oscillator". Detection circuit The detection is done to detect the received ultrasonic signal. This is the half-wave rectification circuit with Shottky barrier diodes. The DC voltage according to the level of the detection signal is output to the capacitor behind the diode. The Shottky barrier diodes are used because the high frequency characteristic is good. As for the Shottky barrier diode‚ refer to "Diodes". Signal detector This circuit is the circuit which detects the ultrasonic which returned

PROJECT IN T.L.E Electronic Components Diodes a diode is a two-terminal electronic component with asymmetric conductance‚ it has low (ideally zero) resistance to current flow in one direction‚ and high (ideally infinite) resistance in the other. A semiconductor diode‚ the most common type today‚ is a crystalline piece of semiconductor material with a p–n junction connected to two electrical terminals. A vacuum tube diode has two electrodes‚ a plate (anode)

1.INTRODUCTION Most high-precision machines are positioning stages with Multiple degrees of freedom(DOF)‚ which often consist of cascaded long-and short-stroke linear actuators that are supported by mechanical or air bearings. Usually‚ the long stroke actuator has micrometer accuracy‚ while the Submicron accuracy is achieved by the short-stroke actuator. To build a high-precision machine‚ as much disturbances as possible should be eliminated. Common sources of disturbances are vibrations

transient analysis. The inductors in the circuit are replaced by their equivalent current sources and resistances‚ and the capacitors in the circuit are replaced by their equivalent voltages sources and resistances. The circuit voltages and currents are calculated at the time of switching (usually at t = 0); this is the initial condition solution. The voltages across the capacitors and the currents across the Inductors are used to calculate the circuit voltages and currents at each time step; this is

The ceramics used were Al2O3‚ AlN‚ PZT‚ SiO2 glass‚ and BeO. In order to determine the dielectric constant‚ a GenRad 1689 Digibride RLC apparatus was used to measure the capacitance. When a dielectric material is placed between the plates of a capacitor‚ an increase of charge storage capacity is expected. This is due to the polarization within the dielectric material itself‚ aiding in storing the charge at the plates. The methodology of the experiment was simple and straightforward. First off‚ the
