This paper presents the design and development of a laboratory-scale single axis solar tracking system. The chronological method was implemented into the system because it has high accuracy and can save more energy as compared to other types of solar tracking system. The laboratory-scale single axis solar tracking system can be used to identify the suitable and safe workspace for the installation of the actual solar tracking system plant. Besides, the validity of the laboratory-scale single axis solar tracking system was examined experimentally. The angle of rotation, per hour is preferable to be implemented into the designed laboratory-scale single axis sun tracking system due to the high performance ratio which is 0.83 and can save the energy up  to 25% during sunny days.

Automatic Testing System

By analyzing the test method named orthogonal 12 points for accelerometer, there are several problems to be solved in the temperature experiments for accelerometer. In order to study the temperature characteristics of the accelerometer for better, the testing system for accelerometer based on Labview is designed and the composition of the system is introduced. The microprocessor used in the temperature experiment is C8052F series microcontrollers. A 24-bit A/D converter is embedded in the microprocessor and the resolution of 0.149 microvolts can meet the accuracy requirements of the accelerometer. According to the requirements of high accuracy and test efficiency for accelerometer, the digital multi-channel testing technology is applied to realize the accurate test. The application in temperature experiments indicates that this precise and steady testing system can meet the requirement of accelerometer calibrating & testing completely.

Interesting Alternative

Magnetically suspended sensitive gyroscopes (MSSGs) provide an interesting alternative for achieving precious attitude angular measurement. But the high accuracy is sensitive to various disturbing torques acting on the rotor. In order to compensate for the drift errors produced by disturbing torques, this paper proposes a compensation system of Lorentz force magnetic bearings. Based on the geometric construction and running regularity of the compensation system, the analytical expression of the compensation torque has been deduced, and the generation mechanism of the compensation torque is revealed, which laid the foundation for the design of high-precision MSSGs. The common issues caused by disturbing torques can be effectively resolved by the proposed method in gyroscopes with a levitating rotor. To verify the feasibility and superiority of this compensation method, comparative simulations are carried out before and after the disturbing torques were compensated.

High Voltage Electron

The high voltage electron microscope has many advantageous features in comparison with the ordinary electron microscope. They are a higher penetrating efficiency of the electron, low chromatic aberration, high accuracy of the selected area diffraction and so on. Thus, the high voltage electron microscope becomes an indispensable instrument for the metallurgical, polymer and biological specimen studies. The application of the instrument involves today not only basic research but routine survey in the various fields. Particularly for the latter purpose, the performance, maintenance and reliability of the microscope should be same as those of commercial ones. The authors completed a 500 kV electron microscope in 1964 and a 1,000 kV one in 1966 taking these points into consideration. The construction of our 1,000 kV electron microscope is described below.
