Granted: 1995-09-27
Abstract: FIELD: thermal-physical measurements. SUBSTANCE: quick-response thermal converter of the device is mounted onto unheated surface of the sample to transform temperature of the surface into electric signal. The signal has variable component of voltage with frequency of temperature wave received. Output voltage of the converter enters one input of differential low frequency amplifier. Low frequency signal enters the other input of the device from the generator, which signal is frequency-, amplitude- and phase transformed. As power of quick-response converter pulses with frequency, which is equal to doubled value of frequency of the generator, then frequency of signal, which enters the second input of differential amplifier is doubled by means of frequency doubler. In order to put amplitude of doubled frequency signal to the level of signal at output of the thermal converter, calibrated attenuation of signal of voltage divider is conducted for so many times, for how strong temperature wave is attenuated in the sample under control, when temperature wave is equal to thickness of the sample under control. Signal is delayed by electric delay unit for time, which is equal to total thermal time constant of quick-response heater and receiving quick-response thermal converter. EFFECT: improved precision of measurement. 1 dwg

Patent DE-19644550-C1 (DE)
Inventor: ZRENNER ARTUR DR
IPC: H01L41/09
Filed: 1996-10-26
Granted: 1998-06-10
Abstract: The object of the invention is to improve displacement and positioning inertia drives using linearly extending piezoelectric or electrostrictive actuators such that heavy objects which are clamped without play and with high static friction approaching the blocking force of the actuators can be moved by displacements in the cm range at a relatively fast displacement speed, highly uniformly and without hysteresis, and positioned in the nm range. To that end, the object is rigidly connected in the direction of extension or contraction of the actuator to the latter or to the clamping device in which a needle-like force-transmission element is secured on the actuator. The mass inertia of the object does not counteract the displacement when the length of the actuator changes in jerks as a result of being suitably stimulated electrically, such that the above advantages are attained. The possibility of displacing heavy objects in the cm range with high positioning accuracy opens up new areas of application for piezoelectric or electrostrictive displacement devices.
