| 20110025251 | MOTOR DRIVING DEVICE - A motor-driving device comprising: a switching element to control a current passed through a first coil of a stepping motor including the first and a second coils electromagnetically coupled; a rectifier element to be energized in a ground-side-to-second-coil direction; a coil-current-detection unit to detect a current passed through the first coil; a regeneration-current-detection unit to detect a current passed through the rectifier element; a control unit to turn off the switching element when the current passed through the first coil reaches a predetermined-set current based on a detection result of the coil-current-detection unit; and a negative-current-detection unit to detect whether a negative current greater in absolute value than a predetermined-set value is passed through the rectifier element based on a detection result of the regeneration-current-detection unit, the control unit keeping the switching element off when the negative current is not passed, based on a detection result of the negative-current-detection unit. | 02-03-2011 |

| 20080254959 | Universal head and machine tool with universal head - A universal head changes the orientation of a tool freely and machines a workpiece with the tool in the changed orientation. The universal head comprises a universal head body, for swiveling movement, including a swinging unit and an attachment detachably mounted on the swinging unit with a rotating tool removably mounted on the attachment. The universal head has, and simultaneously offers, the advantages of both a universal head, which allows the tool to change its orientation freely for machining a workpiece, and an attachment which allows the tool to be brought closely to the workpiece for machining the workpiece. The universal head does not require a process of installing itself on and removing itself from a universal head support. | 10-16-2008 |

| 20080242527 | GLASS COMPOSITION TO BE USED FOR MANUFACTURING INORGANIC FIBER, METHOD OF MANUFACTURING THE SAME AND MOLDED PRODUCT OF INORGANIC FIBER - A glass composition improves the bio-solubility (solubility to physiological salt water), and is suitable for manufacturing inorganic fiber and a molded product of such inorganic fiber. The glass composition to be used for manufacturing inorganic fiber is characterized by containing SiO | 10-02-2008 |
| 20090064718 | Method and apparatus for producing glass fiber - It is therefore an object of the present invention to provide a method and an apparatus for continuously producing high quality glass fiber that shows excellent characteristics required to various glass fiber products in terms of fiber length, fiber quality and fiber distribution and, at the same time, that allows to prolong the service life of the rotating body, that improve the productivity, and that suppress any increase in the producing cost. An axial and/or circumferential rows of orificeless sections are provided in a peripheral wall of a hollow rotating body. Also, a gas flow is provided around a flame flow, and a compressed gas flow are also provided. | 03-12-2009 |
