摘要： A thermal line printer includes a semiconductor chip for control of A .times. N heaters arrayed in N groups past which thermally sensitive paper is stepped B times in printing a line of characters in an A .times. B dot matrix. A sequential access memory stores N multibit words, one word for each character to be printed on a given line with a commutator cyclically to read words from the memory A .times. B times for each line to be printed. A ROM has an A .times. B dot matrix code therein for each available character. A time sequencer and decoder connected to the ROM is synchronized with the commutator to produce a different one bit output from the ROM each time each given word is read from memory. A set of N enable circuits leads from the ROM to N groups of heaters. A set of A enable circuits leads from the sequencer to A groups of heaters where one heater in each A group is from one of the N groups. A decoder interfaces the sequencer to the A groups of heaters and to the motor sequentially to enable the heaters in one A group for each memory cycle and in order through the A columns and B rows of the matrix.

摘要： A method of assembling, positioning, and making connections to a thermal printhead is disclosed. A substrate is provided upon which heating elements or mesas are mounted. Leads from these heating elements are continued on the same side of the substrate as the one on which the elements are located. The leads are brought to terminal pads where connections may be made to the logic circuit which selectively energizes the heating elements to form numerals or characters on heat sensitive paper. A flat flexible cable with conductor ends exposed is held in place so that the exposed conductor ends make contact with the terminal pads of one or more of such substrates. The substrates and cable are clamped together by two metal plates. This entire assembly is mounted on a spring-loaded pivot arrangement so as to hold the heating elements against the heat sensitive paper on an advancing platen. Connections may be made between the cable conductors and the printing logic to allow the heating elements to be energized.

摘要： A memory system includes a multiple memory pointer in which a pointer selection signal selects one of a plurality of memory pointers to generate an address signal for application to the memory for controlling the location of memory operations. In the preferred embodiment the memory is arranged in an X by Y matrix having X times Y individually addressable memory locations. A first pointer circuit has a plurality of address pointers, one of which is selected for generation of an X coordinate address. A second pointer circuit includes a single address pointer for generation of the Y coordinate address. The second pointer circuit may be a multiple pointer in an alternative embodiment. By provision of a number of individually addressable memories responsive to the same memory pointer system, separate application of address signals from differing address pointers to differing memories permits multiple memory operations in a single instruction cycle.

摘要： An error correction system is particularly suitable for user programmable calculators which may be programmed to perform a series of functions on data entries by means of a series of program steps entered into the calculator from a storage media such as recorded magnetic cards or the like. Data is stored in one or more pairs of tracks on the recording media with the first track of each pair for storing binary zeros and a second track of each pair for storing binary ones. Each time a binary zero is present, an alternating transition negative to positive or positive to negative appears on the zero's track of the storage media and each time a one is present an alternating transition negative to positive or positive to negative appears on the one's track of the storage media. For reading the data stored on the storage media, means such as a data latch is provided for each track for storing the direction of the previous transition positive to negative or negative to positive for that track and means for comparing the direction of such previous transition with the direction of the present transition. Whenever it is determined that the state of a bit of data is missing on a pair of tracks, i.e., no transition stored on either track for a given bit, the transitions located prior to, and following said missing bit will indicate the track on which the data bit should have been stored and hence the state of the missing bit. In an embodiment in which at least two pairs of tracks are utilized, the ORed output from the first pair of tracks may be compared to the ORed output from the second pair of tracks such that whenever a bit appears for the first pair but not the second pair it is determined that a bit is missing for the second pair.
