ActiveUS20060284679A1Low powerLow noisePush-pull amplifiersPhase-splittersCapacitanceIntegrated circuit
An amplifying circuit includes an n-type transistor having a source, a gate coupled to a first bias voltage, and a drain coupled to a first supply voltage through a first impedance circuit. A p-type transistor of the circuit has a source coupled to the source of the n-type transistor, a gate coupled to a second bias voltage, and a drain coupled to a second supply voltage through a second impedance circuit. A first differential input is coupled to the gate of the n-type transistor through a first capacitor and to the gate of the p-type transistor through a second capacitor. A second differential input is coupled to the sources of the n-type and the p-type transistors. A third capacitor has a first end coupled to the drain of the n-type transistor, and a fourth capacitor has a first end coupled to the drain of the p-type transistor and a second end coupled to a second end of the third capacitor. An output of the amplifier circuit is provided at the second ends of the third and the fourth capacitors. The n-type transistor and the first impedance circuit serve as a common-source amplifier for a signal at the first differential input and as a common-gate amplifier for the signal at the second differential input. Similarly, the p-type transistor and the second impedance circuit serve as a common-source amplifier for the signal at the first differential input and as a common-gate amplifier for the signal at the second differential input.

Air-conditioner control system and control method thereof

The invention provides an air-conditioner control system and a control method thereof; the air-conditioner comprises a low output running mode with relatively low output energy and a high output running mode with relatively high output energy; the air conditioner can be mutually switched between two running modes, and the control system comprises a detecting unit, a judging unit, and a control unit. The detecting unit is used for detecting an inner ring of indoor environment temperature T; the judging unit is used for calculating the inner ring-T setting I of delta T=IT, and judging if delta T is not more than T1, wherein T is set as the indoor setting temperature of the air conditioner, T 1 is setting value and any positive number; the control unit can run the air condition in low output running mode or high output running mode according to the judging result of the judging unit. Through the invention, the room temperature can slowly change when closing to the T setting scale, prevent exceeding the setting temperature for too fast drop or rise of room temperature, avoid frequent startup of compressor, effectively prevent fluctuation of indoor environment temperature, and improve the comfort level of the indoor environment.

Novel three-axle swinging platform

ActiveCN104121929ALow powerLower frame heightMeasurement devicesDrive motorMoving parts
The invention discloses a novel three-axle swinging platform. The novel three-axle swinging platform can provide a three-freedom-degree swinging movement environment and mainly comprises a base, inner, middle and outer frames, inner, middle and outer axle systems, inner, middle and outer frame swinging rods, inner, middle and outer ball screws, inner, middle and outer stepping motors, inner, middle and outer frame connecting hinges and inner, middle and outer frame inserting pins. When movement-instruction pulse signals transmitted from an industrial control machine is received by the motors, the motors rotate forwards and reversely, the forward-reverse rotary movement of the motors is transformed into reciprocating linear movement by the ball screws, and the frames are pushed by the swinging rods, so that the swinging movement of the three frames of a rotary platform is realized. The novel three-axle swinging platform disclosed by the invention has the advantages that a transmission system is arranged outside the frames, the ball screws are used as moving parts of the transmission system, so that not only is the power of driving motors reduced by utilizing the transmission ratio, and the volume of a platform body is greatly reduced, but also the problems of transmission gaps, noise and efficiency loss and the like of the reciprocating movement are solved.
