Abstract: The present invention relates to a colored photosensitive resin composition and to a light shielding spacer prepared therefrom. The colored photosensitive resin composition comprises an oxime ester fluorene-based compound as a photopolymerization initiator in a small amount, which is capable of forming a cured film that is excellent in terms of such properties as sensitivity, elastic recovery rate, resolution, chemical resistance, exudation resistance, voltage holding ratio, and the like. Accordingly, a light shielding spacer prepared therefrom can be advantageously used for a liquid crystal display, an organic EL display, and the like.

Abstract: The present invention relates to a colored photosensitive resin composition capable of forming a cured film that does not generate uneven wrinkles on its surface at the time of its formation, and a light shielding spacer produced therefrom and used for a liquid crystal display, an organic EL display, or the like.

Abstract: There is provided a method for saving fault wave data, in which when a fault wave generated in a system is saved, a size of wave data is calculated, and the saving of the wave data is performed according to the size of the wave data, so that it is possible to implement the use of spaces of a buffer and a memory and the simultaneous saving of wave data simultaneously or subsequently generated. Accordingly, it is possible to minimize a delay in the saving of the wave data. Also, it is possible to record all accurate wave data even when consecutive faults occur. Also, it is possible to efficiently use the space of the memory.

Abstract: Disclosed is a lithium manganese borate-based cathode active material. The cathode active material can be used to fabricate a lithium ion secondary battery that has advantages, such as high output capacity and cycle capacity, in comparison with lithium ion secondary batteries using conventional cathode active materials. Also disclosed are a lithium ion secondary battery including the cathode active material and a method for preparing the cathode active material.

Abstract: Disclosed is a cathode active material for a lithium ion secondary battery which includes a lithium manganese borate compound and a manganese oxide. The lithium manganese borate compound contains a larger amount of lithium than conventional lithium manganese borate compounds. Therefore, a larger amount of lithium is deintercalated in a battery including the cathode active material, and as a result, the specific capacity of the battery reaches 100-160 mAh/g, which is much higher than that of conventional lithium ion secondary batteries (<80 mAh/g). Also disclosed is a method for producing the cathode active material.
