Abstract: The multipurpose freight vehicle according to the present invention includes a lower deck capable of loading vehicles as freight thereonto, plural support posts standing up in an opposed state on both side edge portions of the lower deck, and an upper deck adapted to be lifted and lowered along the support posts. The support posts are supported so that they can be turned freely with respect to the lower deck in the direction of a vehicle width or in the longitudinal direction of the lower deck. The support posts are formed so that, when vehicles are not loaded onto the freight vehicle, the support posts can be housed in the lower deck by first lowering the upper deck, and then bringing down the support posts in the direction of a vehicle width or in the longitudinal direction of the lower deck. This enables when the freight vehicle is not loaded with freight the upper deck to be stored on the lower deck, and the support posts to be housed in an upper portion of or along side portions of the lower deck.

The medium protection data may include information for specifying restricted reproduction of portions of the original signal, such as by producing degraded resolution within specified regions of specified frames of a video signal.

Abstract: A vector block information indicating a plurality of line segment rows is read out from a block map. Each line segment row divides an area of a block from an area of a road in an image drawing region. Each point at which one end of a line segment row contacts with a boundary line of the image drawing region is set as a boundary point. In this case, a road crossing the boundary line of the image drawing region is indicated by a pair of line segment rows having a pair of boundary points close to each other. To determine an area of the road, the pair of boundary points are connected with each other through a connecting line segment. Therefore, a road area in the image drawing region can be automatically extracted from the block map.

Abstract: A digital data recording and reproducing apparatus includes a first recording medium having a first recording capacity, and a second recording medium having a second recording capacity greater than the first recording capacity. An input digital video signal is recorded on the first recording medium as an inward-flow signal. The inward-flow signal is transferred from the first recording medium to the second recording medium each time an amount of the inward-flow signal on the first recording medium reaches a first predetermined amount. The digital video signal is transferred from the second recording medium to the first recording medium as an outward-flow signal. The outward-flow signal is read out from the first recording medium as an output digital video signal. During a search, the outward-flow signal is read out from the first recording medium. During the search, monitoring is made regarding an amount of the outward-flow signal on the first recording medium which has not yet been read out.

Abstract: A digital broadcasting system capable of causing any of physical channels selected by a broadcaster to be received as one of the channels available to users which is different from the physical channel selected by the broadcaster. For each of programs of each of the channels available to said users, a program information record comprising PSI (program specific information) is stored in a data base. The broadcaster is permitted to include, in the PSI, channel mapping information whose mapping destination is a channel (or a program) to be received instead of the channel for which said program information is intended. The program information records is inserted in broadcast transport streams on schedule and, if necessary, immediately after the broadcaster have included the channel mapping information in the PSI data.

Abstract: A hemispherical dielectric resonator is arranged on a conductive substrate with a flat surface of the resonator in contact with the conductive substrate and fixed by a pair of fixing blocks. The dielectric resonator is fed with a signal feeder at a position at one side of the resonator such that intensity of the electric field is higher at that position. The fixing blocks contact a portion of the dielectric resonator where the intensity of the electric field is of a local minimum.

Abstract: A corkscrew (10) has a handle (12) mounted to a screw stem (14) rotatably guided within a cap (18) which contains upper ends of two prongs (40). The prongs have semi-circular lower ends (48) which surround a screw (16) and comprise inner shoulder stops (64) for engaging on a bottle-neck. Upper ends (42) of the prongs are articulated to a core unit (20) having a guide bush (22) for the screw stem (14). Cap (18) may be integral with the handle (12). Alternatively, the handle may be screw-fitted to a tapped stem (84) guided by the cap. Bearing means for the upper prong ends, on which expanding springs (65) bear, find stops at a lower peripheral edge of cap (18). A lug (50) supports each upper prong end (42) on a pin (34) that traverses a guiding cheek (30) on the guide bush (22). Radial bell ribs (44) have lower leading edges (45) in each central portion (46) of the prongs (40).

Abstract: According to a power control system for a CDMA mobile radio communication network, powers at which downlink pilot signals are transmitted from base stations are controlled so that the numbers of mobile stations managed by the respective base stations will be in a predetermined range. In addition, powers at which uplink signals are transmitted from the mobile stations are controlled so that communication qualities related to the uplink signals received by the base stations will converge on a predetermined threshold value. On the basis of the above-mentioned principle, the designing of cells in the CDMA mobile radio communication network is implemented.

Abstract: A message transfer service system comprising a data base for managing an address record for each user, message servers and clients served by the servers. Address data with which a recipient can be identified is used as a destination address. If there is only one address in an address record of the recipient, a message is sent to the address. If the address record contains a plurality of addresses, the addresses are sorted in order of priority based on destination specifying information, which may be registered in the address record by the recipient or specified by the sender. In this case, the message is sent to the highest-priority address. The format of message is converted according to the kind of terminal identified by the highest-priority address, if necessary. The server can execute a script received with a message. The server can generate a user interface by using interface components stored therein on the basis of application setting information.
