A polishing method and a polishing film are provided for automatically performing multi-stage batch polishing on an end surface of a workpiece. An end surface of a workpiece and a polishing plate are moved relative to each other while bringing the end surface of the workpiece into contact with a polishing film of the polishing plate. The end surface is moved in a circular motion with a diameter 2 R relative to the polishing film; the center of the circular motion is moved linearly by a distance S on the polishing film; the polishing film is provided with first, second, and third polishing surfaces; and the polishing film is further provided with cleaning surfaces between the polishing surfaces so that the range of the distance S in which one rotation in the circular motion crosses over different polishing surfaces is reduced, or does not cross over different polishing surfaces.

An optical connector cleaning tool includes a holder, cleaner, and cap. The holder includes, a cylindrical slider, a cylindrical body which is rotatable and movable in the axial direction with respect to the slider, and a slider return spring which biases the body forward to return the slider to the initial position. The slider has a pair of elastic pieces having guide projections. In the outer circumferential surface of the body, spiral grooves with which the guide projections engage are formed within the angular range of 360&#xb0;. When the slider moves forward, the body rotates by the cam action of the guide projections and spiral grooves. The cleaner includes, a cleaning thread accommodated in a rotary pod, a supply reel, a take-up reel, and a cleaning pin, and is connected to the body.

Nozzle openings each including a straight duct portion and a tapered portion are situated at an upstream position of an air flow with respect to the straight duct portion. The nozzle openings are formed in a nozzle plate such that the nozzle openings are arranged in grid, and airborne microorganisms passing through the nozzle plate can be effectively collected to form colonies. A degree of cleanness is measured by counting the colonies visually.

This electrostatic filter dust collector has a dust collecting section which is assembled by using a mini-plate type filter member having a small width of the fold thereof and a short distance between the adjacent ridge portions thereof. Since a plurality of insulating spacers are inserted at suitable intervals into the filter member from the upstream and downstream sides thereof, the percentage of the contacting area of the spacers with respect to the filter member is low, and the percentage of the dust collecting area thereof is high. Electrodes are provided on the upstream and downstream ridge portions of the filter member, and a high voltage is applied between these electrodes, so that a uniform and stable electric field is generated on the filter member as a whole. This enables a high dust collecting efficiency to be obtained.
