  • Patent number: 6332311
    Abstract: The present invention provides a hairiness suppressing device for an automatic winder that can perfectly balloon a spun yarn using a whirling current in a yarn passage. In a hairiness suppressing device (1) comprising a yarn inserting opening (9) that extends and opens in an axial direction of a yarn passage (8) in which a whirling current acts on a spun yarn, a wedge-shaped cover member (29) is provided that can open and close the yarn inserting opening (9). When a swiveling body (26) is swivellably moved to open the cover member (29), the yarn can be introduced into the yarn passage (8) through the yarn inserting opening (9). When the swiveling body (26) is swivellably moved to close the cover member (29), the whirling current in the yarn passage (8) is prevented from leaking from a side of the yarn passage (8).

  • Patent number: 6333233
    Abstract: A method of manufacturing a semiconductor device having a self-aligned contact hole includes a step of forming first gate electrode structures having a high pattern density on a gate insulating film in a first area of a semiconductor substrate and second gate electrode structures having a low pattern density on the gate insulating film in a second area, a step of forming first and second insulating films having different etching characteristics over the semiconductor substrate, a step of anisotropically etching the first and second insulating films in the second area by masking the first area to form side spacers on the second gate electrode structures, a step of forming an interlayer insulating film over the semiconductor substrate, and a step of forming in a self-alignment manner an opening reaching the source/drain region in the first area, by using the second insulating film as an etching stopper. This method allows to reliably form a self-aligned contact hole even if the pattern density is high.
