Granted: 2001-05-01
Abstract: The present invention relates to the formation of metal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot of matrix metal is surrounded by a permeable mass of filler material. An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material, at least at some point during the process, which permit the shaped ingot of matrix metal, when made molten, to spontaneously infiltrate the surrounding permeable mass of filler material. After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot of matrix metal.

Title: Laser diode focusing module for divergent light source
Inventor: KRICHEVER MARK
IPC: G06K7/10
Filed: 1989-10-26
Granted: 1994-07-26
Abstract: A focusing module for divergent light emitted from a source such as a laser diode.  The focusing module consists of telescoping cylindrical members which focus by sliding the members along their central axis and permanently adhering the members to each other after focusing.  The focusing lens is embodied in a lens assembly which prevents direct contact between the lens surface and the lens seat in one of the cylindrical members.  Axial rotation between the cylindrical members, and between the base and the module is prevented by a series of notch and key elements.  Consequently, the opening of the focusing module is fixed with respect to the cross-section of the light emitted, and can be shaped to match the cross section of the laser light beam thereby permitting maximum emission of focused light.

Abstract: A closing device is employed in an article of furniture having furniture components including a furniture body and a drawer for moving the drawer to a fully inserted position within the furniture body.  The closing device includes a pin member fixed to one of the furniture components and a tiltable member mounted on the other of the furniture components for displacement relative thereto in opposite first and second directions.  The pin member and the tiltable members are engaged when the drawer is in the fully inserted position.  Upon the drawer being moved in the direction outwardly of the furniture body, the tiltable member displaces relative to the other furniture component in the first direction.  A spring acts on the tiltable member and the other furniture component to urge relative displacement therebetween in the second direction.  When the pin and tiltable members are in engagement, the spring urges the drawer to move in a direction inwardly of the furniture body to the fully inserted position.  When the tiltable member displaces relative to the other furniture component against the force of the spring means in the first direction to a predetermined relative position, the tiltable member is caused to tilt in a first pivot direction about an axis to a locking position whereat the tiltable member is locked to the other furniture component and engagement between the pin member and the tiltable member is released.

Title: Method and apparatus for compensating for shutter speed variations
Inventor: FARRINGTON DAVID L
IPC: G03B7/16
Filed: 1990-10-26
Granted: 2001-01-16
Abstract: An exposure control system for a photographic camera employing a scanning type shutter that includes a pair of cooperating shutter blade elements automatically compensates for exposure altering variations in shutter blade element speed that may occur from one exposure interval to another. The exposure control system includes an encoder to provide information on the actual position of the shutter blade elements as a function of time during an exposure cycle. The encoder generates a series of pulses representative of relative blade element position as the blades are moved during the exposure cycle.      The time between these pulses is measured and directly converted into a signal representative of shutter blade element speed or velocity. This shutter blade speed signal is then employed to alter the duration of an exposure interval to compensate for any shutter blade element speed variations.

Title: Thermal ink jet printhead with location control of bubble collapse
Inventor: DESHPANDE NARAYAN V
IPC: B41J2/05
Filed: 1991-06-11
Granted: 1995-12-05
Abstract: A thermal ink jet printhead is disclosed having an ink channel geometry that controls the location of the bubble collapse on the heating elements. The ink channels provide the flow path between the printhead ink reservoir and the printhead nozzles. In one embodiment, the heating elements are located in a pit a predetermined distance upstream from the nozzle. The channel portion upstream from the heating element has a length and a cross-sectional flow area that is adjusted relative to the channel portion downstream from the heating element, so that the upstream and downstream portions of channel have substantially equal ink flow impedances. This results in controlling the location of the bubble collapse on the heating element to a location substantially in the center of the heating elements.

Consequently,    without    strictly controlling the film thicknesses of the first and second AlN films, a magneto-optical storage device with stable performance suitable  for practical use can be produced easily .
