| 20090151691 | Tappet clearance adjusting cover coupled with secondary air valve - This invention is to provide a tappet clearance adjusting cover coupled with a secondary air valve. The tappet clearance adjusting cover is disposed on a cylinder head of an engine. The secondary air valve includes a recessed element and a cap which jointly form a receiving space receiving therein a one-way valve. The recessed element is provided with an inlet pipe interposed between the cap and the tappet clearance adjusting cover. By disposing the secondary air valve on the tappet clearance adjusting cover and arranging the inlet pipe between the cap and the tappet clearance adjusting cover, with the one-way valve received in the receiving space of the secondary air valve, heat dissipation can be improved while the one-way valve is protected against premature deterioration and carbon deposition caused by a high-temperature exhaust gas from the cylinder head. Thus, reliability as well as a service life of the one-way valve is effectively increased. | 06-18-2009 |

The frame includes a plurality of sidewalls connected with each other which cooperatively define a receiving space. The backlight module and the display panel are received in the receiving space. The display panel is fixed to the frame and placed on top of the backlight module. | 02-16-2012 |
| 20120039087 | DISPLAY DEVICE - A display device includes a top housing, a bottom housing engaged with the top housing, and a display module. The top housing and the bottom housing cooperatively define a receiving space for the display module. The display module includes a light source and a light guide plate. The light guide plate includes a light input surface adjacent to the light source, a light output surface, and a bottom surface opposite to the light output surface. The light input surface connects the light output surface to the bottom surface. The inner surface of the bottom housing includes a reflective portion opposite to the bottom surface of the light guide plate, such that the reflective portion reflects the light emitting from the bottom surface to the light output surface. | 02-16-2012 |
