20090319237 | CAD PROGRAM, STRUCTURE DESIGN SYSTEM, AND STRUCTURE DESIGN METHOD - A computer acquires maximum lengths of a structure as measured along X-axis, Y-axis, and Z-axis directions, and acquires numbers of divisions of line segments which extend along the X-axis, Y-axis, and Z-axis directions, respectively, and have the maximum lengths, respectively. The computer then calculates a basic shape, which is the shape of a rectangular parallelepiped divided into a three-dimensional grid, on the basis of the maximum lengths and the numbers of divisions. The computer creates a basic frame of the structure from the basic shape by deleting a selected line, and adding a line between two selected grid points. The computer calculates structure data, which are three-dimensional data representing the structure, by arranging frame members, which are represented by three-dimensional frame member data, along lines between the grid points of the basic frame. The computer then outputs a drawing of the structure from the structure data. | 12-24-2009 |

20090099528 | Protector and Needle Set - A protector comprising an inner tube, a lid connected to the upper opening of the inner tube through a hinge, and an outer tube for holding the inner tube in its inner cavity part. A blood collecting needle to which a tube is connected is stored in the inner tube. The inner tube comprises an annular seat face which seats on the base end part of a hub formed integrally with the blood collecting needle when the blood collecting needle moves downward. An operation lever extending downward is installed at the side of the lid, and the end part of the operation lever is slightly projected outward. When the blood collecting needle is moved, the inner tube is pulled integrally with the tube by the annular seat face to be slid relative to the outer tube until the end part abuts on the lower end part of an operation hole. Then, the lid is closed and the blood collecting needle is stored in the inner tube. | 04-16-2009 |

20110225056 | CHECKOUT APPARATUS AND MODE SWITCHING METHOD - According to one embodiment, a checkout apparatus includes an apparatus body, a monitor, a rotation mechanism, a lock mechanism, a notification unit, and a control unit. The apparatus body can switch a mode for checkout processing between a cashier mode in which a cashier operates the apparatus and a self-service mode in which a customer operates the apparatus. The monitor is provided on the apparatus body and displays a status of the checkout processing. The rotation mechanism rotates the apparatus body. The lock mechanism locks the rotation of the rotation mechanism at least at two positions. The notification unit causes the monitor to display guidance showing a procedure for mode switching, including locking and unlocking by the lock mechanism. The control unit switches checkout processing modes in response to that the rotation of the rotation mechanism is stopped at one of the positions with the locking by the lock mechanism. | 09-15-2011 |

20150033591 | AUGER SNOW-REMOVING MACHINE - An auger snow-removing machine includes a forward rotation shaft and a reverse rotation shaft disposed on the same axis and aligned in a width direction of an auger housing within the auger housing, and a transmission disposed inside the auger housing such that the forward rotation shaft and the reverse rotation shaft are rotated concurrently in opposite directions by a driving force transmitted from the transmission. A case of the transmission is divided into a front case member and a rear case member at a position behind a reverse rotation drive shaft extending in the width direction of the auger housing. The front case member has a first gear unit assembled therein, and the rear case member has a second gear unit assembled therein. The first and second gear units are assembled together when the front and rear case members are assembled together. | 02-05-2015 |
20160032940 | CENTRIFUGAL PUMP - A centrifugal pump includes an impeller rotatably disposed in a volute case for forcing a fluid to flow along a volute internal flow channel formed in the volute case, and first to fourth flow-channel recessed portions opening to the volute internal flow channel. The first and fourth flow-channel recessed portions are formed so as to be recessed in a direction substantially orthogonal to a direction of flow of the fluid. In a self-priming operation, the fluid is introduced into the first and fourth recessed portions whereupon the prime fluid is stirred within internal spaces of the first and second flow-channel recessed portions. | 02-04-2016 |

20160113676 | THROMBUS ASPIRATION CATHETER AND METHOD OF USING THE SAME - A thrombus aspiration catheter is disclosed which can shear a thrombus and efficiently aspirate the thrombus. When the pressure of the inside of an inner tube is made negative, an outer tube is rotated around an axis relative to the inner tube, and an inner opening portion and an outer opening portion are positioned at an open position at which the inner opening portion and the outer opening portion overlap each other, a thrombus enters the inside of the inner tube through the inner opening portion and the outer opening portion. When the outer tube is further rotated up to a closed position at which the whole outer opening portion does not overlap the inner opening portion, the thrombus is sheared by an edge portion of the inner opening portion and an edge portion of the outer opening portion and into the inside of the inner tube. | 04-28-2016 |
