Abstract: An electric power generator device includes a dynamic force source device for generating a dynamic force, a generator further comprising a rotor with an axle for generating electric power with a low rotor speed. and a moment transmission mechanism at least having a first rotating component and a second rotating component; wherein the first rotating component links the second rotating component, is driven by the dynamic force source, and has a contact with the second rotating component being applied by the dynamic force; the second rotating component has a radius being longest in all the rotating components and a center joining the axle; the radius measured from the contact to the center is defined as a moment arm; the moment arm allows the second rotating component to impose a moment on the rotor with the axle so as to perform rotary motion of the rotor and electric power generation of the generator.

Abstract: An electric power generator device includes: a dynamic force source device for generating a dynamic force driving a rotor of a generator to perform a rotary motion via moment transmission mechanism; the generator for generating an electric power, the generator including the rotor; the moment transmission mechanism disposed between the dynamic force source device and the rotor of the generator and adapted to lengthen a moment arm between a point of application of the dynamic force and the rotor, such that the moment arm thus lengthened allows the dynamic force transmission mechanism to impose a moment amplifying effect on the rotor, thereby driving in a labor-saving manner the rotor to perform the rotary motion.

Abstract: A semiconductor memory device capable of compression and decompression is disclosed. With the semiconductor memory device having a built-in compression function, once external digital data need to be written to the semiconductor memory device, the semiconductor memory device can compress the external digital data and write the compressed external digital data to a semiconductor memory cell array, thereby enhancing data storage capacity. Furthermore, with the semiconductor memory device having a built-in decompression function, once electronic devices need to read data of the semiconductor memory device, the semiconductor memory device can decompress the data and output the decompressed data to the electronic devices.
