A positive electrode active material includes a lithium complex oxide particle, and a coating layer formed on at least a part of the surface of the lithium complex oxide particle. The lithium complex oxide particle is a lithium complex oxide particle composed mainly of nickel. The coating layer contains an oxo acid and/or an oxo acid compound, an acidity of the surface of the lithium complex oxide particle composed mainly of nickel is increased by the coating layer. The acidity is determined based on a pH of a supernatant of water in a state where after 1.0 part by weight of the lithium complex oxide particle composed mainly of nickel and having a coating layer formed thereon is dispersed in 50 parts by weight of water. The lithium complex oxide particle sediments, and the pH is less than 8.0.

An electronic watermark embedding apparatus and an electronic watermark embedding method can severally deal with both of the resistance property of an electronic watermark and the prevention of image quality deterioration. Electronic watermark information of a high importance level is embedded in a component having a strong resistance property, and electronic watermark information of a low importance level is embedded in a component exerting little influence on an image quality. As a result, the electronic watermark information to be embedded in the component having a strong resistance property is limited to that of a high importance level. Moreover, the image quality deterioration can be suppressed in comparison with the case of embedding all pieces of information, and the electronic watermark information of low importance level is embedded in the component having a weak resistance property but exerting little influence on an image quality.
摘要:
In a multipass printing that performs a plurality of printing scans over a unit area of a print medium by using a leading head and a follower head, the multivalued image data for the leading head is distributed according to the print volume information for up to the preceding printing scan. Then, the multivalued image data for the leading head is subjected to the grayscale level reduction operation to generate binary data. Based on the binary data, the print volume information is updated, after which the multivalued image data for the follower head is distributed according to the print volume information. This causes a plurality of printing scans or a plurality of print heads, that print the same unit area, to have a correlation among them, with the result that dots on a plurality of planes when overlapped have an excellent scattering characteristic.

A battery is provided which has a high capacity and can improve battery characteristics, such as cycle characteristics. The battery includes a spirally wound electrode body, wherein a cathode and an anode are wound with a separator in between. The anode includes, for example, simple substances, alloys, compounds of metal elements or metalloid elements capable of forming an alloy with Li, the like and combinations thereof. An electrolytic solution wherein an electrolyte salt is dissolved in a solvent is impregnated in the separator. For the electrolyte salt, a light metallic salt having B—O bond or P—O bond, such as difluoro[oxalato-O,O′]lithium borate and tetra fluoro[oxalato-O,O′]lithium phosphate, can be used. By forming a stable coating, decomposition reaction of the solvent can be inhibited, and reaction between the anode and the solvent can be prevented.
