20090050540 | Optical grain sorter - A grain images obtained by CCD line sensors are processed by binarization processing to obtain contour images of grains and images of colored portions in the grains. The images are displayed on a monitor screen of an operating panel | 02-26-2009 |
20090277304 | PROCESS FOR PRODUCTION OF FE BASED AMORPHOUS ALLOY - According to exemplary embodiments of the present invention, a process for production of an amorphous alloy can be provided at low cost by, e.g., efficiently removing magnetic-property-degrading Al and Ti when using inexpensive Fe—B or scrap as an amorphous alloy raw material. An exemplary embodiment of the process for production of an Fe-based amorphous alloy ribbon can comprise, by mass, e.g., 2 to 4% of B, 1 to 6% of Si, and a balance of Fe and unavoidable materials is provided. For example, it can be determined whether the molten alloy obtained by melting a main raw material has a Ti concentration or Al concentration of 0.005 mass % or greater: When such even occurs, iron oxide source having an iron content of 55 mass % or greater can be added thereto to reduce both Ti and Al to less than 0.005 mass % by oxidative removal. Alternatively, it is possible to determine whether the main raw material has a composition whose Ti concentration or Al concentration is 0.005 mass % or greater, and when it does, an iron oxide source having an iron content of 55 mass % or greater is precharged into a melting vessel together with the main raw material. | 11-12-2009 |
20090324315 | Amorphous ribbon take-up roll switching method and switching system - The present invention provides an amorphous ribbon take-up roll switching and method which use a take-up device provided with a plurality of take-up rolls magnetized on their surfaces so as to take up an amorphous alloy ribbon during which it is possible to simply and inexpensively switch take-up rolls stably without ribbon breaking, uneven take-up, or other trouble regardless of the amount of take-up, that is, a method of taking up amorphous ribbon having a magnetic property cast using a cooling roll by using two or more take-up rolls, which amorphous ribbon switching method characterized by, when switching the take-up rolls, bringing the amorphous ribbon into contact with the next take-up roll and cutting the amorphous ribbon being taken up in the state with the next take-up roll brought into proximity with the cooling roll or separating the next take-up roll and the cooling roll and cutting the amorphous ribbon between the take-up roll and the next take-up roll. | 12-31-2009 |
20100132907 | METHOD AND APPARATUS FOR PRODUCING AMORPHOUS RIBBON - A method and apparatus are provided for producing an amorphous ribbon by ejecting and rapidly solidifying molten alloy on a circumferential surface of a rapidly rotating cooling roll, wherein the cooling roll is polished online during amorphous ribbon production. When the circumferential surface of the cooling roll after peeling off the ribbon is polished using a polishing member, the circumferential surface of the cooling roll is polished continuously or intermittently across its lateral direction while differentiating the polishing mode in accordance with the surface properties. | 06-03-2010 |
20130271508 | DISPLAY DEVICE, DISPLAY CONTROL METHOD, AND RECORDING MEDIUM - In a portable terminal, a controller converts a tag ID as information to be transmitted to a marker used for visible light communication. The controller and a driver display the converted marker in a display. The controller and the driver adjust a display mode of the marker displayed on the display. | 10-17-2013 |
20130290490 | COMMUNICATION SYSTEM, INFORMATION TERMINAL, COMMUNICATION METHOD AND RECORDING MEDIUM - A transmission-side information terminal displays a marker whose wavelength changes with time on the basis of a tag ID acquired from a management server. A receiving-side information terminal takes an image to acquire the tag ID, and transmits storage instruction information to a distribution server, the storage instruction information including the tag ID, an area number indicating a position of the receiving-side information terminal and image data acquired by taking an image. The image distribution server stores the tag ID, the area number and the image data in the storage instruction information in association with one another. The transmission-side information terminal transmits query information including the tag ID acquired from the management server and the area number indicating its own position to the image distribution server, thereby acquiring image data associated with the tag ID and the area number from the image distribution server. | 10-31-2013 |
