Abstract: D-22,658 ELECTROSTATIC DISCHARGE-PROTECTED SWITCH                   By Robert A. Sherwood and Svein T. Nordberg ABSTRACT OF DISCLOSURE     A tactile matrix switch has a planar electrically conductive film dielectrically spaced between contacts of individual switch elements and an actuating mechanism such as a finger on the body of a human being who may carry an electrostatic charge.  Some switch contacts are electrically connected through external circuitry to ground.  The conductive film is also electrically connected to ground.  When a human operator carrying an electrostatic charge brings his finger near the face of the matrix switch for applying a tactile force to actuate an individual switch element, the conductive film electrically conducts the electrostatic charge to ground and away from the switch contacts for protecting the electrical circuitry connected to the latter.  In one embodiment, the conductive film is electrically conductive printer's ink, having a resistivity of less than 50 k ohms per square, that is silk screened onto the back of a face plate of the matrix switch.  In an alternate embodiment, the conductive film is printed onto the same broad side of a flexible dielectric plate to which the tactile force is applied, switch contacts being formed on the opposite broad side thereof.

Abstract: ABSTRACT:          "Radiation-sensitive semiconductor device."     In a radiation-sensitive semiconductor device, for example, a quadrant diode, consisting of several rec-tifying junctions (5) the mutual distance between said junctions (5) can be considerably reduced by keeping the junctions (5) cut off by means of circuit elements ( 11, 14) in such manner that associated depletion regions (12) touch each other. Charge carriers generated between two junctions (5) are substantially always collected by the good junction (5). A low crosstalk and good high-frequency properties can be realised. Furthermore, the semiconductor body (1) in which the rectifying junctions (5) are realised may comprise further circuit elements, which enables integration of the radiation-sensitive semiconductor device with other elements.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention concerns a device to spread out flat the fibres of an optical cable, which has first been stripped, so that the fibres can be cut across precisely aligned cross-sections, thereby allowing them to be butt-jointed individually with the fibres of another cable, in a splicing operation.  This device comprises hand-operated mechanical means of inserting blades, positioned on a diametrical plane of the cable, to separate the fibres into two groups.  One blade acts as a stop, while the first group of fibres is being gathered into the notches of one comb, while the other blade performs the same function for a second comb.  The combs and blades are then made to rotate in opposite directions, flattening out the group of fibres on a horizontal plane.  This device can be applied to optical fibres used for telecommunications.
