Abstract: A mixed light rare earth compound which has been obtained by chemically removing medium-to-heavy rare earth elements, Nd and impurities other than rare earth elements from an ore containing rare earth elements is fired at 500 to 1100° C. to yield a mixed rare earth oxide. A cerium-based rare earth oxy-fluoride is added to the mixed rare earth oxide to obtain a mixture. The mixture is subjected to wet-pulverization, drying, firing, disintegration and classification to thereby yield a cerium-containing abrasive.

Abstract: An image processing apparatus comprises a detection unit adapted to detect a positional shift of a main object in each of the images, a coordinate converting unit adapted to convert coordinates of each of the images using a detection result of the detection unit, and a correcting unit adapted to correct image exposure by combining the images after coordinate conversion. In combination of the images, images that have fewer positional shifts are selected and combined among images that have been sensed in a number larger than the number of images with correct exposure.

Abstract: The present invention provides a low-cost light-emitting diode having little irregular color. A light-emitting diode converts light of a first light emission wavelength emitted from an LED as a primary light emission source into light of a second light emission wavelength, using one or a few kinds of phosphor materials. A thin film mainly made of a phosphor material is applied to a light extracting surface of the LED as the primary light emission source, thereby converting a wavelength and emitting light of the secondary light emission wavelength.

Abstract: A liquid residual quantity detecting method which is capable of accurately detecting the residual quantity of a liquid in an apparatus without being affected by the position of the apparatus, to thereby prevent a user from carelessly or erroneously believing that the liquid still remains. A fuel residual quantity detector detects the residual quantity of a fuel stored in a fuel storage chamber 109a of a fuel cell 108 of a camera 100. A microcomputer 205 provides control such that an operation for detecting the residual quantity of the fuel is executed only when the camera 100 is in its normal position.

Abstract: An image-pickup apparatus, a control method applied to the image-pickup apparatus, and a control program for operating a computer used for the image-pickup apparatus are provided. The image-pickup apparatus comprises an image-pickup element for picking up the images of a subject. The image-pickup element can output image signals for performing finder display and focal-point detection. The image-pickup apparatus further comprises a control device for performing first-image pickup a predetermined number of times for performing the finder display and for performing second-image pickup for performing the focal-point detection every time the first-image pickup is performed the predetermined number of times.

Abstract: A mixed light rare earth compound which has been obtained by chemically removing medium-to-heavy rare earth elements, Nd and impurities other than rare earth elements from an ore containing rare earth elements is fired at 500 to 1100° C. to yield a mixed rare earth oxide. A cerium-based rare earth fluoride is added to the mixed rare earth oxide to obtain a mixture. The mixture is subjected to wet-pulverization, drying, firing, disintegration and classification to thereby yield a cerium-containing abrasive.

Abstract: A camera has a cartridge setting chamber in which a film cartridge is set. A fork is rotatably disposed in the cartridge setting chamber and is engagable with a rotary shaft of the film cartridge to feed a film in the film cartridge. A cartridge support member is provided in the cartridge setting chamber in a position opposite to that of the fork and engagable with the rotary shaft of the film cartridge. Consequently the film cartridge is pinched between the cartridge support member and the fork.
