  • Hinge structure for a console box lid
    Patent number: 8074832
    Abstract: A hinge structure for a lid of an in-vehicle console box includes a storage box having an opening, a lid having a front end and a rear end, and a hinge member having a rotation axis. The hinge member is disposed between the storage box and the lid so the lid rotates around the rotation axis to open and close the opening. A slide mechanism is located between the lid and the hinge member so the lid can move in the directions of the front end and the rear end in relation to the hinge member when opening and closing the lid. A converting mechanism converts a turning force for rotating the lid around the rotation axis to a linear force for sliding the lid in the directions of the front end and rear end so the lid moves in the direction of the rear end when being opened, and in the direction of the front end when being closed.

  • Automatic player musical instrument producing short tones without missing tone and automatic playing system used therein
    Patent number: 7557280
    Abstract: 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.

  • SUPPORTING STRUCTURE FOR ADJUSTABLE AIR GUIDE VANES
    Publication number: 20090137200
    Abstract: 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.

  • Automatic player musical instruments and automatic playing system incorporated therein
    Patent number: 7528309
    Abstract: While an automatic player piano is reenacting a music tune, the automatic player piano sometimes fails to miss a tone or tones in a repetition due to a high-speed key movement; a controller searches a music data file for a series of key events expressing the repetition, and makes the key movements uniform without changing the lapse of time from the last key event before the repetition and the lapse of time to the first key event after the repetition so that the automatic player piano is less liable to miss a tone.

  • Automatic player capable of reproducing stop-and-go key motion and musical instrument using the same
    Patent number: 7473841
    Abstract: A servo controller of an automatic player piano normalizes an actual key position to a value less than a reference value indicative of a target stop on a reference trajectory when the key is found in a region immediately before the target stop and to another value greater than the reference value when the key exceeds the target stop, and adjusts a driving signal to a proper value in such a manner that a solenoid-operated key actuator minimizes the difference between the value or another value and the reference value, whereby the servo controller keeps the key in a narrow region on both sides of the target stop for reproducing stop-and-go key motion.
