• Dissipating Static Safely
  Though it is an old problem, the dissipation of static discharge is under intense scrutiny by plastics suppliers. They are now fielding materials better able to keep test equipment out of trouble. Semitron ESd 225, with a heat-deflection temperature of 225 F and a surface resistivity of 10 O/sq...
• Down-to-earth role for imidized polymers
  applications where even brief interruptions in power can cause problems. A wide range of semiconductor-device handling parts are machined from polyetherimide. This conductive PEI based material called Semitron ESd 410C has a heat-deflection temperature (at 264 psi) of 392 F. Designers of the B-2 Stealth Bomber...
• Precision moves with pint-sized motors
  . The majority of PZT devices used commercially are called low-voltage stacks. This moniker distinguishes them from PZT actuators that need in excess of 500-V drive signals. The lowvoltage versions have thin layers (about 0.1 mm) to permit deflection with electric fields of lower intensity. Use...
• Precision Actuator Puts New Spin on Solar Power
  a more-powerful and rugged hydraulic motioncontrol system that meets its objectives for low-cost power generation. "Power-plant efficiency depends heavily on how well the parabolic mirror array concentrates and maintains the sun's energy at the focal point of the tubes carrying the heat-transfer thermal fluid...
• Optimize HVAC and Process System Efficiency by Matching Your Plant and Processes To The Right Flow Measurement Technology
  rate with thermal sensors. flow measurement is required. is determined by measuring the temperature rise of a. fluid (heat gain) or the temperature drop of a heated. Positive Displacement (PD). PD measures the. sensor (heat loss). Thermal flow devices provide direct. volumetric flow rate...
• Made To Measure
  at a particular and instantaneous time in a shaft. Torque is usually measured in one of two ways, either by sensing the actual shaft deflection caused by the shaft twisting or by measuring the effects of this deflection. It is then possible to deduce the torque in the shaft. Classical torque sensors...

  and flame spread to the filling material. BTU. British Thermal Unit. The quantity of heat required to raise the temperature of one pound of water from 60o to 61o F at a constant pressure of one atmosphere. Block. See Bun. Blowing Agent. A gas, or substance capable of producing a gas, used in making...
• MICRO: Product Tech News
  for further epitaxial deposition. The wafer addresses the heat problem that affects high-power and high-speed transistor products: excessive heat buildup and ultimate device failure. Because of the subnanometer proximity of the chip's active region to the diamond, the GaN-on-diamond wafer removes...
