Abstract: A wordline decoder for high density flash memory is described with negative voltage capability for memory operations such as erase. A main decoder is shared with a plurality of wordline driver circuits to reduce wiring congestion and overall layout size. In a second embodiment a wordline decoder for fast read access is provided in which a high speed positive voltage decoder is separate from the negative voltage decoder with the addition of a triple well NMOS transistor into the inverter driver circuits. The use of triple well NMOS transistors reduces circuit and layout complexity.

Abstract: A cable bolt comprises a cable with a tubular yielding fixture at one of its ends. The pull-off load of such yielding fixture can be adjusted to a desired value. This is achieved by unwinding one end of the cable and inserting a slug over the kingwire. Then, the peripheral wires are wound again over the kingwire forming a bulge in the cable where the slug is located. The yielding fixture is then slid on the cable and forced over the bulged portion of the cable, while measuring the load required to achieve this operation, which also becomes the pull-off load of the yielding fixture. Finally, any part of the cable protruding from the fixture is cut-off to form the cable bolt with the desired yielding fixture at its end.

Abstract: A telecommunications cable is disclosed in which a plurality of inwardly extending projections from the cable jacket, form a first and second plurality of substantially parallel longitudinal channels within the cable jacket. The first and second plurality of longitudinal channels are spaced apart from one another with respect to a reference line that transverses the cable, wherein the plurality of inwardly extending projections provide the spaced apart distance between the first plurality and the second plurality of longitudinally extending channels and between corresponding transmission media disposed within the first and second plurality of longitudinally extending channels. With this arrangement, cross talk between the transmission media within the cable is reduced and alien crosstalk between adjacently disposed or stacked cables is also reduced.

Abstract: A method for making cable of at least two thermoplastic insulated electrical conductors by thermal bonding. Two electrical conductors are moved into an extruder and are coated independently with heated thermoplastic insulation which maintains concentricity of each conductor with respect to the surrounding insulation. The insulated conductors are held in a spaced relationship until the insulation sets and then the heated insulated conductors are touched together causing the heated insulation to fuse together thereby joining them.

Abstract: An engine has a pair of rotors, both housed within the same housing. The housing has an interior cavity which is preferably spherical but need only be partially spherical, the remainder at least having rotational symmetry. Each rotor is mounted on an axis that passes through the center of the cavity, the respective axes of the rotors being at an angle to each other, with the center of each rotor being at the center of the cavity. The rotors interlock with each other to define chambers. Vanes or pistons defined by a contact face and a side face protrude from the rotors. The side faces and contact faces, and the housing interior define chambers that open and close as the rotors rotate. Each contact face of one rotor is defined by the rotation of a conical section of material on the other rotor, so that there is constant linear contact between opposing vanes on the two rotors, at least on one side of the engine. The rotors may face each other or be one inside the other.

Abstract: A method and apparatus for producing a thermoplastic container-shaped intermediate or article having biaxially oriented side walls and a bottom having an unoriented portion surrounded by a biaxially oriented transparent portion. In the method, a sheet of thermoplastic at its orientation temperature is secured over the mouth of a forming tube. A plunger having a circumscribing sharp edged lip and a plunger follower sandwich the thermoplastic sheet and the plunger and plunger follower are driven into the forming tube while preventing the circumscribed portion of the thermoplastic from becoming oriented. Thereafter the thermoplastic is blow formed to yield a container-shaped intermediate. The final container is formed by heat shrinking the intermediate onto a male form having a predetermined size, shape and texture. The apparatus includes the forming tube, plunger, plunger follower and pressurized air for performing the method.

Abstract: A rear suspension system for a bicycle. The system directs the rear wheel along a predetermined, S-shaped path as the suspension is compressed. The path is configured to provide a chainstay lengthening effect only at those points where this is needed to counterbalance the pedal inputs of the rider; at those points in the wheel travel path where there is a chainstay lengthening effect, the chain tension which results from the pedal inputs exerts a downward force on the rear wheel, preventing unwanted compression of the suspension. The system employs a dual eccentric crank mechanism mounted adjacent the bottom bracket shell to provide the desired control characteristics.

Abstract: An improved method and apparatus for cleaning liquid-carrying hoses, and the like. A suitable cleaning solvent is passed under pressure through the hose. The pressure of the solvent delivered to the hose is measured and used to control the pressure of compressed air mixed with the solvent to maintain a turbulent flow of a predetermined mix ratio for various solvent pressures. The turbulent solvent/compressed air mixture increases scrubbing of the hose to reduce the cleaning time and the quantity of solvent required to clean the hose.
