摘要:
A reliable scroll-type compressor is provided which, even when the compressor is rotated in the reverse direction by the erroneous connection of the power source terminals for example, is prevented from establishing a vacuum state within the compression chamber and no damages occur in the addendum of the stationary scroll and the orbiting scroll. The compressor includes a gear pump which includes a pump case and a pump port. The arrangement of the present invention is such that the pump case alone rotates by 180 degrees upon the reverse rotation of the motor, so that lubricating oil which is at the bottom of a hermetic vessel can be ensured to be supplied by the gear pump to each sliding portion of the compressor.

A reliable scroll-type compressor is provided which, even when the compressor is rotated in the reverse direction by the erroneous connection of the power source terminals for example, it is prevented from establishing a vacuum state within the compression chamber and no damages occur in the addendum of the stationary scroll and the orbiting scroll. Since the sliding surface of the slide is arranged to have an angle so that the slider is moved therealong in the direction in which the revolution radius of the orbiting scroll of the compressor is decreased, a clearance is generated between the stationary scroll and the orbiting scroll upon the reverse rotation.

In a liquid crystal display device, a first substrate adjacent to a liquid crystal display panel is subjected to rubbing in a first direction that is the same as a polarization axis direction of light emitted from the liquid crystal display panel, and a second substrate that interposes a liquid crystal layer with the first substrate is subjected to rubbing in a second direction at a right angle with the first direction. The second direction is made the same as the polarization axis direction of polarized sunglasses to allow visual recognition of the image using the polarized sunglasses. Electrode patterns formed by alternately providing narrow and wide electrodes are arranged on the upper and lower substrates in a direction at a right angle with each other so that the rubbing directions on the upper and lower substrates form a right angle to ensure stable 3D display.

An image is displayed by modulating TM-polarized light between the polarizer 2 and the wire grid polarizer 18 through the variation of the optical characteristic of the liquid crystal layer 12 interposed between the transparent plate 4 and the transparent plate 26. Degradation of contrast in the bright ambience is avoided by providing an absorption layer for absorbing TE-polarized light on that surface of the wire grid polarizer 18 which faces the liquid crystal layer 12.

An illuminating device includes: a light source; a light guide plate which converts light emitted from the light source into a surface light ray and emits the surface light ray through a front surface of the light guide plate; and an optical sheet which changes a propagation direction of the surface light ray emitted from the light guide plate. The light source is arranged in end surface different from the front surface in the light guide plate. A polarization state converting structure to convert a polarization state of the light propagating through the light guide plate is provided in a surface opposing the front surface in the light guide plate. The polarization state converting structure contains an inclination plane having a ridge line in a direction different from a direction in parallel to the longitudinal direction of the end surface.

A light-emitting device which is manufactured by a simple manufacturing method and which efficiently extracts light emitted from an emissive layer outward to improve the light extraction efficiency. The light-emitting device comprises a first electrode, a second electrode and an emissive layer disposed between them and extracts a part of light emitted from the emissive layer as radiated light. In this light-emitting device, the first electrode, the nano-structure layer for extracting the radiated light, and a gap having a refractive index lower than an average refractive index of the emissive layer and a nano-structure layer, are arranged in that order in a direction in which the radiated light is extracted.
