Patent number: 5935267Abstract: Transmission and reception nodes are connected to a communication network to be controlled with respect to time according to bus time as time information shared therebetween. The transmission node periodically transmits data while keeping a predetermined free period of time. The reception node decides normality of data received. At detection of abnormality in reception, the reception node transmits during the free period of time a re-transmission request signal to the transmission node with specification of information identifying the bus time of the abnormal data reception. On receiving the re-transmission request signal, the transmission node obtains the data transmitted at the bus time identified by the information specified by the re-transmission request signal and then re-transmits the data during the free period of time to the reception node.Type: GrantFiled: April 9, 1997Date of Patent: August 10, 1999Assignee: Fuji Photo Film Co., Ltd.Inventor: Toshiaki Hayakawa
