  • Patent number: 8858751
    Abstract: A method for producing a flexible metal laminate includes continuously thermocompression-bonding laminate metal foils to a resin film. The thermocompression-bonding step is conducted by placing a protection metal foil between a pressure surface of a heat and pressure forming apparatus and the laminate metal foils. When the protection metal foil is subjected to an abrasion resistance test, in which the protection metal foil is placed such that a matte surface of the protection metal foil contacts a plate material having a surface equivalent to the pressure surface and in which the matte surface is rubbed against the surface of the plate material by applying a load to a shiny surface of the protection metal foil and pulling the protection metal foil, a streak is found on the matte surface only in a case where the load is over 500 g per area of 76 mm×26 mm.

  • Patent number: 6254661
    Abstract: An atomizing method for producing metal powder, including splitting molten metal in the vicinity of an exit of a nozzle by introducing the molten metal into a center of the nozzle, wherein gas is flowing through the nozzle. The split molten metal is then further split into fine particles by liquid ejected in an inverse cone shaped flow from a slit surrounding a lower side of the nozzle. The resulting powder is of fine size and spherical or granular shape, and is suitable for metal injection shaping.

  • Patent number: 6008151
    Abstract: The invention provides a nonmagnetic ceramic comprising 5% to 40% by weight of .alpha.-quartz and 5% to 60% by weigth of zinc silicate dispersed in 35% to 75% by weight of borosilicate glass as a matrix, the borosilicate glass having SiO.sub.2 and B.sub.2 O.sub.3 contents: SiO.sub.2 =70 to 90% by weight and B.sub.2 O.sub.3 =10 to 30% by weight. Using the nonmagnetic ceramic, multilayer ceramic inductors are obtained. When the ceramic is used as ceramic multilayer parts having an inductor section, it has a low dielectric constant and good characteristics in the high-frequency region, allows for low-temperature firing enabling the use of silver electrodes, prevents chip deformation and crack occurrence upon sintering, and provides a higher mechanical strength.
