Appl. No.:

7/006466

Inventors:

John A. Seitz - Pewaukee WI

International Classification:

E04B 132

US Classification:

52 82

Abstract:

A building structure includes an upstanding substantially vertical wall portion constructed from a plurality of interlocking wall sections and forming a closed shape. The wall sections are formed from a thermally insulating material. A retainer band is provided for placement about the periphery of the wall portion, and is adapted to be tensioned to maintain the wall portion in its closed shape. The exterior surface of the wall portion is coated with a concrete-like material, or any other satisfactory weather resistant coating material, to protect the insulating material of the wall sections from weather. A roof structure is adapted to be placed atop the wall portion. In one embodiment, the wall portion is circular in plan, and the roof structure comprises a plurality of wedge-shaped sections, with the base portion of the wedge sections adapted for placement atop the wall portion. The retainer band overlaps the base portion of the wedge sections and interlocks the roof and the wall portion. The roof sections are also constructed of an insulating material, and are coated with a weather resistant material after installation to protect the roof sections from weather.

Abstract:

A disk drive motor has a mounting plate with a circuit board on one face and a cylindrical hub extending therethrough. A stator is secured to the plate and exterior of the hub. A cup-shaped rotor overlies the stator and has a rotor shaft journaled in the hub by spaced sealed precision bearings. The bearing opening includes an integral ledge which forms bearing chambers having smooth, uninterrupted walls within which a bearing is secured. Each bearing has an outer race secured within the chamber and an aligned inner race secured to the shaft, with end sealing members to seal the bearings. Spring means are located between each ledge are the inner races of the corresponding bearings to load the bearings. In assembly, the one bearing is assemblied on the shaft and inserted into the hub with the outer race adhesively bonded in place. The opposite bearing is close fitted into the opposite bearing and the shaft is pressed into the bearing during the assembly.
