摘要:
A light-emitting diode includes a substrate, a compound semiconductor layer including a p-n junction-type light-emitting part formed on the substrate, an electric conductor disposed on the compound semiconductor layer and formed of an electrically conductive material optically transparent to the light emitted from the light-emitting part and a high resistance layer possessing higher resistance than the electric conductor and provided in the middle between the compound semiconductor layer and the electric conductor. In the configuration of a light-emitting diode lamp, the electric conductor and the electrode disposed on the semiconductor layer on the side opposite to the electric conductor across the light-emitting layer are made to assume an equal electric potential by means of wire bonding. The light-emitting diode abounds in luminance and excels in electrostatic breakdown voltage.

摘要:
A computer-readable medium storing a data management program makes a computer manage data redundantly stored in storage devices having storage areas split into slices for data management. The data management program realizes the following functions in the computer. A first function receives irregularity information indicating that each of one or more of the storage devices may be possibly faulty, and stores the irregularity information in a storage; and a second function determines, by reference to the irregularity information, whether or not a first storage device containing a slice to be accessed is possibly faulty, on receipt of access information indicating occurrence of a request to access the slice. When yes is determined, the second function instructs an external device to recover data stored in the slice, where the external device controls a second storage device storing redundant data identical to the data stored in the slice.

A plurality of pixel groups X(n) each comprising a plurality of pixels are set, and switched capacitor amplification parts are provided in correspondence to the pixel groups, respectively. Each of the switched capacitor amplification parts has a charge detection node to which output terminals of the transfer transistors of a corresponding pixel group X(n) are connected in common, an amplification part, a reset transistor, a first capacitance element, and a select transistor. A load part common to the switched capacitor amplification parts is provided. The load part is combined with the amplification parts of the switched capacitor amplification parts to constitute inverting amplifiers, respectively. By means of the above constitution, it is capable of obtaining a noise-reduced, high-quality image and which allows transistor count per pixel to be cut, thus allowing the pixel size to be reduced.

A third holding barrel is set to a stationary work holder, and a lens frame holding an eighth lens group is set to a movable work holder. The movable work holder is moved to insert the lens frame inside the third holding barrel. In this state, a chart image through the eighth lens group is projected on a screen. While checking the center and clarity of the projected image on the screen, position of the eighth lens group is adjusted. After the position adjustment, an adhesive is injected through openings of the third holding barrel by an injector, thereby fixing the lens frame to the third holding barrel.
