  • Patent number: 11249069
    Abstract: A cancer analysis system includes, so as to perform an efficient image analysis in a cancer screening test using nematodes: a light source unit that irradiates a plate on which nematodes and a urine sample are plotted, from below; a photographing unit that takes an image of the plate irradiated by the light source unit; and an analyzer that analyzes the image taken by the photographing unit. The analyzer: couples a prescribed number of pixels in the image into a larger number of pixels thereof; and performs a chemotaxis assay of the nematodes based on a time variation of information on a luminous center of gravity of the image.

  • Patent number: 10241106
    Abstract: There is no small ion detecting apparatus that quickly and easily performs mass spectrometry under atmospheric pressure. Therefore, in order to solve the problem, an electrode arrangement and an electrode holding form for enabling water clusters in outside air to be detected with high sensitivity are provided. By using such solving means, it is possible to detect ions in a place having spatial constraints.

  • Patent number: 8560249
    Abstract: A method of quickly detecting a handmade explosive in a bottle with a low erroneous alarm frequency is provided. A sample gas generated from a bottle placed on a bottle placement space is sucked-in, and ions of the sample gas are generated by an ion source and subjected to mass analysis. The presence/absence of a mass spectrum derived from the handmade explosive is determined from an obtained mass spectrum, and the result thereof is displayed on a monitor, thereby quickly detecting the handmade explosive in the bottle or the handmade explosive adhering to the surface of the bottle at a low erroneous alarm frequency.
