Abstract: A vehicle decorative lighting device and a vehicle lamp including a lighting device can include a light guide lens formed in a substantially U-shape and a pair of LED light sources that can emit various color lights. Each of the light sources can be located at both end surfaces of the light guide lens having a U-shaped light-emitting surface. The vehicle lamp can include a lamp room between an outer lens and a housing, and can incorporate various vehicle lamps such as a headlight along with the lighting device in the lamp room. The lighting device can be located in the lamp room so as to emit various U-shaped color lights along a periphery of the outer lens. Thus, the disclosed subject matter can include providing vehicle lamps including the decorative lighting device having a harmonious favorable light distribution, for example, such that combine a headlight with a position lamp.

Abstract: According to a lighting fixture of an aspect of the present invention, only by holding the first and second strip-shaped luminous bodies on the strip-shaped luminous body holding device with the first and second strip-shaped luminous bodies being curved into a predetermined shape, the plurality of point light sources of the first strip-shaped luminous body and the plurality of point light sources of the second strip-shaped luminous body can be mounted at predetermined positions in appropriate postures (for example, such positions and postures as to illuminate a predetermined area of the front of the lighting fixture) at once. That is, each of the point light sources can be stereoscopically disposed at a predetermined position in an appropriate posture in a most expeditious manner. Also, the lighting fixture of novel visual quality capable of producing a stereoscopic effect by the real image can be provided.

Abstract: If a disk array device according to the invention initially has four disk devices, which is the smallest number of disk devices for RAID5 (3D+P), the storage region of each of the four disk devices is equally divided by four to produce partitions. Then, four partitions are selected respectively from the four disk devices and combined to form a redundancy group so that a total of four redundancy groups are formed. When another disk device is added, its storage region is also equally divided by four. Four partitions are selected from the four redundancy groups, one from each of the disk devices, and the data of the selected four partitions are copied to the four partitions of the added disk device. After the completion of the copying, the origin of copying partitions are excluded from the original redundancy groups and the corresponding four destination of copying partitions are incorporated to replace the excluded partitions.

Abstract: A disk-array controller of the present invention has data-buffers 70-75 accessible from a host device and disk units, various selectors 42-69, XOR circuits 78-79, parity check circuits 76-77. By changing the settings of these components, transmission passes are changed. The settings can be programmed more than one by set registers 340-394 and execution counters 34-39. Using time-sharing buses such as PCI buses 15, 18, each program performs parallel processing because plural programs time-share the transmission bus during the period of acquiring access permission to the bus.
