A doped polycrystalline silicon layer is then formed through the mask covering the base region and making ohmic contact thereto. An insulating layer is formed over the polysilicon layer. The mask is removed from those regions designated to be the emitter and collector reach-through regions.

The spreading device includes a pair of lower grip members movable away from each other on a horizontal base, and a pair of upper grip members vertically aligned with the lower grip members, respectively, and displaceable away from each other.

Abstract: A method of making an element for sensing the presence of nitrogen dioxide gas in the environment. The element is formed by heating a film of an electrically non-conductive polyaromatic polymer to a temperature sufficiently high to pyrolyze the polymer and render the polymer semi-conductive. The pyrolyzed film is mounted on an electrically non-conductive base. Electrical leads are attached at spaced locations to the film and are connected in an electrical circuit with a signalling or control mechanism. The presence of nitrogen dioxide gas will cause a change in the electrical characteristics of the film to thereby activate the mechanism. A heating element can be associated with the base to insure constant temperature and humidity conditions.

Abstract: In my co-pending application Ser. No. 949,811 of Oct. 10, 1978, now U.S. Pat. No. 4,188,718 I disclosed an improved device for "girdling" trees. That device effectively removes a complete circular band of bark and all that underlies the bark to the central portion of the tree so that fluid cannot pass from the root system of the tree to the upper portion of the tree whereby, with the elimination of such fluid transmission, the tree dies. In many areas, such girdling is practiced widely as a method of improving the ecology of the area for the dead trees are readily removed by being pushed over by a bulldozer. This invention relates to a construction of such a girdling device whereby the bark or other material caught between the cutting element during girdling can be readily removed.

The cutting line length is always extended to this predetermined maximum length irrespective of the length of cutting line being lost to wear or breakage. The line feeder mechanism is actuated by sensing an operating condition of the head, e.g., angular velocity of rotation.
