Title: Nonaqueous electrolyte secondary battery
Inventor: YOSHIMURA SEIJI
IPC: H01M10/0525
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To improve a storage characteristic and a cycle characteristic by including asymmetrical non-cyclic carbonate in a solvent and by using lithium trifluoromethanesulfonate or the like as a solute. SOLUTION: A non-cyclic carbonate used for the solvent of an electrolyte is low in viscosity, and is preferably one or more kinds within chemically stable methyl ethyl carbonate, methyl propyl carbonate, ethyl propyl carbonate, and methyl butyl carbonate. Since the ester is chemically stable in itself, the decomposition reaction of the electrolyte hardly occurs even if it is stored for a long time, so that this secondary battery having an excellent storage characteristic and cycle characteristic can be provided. One or more kinds within lithium trifluoromethanesulfonate, lithium hexafluorophosphate, lithium hexafluoroborate, lithium hexafluoroarsenate, lithium hexafluoroantimonate and lithium perchlorate are used for a solute.

IPC: G06F3/03
Filed: 2000-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a coordinate input tool capable of turning a switch on with small amount of pressure and lengthening a life of the switch. SOLUTION: When transcript is started, the pressure is applied to a pen point 63 and an ink cartridge 62 slides in the W direction indicated by an arrow. Then, a transom window 61b which is closed by a light shielding part 66b is opened and light L from the outside is detected by a phototransistor 67. When the phototransistor 67 turns power to a circuit substrate 70 on by detection of the light L from the outside, an alternate magnetic field is generated from a pen 60 and a coordinate position of the pen 60 is read. Thus, an energizing switch of the circuit substrate 70 is turned on with the small amount of pressure and the life of the switch is lengthened since no deterioration of a contact part is generated in comparison with the case of using mechanical contact switch.
