Abstract: ABSTRACT     A low pressure process for making amorphous semiconductor alloy films and devices at high deposition rates and high gas conversion efficiencies utilizes microwave energy to form a deposition plasma.  The alloys exhibit high-quality electronic properties suitable for many applications including photovoltaic and electrophotographic applications.    The microwave energy and reaction gases form a glow discharge plasma within a reaction vessel to deposit an amorphous semiconductor film from the reaction gases onto a substrate.  The reaction gases can include silane (SiH4), silicon tetrafluoride (SiF4), silane and silicon tetrafluoride, silane and germane (GeH4), silicon tetrafluoride and germane, germane or germanium tetrafluoride (GeF4).  Hydrogen (H2) can also be added to the reaction gases.  Dopants, either p-type or n-type can also be added to the reaction gases to form p-type or n-type alloy films, respectively.  Also, band gap increasing elements such as carbon or nitrogen can be added in the form of, for example, methane or ammonia gas to widen the band gap of the deposited alloys.

Abstract: ABSTRACT A reversible typing ribbon cartridge has two pairs of pinch roll pairs for moving the ribbon in the direct and inverted positions respectively. When the cartridge is off the typing machine both pinch pairs are engaged with the ribbon, but as the cartridge is installed, a rod penetrates into the car-tridge and disengages the pinch pair in the following position while drives engage the ribbon spool and the pinch pair in the leading position.  According to the invention, since only the leading pinch pair engages the ribbon, whether the cartridge is being operated in the direct or inverted position, squeezing and consequent degradation of the ribbon is minimized.

Abstract: ABSTRACT           DRILL BIT SHARPENING DEVICE       A sharpening device, particularly useful for sharpening tools having two identical cutting edges such as drill bits, comprised of a jig for holding a drill bit used with an adjustable grindstone and a pivot arm retaining means.  The jig has a clamp means for releasably retaining a tool or drill bit in it, and a frame.  The frame is connected to the clamp means, and typically carries first and second pivot arms which are symmetrically disposed at an angle to the clamp axis.  The first pivot arm is placed in the pivot arm retaining means of the support where the jig can rest in a first rest position in which the clamp axis extends forwardly to intersect a grinding face of a grind-stone carried in the support, at a predetermined lateral angle of A1 thereto.  In addition, by inverting the jig, it can rest on the support, in a second rest position inverted from the first position, in which the second pivot arm rests in the pivot arm retaining means with the clamp axis extend-ing forwardly to intersect the same grindstone grinding face at an equal lateral angle of A2 and at the same intersection point on the clamp axis.  Thus, tools such as drill bits, can have each of their cutting edges accurately and identically sharpened, with the points centered and the cutting edges of the same length and angle accurately obtained during sharp-ening, basically by simply inverting the jig holding the bit.

Abstract: APPARATUS FOR AUTOMATIC COIL FEED                    ABSTRACT OF THE INVENTION Apparatus for automatic coil feed of a sheet metal stock strip in progressive dies for punch press die operations which adjust the length of stock strip being intermittently fed to the punch press die while the press is operating. The apparatus comprises feed apparatus for feeding a predetermined length of stock strip to the punch press die which feed apparatus normally operates at a preset feed length. There is a control for maintaining the correct feed length of the stock strip being intermittently fed into the punch press die and includes a correction arrangement operable to momentarily change the preset feed length to supply a correcting length of stock strip to the punch press die. There are two longitudinal arrays of registration openings in the stock strip. A first probe mechanism operable when the stock strip stops to detect non-registration of a registration opening in one array resulting from overfeed of the stock strip and a second probe mechanism operable when the stock strip stops to detect non-registration of an opening in the other array resulting from underfeed of the stock strip. Upon detection of underfeed or overfeed of the stock strip, switches activate the control mechanism to shorten the length of stock strip fed to the punch press die or lengthen the length of stock strip fed to the punch press die as the detection case may be while the press is in an operating mode.
