Title: Work station equipped with air cleaner
Inventor: INOUE TOSHIAKI
IPC: F24F7/06
Filed: 1987-04-13
Abstract: PURPOSE:To remove dust at a low cost by a method wherein the inside of a case constituting a mainbody is partitioned into the upper and lower parts and filters are installed at openings for at the front of respective parts and clean air passing through the filters is ejected from the lower chamber toward the upper chamber by an air blower. CONSTITUTION:In the inside of a case 10 consisting of a main body two chambers 10a, 10b are defined so as to be located at the upper and lower parts respectively; two chambers are interconnected at the suction side of an air blasting fan 12. At the upper chamber 10a a high density filter 18 covering an opening 14 wholly is installed and at the opening of the lower chamber 22 a prefilter 24 is placed. Indoor air is sucked through the prefilter 24 of the chamber 10b by the fan 12 and then ejected into a work station 8 through the filter 18 as clean air. Since the station 8 can be therefore brought in a clean condition individually by the small fan, piping such as a suction duct, etc., is not necessary and cost can be reduced.

Filed: 1987-04-15
Abstract: PURPOSE:To prevent a malfunction of readout of a magnetic storage disk due to heat expansion by forming a gap part for preventing deformation at the time of heat expansion at an engaging part between a hub and a rotor member. CONSTITUTION:The gap part 14 for preventing deformation at the time of heat expansion is formed at an engaging part 15 between the hub 3 and the rotor member 5. Consequently, the hub 3 and the rotor member 5 are unrestrained from each other at the time of rising the temperature, and hence they are thermally expanded respectively almost in an individual independent state. Therefore, a partial distortion due to a bimetallic action will never happen. Then, a relative thermal distortion is not in existence between the magnetic storage disks 2... and the hub 3 for fitting them, which in general are both made of aluminum, while an actual rotating center of the hub 3 and magnetic storage disks 2... is kept under the state completely coincident with a center C of a shaft part. By this method, no malfunction, such as off-track, etc., will never arise when information read-write operations are performed by a magnetic head 18 on the magnetic storage disks 2..., even at the time of thermal expansion.
