摘要:
X-ray camera of the present invention comprises an X-ray irradiation unit, an X-ray image sensor, a controller having a correction factor setting unit, a correction factor storage unit and a correctional operation unit, and a display unit. The X-ray image sensor in the above configuration comprises a sensor such as CCD, TFT, and the like having a scintillator on a surface thereof, and a substrate having the sensor mounted thereon. The correction factor setting unit obtains a value La/Ln by dividing a predetermined brightness reference value La set beforehand by a brightness value Ln of an arbitrary pixel “n”, and sets the obtained value as a correction factor for each pixel. The correction factor storage unit stores the correction factor set by the correction factor setting unit. The correctional operation unit obtains the correction factor from the correction factor storage unit, and performs a corrective operation.

A method is described for producing an L-amino acid or a nucleic acid by culturing a microorganism having an ability to produce the L-amino acid or nucleic acid in a liquid medium in a fermentation tank containing a stirring impeller, and optionally adding seed crystals to the medium as required to produce and accumulate crystals of the L-amino acid or nucleic acid in the medium, and collecting crystals of the L-amino acid or nucleic acid from the culture. The power density of the stirring impeller is controlled to be 2.4 kW/m3 or lower after either precipitation of the crystals or addition of the seed crystals.

There is provided a compressor capable of feeding lubricating oil to a blade of a rotary type compression mechanism even if the oil level in an oil reservoir lowers. The compressor 1 includes a low stage-side rotary type compression mechanism 3 having a rotor 34, and a blade 38 reciprocating with the rotation of the rotor 34 while the tip end thereof is in contact with the rotor 34; a high stage-side scroll type compression mechanism 4 for sucking and compressing refrigerant gas compressed by the low stage-side rotary type compression mechanism 3; a positive displacement lubrication pump 60 for feeding lubricating oil 27 to the high stage-side scroll type compression mechanism 4; and an oil feeding path for feeding the lubricating oil 27, which is fed to the high stage-side scroll type compression mechanism 4, toward the blade 38 of the low stage-side rotary type compression mechanism 3.

An electric vacuum cleaner comprises a vertical type cleaner body provided with a dust collection chamber a handle protrusively provided on an upper portion of the cleaner body, a suction nozzle provided on an lower portion of the cleaner body in such a manner as to communicate with the dust collection chamber being rotatable back and forth with respect to the cleaner body, and being contactable with a surface to be cleaned, an electric fan provided in the suction nozzle, and a rotary brush which is rotated by the electric fan and is built in the suction nozzle. A clutch mechanism which transmits and interrupts power to the rotary brush is provided between the rotary brush and the electric fan. The suction nozzle is rotatably provided on the cleaner body via a hinge mechanism. The clutch mechanism is coupled to the hinge mechanism by a link mechanism.

According to one embodiment, a light emitting device includes: a substrate a back face side of which is disposed on a mounting member; a plurality of light emitting elements mounted on a surface side of the substrate; and a power supply terminal provided on the surface side of the substrate and electrically connected to the light emitting elements. The power supply terminal is connected to electrical connecting units by elastic pressing force directed from the surface side of the substrate to the mounting member side. A mechanical fixing unit has a pressing portion brought into contact with the surface side of the substrate. The mechanical fixing units fix the substrate to the mounting member with use of elastic pressing force of the pressing portions directed from the surface side of the substrate to the mounting member side.
