Abstract: A disclosed antenna device includes a plate-like ground plate, and a feeding unit that extends from the ground plate for a predetermined length at a predetermined angle. The feeding unit is constituted by a half-body, which is a body, such as a circular cone, halved by a plane perpendicular to the ground plate, and the feeding unit is prepared perpendicular to the ground plate.

Abstract: A path control packet is sent from a router to a receiver. The receiver capsulates the received packet and transmits a capsulated IP packet to a feed via a ground line. The feed extracts the path control packet by decapsulation and transmits the packet to a router. At the same time, path control information is sent to a satellite line. The router processes the packet as if the path control information from the router reached via the satellite line. When a receiver receives a packet via the satellite line, it transmits the packet as a packet to a router. This router processes the packet as if the path control information from the router reached via the satellite line.

Abstract: A balanced-armature type polar relay (10) capable of assuring, by its own structure, sufficient insulation distances, meeting the requirements of IEC60950, when mounted on an electric communication line connecting equipment, wherein a maximum distance between one movable contact and one fixed contact capable of being brought into contact with each other during the travel of an armature is set at 1 mm or more, and at least one of the abutting surfaces of the armature and the core polar surfaces of the electromagnet opposed to the abutting surfaces is formed as an inclined surface to reduce an angle of opposed surfaces at the time of mutual abutment to as little as possible, whereby the armature passes, during the travel thereof, a position where each of the pair of abutting surfaces faces the pair of corresponding core polar surfaces in parallel with each other.

Abstract: A data path control device with a first interface section for connecting to a LAN, second interface section for connecting to an external network through a small transmission capacity two-way line such as a telephone line, and third interface section for receiving a large capacity data from a large transmission capacity one-way line such as a satellite broadcast line. The data path control device changes the sender address of the data transmitted from a computer to a network based on a previously set correspondent relationship, thereby controls the path so that the large capacity data from the network is transmitted through the large transmission capacity one-way line. A path of the reply data from a network responsive to the request data from a computer outputted to an external network is selected by the computer side, and in the case that the reply data is composed of large capacity data, a satellite line having a large transmission capacity can be selected.

Abstract: Data receiving device and method in which data is received through a broadcast network, the data is reconstructed into packets usable on a computer, and the packets are output to the computer, directly or through a local area network. The reconstructed packets are preferably in the format of Internet Protocol (IP) packets. A destination address allocated to the data receiving device on the broadcast network is converted, via the data receiving device, to an IP address allocated to a personal computer on the Internet.

Abstract: A switch operable under a predetermined condition includes a plurality of switch parts each including a pair of reed pieces and a connecting member of an electrically conductive non-magnetic material via which the plurality of switch parts are serially connected. The switch operates only under a condition where all of the plurality of switch parts are operated by external magnetic fields individually and simultaneously acting on the plurality of switch parts.

Abstract: A packing band having a superior weld is disclosed. The band can be made of a stretched thermoplastic resin having a flat cross section. The weld is formed by overlapping ends of the band extending in the lengthwise direction thereof. The weld portion of the band includes a plurality of welded sections separated by at least one non-welded section along the lengthwise direction of the band. The welding of the packing band can be accomplished by overlapping parts of the band in a lengthwise direction thereof; melting discontinuous portions of the parts in a pattern along the length of the band parts of a melted portion, an unmelted portion and a melted portion; and then pressing the parts together so that the melted and unmelted portions of the parts contact each other and form a weld.

Abstract: A compound represented by formula (I): ##STR1## or a pharmaceutically acceptable salt thereof is provided, which has an excellent antitumor activity.

Abstract: In a color video signal processing circuit for use in processing two chrominance component signals produced on the reproduction side of a video tape recorder, in which two chrominance component signals have been time compressed and successively recorded in cyclically repeated fashion as one series of chrominance signal, such a signal is time expanded and made into two series of chrominance signals on the reproduction side. Each of the two series of chrominance signals, i.e., the current signal, and the signal 1H before each are subjected to digital processing for detection of a correlation therebetween and an arithmetical mean value of both the signals is output when there is such a correlation and also the level of the current signal is higher than a reference level, whereas the current signal is output as it is when the level of the current signal is lower than the reference level or when there is no such correlation even if the level of the current signal is higher than the reference level.

Abstract: A method for constructing a blast furnace, in which the blast furnace is designed to be divided into a plurality of blocks with a deck frame and other parts, and these blocks are individually assembled on the ground in a sequential order from the furnace top to the furnace bottom. The individual blocks are conveyed one after another onto a foundation, and the furnace top block is initially lifted up. In this manner, the successive blocks are lifted up in the described order and joined together at their ends to complete the blast furnace.
