Inventor: OCHI NAOYA
IPC: B60C11/11
Filed: 2001-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic tire that can improve ice performance and improve snow performance and drain performance. SOLUTION: The termination of cross grooves 32L in intermediate land portions 22L can improve the rigidity of the intermediate land portions 22L to improve ice performance. The formation of a plurality of lateral grooves 16L in center land portions 14L and substantially parallel formation of a tread end side edge of an inner circumferential groove 20L to a tire circumference can improve drain performance especially of a tread part center region CW. The setting of a negative ratio throughout a tread part 42 in a range of 28% to 37% can increase a grounding area while maintaining a draining function to improve ice performance.  A smaller negative ratio of the tread part center region CW whose width is one fifth of a tread width H than the negative ratio throughout the tread part 42 can increase a land portion volume especially in the tread part center region CW to improve braking performance on ice.

Title: Fluid dynamic pressure bearing manufacturing method, fluid dynamic pressure bearing, motor, and disk device
Inventor: OSAWA HARUSHIGE
IPC: H02K5/16
Filed: 2001-11-16
Abstract: PROBLEM TO BE SOLVED: To solve such a problem with a fluid dynamic pressure bearing of shaft rotation type used for the motor of a disk device and having a pair of radial bearings on the upper and lower parts of a shaft that, when the fluid dynamic pressure bearing is designed and manufactured, a definite index for minimizing the tilt vibration of a disk against external vibration was not produced. SOLUTION: The index capable of determining an optimum bearing structure is defined by setting the value of a constant K specifically determined when a fluid bearing structure is determined at 5×10<6> or higher. Thus, the performance of the fluid dynamic pressure bearing can be evaluated and optimized at the stages of the design and production though the performance could be evaluated only when the motor is trial-manufactured and incorporated in the disk device, and an excited response test thereof is performed. As a result, the fluid dynamic pressure bearing and the motor having the same can be designed and manufactured at a low cost in a very short period, and the disk device capable of developing a high performance also against the external vibration can be provided.
