Abstract: A structure of an ultraviolet light polarization component and a manufacturing process thereof, where a multi-layer thin film structure set is plated on a transparent falt substrate, and the multi-layer structure setis composed of a low refractive index thin film layer stacked for N times and a high refractive index thin film layer. The violet light is polarized into two polarization lights through the ultraviolet light polarization component, in which the two violet lights have a polarization ratio of larger than 10, so that the technical efficacy of realization of a small volume optical component and a large incident angle of the ultraviolet light.

Abstract: A piezoelectric vacuum gauge includes an actuator with a flexible portion, an actuating unit, a sensor unit, a signal input terminal and a signal output terminal, and a fixture unit having a base portion and a cover portion. An external signal is generated by a signal generator. Receive and transmit an external signal to an actuating unit by the signal input terminal so that the actuating unit has a vibration. Prompt a flexible portion by the actuating unit to produce a first resonant motion when the actuating unit having the vibration. The first resonant motion converts into a second resonant motion because the flexible portion is subject to a damping force of ambient air. Prompt a sensor unit by the second resonant motion to cause a shape transformation of the sensor unit to generate a detecting signal. Output the detecting signal to an external instrument by a signal output terminal of sensor unit to calculate a vacuum pressure value.

Abstract: This invention provides a geometrical structure configuration of maglev forces in a maglev rotational bearing apparatus. The bearing apparatus uses the magnetic forces as the suspension support for the rotational shaft, and utilizes a radial maglev support module to provide two maglev constraint forces perpendicular to and crossing on the axis of rotating shaft and an axial maglev support module to provide three maglev constraint forces parallel to the axis but non-coplanar. From the viewpoint of kinematical geometry, this machine has five linearly independent constraint forces so that the main axis is allowed to be suspended without contact and friction with static elements, and the suspension force in axial direction is better than currently available maglev bearings. The rotational shaft can be driven by a motor to perform high-speed rotational motion with noises free and vibrations free.
