Abstract: An optical transmission system including an optical transmission device and an optical reception device that receives, via an optical transmission line, a signal transmitted from the optical transmission device, the optical transmission system including a transmission-mode selection unit that selects transmission mode information in descending order of priority out of transmission mode information, which is combinations of a plurality of parameters concerning transmission performance, the transmission mode information being a plurality of kinds of the transmission mode information common to the transmission performance of the optical transmission device and the optical reception device, a signal transmission unit that transmits, to the optical reception device, a signal modulated based on the selected transmission mode information, and a signal reception unit that receives the signal and modulates the received signal based on the transmission mode information selected by the transmission-mode selection unit.

Abstract: A sealant discharging nozzle includes a nozzle body, a flat surface, a cutout, and a shaping portion. The flat surface is provided on the nozzle body and is formed on a discharge port side of a through hole that extends along a central axis of the nozzle body. The cutout is formed on a first side with respect to the flat surface. The shaping portion is, with respect to the flat surface, formed on a second side opposite to the first side.

Abstract: A joint has a plurality of synthetic resin hollow tubes inserted a plurality of resin-coated steel pipes which are formed by applying a coating resin on a surface of a thin wall steel pipe and are formed with at least one pair of fitting ribs extending in an axial direction on the coating resin for holding an edge of a partitioning body, in order to connect the resin-coated steel pipes in an intersecting fashion. The joint also includes slits which permit a pair of fitting ribs of the resin-coated steel pipes therethrough, are formed on reentrant side of at least adjacent two hollow tubes among a plurality of hollow tubes at positions in one plane extending across respective axes of the hollow tubes and extending over the entire length, and cover ribs which are formed integrally with the hollow tubes and extending along both sides of the entire length of the slits for covering outer side surfaces of a pair of fitting ribs of the resin-coated steel pipe.

Abstract: A power supply system having a primary control power line for supplying electric power to control systems indispensable to driving the vehicle from an electric power source. The power supply system is provided with an ignition switch cooperating with an ignition switch system so as to connect the electric power source to the indispensable control systems when an ignition key is turned to the ignition position and to disconnect the electric power source when the ignition key is turned to the off position. The power supply system also includes a subordinate control power line including a removable fuse for supplying electric power from the electric power source through the ignition switch system to at least those control systems indispensable to driving the vehicle.

Abstract: In a multiplex transmission system for use in a vehicle, a plurality of networks are interconnected via a gateway. In each individual network, electrical accessories that are mutually interrelated in terms of control are connected to the same transmission line.

Abstract: A multiplex data communication system including a number of communication nodes interconnected through a transmission path, each of which includes a data transmitting/receiving circuit providing a reception signal representative of normal data reception from another communication node and a transmission signal representative of normal data transmission therefrom, and a data operation circuit for controlling an electronic equipment unit associated with each communication node based on the data from the other communication node and generating the data relating to each communication node which is transmitted by the data transmitting/receiving circuit, the data operation circuit making a judgement of normality of a data communication function of each communication node based on at least one of the data reception signal and data transmission signal.

Abstract: A package containers rack frame for storing, transferring and displaying relative light-weight packages. The rack frame is constructed of a pair of side frames and a plurality of support bases which are removable from the side frames. The support bases are engaged into sockets on the side frame without disassembling of the side frames. The side frames have folding elements that are for controlling the distance between the side frames, which are folding and/or unfolding. The frame members of side frames has an adjusting member for adjusting the distance between the side frames, which thereby permits use of different width or height dimension for the containers. The support base has upward curved projections at both ends thereof for restricting in lateral movement of the containers.

Abstract: A vehicle multiplex transmission apparatus which can operate all the auxiliary units of a vehicle even when a power supply line of the vehicle is locally short-circuited. This vehicle multiplex transmission apparatus includes a plurality of control nodes arranged in respective portions of a vehicle, for controlling vehicle auxiliary units, and a multiplex transmission line for connecting among the plurality of control nodes. The control nodes are connected to a power supply node arranged at a predetermined position of a vehicle body through two independent systems of first and second power supply lines. The first power supply line supplies power to vehicle travel auxiliary units. The second power supply line supplies power to general system auxiliary units, but it can supply power to the travel auxiliary units as needed.

Abstract: An electrical wiring harness structure constituting a multiplex transmission network in a vehicle, in which a vehicle body is divided into a plurality of blocks, electrical components are mounted in units of blocks to constitute modules, and thereafter, the modules are combined to complete a vehicle body. The structure includes control nodes, arranged in units of modules, for controlling communications of the electrical components mounted on the corresponding modules, wiring harnesses, arranged between the adjacent modules, for forming a transmission path for performing communications among the control nodes, and connectors for connecting the wiring harnesses and the control nodes.

Abstract: A plurality of gateway nodes for connecting high- and low-speed networks as multiplex transmission lines include buffers for signal transmission and reception, communication ICs, and control units. A priority order in signal processing is set for these gateway nodes. Only a gateway node which operates normally and has the highest priority executes signal transmission between the high- and low-speed networks.
