摘要： An automatic player piano is equipped with an electronic supporting system, which makes a player learn an optimum pedal stroke to a half pedal region; while the player is practicing a music tune on the piano, the electronic supporting system monitors the damper pedal; when the player starts to depress the damper pedal, the electronic supporting system exerts an assisting force on the damper pedal so as to make the player feel the damper pedal light; when the damper pedal reaches an entrance of the half pedal region, the electronic supporting system removes the assisting force from the damper pedal so that the player feels the damper pedal heavy, whereby the player learns the pedal stroke to the half pedal region through the change of load borne by the player.

摘要： An electronic proof system is provided in association with an automatic player piano; while a human player is practicing a music tune on the acoustic piano, the electronic proof system monitors the pedals of piano to see whether or not the player brings the pedals to target pedal positions; if the current pedal position is spaced from the target pedal position, the electronic proof system gives rise to fine vibrations of the pedal, and makes the player notice the pedal staying at incorrect pedal position through the tactile impression.

摘要： An automatic player piano is a combination between an acoustic piano and an automatic playing system, and a grand piano and an upright piano are used as the acoustic piano; the grand piano has action units prompter than action units of the upright piano so that a half-stroke recorded through the grand piano is not reproducible by the upright piano; the automatic playing system causes the hammers to rotate toward the strings without any escape thereby compensating the poor promptness with the short keystroke of the keys until the rotation of hammers.

摘要： A structure for supporting an air guide vane in a supply opening for air conditioning prevents abrupt changes of load resistance to rotation of the air guide van and provides a good operational feel when rotating the air guide vane. A supporting member of the air guide vane is an olefin-based thermoplastic elastomer having a hardness of between Shore A80 and Shore D60. The degree of mold transferability of olefin-based thermoplastic elastomer is characteristically lower than that of other thermoplastic elastomers. By virtue of molding an olefin-based thermoplastic elastomer microscopic concavities and convexities are formed on the surface of the supporting member. The rotation shaft of the air guide vane is supported by multiple point contacts with the inner surface respective through-holes.

摘要： A music data modifier receives pieces of original music data from a master hybrid piano, and partially modifies the pieces of original music data to pieces of modified music data for a slave hybrid piano; each piece of original music data contains a series of values of a piece of motion data expressing continuous motion of the associated key, a series of values of a piece of time data expressing each expressing a time to obtain the associated value of the motion data and a piece of identification code expressing the key number assigned to the key; even if the music data modifier changes the piece of identification data from the key number to another key number, the piece of motion data still expresses the continuous motion of the key so that the slave hybrid piano exactly reproduce the key motion.

摘要： In order to define movement of a particular key to be automatically operated, first-order trajectory data are generated, on the basis of performance information, which are indicative of variation over time of position, velocity and acceleration components of the particular key. Jerk component related to the movement of the particular key is calculated on the basis of the acceleration component in the first-order trajectory data, and second-order trajectory data are generated by modifying the first-order trajectory data with the calculated jerk component. Then, a drive device for driving the particular key is servo-controlled on the basis of the second-order trajectory data. In this way, nonconstant acceleration (or constant jerk) control, rather than constant acceleration control, can be performed to control driving of the key during a successive key depression, so as to allow the successively-depressed key to operate with an increased smoothness.

摘要： An automatic player piano has a feedback control loop for each of the black/white keys; the controller firstly determines a reference trajectory, i.e., a target key position varied with time for each key to be moved in the play-back, and calculates a target key velocity, and compares a true key position reported from a key sensor and a true key velocity calculated from the true key position with the target key position and target key velocity for optimizing the duty ratio of the driving signal; the positional difference and the velocity difference are independently multiplied by a positional gain and a velocity gain so as to determine the optimum duty ratio; since the ratio of the velocity gain to the positional gain is 1 to 3, the key travels along the reference trajectory without oscillation and overshoot.
