Abstract: There is provided a high-performance image-burr correcting system of a camera, which can improve precision of a focusing process, accomplish low power consumption, and shorten a release time lag. The image-burr correcting system includes an image-burr detecting unit which can detect image burr generated upon photographing; an image-burr correcting unit which can correct the image burr based on the image-burr detection result of the image-burr detecting unit; and a focusing detecting unit which can detect the focused result. After the completion of an appropriate focusing process is detected by the focusing detecting unit, the image-burr correcting unit is driven and image-burr correction is performed in correspondence with an image burr amount detected by the image-burr detecting unit.

Abstract: A liquid fuel supply mechanism having a pump for retrieving a liquid fuel stored in an external tank and then supplying the liquid fuel into a fuel cell, and a flow passage for linking the tank to the fuel cell is disclosed. The flow passage includes a first flow passage for supplying the liquid fuel retrieved from the tank into the fuel cell, and a second flow passage for returning a waste fuel after use exhausted out of the fuel cell into the tank. The pump and the first and second flow passages and are mounted altogether on a first sheet member having a film shape to form a single body, which makes possible for the device to be miniaturized and easily handled.

Abstract: A light emitting device including a base with five planar surface sections formed at five different angles, with a plurality of receiving holes, which are spaced apart, passing through the planar surface sections; light-emitting diode chips mounted at about the center of their respective planar surface sections with a conductive paste such that they emit light in a direction perpendicular to the plane of their respective planar surface sections; terminals inserted into their respective receiving holes, with one end of each terminal being electrically connected to the corresponding LED chip; and a mold case which covers each LED chip.

Abstract: A light-emitting diode device includes a light-emitting diode, a lens cap made of synthetic resin, for covering the light-emitting surface of the light-emitting diode means, and a refractive layer formed between the light-emitting surface and the lens cap, the refractive layer having a composition, such as an air layer, with a refractive index different from the refractive index of said synthetic resin. In this arrangement the relationship between the light intensity and directional angles is shown by characteristics in which the light intensity is maximum in the center of the directional angles, and is relatively flat in the form of a sinusoid in the wide range of the directional angles. Therefore, even when the characteristics of each light-emitting diode is not verified, a predetermined light-signal transmission range is readily obtained without being affected by a scatter in the characteristics.

Abstract: A relative-angle detection apparatus which has an infrared-signal transmitting unit and an infrared-signal receiving unit. The transmitting unit includes a first light-emitting device array formed of a plurality of light-emitting devices disposed in a direction substantially coinciding with the fiducial axis for angle detection, and a second light-emitting device array formed of a plurality of light-emitting devices located to be slightly angled in the different directions with respect to the axis. The devices of the first light-emitting device array generate a continously-output first infrared signal in which an infrared signal is intermittently modulated by a first frequency and also modulated by a second frequency higher than the first frequency. The devices of the second light-emitting device array generate a second infrared signal in which an infrared signal is modulated by the first frequency and also divided into a plurality of signals so as to be output at different timings.

Abstract: A key top, of the type utilized in keyboards, is disclosed, which minimizes the lateral stress encountered by the central engaging protrusion with respect to the underlying switch. Two T-shaped reinforcing rib structures are provided on bottom surface of the top plate of the key top, with the rib structures spaced apart from the engaging protrusion, thereby providing a gap between the reinforcing ribs and the engaging protrusion, and thus dispersing lateral stress on the engaging protrusion through increased flexure of the engaging protrusion. In addition, the base of the engaging protrusion is thickened to structurally resist lateral stress.
