Title: Magnetic recording/reproducing apparatus
Inventor: TAKEKADO SHIGERU
IPC: G11B21/21
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To secure the stability of the characteristic of a recording/reproduction signal by restricting fluctuation in float value in a float type and changes in contact state that could cause a head to separate from a disc in a contact system when receiving turbulence. SOLUTION: This magnetic recording/reproducing device has a voltage generation circuit 6 to apply a potential difference between a disc 1 and a head slider 3a and a control circuit 8 which controls the potential difference to regulate the posture of the head slider 3a to the disc 1. When detecting acceleration as caused by turbulence from an acceleration sensor 7, the control circuit 8 controls the potential difference of the voltage generation circuit 6 to restrict fluctuation in a float value in a float system or changes in contact force in a contact system as caused by the turbulence. This can restrain instability of recording and reproducing operations as caused by the turbulence thereby securing stable recording/reproducing characteristics.

Title: Vibration damping device
Inventor: ICHINOTO SEIICHI
IPC: F16F7/10
Filed: 1983-04-11
Abstract: PURPOSE:To cancel cut the vibration force of a columnar member or a beam for effectively damping vibration, by arranging, in the columnar member or the beam in a part other than the fixed ends thereof, a body having a natural frequency substantially equal to the of the columnar member or the beam so that the body may carry out swinging motion. CONSTITUTION:When an axial air-gap motor 11 is driven, a rotary drum 5 rotates so that a molecular pump 24 is operated for introducing, into the rotary drum 5 through a feed pipe 19, gas to be dissociated. The above-mentioned gas is subjected to large centrifugal force and therefore, is dissociated into heavy gas component and light gas component. By the way, a scoop pipe 18 vibrates during the above-mentioned operation, but since a cylindrical body 41 which is attached to the lower end of the pipe 18 vibrates, having 180 deg. phase difference with respect to the vibration in the direction orthogonal to the axis of the pipe 18, the friction force between pivots 42a, 42b and the pipe 18 and as well the intertia force of the cylindrical body 41 which are caused by this phase difference, cancel out the vibration of the pipe 18.
