  • Publication number: 20210356723
    Abstract: A zoom lens system includes: a first lens group having positive power; a second lens group having negative power; a third lens group having positive power; a fourth lens group having negative power; and a fifth lens group having positive power. The first lens group is made up of a single lens. The second lens group is made up of four lenses.

  • Publication number: 20210346954
    Abstract: This invention provides, by simple mechanical treatment, a metal powder that generates no smoke phenomenon when laminating and shaping a metal object even when decreasing a preheating temperature. In the metal powder, a solidification structure including a dendritic structure on the surface of the metal powder has been flattened. The solidification structure including the dendritic structure has been flattened by mechanical treatment including collision treatment of the metal powder. The mechanical treatment is performed by heating the metal powder to 100° C. to 300° C. The metal powder is a metal powder that is heated to a predetermined temperature and whose capacitance component of a measured impedance becomes zero. This metal powder is a powder of a metal alloy produced by an atomization process or a plasma rotation electrode process. The metal alloy includes a nickel-based alloy, a cobalt-chrome alloy, an iron-based alloy, an aluminum alloy, and a titanium alloy.

  • Publication number: 20200412458
    Abstract: A front-end circuit is used to test an RF signal from an RF device. The RF signal is generated by modulating a carrier signal having a carrier frequency with a wideband baseband signal. A variable frequency oscillator generates a local signal having a variable local frequency. The first frequency mixer frequency mixes a local signal and an RF signal to generate an IF signal having a frequency. A band-pass type first filter filters the IF signal. The local frequency can be selected from a plurality of frequencies having a frequency interval equal to or narrower than a bandwidth of the first filter.
