    摘要: Provided is a roller screw capable of preventing rollers moving from an unloaded return path to a loaded roller rolling path from coming into collision with a scooping portion. The roller screw has: a screw shaft 1 having a spiral roller rolling surface 1a formed on an outer peripheral surface thereof; a nut 2 having a loaded roller rolling surface 2a formed in an inner peripheral surface thereof; a circulation member 3 having an unloaded return path connecting one end of the loaded roller rolling surface 2a of the nut 2 to an opposite end thereof; and a plurality of rollers 4 arranged in a loaded roller rolling path 6 and the unloaded return path. In the circulation member 3, as a scooping portion that juts toward the screw shaft 1 and provided for scooping the rollers 4 moving in the loaded roller rolling path 6 up into the unloaded return path, a pair of diagonal corresponding parts 14 is provided which are in contact with diagonal parts 4e of a rectangular side surface of each roller 4 and a width between which is gradually narrower as they are deeper in the unloaded return path in such a manner that a cross section of the unloaded return path is closer to a rectangle.

    摘要: The present invention provides a roller screw which bears loads in both directions along the axis of the screw shaft and which is also capable of preventing interference between each roller end surface and roller rolling grooves. Between roller rolling surfaces 1a, 1b of the screw shaft 1 and roller rolling surfaces 2a, 2b, respectively, of the nut 2, there are formed two or more roller rolling paths 3a, 3b, respectively. In one roller rolling path 3a, plural rollers 4a are parallel-arranged, and also in another roller rolling path 3b, plural rollers 4b are parallel-arranged. The rollers 4a arranged in the one roller rolling path 3a bear a load in one direction (1) along the axis of the screw shaft 1, while the rollers 4b arranged in the other roller rolling path 3b bear a load in the opposite direction (2) along the axis of the screw shaft 1.

    摘要: An example of a game apparatus includes a CPU. The CPU activates two outward cameras to allow a user to image, for example, a flower. The CPU filters data for search included in a database. The CPU obtains color information, shape information and a size of the imaged flower. A shape category is obtained, and with the shape category, data for search included in a database for search is further filtered. Then, by comparing the color information, the shape information, and the size of the imaged flower with the data for search to be used, a score of a degree of approximation of the color information and scores of the degree of matching of the shape information and size, etc. are obtained. Then, images of flowers as candidates are presented in the descending order of the score (similarity level).
