Abstract: ABSTRACT A diode has at least a first region and a second region with the regions abutting each other to form a junction therebetween and with the first region being made of an amorphous alloy including silicon and fluorine.  Such a diode finds particular usefulness in closed cells in a ROM or in a EEPROM device having a memory circuit at each cross over point of a conductor of a first group of conductors in a memory matrix extending in a first direction over a conductor of a second group of conductors extending in a second direction traversing the first direction.  The first group of conductors is insulated from the second group of conductors and each memory circuit is coupled to and between a pair of crossing over conductors at one of the cross over points and includes a memory region and the diode.  Preferably, the amorphous alloy also contains hydrogen and such alloy is a-Sia:Fb:Hc, where a is between 80 and 98 atomic percent, b is between 0 and 10 atomic percent and c is between O and 10 atomic percent.  The first and second alloy regions of can be oppositely P and N doped.  Alternately, one of the regions can be a metal, metal alloy or a metallic like material to form a Schottky barrier with the other region or MIS junctions can be utilized.

Abstract: Abstract of the Disclosure:            Method of extracting liquid hydrocarbons from oil-containing stone  or  sand,  wherein  the  oil-containing  stone  or  the oil-containing sand undergoes hydrogenating,  low temperature carbonization in a reactor at temperatures of 450 to 520°C and a pressure of approximately 50 bar through the action of carbon monoxide, hydrogen and steam, and wherein the hydrocarbons are separated   from  the  resulting  gaseous,   low  temperature carbonization  mixture.   The  low  temperature  carbonization mixture from the reactor is cooled in a first separation stage to a temperature of approximately 350°C to condense the less volatile hydrocarbons.  The separated, liquid phase is fed to a solids separator and placed in contact with a circulating gas of carbon dioxide and a C6/C7 hydrocarbon fraction.  The low temperature carbonization mixture containing uncondensed gases and more volatile hydrocarbons are washed in a second sepa-ration stage with water and cooled to approximately 250°C.  Gas containing hydrogen separated from the volatile hydrocarbons is fed at least partly to the reactor again.  Carbon monoxide is obtained from the solids through the action of carbon dioxide, contained  in  hot,  combustion  gases.   This  carbon  monoxide together with carbon dioxide of the combustion gases is fed to the reactor.

Abstract: METHOD AND APPARATUS FOR PREFETCHING INSTRUCTIONS            A B S T R A C T      Method  and  apparatus  for  prefetching  instructions  for  a pipelined central processor unit for a general purpose digital data processing system.   A table is maintained for purposes of predicting  the  target  addresses  of  transfer  and  indirect instructions based on past history of  the  execution of  those instructions.  The prefetch mechanism forms instruction addresses and  fetches  instructions  in  parallel  with  the  execution  of previously fetched instructions by a central execution pipeline unit  of  the  central  processor  unit.    As  instructions  are prefetched, the transfer and indirect prediction (TIP)  table is checked to determine the past history of those instructions.  If no  transfers  or  indirects  are  found,  the  prefetch  proceeds sequentially.   If tranfer or  indirect  instructions are  found, then the prefetch uses information in the TIP table to begin fetching the target instruction (s).   The purpose of the prediction of target addresses is so that in  the  usual  case  instructions  following  a  transfer  can  be executed  at  a  rate  of  one  instruction  per  pipeline  cycle regardless of the pipeline depth or the frequency of transfers.          Instructions are fetched two words at a time in order that the instruction fetch unit can stay ahead of the central execution pipeline.   An  instruction  stack  is provided  for  purposes  of buffering double words of instructions fetched by the instruction fetch unit while waiting for execution by the central execution pipeline unit.   The TIP table is updated based upon the actual execution of instructions by the central execution pipeline unit, and  the  correctness  of  the  TIP  table  predictions  is  checked during execution of every instruction.

Abstract: ABSTRACT OF THE DISCLOSURE      The invention is an  improved wrapper construction for smoking articles such as cigarettes resulting in a reduced tendency to ignite combustible materials accidentally or carelessly coming into contact with the lit cigarette.  The wrapper constructions and smoking articles of the invention have a specially designed structure which causes a cigarette to go out quickly when in contact with a substrate, including many commonly-encountered substrates made of combustible materials.  This structure is characterized by a Burn Mode Index ("BMI") as defined for the wrapper of between about 1.5 cm-1 and 5.0 cm-1 for a single wrap embodiment.  For an alternative double wrapped embodiment, the outer wrap will have a BMI in the range of from about 2.0 cm-1 to about 40 cm-1 depending on the BMI of the inner wrap which may vary between about 0.1 cm-1 to 4.0 cm-1.  The preferred amount of burn promoter is at least about 15 mg anhydrous potassium citrate per gram of bone dry paper or stoichiometrically equivalent amounts of other burn promoting salts. Preferred substrate embodiments include paper made from flax or other cellulosic fibers, treated with elevated amounts of an alkali metal burn promoter such as alkali metal salts of carboxylic acids, especially potassium salts.  In contrast to other attempts, these results are obtained without a significant sacrifice of desired taste and smoke deliveries, for example, without unacceptable increases in puff count or significant increases in delivered tar and carbon monoxide. Wrapper constructions and smoking articles of this invention may be manufactured using conventional cigarette paper processes and equipment.
