摘要:
A device for purifying the exhaust gas of an engine comprises a NO.sub.X absorbent arranged in the exhaust passage. The NO.sub.X absorbent absorbs NO.sub.X therein when the air-fuel ratio of the inflowing exhaust gas is lean, and releases the absorbed NO.sub.X therefrom when the oxygen concentration in the inflowing exhaust gas becomes lower. The NO.sub.X absorbent also absorbs SO.sub.X therein when the air-fuel ratio of the inflowing exhaust gas is lean, and releases the absorbed SO.sub.X therefrom when the oxygen concentration in the inflowing exhaust gas becomes lower, with the temperature of the NO.sub.X absorbent being higher than a SO.sub.X releasing temperature. The air-fuel ratio of the exhaust gas flowing to the NO.sub.X absorbent is made rich temporarily when the temperature of the NO.sub.X absorbent is higher than SO.sub.X releasing temperature and when the flow rate of the exhaust gas flowing through the NO.sub.X absorbent is lower than a predetermined flow rate, to release the absorbed SO.sub.X from the NO.sub.X absorbent.

In an examination system including a head mounted display having image pickup devices such as CCDs provided therein and a computer, coordinates of an image to be displayed in the head mounted display can be set object- or body-centered. An image captured by the image pickup device is supplied to the computer where it will be processed in a predetermined manner for display in the head mounted display.
摘要:
A cold-cathode tube has hitherto been used as a backlight for supplying illumination to a liquid crystal television but recently, light emitting diode pieces have been used for a backlight of a large-size liquid crystal television. For the purpose of improving the emission efficiency, flip chip mounting of the light emitting diode piece is advantageous but the mounting yield is restricted by the piece size, electrode structure and wire pattern structure, facing situations having difficulties in realizing simplified mounting and reduction of costs of members. In a liquid crystal display apparatus having a liquid crystal panel, an optical system and a light source, the light source includes a light emitting element structure having positive and negative electrodes, at least one of them being plural, and wires mounted to the positive and negative electrodes through flip chip mounting by making electrical correspondence to individual regions of the positive and negative electrodes.

The present invention provides an illumination device capable of improving an efficiency of acquiring light emitted by light emitting diodes, which are provided in a light source module and used as a light source, and capable of achieving a uniform luminance distribution, and provides a liquid crystal display device using the illumination device. The illumination device includes a circuit board, red, green and blue light emitting diodes, and a lens body. Each red, green and blue light emitting diode is mounted on the circuit board and connected with a wiring pattern formed on the circuit board. The lens covers the red, green and blue light emitting diodes, and includes first portions each having two first side surfaces and second portions each having two second side surfaces. The first and second portions are alternately arranged. A distance between the first side surfaces is larger than a distance between the second side surfaces. The three red, green and blue light emitting diodes are provided in each first portion of the lens.
