A magnetoresistive effect element having a large magnetoresistive change with a small magnetic field, and a memory element using the same. A semiconductor film to provide a window for excitation light is arranged on a substrate via a buffer layer. Another semiconductor film and a nonmagnetic metallic film (or a nonmagnetic insulating film) are arranged on the semiconductor film successively. A magnetic film having a square magnetization curve is arranged on the nonmagnetic metallic film (or a no...

A drill bit having a bit body intermediate a shank and a working face having at least one cutting insert. A bore is formed in the working face co-axial within an axis of rotation of the drill bit. A jack element is retained within the bore by a retaining element that intrudes a diameter of the bore.

A building element for the production of internal and external walls, parapets, fences, sheathings, and the like includes two flat boards joined by bars, and tongue elements. The dimensions of the elements are coordinated to permit many different ways of assemblage of the flat boards in order to form prefabricated building elements which are designed for specific purposes.

An electrochromic element comprising a composite cell composed of a lamination of a plurality of unit cells, at least in partial registry with one another; each of said unit cells having a pair of transparent flat electrodes at least in partial registry with one another and an electrochromic material filling a space between said transparent electrodes, and a transparent substrate for supporting said composite cell.

This invention relates to universal connecting elements for removably joining together frame members such as posts, braces, stays or the like. The same connecting element is used at all corners and/or main points of the frame structure, and consists of two open-ended sleeves oriented at 120.degree. to one another, and a third sleeve open at both ends thereof which extends in one direction only from a plane defined by the forwardmost faces of the two sleeves, the third sleeve being oriented at 90...

A structural element for use as a component part of a building, comprising a pair of parallel elongated rectangular side plates having opposite surfaces spaced a distance apart from each other and connecting means disposed between the side plates so as to rigidly connect the side plates in the spaced-apart relation. The connecting means can be a single elongated rectangular flat plate having its opposite longitudinal side edges fixed to the opposite surfaces of the side plates along the center l...

A logic element, particularly a bipolar gate circuit for an LSI-circuit, employing a pair of Schottky-diodes, a pair of resistances and a transistor, with the diodes, connected in high resistance direction, to respective inputs, the other sides of the diodes being connected in common to a first resistance and to the base of the transistor, with said first resistance being operatively connected to a reference potential, said second resistance connecting the collector of the transistor, and the co...

An antenna element for use in the nose section of a small missile is disclosed. The antenna element includes a ground plane and a pair of end fed radiating elements, the free ends thereof being fastened to ground plane. With such arrangement the antenna element fits compactly within the nose section and the ground plane provides a heat sink and structural support for the radiating elements.

A bimetallic element in which a bimetallic strip of two bands of different metals is wound helically into an elongated body, said body having in its center a free space, the diameter of which is smaller than the thickness of the bimetallic strip and preferably is essentially zero. By winding said elongated body into a helical spring, the outer diameter of which is substantially greater than the outer diameter of the elongated body, an element is obtained that can be used as a thermostatic actuat...

A fusible element for a current limiting fuse includes two silver ribbons, each provided with a plurality of holes spaced apart along the length thereof which define fusible points of reduced cross sectional area, one of these ribbons including a conventional "M" spot consisting of a body of low melting temperature alloy such as tin-lead solder, in intimate contact with the silver ribbon. One end of each of the silver ribbons is joined to a respective end of a centrally disposed tin wire element...
