摘要： A silencing apparatus is provided for pianos having an electronic sound source as well as the conventional acoustic sound mechanism. The silencing apparatus includes a plurality of arms, a stop rail bridging ends of the arms and a positioning mechanism. When acoustic sound is to be silenced, a wire is pulled by means of an operating lever, thereby pivoting an actuating lever which is connected to one of the arms. This causes the stop rail to pivot to the stop position at which the stop rail abuts against and thereby stops motion of the hammer shanks which move in response to key depressions. The stop rail and the arms thereon define open spaces for accommodating for the presence of the other components, such as damper units, inside the piano. Thus, the silencing apparatus of the present invention travels over a greater range of motion without interfering with the operation of other components inside the piano.

摘要： A damper unit for a piano is provided in which the position of a hammer stop rail for contacting the hammer shanks before the hammers strike the strings can be changed from an inoperative retracted position to a stop position with a relatively small drive force and the hammer stop rail is firmly and reliably positioned at the stop position. Stop rail support arms for supporting the hammer stop rail are connected, via linkage mechanisms composed of links and lever arms, to a rotary shaft. By pulling a wire that is connected to the rotary shaft, the rotary shaft is rotated, such that the hammer stop rail can be positioned, via the linkages, at the stop position and the retracted position, in which the hammer stop rail does not contact the hammer shanks. As compared with the conventional damper unit, the position of the hammer stop rail can be changed with a relatively small drive force. Moreover, the hammer stop rail is thus fixedly positioned at the stop position, thereby reliably dampening the hammer striking sound. The linkage mechanisms may be replaced with a cam mechanism that contacts the stop rail support arms for changing the position of the hammer stop rail.

摘要： In a step of spinning a molten mesophase pitch in a process for manufacturing a pitch-type carbon fiber, the pitch is allowed to pass through an orifice and to be contracted once, is then expanded in an introduction port with a diameter greater than that of the orifice, and is then allowed to pass through an outlet pore formed at a collecting portion to spin the pitch. The pitch-type carbon fiber has a high elastic modulus in tension and high compressive strength.
