摘要： A novel multi-mode vibration damper is invented by using a pair of piezoelectric patches connected with negative capacitance shunt circuit units. A piezoelectric material connected with a series resistor-negative capacitor branch circuit is capable of suppressing the vibration and/or noise amplitudes in the low frequency range. The other piezoelectric material connected with a parallel resistor-negative capacitor circuit is for suppressing the vibration and/or noise amplitudes in the high frequency range. By combining two negative capacitance shunt circuit units, a multi-mode vibration damper is capable of suppressing the whole structure modes simultaneously. In order to describe the characteristic behaviors of a multi-mode vibration damper, the stiffness ratio and loss factor with respect to the non-dimensional frequency are considered. The mechanism of a shunt damper is also described as considering a shunt voltage generated by the shunt impedance. The example results show that the multi-mode vibration damper reduces the vibration amplitudes of the vibrating system significantly across a broadband frequency range.

摘要： A gallium nitride (GaN) based optical device and a fabrication method thereof are provided. The GaN based optical device includes a substrate, a p-type GaN (p-GaN) layer formed on the substrate, and a p-type ohmic electrode formed on the p-GaN layer, wherein the p-type ohmic electrode is formed of a triple layer comprised of a nickel (Ni) layer, a gold (Au) layer and an indium tin oxide (ITO) layer sequentially formed. The thicknesses of the Ni layer and the Au layer forming the triple layer are smaller than the thickness of the ITO layer. When the p-type ohmic electrode in the GaN based optical device is formed of a triple layer comprised of Ni/Au/ITO, the Ni/Au layers reduce contact resistance and the ITO, which is a transparent, conductive oxide layer, increases transparency and increases luminescence efficiency.

The vacuum gauge for measuring the pressure in a vacuum chamber includes: a signal generator that drives an electric current; an ammeter connected to the signal generator for measuring the current; a bridge circuit consisting of junctions of thermocouple wires, which is connected to the ammeter, wherein one junction of the dissimilar metallic wires is made in the form of a Peltier tip inserted into the vacuum chamber; and a lock-in amplifier connected to the two symmetrical points of the bridge circuit for detecting a voltage signal due to the temperature oscillation at the Peltier tip and thus measuring the pressure in the vacuum chamber. The thermal conduction vacuum gauge using a Peltier tip has a simple structure, and is of micron size, and operates at high sensitivity over a wide range of pressure, thereby enabling the measurements of a pressure at higher resolution than existing thermal conduction gauges while facilitating local pressure measurements.
