IPC: G11B19/20
Filed: 1991-11-07
Abstract: PURPOSE:To enhance the rigidity of a revolving shaft and to decrease vibration by setting the number of hubs for mounting and fixing disk-shaped recording media and the contact parts of the shaft at a plurality. CONSTITUTION:A relief 13 is formed on the outer peripheral surface of the revolving shaft 2 and the hubs 3 are fitted to the revolving shaft 2 in the positions near both ball bearings 8, 9 by two pieces of contact surface 11, 12. Magnetic disks 1 and spacers 5 are alternately stacked on the outer periphery of the hubs 3 and are pressed axially by a clamping plate 4, by which a disk rotating body is constituted. The mass of the disks 71, the spacers 5 and the hubs 3 can be appropriated near to the two ball bearings 8, 9 by adopting such a structure. The hubs themselves contribute to an increase in the bending rigidity of the revolving shaft. The primary resonance point is thus raised and the attenuation of vibration is made possible.

Title: Motor
Inventor: OBATA SHIGEO
IPC: H02K21/24
Filed: 1985-12-24
Abstract: PURPOSE:To prevent FG detection error from being increased by the leakage flux of a main magnet and reduce the unevenness of rotation, by setting the rotary section of FG on a rotor yoke at a position non-confronting the pole surface of the main magnet. CONSTITUTION:Magnetic flux coming from the N pole of an FG magnet 8 passes through a rotor yoke 4, and returns to the S pole of the FG magnet 8. Then, the magnetic flux of the FG magnet 8 is alternately changed with the rotation of a rotor section, and an FG stator coil generates the FG signal of frequency in proportion to the rotational speed of the rotor. Magnetic flux generated from a magnet 5 is shielded by the rotor yoke 4, and the rate of the flux coming up to the FG stator coil is extremely low. Accordingly, the noise of frequency in proportion the number of magnetizing poles of the main magnet 5 is reduced to a very low level as compared with FG signal.

This powder mixture is stuck together by means of cold pressurizing sticking (e.g. cold press or cold roll) into the desired shape and then heated to the prescribed temp. by hot melting sticking means, by which the rion powder containing the desired metal and the pure iron powder are melted and stuck together and the components are evened.  Further, the material is passed through a hot melting, pressurizing, and sticking means (e.g. hot roll) and pressurized and formed into a plate-like state perfectly free from blowholes. By this method, the iron plate containing the desired metal by the desired numeric value percent can be produced.
