A resonance drive actuator includes a casing; an electromagnetic drive section supported in the interior of the casing; a plunger to be reciprocatively driven at least in a rotational direction or in an axial direction by the electromagnetic drive section; an output shaft on which the plunger is fixed; and a spring which acts between the output shaft and the casing. The actuator resonantly drives a load connected to an end of the output shaft. The spring is a plate spring which integrally includes a casing inner-surface abutment portion fixedly abutting the inner surface of the casing, an output-shaft abutment portion fixedly abutting an outer surface of the output shaft, and a connection portion having the form of a strip and connecting the output-shaft abutment portion and the casing inner-surface abutment portion. The plate spring is fixed to both of the inner surface of the casing, and the output shaft.

This vibrating mirror element includes a pair of first beam portions supporting a mirror portion in a vibratile manner, a pair of second beam portions connected with the pair of first beam portions respectively, and a pair of driving portions connected with the pair of second beam portions respectively. The mirror portion is arranged in a region surrounded by the pair of second beam portions and the pair of driving portions. The width of the pair of first beam portions and the width of the pair of second beam portions are rendered smaller than the width of the pair of driving portions.

An electrical plug connector includes a first terminal module, a second terminal module, and a metallic contact member. The first terminal module and the second terminal module are received in a metallic shell. The metallic contact member is between the first terminal module and the second terminal module. The metallic contact member separates the first terminal module from the second terminal module. Moreover, two ends of the metallic contact member are respectively in contact with the ground terminals of the first plug terminals or in contact with the ground terminals of the second plug terminals.

The invention discloses a side surface polished open-loop PCF-SPR sensor. The side surface polished open-loop PCF-SPR sensor comprises a fiber core and a cladding covered outside the fiber core, wherein the fiber core is eccentric with the cladding, and the cladding is provided with air holes which are arranged in the axial direction of the fiber core; the air holes comprises a first air hole, a plurality of second air holes and a plurality of third air holes, the first air hole is arranged at the center of the cross section of the optical fiber, the second air holes surround the first air hole to form an annular N-angle structure with a layer number of K, and the third air holes are symmetrically arranged on two sides of the fiber core to substitute the positions of second air holes; theside surface of an optical fiber is provided with a polishing plane, and the polishing plane is provided with an open loop; and the open loop is covered with a sensing membrane, and the open ring is used as a sensing channel. By adopting a way of combining the side surface polished optical-fiber end surface and the open loop, the SPR sensing layer is most closest to the fiber core, so that substances with a refractive index less than 1.3 such as liquid oxygen, liquid CO2, fluorine-containing organic matters can be detected sensitively at a high amplitude or high wavelength and can be sensed byvirtue of multiple channels, so that the application range of the existing PCF-SPR sensor can be enlarged.

The invention discloses a paraffin sectioning method for Corydalis saxicola Bunting stems. The paraffin sectioning method comprises the following steps: sample fixation, dehydration, transparency treatment, wax dipping, embedding, sectioning and slice expansion, dewaxing, dyeing and slice sealing. The paraffin sectioning method specifically comprises the following steps: before the transparency treatment, putting dehydrated Corydalis saxicola Bunting stems into a 0.8%-1.2% sarranine solution, and carrying out dip dyeing for 8-12 hours; after the dewaxing, carrying out rehydration on a slide carrying the Corydalis saxicola Bunting stems, putting the Corydalis saxicola Bunting stems into an alcohol solution, carrying out color separation, simultaneously adding acetic acid into the alcohol solution for the color separation in a volume ratio of 1 to (800-1000), finally, putting the Corydalis saxicola Bunting stems into a 0.8%-1.2% fast green solution, and carrying out dyeing for 10-20 seconds. By virtue of the paraffin sectioning method disclosed by the invention, a clear Corydalis saxicola Bunting stem structure can be sectioned, a specimen can be stored for a long time for use, is a permanent microscopic slide specimen and can be applied to microscopic identification of Corydalis saxicola Bunting medicinal materials for market normalization.
