  • Counteraction of semiconductor impurity effects
    Patent number: 4692558
    Abstract: Method of counteracting the effects of undesired contaminants in an amorphous semiconductor, and the resulting semiconductor product. An overcompensating agent is incorporated in the semiconductor in a restricted or limited region which is less than the entirety of the semiconductor body. The semiconductor is desirably of amorphous silicon. The undesired contaminant is a p acceptor and the compensating dopant is an n donor. Alternatively, the undesired contaminant can be an n donor and the compensating dopant can be a p acceptor. Typical p acceptors are residual boron and typical n donors are phosphorous. The compensation takes place over the range from about 1 to about 25% of the maximum thickness of the region of compensation. The compensating dopant is present in a limited amount ranging from about 1 part to about 50 parts per million.

  • Directed energy conversion of semiconductor materials
    Patent number: 4675467
    Abstract: Directed energy conversion of semiconductors by the directed energy fusion of a selective region of a semiconductor layer to provide a conductive path through the layer. A conductive path is formed through a semiconductive layer through opposed electrodes by conversion of the semiconductive region, for example, by laser energy applied to change the structure in the region extending between the electrodes. The change in conductivity of the path is monitored and used to control the formation of the conductive path by controlling the directed energy source.

  • Multi-electrode ion generating system for electrostatic images
    Patent number: 4675703
    Abstract: An ion generator for the formation of electrostatic images includes two electrodes (a "control electrode" and a "driver electrode") at opposite faces of a solid dielectric member which are electrically actuated to form ions in an air region adjacent the control electrode; a third, "screen" electrode; and an additional, "deflection" electrode, which together with the screen electrode modulates ion flow to an imaging surface. Ions of a given polarity are attracted toward the imaging surface by an accelerating field resulting from a direct current potential of the control electrode. The screen electrode is maintained at a screen potential to control passage of ions through one or more apertures therein, while a further, deflection potential applied to the deflection electrode provides an additional level of control over the size, shape and location of the resulting electrostatic images.

  • Gasification of fluids
    Patent number: 4660740
    Abstract: Method and apparatus for the gasification of liquids employing a separable pressure vessel which is easily dismantled for cleaning. The pressure vessel is charged from a gas source and provided with a relief valve that prevents the charging pressure in the vessel from exceeding a maximum pressure. Gas is introduced into the pressure vessel through a sparging orifice with an end that is also easily removable for cleaning. The pressure vessel has an outlet employing a single piece dispensing lever which includes not only ribs for opening the valve at the base of the pressure vessel but also an integrally molded restoring spring which has a special configuration for consolidating many of the functions which required separate pieces in the prior art.

  • Suspension of objects
    Patent number: 4651961
    Abstract: A longitudinally extending, or extendable, member is pivotally positioned within a housing. The member includes a protuberence at the pivot position to facilitate the pivoting of the member outwardly from the housing into a position for receiving an item that is to be suspended by the member. In accordance with one aspect of the invention, the housing is a frame with a rectangular opening that receives the longitudinally extending or extendable member. The latter desirably has a rectangular cross section in its longitudinal direction and is similar in its rectangularity to that of the opening in the housing within which it is pivotally positioned. In accordance with another aspect of the invention, a plurality of nested members are includable within the housing at the pivot position. In one form of nesting, a central member is bridged by adjoining legs which are in turn joined by the bridge.

  • Snowplow blade with spring-loaded edge flaps
    Patent number: 4635387
    Abstract: A snowplow with a blade having a lower edge to which several spring flaps are hingeably linked. Reset springs retain the spring flaps in their working positions, and return the spring flaps to their working positions after having been deflected. To prevent overload of the reset springs, each is supported to be movable in the same sense as the pivoting direction of the associated spring flap, so that the increase in spring force, while the spring flap is being deflected, is at least partially counteracted.
