  • Patent number: 7674968
    Abstract: An automatic player musical instrument is a combination of an acoustic piano and an electric system, which serves as an automatic playing system and an electronic proof system, and a controller of the electric system has an information processing capability; when a user instructs the electric system to check performance on the keyboard, a subroutine program for electronic proof starts to run; while the user is fingering a music tune, the controller monitors the keys with key sensors to see whether or not the user correctly plays the music tune; when the user mistakenly depresses a key instead of another key, the controller gives rise to vibrations of the mistakenly de-pressed key so as to give a notice of incorrect fingering to the user.

  • Publication number: 20090304545
    Abstract: A lead-free solder alloy exhibiting good performance in impact resistance and vibration resistance. Also provided are a solder ball using such a lead-free solder alloy, and an electronic member having a solder bump using such a lead-free alloy. Specifically, the lead-free solder alloy consists of 1.0 to 2.0% by mass of Ag, 0.3 to 1.0% by mass of Cu, 0.005 to 0.1% by mass of Ni and the balance including Sn and unavoidable impurities. In an Sn—Ag—Cu based solder joint portion on a Cu electrode, a Cu3Sn intermetallic compound layer is formed directly on the Cu electrode, and then a Cu6Sn5 intermetallic compound layer is formed thereon. A Cu atomic site in the Cu6Sn5 intermetallic compound layer is replaced by Ni having a smaller atomic radius than Cu to thereby reduce strain in the Cu6Sn5 intermetallic compound layer, thus enabling impact resistance and vibration resistance to be improved therein.

  • Publication number: 20090013856
    Abstract: While a player is fingering a music tune on a piano, an electronic assistant system monitors the keys to see whether or not the player starts to produce tones through a particular playing technique such as repetition; when the electronic assistant system finds particular key movements unique to the particular playing technique in an early stage, the electronic assistant system decides that the player intends to produce the tone through the particular playing technique, and forces the key to travel on a reference key trajectory in the later stage, whereby the player learns the particular playing technique.
