Abstract: A lubricated bushing is mounted in a mounting cavity in a bushing housing and has a body and a flange. The body has an axial hole formed coaxially through the body to rotatably hold a shaft of a rotor of a fan and a bottom concentric recess formed in a bottom end of the body. The flange is formed on and protrudes radially out from the outer wall of the body, is mounted against an inner wall of the mounting recess, extends longitudinally from the top end of body and is shorter than half the body. Even though the inner wall of the mounting cavity tightly compresses the flange, the compressive force cannot be effectively transmitted to the body to deform the axial hole, so the shaft is kept from seizing up in the axial hole.

Abstract: A container that radiates far-infrared rays includes an airtight storage space for storing food, a far-infrared coating and multiple ceramic particles. The far-infrared coating is applied on an external wall of the container. The ceramic particles are spread in the far-infrared coating that radiates far-infrared rays. The far-infrared coating radiates far-infrared rays in a natural status with the ceramic particles. The storage space can be used to store solid food, soft drinks or the like, so as to prevent the food from bacteria propagation and also can keep fresh by the continuous radiation of the far-infrared rays. In this way, an expiry date of the food can be extended without adding excess preservatives. Moreover, the far-infrared rays radiated from the ceramic particles further can make water molecules active. Hence a tasting flavor of food is changed depending on different liquid food.

Abstract: A DC brushless fan motor driving circuit has a Hall PWM signal generator, a speed signal generator, a PWM driver and a full-bridge switching circuit. The Hall PWM signal generator obtains a Hall sine wave signal from an external Hall sensor and converts the Hall sine wave signal to a varied Hall PWM signal. The speed signal generator is connected to an external PWM input signal to set speed of a fan motor and a low speed voltage to determine a present speed setting signal. The speed signal generator further obtains the varied Hall PWM signal to compare the present speed setting signal to generate a SPWM signal to the PWM driver. The PWM driver outputs a SPWM signal to the full-bridge switching circuit and then coil current is formed close to a sine wave signal to decrease the electromagnetic noise.
