Abstract: A generator section and a pair of drive sections are disposed along the lengthwise of a piezoelectric ceramic plate. The one pair of drive sections are disposed at both ends or at one end of the plate and have a pair of electrodes for each. The piezoelectric ceramic plate in the drive sections are polarized oppositely in direction and connected to a pair of external terminals. The generator section has two pairs of opposed electrodes which are polarized oppositely from the center along the lengthwise of the plate. The two pairs of opposed electrodes are respectively short-circuited and connected to external terminals. A voltage can be taken out from between the external terminals of the generator section at the vibration nodes when the piezoelectric ceramic plate in the drive section is vibrated by applying an AC voltage to between the input terminals on the drive section side at the resonance frequency of the fourth-order mode longitudinal vibration in lengthwise.

Abstract: In a first node device of a network system wherein plural node devices are connected through N numbered channels for signal transmission, N numbered buffers temporarily store signals to be transmitted and transmission units send the signals from each buffer through the N numbered channels. A channel altering control unit controls the transmission units to alter the channels through which the buffer signals can be sent according to a predetermined pattern that prevents signals from plural buffers from being sent to the same channel at the same time and a buffer controller operating synchronously with the channel alteration, controls the buffers to read out signals through desired channels. A second node device receives the signals from the first node device through the N numbered channels.

Abstract: A moving image network system which has high response to a moving image transmission request and prevents interruption of a moving image signal. Upon transmitting moving image data from terminal 1 to terminal 2, controller 20 adds a transmitter terminal address, priority and a coding type of the moving image data to transmission load information received by transmission load information receiver 17, and outputs the data to transmission load information transmitter 16. The controller 20 encodes/decodes moving image data in accordance with transmission load information of the moving image data and adjusts transmission data amount corresponding to transmission load of a transmission path.

Abstract: This application provides a network system that can obviate the need for arbitration control, and can realize bidirectional communications and loopback communications. In the network system, a first channel to be transmitted in the first direction, a second channel to be transmitted in the second direction, and third and fourth channels distinguished from the above-mentioned channels are used, and the packet to be looped back is transmitted using either the third or fourth channel. The transmission direction of the third or fourth channel is determined or changed in the self node device or in another node device, thus realizing loopback communications. In order to output a packet temporarily stored in a buffer using a desired channel, a device for changing the channel to which the buffer is connected is used, and the packet is read out from the buffer in correspondence with the changed channel to be connected.
