摘要:
The present invention provides a cooling apparatus which is easy to build and to fix it to electronic devices, superior in thermal conduction and heat dissipation, and possible to make thin the total configuration of the apparatus. The liquid cooling unit 9 and the air cooling unit 12 are formed in a unit. A heat absorption surface 19 of the liquid cooling unit 9 is contacted or bonded to the heat generation component such as the CPU and the heat generator, which have the largest power consumption and also locally generate heat within a small area in the box 2. In the liquid cooling unit 9, a liquid cooling pump 14 composed of an electromagnetic pump is arranged for circulating the coolant in the flow path 10. The heat generated by the heat generation components such as CPU 6, heat generator 7, and the like is thermally diffused with heat conduction into the whole liquid cooling unit 9 by circulating the coolant with the liquid cooling pump 14.

In a network system for effecting signal transmission by plural channels, there are provided plural channel alteration units each of which is adapted to receive signals through plural channels and to output each of the signals entered by said plural channels in any of plural channels. Transmission control is executed in such a manner that mutually proximate plural signals, which have to be outputted by a designated same channel among the plural channels from a first one of the plural channel alteration units, are entered through respectively different channels into the first channel alteration unit. As the first channel alteration unit receives the plural signals by different channels, there can be resolved the drawback of a long waiting time for the output of the signals by a desired channel, encountered in case the signals are entered by a signal channel.

A switching device include a buffer for temporarily storing a signal sent by a corresponding input terminal; variable channel transmission units, one of which is provided for each input terminal, for outputting a received signal with one of N different channels; fixed channel reception units, one of which is provided for each output terminal, for receiving the signal carried with a given channel and for outputting a signal with the given channel to a corresponding output terminal, with the given channel not overlapping any other; a variable channel control unit for synchronously altering, in consonance with predetermined patterns, channels with which the variable channel transmission unit outputs a signal, so that two or more variable channel transmission units do not simultaneously output signals with the same channel; and a buffer control unit for synchronously reading from the buffer a signal that is to be output, while altering the channel with which the variable channel transmission unit transmits a signal. Provided for the buffer is a function for sorting signals for output terminals at which the signals are to be output, and weighting of predetermined patterns is performed with a time at which one variable channel transmission unit outputs signals with the individual channels during one pattern cycle.

A node device for performing packet communication using a transmission line composed of a plurality of channels is connectable to a network having a plurality of node devices, each of the plurality of node devices connecting the transmission line to a sub-transmission line. The node device a has packet processor for processing a packet, first, second, and third devices for outputting a packet, a memory device and a transmitter. The first device corresponds to each of the plurality of channels and outputs a packet input on a predetermined one of the plurality of channels to a side of the sub-transmission line or a side of the transmission line. The second device corresponds to each of the plurality of channels and outputs a packet transmitted through the sub-transmission line to the transmission line side or the packet processor side. The third device outputs a packet supplied thereto from the packet processor to the sub-transmission line side. The memory device corresponds to each of first and second devices, and temporarily stores a packet output from each of the first and second devices. The transmitter transmits outputs from the memory device in channels different from each other.

A network system for effecting signal transmission by connecting node devices with at least plural N channels is disclosed. It includes a first node device constituting at least a node device and having: N fixed-channel reception units for receiving the N channels; N buffers for temporarily storing signals received by the N fixed-channel reception units, wherein a buffer of the N buffers divides the received signals into first signals with designation of a channel for transmission and second signals without designation of a channel for transmission and further divides the first signals in respective designate channels; transmission units for transmitting the first and second signals released from the N buffers in the N channels; an end detection unit for detecting an end of reading of the first and second signals to be transmitted by channels currently capable of transmission; a channel variation control unit for controlling the transmission unit to vary the channels capable of transmitting released signals from the N buffers, in response to a detection of the end of reading by the end detection unit such that the released signals from two or more of the N buffers are not simultaneously supplied to a same channel; and a buffer control unit for controlling the N buffers, in synchronization with a variation of the channels capable of transmitting the released signals from the N buffers, to read the first and second signals be based on the variation of the channels.
摘要:
When dynamic image signals from a plurality of dynamic image signal sources are simultaneously received by a plurality of receivers, a dynamic image signal to be transmitted is transmitted while being divided into one or a plurality of partial dynamic image signals. In each of the plurality of dynamic image output devices, a desired number of received partial dynamic image signals are displayed in a desired size, thereby preventing a decrease in transmission efficiency caused by transmission of a large amount of dynamic image information exceeding the capacity of a transmission path.

An optical modulation device includes: a ferroelectric liquid crystal disposed between a pair of substrates; provision for applying an alternating voltage sufficient to render the ferroelectric liquid crystal turbid; and provision for superposing a DC voltage on the alternating voltage. A portion of the ferroelectric liquid crystal rendered turbid through the application of an alternating voltage is selectively caused to have an increased transmittance when superposed with a DC voltage.
