Patent number: 5365350Abstract: A method for performing data communication between two circuits. Information is serially transmitted between two circuits. A first level change in one direction of a pulse signal output from one of the circuits to the other is determined as a reference time. A first data bit is determined to be a "1" or "0" in accordance with a time period from the reference time to a second level change in the one direction following the reference time. The second level change in the one direction as the reference time relative to the next bit of data in the pulse signal is then determined, whereby data of a predetermined number of bits are continuously transmitted.Type: GrantFiled: November 4, 1993Date of Patent: November 15, 1994Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Masahiro Kawasaki, Teruhiko Naruo, Yutaka Ohsawa, Isamu Hashimoto

Patent number: 5283663Abstract: A method is disclosed for performing data communication between a pair of circuits. The data communication is established by serially transmitting information which includes pulse signals. In executing the method, a reference time is determined as an instant of a first level change in a first direction of a pulse signal output from one of the circuits to the other. A judgement is made as to whether a first bit of data is a "1" or a "0" in accordance with a time period extending from the reference time to an instant of a subsequent level change in the first direction following the reference time. The instant of the subsequent level change in the first direction is determined as a reference time relative to the next bit of data in the pulse signal. The data of a predetermined number of bits is continuously transmitted by repeatedly establishing reference times and judging the value of a bit based on the time period which extends from the reference time to a subsequent level change.Type: GrantFiled: August 16, 1990Date of Patent: February 1, 1994Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Masahiro Kawasaki, Teruhiko Naruo, Yutaka Ohsawa, Isamu Hashimoto
