A liquid crystal display device with improved thermal exhaustion property, enabling a thickness reduction, includes a backlight including light sources illuminating a liquid crystal panel from a back face, and a chassis holding the backlight. The backlight includes: plural light-source units each including a combination of a LED emitting light in a direction parallel to a display surface of the panel, a wiring board mounted with the LED, and a light-guide plate having translucency for guiding the LED light toward the panel; a metal chassis supporting the light-source units; and a thermally conductive sheet tightly inserted between the metal chassis and a reverse side of the wiring board opposite to the LED-mounted face. A wiring pattern is formed on the reverse side. The metal chassis and the wiring pattern located within a predetermined distance of the LED outer periphery are connected through the thermally conductive sheet.

摘要:
When a flow of a working medium stagnates in an expander or evaporator of a Rankine cycle apparatus including a closed working medium circulation circuit, a high pressure exceeding an allowable maximum pressure level of the expander or evaporator is produced within the closed working medium circulation circuit. In such a case, the water-phase working medium is first discharged via relief valves out of the circulation circuit, so that the pressure within the circulation circuit can be lowered. Then, once vapor within the evaporator, having been lowered in temperature and pressure, flows backward within the closed working medium circulation circuit, the vapor is also discharged via the relief valves out of the circulation circuit. In this way, the pressure within the expander or evaporator can be reliably prevented from exceeding the allowable maximum pressure level.

Rankine cycle apparatus, having closed working medium circulation circuitry, includes a collection mechanism for collecting a working medium leaked or discharged out of the circulation circuitry. The working medium collected via the collection mechanism is stored in an open tank, and the thus-stored liquid-phase working medium is returned to a condenser by means of a return pump.

A vane type fluid machine includes: a casing; a rotor rotating in the casing; and a plurality of vanes supported by the rotor to slide on an inner surface of the casing. A seal portion of each vane is formed to be elastically deformable so as to slide on the inner surface of the casing while bending backward of a rotational direction of the rotor. Therefore, an improved structure of the seal portion of each vane secures good sealing performance even if machining accuracy of the inner surface of the casing is alleviated.
