A semiconductor component has at least one organic semiconductor layer. The component also includes at least one protective layer for at least partially covering the at least one organic semiconductor layer to protect against environmental influences. The at least one protective layer contains a proportion of an alkane with CnH2n+1 and n greater than or equal to 15 or consists entirely of an alkane of this type, or of a mixture of alkanes of this type. In one example, the protective layer is a paraffin wax. This creates a high resistance to moisture.

A MEMS-based optical steering apparatus for free space optical transmitters, receivers, and transceivers is disclosed. The MEMS device comprises actuators linked to an optic fiber, the actuators operable to maneuver the optical fiber in the X-Y plane at the focal point of the transmitter, receiver, or transceiver. The MEMS device may thus be used to replace gimbals for beam steering applications.

The invention discloses an active phased array transmitting-receiving component with high integration density. The phased array transmitting-receiving component is small in volume and high in integration density, and is realized through the following technical schemes: a phased array T / R component and a comparator are integrated in a high-frequency printed board through vertically interconnected radio frequency printed boards so as to form a high-density phased array T / R component integrated with the comparator; the phased array T / R component modulates and synthesizes radio frequency signals transmitted from antennas through the vector when working in a receiving mode R, and the radio frequency signal vertical transition is performed through the vertically interconnected radio frequency printed boards, and vector overlapping is performed on input radio frequency signals through the comparator, so that the input radio frequency signals after the vector overlapping are transmitted to an end machine to use; the T / R component performs vector modulation and amplification on the radio frequency signal transmitted from the end machine through the comparator, the vertically interconnected radio frequency printed boards and the phased array T / R component, and the radio frequency signal after the vector modulation and amplification is transmitted to the antenna so as to be used as an excitation source.

The invention discloses a tunnel convergence on-line monitoring apparatus based on torque-type included angle measurement. The apparatus includes an arch crown anchor base and two haunch anchor bases, wherein the arch crown anchor base is fixedly disposed on an inner wall arch crown of a tunnel supporting member and the two haunch anchor bases are fixedly disposed on two side haunches of the tunnel supporting member. A torque-type included angle measuring unit is installed on the arch crown anchor base and is tightened with the two haunch anchor bases through spring steel ropes. The apparatus is small in on-site occupied area, is easy to deploy, is easy to construct and operate, and allows large-scale and low-cost application.
