Abstract: A gear pitch error correcting system for a numerical control apparatus used for a machine tool including at least one pair of gears provided in a transmission line through which the rotating force of a servomotor is transmitted to a driven member. Gear pitch error correction values for the respective gears, which each correspond to a predetermined gear angle and collectively cover one gear rotation, are stored in a nonvolatile memory.

The superimposed pitch error correction value and an interpolation pulse from an interpolating means (B) are added together by an adder (C), to obtain a pitch error-corrected output pulse, which is then supplied to an axis control circuit (18).

Abstract: A method for transferring working conditions parameters of computer numerical control discharge machining devices comprises the steps of inputting the machining, editing the programmable ladder, using the ladder to simulate hardware and establishing the I/O port for transferring the working conditions parameters. Transferring working conditions parameters is done by two kinds of signals, data signals and a strobe signal. The number of the output terminals for these two signals are determined by the number of the working conditions parameters and the variations thereof. The ladder is edited in the programmable logic controller of the computer numerical control system and the working conditions parameters are on-line transferred out from the I/O port by using the combination of the data signals and the strobe signal so as to be able to use the least number of output terminals to transfer the most number of parameters and to be fit for all kinds of power supply systems made by different manufacturers.

Abstract: An adaptive digital filter has a series of delay elements for imparting a unit delay of one sampling interval to successive input data samples in order to concurrently obtain a set of data samples of different sampling items. Each set of data samples are multiplied by respective coefficients, and the resulting multiplier outputs are added together into a filter output for comparison with a reference signal. The coefficients are renewed a preassigned number of times during each sampling interval, and the last renewed coefficients are used for each new set of data samples. For such coefficient renewal, a plurality of arithmetic circuits are connected in parallel for simultaneously performing the necessary computations for the renewal of all the coefficients.

Abstract: A method of and apparatus for constructing a control system and a control system created thereby which is based on a finite state machine with constant code (FSMcc). An input preprocessor module normalizes input signals as required by the FSMcc logical processing unit. An output postprocessor module changes the normalized finite state machine outputs to real signals required by the controlled process or apparatus. The input preprocessor allows for a different finite state machine required for an application to be executed by the same constant code contained in the FSMcc microcode storage. An application logic table for the FSMcc is constructed using a specific organization of data representing application logic conditions. This organization allows the entire application logic to be expressed in a table of a technically feasible size. The size of the FSMcc application logic table memory is greatly reduced.

Abstract: A sample data position error signal detection means is described. This invention is suited for use in a digital sector servo in a magnetic media disk drive environment. In particular, the invention relates to the detection and presentation in digital form of position error signals (PES) representative of magnitude and sign of recording head displacement from a track centerline. The circuits disclosed provide a digital representation of PES suitable for direct application to a digital signal processor which controls overall servo positioning operations. The invention detects the PES by an integration method and incorporates the innovation of requiring only two integrators to demodulate a PES having an arbitrarily large number of phases. The invention uses a phaselock oscillator having a hybrid digital/analog phase detector to generate the coherent carrier sequence for synchronous detection of PES. A further innovation of the invention is the use of a fully digital automatic gain control circuit (AGC).

Abstract: The feedback calculation for a dynamic matrix control (DMC) system has been modified so that it can accommodate a delay period between the time when the output variable is measured and when the measurement is available for feedback. This was accomplished by storing the projection vectors calculated by the DMC system and then comparing them to the output variable measurements as they become available. The algorithm was modified to handle planned production rate changes by adding another term to the equation used to calculate the projection vectors. This term involves multiplying the dynamic matrix for a given disturbance variable by a vector of future changes in that disturbance variable.
