摘要:
A judgement section (10) and a ratio calculation section (11) in an image processing apparatus input image signals in digital form of n color components forming colors, transferred externally in time series, and calculate conversion parameters indicating change of ratios of signal strength values between input image signals per color component based on a total sum of the ratios of synthesis signal values, each conversion section (12, 13, 14) and a signal range calculation section (15) converts input image signals to output image signal without any change of the ratio of signal strength values between the input image signals based on the conversion parameters, per color component.

摘要:
There is disclosed a nuclear reactor installation. An accumulator-type emergency core cooling system, a gravity-driven core cooling system and an equalizing system for submerging a reactor core are provided within a primary containment vessel containing a reactor pressure vessel in which the reactor core is disposed. These cooling systems are automatically operated sequentially in accordance with the pressure in the reactor pressure vessel without the need for any particular powered source. The primary containment vessel is made of steel, and the interior of this containment vessel is divided into a space containing the reactor pressure vessel and a space containing an operation floor in such a manner that the two spaces are isolated from each other. An opening device is provided between the two spaces so as to communicate the two spaces with each other in the event of an accident, the upper portion of the primary containment vessel being air-cooled while the lower portion of this containment vessel being water-cooled.

The present invention is to provide an improved container rotor for use in a centrifugal separator which can serve different types of the centrifugal separating operation by the employment of a specific rotor which allows three types of bucket to be exchanged readily with one out of the swing type, the angled aperture type and the horizontal aperture type accordingly to the kind of specimen to be separated, which comprises, in combination, a rotor body and a plurality of buckets, wherein the rotor body includes receiving recesses and an opposed pair of supports for receiving operatively the plurality of buckets, the buckets being adapted to afford three different types of centrifugal separating operations, i.e., the swing type, the angled aperture type and the horizontal aperture type.
摘要:
An emergency reactor core cooling structure comprises a flow passage provided on an upper core plate so as to extend downward therefrom into the core. The flow passage has an orifice member at a lower portion thereof. The orifice member has such a portion that the cross-sectional area of the flow passage is made minimal at the orifice member. The flow passage causes the cooling water held on the upper plate by vapor flowing up on an accident to flow down therethrough, whereby the core is cooled rapidly.
