Abstract: The invention is a frequency stabilized passive Q-switch laser, which has the advantages of small volume, simple structure, no need for high power voltage, etc. It has been a long time that timing jitter in conventional lasers is so large that they can not be applied to fields such as distance measurement. This invention utilizes an optical external modulation method to stabilize the repetition rate of the passive Q-switch, and thus to decrease its timing jitter. At the same time, the repetition rate of the Q-switch laser can be controlled by the same technology to meet various application needs.

Abstract: A light emitting diode package module structure comprises a LED module received in a reflection cup, a light transmitting color conversion member disposed on an annular surface of the reflection cup, a stationary package sleeved on the reflection cup in such a manner that the press portion of the stationary package is pressed against the light transmitting color conversion member, and the stop portions of the positioning legs of the stationary package are positioned against the bottom of the reflection cup. In this way, the light transmitting color conversion member is fixed to the reflection cup by the stationary package without the use of adhesive agents, which consequently simplifies the packaging procedure and reduces the package cost.

Abstract: A CNT-PI complex primarily includes polyimide (PI) and carbon nanotubes (CNT) dispersed in the polyimide. The method for producing the CNT-PI complex first disperses carbon nanotubes in a solvent by adding a dispersant and using an ultrasonic oscillator. Then the carbon nanotubes dispersion is mixed with polyamic acid to give a CNT-PI dispersion. The CNT-PI dispersion is then dried to form a film or layer of the CNT-PI complex. The dispersant used in this invention is an ionic liquid including organic cations and inorganic anions. The produced CNT-PI complex possesses good electromagnetic shielding effectiveness and presents better networked structures and electrical conductivity.

Abstract: A micro-electro-mechanical system (MEMS) microphone module and a manufacturing process thereof are described. A thickness of a transparent temporary cover plate temporarily disposed in a conventional plastic package structure is adjusted. After a mold for a plastic protector is formed, an UV ray is utilized to irradiate the mold to reduce adherence on the temporary cover plate and a back surface of the MEMS acoustic wave sensing chip. Then, the temporary cover plate is removed, and the left space left is the main source for the back-volume of the MEMS microphone. Finally, a tag is covered on the plastic protector, so as to define the whole back-volume and form a closed back-volume. In the above-mentioned process, the size of the back-volume is the same as an area of the whole MEMS microphone chip. In addition, the back-volume can be defined.
