  • Patent number: 10792195
    Abstract: A method includes distributing a powder onto a first sheet, periodically closing a distribution port by a first opening-closing portion, and periodically closing the distribution port by a second opening-closing portion in the same cycle period as that of the first opening-closing portion and at a timing later than that of the first opening-closing portion. The method also includes moving the second opening-closing portion such that it extends from an upstream-side edge of the first opening-closing portion toward an upstream side of a movement direction, during a time period during which the upstream-side edge of the first opening-closing portion overlaps the distribution port. Further, the method includes setting a difference between timings at which the first and second opening-closing portion overlap the distribution port, respectively.

  • Publication number: 20200190702
    Abstract: Provided is a polyurethane elastic fiber wherein surface treating agents do not bleed even after lengthy storage, thereby preventing contamination of packing material, and which exhibits stable friction performance independent of storage duration, making the fiber suitable for a stable gathered member with low occurrence of core slip-back. This polyurethane elastic fiber is a multifilament polyurethane elastic fiber and is characterized by having, in the multifilament cross section, a void part demarcated by the constituent individual filaments being in contact with one another and by having a cross-sectional void part area ratio of 15% to 60% as calculated according to the formula (cross-sectional void part area ratio [%])=100×(area of the void part)/(total cross-sectional area), where the total cross-sectional area is the sum of the area of the void part and the cross-sectional areas of all individual filaments that constitute the multifilament.

  • Publication number: 20200111464
    Abstract: The disclosure provides a keyboard device and an electronic musical instrument. The keyboard device includes: a plurality of keys 60 arranged in a left-right direction (scale direction); a base member 50 supporting the keys 60; a vibration transmission member 70 being in contact with the base member 50 across an arrangement region of the keys 60 in the left-right direction; and a vibrator 72 fixed to the vibration transmission member 70 and vibrating based on pressing of the key 60. Therefore, the vibration of the vibrator 72 is transmitted to each of the keys 60 (base member 50) arranged on the left and right via the vibration transmission member 70. As the vibration transmission member 70 has higher rigidity than the base member 50 made of resin, the vibration of the vibrator 72 is easily transmitted in the left-right direction through the vibration transmission member 70.
