A multi-tier limit-angle protection device detects a rotation angle about a rotation axis of a driving apparatus to thereby control the operation of a driving motor of the driving apparatus. The multi-tier limit-angle protection device includes a first-axis potentiometer for generating a first-axis sensing signal, a first-axis limit-angle detecting module for generating a first-axis confirming signal, and a controller. The controller effectuates a first tier protection mechanism by determining whether a limit angle of the rotation axis is exceeded according to the first-axis sensing signal, effectuates a second tier protection mechanism by determining whether the first-axis potentiometer is operating well according to a first-axis confirming signal, and effectuates a third tier protection mechanism through its control over the driving motor. The multi-tier limit-angle protection device features integration of software and hardware to thereby preclude mechanism complexity and provide a multi-tier limit-angle protection mechanism.

In a method and apparatus for evaporation depositing uniform thin films, a film is deposited on a substrate of a vacuum environment while maintaining a constant deposition rate. A cover is installed on a wall of the evaporation vessel. When the evaporation material is heated to an evaporation state and the interior of the evaporation vessel reaches a first vapor saturation pressure, the vapor of the evaporation material flows towards a pressure stabilizing chamber. When the pressure stabilizing chamber reaches a second vapor saturation pressure which is smaller than the first vapor saturation pressure, the vacuum environment has a vacuum background pressure which is smaller than the second vapor saturation pressure, so that the evaporation material vapor flows from the pressure stabilizing chamber towards the vacuum environment at constant rate due to the pressure difference, so as to evaporate the substrate.

Provided is a non-contact adjustable hysteretic magnetic encoder which includes a bipolar magnetic block, two magnetic sensing components, a storage, and a controller. After retrieving the current rotation angle by accessing a rotation angle table, the controller determines, by an encoding rule, digital logical values of a first phase signal (A-phase signal) and digital logical values of a second phase signal (B-phase signal) and outputs the digital logical values. The phase difference between a first phase signal and a second phase signal is adjusted, and a hysteresis range, also known as hysteresis angle, is adjusted, according to the grids attributed to the predetermined number of grids before the turning point and the grids attributed to the predetermined number of grids after the turning point. Hence, the non-contact adjustable hysteretic magnetic encoder features enhanced potential of expansion and marked industrial practicability.
