  • Woodwind instrument having key cups regulated in weight for giving appropriate touch to player
    Patent number: 6015946
    Abstract: A woodwind instrument changes the pitch of sound by selectively closing and opening tone holes by means of a key mechanism, and a player manipulates the key mechanism so as to bring tampons respectively received in key cups into contact with edges defining the tone holes; when a manufacturer shapes the key cups, he forms grooves in the bottom portions of the key cups for regulating the key cup to appropriate weight, and the player feels the key-touch light and comfortable.

  • Key mechanism for a bass range clarinet
    Patent number: 4848206
    Abstract: In the construction of a bass range clarinet having a tubular body with an axial hole for air column vibration and tone holes for sound wave emanation, an additional radial hole is provided in communication with the axial hole to reduce sound wave reflection by an open pad for controlling the condition of each tone hole, thereby assuring generation of a brilliant and clarion tones.

  • Key mechanism for a clarinet
    Patent number: 4793235
    Abstract: In construction of a key mechanism for a clarinet having G# and A key units, release of a G# sound hole is mechanically inhibited by a control unit when a G# key is unexpectedly operated during regular operation on an A key for constant generation of a crisp A sound without any change in traditional finger motion.

  • Coupling unit for a woodwind
    Patent number: 4723470
    Abstract: At assembly of a woodwind such as a clarinet, an annular projection on a joint ring of the first joint abuts against the second ring key on the second joint which is thereupon pushed off the path of movement of the first ring key on the first joint, whereby crash of the ring keys is successfully obviated even at careless assembly.
