Abstract: An apparatus and method for rolling metal matrix composite material is disclosed. The material is confined within an aperture in a frame member during the rolling process.

Abstract: A method and apparatus for laying a railroad track includes laying, in tandem, a series of pre-cast concrete slabs on a prepared track bed, the slabs being isolated from the bed, and from each other, by rubber isolation pads, and the slabs having cavities formed on the top faces. The rails are held above the slabs, in their proper location, by removable gauge beams having adjustment means to exactly locate the rails. Before filling the cavities with concrete the shoulder-pins, used to secure the rails, are located with their pin portions in the cavities by being removably secured to templates. The templates are held suspended above the slabs by being removably attached to a rail. The rails are used as guides after setting their exact gauge (separation), elevation and cant (angle of inclination) on the gauge beams, to determine the positions of the templates and shoulder-pins.

Abstract: A method of manufacturing an insulated gate field effect transistor has first and second impurity doping processes for forming source and drain regions. In the first doping process, an impurity is lightly doped in the source and drain forming regions in self-alignment with a silicon gate pattern and a field insulating film. Next, a heat treatment is conducted so that the side surface portions of the silicon gate pattern are converted into silicon oxide films having a predetermined thickness. Thereafter, the second doping process is conducted in which an impurity is heavily doped in each part of the source and drain forming region in self-alignment with the silicon oxide films and the field insulating film. Each of source and drain region manufactured by the method has a first part of low impurity concentration adjacent to a channel region and a second part of high impurity concentration positioned between the first part and the field insulating film.

Abstract: Using a process constructed in accordance with the teachings of this invention, a double recess, N+ ledge field effect transistor may be formed using a single masking step. Two layers of photoresist of differing types are formed on the surface of an N+ epitaxial layer. On the surface of these photoresist layers a layer of material which may be etched by reactive ion etching with freon but will not etch by reactive ion etching with oxygen is formed. A gate pattern is etched into this surface layer of material and the photoresist layers are selectively undercut to provide a pattern to etch the gate recess and the wide recess. A gate contact is then formed by perpendicular evaporation through the gate pattern in the surface layer of material. Thus the invention provides a process for forming a self-aligned double recess transistor using a single mask to form the gate, the wide recess and the gate recess, and another mask to form the source and drain contacts.

Abstract: Among the variety of bucket arrangements that are commonly available, several are specifically designed for ripping applications in materials that are extremely hard to penetrate. While these types of buckets are normally satisfactory in ripping hard, strong, brittle materials, their designs do not lend themselves to excavating and dumping weaker more plastic materials and thus exhibit little or no versatility. The bucket arrangement of the subject invention includes a first and second ground penetrating means that are selectively positioned on the bucket with respect to each other. The selective positioning allows sole engagement of either of the first or second ground penetrating means with the ground or simultaneous engagement of both penetrating means with the ground. Such an arrangement provides superior operation in a ripping capacity and yet the selective positioning of the first and second penetrating means also permits excellent operation in weaker or plastic materials.

Abstract: A fish hook having two hooks which are movably secured together to move in a scissors like fashion, a spring portion that can forcibly seperate the point and barb parts of the two hooks, and a trigger safety adaptation is disclosed. The two hooks are brought together parallel to each other then the spring portion is flexed to form an acute angle with the two hooks. In this position the two hooks will not seperate unless a force is introduced to change the angle of the spring portion and the two hooks. During fishing the force will be supplied by the fish biting and slightly tugging the bait. Once the fish hook is activated the two hooks forcibly seperate thereby catching the fish. The double hook design practically eliminates the chance of the fish getting loose by vigorous movements. To eliminate the chance of the fish hook being activated by the vigorous motion of casting and hitting the water surface a safety adaptation is devised.

Abstract: A fishing lure comprises a rotor having vanes causing relative rotation thereof about a hollow shaft. The rotor is retained on the shaft between a forward cylindrical head and a trailing conical member stationarily fixed to opposite ends of the shaft. The lure head is flat and contains bores trapping air when the lure breaks the water surface. The entrapped air gradually releases when the lure submerges and travels along the sides of the lure. The vanes project outward into the path of the air to produce a stream of bubbles that attracts fish. Notches are formed in the head to establish a rotative force in the lure that resists the tendency of the head, tail and shaft assembly to rotate with the rotor. The fishing line extending through the hollow shaft is thus prevented from twisting.
