Abstract: The present invention relates to a non-rotating direct current electric generator capable of generating a direct current with high efficiency without rotating a field magnet or an armature. The non-rotating direct current electric generator according to the present invention is a direct current electric generator generating a direct current. and is characterized by comprising a drive unit and a generator unit. wherein the generator unit comprises: a rod-shaped core member: a field magnet having a first hollow part in the center part along with the winding of an electric line. and disposed on the outside of the core member through the first hollow part: and an armature having a second hollow part in the center part along with the winding of an electric line. and disposed on the outside of the core member through the first hollow part.

Abstract: A nonvolatile memory device including a memory cell array, a first voltage generator configured to generate a word line operating voltage for each word line of the memory cell array, a second voltage generator configured to generate a bit line operating voltage of the memory cell array, and a temperature unit configured to determine, from a temperature range table, a temperature range for a temperature code according to a real-time temperature of the memory cell array, and to adjust a power supply voltage of the first or second voltage generator based on a selection signal mapped to the determined temperature range.

Abstract: A non-rotating alternating current (AC) generating device for generating an AC current, includes: two or more generator units which are placed next to each other, wherein the generator unit includes a round bar-shaped core member, a field magnet in which an electric line is wound and a first hollow portion is formed in the central portion, the field magnet disposed on the outside of the core member through the first hollow, an armature in which an electric line is wound and a second hollow portion is formed in the central portion, the armature disposed on the outside of the core member through the second hollow portion, a pole piece which is provided between the field magnet and the armature, and insulating plates which are disposed between the field magnet and the pole piece and between the armature and the pole piece.
