  • Publication number: 20190191090
    Abstract: An object of the present disclosure is to continue optical image stabilization even in the case where a correcting lens is positioned near a mechanical end. An optical image stabilization module used to control a camera module adjusts the position of a correcting lens and the like used for optical image stabilization while executing the optical image stabilization during an exposure period. An image distortion accompanying the position adjustment of the correcting lens can be corrected by, for example, an electronic image stabilization module.

  • Patent number: 5629110
    Abstract: A method for producing a cathode active material for a non-aqueous electrolyte secondary battery, which comprises the step of heating a mixture of .beta.-Ni(OH).sub.2 and a lithium salt in the presence of oxygen at a temperature ranging from 600.degree. C. to 800.degree. C. to obtain LiNiO.sub.2.

  • Patent number: 5525443
    Abstract: A non-aqueous secondary electrochemical battery which comprises a complex oxide containing lithium for a cathode, a carbon material for an anode, and a mixed solvent for an electrolyte is disclosed. The mixed solvent is obtained by dissolving an inorganic salt in a mixture of a cyclic ester and a chain ester. The cyclic ester is selected from the group consisting of ethylene carbonate, propylene carbonate, butylene carbonate, and .gamma.-butyrolactone. The chain ester is selected from the group consisting of diethyl carbonate, dimethyl carbonate, ethyl formate, methyl formate, ethyl acetate, methyl acetate, and dimethyl sulfoxide. In this way, a non-aqueous secondary electrochemical battery having improved cycle life capabilities, discharge performance, and low temperature performance can be obtained.

  • Patent number: 5521027
    Abstract: A non-aqueous secondary electrochemical battery which includes a complex oxide containing lithium for a cathode, carbon for an anode, and a mixed solvent for an electrolyte is disclosed. The mixed solvent is obtained by dissolving an inorganic salt in a mixture of a cyclic ester and an asymmetric chain carbonate. The cyclic ester is selected from the group consisting of ethylene carbonate, propylene carbonate, butylene carbonate and .gamma.-butyrolactone. The asymmetric chain carbonate is selected from the group consisting of ethylmethyl carbonate, methylpropyl carbonate and ethylpropyl carbonate. In this way, a non-aqueous secondary electrochemical battery having an improved cycle life capability, discharge performance, and low temperature performance can be obtained.
