    摘要： A piston-type compressor has a plurality of cylinder bores, each of which receives a piston assembly. Each piston assembly reciprocates between a top dead center and a bottom dead center in each cylinder bores. Each piston assembly includes a piston and a piston ring. A first groove is formed on an outer peripheral surface and at about a first end of the piston. The piston ring, which has a truncated cone-shape is inserted into the first groove, such that a wider edge of the piston ring opens toward a piston skirt portion of the piston and a narrower edge of the piston ring abuts a bottom surface of the first groove. A second groove is formed on an interior wall of the cylinder bore, and extends along an axial line between a crank-chamber-side end of the cylinder bore and about an end of bottom dead center position.

    摘要： A cross-sectional area calculation section calculates a cross-sectional area of a subject as physical quantity with respect to a size of the subject, and an NEC calculation section calculates a noise equivalent count NEC as physical quantity for evaluating an image. The C-NEC calculation section calculates a noise equivalent count per unit area C-NEC as physical quantity for evaluating an image as per size of the subject in accordance with the cross-sectional area of the subject calculated in the cross-sectional area calculation section and the noise equivalent count NEC calculated in the NEC calculation section. Accordingly, the noise equivalent count per unit area C-NEC is calculated as noted above, whereby an index may be determined that is independent of the cross-sectional area of the subject in evaluating the image.

    摘要： An optical apparatus minimizes autofluorescence and stray light as well as leakage of excitation light and efficiently utilizes illuminating light from a fluorescence illumination optical system to allow observation of a bright fluorescence image. An observation apparatus has an objective, an observation optical system unit including a variable magnification optical system, and an imaging optical system unit including an imaging lens and an eyepiece. A fluorescence illumination apparatus, which is provided separately, is removably attached to the observation apparatus. The fluorescence illumination apparatus has a light source, a collector lens unit, and a reflecting member placed between the objective and the observation optical system unit at a position displaced from the optical axis of the objective to make light from the light source incident on the objective. An excitation filter is provided between the light source and the reflecting member. An optical member for selectively transmitting fluorescent light emitted from a sample is placed between the objective and the observation optical system unit.
