Abstract: The present invention relates to a charging method of a lithium ion secondary battery including, as a positive electrode active material, a lithium-containing composite oxide containing nickel and cobalt and having a layered crystal structure. The charging method includes a first step of charging the battery at a first current of 0.5 to 0.7 It until the charge voltage of the battery reaches a first upper limit voltage of 3.8 to 4.0 V; a second step of charging the battery, upon completion of the first step, at a second current smaller than the first current until the charge voltage of the battery reaches a second upper limit voltage greater than the first upper limit voltage; and a third step of charging the battery, upon completion of the second step, at the second upper limit voltage. This provides a charging method of a lithium ion secondary battery, the method capable of achieving both a shortened charging time and an improvement in charge/discharge cycle life characteristics.

Abstract: The liquid jetting apparatus includes a head member having a nozzle, a supporting member that that can support a medium, a scanning mechanism that can cause the head member to relatively move with respect to the medium, and a liquid jetting unit that can jet liquid from the nozzle. An area storing unit stores a relative area to which liquid can be jetted from the nozzle while the head member is caused to relatively move by the scanning mechanism. An out-of-jetting micro-vibrating-area setting unit can set out-of-jetting micro-vibrating areas before and after the relative area. A micro-vibrating unit causes liquid in the nozzle to minutely vibrate. An out-of-jetting micro-vibrating controlling unit causes the micro-vibrating unit to operate when the head member is located in the out-of-jetting micro-vibrating areas, while the head member is caused to relatively move by the scanning mechanism, based on the out-of-jetting micro-vibrating areas and head-position information.

The liquid ejecting device further includes a meandering correction pattern forming unit that forms a meandering correction pattern along the first direction in a margin outside the regulated landing area of the landing target and a meandering correction pattern detecting unit that detects the meandering correction pattern formed in the landing target by the meandering correction pattern forming unit.

Abstract: A printing apparatus includes a transporting unit that transports a printing medium in a transport direction. A print head group has print heads disposed at an interval in the transport direction. Each of the print heads has ink ejecting nozzles in a range substantially perpendicular to the transport direction, including a margin area outside an image forming area in the printing medium.

A print head corresponding to the detection unit prints a checking timing pattern when the reference timing pattern is detected, thereby controlling the ink ejection timing of the printing apparatus.
