Abstract: Improved frequency characteristics can be achieved by using input/output pads on a surface mount block filter which pads are mounted on mesas formed by troughs cut through the dielectric material and metallization.

Abstract: A two piece split bearing assembly is provided and consists of an outer race ring, an inner race ring and a plurality of antifriction elements all split in half. A male V-groove is formed on each end of one half of the outer race ring and the inner race ring while a female V-groove is formed on each end of other half of the outer race ring and inner race ring. When the two halves of the inner race ring and outer race ring are mated together with the antifriction elements between they will form the bearing assembly.

Abstract: A PLZT based shutter system reduces flare produced by reflective surfaces normally associated with PLZT based and other SLR shutter systems by eliminating a diffraction mirror and using highly reflective electrodes directly on the PLZT element to function both as the reflective mirror and as the electrodes to produce the E field in the PLZT element. The invention has an improved performance by reducing flare and has a reduced parts count improving its manufacturability and reliability.

Abstract: A manually-operated device for applying a very thin material, such as roll leaf, from a roll onto a flat surface so as to imprint the material and produce an artistic result. The device has a dispenser for holding the roll of material, and the material is guided through a predetermined path under a heated stamping roller, the temperature of which is automatically controlled and maintained at a desired temperature. By using handles on the sides of the device, the user advances the roller over the material, which is dispensed smoothly, so as to apply the material to the selected surface. The device includes a manually-operated cutter to facilitate cutting of the material on a straight line when the desired amount has been applied.

Abstract: A PLZT wafer modulates a laser light beam while dissipating heat into a heat sink. The rear side of the wafer is coated to act as a mirror to reflect incoming light and to transfer heat from the wafer. The front side of the wafer has electrodes, separated by a gap through which a laser light beam can pass. An incoming light beam is modulated by the PLZT when it is energized by an electric field on the two front side electrodes. The mirrored side reflects the beam so that it exits the front side.

Abstract: An electro-optic display having either variable-color or selectable-color capability is disclosed, with each having particularly efficient electrode patterns for achieving color control. Each implements a passive display utilizing an electro-optic material such as PLZT having one of these types of electrode patterns and aligned with an appropriate multi-colored filter. By applying D.C. control voltages to these sets of electrodes, which are sufficiently small to form unit cells, variable or selectable color is perceived. The patterns may be arranged in a sequence of any length or width, with the three-shutter pattern featuring no surface-mounted crossovers.
