    摘要： An electrode is arranged in an integrally formed, seamless, self-supporting tubular ion exchanger, and a liquid supply and discharge mechanism for circulating an electrolyte is arranged in the tubular ion exchanger to construct an electrode apparatus for the dialysis. When this apparatus is used for the dialysis of an electrodeposition coating solution, leakage of the coating solution into the electrode portion and leakage of the electrolyte into a tank are prevented.

    摘要： A pattern inspection system for inspecting a pattern of a land for a through-hole formed in a printed board. In the system there are included a first illumination device for optically illuminating the printed board, a second illumination device for illuminating the printed board with light modulated at a predetermined period and an image pickup responsive to reflection light and transmission light from the printed board due to the first and second illumination devices to photoelectrically convert the printed board into a gray level image. The gray level image is converted into a bi-level image by a bi-level conversion device and then converted into an edge image by an edge detecting device. The edge image is expanded and contracted by predetermined amounts so as to obtain a through-hole image corresponding to the through-hole. A defect detecting device detects a defect of the pattern of the printed board on the basis of the through-hole image and the bi-level image from the bi-level conversion device.

    摘要： An electronic endoscope has a tip portion with a tip end. This electronic endoscope comprises an imaging element provided in the tip portion; an imaging optical system provided in the tip portion at a position closer to the tip end than the imaging element; and a plurality of light-emitting elements for emitting light, each of which is provided in the tip portion at a position closer to the tip end than the imaging element. Each of the light-emitting elements is arranged such that a part of the light-emitting element is seen so as to overlap with the imaging element when viewed from the optical axis direction of the imaging optical system. According to this arrangement, it is possible to reduce the diameter of the tip portion of the electronic endoscope. Further, when such an electronic endoscope is used as a medical endoscope, it becomes possible to relieve the pain that patients may feel.

    摘要： A capsule retriever includes a retriever and a holder. The retriever retrieves a capsule endoscope while separating the capsule endoscope from excretions, such that fluid included in the excretions can pass through the retriever. The holder holds the capsule endoscope with the retriever. The retriever is attached to the holder, so that the capsule endoscope is surrounded by the retriever and is held in the holder with the retriever, by an operation using only the holder.

    摘要： An imaging element for an electronic endoscope is disclosed. The electronic endoscope has an elongated tubular main body. At the tip end portion of the main body, there are provided an optical imaging system comprising a convex lens, a concave lens and an optical low-pass filter, a CMOS type imaging element having a CMOS sensor, and a pair of light distribution lenses. The imaging element includes the CMOS sensor, a signal processing circuit for processing a signal outputted from the CMOS sensor, and a signal control circuit for timing control for extracting a signal from the CMOS sensor. In this imaging element, the signal processing circuit and the signal control circuit are arranged along the periphery of the light-receiving surface of the CMOS sensor so that a center of the base of the sensor on the light-receiving surface is substantially aligned with a center of an effective imaging region of the image sensor.
