  • Patent number: 4651034
    Abstract: An analog input circuit, which samples and holds predetermined components sampled from input signals, has a filter and a sample and hold circuit which are formed as a unitary structure to simplify the circuit structure. For this purpose, the operational amplifier of the filter is constituted by two stages of voltage-follower circuits that are connected in series via a switch, and a holding capacitor is connected to the the switch. When the switch is closed, the holding capacitor assumes the same potential as the output of the filter and when the switch is opened, the holding capacitor maintains the output voltage of the filter.

  • Patent number: 4651317
    Abstract: A time division multiplex data transmission system. A particular time slot among those for data transmission is placed with alternation of different data modes such as "1" and "0" in a commanding station destined for issuing commands. The alternation of data modes is supplied to receiver stations together with other data. When alternation of data modes is detected at the particular time slot in the receiver station, the reception of one command signal from the commanding station is confirmed, while detection of disappearance of the alternation of data modes indicates other command. Since a fault in the data transmission system results in generation of a fixed data mode or level such as "1" or alternatively "0", the alternation of data modes and disappearance thereof can define the commands discriminatively from the state brought about by the fault. Fail-safe feature can thus be realized.
