Abstract: Abstract of the Disclosure core assembly is formed by fabricating a first core, molding a destructible plastic layer around the first core, and molding a second core around the plastic layer.  The plastic layer is interlocked with an irregular outer surface of the first core, and the second core is interlocked with an irregular outer surface of the plastic layer.  The core assembly can be used for casting engine cylinder heads to eliminate the need for gluing cores together and the accompanying formation of fins within fluid conducting passages.

Abstract: AMORPHOUS SEMICONDUCTOR MEMBER                     AND METHOD OF MAKING THE SAME     Abstract of Disclosure An amorphous semiconductor member includes an amorphous semi-conductor material which is formed in a solid amorphous host matrix having structural configurations which have local rather than long-range order and electronic configurations which have an energy gap and a large electrical activation energy, and, added to the amorphous host matrix, a modifier material having orbitals which interact with the amorphous host matrix and form electronic states in the energy gap which modify substantially the electronic configurations of the amorphous host matrix for reducing substantially the activation energy thereof and, hence, increasing substantially the electrical conductivity of the semiconductor member substantially at room temperature and above. The amount of addition of the modifier material controls the range of electrical conductivity, and can be greater than dopant amounts usually used for doping semiconductors. The amorphous host matrix is normally of intrinsic-like conduction and the modifier material added thereto changes the same to extrinsic-like conduction. In one form of the invention, a primarily lone-pair amorphous semiconductor material having orbitals is utilized wherein the orbitals of the modifier material interact with the orbitals of the amorphous host matrix and form the electronic states in the energy gap. In another form, a primarily tetrahedral bonding amorphous semiconductor material is utilized wherein the orbitals of the modi-fier material, added primarily in a non-subtitutional manner, interact with the amorphous host matrix and form the electronic states in the energy gap. In a further form, an amorphous semiconductor material containing boron is utilized wherein the orbitals of the modifier material interact with the amorphous host matrix and form the electronic states in the energy gap.

Abstract: HIGH SHEET RESISTANCE STRUCTURE FOR HIGH DENSITY          INTEGRATED CIRCUITS          Abstract A high sheet resistance structure for high density integrated circuits and the method for manufacturing such structure is given.  The structure includes a silicon region separated from other silicon regions by a dielectric barrier surrounding the region.  A resistor of a first conductivity, for example, N type, encompasses substantially the surface of the silicon region.  Electrical contacts are made to the resistor.  A region highly doped of a second conductivity, for example, P-type, is located below a portion of the resistor region.  This region of second conductivity is connected to the surface.          Electrical contacts are made to this varied region for biasing purposes.  A second region within the same isolated silicon region may be used as a resistor.  This region is located below the buried region of second conductivity.          Alternatively, the described resistor regions can be connected as transistors.  This allows the formation of a standard masterslice which can be personalized at a late stage in the manufacturing to either resistors or transistors in all or a portion of the standard regions.

Abstract: Abstract A micro processor controlled user programmable communications multiplexer subsystem (herein referred to by the symbol PCS) capable of transmitting and receiving data on any one or more of 32 communi-cations lines simultaneously. Each line may be dynamically assigned to a variety of communication characteristics, such as line speeds, character lengths, synchronous, or asynchronous operation, and code structures as well as protocol selections.     The  system of the invention provides the capability for the user to write his communications programs using novel operations commands that provide code structure and protocol independence as well as com-munication line independence. Various hardware features and queuing techniques are employed in order to maintain high transmission rates.     Variable line scanning in the Teleprocessing Time Division Multi-plexer of the PCS is programmably permissible; i.e., the time base for line scanning is fixed and is a multiple of the communication line rate, although the actual line to be scanned is programmably variable.  The program ability is provided by a continuously scanned storage array which contains physical line addresses of the time division multiplexer. The scanning mechanism, while running, prioritizes the transmit buf-fer servicing of the individual lines.

Abstract: 30.3.1979                                     PHD. 78-029. ABSTRACT Coding and artifact-free decoding of objects.     A method of coding and decoding of objects by means of a large number of point-like radiation sources which are sub-divided into two groups. In two coding steps, two recordings are made of an object to be irradiated. A first recording is made on a first recording medium with a first radiation source distribution. A second recording is made with a second radiation source distribution which is determined by the autocorrelation function o-f the first distribution. In the second radiation source distribution, the source which is determined by a function value in the origin of the autocorrelation function is omitted. In a first decoding step, the first recording is decoded with a-point image function of the first radiation source dis-tribution. In the second decoding step, the second re-cording is subtracted from the decoded first recording, so that an artifact-free image of the object is produced.
