Abstract: Abstract:        The present invention relates to an improvement in a device for controlling the position of a visual display cursor.  The device is movable on a surface having a pattern of relatively light and dark areas separated by edges and optically senses the motion of the device on the surface relative to two non-parallel axes so as to produce signals which represent a direction of motion for the cursor.  The device includes a unit for optically sensing motion on any random surface pattern with edges.  The unit is comprised of a plurality of prechargeable photon sensors disposed in a row along each axis, and a unit for periodically sensing the presence of an edge in at least one preselected portion of each row of sensors to define a sensor state for each axis to each period.  A comparator is provided for comparing successive sensor states for each axis to determine if movement has occurred relative to each axis.

Abstract: LASER WELDING OF SANDWICH STRUCTURES            ABSTRACT     A process is disclosed for bonding multi-layer sheet struc-ture by using controlled depth laser welding.  The laser energy may be applied in stages, whereby the inner sheets are first welded together and, the outer sheets are then joined thereto. The sheets are thereafter expanded to form the desired struc-ture.  Although the laser energy may be varied to control the depth of penetration, one embodiment utilizes a shield material to be applied between two sheets to prevent the laser energy from penetrating and joining the two sheets together.  Similarly, shields may be used to control the width of the laser weld.

Abstract: ABSTRACT OF THE DISCLOSURE         Process for copolymerization of vinylpyrrolidone and maleic anhydride in the presence of organic solvent, catalyst and between about 0.1 and 1.0 weight % water.  The use of small controlled amounts of water in an otherwise anhydrous process has a significant influence on the molecular weight of the resulting poly(vinylpyrrolidone-maleic anhydride) copolymer product.  In general the molecular weight of the copolymer is inversely propor-tional to the weight of water added.  Hence copolymers of varying molecular weights can be made by varying the amount of water used.

Abstract: ABSTRACT      A microwave apparatus for generating plasma afterglows for stripping  and/or  etching  of  photoresist  and  semiconductor material at a sufficiently high rate to allow single wafer processing in a fully automated reactor.  The apparatus includes a stripping/etching chamber for plasma afterglow stripping of photoresist and selective isotropic etching of semiconductor material,  such as polysilicon and silicon nitride,  using a variety of etchant compositions which form reactive species in a plasma.   In addition,  the apparatus may be employed for anisotropic etching for semiconductor material by decoupling etchant generation from ion production and acceleration by using two plasma sources, i.e., microwave power and radio frequency (RF) power.  Anisotropic etching is carried out in an etching chamber which subjects, in situ, a plasma afterglow to RF power and which is designed to operate in the reactive ion etch mode.

Abstract: ABSTRACT OF THE DISCLOSURE     A liquid flow regulator has a housing including an axial bore, an inlet, an outlet and a plurality of axial grooves opening endwise of the inlet and laterally of the housing into the bore.  The grooves, which have different axial lengths, taper axially so that the cross-sectional area of each groove gradually decreases from the inlet to nothing at a point where the groove merges with the bore.  An elastomeric stock fits within the bore.  A plunger for expanding the sock radially outward into sealing engagement with the housing adjacent the bore is axially movable within the bore.  Flow through the grooves and the bore is regulated by the axial position of the plunger and the minimum cross-sectional area of the tapered,  axial grooves at the axial location where the sock seals the bore.  Axial adjustment of the plunger sequentially opens and closes passge from the grooves through the bore to the bore outlet.  The upper end of the plunger is provided with threads for engagement with internal threading in a passageway so that rotation of the plunger adjusts its axial position for control of the flow.  The connection between the plunger and passageway threads is flexible so that the threads can be flexed out of engagement with each other when it is desired to axially and non-rotatively move the plunger to quickly place the regulator in a fully open or fully closed condition.
