IPC: G11B7/24
Filed: 1994-12-26
Abstract: PURPOSE: To provide an optical recording and reproducing method and device capable of attaining high densification of recording and high speed access by suppressing flawing of an optical recording medium accompanying contact and sliding of a floating optical head with the optical recording medium. CONSTITUTION: Data is recorded or reproduced on a recording layer of a track part 4 of the optical recording medium 1 consisting of a glass substrate having the track part 4 on the light incident side surface and the recording layer provided on the light incident side surface of the glass substrate by the floating optical head 2 equipped with a floating slider which keeps a gap against the surface of the optical recording medium 1 by an airflow accompanying rotation of the optical recording medium 1.

Title: Sound stopping mechanism of piano
Inventor: YAMASHITA MITSUO
IPC: G10C3/16
Filed: 1994-12-26
Abstract: PURPOSE: To provide a sound stopping mechanism of a piano by which generation of a chord hitting sound can be reliably stopped. CONSTITUTION: A stopper 41 is slidably supported in the vertical direction with a support body 31 fixed to a master leaf 4 of a piano, and is energized in the upward direction by a tension spring 47. The stopper 41 can operate a wire 48 by a lever arranged on the lower side of a shelf board. When the wire 48 is pulled by operating the lever, the stopper 41 slides in the downward direction against energizing force of the tension spring 47, and is positioned in a checking position. At this time, since a hammer felt of a hammer starting inertial motion comes into contact with the stopper 41 before reaching a chord, hitting of the chrod is checked.  On the other hand, when the wire 48 is loosened by operating the lever, the stopper 41 slides in the upward direction by energizing force of the tension spring 47, and is positioned in an allowable position, and allows hitting of the chord by the hammer.
