Abstract: A plasma-assisted deposition system for carrying out a plasma-assisted deposition method has a processing vessel defining a vacuum chamber and having an open upper end, a dielectric member covering the open upper end of the processing vessel, and a flat antenna member placed on the upper surface of the dielectric member. A coaxial waveguide has one end connected to the upper surface of the flat antenna member and the other end connected to a microwave generator. The flat antenna member is provided with many slots of a length corresponding to half the wavelength of a microwave arranged on concentric circles. For example, a circularly polarized microwave is radiated from the slots into a processing space to produce a source gas plasma. Electron temperature in the plasma in terms of mean square velocity is 3 eV or below and the electron density in the plasma is 5×1011 electrons per cubic centimeter or above. The plasma is used for depositing a fluorine-containing carbon film.

Abstract: The present invention provides an osteoporosis diagnosis aiding apparatus that utilizes a panoramic radiograph. A digitalized image of the panoramic radiograph enters a personal computer (S210). The cortical bone at the lower edge of the mandibular molar in the panoramic radiograph is specified with a mouse to make that part a target of examination (S220). This extracted image is subjected to the following image processing. (1) Subject the image to median filtering so as to reduce noises throughout that image. (2) Find a skeleton constituted by micro-structural elements (S230). (3) Extract only components parallel to the tilt of the lower edge of the mandible (S240). (4) Binarize the image using Otsu's linear discrimination method, for example (S250). The binarized lines are then classified into three groups according to size, and can be determined as a risk of osteoporosis in a case where there is more than just a single line classified in the largest line group aside from the smallest line group.

Abstract: An engine of the V-type employing camshaft drive trains each including the crankshaft, two idle gear wheels held within a gear retainer and overhead camshafts. The idle wheels are of increasing diameter from the crankshaft to the camshafts. A transmission main shaft is placed relatively close to the crankshaft because of this arrangement. A backlash adjustment mechanism is employed with the mounting provided by the gear retainer. An eccentric journal portion of an axle allows adjustment through angular adjustment of the axle. A spring mechanism may provide appropriate torque on the eccentric axle mechanism to properly control backlash. Once properly positioned, the mechanism may be locked in place for normal engine operation.
