Abstract: PURPOSE:To set the stopping position of a hammer shank of a piano sound stopping device, which performs sound stopping by displacing a damper stop rail and stopping the movement of the hammer shank during a string hitting operation, at a desired position during a sound stopping. CONSTITUTION:A base 60 is provided in a projecting manner on a damper stop rail 50 through fixed screws 64 and a shock absorbing material 58, which absorbs the shock during a sound stopping, on the base 60. Moreover, the rail 50 is provided at the damper stopping position of an action mechanism internal section through a supporting shaft 52 in a freely rotatable manner. As a result, the shaft 52 is rotated by an external operation and the sound stopping member, which consists of the base 60 and the material 58, is positioned at either one of the sound stopping positions where the member is abutted to the hammer shank during a string hitting operation or a retracting position where the member is retracted from the sound stopping position. Moreover, the amount of protrusion of the base 60 from the rail 50 is adjustable by the fixed screws 64. Therefore, the stopping position of the hammer shank during a sound stopping is adjustable.

IPC: H04L5/14
Filed: 1981-07-28
Abstract: PURPOSE:To automatically determine the transmission speed, by changing the speed of a transmission time signal at predetermined time intervals and establishing the line with the predetermined procedure. CONSTITUTION:A computer 1 selects the transmission speed by turning on and off a signal 10 with an internal program control.
