摘要： An additive manufacturing method is provided for building a manufacturing object by building of repeating formation of one of a sintered portion or a fused portion by selectively heating a thinly developed powder material within a working region on the basis of drawing data derived from three-dimensional data of the manufacturing object and further formation of a new thin layer on one of the sintered portion or the fused portion. The additive manufacturing apparatus includes one or more channels connecting the inside and the outside of the region, and introduces a fluid into a crack progressing into the un-fused powder material through the channel after completion of building to forcibly cool one of the sintered portion or the fused portion, and the un-fused powder material.

摘要： A frequency converter receives a predetermined input signal and a predetermined local oscillation signal, and outputs a signal obtained by mixing the input signal with a harmonic signal having a frequency n times the frequency of the local oscillation signal, wherein a circuit that mixes the input signal with the harmonic signal is a harmonic mixer, which mixes the harmonic signal with the input signal using a nonlinear characteristic of a semiconductor element, and wherein the input signal or the output signal is subjected, either before input to the frequency converter or after output from the frequency converter, to correction on the basis of the amplitude and phase frequency characteristics of the frequency converter, which have been determined in advance.
