摘要:
A piezoelectric vibration gyroscope is composed of a main body shaped into a rectangular plate and provided with obverse and reverse surfaces functioning as major surfaces, and the first and second groups of three arms projecting from the main body in opposite directions and lying on extensions of the major surfaces. The first group of the three arms is composed of two excitation driving side arms excited in an opposite phase and a nonexcitation driving side arm inserted between the two excitation driving side arms. The second group of the three arms is composed of two vibration detecting side arms vibrating in an opposite phase and a nonvibration detecting side arm inserted between the two vibration detecting side arms. The excitation driving side arms are respectively provided with driving electrodes for exciting a tangential vibration therein. The vibration detecting side arms are respectively provided with detecting electrodes for detecting a vertical vibration. The main body prevents the tangential vibration from transitting from the excitation driving side arms to the vibration detecting side arms. The vertical vibration is generated in the excitation driving electrodes because of Coriolis force caused by an anglar velocity of the piezoelectric vibration gyroscope.

A moving-image recording/reproducing apparatus for recording/reproducing a plurality of moving images by using a plurality of moving-image I/O passages includes: a plurality of moving-image recording/reproducing devices and a switch device for selectively establishing a connection between the plurality of moving-image I/O passages and the plurality of moving-image recording/reproducing devices. The apparatus further includes a control device for controlling the switching operation of the switch device, wherein the control device performs the recording/reproducing of the moving images input/output from each of the moving-image I/O passages by allocating the moving images to each of the moving-image recording/reproducing devices in accordance with an instructed sequential order, and controls the switching operation in such a manner that a plurality of the moving-image I/O passages are not allocated concurrently to the same moving-image recording/reproducing device.

In a network system providing communication through a multi-channel transmission path with n channels, N buffers in each of plural node devices temporarily store signals for transmission through the n channels. A channel control device alters the channels through which the signals from the buffers are sent so that the signals from plural buffers cannot be sent concurrently to the same channel. A buffer control device controls the read out of signals from the buffers through the n channels selected for signal transmission synchronously with the channel alteration. A node device receiving signals from another node device includes reception devices that receive signals from the n channels, respectively.
摘要:
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.

In a network system, a loop-shaped transmission path is constituted by multiplexing a plurality of loop-shaped transmission channels. A plurality of nodes are connected to the loop-shaped transmission path. Each of the plurality of nodes can access at least two channels of the plurality of channels multiplexed in the loop-shaped transmission path. Each of plurality of nodes has a loop-shaped transmission route which is formed via a plurality of channels and which does not exceed one round of the loop-shaped transmission path.
