A shirt with a "built in" collar is provided. The shirt may be prepared from either one or two sections of fabric. In either case the neck collar portion of the fabric is specifically cut so that upon assembly of the shirt a full collar portion thereof may be formed by simply folding back the fabric around edges of the neck opening.

A method and apparatus for fabricating an aperture of predetermined cross-sectional area in an orifice plate for use in a non-contact printer, includes the steps of fabricating in the orifice plate an aperture of cross-sectional area no less than the predetermined cross-sectional area, flowing an electrolytic deposition solution under pressure through the aperture, applying a constant frequency stimulating disturbance to the stream of electrolytic deposition solution emerging from the aperture, ...

Photolithographic techniques are employed to fabricate hemispherical or semicylindrical microlenses on the end surfaces of optical fibers. The power coupling efficiency between junction lasers and fibers is thereby significantly increased.

A laminated, cylindrical, metal screen or molding element for vacuum perforation of plastic film or sheets, comprising two or more relatively thin cylindrical metal screens, each having a predetermined inside and outside diameter and each having a plurality of openings or holes therein of a predetermined size and geometrical shape, and said relatively thin screens stacked and bonded together, diametrically one inside the other thereby providing a screen of a desired thickness and a desired hole ...

In the manufacture of a modular building panel having a three-dimensional welded wire matrix, the matrix is comprised of a plurality of essentially identical truss-like matrix subunits which are assembled in a machine which includes means for periodically adjusting for the adverse effects of tolerance accumulation so that the matrix subunits may be fabricated in an essentially continuous array in which each subunit has a length within predetermined tolerance limits. A plurality of strips of pref...

A method of forming an integral rivet in a sheet element including providing cooperating male and female dies and an interposed sheet element, moving the male die toward the female die to draw an outwardly directed hollow boss. Continuing movement of the male die toward the female die to thin an annular region in the lower portion of the hollow boss by compression which establishes metal flow substantially entirely in the direction of the upper portion of the hollow boss. Continuing relative clo...

A turbofan mixer is fabricated from a structural panel of the variety including substantially planar first and second walls and a filler material sandwiched therebetween. The mixer includes at least one acute angle formed by bending the structural panel about a portion of the first wall, whereby the first wall forms the interior and the second wall forms the exterior of the angle. The first and second walls are protected from crushing and stretching proximate the apex of the angle during the ben...

A method of fabricating field effect transistors which includes control of threshold potential by an ion implantation limited to the active channel area. The active channel area is defined by a photoresist pattern. Ions are implanted into the exposed area in a concentration to achieve a desired threshold. Appropriate metals are deposited over the channel area to form a gate electrode. The photoresist is lifted off leaving the gate electrode in position over the channel area. If desired, a layer ...

The fabrication of a microcircuit by beam lithography requires an economic distribution of processing time between the high resolution portions of the exposure pattern and areas of much lower resolution. At least one ion beam provides the high resolution performance and at least one electron beam satisfies the lower resolution requirement. The beams are independently operable and are relatively inclined for substantial convergence at the substrate. The convergence is such that all beams can be s...

A method of fabricating FETs to reduce parasitics. Contact is made to the source and drain regions through a polycrystalline silicon runner which is aligned with the edge of the gate electrode. This is accomplished by providing a layer such as palladium over the gate electrode and depositing the polycrystalline silicon layer over the device. The polycrystalline silicon and palladium form a silicide which is then selectively etched leaving the remaining polycrystalline silicon aligned with the ga...
