The apparatus is capable of rapidly and accurately removing electronic components particularly those having axially extending leads, from a bulk storage supply, forming the leads into the parallel spaced configuration necessary for insertion into a P.C. board, advancing the lead-formed component into a position within the P.C. board stripping the component from the insertion mechanism and reloading a further component into the insertion mechanism.

Abstract: An apparatus for removing staples from paper, card and like sheet-form material is disclosed. The apparatus includes an anvil which deflects downwardly the leading end portion of a sheet inserted into the apparatus. A staple in the incoming sheet abuts against a tongue which causes the tongue to pivot rearwardly. The tongue is then moved towards the anvil to indent the paper adjacent the staple and orient the staple against the front face of the tongue. Next, the tongue is returned to a vertical position and the staple is pressed upwardly into a relieved portion of a rotary knife. The knife then slices off the top of the staple and removes the sliced off portion. Remaining portions of the staple are stripped from the paper as it is withdrawn from the apparatus.

Abstract: A process for producing VLSI (very large scale integrated) circuits employs techniques of self-aligned gates and contacts for FET devices and for both diffused conducting lines in the substrate and polysilicon conducting lines situated on isolating field oxide formed on the substrate. Mask alignment tolerances are increased and rendered non-critical. The use of materials in successive layers having different etch characteristics permits selective oxidation of desired portions only of the structure without need for masking and removal of selected material from desired locations by batch removal processes again without use of masking. There results VLSI circuits having increased density and reliability.

Abstract: A MESFET is fabricated using a self-aligned gate process. This process uses a vertical (anisotropic) etch to self-align the gate and source/drain. The vertical etch, in conjunction with a two-level insulator, creates a barrier between the gate and source/drain, so that when metal is deposited and reacted, and any excess removed, the gate is self-aligned with the source/drain, and contacts to the source/drain and gate are well isolated. The alignment obtained by this process is advantageous in that series channel resistance is reduced, and a more compact structure is attained for improvement in packing density.

Abstract: Gates of individual devices on a slice are connected through a resistance to the device substrate, and through the same resistance to other device gates.

Abstract: Solid state electronic devices are optically monitored during fabrication to detect hot spots which are indicative of faulty operation.

Devices are accepted, rejected, or further processed in response to the monitored fluorescence.

Abstract: A method is described for positioning the variable threshold region of a memory transistor by a predetermined distance from the drain and source regions. The method includes providing openings in the dielectric material over the substrate at the same time or in one mask step for the variable threshold region and the drain and source regions. A mask is positioned over the variable threshold region opening at times the drain and source regions are formed. The variable threshold region is subsequently formed by growing thin oxide and a layer of nitride thereover. Both sides of the variable threshold region have a fixed threshold region between the respective drain and source which is controlled by a common gate electrode. The invention overcomes the problem of providing additional space for alignment tolerances between the variable threshold region and the drain and source regions.

Abstract: Apparatus for placing coils and phase insulation in the slots of a dynamoelectric machine stator core member includes a core member loading and unloading station, a coil and phase insulation placing station, a preliminary end turn forming station, and a coil drifting station. An unwound core member at the loading/unloading station is loaded in mounting apparatus on a transfer arm which transfers the core to the placing station where coils and phase insulation are placed in the core member slots. The core is then transferred by the transfer arm to the preliminary end turn forming station where the end turns of the coils are formed away from the bore of the core member. The core member is then transferred by the transfer arm to the drifting station where the coils are drifted into the slots. The transfer arm ultimately transfers a fully wound core back to the loading/unloading station where the wound core is unloaded from the transfer arm and then inverted.

Abstract: A precision resistor using a resistance metal film etched into a long serpentine strip cemented to a substrate. This substrate is a composite of rigid materials and plastics. The composite thermal coefficient of expansion of the substrate is given a non-linearity which in turn induces a stress related non-linear resistance change in the cemented film when the temperature changes. This stress-induced non-linear change is of approximately the same shape as the inherent non-linearity of the resistance versus temperature of the metal film, but opposite in polarity, over a wide range of resistor operating temperatures. Over the range, a much closer approximation to complete temperature compensation is obtained than previously.

Abstract: A drafting tool is provided to assist in making parallel lines which can be horizontal, vertical or at any angle. The tool has two legs pivoted together and at least one of said legs carries a bar spaced above the drafting paper. The bar carries markers in the form of sharpened metal pins that indent drafting paper, or in the form of writing tips that leave a mark on paper. The bar is resiliently held, and when manually pushed against the drafting paper, the pins indent or the writing tips mark the paper. The draftsman then uses a straight edge to draw lines through the indicia thus made. The pins and writing tips are preferably uniformly spaced in a straight line and the spacing between indicia on the drafting paper with respect to a horizontal or vertical line are variable and are determined by the selected angle between the two legs. Suitable graduations at the pivot can advise the user of the pivot angle to select to obtain the proper indicia spacing with respect to a horizontal or vertical line.
