Abstract: An automatic rotating decoration includes a rotating body, a support, a driving device connecting the support, and a transmission member connecting the driving device and the rotating body. The support, the driving device and the transmission member all are received in the rotating body. An opening is defined in the rotating body. The support is exposed to the opening. The driving device includes a driving body and an output shaft extending from the driving body. The driving body includes a motor body and a battery seat electrically connecting the motor body. The automatic rotating decoration of the present invention may automatically rotate around the support on another object without additional housing thereby simplifying the structure of the automatic rotating decoration, increasing fun of the automatic rotating decoration and facilitating the handling.

Abstract: A method and device for monitoring the position of radioactive materials in vehicles relates to a technical field of monitoring of radioactive materials.

Abstract: The present invention relates to methods of preparing a library of compounds, wherein each of the compounds resides on the exterior portion and is encoded by coding tags confined in each of successive zones on the interior portion of a solid support. Following screening of the compounds, the coding tags can be cleaved, and then characterized by mass spectrometry.

Abstract: The alignment-free solid laser of the invention is characterized in that, an orientation prism having three inner surfaces perpendicular to one another, a bottom of equilateral triangle or circle shape, a corner apex located on the axis of the active material is located in front of one end of the active material and is used as a total reflective mirror of the resonant cavity, the other end of the active material is coated with a transitive-reflective film and is used as an output mirror, such that a laser resonant cavity is formed. This alignment-free solid laser has a simple structure, strong ability of misalignment-resistance, high stability, improved beam quality and reduced damage. Besides, it is easy to be operated and is easy to be standardized and modularized. It can be extensively used in military, industrial processing, medical and scientific research fields.
