摘要： This invention discloses a low-voltage circuit breaker with a capability of tripping quickly. Its main feature is that at least one of the side faces of the contact device provides an open flange which has an internal through hole, and the bottom of a rotating shaft disposed on the bottom part provides a stressed member. The stressed member receives the over-pressure airflow escaping from the open flange of the contact device to generate a force. The force is passed to the activating member by the rotating shaft and is magnified, then hits the latch quickly and makes a trip. An intermediate step is bypassed due to the force produced earlier, the force which is produced by the electromagnetism part in the heat energy and electromagnetic system, so that the low-voltage breaker can open quickly and reduces opening time greatly and improve the breaking capability.

摘要： A prestressed pavement has apparatus to prestress the slabs, has slab abutments to resist the prestress force, has short-life friction-reducing medium to prevent the slab early cracking, has restraints to prevent the slab buckling, and has accumulators to control the prestress. The pavement does not need longitudinal tensile material, and can be built by continuous and one-time concrete casting. The prestressing is simple, fast, and may be delayed or made by stages. The techniques can be used to convert existing non-prestressed concrete pavements to prestressed pavements.

摘要： An impedance-matched amplifier utilizing a feed-forward linearization technique involving multiple negative feedbacks and distortion compensation without active tail current sources reduces noise, distortion, power consumption and heat dissipation requirements and increases linearity, dynamic range, signal-to-noise-ratio, sensitivity and quality of service. Some differential amplifier embodiments of the invention consume less than 2 mA at 5 Volts or 10 mW power consumption per 1 mW in peak and sustained output IP3 performance above 40 dBm. In contrast, for an input signal frequency of 200 MHz, a 16 dB gain state-of-the-art differential amplifier consumes 100 mA at 5 Volts with a peak output IP3 of 36 dBm while an implementation of a 16 dB gain differential amplifier embodying the invention consumes 77.7 mA at 5 Volts with a peak output IP3 of 46 dBm and sustained at or above 40 dBm over a wide frequency range.
