    摘要: A method of producing multilayered optical filters by using a genetic algorithm that determines an optimal combination of refractive indexes and thicknesses for each layer of the filter is described. The method generates initial values for the component and places the values within a matrix P, where P=(X1, X2, X3, . . . , Xi, . . . , Xs) and Xi is an elementary matrix that includes the refractive index and thickness of each layer i. The method may generate mutated patterns by increasing or decreasing the thicknesses and refractive indexes of the initial pattern. It may also perform a cross-over process, selecting patterns from grouping of mutated patterns. Alternately, the method may perform a process where selected patterns having optical characteristics closest to the desired characteristics from the initial, mutated or crossover patters are chosen. The genetic algorithm utilizing the above processes repeats until the optical characteristics fall within the desired range.

    摘要: Described herein is an optical multilayered-film filter which provides less interference and a good optical characteristic and is high in productivity. The optical multilayered-film filter wherein dielectric thin films are stacked on each other in a multilayer form in a single direction, comprises a refractive-index inclined laminated portion in which refractive indices of dielectric thin-film layers are successively inclined and changed in a laminating direction, and an alternately-laminated portion in which a dielectric thin-film layer having a high refractive index and a dielectric thin-film layer having a low refractive index are alternately laminated on each other.

In the production method, the crystal grain size of the sintered body is controlled to not more than 30 .mu.m, and abnormal grain growth and occurrence of pore can be restrained to easily produce a practically usable mixed oxide ceramic sintered body having excellent toughness inherent to oxide sintered body and excellent high-temperature strength inherent to SiC and Si.sub.3 N.sub.4 and uniform structure.

    摘要: An electric discharge machine designed to prevent an impactive high-speed motion generated upon actuation of an electrode actuator from propagating to a quill, as well as to enable the rapid retreat of a tool electrode by the electrode actuator to be performed efficiently. The tool electrode is attached to a quill through an elastic supporting element and a piezoelectric actuator, with the elastic supporting element disposed on the side of the quill. The elastic supporting element has an elasticity whose degree is set so as not to adversely affect normal positioning of the tool electrode, and the piezoelectric actuator facilitates rapid retreat of the tool electrode. A support body includes a counter weight having a weight large enough to absorb the component of the impactive high-speed motion of the electrode actuator which acts toward the quill.
