    摘要: A breather filter for a hard disk drive is attached to a hole provided in the cover of the disk drive. The breather filter has a first sheet that forms a diffusing tube at a position corresponding to the hole provided in the cover of the disk drive. The filter also has a second sheet forming an opening at a position corresponding to the diffusing tube of the first sheet. A third sheet of the filter has an adsorbent layer at a position corresponding to the opening in the second sheet. Finally, a fourth sheet, including a filter layer, covers the adsorbent layer of the third sheet and is stacked with each of the sheets.

    摘要: A drawing surface adjusting mechanism for use with a scanning pattern drawing apparatus capable of not only moving a drawing board in a vertical direction but also tilting it, whereby the chance of bringing the drawing surface within the depth of focus of a scanning lens is increased even if the drawing surface has waviness or other flaws within the width of a single storke of scanning. The drawing surface adjusting mechanism of the invention includes a drawing board for supporting a workpiece that is to be scanned with a scanning optical system by means of a unidirectionally tracing light beam, transport means for allowing the drawing board and the scanning optical system to slide relative to each other in a direction that crosses the direction of beam tracing at right angles, a first and a second drive mechanism which are spaced apart in the tracing direction and which move one side of the drawing board in a direction parallel to the direction of the beam, tilt control means for inclining the drawing board with respect to the transport means by making the drive amount of the first drive means different from that of the second drive means, and translation control means for effecting a translational movement of the drawing board with respect to the transport means by making the drive amount of the first drive means equal to that of the second drive means.
