Abstract:
An armature for a permanent magnet brushed motor includes a shaft, a number of silicon steel laminations circumferentially around the shaft, a commutator adjacent to an end of the shaft, and an enameled wire winding wound around the silicon steel laminations and the commutator. A plastic sleeve capable of withstanding high temperature is disposed between the commutator and the silicon steel laminations and adjacent to the commutator. A plastic member wraps around where the enameled wire winding winds the commutator, and fixedly attaching to the plastic sleeve. As such, the plastic member establishes a first point of attachment at where the enameled wire winding winds the commutator and a second point of attachment to the plastic sleeve. The problem of the enameled wire winding being loosed or broken due to the armature's high-speed rotation is prevented, thereby enhancing the motor's robustness and operational life.
Abstract:
A fitting structure is provided for supply of gas and connectable between an air supply tube in the form of a hose or a plastic pipe and an air outlet of an air compressor and includes a fitting and a thermal insulation tube. The fitting includes a first coupling opening connectable with the air outlet of the air compressor and a second coupling opening connectable with the air supply tube. The thermal insulation tube has a first end part fixed inside the second coupling opening of the fitting and a second end part extending outside the second coupling opening such that a portion of the thermal insulation tube that extends outside the second coupling opening is received in the interior of the air supply tube. High-temperature air from the air compressor is conducted through the thermal insulation tube into the air supply tube without being directly applied to the fitting.
Abstract:
A pressure indication device is provided to connect to an inflation mechanism of an inflation machine. The pressure indication device includes a hollow tubular body in which a push bock is received in a manner of being movable by a pressure conducted into the hollow tubular body and connected to a linearly movable plate and biased by an elastic element. The hollow tubular body has a tubular wall forming a pressure relief hole at a preset position corresponding to a maximum allowable pressure level. A scale bar having graduations is provided along a moving path of the plate. The elastic force of compression of the elastic element serves as a reaction force (restoration and returning force) for the linear movement of the plate. A pressure conducted into the hollow tubular body from the inflation machine drives the plate to move and thus indicates the pressure level.

A pressure indication device is provided to connect to an inflation mechanism of an inflation machine. The pressure indication device includes a linearly movable plate and an elastic element. A scale bar having graduations is provided along a moving path of the plate. The elastic force of compression of the elastic element serves as a reaction force (restoration and returning force) for the linear movement of the plate. Correspondingly, a pressure is induced in an air compartment of the inflation mechanism the so that the moving distance of the plate is indicative of the pressure level and thus precise measurement of pressure can be realized.
Abstract:
A PCB includes an outer layer and an inner layer. An electronic component is mounted on the outer layer. The outer layer further defines a first pad, a second pad, a third pad, a fourth pad, and a number of via holes. The electrical performances of the first pad and the second pad are the same to that of the inner layer. The first pad and the second pad are conducted to the electronic component. The third pad and the fourth pad are respectively conducted to the first pad and the second pad through the electronic component. The electrical performances of the third pad and the fourth pad are different from that of the inner layer. The via holes are respectively electrically connected to the third pad and the fourth pad.
Abstract:
A display apparatus and a drive circuit for adjusting a screen refresh rate of the display apparatus and a method thereof are disclosed. The display apparatus comprises an OLED diode display array and a drive circuit. The drive circuit comprises a detection unit, a clock generating unit, and a timing control unit. The detection unit determines whether a plurality of frames displayed by the OLED diode display array are configured as a dynamic frame. The detection unit generates a first control signal when the displayed frames are not configured as a dynamic frame, and the detection unit generates a second control signal when the displayed frames are configured as a dynamic frame. The clock generating unit generates a clock signal, the frequency of which is a first frequency in response to the first signal, or a second frequency in response to the second signal. The first frequency is greater than the second frequency. The timing control unit sets the screen refresh rate of the display apparatus in response to the frequency of the clock signal.
