Dual precision operational amplifier with zero adjustment
2001 Siberian Russian Student Workshop on Electron Devices and Materials. Proceedings 2nd Annual (IEEE Cat. No.01EX469), 2002Precision operational amplifiers are used to gain low electrical signals accompanied by high level of noise. They have low offset voltage with thermal drift, high common-mode rejection ratio, high input resistance and low noise. The dual precision operational amplifier designed in this article can be used to construct devices of high accuracy with ...

An operator assistance system for beam adjustment of a cyclotron
IEEE Transactions on Nuclear Science, 1992The authors discuss a computer-based operator system for cyclotron operators. The main feature of the system is a visual display of feasible setting regions (FSRs) of adjustable parameters. The FSR, derived from constraints among these parameters, shows the valid ranges where set points can be adjusted. Search traces by the operator are superimposed on

Use of the Operating Microscope: Adjustment and Compensation for Refractive Errors
Archives of Otolaryngology - Head and Neck Surgery, 1969USE of the operating microscope has now become a sine qua non for good otologic surgery. Effective use of the microscope demands comfort and in a prolonged operation this requires not only practice, but optimal adjustment of the instrument. If your eyes seem to strain to focus after using the microscope for a few minutes or you are having to refocus ...

Cardiopulmonary Adjustments During Operant Heart Rate Control
Psychophysiology, 1990ABSTRACTTwenty‐three healthy men and women participated in a 5‐session experiment in which they attempted to increase and decrease their heart rate with the assistance of visual analogue biofeedback. As a group subjects did successfully raise and lower heart rate from resting baseline. These changes in heart rate were closely paralleled by changes in V̂

Self-adjusting clutch with low operating load
ATZ worldwide, 2003Increasing torques of passenger car engines require measures to reduce the operating loads. The introduction of the selfadjusting clutch SAC by Luk was a first step, the second generation SAC II will make possible even further improvements. This article describes both generations of the SAC and gives an outlook on its future potential.

Operating the Oscilloscope; Setting up and Preliminary Adjustments
1965Although displays of quite considerable brilliance can be obtained on the screens of modern cathode ray tubes, it is nevertheless desirable to set up the oscilloscope where no direct light, either natural or artificial 57), will fall on the screen. To improve the contrast, a filter having a transmission characteristic corresponding to the spectral ...

An Operational Theory of Mental Health and Personal Adjustment
1961The formulation of an operational theory of mental health and personal adjustment in Chapter Twenty-two will be preceded by a summarizing discussion of its limitations and purpose. It will be stressed that no overall theory is proposed and that the formulation is meant to serve as a stimulus for further research and a guiding principle for mental ...
