  • Patent number: 7788108
    Abstract: A period required for a time-consuming cross-contamination test is cut down or omitted, and a burden imposed on the customer by the costs of samples, reagents, etc. used in the test are reduced. A data failure caused by cross-contamination can be efficiently prevented. A maintenance service office establishes a connection via a communication line between a computer installed in the maintenance service office for maintenance of automatic analyzers and a customer's automatic analyzer or a personal computer placed in a customer's facility. The maintenance service office receives information regarding cross-contamination from reagent manufacturers and other customers (such as clinical examination rooms or centers) and validates it. The validated information is transmitted from the maintenance service office to the customer's automatic analyzer or personal computer via the communication line.

  • Publication number: 20100165181
    Abstract: When the mode is set to a strobe consecutive shooting mode, an imaging apparatus sets the mode to a pixel addition drive mode for reading out image data using pixel addition drive, performs metering operation using preliminary flashing and calculates an appropriate amount of flashing on the basis of the metering operation. Next, the imaging apparatus judges whether or not it is possible to flash three times consecutively with the calculated amount of flashing. If it is judged that it is not possible to flash three times consecutively with the calculated amount of flashing, the imaging apparatus limits the amount of flashing to the largest amount of flashing within the range of amounts of flashing with which flashing of strobe light three times consecutively is possible, and performs strobe consecutive shooting with the limited amount of flashing.

  • Patent number: 7655950
    Abstract: The present invention provides a manufacturing method of a high performance active matrix substrate at a high throughput with a less expensive apparatus, and an image display device using the active matrix substrate. On a stage moving in the short axis direction X and long axis direction Y on a rail, a glass substrate is carried, which has an amorphous silicon semiconductor film formed. Polycrystallized and large grain silicon film may be obtained by intensity modulating the pulsed laser beam in a line beam shape by means of a phase shift mask with a periodicity in the long axis direction Y of the laser beam, moving the laser beam randomly in the modulation direction of the amorphous silicon semiconductor film formed on the glass substrate to expose to crystallize the film. The image display device may incorporate an active matrix substrate having active elements such as thin film transistors formed by this silicon film.
