  • Method and system for estimating convergence of changes in dimensions of molded article over time
    Patent number: 11879722
    Abstract: An objective of the present invention is to provide a method, or the like, for estimating the convergence of dimensional changes in a molded article over time, by utilizing the polarization intensity of terahertz waves. The present invention provides a method for estimating the convergence of changes in the dimensions of a molded article over time, the method comprising: irradiating a molded article with terahertz waves at multiple positions thereon, wherein the molded article is irradiated with the terahertz waves at each position thereon in multiple orientations about the optical axis; measuring polarization intensities of the terahertz waves transmitted through or reflected from the molded article; and determining whether the polarization intensities at the multiple positions are in a given relationship with each other.

  • Gas treatment device and internal combustion engine
    Patent number: 9359926
    Abstract: A gas treatment device includes an electric discharger, an electromagnetic wave oscillator, an antenna, and a fan. The electric discharger ionizes gas in a target space. The electromagnetic wave oscillator oscillates an electromagnetic wave to be radiated to the target space. The electromagnetic wave is radiated by the antenna toward a gas ionization region in which gas ionized by the electric discharger is provided. The electric discharger ionizes gas and the antenna radiates the electromagnetic wave thereto to generate plasma. The fan moves at least a part of the electric discharger, thereby changing a location of the gas ionization region, thereby moving the location of the plasma.
