摘要： A light emitting device is provided in a dental handpiece device for illuminating an area in the vicinity of a dental care tool at a tip of the dental handpiece device. The light emitting device includes a light emitting section including a light emitting diode element and an electrode, and an electric power control section for controlling electric power to be supplied to the light emitting diode element via the electrode. The electric power control section includes an electric current restriction element for restricting an amount of electric current to be supplied to the light emitting diode element, and a reverse voltage prevention element for preventing a reverse voltage from being applied to the light emitting diode element.

摘要： An optical memory device is specifically so designed that, when an reference beam is applied thereto, the entire information area of its core layer can receive the reference beam all at a time to surely reconstruct a correct image. The optical memory device includes a core layer and a cladding layer laminated on both surfaces of the core layer. In this device, at least one interface between the core layer and the cladding layer has a concave and convex pattern for information to form a waveguide and a reference beam is introduced into the core layer through the end of the waveguide for reconstructing the information recorded in the concave and convex pattern for information, and the degree of bending, &Dgr;t, of the core layer at the end of the information area in which the concave and convex pattern for information is formed satisfies the condition represented by &Dgr;t≦d−t, in which d indicates the vertical width of the reference beam, and t indicates the thickness of the core layer in the information area.

摘要： An image sensor uses an image reading element formed by integrating pixels for converting image information to an electric signal. In each of the pixels, a common electrode common to all the pixels and an individual electrode corresponding to each of the pixels are disposed through at least an organic photoconductive layer. A crosstalk capacitance of each of the pixels is equal to or smaller than 35% of a sum of an electric capacitance between individual electrodes and an output capacitance of the individual electrode. A blocking layer may be disposed between the common and individual electrodes. Each of the pixels may be constructed such that the individual electrode is arranged on a supporting body, and a blocking layer and the photoconductive layer are formed on the individual electrode, and the common electrode is arranged on the blocking and photoconductive layers. Otherwise, each of the pixels may be constructed such that the common electrode is arranged on a supporting body, and a blocking layer and the photoconductive layer are formed on the common electrode, and the individual electrode is arranged on the blocking and photoconductive layers.
