摘要:
A non-aqueous electrolyte secondary battery includes a positive electrode containing a positive-electrode active material, a negative electrode containing a negative-electrode active material, and a non-aqueous electrolyte, and is characterized in that the non-aqueous electrolyte contains 1.0 wt % or less of a compound represented by formula (1) and 2.0 wt % or less of a cyclic sulfate ester represented by formula (2), based on the total weight of the non-aqueous electrolyte. By using the non-aqueous electrolyte including a specified amount of the compound represented by formula (1) and a specified amount of the cyclic sulfate ester, when the battery is used at a low temperature after being stored at a high temperature, the increase of the internal resistance is inhibited.

摘要:
A secondary battery includes an opening portion provided to a case. A first sealing body is provided to the opening portion, the first sealing body being displaced or deformed by a pressure difference between an inside and an outside of the case in such manners that the first sealing body is pressed by internal pressure to allow outflow of inside air from the opening portion when the internal pressure in the case is higher than external pressure and that the first sealing body is pressed by the external pressure to prevent entry of outside air from the opening portion when the internal pressure in the case is lower than the external pressure. Pressure in a space surrounded with the case and the first sealing body is set to be lower than pressure outside the space.

摘要:
A microwave plasma treatment apparatus comprises a plurality of auxiliary magnets arranged around the periphery of a plasma formation chamber. A plurality of auxiliary magnets are disposed along the circumference of the plasma formation chamber while a plurality of auxiliary magnets may also be arranged in the axial direction of the plasma formation chamber. Also, the magnetic poles of every auxiliary magnet are respectively reverse in polarity to the adjoining magnetic poles of an auxiliary magnet(s) disposed adjacent thereto either along the circumference of the plasma formation chamber or in the axial direction thereof. This enables the whole high-density plasma to be substantially uniform throughout the inside of the plasma formation chamber.
摘要:
An adaptive type compression method for a color image in which each sequence of picture elements obtained by combination of sum-difference transformation with DPCM is compressed by being multiplied by an adaptive zonal filter. The sum-difference transformation is used to simplify transformation of the image into a spatial frequency zone. The zone filter characteristic is adaptively selected according to a predetermined transmission bit rate (compression rate). Further, this zonal filter characteristic is set so as to correspond with luminance and color difference signals. According to this method, image information to be recorded can be arbitrarily selected and distortion of the image at compressing and reproducing can be eliminated.

An object is to provide an electrode assembly for an electric storage device, such as a nonaqueous electrolyte cell, and an electric storage device that are capable of preventing increase of a short-circuit current at the time of occurrence of a short-circuit within a cell and have high safety. In order to achieve the object, provided is an electrode assembly for an electric storage device including a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode, in which at least one of the positive electrode and the negative electrode includes a current collector, an active material layer formed on at least one face of the current collector, and an undercoat layer formed between the current collector and the active material layer and including an organic binder that evaporates and decomposes when heated to a predetermined temperature or more.
摘要:
A shaded picture signal processing system and method which produces recorded pictures of high quality with a small number of gradation levels with the resolution of the picture maintained nearly unchanged. False contours appearing as quantization distortion are removed by dispersing noise of equal magnitude to the false contours throughout the whole picture or a specified portion of the picture so that the false contours cannot be detected by the human eye.
