  • Publication number: 20090262500
    Abstract: There are provided a cooling device and a heat sink that can effectively radiate heat generated by a heat source while reducing the volume of discharged gas to avoid noise, and an electronic apparatus in which the cooling device and the heat sink are mounted. A heat sink 3 includes cutouts 24a and 24b through which air serving as gas can be taken in from the outside and which are provided on a side where air discharged from first and second nozzles 6 and 7 serving as openings of a jet generating mechanism 2 is received. Therefore, the pressure near the cutouts is decreased by air flow discharged from the first and second nozzles 6 and 7, and outside air is taken in through the cutouts 24a and 24b. Consequently, more gas than gas discharged from the first and second nozzles 6 and 7 is discharged from an outlet of the heat sink. This can minimize the volume of jetted gas to avoid noise, and effectively radiate heat generated by a heat source.

  • Patent number: 7199772
    Abstract: An optical switching element having a simple configuration and high response and capable of performing gradation display by area gradation is provided. In a state where a light extracting portion is in contact with an upper substrate, light enters the light extracting portion from the upper substrate, emits from the back face of the light extracting portion, is passed through a lower substrate, and becomes transmission light. In a state where the light extracting portion is attracted by the lower substrate side, the incident light is totally reflected by a total reflection face, and total reflection light emits from a V-shaped groove. The incident light can be switched in two directions and obtained as the transmission light and the total reflection light.
