Abstract: In the manufacture of a monolithic LED array, in particular a matrix array, in which portions of the array are electrically isolated from one another by channels cut or etched through the slice of n-type material, the channels are formed in two stages, relatively wide channels first being formed from the back surface of the slice to within 50 microns of the front surface, and filled with a glass frit which is bonded to the semiconductor material on each side of the channel, then narrower channels are formed from the front surface of the slice to meet the glass in the initial channels, and are similarly filled with glass frit. A glass powder suspension is introduced into each set of channels by spreading or spinning over the surface of the slice, or by electrophoretic deposition and/or capillary action, then the liquid suspension medium is removed and the glass powder is sintered.

Abstract: A metal-oxide-semiconductor (MOS) structure and method for its fabrication wherein all contact hole locations are simultaneously photolithographically defined in the gate oxide layer and openings are etched at these locations prior to the deposition of polysilicon, which is then etched to form interconnections and contacts. The completed structure contains a thick oxide layer which forms an insulating dielectric which surrounds and is self-aligned with the contact holes and obviates the need for the commonly used intermediate layer of phosphosilicate glass. The width of the polysilicon contacts to sources and drains is less than the width of the active channel formed in a conventional n-channel silicon gate Metal-Oxide-Silicon field-effect transistor so that significant misalignment in the channel length direction between the opening in the gate oxide at a contact hole location and the polysilicon pattern will not cause failure of individual field effect transistors (FETs).

Abstract: A method for forming semiconductor memory devices each including either an MNOS-type or MOS-type transistor and an MNOS-type capacitor. Upon a silicon substrate there is formed a thick layer of oxide which defines the individual cells and provides separation therebetween. Exposed portions of the substrate are thermally oxidized to form a layer of thermal oxide upon which is subsequently deposited a layer of silicon nitride and a layer of polycrystalline silicon. The polycrystalline silicon is then masked and portions there are removed through apertures and the mask. The substrate is then irradiated at a non-perpendicular angle through the apertures in the mask and predetermined remaining portions of the layer of thermal oxide are removed. Exposed portions of the substrate at this point are diffused with an impurity of the opposite conductivity type to the substrate.

Abstract: Aluminum/copper alloy conductors are made by forming a patterned layer of copper on a layer of aluminum.

Abstract: A tri-metallic electrical contact consisting of a head wire piece and a base wire piece which abut to an intermediate piece at its opposite ends, is produced by cold press operations performed by first and second die and punch sets. The first die and punch set causes plastic deformation of approximately only a half part of the aligned wire pieces, while keeping another half part of these pieces not deformed. The second die and punch set imparts, subsequent to, and independently from, the cold press operation performed by the first die and punch set, plastic deformation to the other half part of the pieces, whereby the abutting surfaces of the three wires are prevented from sliding movements laterally relative to each other during the cold press operations, and whereby irregular or insufficient deformation of the wires due to the differences of yield points of the wires is prevented.

Abstract: A shut-off device (104) controlling the operation of the motive means such as an electric motor which powers a tool such as a chain saw (12) having a housing (14) with a brake (34) therein operative to stop the chain saw (12). The shut-off device (104) includes a switch (54) biased off and shiftable on. A pivotable or shiftable trigger (72) is shifted toward but remains out of contact with the switch (54). A link (92) is caused to shift responsive to the brake (34) when the brake becomes operative, but the link is otherwise disposed intermediate the switch (54) and the trigger (72) to permit the trigger (72) movement to actuate the switch (54). However, on brake actuation the link is removed from a path of motion between the switch (54) and trigger (72) thereby to restore the switch (54) to "off" position. Once the link (92) is removed from the path of motion it cannot be reinserted therein until after the trigger (72) is released.

The system utilizes a probe which has a plurality of faces which are interconnected so as to form two parallel "X" co-ordinate probe surfaces (12) and two parallel "Y" co-ordinate probe surfaces (14).

In this manner, measurements along the "X" and "Y" co-ordinates can be made and recorded at the instant the probe contacts the respective surfaces. An automatic unlatching feature is provided wherein the probe must be a predetermined distance from both the "X" and "Y" surfaces before the system automatically resets.

The casing can be rotated manually relative to the housing to adjust the tilting edges of the plate.

Abstract: A stiff, straight spar is allowed to pivot about an anchor on the seafloor. he location of the bottom with respect to the top is then determined by measuring the tilt of the spar and computing the offset of the bottom relative to the top. The straight member uses its internal buoyancy to remain erect and stable while the weight of the anchor keeps it in place on the seafloor. The top of the spar is tracked by shore stations while the tilt and heading of the spar is monitored by an instrumentation system. Simultaneous readings of the shore instruments and the spar's tilt and heading indicators allow direct determination of the anchor location relative to the shore. An air ballast control enables the apparatus to be easily maneuvered on the ocean bottom by divers or on the surface and an internal plumb bob system allows calibration of the overall system.
