Abstract: A filter cartridge cleaning apparatus includes a housing, a brush mechanism for cleaning a filter cartridge passing through the housing, a guiding mechanism for feeding the filter cartridge toward a filter cartridge outlet of the housing, a water supply mechanism for supplying water to the filter cartridge, and a transmission mechanism for driving the brush mechanism and the guiding mechanism. The housing has a drain for draining sewage resulting from the cleaning process. The filter cartridge cleaning apparatus may be used with a water recycling apparatus to eliminate waste of water.
Abstract: A positive load alignment mechanism comprises a platform device in which are disposed a plurality of driving devices, movable devices and movable bearing platforms. The driving device is connected to the movable device, and the movable bearing platform firmly supports a movable platform of the platform device. The driving devices are used to drive the movable devices to perform the back-and forth or left-and-right or rotating movement, and the movable bearing platforms firmly support the movable platform. By such arrangements, it can achieve the objectives of high pressure resistance, simplified structure, high security, high accuracy and all-direction displacement.
Abstract: This invention discloses a container assembly of pallet structure with portable parts, including one or more side board unit, one or more corner connectors, one or more supporting pallets, and one or more laying boards. The side board unit further includes a side board and a bottom board. The side board has stop-by-contact section extends from each of side of the side board to engage with the groove of a corner connector. The bottom of the side board engages with the pallet to form a unit, while allowing laying boards to be installed within.
Abstract: A method for making a wrench includes a step of making a mediate member, a movable jaw and an adjusting member, a step of applying heat treatment to the mediate member, the movable jaw and the adjusting member, a step of cleaning respective surfaces of the mediate member, the movable jaw and the adjusting member, and coating a anti-rusting layer on the mediate member, the movable jaw and the adjusting member, and a step of combination to put the mediate member in a mold and making a body by way of injection to integrally connect the mediate member to a head of the main body, the movable jaw and the adjusting member are installed to the body.
Abstract: A rotating light-emitting structure for a shower head comprises a housing provided for accommodation of a coverture and a light-emitting device. The coverture integrally encloses the light-emitting device. The coverture and the light-emitting device are coaxially pivoted in the housing. The liquid flows in the housing and sprays from the housing to impact the coverture, so as to make the coverture and the light-emitting device rotate coaxially. The light-emitting device rotates to generate electricity for illumination. By such arrangements, when the power is cut off, the rotating light-emitting structure for a shower can emit light for illumination without using batteries or other power sources.
Abstract: A backrest assembly includes a rigid frame having an annular body. A connecting plate is interconnected between left and right sides of the annular body above a bottom side of the annular body. A plurality of supporting plates are interconnected between the connecting plate and the bottom side of the annular body. The annular body further includes a ridge extending radially outward from an outer peripheral face thereof and spaced from a front end face of the annular body, forming a ledge between the front end face and the ridge. A flexible board includes a flange formed on a rear side thereof. The flange is mounted around the ledge and abuts against the ridge. The board further includes a plurality of vents extending from a front side thereof through a rear side thereof. Fasteners are extended through engaging holes in the ridge into fixing holes of the board.
Abstract: A method of designing a reluctance resolver, and the resolver comprises a stator and a rotor, and an exciting coil and two sets of outputting wires wind around the tooth portion of the stator. The designing method comprises the following steps: fixing relative position; calculating the turn ratio of the stator; winding the coil of the stator; and designing the resolver. And the resultant resolver can improve the precision of calculating the position of the motor rotor.
