Title: Coating method of optical fiber
Inventor: KIMURA TAKAO
IPC: C03C25/10
Filed: 1981-10-20
Abstract: PURPOSE:To obtain an optical fiber having a uniform outside diameter, by adjusting the feed speed of a thermoplastic resin pipe to control the film thickness of a thermoplastic resin to be applied to the thermoplastic resin pipe. CONSTITUTION:A base material 1 is slowly introduced into a fiber drawing furnace 3 by a base material feeding apparatus 2, and heating in the fiber drawing furnace 3 and spun into an optical fiber 5. The outside diameter of the optical fiber 5 is read by an outside diameter measuring apparatus 4, and optical fiber 5 is then passed through a pipe 6 consisting of a thermoplastic resin, which is slowly inserted in a heater 8 by a pipe feeding apparatus 7. In preparing the pipe 6 continuously, the resin extruded through an extruder 13 is passed through a crosshead 14 to form a pipe around the optical fiber 5, and then the pipe 6 is inserted in the heater 8. The pipe 6 is heated locally by the heater 8 and applied to the optical fiber 8. The outside diameter of the coated optical fiber 9 is read by an outside diameter measuring apparatus 10, and the optical fiber 9 is then wound by a winder 12.

Title: Fixation of pile and base seat
Inventor: ISHII MOTOYOSHI
IPC: E02D27/12
Filed: 1984-08-10
Abstract: PURPOSE:To obtain a given grout strength by a method in which a flexible film bag is set in piles driven through the base seat of the bottom ground under water, and a grout is injected into the bag and hardened to fix the pile and the base seat. CONSTITUTION:A pile 2 is penetrated through a cylinder 3 into the ground under water, and a grout injection hose 8 is connected to an inlet 4 for grout. When a grout 9 is injected into the inlet 4, the flexible bag 5 is expanded by the injecting pressure of grout to close the aperture between the cylinder 3 and the pile 2. The hose 8 is then removed out, and the grout 9 is hardened to fix the pile 2 and the base seat 1. Since the grout can be injected under a dry condition without water, the grouting work can be made exactly and the same grout strength as in the case of onshore grouting work can be obtained.

Abstract: PURPOSE: To stop a magnetic head at a start position and end position securely by providing a switch at the start position or end position of the head and by closing the switch with an operating piece provided to the head in one body.  
     CONSTITUTION: At the start position and end position on chassis 40, end detecting microswitches 56 and 57 are provided and when head 9 is moved to the start position, operating piece 55 closes end detecting switch 56 to stop 9 with its output. Thus, head 9 is securely stopped at the prescribed position of the outmost circumference. When head 9 is moved to the end position, on the other hand, end detecting switch 57 is closed to stop head 9 at the prescribed position of the inmost circumference with the output of it. Consequently, the head can securely be positioned at the start position or end position even if the stored number of tracks of the microcomputer when the power is turned off is erased or if a track shift is caused due to vibration impact.
