  • Patent number: 11686317
    Abstract: A long-distance speed control system for a brushless DC motor of a fan is provided. The long-distance speed control system includes a switch connected with a mains power supply, a switch circuit, a voltage detection module, a power cord, a processing unit, and a drive unit, which can control the multi-stage rotational speed of the motor. In the field of brushless DC motors for fans, there is no need to use analog-to-digital conversion chips between the mains power supply and the processor, having the advantages of low cost, environmental protection, and reduction of waste of earth resources. Besides, the switch, the switch circuit and the power cord can withstand the mains power supply, having the advantages of less signal attenuation and long-distance transmission.

  • Patent number: 11434864
    Abstract: Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration allows a fluid to flow through a channel that in an un-tilted apparatus would require the gravitational potential energy of the fluid to increase (i.e., to flow uphill), but, because of the tilt allows the fluid to flow through the channel in a downhill direction. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels.

  • Patent number: 8241589
    Abstract: A measurement fluidic channel (17) is formed at almost the center of a flow cell (1). In general, the measurement region of a measurement apparatus is set to focus on almost the center of a measurement chip. When the flow cell (1) is mounted in the measurement apparatus, the focus of the measurement region is positioned just above the measurement fluidic channel (17). The measurement apparatus can more reliably measure a sample solution flowing through the measurement fluidic channel (17). A suction pump (18) is formed in regions around the measurement fluidic channel (17). When the flow cell has the same planar shape as a conventional one, the amount of sample solution which can be supplied can be increased, compared to a conventional structure in which components are formed in line. The time during which a sample solution flows through the fluidic channel can be prolonged, the amount of sample solution can be increased, and the measurement time can also be prolonged.

  • Patent number: 7913508
    Abstract: A cooling device for interior and exterior surfaces of a mud pump liner, in which one end of the suction tube 3 is connected to the water tank 2, with the other end of the suction tube 3 connecting to the intake port of the spray pump 4, and an end of the discharge pipe 5 is connected to the outlet port of the spray pump, with another end thereof connecting to the interior cooling nozzle 1; and said another end of the discharge pipe 5 is also connected with a exterior cooling nozzle 6, the spray port of the interior cooling nozzle 1 is placed inside the liner 7, and the spray hole of the exterior cooling nozzle 6 is placed outside the liner 7. The present invention additionally performs spraying against the outer surface of the liner and cooling it so as to sufficiently cool the liner/piston. In this way, the working temperature of the liner/piston is decreased and the service life thereof is extended. Experiments show that the working temperature of the liner/piston is decreased by at least 16° C.

  • Patent number: 7883325
    Abstract: First and second structures are connected by helical fibers. The orientation between the first and second structures are changed, and by doing so, the positions of the helical fibers are correspondingly changed. The position of change of the helical fibers can be used for a pumping effect, or to change some other fluidic characteristics. One other fluidic characteristics, for example, may use the movement of the helical fibers as a valve.
