According to the vessel fast cable separating device, a user connects one end of the cable to the surface of the ground pile in a sleeving manner, then opens the box body of the fixed box and starts an air cylinder to descend, so that the problem that the cables of most existing vessels are separated manually to consume time and labor is solved, the labor force for manual cable separation is saved, the manual cable separation time is also shortened, and the cable separation efficiency of the vessel is also improved.

The present invention relates to a freeze-circulation process of air conditioner and control method for reducing its noise produced by short pipe placed in indoor side when the power supply is switched off. Said freeze-circulation and control method can obtain the following effects: between outdoor machine and indoor machine a change-over device is set, when the compressor is stopped, the medium flow path of the above-mentioned outdoor machine and indoor machine is changed by change-over device, so that it can prevent the medium from further flowing into indoor side, the medium is not passed through the interior of short pipe placed in indoor side so as to can prevent the short pipe interior from producing noise. Besides, when the compressor is stopped, the medium flow path is changed, said indoor machine and outdoor machine have respective independent medium circulation flow path.

The invention discloses a radiator dust clearing device for a notebook computer.

According to the radiator dust clearing device for the notebook computer, the structure is simple, design is reasonable, operation is convenient, the dust clearing problem of the radiator is well solved, clearing is fast, and the effect is also very good.

The invention discloses a large-current combined high-temperature inductor and a processing method thereof. The whole inductor is formed by bonding and combining an inductance magnet and an inductanceconductor. The inductance magnet comprises an external inductance magnet and at least one internal inductance magnet; the external inductance magnet is integrally formed, at least one conductor containing groove used for containing the inductance conductors is formed in the external inductance magnet in a penetrating mode, one inductance conductor is arranged in each conductor containing groove,and the remaining space in each inductance conductor and the remaining space in the corresponding conductor containing groove are filled with one internal inductance magnet. Effective integration of the inductor is achieved, the overall shape of the inductor is regular, pins on the inductor are all arranged on the outer surface of the same side of an inductor finished product, the shielding performance of the inductor is guaranteed, the overall size and occupied space of the inductor are reduced, and convenience is provided for subsequent installation and use of the inductor.

The invention discloses a noise-proof motorbike exhaust pipe with a large discharge capacity function. The pipe comprises an air inlet pipe body. One end of the air inlet pipe body is fixedly connected with an air outlet pipe body, and an inner cavity of the air inlet pipe body communicates with an inner cavity of the air outlet pipe body. An exhausting assisting device is arranged in the inner cavity of the air inlet pipe body. The inner wall of the air outlet pipe body is fixedly connected with the surface of a gas gathering pipe body. One end of the gas gathering pipe body is fixedly connected with the surface of a gas dispersing pipe body. Gas dispersing holes are formed in the surface of the gas dispersing pipe body. According to the noise-proof motorbike exhaust pipe with the large discharge capacity function, waste gas in the air inlet pipe body can blow fan blades on the exhausting assisting device when being exhausted, the fan blades are rotated, suction force is produced, thedischarge capacity of the exhaust pipe is increased, and accordingly, the phenomenon that waste gas in the exhaust pipe of a motorbike fails to be exhausted in time is avoided; by arranging the gas gathering pipe body and the gas dispersing pipe body, all the waste gas enters the gas dispersing pipe body, and then the waste gas is exhausted out of the gas dispersing pipe body; and since the gas dispersing holes are formed in the surface of the gas dispersing pipe body, when the waste gas in the exhaust pipe is to burst out, the waste gas is exhausted into the air outlet pipe body through thegas dispersing holes, pressure produced by the waste gas in the gas dispersing pipe body is reduced, and the phenomenon that noise is produced when the waste gas bursts out of the gas dispersing pipebody is avoided.
