Abstract
A process control system and method is provided. The system comprises a process control device for issuing a requirement command with an added address and/or group ID and a plurality of multiplexed output devices which receive the requirement command and execute a process on the basis thereof. The addresses have a same part or the group ID that are set the same for the devices. Each device compares the same part (or the group ID) with a part of a further address (or group ID) added to the received requirement command. If the same part is equal to the part of the further address, the requirement command is identified. The address is then compared with the further address based on a result of the identification. If the address is equal to the further address added to the requirement command, the process based on the requirement command is executed.

Abstract
A control apparatus has a communication control unit communicably connected to a first communication channel, at least a portion of which constitutes a serial transfer operation. The communication control unit transmits/receives information with respect to an equipment under control via a second communication channel, a portion of which constitutes a parallel transfer operation. The apparatus comprises: a communication channel diagnostic unit for diagnosing an abnormal event such as an open and stuck-at of a parallel transfer portion of the second communication channel under such a condition that a data transfer operation in the second communication channel is interrupted. A signal for instructing an initiation of a diagnosis via the first communication channel is transmitted to the communication channel diagnostic unit.

Abstract
In a control apparatus which transmits/receives data from a central processing unit via a serial transfer channel to a communication control unit, and groups/distributes data of input/output units from the communication control unit via a parallel transfer channel, the control apparatus initiates a diagnosing unit of the parallel transfer channel in response to an instruction issued from the central processing unit, and diagnosis the input/output units subsequent to the diagnosis of the transmission channel. Data input/output timing of the input/output unit is also instructed from the central processing unit, so that the central processing unit can suppress lowering of response speeds caused by the diagnoses, and can maintain the periodicity of the data input/output.

- 1 - Abstract: A recording tape cartridge comprises a cartridge case, a lid member having a front plate mounted on the case to be rotatable between a closed position and an open position. An opening in the bottom portion of the front plate receives a standard pin of a recording device. An abutting device projects from the front of the bottom wall of the case to protrude into the opening of the lid member up to a position substantially corresponding to the middle of the thickness of the front plate when the lid member is in its closed position. This arrangement effectively prevents dust or other dirt entering the case and ensures that any scratches on the front surface of the case are inconspicuous.
- 1 - Abstract: A two-level alternate mark inversion signal trans- mission system converts binary pulses of "1" and "0" into a pulse signal in which one has its polarity inverted at a period T and the other at a period ?. The converted signal is then transmitted. In order to facilitate an automatic gain control and the extraction of a timing signal in the receiver, even when the zero binary pulses have successively arisen, on a transmitting side, the alternate mark inversion signal is converted in the transmitter into a specified code (zero substitution), while in the receiver, the received signal is subjected to duobinary shaping whereby the zero substitution part of the signal is detected for removal by utilizing the rules of the zero substitution and the alternate mark inversion signal.

- 1 - Abstract An information processor comprises a plurality of instruction execution units and a circuit that distributes the decoded information of a succeeding instruction to one of the instruction execution units on the basis of sequentially decoded information of succeeding instructions and the decoded information of preceding instructions under the control of the instruction execution units. Specifically, the distribution circuit distributes the decoded information of the succeeding instruction conflicting with the preceding instruction to the instruction execution unit that is controlling the preceding instruction. The respective instruction execution units can thus execute the instructions independently of one another while guaranteeing a correctly operated result. The result is enhancement of the processing capability.
