  • Configurable logic element with independently clocked outputs and node observation circuitry
    Patent number: 5309045
    Abstract: A programmable logic unit circuit comprising a data memory circuit, a combinational logic circuit supplied with at least two input signals, two input select circuits for, based on the stored data in the data memory circuit, selecting the two input signals supplied to the combinational logic circuit from more than two input signals, a clock-synchronized circuit for supplying the output signal from the combinational logic circuit in synchronization with a clock signal, and a 3-state-output type output select circuit for selecting either the output signal of the combinational logic circuit or the output signal of the clock-synchronized circuit, depending on the stored data in the data memory circuit.

  • Position discrimination device for a thumb wheel switch
    Patent number: 4502050
    Abstract: A position discrimination device for a thumb wheel switch comprises a shift register and a ROM. The output data from the shift register and the data, determined by an inverted output from the shift register and by an output from a conductive terminal which corresponds to a state of the thumb wheel switch, are written into the ROM. The ROM supplies data to the shift register and generates a code signal corresponding to the state of the thumb wheel switch.
