Abstract: Abstract of the Disclosure Methods and systems for effecting a variety of elec-tronic funds transfer transactions are based upon the use of unit records containing preprinted non-machine readable data, pre-printed machine readable data, and manually entered data, and conversion of such records from negotiable instruments to docu-mentary evidence of the satisfactory completion of the trans-action.  By first automatically reading the encoded data on the unit record and incorporating transaction data and security information in messages transmitted from a terminal, a financial institution can verify the validity of the transaction, effect the transaction and return an authorization message containing both reference and transaction information for imprinting on the unit record.  The record then evidences the satisfactory com-pletion of the transaction, and no further document generation or handling are needed at the merchant and financial institutions involved.  The record is capable of usage as a conventional negotiable instrument if terminal facilities are inoperable or not available.

Abstract: DIGITAL COMPUTER             ABSTRACT OF THE DISCLOSURE          The architecture of a conventional digital computer, for example, a microprocessor, is modified by interposing a multiplexer, a logic array and a demultiplexer between the instruction register and instruction decoder.  The logic array "scrambles" the bits in each instruction code, however, if the program to be run is priorly encrypted with this "scrambling" in mind, it will run normally.  On the other hand, if the encrypted program is copied, the copied program will not run on an unmodified computer.

Abstract: LOW VOLTAGE ELECTRICALLY ERASABLE   PROGRAMMABLE READ ONLY MEMORY     Abstract An improved memory system is provided for charging and discharging a conductive plate such as a floating gate of a field effect transistor with a charge injector controlled by a low single polarity voltage pulse.  In the system of the invention, the conductive plate may be a floating gate of a field effect transistor which also includes first and second or dual control gates.  A single or double graded band gap layer, such as a silicon rich layer of silicon dioxide is disposed only between the floating gate and the first control gate forming a capacitor having a given capacitance with a larger capacitor disposed between the second control gate and the floating gate.  These cells or transistors may be used in an array for storing for long periods of time, on the order of 10 years or more, binary digits of information representing a 0 or a 1 depending upon whether a charge is stored on the floating ate.  When using these cells in a memory array, information may be written into or erased from each of the cells individually or a blanket erase may be employed for the entire or a selected section of the array.  To write and to erase a cell, a low single polarity voltage is employed.  Several embodiments of the invention are disclosed including one embodiment wherein the dual gates are located on one side of the floating gate, a second embodiment which uses a diffusion in a semiconductor substrate as one of the control gates and a third embodiment wherein one of the control gates is disposed on one side of, or above, the floating gate and the other control gate is disposed on the other side of, or below, the floating gate near the surface of the channel region of the transistor.

Abstract: SELF-ALIGNED METAL PROCESS FOR INTEGRATED CIRCUIT METALLIZATION                      Abstract A self-aligned metal process is described which achieves self-aligned metal to silicon contacts and sub-micron contact-to-contact and metal-to-metal spacing.  The insulation between the contacts and the metal is a pattern of dielectric material having a thickness dimension in the order of a micron or less.  The metal and dielectric structure is substantially planar.  The method for forming integrated circuits with this structure involves providing a silicon body and then forming a first insulating layer on a major surface of the silicon body.  A layer of polycrystalline silicon is formed thereover.  Openings are made in the polycrystalline silicon layer by reactive ion etching which results in the structure having substantially horizontal surfaces and substantially vertical surfaces.  A second insulating layer is then formed on both the substantially horizontal surfaces and substantially vertical surfaces. Reactive ion etching of this second insulating layer substantially removes the horizontal layers and provides a narrow dimensioned dielectric pattern of regions on the major surface of the silicon body.  The remaining polycrystalline silicon layer is then removed by etching to leave the narrow dimensioned regions on the major surface of the silicon body.  A conductive layer is blanket deposited over the narrow dimensioned regions and areas in between.  A blanket layer of a plastic material over the conductive layer to planarize the surface is accomplished.  Reactive ion etching the plastic material and the conductive layer is continued until the tops of the narrow dimensioned regions are reached.  The plastic material is then removed leaving the structure of patterns of metal filling the regions between the pattern of dielectric material having a thickness dimension in the order of a micron or less.

Abstract: MOBILE DATA TERMINAL CHANNEL BUSY ARRANGEMENT                ABSTRACT OF THE DISCLOSURE         A channel busy arrangement for use in a radio-based data transmission system comprising a plurality of data terminals.  A carrier activity signal (CAS) generated by a receiver associated with a data terminal is used to trigger a CAS pulse of approximately 300 msec.  A demodulated audio signal from the receiver is coupled to a SYNC detector for detecting a data synchronizing (SYNC) signal generally transmitted before a data message and to an optional continuous tone coded squelch system (CTCSS) for generating a CTCSS signal.         The CAS pulse, SYNC signal and CTCSS signal are logic ORed to generate a channel busy signal used for inhibiting data transmission.  Thus, data transmission is inhibited  only during a 300 msec CAS pulse, when a SYNC signal is present, or during valid non-data transmissions (voice) even in the presence of an interfering signal.

Abstract: ABSTRACT OF THE DISCLOSURE         This application discloses servo control circuits particularly suited for electric discharge machining apparatus which provide the input to the servomechanism which actuates the tool feed during machining.  These circuits respond to a setting of desired gap emf and an input of actual gap emf to control tool movement so as to equalize these inputs.  They respond to abnormally low gap emf during the machining "on" pulse to retract the tool to allow the gap to clear of debris.  The gap emf during the "on" period of the pulse cycle is stored in a small capacitor coupled to a high impedance input to power cir-cuits of the servo control, which capacitor normally retains most of its charge during the "off" time of the cycle.  Logic circuits responding to the pulse generator and the gap emf discharge this capacitor when abnormally low gap emf occurs during cycle "on" time.  The transistor-ized circuit directly supplying the servo valve operating coil (or other transducer controlling electrode feed) embody means to provide for control by inexpensive low power elements of small size and low energy dissipation.
