Abstract: A cloud computing system includes a remote host, a portable computer comprising a display, a keyboard, a multiplex IC interface, a register interface, a network card interface and a display interface and linked to the remote hole through the internet when started up. When an array of signals are inputted into the portable computer by means of the keyboard, the inputted data is transmitted by the multiplex IC interface to the register interface and then transmitted through the network card interface to the remote host via the internet, and the data that is transmitted by the portable computer to the remote host through the internet is then computed by the remote host, and then the remote host transmits the processed data through the internet back to the portable computer, enabling the processed text and/or graphic data to be displayed on the display by the display interface.

Abstract: A weaving machine is constructed to use a magnetic traction device to reciprocate the shuttle in moving weft threads over warp threads at a high speed without producing noise and preventing direct contact between parts.

Abstract: A non-contact type wheel transmission structure is disclosed to include two transmission wheels set in proximity to each other without contact, each transmission wheel having grooves equiangularly spaced around the periphery and magnets respectively fixedly mounted in the grooves, the magnets of one of transmission wheel being reversed in polarity to the magnets of the other transmission wheel for causing magnetic attraction between the transmission wheels.

Abstract: A cleaning device for avoiding dissipation of polluted air due to smoking, including a chair body, a gas-collecting funnel, a sucking device, a filtering box and a control circuit. A main power switch is disposed on the chair body. The gas-collecting funnel can be pulled downward and extensibly opened to restrain the polluted air due to smoking within the funnel. An ash tray is disposed on an arm rest of the chair body. A microswitch is installed at the bottom of the ash tray for controlling the operation of the sucking device. The polluted air is sucked from the funnel through a gas conduit into the filtering box to be filtered and purified by a filtering cotton and active carbon. Therefore, the air can be cleaned and recycled and the dissipation of polluted air is avoided.
