Abstract: An apparatus for suppressing EMI in the differential high frequency data transmission is provided, including the use of a plurality of closed-loops next to the transmission wires of data plus and data minus used in the differential transmission of data transmission bus of the flash memory pen, the EMI generated in the data transmission can be suppressed. When data is transmitted through the bus as electrical current, the magnetic field will be changed and the flux is also changed, which will induce an electrical field in the closed-loops, which will, in turn, induce a magnetic field. Therefore, the magnetic field generated by the closed-loops will annihilate the magnetic field generated by the data transmission; and hence the EMI is suppressed. Further more, the closed-loop of the present invention cab be designed as different shapes, such as circles, rectangular or others. In addition, the number of closed-loops can also vary.

Abstract: A rubbish container with automatic compressing mechanism mainly including a housing, a plurality of rubbish bins positioned inside the housing to collect sorted rubbish, movement control channels provided in the housing to support a transversely extended top board, and an automatic compressing mechanism mounted on the top board. A motor is connected to one end of one of the movement control channels to rotate a threaded rod therein, so that the top board connected to the threaded rod and the compressing mechanism on the top board are brought to translate along the movement control channels to and fro in the housing over the rubbish bins. The compressing mechanism has a motor to drive a compressing member and a compressing plate connected to a lower end of the compressing member to move up and down, compressing rubbish collected in the rubbish bins to a reduced volume.
