Abstract: Systems and methods directed to the use 1002F to build microdevices and biomedical devices. Through the addition of a photosensitizing agent, Epon epoxy resin 1002F can be linked in the presence of UV light, making it useful as a photoresist or as a micropatternable structural material. One embodiment comprises combining 1002F monomer resin with a solvent and a photoinitiator, placing the monomer solution on a surface, exposing the monomer solution to UV light through a mask to initiate linking, and stripping the unlinked polymer away. In another embodiment, 3-D structures are built using two or more layers of sensitized monomer films, each having different sensitivity to light, and the use of a mask containing opaque and semi-opaque regions.

Abstract: A heat dissipating device includes a base, a heat pipe and a fixing member. The base includes an accommodating recess and two restraining portions, wherein the two restraining portions are located at opposite sides of the accommodating recess and an opening is between the two restraining portions. A first end of the heat pipe is disposed in the accommodating recess such that a bottom surface of the first end is exposed out of the opening, wherein a width of the opening is smaller than a maximum width of the first end. The fixing member is disposed on the base such that the first end of the heat pipe is fixed between the fixing member and the two restraining portions.

Abstract: A heat-dissipating device includes a plurality of fin plates arranged adjacently to each other, a heat pipe and a cover board. Each fin plate has at least two fixing tabs protruded from a top edge thereof, and a supporting portion formed between the fixing tabs. An accommodating space is defined between the supporting portion and the fixing tabs. The heat pipe has a portion disposed in the accommodating space. The cover board is formed with a plurality of slits corresponding to the fixing tabs. The fixing tabs pass through the slits and fixed to the cover board.

Abstract: The present invention discloses a method for producing metal nanoparticles, in which a metallic compound is first dissolved in a solvent to obtain a metal ionic solution, then the metal ionic solution is uniformly distributed on the carrier, and finally electrons provided from an electron source are shot at the carrier for reducing the metal ions to the metal nanoparticles.

Abstract: The present invention provides a structure of an evaporation region of an absorption diffusion type refrigerating circulation. The refrigerating circulation comprises a generator, a rectifier, a condenser, an evaporator, a concentrated ammonia aqueous solution tank, and an absorber. An ammonia liquid pipe and a hydrogen pipe are arranged in a pipeline of the evaporator. The evaporator at the evaporation region has a simple shape and structure, and can be processed easily, hence saving the space thereof. Because the ammonia liquid pipe and the hydrogen pipe are arranged in the evaporator, the effect of heat exchange thereof is better, and the refrigerating temperature is lower.

Abstract: An absorption diffusion type refrigerating structure comprises a generator, a rectifier, a condenser, an evaporator, a concentrated ammonia aqueous solution tank, and an absorber. The absorber is vertical. A spiral device is disposed in the absorber to lengthen the flow path of diluted ammonia aqueous solution, to extend the time of diluted ammonia aqueous solution in the absorber, and to expand the reaction area of diluted ammonia solution in the absorber, thereby reducing the whole weight, shrinking the volume, and enhancing the refrigerating speed. An ammonia liquid pipe and a hydrogen pipe are arranged in the evaporator. The evaporator has a simple and symmetrical shape, and can be processed and assembled easily, hence saving the space thereof. Moreover, because the ammonia liquid pipe and the hydrogen pipe are arranged in the evaporator, the effect of heat exchange thereof is better, and the refrigerating temperature is lower.

Abstract: The present invention proposes a concentrated ammonia aqueous solution tank used in an absorption diffusion type refrigerating equipment. The present invention is characterized in that a capillary tissue is placed in the concentrated ammonia aqueous solution tank. The capillary tissue is formed by bending knitted metal nets or is integrally formed by means of sintering. Thereby, additional surface area of absorption reaction can be increased, and the volume and weight of the original absorber can be reduced, hence increasing refrigerating speed and reducing refrigerating temperature.
