    摘要: A device for displaying images positions a luminescent material between a light source and a liquid crystal display (LCD). The light source, which comprises one or more nonpolar or semipolar III-nitride based light emitting diodes (LEDs), emits a primary light having a specified polarization direction and comprising one or more first wavelengths. This primary light emitted by the light source is a linearly polarized light that eliminates any need for a polarizer. The luminescent material, which comprises one or more phosphors, is optically pumped by the primary light and emits a secondary light having the polarization direction of the primary light, wherein the secondary light is comprised one or more second wavelengths that are different from the first wavelength. This secondary light emitted by the luminescent material is a colored light that eliminates any need for a color filter. The LCD receives the secondary light and displays one or more images in response thereto.

    摘要: A laser diode and method for fabricating same, wherein the laser diode generally comprises an InGaN compliance layer on a GaN n-type contact layer and an AlGaN/GaN n-type strained super lattice (SLS) on the compliance layer. An n-type GaN separate confinement heterostructure (SCH) is on said n-type SLS and an InGaN multiple quantum well (MQW) active region is on the n-type SCH. A GaN p-type SCH on the MQW active region, an AlGaN/GaN p-type SLS is on the p-type SCH, and a p-type GaN contact layer is on the p-type SLS. The compliance layer has an In percentage that reduces strain between the n-type contact layer and the n-type SLS compared to a laser diode without the compliance layer. Accordingly, the n-type SLS can be grown with an increased Al percentage to increase the index of refraction. This along with other features allows for reduced threshold current and voltage operation.

    摘要: A technique for growing high quality bulk hexagonal single crystals using a solvo-thermal method, and a technique for achieving the high quality and high growth rate at the same time. The crystal quality strongly depends on the growth planes, wherein a nonpolar or semipolar seed surface such as {10-10}, {10-11}, {10-1-1}, {10-12}, {10-1-2}, {11-20}, {11-22}, {11-2-2} gives a higher crystal quality as compared to a c-plane seed surface such as (0001) and (000-1). Also, the growth rate strongly depends on the growth planes, wherein a semipolar seed surface such as {10-12}, {10-1-2}, {11-22}, {11-2-2} gives a higher growth rate. High crystal quality and high growth rate are achievable at the same time by choosing the suitable growth plane. The crystal quality also depends on the seed surface roughness, wherein high crystal quality is achievable when the nonpolar or semipolar seed surface RMS roughness is below 100 nm; on the other hand, the crystal grown from the Ga-face or N-face results in poor crystal quality, even though grown from an atomically smooth surface.

    摘要: The time required for starting up drives in a storage device mounted with both hard disk drives and solid state drives is shortened. A storage controller of the storage device identifies the type (HDD/SSD) of the mounted drives before starting up the drives. The storage controller thereafter performs staggered spinup to the HDDs in several batches. After the startup of HDDs is complete, the storage controller collectively starts up the SSDs. The storage controller determines the drive startup processing based on a pre-set drive startup policy such as reduction of the peak current reduction or shortening of the startup time, and the drive type identification result.

    摘要: To detect an address error in flash memory using a different data management unit from that in a hard disk drive. In cache memory, data read/written from/to a flash memory chip is managed in units of first data lengths. A page, which is the data management unit in a flash memory chip, includes a data section of a second data length from/to which a storage controller can read/write data; and a redundant section. When writing data, the storage controller creates a protection code enabling identification of a write destination page address, divides the data in the cache memory, which is managed in units of first data lengths, into pieces so that the size of each set composed of a piece of the divided write data and its protection code will be of a second data length, and writes the respective sets in a flash memory chip in units of second data lengths.
