Abstract: A multi-pole, three-phase rotary electric machine includes a multiplicity of armature windings provided on a stator. Respective one ends of the armature windings are external connection ends that are connected with one another in three phases, while respective other ends of the armature windings being neutral ends that are all connected together with one another. The external connection ends of the multiplicity of armature windings are located on one axial side of the stator, and the neutral ends of the multiplicity of armature windings are located on the other axial side of the stator opposite the external connection ends.

Abstract: A router interposed between a subnet and a backbone network, where the subnet includes a plurality of layer 2 switches and a plurality of terminals. The terminals communicate with each other via the layer 2 switches and a master router, wherein the router connects to the master router, the subnet and the backbone network, and originally operates as a backup router, but can be transitioned to operate as a redundant master router. The router includes a severance detection unit for detecting severance between the layer 2 switches and a redundant function control unit which, when severance has been detected: (i) resumes interrupted communication between the backbone network and the subnet via the router, (ii) receives, from the master router, a copy of an address resolution protocol (ARP) table, and stores the copy of the ARP table in the router, and (iii) transitions the router into a redundant master router.

Abstract: A column (10) of the present invention includes a tube and at least one columnar separation member (12) disposed inside the tube. The separation member (12) is a vitreous porous body, and the tube is an elastomer tube (11). A cartridge column (30) of the present invention includes the column (10) and a housing (40) for holding the column.

Abstract: A router is interposed between a subnet, configured of a plurality of layer 2 switches, which relay an ARP response packet and learn an MAC address, and a plurality of terminals, and a backbone network. The router has a severance detection unit; an ARP transmission/reception unit which transmits an ARP request packet to an intra-subnet route and a backbone network route. The ARP request packet requests an MAC address for an IP address of each of the plurality of terminals. The ARP transmission reception unit receives an ARP response packet, which has the MAC address of the terminal as a transmission source. An ARP response forwarding unit generates a learning packet which has the MAC address of the terminal, stored in the ARP response packet, and forwards the ARP response packet to a route, a reversal of a route by means of which the ARP response packet has been received.

Abstract: A plurality of distribution devices accommodate one or more respective cameras. Respective picture monitors are connected to a plurality of receiving devices. The plurality of distribution devices and the plurality of receiving devices are connected by a transmission line. This transmission line is in a ring shape, and transmits picture data by a time division multiplex method. On receipt of a request related to picture display from a user terminal, a central device transmits an instruction to the plurality of distribution devices and to the plurality of receiving devices, according to a usage condition of the transmission line and the number of simultaneously distributed pictures. The plurality of distribution devices distribute picture data according to the instruction, and the plurality of receiving devices receive the picture data according to the instruction.

Abstract: A video telecommunication system having a plurality of cameras (video cameras) installed at remote locations and a monitor for monitoring the video, provided with a video information describing unit for sending a switch command for the camera to a video transmission apparatus, simultaneously sending character information describing the video information of the camera in accordance with the switch command, and having the video information and the character information displayed on the monitor, whereby it is possible to easily record, change, and correct character information on the place name etc. combined with the video information.

Abstract: The present invention relates to a binding band (1) for a wire harness diverging portion, which is used for binding a diverging portion having a trunk portion (TL) formed by gathering plural wire harnesses (WH) and a branch portion (BL) branching from the trunk portion.

Abstract: In order to reduce the required storage capacity as well as the processing time in a delay route searching technique for logical circuits, a fan-out direction delay time calculating means 22 figures out, for each component of a logical circuit, the worst transit time from the starting point; and a fan-in direction delay time calculating means 23 figures out, for each component of the logical circuit, the worst remaining time from that component to the end point.

Abstract: An optical information recording and reproducing apparatus includes a random information generating section for generating predetermined random information. A recording information generating section generates recording information on the basis of non-DC-free information and the predetermined random information. A synchronization sensing section senses a synchronization information. A recording section records the recording information in the recording area of a recording medium, on the basis of the synchronization information. A reproducing section reproduces the recording information recorded by the recording section.

Abstract: An information signal reproducing circuit for use in an optical information recording/reproducing apparatus, includes a photo detector, a plurality of amplifiers and a plurality of couplings for connecting the amplifiers to each other in a serial manner. A gain of a signal produced by the photo detector is decreased only for a time period during which information is recorded or erased in the information recording/reproducing apparatus. Therefore, in case the amplifiers are serially connected to each other by means of AC couplings, information signal can be correctly read out without being influenced by transients of capacitors constituted of the AC couplings. In case the amplifiers are serially connected to each other by means of DC couplings, information signal can be correctly read out without causing a latch up.

Abstract: In an optical information recording and reproducing apparatus for recording and reproducing information by controlling the focus of an optical system for condensing and projecting lights of a light source onto a recording medium, an offset part produced in case the lights are condensed and projected in a focus servo state in data writing regions in the recording medium and prepit regions which are adjacent to the data writing regions and in which discriminating codes are written is detected in the respective format regions by a format detecting means and an offset fluctuation controlling voltage is impressed on the basis of this detecting signal to inhibit the fluctuation of the offset in the respective regions of different formats.
