Abstract: An electric garbage disposer of a construction comprising a container means having an opening defined therein and made of microwave shielding material; and a garbage receptacle having a receiving mouth defined therein and made of material having both of a microwave permeable property and a gas permeable property. The garbage receptacle is adapted to be removably accommodated within the container means with the mouth substantially aligned with the opening of the container means. A microwave generating means is used for radiating microwaves into the container means to heat garbage contained in the garbage receptacle within the container means. A water component produced by the garbage as a result of microwave heating is drained to an outside of the garbage disposer.

Abstract: An arrangement for transferring power of an engine to front and rear propellers of a ship comprises an inner propeller shaft directly coupled to the engine, an outer propeller shaft coupled to the engine via the planetary gear set in a manner such that the front propeller rotates in a direction opposite to the direction the rear propeller rotates. The planetary gear set includes first planetary gears coupled to the inner propeller shaft and secondary planetary gears coupled to the outer propeller shaaft and one clutch is provided between each pair of first and second planetary gears. Since there are provided a plurality of clutches, the torque imposed on each clutch is relatively small. Also, the torque on the clutch is reduced by the planetary gear set. Therefore, a clutch of small capacity can be employed. This makes the arrangement compact and the maintenance of the clutch easy.

Abstract: A television receiver is disclosed, which receives two television signals and compresses a time axis of one of the television signals and inserts the compressed signal to a portion of the other television signal to display both signals on the same screen. A signal indicating a boundary of the two images is produced from a synchronizing signal derived from one of the two received television signals and the boundary indicating signal is superimposed on one or both of a brightness signal and a chrominance signal to display the boundary.
