Abstract: For suppressing a deterioration of display quality due to a luminance defect, a display device, a method of correcting a luminance defect and a luminance defect corrector are provided. The display device includes a first substrate (SUB1) having gate lines (GL), data lines (DL), pixel electrodes (PIT), and a common electrode (CIT) on a first glass substrate (GB1), and a second substrate (SUB2) having a plurality of optically transparent parts (CF) and a light shield part (BM) on a second glass substrate (GB2). The first or second glass substrate (GB1) or (GB2) contains a dimmer (10) including a plurality of dimming regions (20) that reduce the transmission of light. The dimmer (10) is formed to be superimposed on a trapped foreign matter (33) in plan view. This reduces the transmission of light from the luminance defect to suppress a deterioration of display quality.

Abstract: To provide an SmCo-based rare earth sintered magnet having a small diameter and a multipolar magnetized magnetic structure and having a high coercive force and a high magnetization rate. The outer shape of an SmCo-based rare earth sintered magnet having a coercive force HCJ (kOe) at a room temperature (° C.) of 7.5 (kOe)<HCJ?27 (kOe) is formed into any one of a cylindrical shape, a ring-like shape, a columnar shape, and a disk-like shape. Multi-pole magnetization is performed on the SmCo-based rare earth sintered magnet so as to satisfy (diameter D/the number of poles p) (mm)<(4/?)

Abstract: An electrophoretic display base includes a base; a partition which is disposed on one surface of the base and in which the opposite side of the one surface is open; an electrophoretic dispersion liquid which contains a dispersion medium and charged particles filled in a cell on the base which is defined by the partition; and a lid which is disposed to block an opening of the partition, and has a porosity capable of passing the electrophoretic dispersion liquid therethrough.

Abstract: A circuit disconnection element that can open or short-circuit between a power storage element and a step-up/step-down bidirectional chopper circuit is provided in a power storage system, thereby preventing a self-discharge state in a process of charging. Furthermore, at the time of occurrence of an abnormality, the power storage element is detached from other devices including the step-up/step-down bidirectional chopper circuit. Accordingly, an energy loss of the power storage element at the time of power regeneration can be reduced to improve the energy use efficiency. Further, breakage influences such that the power storage element causes breakage in other devices at the time of occurrence of the abnormality can be prevented, thereby enabling to obtain an AC motor drive device having mounted therein a highly safe power storage system.

Accordingly, an AC motor drive device having mounted therein a power storage system is obtained, in which the power storage system can perform charge and discharge to and from the power storage element, regardless of a bus voltage and can increase energy use efficiency.
