Title: Magnetic disk apparatus
Inventor: NAKAMURA GENTARO
IPC: G11B33/14
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent a lubricant of a bearing from entering the internal space of a magnetic disk apparatus, by providing a mechanism for isolating the carriage bearing and the internal space of the magnetic disk apparatus. SOLUTION: A cover 1 is tightly fixed to a carriage shaft 3 and a carriage 4. Accordingly, a space where two carriage bearings 2 are present is shut from a space where a magnetic disk 8 and a magnetic head 6 are present. The cover 1 may be corrugated so as to reduce a rigidity in a rotational direction of an actuator thereof. A lubricant of the carriage bearings 2 is prevented from adhering to the magnetic disk 8 and magnetic head 6. It is hence restricted that a motor becomes unable to start or the magnetic disk, magnetic head is damaged because of the adhesion of the magnetic disk 8 to the magnetic head 6 when a spindle stops. Reliability is improved.

Filed: 1994-04-27
Abstract: PURPOSE:To estimate with a simple constitution and high precision a slide angle which is an angle which the advancing direction of a vehicle and longitudinal direction of the vehicle body during the turning make, with regard to a vehicle status estimation device. CONSTITUTION:A longitudinal vehicle speed sensor 12 which detects a vehicle speed mu in the longitudinal direction of the vehicle is arranged on the longitudinal axis line of the vehicle 10. A longitudinal acceleration sensor 14 which detects an acceleration Gx in the longitudinal direction of the vehicle and a yaw rate sensor 16 which detects a yaw rate tau during the turning of the vehicle are arranged in the vicinity of center of gravity of the vehicle. A vehicle slide angle calculation unit 22 of an ECU(Electronic Control Unit) 20 obtains a longitudinal component Sx of a centripetal force S generated during the turning of the vehicle by substracting du/dt from an acceleration Gx. Since the longitudinal component Sx is a product of a width direction vehicle speed v and a yaw rate tau, v=(du/dt-Gx)/rho is obtained by reverse calculation, and a vehicle slide angle beta is obtained as beta=tan<-1>(v/mu).
