摘要： A master node and slave nodes which are connected in a ring-like manner transmit commands in one direction, each of the nodes transmits a state monitoring command for monitoring the operational state of the network to its immediate upstream-side node, and the operational state of the network is monitored by a response from the immediate upstream-side node with respect to the state monitoring command. A traffic monitoring unit monitors the amount of traffic in the network and determines whether or not the amount of traffic is less than a predetermined value, and a start-command transmitting unit transmits a start command for instructing the start of transmission of the state monitoring command to each of the slave nodes if it is determined that the amount of traffic is less than the predetermined value.

摘要： In each control node connected to an optical multiplex transmission path, a light receiving portion operates due to supply of a power source and receives an optical signal from another control node. A mode changing-over portion alternately changes over a multiplex communication mode and a sleep mode every prescribed period of time. A light receiving power source control portion and a first switch have alternately repeated therein a power source supply time length corresponding substantially to the multiplex communication mode during which a power source is supplied and a power source non-supply time length corresponding substantially to the sleep mode during which no power source is supplied, and thereby produces a power source supply pulse signal in which the duty ratio between the power source supply time length and the power source non-supply time length is preset and supplies this power source supply pulse signal to the light receiving portion. When the mode changing-over portion changes over the mode of the control node from the sleep mode to the multiplex communication mode and the light receiving portion has received the light signal, the mode changing-over portion causes the multiplex communication mode to be maintained during a time period in which the light signal is being received, and the light reception control portion causes the power source to continue to be supplied to the light receiving portion during a time period in which the light signal is being received.

摘要： In a normal operation mode, paths in a communication IC are controlled so that data received from a transmission line and addressed to this node is captured into a digital signal processor of the node and so that source data is sent from the node to the transmission line. In a test mode, the paths in the communication IC are controlled so that data received at a second input terminal of the communication IC is output from a first output terminal. In the test mode, comparison source data from a comparison source data unit is sent to the second input terminal via a first multiplexer. An error detection unit compares the comparison source data with output data, which is output from the first output terminal of the communication IC in response to the comparison source data, to detect errors in the communication IC.

摘要： A vibration gyroscope 10 includes a vibrator 12. The vibrator 12 has a vibration member 14 formed in a regular triangular prism shape. On side faces of the vibration member 14, piezoelectric elements 16a, 16b and 16c are formed. Two of the piezoelectric elements 16a and 16b are connected to resistors 26 and 28, respectively. Between the other feedback piezoelectric element 16c and these resistors, an oscillation circuit 30 is connected. A signal having a phase opposite to that of the signal output from the feedback piezoelectric element 16c is input to the vibration member 14 serving as a grounding terminal by a phase inverter 34. The signals output from the two piezoelectric elements 16a and 16b are input to a differential circuit 36. The differential circuit 36 is connected to a synchronous detection circuit 38 and connected to a smoothing circuit 40 and a DC amplifier 42 in series.

摘要： In a recording and reproducing apparatus, a digital luminance signal and digital color difference signals generated from an input video signal. A digital audio signal is generated from an input audio signal. The digital luminance signal, the digital color difference signals, and the digital audio signal are time-base-compressed into a compression-resultant luminance signal, compression-resultant color difference signals, and a compression-resultant audio signal, respectively. The compression-resultant luminance signal, the compression-resultant color difference signals, and the compression-resultant audio signal are multiplexed into a multiplexing-resultant signal on a time-division-multiplexing basis. The multiplexing-resultant signal is recorded on a recording medium. The multiplexing-resultant signal is reproduced from the recording medium. The original digital luminance signal, the original digital color difference signals, and the original digital audio signal are recovered from the reproduced multiplexing-resultant signal.

摘要： A color camera apparatus comprises an image pickup element having a stripe/mosaic type color filter and photo-electrically converting an arriving optical image so as to obtain at least a signal including a brightness component and a color component multiplexed with each other. And, the apparatus comprises an A/D converter for digitizing above multiplexed signal, and a brightness signal processing circuit which separates the brightness component from the multiplexed signal and carries out an aperture correction by means of a delay element having a delay amount corresponding to two horizontal scanning period. And further, the apparatus comprises a color signal processing circuit which separates the color component from the multiplexed signal so as to obtain two line-sequential color difference components through a predetermined arithmetic procedure. And, the color signal processing circuit not only carries out a circular-type noise removal processing operation by means of the delay element having the delay amount corresponding to two horizontal scanning periods, but carries out a rearrangement of said line-sequential color difference components by use of the same delay line.

摘要： An incident optical image is split by a single semi-transparent mirror into first and second optical images and directed onto first and second intersecting planes so that the images are in mirror-image relationship to each other with respect to a line of intersection between the two planes. First and second identical solid-state area imagers are located on the two planes, respectively. A pair of identical solid-state area imagers respectively include image sensors for generating charges corresponding to the optical images incident thereon. A vertically bidirectionally transferrable charge transfer device is coupled to each image sensor and a horizontally bidirectionally transferrable charge transfer device is coupled to the vertical transfer device. The vertical and horizontal charge transfer devices of both imagers are driven so that signals derived therefrom will produce identical electronic images.
