Abstract: A hollow fiber degassing module includes: a hollow fiber membrane bundle including a plurality of hollow fiber membranes bundled into a cylindrical shape; a housing that houses the hollow fiber membrane bundle, includes a liquid supply port and a liquid discharge port that are formed in communication with spaces between the plurality of hollow fiber membrane, and further includes a suction port formed in communication with inner spaces of the plurality of hollow fiber membranes; and an outer support having a plurality of openings formed therein and disposed between the hollow fiber membrane bundle and the housing.

Abstract: The present invention is directed to a motor mechanism provided with first and second motor units as well as a differential gear unit. The differential gear unit is provided with three rotating members which are engaged mutually and rotate in constant differential ratio rates. One of the rotating shafts is provided in one of the motors, and a second of these rotating shafts is provided in the second motor. A differential pinion gear rotation axle shaft corresponds to the third rotating shaft. The differential gear unit will cause a drive axle shaft to rotate. The rotating shaft of the first motor rotates at a differential speed with respect to the rotating shaft of the second motor which is due to the difference of revolution between the differential gear axle and the revolution of the rotating shafts of both first and second motors.

Abstract: A random access memory for simultaneously reading or writing information into or from two memory cells in a memory matrix. At least two address control lines and two input/output data lines are provided for each cell of the memory matrix. Each cell is accessed independently through an arbitrary address control line. The particular input/output data line corresponding to the correct address control line is energized, thereby simultaneously accessing two memory cells.
