A system conveys two gases separately until controlled delivery and gas mixing are desired. The device maintains separation between the two gases with sealed, high temperature materials, and a geometry that contains gas flow channels that do not allow gas mixing. The present design provides a seal at the interfaces between components. An outer ring and an inner spool are assembled together to form a single component that accommodates the input of two, initially separate gases, and then contains and conveys the two gases separately to an exit surface where outlet holes allow the two gases to mix and react in a controlled manner upon exiting the component. The inlet holes for both gases are located on one side of the spool. The exit holes are formed in a centralized, alternating, completely interspersed array or grid-like pattern on the opposite surface of the spool.
System, Method, And Apparatus For Conversion Bonding Of Precursor Subcomponents Into A Unitary Monolith
A process for converting precursor objects into a unitary ceramic object produces, for example, a ceramic, optical scan mirror that is formed from at least two pieces. An optical section has at least one optical surface and at least one attachment surface, and a support section has at least one attachment surface and preferably has a mounting area. The optical and support sections are formed as separate pieces from a precursor material, such as graphite, such that a selected support section can receive any of a plurality of optical sections having different sizes, shapes, or orientations. To form the mirror, the attachment surfaces are placed adjacent each other, and then the sections are converted simultaneously to a ceramic material, such as silicon carbide, to form a monolithic scan mirror.

International Classification:
C23C 1600
US Classification:
118500
Abstract:
An apparatus for holding a plurality of semiconductor wafers during heat treatment of the wafers in a furnace, which apparatus comprises a plurality of support members or rails extending essentially vertically between a top and bottom plate. At least two of the support members are located toward the front of the carrier where the wafers are inserted, and at least one support member is located toward the back of the carrier. A first plurality of slats is attached to one of the front support members and to a back support member such that the space between the top surface of one slat and the bottom surface of the next higher adjacent slat forms a slot for receiving a portion of a semiconductor wafer. A second plurality of slats is attached to another front support member and to a back support member to form corresponding slots on another side of the carrier for receiving another portion of a semiconductor wafer. Preferably, each slat contains at least one raised structure which is used to support the underside of a semiconductor wafer.

International Classification:
A63B 69/00 A63B 43/00
Abstract:
A device for training a person to throw a ball includes a body. The body defines a first planar surface, a second planar surface, and a curved surface. The first planar surface is defined at a first end of the body. The second planar surface is defined at a second end of the body. The curved surface is defined between the first planar surface and second planar surface. The device has a center of mass that is located outside of the geometric center of the device.

International Classification:
A63B 69/00
Abstract:
A pitch training ball includes a center portion, a first cap, and a second cap. The center portion is opaque and has a first planar surface at a first end thereof, and a second planar surface at a second end thereof opposite to the first end. The first cap portion has a first base that is adjacent to the first planar surface. The second cap portion has a second that is adjacent to the second planar surface. The first cap, the center portion, and the second cap cooperate to define a baseball shape. The first and second caps are transparent to translucent.
