  • Publication number: 20180317508
    Abstract: There is provided a plasma sterilization apparatus that permits plasma sterilization providing a uniform sterilization for even sterilization targets having various kinds of three-dimensional shape such as agricultural products, under mild conditions so as to prevent damage and quality deterioration of the targets. A plasma sterilization apparatus includes a voltage-applying unit that applies a voltage to a sterilization target having conductivity; a pair of electrodes that apply, in a discharged state, the voltage applied by said voltage-applying unit to the sterilization target via a dielectric; and a position changing unit that changes a relative position between the pair of electrodes and the sterilization target.

  • Patent number: 8233960
    Abstract: The present invention provides a method and device of quantitatively or qualitatively examining and diagnosing chronic fatigue syndrome (CFS) by: irradiating a sample derived from an examinee or other animal with light having a wavelength in a range of 400 nm to 2500 nm or a wavelength in part of the range; detecting reflected light, transmitted light, or transmitted and reflected light to obtain an absorption spectral data; and analyzing absorbance at all measurement wavelengths or at specific wavelengths in the absorption spectral data by using an analytical model prepared beforehand.

  • Publication number: 20110028808
    Abstract: An object of the present invention is to provide apparatuses for examining/diagnosing clinical disease of cancer, systemic lupus erythematosus (SLE), or antiphospholipid antibody syndrome. Blood, blood-derived component, urine, sweat, nail, skin, or hair is irradiated with light having a wavelength of 400 to 2,500 nm or a part of the range, of which the reflection light, the transmission light, or the transmission reflection light is then detected to give spectroscopic absorbance data, and afterward a previously prepared analysis model is used to analyze the absorbance over the whole wavelengths or at a specific wavelength for the measurement to allow the achievement of the object.

  • Publication number: 20080113337
    Abstract: The present invention provides a method and device of quantitatively or qualitatively examining and judging the presence of virus infection, such as HIV, or the presence of prion infection by: irradiating a sample derived from an examinee or other animal with light having a wavelength in a range of 400 nm to 2500 nm or a wavelength in part of the range; detecting reflected light, transmitted light, or transmitted and reflected light to obtain an absorption spectral data; and analyzing the absorbance at all measurement wavelengths or at specific wavelengths in the absorption spectral data by using an analytical model prepared beforehand. The analytical model can be prepared by carrying out spectral measurement, with a perturbation being provided, and carrying out a multivariate analysis that brings out perturbation effects.
