Title: Dynamic pressure type air bearing
Inventor: MARUYAMA TERUO
IPC: F04D29/056
Filed: 1988-06-29
Abstract: PURPOSE:To provide serviceability under such environments as with much dust afloat by furnishing No.1 spiral groove, which is to send by pressure the lubricating air to the backmost in a bearing member, and No.2 spiral groove to send out the air to an open end at the mating surfaces of a rotary shaft or a bearing member, and by installing a filter on an air passage which is to put the boundary between the two grooves in communication with the outside. CONSTITUTION:Through the pumping action of No.1 spiral groove 5 associate with rotation of a rotary shaft 1, the lubricating air 3 between this rotary shaft and a bearing member 2 is sent by pressure toward the backmost in the bearing part so as to boost the pressure. The bearing effect is generated through wedge effect of the lubricating air 3 applied between the internal surface of the bearing member 2 and the external surface of rotary shaft 1. As the air is also sent off toward the open end of the bearing member 2 through the pumping action of No.2 spiral groove 6, external dust is prevented from intruding into gaps in the bearing. As the air at the atmospheric pressure with the dust removed by passing through a filter 9 is supplied to the boundary 7 of the two grooves, no obstacle will be generated for the load capacity of the bearing.

Title: Baking of ferrite core
Inventor: NAKAMURA SHIGEHIKO
IPC: F27D3/12
Filed: 1989-06-23
Abstract: PURPOSE:To obtain a ferrite core with small deformation due to expansion and contraction by baking the ferrite cores arranged on the inclined surfaces of support plates with wedge-shaped sections erected on a hearth plate. CONSTITUTION:A baking device 1 made of zirconia containing hafnium is used wherein a plurality of support plates 4 with wedge-shaped sections are erected integrally with a hearth plate 3 as spaced from one another in parallel. A plurality of -shaped ferrite cores 2a and U-shaped ferrite cores 2b are arranged on the inclined surfaces of the support plates 4 of the baking device 1 with spaces therebetween. ( and U are 'kanjis'). While shifts are generated between the ferrite cores and the support plates 4 due to a difference between the expansion coefficient and contraction coefficient of the core and the plate 4, friction between the cores and the plates 4 is small because the cores smoothly move along the inclined surfaces. Thus, the cores with small deformations due to expansion or contraction can be obtained and further the cores after the baking can be maintained at a high permeability.
