  • Patent number: 8822204
    Abstract: A culture apparatus for microscopic viewing enables effective microscopic viewing at high magnification of samples such as cells suspended in a culture solution while the samples are maintained at a uniform temperature. The apparatus is used to microscopically view a sample placed on a microscope stage, and is provided with a housing unit that houses the vessel containing a culture solution and the sample; a lid that closes the aperture on the upper surface side of the housing unit; a transparent sheet top heater provided in the portion of the lid that corresponds to the viewing area; and a temperature detecting means where a thin wire detection unit penetrates into the interiors of the housing unit and a well plate to directly measure the temperature of the culture solution. Based on the temperature information, a controller controls the temperature of the transparent sheet top heater using a feedback method.

  • Patent number: 7830598
    Abstract: A microscope stage capable of always heating the entire culture vessel even when the culture vessel is moved in two-dimensional directions, and allowing an object lens and a condenser even in a high-power microscope to approach an object of observation such as a cell until they come into focus. A heating unit (58) faces a well plate (37) on a drive base (49) even when the drive base (49) is driven to any position in two-dimensional directions. Therefore, all the cells A in the small compartments (45) of the well plate (37) are always heated. Since the microscope stage (25) is constituted such that a lower-side base (71) houses an upper-side base (73) and a fixed base (47) in recessed portions, its thickness is considerably small. Accordingly, an object lens (5) and a condenser (3) can approach close to the cells A. Therefore, it is possible for high-power object lens (5) and condenser (3) to focus on the cells A.

  • Patent number: 7718423
    Abstract: An incubator capable of observing an observed specimen in a dish 220 by a microscope while culturing the specimen, wherein light is radiated from a capacitor(C), passed through a hole 273 in a top plate 271, a hole 275a in a upper side plate 275 and a hole 277a in a lower side plate 277, and let into an objective lens (T), and the specimen put in the dish 220 is observed by the microscope, whereby the change of the specimen with elapse of time can be continuously observed or recorded on a videotape while culturing the observed specimen in the dish 220.

  • Patent number: 6951419
    Abstract: A transparent face temperature sensor 3 for measuring temperature comprises a transparent insulating substrate 7 for the sensor, a transparent electrically conductive film 9 for the sensor provided on at least either one of the surfaces of the substrate, a pair of terminals 11 connected to the film. The wires 13 are made of copper and constantan, respectively. The sensor 3 is bonded in electrical insulation conditions, to the a transparent face heater 5, via a insulating sheet 25 and a silicone resin, and hold in a housing 27. Temperature-measuring point is not one point, but an entire surface. Accordingly, the face temperature sensor 3 can detect the average temperature over the entire surface of the sensor film 9.
