A health-care nano-class board with the functions of killing bacteria, releasing negative ions, removing odor and emitting infrared ray is composed of a shaving board as substrate, a composite nano-class decorative film, and a thermosetting adhesive layer between first two layers.

The invention relates to a broadband radial pattern leaky coaxial cable used for subway and a manufacturing method thereof, and the leaky coaxial cable has the double functions of transmission line of information and duplexer. The structure of the leaky coaxial cable consists of an inner conductor, an insulation layer, an outer conductor and a jacket, wherein, the inner conductor is externally covered with the insulation layer which is externally covered with the outer conductor that is externally sheathed with the jacket, and the insulation layer that covers on the surface of the inner conductor adopts nitrogen or carbon dioxide physical foam to form a foamed polyethylene insulation layer; cambered slotted holes are opened on a clutch gold belt of the outer conductor covered outside the insulation layer. The manufacturing method comprises the steps: (1) a spiral wrinkle inner conductor is manufactured by longitudinal covering welding and embossing by using a copper strip; (2) the nitrogen or the carbon dioxide are adopted to be injected into the smelted polyvinyl plastics, and then the physical foamed polyethylene insulation layer is formed on the surface of the inner conductor by extrusion and cladding; (3) the slotted holes broken out by the clutch gold belt of the outer conductor are the cambered slotted holes; (4) the clutch gold belt of the outer conductor is covered on the insulation layer longitudinally, and the surface of the clutch gold belt of the outer conductor is crowded and covered with the jacket.

The invention discloses a small-range electromagnetic eccentric magnetic gear pair with a radial magnetic field, and can be widely applied to the field of transmission of industries such as wind power generation, electric vehicles and ship driving. The magnetic gear pair is characterized by consisting of a stator and a planetary rotor, wherein the stator consists of a stator enclosure 4, a stator core 5 with Z1 coil inserting slots and 2p1 stator windings 6 arranged in the slots; the planetary stator consists of a planetary rotor core 16 and 2p2 rotor permanent magnets 17 distributed on the outer circle of the planetary rotor core 16; pole pair numbers p1 and p2 have a small number difference, and are co-prime; the small-range stator is connected with the planetary rotor through an eccentric input shaft 1 on which a bearing IV15 is sleeved to form an eccentric structure; planetary rotor is driven by the eccentric input shaft 1 to revolve about a rotating shaft; a permanent magnetic field of the planetary rotor is coupled with an electromagnetic field of the stator through a radially eccentric air gap; the rotor permanent magnets 17 drive the planetary rotor under the action of the electromagnetic field of the stator to backwards rotate about own axis; and low-speed rotation is output through an output mechanism 9 and an output shaft 11.
