Patent number: 5706422Abstract: 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.Type: GrantFiled: July 16, 1996Date of Patent: January 6, 1998Assignees: Hitachi Ltd., Hitachi Process Computer Engineering, Inc.Inventors: Hisayuki Maruyama, Jushi Ide, Seiichi Yasumoto, Sadao Mizokawa, Ken Onuki, Toshio Ishihara, Masato Satake, Toshihiko Uchiyama

Patent number: 5655108Abstract: 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.Type: GrantFiled: March 13, 1995Date of Patent: August 5, 1997Assignee: Fujitsu LimitedInventor: Toshihiko Uchiyama

Patent number: 5497374Abstract: 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.Type: GrantFiled: September 2, 1994Date of Patent: March 5, 1996Assignees: Hitachi, Ltd., Hitachi Process Computer Engineering, Inc.Inventors: Hisayuki Maruyama, Sadao Mizokawa, Seiichi Yasumoto, Ken Onuki, Hisao Ogawa, Junji Fukuzawa, Toshihiko Uchiyama, Toshiyuki Murakami, Osamu Anbo, Masato Satake

Patent number: 4855993Abstract: 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.Type: GrantFiled: February 22, 1988Date of Patent: August 8, 1989Assignee: 501 Hitachi, Ltd.Inventors: Takuji Hamada, Masahiro Takahashi, Katsuhiko Yoneda, Ken Onuki, Toshihiko Uchiyama

Patent number: 4398984Abstract: 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.Type: GrantFiled: June 10, 1981Date of Patent: August 16, 1983Assignee: Nissan Motor Co., Ltd.Inventors: Toshihiko Uchiyama, Eizo Yoshida, Toshiki Okuyama
