Abstract: Disclosed is a bicycle which is a means of short-distance movement favored by men and women of all ages. The present invention is an application of a bicycle having a motor-generator disclosed in Korean Patent Application No. 2009-035298 that the applicant of the present invention filed. Namely, a motor-generator is mounted on a side of the rear wheel of the bicycle, and a control box and a battery are mounted under the main pipe of the bicycle, and a change-over switch and a change speed switch are mounted on the handle of the bicycle. The present invention makes it possible to charge quickly and effectively via a motor-generator that is operated by the bicycle driving force on a downhill or level ground, and with charging made, the rotary force of the motor-generator is conveyed to the rear wheel to generate electric power, so that electromotive force is produced and stored by itself, and the driving force of the bicycle can be obtained by using the stored electric power.

Abstract: Disclosed is a generator that can produce electric power using water power, wave power or wind power. The generator characterized in that a plurality of magnet plates and separately-arranged coil plates are constructed in such a way that they can rotate in mutually opposing directions, and these magnet plates and coil plates are continuously and sequentially arranged on a rotating shaft, and a plurality of induction coils and electromotive coils installed on inner and outer cylinders proximate to the opposed ends of magnets arranged on the magnet plates are separately arranged on the coil plates. According to the generator, it is possible to obtain a further increased quantity of generation by means of the magnet plates and coil plates that rotate in mutually opposing directions even in the case that water power or wind power used in generation is weak.

Abstract: A refrigerator is disclosed, in which shielding members installed on doors installed in a pair at both sides of the front surface of a main body shield a gap between the doors when the doors are closed. The gap between the doors is not exposed when viewed from in front of the refrigerator even when the assembly state of the doors is deformed or the doors are not completely symmetrical with each other, thereby effectively preventing the external appearance of the front part of the refrigerator from being spoiled due to the exposure of the gap between the doors.

Abstract: A refrigerator including a main body cabinet having an opening at a side; a door provided on the main body cabinet to open/close the opening; a hinge provided between the door and the main body cabinet to rotatably support the door with respect to the main body cabinet; and a door reinforcement disposed inside the door to be connected to the hinge and to prevent a twist of the door, the door reinforcement having a plate shape and formed with a hinge accommodating part to accommodate the hinge therein.

Abstract: A vertical partition cover assembly of a side-by-side type refrigerator includes a cover (70) coupled to the front of a vertical partition (20) and a fixing member (80) for fixing a hot tube (60) to the inside of the cover (70). The cover (70) includes a sealing surface (75) to closely contact gaskets and a mechanism (41) which holds the sealing surface to the front of the vertical partition. In one embodiment, the mechanism includes connecting portions (76,77) extending inward from both ends of the sealing surface (75), and a pair of pocket portions (71,72) formed at each end of the connecting portions (76,77) to hold the front ends (23,24) of liners (21,22) forming the vertical partition (20).
