A mold is provided for receiving and processing the ceramic powder thereby forming a ceramic billet. Shaping of the ceramic billet is undertaken to form a near net-shaped ceramic bearing. Thereafter, the near net-shaped ceramic bearing is sintered resulting in a sintered ceramic bearing. After sintering, the ceramic bearing is further shaped or machined. After forming the ceramic bearing, at least two air inlet ports are formed in the body portion of the bearing in fluid communication with air channels having preferably a spiral pattern formed in at least one flange portion of the bearing.

    摘要: A method of fabricating a modulator for modulating an incident beam of light includes a substrate having a cavity formed therein and a plurality of spaced-apart deformable elements formed in the cavity. The deformable elements each has a base layer, a poled magnetic layer formed in the base layer and a first light reflection layer deposited on the magnetic layer for reflecting an incident beam of light. Between adjacent deformable elements on the base of the cavity is arranged a second light reflection layer. A conductive element formed in the substrate electro-magnetically energizes the deformable elements to deflect in the cavity. Incident light passing through each one of the first light reflection layers is caused to destructively interfere with light reflected from the second light reflection layers thereby causing modulation of the incident light.

    摘要: A method of making a modulator for modulating an incident beam of light uses a substantially planar light reflection surface formed by a light reflection layer associated with a plurality of deformable elements and a light reflection layer associated with a plurality of fixed elements. The fixed and deformable elements are arranged in a cavity of a substrate supporting the modulator. Light is modulated when a current is applied to a conductive element operably associated with the deformable elements causing the light reflective layer associated with the deformable element to deflect towards the base of the cavity from its substantial planar relations with the light reflecting layer of the fixed element.
