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.

A communication system has a controller for transmitting data to be played back by a plurality of playback devices corresponding to a plurality of channels, and a plurality of adapters required for executing playback by the playback devices. The controller has a setting unit which sets data to be played back by the playback devices and control information required to control playback of the data in time slots of a sync transmission frame, and a transmission unit which transmits the sync transmission frame the by the setting unit to the adapters. Each adapter has a reception unit which receives the transmitted sync transmission frame, and a playback control unit which extracts data corresponding to the channel to be played back by the adapter from the sync transmission frame, and controls the playback timing of the data based on control information corresponding to the data.
摘要:
A cooling device includes a cooling panel wherein a passage is formed by bonding together a bottom heat radiation plate having a groove formed therein and a top heat radiation plate, and a circulation pump circulating refrigerant within the passage. The top heat radiation plate is provided with an outlet port through which the refrigerant flows out from the passage to the circulation pump and an inlet port through which the refrigerant flows in from the circulation pump to the passage. The circulation pump is fixed onto the top heat radiation plate of the cooling panel so that the suction port and discharge port are aligned with the outlet port and inlet port, respectively.

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.
摘要:
A diaphragm pump enabling an increase in pump efficiency by reducing the pressure loss of liquid and reduction in thickness. The flow passage in piezoelectric pump (1) includes a pressure chamber (50) formed into a flat shape in cross section and a suction side flow passage (70a) and discharge side flow passage (70b). The suction side flow passage (70a) and the discharge side flow passage (70b) are disposed at both ends of the pressure chamber (50) so that the axes thereof are aligned with each other. The check valves (20a, 20b) are respectively disposed on the suction side flow passage (70a) and the discharge side flow passage (70b), and are tilted relative to the flow direction of the liquid.
