  • Patent number: 9995315
    Abstract: A ceiling fan motor housing and cover side fixing structure includes a motor housing, a cover and a stator. The motor housing includes a rotor and plural side guide holes formed on a sidewall. The cover includes plural fixing holes formed at an edge of a top circular flange, and the side guide holes opposite to the fixing holes are fixed by plural passing-through fixing members, so that the motor housing and the cover are combined for accommodating the stator to simplify the overall assembly of the ceiling fan motor effectively, and provide a convenient way of combining the motor housing and the cover without increasing the width. Further, the wire winding space of the stator in the motor housing and the cover of the ceiling fan motor is increased for convenient assembling.

  • Publication number: 20160038881
    Abstract: A tube assembly for a reverse osmosis filter cartridge has a tube body, an inlet port, an outlet port, two side assemblies and a stop cone. Each of the side assemblies has a block ring, a bearing plate, a sealing plate and a connecting tube. The sealing plate has a clamping segment and at least one rotation-stopping segment formed on an inward surface of the sealing plate, and the stop cone is securely mounted around the clamping segment and engages with the at least one rotation-stopping segment, thereby securely assembling the stop cone and the sealing plate to avoid relative shake and rotation.

  • Publication number: 20150176737
    Abstract: A block ring for a tube assembly for a reverse osmosis filter cartridge has multiple block segments connected to each other into a loop; any two adjacent ones of the block segments pivotally connected to each other, and outer ends of two of the block segments detachably abutting each other. For assembling, the block ring that is not formed into a loop yet is mounted into an outer annular groove of a tube body, and then the two block segments are rotated to make the outer ends abut each other. Thus, the block segments are braced transversely to securely abut the outer annular groove. Therefore, the block ring is securely mounted in the tube body. Besides, the block ring is integrated axially, such that the block ring can effectively and axially bear the outward abutting of a bearing plate, which prevents the block ring from deformation and enhances the safety.

  • Patent number: 7687446
    Abstract: A method of removing the residue left after a plasma process is described. First, a substrate having at least a material layer thereon is provided. The material layer includes a metal. Then, a fluorine-containing plasma process is performed so that a residue containing the aforesaid metallic material is formed on the surface of the material layer. After that, a wet cleaning operation is performed using a cleaning agent to remove the residue. The cleaning agent is a solution containing water, a diluted hydrofluoric acid and an acid solution.

  • Publication number: 20100030417
    Abstract: An environmental survey robot suitable for wireless communicating with a survey action management center having a geographic information system to scheme an advance route with multiple check points is provided. The environmental survey robot includes a moving vehicle, a controlling computer, a wireless communication network, a Global positioning system, an environment detector, a solar cell and a power controller. The wireless communication network receives the advance route from the detecting action management center, and the controlling computer autonomously controls the moving vehicle to move in accordance with the advance route. The environmental detector is suitable for detecting the environment information and sending the same to the controlling computer. When the electricity of the solar cell is less than a predetermined value, the power controller will send the signal to the controlling computer such that the action controller will stop the action of the moving vehicle.
