    Abstract: Multilayer opto-electronic module structures and their method of fabrication. Alternate layers of light conducting material and light isolating material are formed on a substrate and on each other. Isolating bars are formed in a predetermined pattern within the layers of light conducting material to define optical channels or chambers. Suitable illuminating and detecting means may be included within the channels using the isolating materials as electrical conductors so as to perform logic, memory and display functions.

    Abstract: An air bearing slider assembly includes a U-shaped magnetic head and a monolithic glass body which is formed in the glassy state so as to chemically as well as physically bond the head thereto, a nonmagnetic gap in the base of the head being disposed at an air bearing surface of the glass body to facilitate noncontact magnetic recording. The slider assembly is fabricated using a mold having a central cavity which defines the desired configuration of the glass body and which positions the magnetic head at a selected location relative to the glass body to be formed. The mold cavity is filled with a fluid glass composition which solidifies as a monolithic body in bonded relation to the head.

    Abstract: A transparent, protective coating overlies a photoconductive layer and is integral therewith. The coating, which has a resistivity at least equal to the dark resistivity of the photoconductive material, has a thickness in the range of 50A4000A. The coating is deposited on the photoconductive layer by sputtering through utilization of a high frequency alternating voltage whereby the properties of the coating may be controlled. When applying the high frequency alternating voltage, the power is kept low to produce a relatively high compressive stress of the coating. Controlling the power results in controlling the compressive stress of the coating. The temperature of the photoconductive layer may be maintained at a sufficiently low temperature so that the photoconductive layer retains its photoconductive properties.

    Abstract: In an electro-optical device, Fig. 1, comprising a photo-conductive element 11 in series with light source 13 and an A.C. power supply 12, the light source being optically coupled to the photo-conductor whereby the device may be triggered on by a short duration light pulse from a separate source 15 and remains triggered on due to the optical feed-back between 11 and 13, the photo-conductive element is arranged to exhibit current undershoot (see Journal of Physics and Chemistry of Solids, Vol. 1, No. 4, 1957, pages 234-248), whereby, in response to the termination of a subsequent light pulse equal to or greater than a predetermined intensity and duration from source 15, the resistivity becomes for a time greater than normal and causes light source 13 to extinguish and the device to trigger off. As illustrated, the light source comprises an electroluminescent element. In another embodiment, Figs. 7 and 8 (not shown), a neon tube is used. A display panel, Fig. 3, may be made of an array of devices as shown in Fig. 1 by forming between glass plates 32, 33 and transparent conductive layers 31, 34 an electroluminescent layer 35 bearing individual photo-conductive elements 30. A picture is set up by scanning the panel by an appropriately controlled flying-spot scanner 39 and any changes necessary in the picture are effected by illuminating areas to be darkened by a slow scan. Alternatively, the entire display may be blanked by unfocused illumination of long duration or a high intensity scan and then a further picture imparted by a low intensity scan. Photo-conductive material said to exhibit the current undershoot phenomenon to a sufficient pronounced extent comprises cadmium selenide with copper and silver acceptor atoms and chlorine donor atoms. In another form of device, Fig. 4, the photo-conductive element 41 is shunted by a normal resistive element 42 chosen so that the potential distribution in the circuit is such that the device is normally "on" with light source 44 (an electroluminescent element) producing light. If light from a separate source 46 of sufficient intensity is now impinged on element 41 for a sufficient period and subsequently extinguished, the resulting rise in resistance above normal, due to current undershoot, extinguishes source 44 and triggers the device off. The device persists off only momentarily, for the photo-conductive element reverts towards its normal resistance and once again allows source 44 to come on. A device as described in connection with Fig. 4 may be constructed as shown in Fig. 6 by forming on a glass plate 61 in successive layers: a transparent tin oxide electrode 62, an electroluminescent element 63, an insulator 64, a photo-conductive element 66 and a resistive element 67 formed of tin oxide. A hole 65 in insulator 64 allows a common connection to be established between elements 63, 66 and 67.

    Abstract: 1,149,195. Coating with glass. INTERNATIONAL BUSINESS MACHINES CORP. 7 June, 1966 [28 June, 1965], No. 25229/66. Heading C1M. [Also in Division B2] An object is coated with a layer of particles of glass by placing the particles at the bottom of a container, mounting the object over the particles, and directing a gas at the bottom of the container to form a cloud of particles around the object. The term " cloud of particles " excludes fluidized beds. The object may be of Be/Cu, it may be a chain store memory device or a semi-conductor device, e.g. of Si, and the particles may be of borosilicate glass with matched linear expansion coefficient. The particles may have size distribution:
