wire in the endoscope device is extended by a repeated load. CONSTITUTION:When the curvature operating knob 23 of an operating part 4 of an endoscope 1 is rotated and operated backward or forward and curvature angle data is inputted to a central processor 35, the necessary output value of a tension sensor 20 corresponding to curvature angle data is set from the relation of tension and a curvature angle stored in a storage circuit 36, and a motor 21 is driven through a motor driving circuit 38. Thus, for instance, when a curvature part 8 being in a linear state is raised or lowered gradually, and an output value from the tension sensor 20 coincides with the necessary output value, driving of the motor 21 is stopped and the curvature part 8 is held at a prescribed curvature angle, therefore, angle-down caused by the elongation of operating wires 19a, 19b is not generated, and the curvature can be controlled exactly.
