Abstract: Abstract:    There is provided a method of fabricating a semi-conductor device wherein in a bonding surface of a silicon substrate of n-type conductivity are formed recesses having each a bonding surface of a higher order plane index than that of the bonding surface of the silicon substrate, and the substrates are bonded together with an aluminum solder so as to decrease a forward voltage drop FVD.  After forming the recesses but prior to the bonding with the aluminum solder, phosphor is diffused into a region ranging from the bonding surface to a depth of 20 microns, thereby further decreasing the forward voltage drop FVD.

Abstract: TWINE-WRAPPING MECHANISM FOR A                      LARGE ROUND BALER                 Abstract of the Disclosure An automatic twine-wrapping mechanism for a large round baler.  The mechanism comprises a twine dispensing mechanism for dispensing twine into the bale-forming chamber of the baler, a reversible hydraulic drive means for cycling a twine arm of the dispensing mechanism back and forth in front of the chamber, a twine wrapping control mechanism for initiating a twine wrapping cycle by sensing the growth of a bale to a predetermined diameter, by automatically actuating a pump drive means for driving a hydraulic pump and by positioning a hydraulic control valve to condition the hydraulic drive means to cycle the twine arm and for terminating a twine wrapping cycle by deactivating the hydrau-lic drive means following the wrapping of twine around the bale.          The twine is automatically severed by a twine cutter responsive to the movement of the twine arm following completion of the wrapping of the twine around the bale.  The baler operator actu-ates a bale ejection mechanism following the cutting of the twine.  Following bale ejection, the twine wrapping cycle is terminated by the twine wrapping control mechanism sensing that the bale chamber is empty.  The baler is now ready to begin the formation of another bale therein.    Also, the twine arm includes a tubular guide and guide support, which in conjunction with a twine tensioner of the twine dispensing mechanism enables simplified threading of twine through the dispensing mechanism.

Abstract: ABSTRACT Apparatus for feeding a combustion chamber under elevated pressure comprises first and second serially connected bins, each having an inlet through which raw coal may be supplied and an outlet through which the coal leaves the bin.  The outlet from the first bin (relative to the flow direction of the raw coal) supplies raw coal to the inlet of the second bin.  A mill for processing the raw coal is provided, such mill having an inlet connected to the outlet from the second bin and the mill being adapted to pulverize the raw coal to fines or dust according to the requirements of the combustion chamber.  A further inlet to the mill is provided for supplying a carrier gas for the pulverized coal and outlet means are provided on the mill for expelling the pulverized coal and carrier gas mixture from the mill.  Conduit means are provided for conveying the mixture under pressure to the combustion chamber. The inlet of each bin is provided with a pressure-tight shut-off member and the first bin is provided with a vent pipe having a shut-off valve therein.  The invention eliminates the need for an intermediate storage facility between the mill and the combustion chamber and the pulverized coal may be fed directly from the mill to the combustion chamber under elevated pressure.

Filed: 1983-10-26
Granted: 1988-06-28
Abstract: ABSTRACT OF THE DISCLOSURE           A description is given of a method for the combined production of ammonia and urea.  An ammonia-synthesis gas, consisting mainly of hydrogen, nitrogen and carbon-dioxide, is subjected to pressurized washing, at temperatures equal to ambient temperature at the most, for the removal of acid contaminants, more particularly carbon-dioxide, with a physically acting solvent.  The charged solvent is partly expanded for gassing out co-absorbed inerts, is then regener-ated without pressure, is returned to the pressurized wash, and the carbon-dioxide released during regeneration is used to synthesize urea.  In order to be able to release this carbon-dioxide, in an energy-saving manner and pre-compressed to the urea installation, it is proposed that the pressure over the charged solvent be brought, after partial relief, to an intermediate value, that the charged solvent be heated for partial gassing out of carbon-dioxide, that the solvent thus partly regenerated be subjected to the final pressureless regenerating stage, and that the carbon-dioxide gassed out during heating be cooled and be released at the intermediate pressure.

The apparatus of the present invention is a safe and convenient cycler apparatus for performing peritoneal dialysis in either home or clinical environment.  The apparatus provides a stable base (52) by storing dialysate at a relatively low position.  Tubing administration set length is reduced to a minimum by the use of indivi-dual, separated valves (36, 38, 40, 42, 44) and by the elimination of redundant, duplicate tube sections.          Administration set complexity is reduced by the use of a conventional design dialysate container (46) for heating and weighing of an infusing dialysate dosage.          The apparatus (50) allows for gravity feed to a patient with an optional capability of adjusting the pressure head for the gravity feed.

Abstract: TUNING ARRANGEMENT FOR INTERFACING                 CREDIT CARD-LIKE DEVICE TO A                         READER SYSTEM     Abstract A circuit for maximizing power transfer from a station to an interactive memory card via a capacitive interface.  A reader system in the station generates an ac signal which provides operating power that is transferred to the card through the capacitive interface formed when the card is placed against a window on the station.  The ac signal from the station is directed through a series resonant circuit to the card.  The capacitive interface between the station and card make up the capacitive element of the resonance circuit while the series combination of the secondary of a transformer and an electrically variable inductor form the inductive element.          Use of the variable inductor allows the station to tune the circuit to resonance and cancel the capacitive element, thereby maintaining maximum power transfer to the card.
