Abstract: The present invention provides a resin composition comprising: 1 to 20 parts by weight of a reinforcing fiber; 0.2 to 5 parts by weight of an anti-settling agent; 20 to 40 parts by weight of an epoxy resin; 0.1 to 3 parts by weight of a curing agent; and 50 to 75 parts by weight of a high dielectric constant filler. The present invention further provides a dielectric layer produced from the resin composition and a capacitor comprising the dielectric layer. In the dielectric layer made from the resin composition provided by the present invention, the fibers can be evenly dispersed and can enhance the mechanical strength of the resin composition, and cooperate with the epoxy resin to bring excellent toughness. Therefore, the mechanical strength of the produced dielectric layer can be remarkably improved, and its fragility can be effectively overcome when the dielectric layer is used in the PCB double-side etching process.

Abstract: A sheet electrode with a predetermined thickness for an electric double layer capacitor is made by carrying out a roller rolling step in which a long sheet intermediate is made from a material containing a carbonaceous powder, a conductive assistant and a binder and thereafter. The sheet intermediate is passed between a pair of rolling rollers to be wound up by a winding section while being drawn out of a drawing section. The roller rolling step includes drawing the sheet intermediate out of the drawing section under a predetermined tension applied to the sheet intermediate, and controlling a widthwise position of the sheet intermediate immediately before the rolling rollers by an edge position controller, and winding the sheet intermediate rolled by the rollers onto a winding section while the winding section is applying a predetermined pressure to a rolling side drive roller located adjacent to the winding section and rotated at a predetermined speed.

Abstract: Different from conventional so-called mix-type film capacitors involving several disadvantages, in which the dielectric layers consist of a combination of a dielectric plastic resin film and an insulating paper sheet, the invention provides an all-film oil-impregnated capacitor in which the dielectric layers consist only of a plastic resin film such as a biaxially oriented polypropylene resin film (OPP film) suitable for use in microwave ovens. The all-film capacitor of the invention can be obtained and has satisfactory properties only when prepared by using specified materials including the OPP film, aluminum foil and capacitor oil and under specified conditions relative to the dielectric tangent values and dielectric capacity values before and after impregnation with a capacitor oil as well as the conditions in the step of oil impregnation.

Abstract: A capacitive element for a circuit board or chip carrier is formed from a pair of conductive sheets having a dielectric component laminated therebetween. The dielectric component is formed of two or more dielectric sheets, at least one of which can be partially cured followed by being fully cured. The partially cured sheet is laminated to at least one other sheet of dielectric material and one of the sheets of conductive material. The total thickness of the two sheets of the dielectric component does not exceed about 4 mils and preferably does not exceed about 3 mils. The use of two or more sheets of dielectric material makes it very unlikely that two or more defects in the sheets of dielectric material will align, thus greatly reducing the probability of a defect causing a failure in test or field use.

Abstract: An electrostatic pin chuck consisting of an annular array of gas inlets, located towards the periphery of the chuck, for providing a uniform distribution of cooling gas to a wafer held by the chuck. This uniform distribution of cooling gas results in a uniform transfer of heat from the wafer to the chuck. Two annular rims positioned towards the outer perimeter of the chuck, and separated by an annular array of vacuum pumpout ports connected through a manifold to a vacuum pump, help to prevent leakages of cooling gas by functioning as gas bearing seals. Varying the annular thickness of the inner and outer rim, vacuum pump pressure, and the space between the wafer and chuck all affect the leakage rate of cooling gas from the chuck.

The electrode segments of the second electrode are physically separated from other electrode segments. The capacitors further include an interconnection bus electrically coupling the electrode segments of the second electrode. Selective isolation of one or more electrode segments permits isolation and bypass of any defects identified in those electrode segments.

Abstract: When forming a zinc-deposited base material for metallized capacitors, a primer layer for zinc-deposition made from at least one compound selected from the group comprised of an oxide of silicon, titanium and zirconium is formed on at feast one side surface of a base body comprised of a film or a thin condenser paper. Next, a zinc-deposited layer is formed on top of the primer layer. Then, a protective layer made from at least one compound selected from the group comprised of silicon-based oil, fluoro-based oil, alkylnaphthalene, polydiphenylether, fatty acids, fatty acid salts and paraffin wax is formed on top of the zinc-deposited layer. In this way, it becomes possible to form a zinc-deposited base material having excellent moisture resistance when used for metallized capacitors.

Abstract: This capacitor assembly includes inner and outer sheets of metal foil constituting first and second electrodes, respectively, of the assembly and dielectric film interposed between the foil sheets and insulating the foil sheets from each other when the capacitor assembly is energized. The foil sheets and the dielectric film are wound about a central axis to form a roll in which the sheets and the film are disposed in interleaving turns extending about the central axis in face-to-face relationship. Each of the foil sheets has a head edge near the central axis and a tail edge near the outer periphery of the roll. The head and tail edges of the inner foil sheet are folded over to reduce electric-field stress concentrations adjacent these edges. But the head and tail edges of the outer foil sheet are left unfolded, and the outer foil sheet adjacent its head and tail edges extends about the central axis substantially beyond the respective head and tail folded edges of the inner foil sheet.
