Title: Manufacture of fiber
Inventor: ETOGARUTO MUTSUSHIERUKUNAUTSU
IPC: C03B37/06
Filed: 1982-11-08
Abstract: In the production of fibers by blast drawing in which primary filaments are produced from a liquid stream, reduced to fibers and drawn on passing through a draw nozzle by drawing gas streams flowing substantially parallel to the primary filaments, the improvement which comprises surrounding the drawing gas streams over at least part of their length and inside the draw nozzle in the direction of flow by parallel boundary gas streams having at most the same flow velocity as the drawing gas streams. Advantageously the parallel boundary gas streams are formed by that part of a circular flow produced on both sides of the drawing gas stream which is in contact with the drawing gas stream, the flow velocity of the parallel boundary gas streams amounts to between about 60 and 80% of the velocity of the drawing gas streams, the drawing gas streams having a velocity of from about 360 to 500 m/s, the volume flow of the parallel boundary gas streams amounting to between about 20 and 60% of the volume flow of the inlet stream, the drawing gas streams and the parallel boundary gas streams being driven by a pressure gradient generated by power jets in the draw nozzle. A corresponding novel draw nozzle is provided. The inner walls of the nozzle do not undergo the erosive/abrasive wear characteristic of other draw nozzles.

Title: Magnetic guide device for unattended vehicle
Inventor: WATANABE HISATSUGU
IPC: G05D1/02
Filed: 1987-08-04
Abstract: PURPOSE:To accurately guide an unattended vehicle by fixing the output of a right magnetic detecting element to a prescribed value in case of a left-turn command from a branch command part and fixing that of a left magnetic detecting element to the prescribed value in case of a right-turn command. CONSTITUTION:A right and left magnetic detecting elements 13 detect the extent of deviation of a vehicle body from the center line of a magnetic tape 12 as an analog quantity of field intensity. When the unattended vehicle reaches a branch point and turns to the right, a branch command part 21 detects a striker ST for branch to fix the output of the right detecting element to a prescribed voltage value. Then, a deviation signal generating circuit 14 outputs an analog voltage corresponding to the difference between the output voltage of the right detecting element and the fixed prescribed voltage value to a control part 16. Since the right detecting element is scarcely affected by the magnetic field generated in the left part of the center line of the tape 12 at this time, the unattended vehicle is run along the right end of the tape 12 and is naturally branched to the right in the branch position.

A solenoid valve 10 is opened by the signal of the detector 14, then the cooling water flows in the mirror 6 to cool the mirror. The cooling water does not flow to the mirror through which the laser light is not transmitted and therefore the generation of dew condensation on account of the cooling on the mirror surface down to the dew point or below is prevented.
