    摘要: A method of obtaining a very robust adaptive PI control method irrespective of fluctuation of parameters of a control object, wherein (speed command r-actual speed y) is used as a state variable Suf. Estimated values J*, A*, Gr*, and C* of inertia, coefficient of dynamic friction, gravitational disturbance depending on a robot angle, and Coulomb's friction, respectively, are obtained and a torque command .tau. is obtained in accordance with the following equation so as to cancel an error between each of the estimated values and its actual value to zero. .tau.=K2.multidot.Suf+(K1/s).multidot.Suf+J*.multidot.r'+A*.multidot.y+Gr*.multidot.sin .theta.+Cf*+.tau.1. The first and second terms of the right side of the above equation are identical with a torque command obtained by the PI control. Furthermore, r' represents an acceleration of command; .theta. represents a rotational angle of a robot arm; and .tau.1 represents a switching input corresponding to miscellaneous disturbance. As an error between each of the estimated values and its actual value becomes zero, a relationship of speed command r=actual speed y is obtained and therefore an adaptive PI control of a transfer function "1" is obtained.

    摘要: In order to simplify a hardware arrangement of a so-called Chien's searching circuit, an error location counter is provided. The error location counter counts up in response to each execution for detecting an error in a code word. If an error is detected in the code word, the content of the error location counter is latched by a suitable storage means and then applied to an external circuit.

    摘要: Using a Euclidean algorithm for error correction, an error correcting circuit corrects bit errors in a received codeword by making a difference detecting circuit (13) detect a degree difference between a higher and a lower degree polynomial. When the difference is equal to one, a dividing circuit (11) is supplied in a first stage of the algorithm with the higher and the lower degree polynomials as a dividend and a divisor polynomial. When the difference is greater than one, the difference is decremented by one to provide an amount of shift, responsive to which a shifting circuit (15) shifts coefficients of the lower degree polynomial to higher degree terms to provide a shifted polynomial. In the first stage, the shifted polynomial is used as the divisor polynomial. Preferably, an error number is calculated. From an error location polynomial, an error location number is detected. Only when the error location number coincides with the error number, the bit errors are correctable.

    摘要: An integrated optical and electric circuit device in which a semiconductor light emitting device is formed in a semiconductor integrated circuit substrate on which circuit units like logic circuits are integrated. The semiconductor light emitting device is activated by a common electric signal such as a clock signal to emit a common light signal. This common light signal transmits through the semiconductor substrate and reaches each circuit unit. A semiconductor light detecting device formed in the semiconductor integrated circuit substrate is coupled to each circuit unit. The semiconductor light detecting device is responsive to the common light signal to bring the corresponding circuit unit into a common signal receiving state. With this arrangement, a metal interconnection for the common signal which is to be simultaneously distributed to the circuit units becomes unnecessary.
