Abstract: The present invention provides a fiber manufacturing method suitable for reducing the variation in outer diameter. The fiber manufacturing method of an embodiment of the present invention includes: discharging a softened linear body 1 through a nozzle 10; and winding the linear body 1 so that the linear body 1 passes through a cooling portion 20 supplied with a cooling fluid 50, thereby obtaining a fiber 5. The cooling portion 20 has a filter 40 configured to rectify the cooling fluid 50. The cooling fluid 50 in the cooling portion 20 has a temperature that is substantially constant in a moving direction of the linear body 1. According to the fiber manufacturing method of the embodiment, an index M determined by the following equation (I) is 1.52 or less.

Abstract: A lens barrel in which an air flow path that causes an external space and an internal space to communicate is formed includes an aperture unit disposed in the internal space and configured to rotate a plurality of vane members within a predetermined range to form a predetermined opening, an optical unit disposed in the internal space and located on an object side with respect to the aperture unit, and a through-hole formed in the aperture unit and communicating with the internal space. When at least one of the optical unit and the aperture unit moves in an optical axis direction, the lens barrel discharges, through the air flow path and the through-hole, air in the internal space and static electricity charged in the plurality of vane members included in the air in the internal space.

Abstract: An assistive music playing apparatus plays a music piece with musically acceptable notes even when the player inputs musically unacceptable notes. The apparatus provides a chord progression pattern, and comprises a note conversion device. A chord progression pattern defines a series of chords, which are presented one after another in time for a music progression. As the player plays music, inputting potentially unacceptable notes, the inputted notes will be converted to musically acceptable notes with reference to the currently presented chord in the chord progression. The note conversion rules are prepared different for a melody note range, a chord note range and a bass note range. Overlap of converted notes are avoided. Depending on the conditions of the player's note input, i.e.
