Title: Fluid bearing type optical deflector
Inventor: UCHIDA TOSHIYA
IPC: F16C32/04
Filed: 1989-11-16
Abstract: PURPOSE:To constitute the optical deflector of a small inclination of a reflecting surface by adopting the constitution consisting of a dynamic pressure bearing part to a large effective diameter and applying a prepressure to the bearing part in a thrust direction by magnets. CONSTITUTION:A dynamic pressure is generated in a radial bearing 1B and a thrust bearing 1A when a revolving shaft 1 and a mirror 6 are rotated in a prescribed rotating direction at a prescribed rotating speed by the motor driving part. The revolving shaft 1 is then supported without contact is radial ad thrust direction by a sleeve 2 and continues to rotate in the state in which the friction load and friction fluctuation are nearly zero. The spacing in the floating state of the thrust bearing 1A is about 1 mum with respect to the effective diameter of a thrust groove a when the attraction force between the 1st and 2nd thrust magnets 13, 14 is adequately set by adjusting the spacing thereof. The surface inclination of the revolving shaft 1 and the mirror 6 fixed thereto is suppressed to submicronorder. The correct thrust bearing support is thus executed even if the entire part of the optical deflector is placed horizontally or vertically upside down.

IPC: B01D29/62
Filed: 1990-11-01
Abstract: PURPOSE:To minimize outflow of clogged substance into the environment and restore the capability of a main filter by removing the clogged substance in the main filter by means of the back flow from the mesh of the filter, transferring the clogged substance to an auxiliary filter, and storing therein. CONSTITUTION:A circuit is set up among a pump 4, a main filter 6 and an auxiliary filter 7. Usually a mixed fluid is sucked from a suction hole 1 and a substance is separated by the main filter 6 and discharged by a pump 4. When said main filter 6 is clogged with the substance, the circuit is switched over by selector valves 3 and 5, and the substance clogged in the main filter 6 is scattered off directly out of the mesh by the output of the pump 4, transferred to the auxiliary filter 7 and stored therein. As a result, the clogged substance can be taken out in the form of being wrapped in when cleaning or replacing the filter. The outflow of the clogged substance into the environment can be minimized by said arrangement to recover the capability of the main filter.
