Abstract: An ear canal clamp for small animals includes a base and a clamping mechanism. The clamping mechanism includes two clamping arms movably mounted on the base, a biasing member mounted on the base and constrained between the clamping arms, and two ear canal positioning members mounted respectively to the clamping arms and facing each other. The clamping arms are configured to move toward each other and compress the biasing member to increase the distance between the ear canal positioning members. A biasing force generated by the biasing member when compressed is used to push the clamping arms to move oppositely with respect to each other.

Abstract: A semiconductor structure is provided and includes a first gate structure, a second gate structure, and at least one local interconnect that extend continuously across a non-active region from a first active region to a second active region. The semiconductor structure further includes a first separation spacer disposed on the first gate structure and first vias on the first gate structure. The first vias are arranged on opposite sides of the first separation spacer are isolated from each other and apart from the first separation spacer by different distances.

Abstract: The present application provides a testing apparatus. The testing apparatus includes a base; a first printed circuit board, disposed above the base; a stiffener, disposed adjacent to the base, located at a center of the base and passing through the first printed circuit board; a second printed circuit board, disposed at a center of the stiffener; and a probe card, one part thereof disposed adjacent to the stiffener and the other part thereof passing through the base, the first printed circuit board, the stiffener and the second printed circuit board. The base, the stiffener and the second printed circuit board are integrated and the base carries the first circuit board.

Abstract: A printing material for a three-dimensional (3D) printing apparatus is provided. The printing material includes a core and a shell covering the core, wherein the Shore hardness of the core is A45-A90, the Shore hardness of the shell is D40-D85, the Shore hardness of the shell is higher than the Shore hardness of the core, the volume percentage of the shell is 10% to 30%, and the volume percentage of the core is 70% to 90%. Since the printing material has a specific structure, feed abnormality during the printing material passing through a narrow inlet hole and guide tube may be prevented in the use of low-hardness material as the core.

Abstract: A fuel cell unit of a proton exchange membrane fuel cell system includes a pair of flow field plates and a membrane electrode assembly. The membrane electrode assembly is interposed between the pair of flow field plates to define respective reactant flow channels with the pair of flow field plates. The membrane electrode assembly includes an anode catalyst layer, a cathode catalyst layer, a proton exchange membrane and a pair of gas diffusion layers. The gas diffusion layers are respectively disposed adjacent to the anode catalyst layer and the cathode catalyst layer and face to the flow field plates. At least one of the gas diffusion layers has a fluid permeability distribution profile increasing first and then decreasing from an inlet to an outlet of the reactant flow channel. The gas diffusion layer has the maximum fluid permeability at the site with the highest rate of reaction.
