    摘要: A transmission or communication system, wherein plural individual elliptical orbits are so defined that an individual right ascension of a north-bound node is established with a designated angle. An artificial satellite is travels on a respective ones of the plural individual elliptical orbit and a group of artificial satellites arranged on respective ones of the plural individual elliptical orbits are used so that at least one of the artificial satellites having a communication system is always viewable within a pre-defined range of operational elevational angle in a zenith direction from a service area. The group of artificial satellites are on respective orbits obtained by combining an inclination angle and an eccentricity squared of the individual elliptical orbit so that a right ascension of north-bound node is a designated angle and a time period during which respective ones of the group of artificial satellites is viewable from ground is substantially identical.

    摘要: A method of and an apparatus for cutting a high-activity solid waste, such as a used channel box and a used control rod, to reduce same in size to facilitate its disposal. The channel box is cut axially through opposing corners to produce elongated split portions of an L-shaped in cross section, and the control rod is cut axially through a central portion to produce elongated split portions of an L-shape in cross section. The portions obtained by cutting the channel box and control rod are substantially similar in shape and facilitate storing.

    摘要: A method for collecting and processing information from a vehicle is disclosed. The information is useful for providing a loss-insurance coverage. The method includes the following steps: (a) Information is automatically transmitted from the vehicle to a central vehicle-information management center, the information including information regarding a position of the vehicle, information regarding control of the vehicle, information regarding states of parts of the vehicle, a type of the vehicle, and identification of a user of the vehicle. (b) The central vehicle-information management center computes a utilization service fee based on the type of the vehicle and the identification of the user transmitted in step (a). (c) The central vehicle-information management center transmits the computed fee and a request for confirmation to the vehicle. (d) The vehicle transmits a response to the central vehicle-information management center as to whether the user will effect insurance coverage.

    摘要: A method o gathering and analyzing vehicle information is disclosed. A central vehicle-information management center gathers first vehicle information gathered in real time, including position of the vehicle, control of vehicle, and conditions of vehicle parts, and gathers second vehicle information including vehicle type, vehicle identification number, and information regarding users of the vehicles. The central vehicle information management center performs a statistical analysis for the plurality of vehicles based on the first and second information. The first information is transmitted by a transmitter provided on each vehicle, and acquired via a satellite communication system and/or a land-based wireless communication system.

    摘要: An automatic nuclear fuel assembly replacing apparatus has a bridge and a trolley movable in X and Y axis directions, respectively. Mounted on the trolley is a nuclear fuel grapple movable in a Z axis direction and rotatable about the Z axis. A television camera mounting unit is also mounted on the trolley and movable in the Z axis direction. A control system of the apparatus moves the bridge and the trolley so that the center of an underwater television camera supported by the camera mounting unit is centered to a desired target position. Then, calculations are performed on the deviations of the position of the thus positioned camera and a target fuel assembly in the X and Y axis directions and about the Z axis, respectively. The thus calculated results are corrected by a deviation between the fuel grapple and the camera, whereby the position of the fuel grapple is finally controlled to be in alignment with the position of the target fuel assembly in the X and Y axis directions and about the Z axis.
