摘要:
The device comprises a transmission mechanism (24) having a plurality of rotors (26) supported on a supporting means (12) at intervals and an endless member (28) trained over the rotors (26) to be operated by the rotation of at least one of the rotors (26), a drive means (16) for rotating one of the rotors (26), a guiding means (44) disposed along the endless member (28), a movable means (54) supported movably by the guiding means (44), and a means (30) for connecting the movable means (54) into the endless member (28) and mounted on the endless member (28) to move together with the endless member (28), so that the movable means (54) is reciprocated by the movement of the connecting means (30) when the drive means (16) is operated.
摘要:
In an information transmission system (10) including transmitters (12a, 12b, 12c), a receiver (14), and a transmission line (16) for transmitting information signals (30) from the transmitters (12a, 12b, 12c) to the receiver (14), the transmission line (16) is shared by the information signals (30) and external sync signals (42) which are adapted to synchronize the transmitters (12a, 12b, 12c) to each other. The external sync signals (42) have a voltage level higher than a maximum voltage level of the information signals (30) or lower than a minimum voltage level of the same, and are transmitted to the transmitters (12a, 12b, 12c) over the transmission line (16) by using blanking level portions of the information signals (30). The external sync signals (42) are separated from the information signals (30) based on their level difference and, then, applied to the transmitters (12a, 12b, 12c). Amplifier circuits (35, 36, 38) for blocking the propagation of signals toward the transmitters (12a, 12b, 12c) are installed in the transmission line (16), while bypass circuits (46) are connected to the transmission line (16) each in parallel to the associated amplifier circuit (35, 36, 38) so as to allow only the external sync signals (42) to be transmitted toward the transmitters (12a, 12b, 12c) based on a signal voltage level.
