  • Patent number: 7639850
    Abstract: An apparatus for and a method of analyzing components using microscopic regions. The apparatus includes: an image obtainer obtaining an image of a part of a living body; a color information generator generating color information of an image having a matrix pattern from a size of the microscopic regions and the obtained image; a first data transformer transforming the color information of the image into a product of first and second matrixes; and a component analyzer analyzing components of the obtained image using at least one of the first and second matrixes. When the obtained image is divided into a plurality of microscopic regions, the size of the microscopic regions is determined so that concentrations of components of the part fluctuate in each of the microscopic regions.

  • Patent number: 7588320
    Abstract: Disclosed are a droplet ejection device and method using an electrostatic field. The droplet ejection method includes: setting a separate electric field direction in each of a plurality of nozzles; supplying one of ink and ink containing particles to each nozzle; and forming and ejecting a plurality of separate ink droplets. The droplet ejection device includes a deposition part having electrode layers and insulating layers deposited toward a nozzle. Therefore, it is possible to readily perform droplet ejection without a heater or diaphragm vibration device. In addition, it is possible to reduce impact applied to the ink and obtain good print quality, since the ink is ejected using the electrostatic field.
