Abstract: A plurality of different fault locating functions are provided in a communication system comprising a plurality of terminals connected to a data transmission channel. The functions are at different levels, respectively, ranging from a level for rapid fault location to a level for reliable and sure fault location. Upon detection of an occurrence of a fault, one fault locating function is performed. If the fault is not located accurately located, another fault locating function of a level for more reliable is performed, thus the functions are performed sequentially in the order from the level for rapid location to the level for more deliberate and reliable location. Preferably, the channel is reconfigured to avoid the fault, according to the fault located by the functions of the respective levels. With this arrangement, a fault which does most possibly occur can be located quickly, while another fault difficult to locate can be located accurately.

Abstract: A pattern-evaluation aiding device evaluating a pattern of lines connecting nodes includes a memory unit storing a current voltage level applied to each of the nodes, a magnitude of a change in the current voltage level, and reflection coefficients for a reflection of the change. The reflection coefficients are provided for different values of the current voltage level and for different values of the magnitude. An operation unit calculates an updated current voltage level for each of the nodes based on the current voltage level, the magnitude of the change, and a corresponding one of the reflection coefficients.

Abstract: A data transmission method and system of a token passing type capable of periodically transmitting cyclic data produced in a station to other stations while enabling a packet data communication with high efficiency and without disturbing the periodicity of the cyclic communication. A token circulation time is set to be shorter than a cycle time for production of the cyclic data where no packet data to be transmitted. Also each station will pass an acquired token immediately to the next station if the station has no data to be transmitted. Thus, at least one station can have a token at least two times during the cycle time to transmit the cyclic data and the packet data. Upper limits may be set to capacities of the cyclic data and the packet data which are capable of being transmitted each time the token is acquired.

Abstract: A ring network data transmission system includes a plurality of transmission apparatuses, at least one terminal connected to each of the transmission apparatuses and double ring transmission paths interconnecting the transmission apparatuses in a ring-like system configuration so that terminals can communicate with one another through the associated transmission apparatuses. When a transmission fault occurs in the network, the transmission apparatus which can serve as the master station issues to all of the other transmission apparatuses a command for searching the fault location. In response to the reception of the command, each of the other transmission apparatuses sends out a monitor signal containing its own address and at the same time checks monitor signal received.

Abstract: A process for manufacturing polyurethane-coated products is disclosed. These polyurethane-coated products are manufactured by press-forming a metal material coated with a lubricant inclusive of a compound having an oxygen-hydrogen bond into a core member of a desired shape and covering necessary portions of the core member a with polyurethane foam or coating formed by reacting the compound with an isocyanate of the polyurethane forming material without degreasing steps, i.e. pretreatments for washing off the lubricant.

Abstract: In producing an article having a structurally primary part obtained by press-forming of a metal sheet to which a lubricant is applied beforehand and a secondary part stuck to the primary part with an adhesive, troublesome procedures for removal of the lubricant from the press-formed metal part precedent to adhesion-bonding of the secondary part can entirely be omitted without sacrificing the strength of adhesion between the primary and secondary parts by using an adhesive that has high chemical affinity with the lubricant remaining on the surface of the press-formed metal part. Preferably use is made of a solid lubricant containing organic polymeric substance as its principal component. In many cases the secondary part is made of a nonmetallic material, either an organic material or an inorganic material.

Abstract: Partial plating of a synthetic resin article is accomplished with a beautiful appearance and good adhesion of the plated coating regardless of the shape and size of the article or geometry of the intended coating by a method having the steps of (a) producing an article to be plated by uniting a first member, or members, of a conducting resin with a second member, or members, of a nonconducting resin such that the surface of the first member in the produced article is partially exposed and that the exposed portion of the surface alone gives a region, or regions, to be plated, (b) forming a metal coating exclusively on the exposed portion of the first member by chemical plating, and (c) effecting electroplating on the metal coating.
