Abstract: A computer-implemented method includes: acquiring an evaluation function represented by a product of high-degree polynomials; generating a quadratic polynomial equivalent to the evaluation function by applying a degree reduction one or more times to each of the high-degree polynomials that represent the acquired evaluation function without expanding the evaluation function; and performing annealing calculation on the generated quadratic polynomial.

Abstract: A die coating apparatus for applying coating solution onto materials such as wires. The apparatus includes a radial bearing in a position adjacent and prior to a floating die with respect to the advancing direction of the material to be coated, so that the material to be coated after having passed through the coating solution is passed through the radial bearing before advancing into the floating die. Thus, the undesirable lateral vibration of the material to be coated at the floating die is prevented and a coating film of uniform thickness is obtained on the material to be coated.

Abstract: A coating apparatus of die coating type for applying coating solution onto materials such as wires to be coated which includes a floating die having a hole therethrough gradually narrowing in the direction of advance of the material to be coated for allowing the material after having passed through the coating solution to pass through the die, and a thrust bearing provided with lubricating means for reducing the friction in the radial direction and disposed at the outlet side of the floating die in a direction normal to the path of advance of the material to be coated for improved follow-up performance of the floating die with respect to the lateral movements of the advancing material to obtain a uniform coating film on the material to be coated.
