    摘要: A wireless communications apparatus used in a wireless communications network consisting of multiple wireless communications apparatuses mutually connected via wireless links includes (a) a buffer configured to temporarily store information received from an adjacent wireless communications apparatus or a user terminal located under the wireless communications apparatus; (b) a routing control information processing unit that estimates a node cost representing traffic at the wireless communications apparatus and a link cost representing a radio condition of the link to determine a transmission route based on cost information reflecting both the node cost and the link cost; and (c) a routing control unit that designates a next hop to which information accumulated in the buffer is to be transmitted according to the determined transmission route.

    摘要: Production of hollow carbon fibers and hollow carbon particles includes baking and carbonization of polymer particles having a specified volume after deformation. A metal-deposited carbon fiber with metal deposited inside and/or outside the hollow carbon fiber is applicable to electron discharge devices. The thickness and crystallinity of the graphite layer can be freely controlled. Since almost no by-product is generated, separation and refining using a solvent is not required. A hollow carbon particle of desired shape can be produced at a high yield rate. The hollow carbon fiber represented by a carbon nano-tube can be controlled in such a way that a low resistance and uniform shape are provided so that there is an increase in the amount of electrons discharged from the hollow carbon fiber. Use of this hollow carbon fiber as an electron discharge source provides an excellent electron discharge device characterized by stable pixels.

    摘要: A ball valve is provided which comprises a valve body formed from a tubular member with a cylindrical hole extending therethrough, a stem having one end thereof projecting into the hole, and a ball fixed to an end of the stem. The ball has a circular bore extending diametrically therethrough, wherein the ball is spherical in shape with removed chordal segments corresponding to the bore. A seat carrier is inserted in the hole, the seat carrier having one end adjacent the ball, a connecting sleeve contacts the seat carrier at the other end thereof opposite the end adjacent the ball, and a union nut couples the connecting sleeve to the valve body. Diametrically opposed projections are provided on the inner surface of the valve body, the projections extending into the hole, recesses formed on the side of the seat carrier adjacent the one end thereof, and diametrically opposed grooves are formed in the side of the seat carrier adjacent the recesses. The grooves extend in the circumferential direction from the adjacent recesses. When the seat carrier is inserted into the valve body and rotated therein, the projections on the valve body engage the grooves in the seat carrier to thereby hold the seat carrier in the valve body. Further, a flange is formed on the other end of the seat carrier wherein one of the flange and valve body includes at least one projection and the other of the flange and valve body includes at least one cavity. The projection is engaged in the cavity to prevent the rotation of the seat carrier with respect to the valve body.
