    Abstract: 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.

    Abstract: 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.

    Abstract translation: 提供一种球阀,其包括由具有延伸穿过其中的圆柱形孔的管状构件形成的阀体,其一端突出到孔中的杆和固定到杆的端部的球。 球具有直径从其中延伸的圆形孔,其中球是球形的,具有对应于孔的去除的弦节。 座位托架被插入孔中,座椅托架的一端靠近球,连接套与另一端相接触座椅托架,靠近球的端部,联管螺母将连接套筒连接到阀体上 。 在阀体的内表面上设置有直径相对的突起,延伸到孔中的突起,邻近其一端形成在座架的侧面上的凹部,并且在座椅支架的相邻侧面形成直径相对的槽 凹槽。 凹槽从相邻的凹部沿圆周方向延伸。 当座椅支架插入阀体并旋转时,阀体上的突起与座椅支架中的槽接合,从而将座椅支架保持在阀体中。 此外,凸缘形成在座架的另一端上,其中凸缘和阀体中的一个包括至少一个凸起,凸缘和阀体中的另一个包括至少一个空腔。 凸起接合在空腔中以防止座架相对于阀体旋转。
