Title: Disk driving motor for magnetic disk drive
Inventor: KONNO MAKOTO
IPC: G11B17/028
Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To reduce frictional resistance without detriment to a function as a chucking magnet for a disk table in the disk driving(DD) motor of magnetic disk drive. SOLUTION: The DD motor 11 of 3.5 inch floppy disk drive has a rotor 28 formed integrally with a disk table 38 and is disposed on one side of a frame 12. A case of the rotor 28 and the disk table 38 is formed with a two-stage discoid plate 15 consisting of a steel plate in such a shape that a small diameter discoid plate 19 is arranged in the middle of the upper surface of a large diameter discoid plate 18. The chucking magnet 32 molded of a resin (r)mixed with magnetic powder m is disposed on the upper stage surface of the two-stage discoid plate 15. Since the two-stage discoid plate 15 is worked as a back yoke of the chucking magnet 32 at the time of chucking a 3.5 inch floppy disk 39, a content of the magnetic powder m is not required to be too much. Consequently, the frictional resistance between the chucking magnet 32 and a hub 40 of the 3.5 inch floppy disk 39 can be reduced.

Title: Taxi-meter measuring device
Inventor: SUGAMA ETSUO
IPC: G01D4/00
Filed: 1983-02-21
Abstract: PURPOSE:To perform accurate determination in a short time, by predicting the error at a changing point in each fare display in a state after the displayed fares have been changed a plurality of times, and displaying passing or failure. CONSTITUTION:A mark 19 is attached to a timer 15. Meanwhile, a pulse generator 23 is attached to a driving wheel, and the effective length of the circumference of the tire is computed by an effective-circumference measuring part 13. The mark 19 is detected as one pulse at every one rotation of the tire 15 in a free-charged-running-distance detecting part 35. A pulse is generated at every time the fare display, which is detected by a fare-display-change detecting part 42, is changed. The counted value of the tire pulse is taken out every time when said change pulse is obtained. The result is multiplied by the effective circumference length of the tire, and the running distance is computed. Based on the running distance, an information processing part 43 predicts the running distance at the later change in fare display and an error from a reference value. Based on the predicted error, passing or failure of a taxi-meter is displayed.
