  • Patent number: 5502003
    Abstract: Reciprocal diffusion is prevented in a SiC electronic device by interposing an intermediate layer composed of W or a W-Si alloy rather than forming the Ni electrode directly on a SiC base, providing a stable electrode for which the contact resistance does not increase even when high temperatures are maintained. Bonding is facilitated when Au layer is formed on top of the Ni layer.

  • Patent number: 5501892
    Abstract: In a ceramic part having at least one small hole or both a hollow portion and small hole(s) which extends from the hollow portion to an outside, an edge portion of the small hole(s) is beveled. In a ceramic part having at least one small hole for a cooling mechanism through which a cooling medium is circulated, the surface roughness of an inner surface of the small hole is R.sub.max 7 .mu.m or below. Such a ceramic part having at least one small hole has no chipping or edge around the small hole(s) which can cause breakage at high temperatures and under high pressures, and is thus stronger than a conventional ceramic part. Such a ceramic part is suitable for use at a high temperature, for example, at 1000.degree. C. or above, and is particularly suitable as a gas turbine member, such as a turbine blade or a turbine nozzle of a gas turbine.

  • Patent number: 5497507
    Abstract: In a portable wireless telephone capable of providing a cellular mode which allows users to place or receive telephone calls through a cellular telephone network and a cordless mode which allows the users to place or receive telephone calls through an associated base unit of a cordless telephone, a battery condition is monitored to check whether or not the battery energy is so lowered that the cellular mode becomes inoperative. An LCD unit displays a warning if the battery energy is lowered down to such a low level. However, a micro computer equipped in this portable wireless telephone allows the users to use this portable wireless telephone as a cordless telephone, as long-as the remaining battery energy is sufficient enough to do so. Accordingly, this portable wireless telephone can be still activated in the cordless mode even if it cannot be no longer used as a cellular telephone.
