    摘要： An improved PTC device and method of manufacturing is disclosed. In one embodiment, the device and method incorporates an improved metal-ceramic composite PTC material manufactured by: (a) heating a ceramic material to a sufficiently high temperature to induce the ceramic material's PTC properties; (b) grinding the ceramic PTC material into a powder; (c) mixing the ceramic PTC material powder with a metal material powder so as to produce a metal-ceramic composite material powder; and (d) sintering the composite material powder at a temperature between 600° and 950° C. In alternative embodiments, an improved multi-layer structure and method of manufacturing such a structure is disclosed. In various embodiments, a PTC device made in accordance with the improved multi-layer structure and method of manufacture may or may not incorporate the improved metal-ceramic composite PTC material disclosed herein, but may use conventional ceramic-based PTC materials.

    摘要： A composite fuse element includes a network or matrix of conductive material that is in contact and interspersed with arc suppressing materials at a particle level. In such a matrix, the conductive (e.g., metal) network and the arc suppressing material particles provides a large contact surface area between these materials. When the conductive network melts or vaporizes, the resulting conductive vapors are adsorbed into the arc suppressing particles in a short time due to the large contact area between conductive and arc suppressing materials and the short diffusion distance that the conductive vapors are required to travel before they are absorbed by the arc suppressing material.

The glass ceramic consists of 15-35% by weight of lead-free borosilicate glasses with low softening point, 15-35% by weight of lead-free borosilicate glasses with high softening point, 20-80% by weight of combination of amorphous and crystalline SiO2-filler (preferably 5-30% by weight of amorphous SiO2, 10-50% by weight of crystalline SiO2) and 0.1-10% by weight of at least one oxide of Al2O3, BaO, Sb2O3, V2O5, CoO, MgO, B2O3, Nb2O5, SrO and ZnO. The glass ceramic can be densified up to 99% of its theoretical density after firing and is co-firable with conductive metals between 800-900° C.

    摘要： A multilayered electronic component with or without inter-layer connections created by a process using radiation curing such as ultraviolet/electron beam curing techniques. UV light or electron beam curable binders are mixed with ceramic powders and metals powders to form a ceramic slurry and electrode ink, there is little or no solvent in the metal ink and ceramic slurry. Instead of drying, a UV or electron beam is used for curing the binders. These binders could contain UV/electron beam curable monomers or oligomers, photo initiators, and other additives to provide the desired chemical and physical properties in the forming process.

    摘要： An apparatus for electroplating small parts comprises an electroplating bath for holding an electrolyte and electroplating anodes. The apparatus includes a container having at least one screened parts compartment for holding the parts to be electroplated, and incorporates an electrically conductive screen as its base portion, on which the parts are settled. The conductive screen is adaptable to be connected to the negative pole of a power supply to function as the cathode. A pump circulates freshly ionized electrolyte into the parts compartment and directs a flow of the electrolyte to periodically tumble the parts in the parts compartment. Thereafter, the parts are shaken by a shaker to level the parts to maximize the surface and electrical contact between the parts and the screen when they are settled on the screen. In alternative embodiments of the invention, the container can be of perforated panel construction. Also, the container can include a divider to partition the container into a plurality of parts compartments for electroplating a variety of different parts.
