    摘要: A cross-point type switch includes a plurality of basic elements arranged in rows and columns so as to form a matrix arrangement of the basic elements. Each of the basic elements includes a plurality of input ports, output ports, expanded input ports and expanded output ports. A write/read part is connected to a common memory and has the function of writing data into the common memory and reading out the data from the common memory. A selector part selectively outputs either the data read out from the common memory or data from the expanded input ports to the output ports. The expanded output ports are directly connected to the input ports.

    摘要: There is provided a radar apparatus of an electronic scan type configured to transmit an electric wave and calculate an angle of a target based on a phase difference of respective reception signals, thereby detecting a target position. An antenna unit transmits and receives the electric wave and provided with two transmission antennae. A transmission unit alternately transmits an electric wave having a first beam pattern and an electric wave having a second beam pattern from the two transmission antennae. First and second reception units calculate arrival angles and reception levels of reflected waves calculated from respective reception signals which are obtained by receiving the reflected waves by the first and second beam patterns. A comparison unit compares the reception levels by combining the arrival angles of the reflected waves. A determination unit determines whether a target actually exists at the arrival angles in accordance a comparison result.

    摘要: A communication system containing a master station and a plurality of slave stations. The master station receives a request from one of the plurality of slave stations and memorizes one or more requests from one or more slave stations. The master station also sends a request sending allowance signal which addresses one of the plurality of slave stations to give an allowance to send a request for sending data, and sends a data sending allowance signal which addresses one of the plurality of slave stations to give an allowance to send data, according to a request which is memorized. Each of the slave stations detects a request sending allowance signal which addresses its own slave station, and a data sending allowance signal which addresses its own slave station. Each of the slave stations also sends a request for sending data to the master station when its own slave station detects a request sending allowance signal which addresses its own slave station. In addition, each slave station sends data to the master station when its own slave station detects a data sending allowance signal which addresses its own slave station.

    摘要: A coded transmission system wherein each bit of transmitted data having a logical value is coded depending on a coded result of a preceding bit. The coded transmission system contains a sender-side apparatus, a transmission line, and a receiver-side apparatus. In the sender-side apparatus, a resetting bit and a message are generated; a code of a bit last transmitted which is necessary to code a bit which is to be transmitted next is memorized in a first preceding code memorizing circuit; and the content of the first preceding code memorizing circuit is reset to an initial code responding to the resetting bit. A coding circuit receives the resetting bit and the message, codes each bit of the message in accordance with a predetermined coding rule and the content of the first preceding code memorizing circuit, and codes the resetting bit to a predetermined resetting code which is different from the codes used in the coding of the message. In the receiver-side apparatus, a code of a bit last received which is necessary to decode a code of a bit which is received next is memorized in a second preceding code memorizing circuit. A resetting circuit resets a content of a second preceding code memorizing circuit to a predetermined initial code when receiving the resetting code. A decoding circuit decodes the received codes corresponding to the message in accordance with the predetermined coding rule and the content of the second preceding code memorizing circuit.

    摘要: In a sequential polling type communication network system including a master station, a first channel, a second channel, and at least two slave stations, the master station includes request registration units for registering data transmission requests from slave stations during a data transmission by another slave station, and an interrupt polling unit for polling the slave station which has issued the data transmission request after completion of the data transmission or completion of a polling of a slave station, and the slave station includes a unit for responding to a polling during the data transmission, and transitting a data transmission request when data to be transmitted exists, and for responding to the interrupt polling from the master station, and transmitting the data to the master station until the data transmission is completed.
