Abstract: A platinum-cadmium sulfide Schottky barrier photovoltaic detector which is capable of sensing near ultraviolet and short wavelength visible radiation with extremely small response to wavelengths longer than about 5200 angstroms. The detector is fabricated with both the ohmic and barrier contacts located on the same side of the cadmium sulfide substrate to facilitate wire attachment by high-speed bonding techniques. A titanium-gold-titanium infrared shield structure is deposited directly on the substrate and is utilized to provide a connection between the ohmic contact and the substrate. An insulating layer of silicon dioxide covers the shield structure. A thin layer of platinum is deposited directly on the substrate in a small central optically active area surrounded by the insulated shield structure. A metal boundary layer overlies the periphery of the platinum layer and prevents the barrier contact metalization from affecting the properties of the Schottky barrier. Both the ohmic and barrier contacts may be formed of a titanium adhesive layer and a layer of gold. The gold portions of these contacts touch the shield structure and the boundary layer through separate windows etched in the silicon dioxide insulating layer.

Abstract: In order to be able to use magnetostrictive alloys effectively in principally vibration applications an effective magnetic circuit is required. On account of the resistive losses in coils the magnetic working point should be achieved with permanent magnets. In order to re- magnetize permanent magnets a lot of energy is required and as the relative permeability (outside the casing area) is low it is difficult to direct a varying superpositioned flow through permanent magnets. The solution is instead to have two magnetic circuits, one for static flow caused by permanent magnets and a magnetic circuit which is delimited by permanent magnets for the varying magnetic flow caused by coils. The coils are configured so that a positive flow through the coils causes an increase in the magnetic flow in one magnetostrictive rod and a reduction in the flow in the other rod. Depending upon whether the rods are of the same (both positive or negative) magnetostriction or different (one positive, one negative), different kinds of movement can be obtained. <IMAGE>
