Abstract: A chip scale package structure formed by adhering a glass sheet having a pattern of holes matching a pattern of bond pads on a semiconductor wafer so that the pattern of holes on the glass sheet are over the pattern of bond pads on the semiconductor wafer. Metallized pads are formed on the glass sheet adjacent to each hole and in one embodiment a conductive trace is formed from each metallized pad on the glass sheet to the bond pad on the semiconductor wafer under the adjacent hole. In a second embodiment, a pad is formed on the glass sheet adjacent to each hole and the pad extends down the sides of the adjacent hole. The hole is filled with a metal plug that electrically connects the pad on the glass sheet to the bond pad on the semiconductor wafer. In each embodiment a solder ball is formed on each pad on the glass sheet.

Abstract: An orthodontic band (10) for placement on a molar tooth including a strip of flexible material (11), such as a stainless steel strip, having co-operating locking means (12, 13) located adjacent each end of the strip. Alternatively, the strip (6) may have an elongated tongue (62) formed at one end and slots (63, 64) for receiving the tongue at the other end. In use, the band is formed into a shape that will fit over a tooth and placed over the tooth. The band is then tightened to cause the band to closely fit to the tooth. An orthodontic cement is placed between the band and the tooth. The locking means (12, 13) on the band provides a frictional fit that may be sufficiently strong to hold the band in the desired configuration until the cement has set. Alternatively, the clamp may need to stay in place until the band and cement can provide a permanent set.

Abstract: A molded plastic storage container includes a lower tub section having a hinged front access panel, a detachable, hinged cover and internal dividers adapted to compartmentalize the container.

Abstract: The present invention is directed to an electrically conductive container with beveled edges and an improved blow molded carrier for efficiently storing and transporting such cases. The carrier has raised portions along its interior base which accommodate one or more of the containers. The invention is also directed to a process for storing electrically conductive containers, including blow-molding carrier means having beveled raised portions, and containers having beveled edges, and the insertion of the containers between adjacent raised portions of the carrier.

Abstract: A thermoplastic container has separate hinge means in the body and cover portions of the container which are similar or substantially identical. This four part hinged configuration simplifies tooling, and simplifies economy of production, while allowing easy assembly of the container and resulting in a secure hinge after assembly.

Abstract: A portable work station for transporting a device sensitive to external electrical forces and, in particular, to static electricity is provided. The work station which is manufactured from an electrically conductive composition which acts to shield the contents of the container from external electrical forces is provided with an electrically conductive window means and electrical charge grounding means all of which are in electrically conductive communication with each other. In one embodiment the work station is provided with an internal electrically conductive anti-static pad.

Abstract: A processor and processing method for treating flat discrete elements of photographic film, preferably in a disc format, includes the use of a spindle for receiving the elements in stacked, parallel relation normal to the spindle. The spindle mounted discs are rotated in a processing solution to provide relative movement between the discs and the solution, and are rotated while out of the processing solution to remove excess solution from the discs.

Abstract: An automatic rangefinder and focusing apparatus is provided for use with a camera for determining the distance from an object to be photographed to the film plane of the camera and for positioning the camera's objective lens to focus an image of the object in the film plane. The apparatus comprises a photoresponsive device and a light emitter device that projects light in angularly intersecting relation to the optical axis along which light is received by a photodetector incorporated in the photoresponsive device. The light projected by the light emitter device is amplitude modulated at a frequency functionally related to the distance from the camera at which that light intersects the optical axis of the photoresponsive device.

Abstract: Exposure control apparatus provides an exposure program in which an exposure aperture is related to shutter speed to produce an optimum compromise between both exposure parameters. The exposure control apparatus comprises a diaphragm defining an exposure aperture of variable size, and a shutter comprising first and second selectively movable shutter blades for sequentially uncovering and covering the exposure aperture, respectively, during an exposure interval. Shutter speed is varied automatically by moving the second blade a variable time before commencing movement of the first shutter blade. The second shutter blade and diaphragm are coupled together by a control member such that the aperture size as well as exposure interval are varied in proportion to each other prior to an exposure. A movable latch member operably associated with a level-sensing light-sensitive circuit latches the diaphragm in an aperture regulating position which is functionally related to scene light intensity.
