Title: Production of optical fiber preform
Inventor: HIGASHIMOTO MASAKAZU
IPC: G02B6/00
Filed: 1985-09-09
Abstract: PURPOSE:To readily carry out etching of an interface between a core member and clad member at a low cost with a high accuracy, by introducing a fluorine compound and oxygen into a gap between the core member and the clad member before melting and integrating the members by a rod-in-tube method and heating the members. CONSTITUTION:A core member 1 is inserted into a pipelike clad member 2 and a mixture of a fluorine compound, e.g. SF6, with oxygen at a suitable ratio is introduced into a gap between both members 1 and 2, which are then heated at 1,300-1,800 deg.C from the outside of the clad member 2 by using an oxyhydrogen flame 3, etc. Thereby, the outer surface of the core member 1 and the inner surface of the clad member are etched to form a smooth and clean surface. The introduction of the fluorine compound and oxygen is then stopped and the clad member 2 is heated by the oxyhydrogen flame 3 from the outside while evacuating the interior of the members to melt and integrate the core member 1 with the clad member 2. Thereby, the aimed base material for optical fibers is obtained. As a result, the amount of etching can be controlled by the heating temperature.

Title: Waste water treating device
Inventor: YOSHIDA TERUHISA
IPC: B01D61/14
Filed: 1990-07-27
Abstract: PURPOSE:To remove the sludge stuck to the surfaces of ultrafilter membranes by the flow in a pressurized aeration tank by immersing these membranes into the aeration tank, permeating purified water through the inside of the membranes by the pressure in the pressurized aeration tank and draining this water as treated water. CONSTITUTION:The circulating flow in the aeration tank 5 is risen in an inside cylinder 8 by withdrawing the liquid mixture on the outer side of the inside cylinder by a circulating pump 10 and ejecting the same from a nozzle 7 of a diffuser in the bottom of the aeration tank, by which the flow falling on the outside of the inside cylinder is occurred. The pressurized air from a compressor 6 is mixed with the circulating water and the air is sheared at the time of ejecting the water from the nozzle 7, by which fine bubbles are generated and the water is aerated. The circulating pump 10 withdraws the liquid from the pressurized aeration tank 5 and maintains this water under the same pressure and, therefore, there is no need for such a pressurizing pump which is heretofore used for ultrafiltration. The pump of the pressure as low as to correspond to the pressure drop of the nozzle and piping is thus usable.

Title: Torque limit clutch
Inventor: DEBITSUDO JIYON FUOOCHIYUN
IPC: F16D43/208
Filed: 1988-08-12
Abstract: PURPOSE: To surely keep torque transmission elements outside engagement thus preventing friction and vibration by making the torque transmission elements movable so as to release the torque transmission engagement due to the movement of an energization member against the energizing force of an energizing means. CONSTITUTION: When torque exceeds a predetermined value, a ball 18 rolls out of a torque transmission recess 16 and a force is applies to the left direction against the energizing force of a spring 21 to move a energization member 19 to a non-engagement position. The tangent of an angle α1 in this position is, however, smaller than the friction coefficient between the ball 18 and the energization member 19. Therefore, ball is held between the energization member 19 and an inner periphery 34 of an aperture 17, thus being kept in the non- engagement position. As a consequence, friction and vibration can be prevented since the ball 18 and the torque transmission recess 16 can be maintained outside engagement after clutch releasing.
