摘要:
A method of preparing a barium fluorohalide phosphor including a mixing step in which phosphor materials are mixed, a firing step in which a resulting mixture of phosphor materials is fired, an annealing step, and a cooling step in which the mixture of phosphor materials is cooled to the ordinary temperature. In the firing step, after the mixture of phosphor materials has been fired at a constant temperature, an atmosphere at the time of the firing is removed while the constant temperature is maintained, and is replaced with an atmosphere different from the atmosphere at the time of the firing, and thereafter, annealing is carried out. In the cooling step, the atmosphere at the time of the firing is removed and replaced with a first different atmosphere, and then first cooling is carried out. Further, the first atmosphere is removed and replaced with a second atmosphere, and then second cooling is carried out. Alternatively, in the cooling step, the atmosphere at the time of the firing is removed and replaced with vacuum or a neutral gas atmosphere, and then cooling is carried out.

The invention provides an electrostatic capacity type touch sensor that is not influenced by a parasitic capacitor formed between a sensor line connected to a touch sensor pad and other signal line and provides a stable sensor output. A sensor line connected to a touch sensor pad is connected to a non-inverting input terminal (+) of a charge amplifier. An LED is disposed in the touch sensor pad, and the cathode of the LED is connected to an LED signal line. Since the LED signal line is disposed adjacent to the sensor line, a parasitic capacitor is formed between the LED signal line and the sensor line. In order to keep the capacitance of this parasitic capacitor constant, a pull-up resistor is connected to the LED signal line. The LED signal line is biased to a power supply potential Vdd by the pull-up resistor.

A microscope includes a microscope main body, a revolving nosepiece rotatably mounted on the microscope main body and equipped with plural objective lenses, and focusing handles that adjust focal points of the objective lenses. The microscope further includes operation knobs mounted in a vicinity of the focusing handles and configured to move by a predetermined amount in a predetermined direction, and an operating-force transmitting mechanism provided between the operation knobs and the revolving nosepiece and configured to transmit, when the operation knobs move, operating force to the revolving nosepiece to cause the movable member to move so that the objective lenses can be switched from one to the other through a single moving operation of the operation knobs by the predetermined amount.

An inverted microscope includes a lens holding mechanism which holds an objective lens arranged under a sample and used to form an observation image of the sample; a focusing mechanism which holds the lens holding mechanism on its upper part and moves the objective lens up and down together with the lens holding mechanism; and a microscope main body which serves as a casing including the focusing mechanism therein, and includes an opening allowing an attachment of the focusing mechanism and the lens holding mechanism in its upper wall surface. A size of the lens holding mechanism in a horizontal plane is larger than a size of an image projected onto the horizontal plane of the opening.

The problem to be solved by the present invention is to provide a microscope that prevents a dew condensation on an objective lens and allows obtaining a good microscopic image, and a method of preventing a dew condensation on an objective lens.A microscope includes an objective lens having a heater 22 in a cell incubator 3 having a high humidity space. The high humidity space is maintained at 90% to 100% of relative humidity and controlled to be at a predetermined gas temperature. A cultured cell 12 in the cell incubator 3 is observed via the objective lens 1, and the heater 22 is controlled to make the temperature of the objective lens 1 higher than the gas temperature of the high humidity space.

An observation apparatus includes an incident-light illumination optical system, a transmitting illumination optical system, an imaging unit, an input device, a storage unit, an imaging controller, a microscope controller, an imaging information management unit. The imaging information management unit compares an area position, of an imaging area of the imaging unit, indicated by position information input from the input device with an area position stored in the storage unit to determine whether the area position indicated by the position information is stored in the storage unit. When the area position is not stored in the storage unit, the imaging controller controls the imaging unit to image the specimen and to generate an observation image, and stores the observation image in the storage unit. The microscope controller controls one of the optical systems to illuminate the specimen only during an imaging period, when the imaging unit images the specimen.
