Title: Magnetic recording and reproducing device
Inventor: MIHASHI DAISUKE
IPC: G11B33/14
Filed: 1989-06-12
Abstract: PURPOSE:To prevent discharge from a magnetic sheet to a magnetic head by elastically supporting a projecting electric good conductor guiding discharge owing to a charged charge to the magnetic sheet in such a way that it approaches to and saves from a position adjacent to the magnetic head in the window part of a jacket holder interlocking the loading and unloading of a magnetic sheet pack. CONSTITUTION:Gildered spring materials 10 and 11 which are prevented from interfering the shift of the magnetic head 5 in the window part 4b of the jacket holder 4 are elastically supported and parts in positions nearest to the magnetic head 5 are bent, whereby they come to be projecting parts 10a and 11a which are made to approach to the magnetic sheet 1. When the charged charge is to execute discharge to the magnetic sheet 1 by exceeding insulating resistance, discharge is guided by the projecting parts 10a and 11a and discharge is executed to the projecting parts 10a and 11a. Thus, discharge for the magnetic head 5 is prevented and the occurrence of noise also can be prevented without the destruction of a coil.

IPC: F16C33/76
Filed: 1989-06-12
Abstract: PURPOSE:To suppress friction and to reduce drive power by inseting a disc-like partitioning board set on a spindle in a groove orthogonal to a shaft having a filler therein. CONSTITUTION:On the atmospheric side of opening 9a at part of vessel 9 having insulation gas therein, a housing having a through hole 10 at its center is hermetically set. In a groove 10f formed vertical to the axial direction on the inner circumferential face of a hermetical condition retaining member 10e, a filler 12 such as grease is poured. Generally insulation gas with several values of atmospheric pressure is filled in the vessel 9, and a partitioning board 16 formed of thin plate is pressed against the atomospheric side of the groove 10f in response to gas pressure. At this time, the filler 12 is normally between the board 16 and the member 10e, whereby no sticking of both members prevents gas leakage. The friction generated at the time of rotation of a spindle 15 being only the viscous resistance of filler as well as the contact resistance of bearing part, the drive power is reduced.
