A plant species identification apparatus for identifying plant species is disclosed. A reference data storage part stores reference spectral data which indicate a reflectance spectral feature classified by area segments including a sunlit portion and a shaded portion in addition to the plant species. A data input part acquires hyperspectral data to be a target. A determination part specifies the reflectance spectral feature of a pixel for each of pixels of the hyperspectral data from the reference data storage part and to determine the plant species of the pixels based on a classification of the reference spectral data.

Plant species identification apparatus and method

A liquid crystal display which has spacers reliably joined with a pair of substrates of the liquid crystal display by using spacers adapted to the purpose with respect to material, structure, method of joining with the substrates, etc. A pair of substrates can be reliably joined with spacers, and the strength of the liquid crystal display against an external pressure as well as display characteristics can be thereby improved. A manufacturing methods for such a liquid crystal display is also disclosed.

In a process for preparing an ink for a drop-on-demand type ink jet printer, sonic vibration is applied to the ink which is being prepared or has been prepared so that a gas entrained into the ink by incorporation of a dye therein can be removed. This ink can be stably injected through a recording head, even if the size of the head is made smaller to increase the atomizing frequency, or the recording speed.

A magnetic brush developer for electrophotography by the reversal development system where a uniform positive charge is imparted to a photoconductive insulator, the insulator is irradiated with a light image to form an electrostatic latent image and the latent image is developed and visualized by a positively charged toner. The developer comprises a carrier of granulated magnetite particles, the surfaces of which are coated with a thermosetting resin containing a fine fluoropolymer powder and a fine magnetite or carbon black powder dispersed therein. When this developer is used, adhesion of the toner to the sleeve is not only prevented at the initial stage of printing but also after continuous printing, and even if continuous printing does conducted, the charge quantity is not reduce, therefore print quality does not degrade.

Magnetic brush developer for electrophotography

A flash fixing process characterized by using a powdery developing toner comprising at least 80% by weight of a bisphenol A/epichlorohydrin type epoxy resin or a polyester resin as the binder resin, 1 to 10% by weight of a dye or pigment as the colorant and 1 to 10% by weight of a specific aminium compound.
