摘要： In a measuring differential amplifier having first and second input terminals for subtracting a first signal applied to the first input terminal from a second signal applied to the second input terminal to obtain a subtraction and for outputting a signal corresponding to A times of the subtraction, a circuit for reducing an offset generated during measurement. Prior to the measurement, the second signal is applied to the first and second input terminals so that the differential amplifier outputs a voltage corresponding to A times of a difference between the second signals, i.e., A times an offset voltage. At this time, the differential amplifier is connected at its output terminal to one end of a capacitor grounded at the other end so that the voltage corresponding to A times of the offset voltage is applied to the capacitor for charging. During the measurement, the output terminal of the differential amplifier is disconnected from one end of the capacitor so that the voltage charged in the capacitor is applied to the adder and multiplied by 1/A to become again the offset voltage. The adder adds a signal indicative of the offset voltage to the first signal to obtain an addition signal and supplies the addition signal to the first input terminal of the differential amplifier. Thus, the input offset voltage is canceled by an offset voltage newly generated at the differential amplifier.

摘要： An apparatus for carrying out serial control and a method of controlling the apparatus wherein the apparatus and the method are employable for a centralized control system for various machinery such as press, machine tool, ship, aircraft or the like machine as well as a centralized control system for unmanned conveyor, unmanned warehouse or the like installation. The apparatus comprises a plurality of nodes connected in series one after another and a main controller connected to the nodes. A data row length of data included in a signal from the node at the preceding stage is counted by a data row length counter and the counted data row length is compared with data row length data included in the signal from the node at the preceding stage. When the counted data row length does not coincide with a data row length representative of the data row length data, this non-coincidence is determined as a data row length abnormality thereby to generate an error signal. The data row length data included in the signal from the node at the preceding stage is converted into data row length data corresponding to a row length of data outputted from own node and the converted data row length data are delivered to the node at the subsequent stage.

摘要： A novel encoding method which facilitates handling at the time of demodulation (decoding) and is capable of further alleviating a burden imposed on a demodulation (decoding) circuit. When an input NRZ code signal is at, for instance, a logical "0" level during a given unit bit time, encoding is effected to obtain a signal having the same form as that of a CMI code such that the signal is set to a logical "1" level in correspondence with a first half of the unit bit time, and to the logical "0" level in correspondence with a second half thereof. Similarly, when the input NRZ code signal is at the logical "1" level during a given unit bit time, encoding is effected to obtain a signal such that the signal is unfailingly set to the logical "1" level during its initial bit time, and thereafter only during a bit time when the NRZ code signal is at the logical "1" level during the unit bit time, the logical "1" level and the logical "0" level are alternately repeated for each unit bit time. By virtue of this encoding, a maximum interval between adjacent signal rise or fall timings is reduced to a bit time of two bits.

摘要： A serial control apparatus includes a main controller (2) and a plurality of nodes (3) each serving as an auxiliary controller normally serially arranged on a loop-shaped signal transmission line (1). Each node (3) extracts data for the present node among from the data delivered from the main controller (2) as time elapses so as to allow the terminal units (A) associated with the present node to be properly controlled. In addition, the node inserts the output data from the terminal units (A) into a time slot corresponding to the present node and then delivers to the signal transmission line (1) the output data which in turn are transferred to the main controller (2) via other nodes on the downstream side. To assure that the data extracting circuit operates properly, two latching circuits, i.e., first and second latching circuits (311, 312 to 315) are serially arranged in a signal passage by way of which the extracted data are fed to a driver (316) for the corresponding terminal units.

摘要： A load control device for a working tool of a construction vehicle in which a signal detected by a speed detector or a traction force detector is fed back to produce a deviation signal between said signal and a desired signal. A memory unit has stored a desired value of speed or traction force for each acceleration and outputs the desired signal corresponding to an acceleration signal from an acceleration detector. The working tool is moved up or down according to the deviation signal and, through the feedback mechanism, the load applied to the working tool is automatically controlled so as to enable the construction vehicle to work at maximum work efficiency without operator's efforts.

摘要： An apparatus for carrying out serial control includes a single main controller and a plurality of node controllers for directly controlling a variety of sensors and actuators. The node controllers are serially connected to the main controller. The main controller receives a data signal row which is successively transferred through the node controllers and then indirectly and centrally controls sensor data derived from the sensors, as well as actuator control data transmitted to the actuators. Data is transmitted from the data signal row to the sensors or the actuator to be controlled and vice versa in each node controller. An error code is added to the data signal row which is to be transferred to a succeeding port under logic conditions indicating the occurrence of an error. The occurrence of an error is confirmed by inspecting an error check code which is previously added to the data signal row to check whether an error has or has not occurred between the node controllers. The error code for indicating the occurrence of error is added to the data signal row which is inputted into the relevant node controller.
