摘要:
A word processor, including a keyboard through which characters can be inputted, a memory device for storing inputted character arrays and a display device capable of multi-color displays, is so programmed that corrections and additions are automatically displayed in a different color from the rest for the convenience of editing. Codes for indicating the color of display can be also stored in the memory device. When a completed document is finally stored in a document file, however, such color codes are deleted such that the document can be outputted in one color.

A secondary battery includes a cathode, an anode, and an electrolytic solution. The anode or the electrolytic solution, or both contain a metal salt including an unsaturated carbon bond.
摘要:
An anode or an electrolytic solution or both contain a metal salt including an unsaturated carbon bond. The electrolytic solution contains an unsaturated carbon bond cyclic ester carbonate represented by Formula (1) or a halogenated cyclic ester carbonate represented by Formula (2) or both, and contains a cyclic ester represented by Formula (3), where each of R1 and R2 is a group such as a hydrogen group, where each of R3 to R6 is a group such as a hydrogen group; and each of one or more of R3 to R6 is a group such as a halogen group, where X is an ether bond (—O—) or a methylene group (—CH2—); each of R7 to R10 is a group such as a hydrogen group; and each of R7 to R10 is a group such as an alkyl group when X is the ether bond.

A press-working method comprises: cutting out a member with a predetermined shape from a sheet material, the member having a longitudinal direction; bending the member with the predetermined shape to form a bottom portion and a wall portion extending at an angle from the bottom portion as seen in a direction along the longitudinal direction such that the bottom portion has an arched surface as seen in a side view, using at least one plunger and at least one die, wherein an edge of the wall portion is allowed to expand along the plunger and the die while changes in a thickness of the wall portion is controlled by the plunger and the die, and wherein the step of cutting out a member is performed such that the wall portion has an edge with a preset shape after the bending step.
