Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

Abstract: A hybrid all-wheel-drive vehicle includes an engine, first and second motor generators, a first clutch between the second motor generator and a front wheel, a second clutch between the second motor generator and a rear wheel, and a control unit that controls, based on a vehicle traveling state, the engine, the motor generators, and the clutches.

Abstract: At each of mutually different multiple focal positions, focal adjustment parameter values are obtained from images of standard particles made of the same substance. Each focal adjustment parameter value is figured out as any one of the ratio between the density value around the center of the standard particle image and the density value around the outline, the difference therebetween, and the density value around the center. The in-focus position is adjusted on the basis of the relationship between the obtained focal adjustment parameter values and the focal positions. Moreover, on the basis of the relationship between the focal adjustment parameter values and the focal positions, the parameter values are converted into focal positions, and the focal positions and dispersion thereof are used to check the displacement of the in-focus position and the thickness of the sample liquid.

Abstract: A particle image analyzing method is adapted so that while raising image-reviewing efficiency at a cropped image level of particle components in a sample, the entire sample can be observed without significantly changing a related apparatus configuration. Prior to image reviewing of an imaging region, cropped images thereof are reviewed and, with reference to the images arranged for each kind of particle component, if the operator judges any particles to have been falsely identified, the operator uses an operating unit to modify positions of the particles to those of correct component items. An overall image of the imaging region is displayed and if any components to be added (overlooked components) appear, the kinds of these components are identified and quantitative data on each kind of component is registered. Upon completion of the registration, the concentration of the sample is recalculated and a comment is entered in a comment field.

Abstract: The particle analysis apparatus includes means that perform processes upon image processing of images (110) acquired in a measurement of the sample, simultaneously with a normal image processing for classifying target particles. The means included are: image processing means (110a) for calculating information of RGB density distributions of each whole image; abnormal state determination processing means (110c) for determining whether or not the acquired images are in an abnormal state according to tendencies of the RGB density distributions; and an abnormality judgment process means for making final determination of the existence of an abnormality by calculating an appearance frequency of abnormal images after all measurements for the one sample is completed. These means allow diagnosis of abnormalities to be conducted simultaneously with normal analysis without changing the configuration of the conventional apparatus.

Abstract: A particle image analyzing apparatus of high classifying accuracy and high efficiency in which a criterion for determining whether fine classification is required or not can be set for every facility such as hospital, or the like. A rough classification unit executes rough classification of particles and supplies results of the rough classification to a fine classification necessity determination unit. The necessity determination unit compares the results of the rough classification with reference values stored in a reference value storage unit and determines from the comparison whether every sample is normal or abnormal to thereby determine whether fine classification is required or not. The reference values stored in the storage unit can be changed in accordance with the subject of examination through an input/output control unit from a keyboard.
