  • Patent number: 8603678
    Abstract: A positive electrode active material for a nonaqueous electrolyte battery. The positive electrode active material has been manufactured through a mixing step and a heating step. In the mixing step, a mixture is produced by mixing niobium pentoxide (Nb2O5) with lithium hydroxide (LiOH) at a molar ratio of 1:1. In the heating step, the mixture is heated in an atmosphere of air at substantially 800° C. The positive electrode active material having been produced through the mixing process and the heating process causes the plateau potential in a discharge to be approximately 1.0 [V] for lithium. And the nonaqueous electrolyte battery using the positive electrode active material can operate at a voltage of approximately 1.0 [V].

  • Patent number: 8105710
    Abstract: A battery 10A with leads has a low-profile external casing acting 11 as one of a pair of electrode terminals and a closure plate 12 acting as the other of the electrode terminals. The closure plate 12 hermetically seals an opening of the external casing 11 via an insulating gasket. A pair of lead plates 13 and 14 are each welded to a different one of the electrode terminals 11 and 12. One of the lead plates 13 and 14 is secured to a circuit board X. The lead plate 14 that is secured to the circuit board has a net-like structure.

  • Patent number: 7625666
    Abstract: A lead plate-attached coin-type battery is constituted from a combination of a coin-type battery and a positive lead plate. In the coin-type battery, a negative cap seals the aperture of a positive outer can. In a lateral view, the positive lead plate is crank-shaped, and one end thereof is attached to the outer surface of the positive outer can of the coin-type battery. A lead plate is not attached to the negative cap. One or more projections that project in the Z axis direction are provided on the negative cap. In the lead plate-attached coin-type battery, the positive lead plate and negative cap have been attached to respective conductive lands on a circuit board by a solder reflow method.

  • Publication number: 20090070295
    Abstract: Convenience of a user is improved in handling data included in a plurality of structured document files. A child document file is created by a schema inheriting a schema in a parent document file in which a plurality of tags are structured. A name of a substance tag in a child document file inheriting a model tag included in a parent document file is changeable in accordance with a user's input direction. At the time, a tag mapping table is held, in which a name of a substance tag included in a child document file and a name of a model tag which is the origin of the substance tag are associated with each other. A name of a substance tag corresponding to a model tag of which name is a search key is detected, with reference to the tag mapping table, and then, the data of the substance tag is detected from the child document file, by using the name of the substance tag as a new search key.
