Abstract: ABSTRACT OF THE DISCLOSURE         A surface oriented lateral bipolar transistor having a base of narrow width is fabricated by using a doped polycrystalline silicon layer as an ion implantation mask when implanting ions for the emitter and base regions. In forming the doped polysilicon mask, a first layer of dopant masking material is formed on the surface of a semiconductor substrate, a second layer of un-doped polysilicon is formed over the first layer, and a third layer of dopant masking material is formed over the second layer.  Portions of the second and third layers are removed and a dopant is diffused into the exposed edge portion of the second layer.  The third layer and the undoped portion of the second layer are then removed thereby leaving only the doped portion of the second layer on the first layer.

Abstract: DRIVE APPARATUS                   Abstract of the Disclosure Disclosed is drive apparatus especially useful for con-trollably displacing the carrier of a printer, the drive apparatus including a lead screw having laterally spaced apart and floating threaded followers thereon.  Intermediate the threaded followers are a first pair of preloaded springs which press the followers against the opposite flanks of the threads on the lead screw to thereby inhibit backlash intermediate the followers.  A second pair of springs are mounted intermediate a bracket, which is fastened to the carrier, and at least one of the followers for effecting coupling between the carrier and the follower while controlling backlash therebetween.  A pair of arms extend from the followers and are coupled to a restraining shaft in such a manner as to inhibit rotational movement of the arms (and thus the followers) while permitting motion of the followers in any perpendicular direction to the lead screw to accommodate runnout or eccentricity.

Abstract: ABSTRACT OF THE DISCLOSURE     This invention relates to a novel leg strengthening apparatus which is used for muscle development, exercise and rehabilitation.  The apparatus comprises an air reservoir, a valve to control the flow of air into and out of the reservoir, a cylinder in communication with the valve and an actuator which is secured to a piston within the cylinder.  The apparatus will produce isometric, concentric and eccentric contractions in a muscle and allows for differing velocities of exercise movement, which has not been possible to achieve with the prior art devices.  The apparatus is simple in design and is adaptable for home use.  It includes variable resistance and can provide maximum muscle strengthening ability in correlation to the strength curve  of the preselected muscle.  The apparatus achieves these objectives using no auxiliary fluid-supply source and is self-contained and safe to operate.  All these features in a single apparatus are not found in the prior art devices.

Abstract: ADJUSTABLE MACHINING SYSTEM AND IMPLEMENT THEREFORE                A B S T R A C T   A machine tool system having an adjustable implement mounted in a holder or chuck and moveably positioned relative to a moveable workpiece support, wherein implement adjustments are produced by controlled differential motion between the implement holder and an adjustment fixture on the workpiece support.The support is moved to engage the implement in the fixture, from which state further relative movement unlocks an implement clamp and produces a desired adjustment in the implement. Typical implement adjustment applications would include setting of a boring bar cutting radius (or setting of a measurement gauge dimension). The adjustments can be performed open loop based on prior calibration of implement adjustment versus extent of support motion, or closed loop wherein an initial cut (or measurement) is made by open loop implement adjustment with subsequent adjustments based upon a measurement made of the implements effective cutting (or measurement) dimension. Desired incremental changes in cut(or measurement) dimensions are then effectuated through corresponding incremental support motion. Closed loop measurement and adjustment iterations largely overcome implement dimension errors due to rechucking, thermal drifts, machine motion position offsets, implement or contact point phenomena effects, speed-related dynamic distortions, gradual implement/wear and implement/work-piece force compliance. These measurements for iterative adjustment can be made with manual or automated gauging systems, either separate or integral to the machine adjustable implement system. The implement adjustment mechanism can be provided with a substantial mechanical advantage to correspondingly increase accuracy in implement adjustment.

Abstract: ARTICLE FEEDING APPARATUS ABSTRACT OF THE DISCLOSURE    An apparatus for intermittently feeding a series of like articles along a path so as to present them in succession to a plurality of operation stations where operations are performed upon the articles in sequence. The apparatus is provided with at least a pair of spaced drums mounted on parallel axes and a one-piece sub-stantially non-stretchable belt passing around the drums. One of the spaced drums constitutes a driving drum and the other of the spaced drums constitutes a low inertia idler drum.     The driving drum is provided with a hub having a peripheral flange at one end thereof.  A cylindrical rim, providing axially aligned sprocket teeth about its periphery, is mounted about the hub with a first end in abutment with the peripheral flange of the hub. The other end of the rib has at least one notch therein and a spider, mounted on the hub, has at least one arm engagable in the notch of the rim to lock the rim with respect to the hub.  Means are provided to rotatably adjust the spider with respect to the hub so as to rotatably adjust the rim, and thus the sprocket teeth, with respect to the hub.  The low inertia idler drum is provided with a pair of spaced side plates fixed to a non-rotatable shaft. Opposed coaxial pairs of first roller bearing means are mounted on the side plates such that the axes thereof are substantially parallel to the axis of the non-rotatable shaft.  A sleeve is rotatably mounted around the first roller bearing means and opposed pairs of second roller bearing means having axes substanially perpendicular to the axis of the shaft bear against the peripheral edges of the sleeve to provide axial guiding for the sleeve.     The non-stretchable belt is of flexible material having non-stretchable elements embedded therein and running longitudinally of the belt so as to give the belt non-stretch characteristics.  Inwardly projecting driving teeth are provided along both edges of the belt.  The belt has seating elements of a shape to fit the articles regularly and accurately spaced along its length.
