Abstract

PURPOSE:To eliminate the filtering time of the filtering system to exclude floating dust in a closed vessel by coating the inside surface of the closed vessel with an adhesive material to catch dust floating in the vessel. CONSTITUTION:An inside surface 2 of the closed vessel is coated with an adhe sive material 1 to catch dust floating in the vessel. For example, when the surface is coated with the adhesive 1 of high adhesion in the case of an air current shown by an arrow 3, dust is caught by only contact to the adhesive surface and is neither scattered nor floated again. Thus, dust floating in the vessel is stuck and is not floated again, and all of dust coming into contact with the surface of the vessel is stuck through air drifts.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a sealed disk device, and more particularly to a sealed disk device having a function of removing dust floating inside a sealed container.

[Conventional technology]

Conventionally, floating dust inside this type of closed container is filtered by a filtration filter by circulating the air inside the container using the rotation of a disk.

[Problem to be solved by the invention]

The above-mentioned floating dust in the conventional sealed container depends on air circulation, and it takes a considerable amount of time for the dust to be captured by the filtration filter, and the floating dust can seriously affect disks, heads, etc. Ta. Furthermore, if there are areas within the container where air circulation is not performed properly, the air will stagnate and a large amount of dust will accumulate. This dust has the disadvantage that the air flow is disturbed by the rotation and stopping of the disk, the driving of the head drive unit, etc., and the collected dust becomes floating dust again, which adversely affects the disk head.

[Means to solve the problem]

The method for removing floating dust from a sealed disk device according to the present invention traps dust floating inside the sealed container by applying an adhesive substance to the inner surface of the container.

〔Example〕

FIG. 1 is a sectional view of an embodiment of the present invention. In this embodiment, a highly adhesive adhesive 1 is applied to the inner surface 2 of the sealed container.

FIG. 2 is an example of air flow within a structure.

Arrow 3 indicates air flow. Even in such a case, if a highly adhesive adhesive 1 is applied to the surface, the dust will not adhere to the surface of the adhesive just by contacting it and will not scatter or float again.

〔Effect of the invention〕

As explained above, the present invention applies an adhesive substance to the inner surface of a closed container to prevent dust floating inside from adhering to the container and causing it to float again. This also has the effect of allowing all the dust that comes into contact with the container surface to adhere to it.

Furthermore, the filter filtration method (e) eliminates the filtration time which is a disadvantage of the air circulation type, and has the effect of eliminating floating dust simply by allowing the dust inside the container to come into contact with the surface of the container.
