One of the difficulties in developing a metallic material which is corrosion resistant to caustic alkaline solutions is that the corrosiveness of these solutions is different depending upon the process for producing the same. The chromium alloyed steel developed according to the present invention, contains, from 29 to 31%, of Cr; not more than 3% of Mo; not more than 0.005% of C; at least one element selected from the group of Nb and Ta in an amount, which follows the equation20.times.C(%).ltoreq.Nb(%)+0.5.times.Ta(%).ltoreq.60.times.C(%);from 0.0005 to 0.02% of Ca and; not more than 0.02% of deoxidation products being present in said chromium alloyed steel and essentially composed of CaO, SiO.sub.2 and Al.sub.2 O.sub.3.Because of the combination of the reduction of C, N and the impurities of the steel with the addition of Nb and/or Ta, the corrosion resistance of the chromium steel is excellent with regard to the caustic alkaline solution produced by every kind of processes. This excellent corrosion resistance is not essentially degraded by the welding of the chromium steel pieces and, further, the ductility and workability of the chromium steel are improved.

Reduced pellets are manufactured by mixing a powdered raw metallurgical ore such as of iron, chromium or manganese with a carbonaceous reducing material obtained by heat-treating anthracite, at temperatures between 600.degree. C and 1000.degree. C and subsequently pulverizing the heat-treated anthracite, pelletizing the resultant mixture and thereafter roasting the pellets.

A radiation image read-out apparatus comprises a read-out section for reading out a radiation image stored on a stimulable phosphor sheet, an erasing section for erasing radiation energy remaining on the stimulable phosphor sheet after image read-out from the stimulable phosphor sheet is finished, a section for releasably holding a sheet feed cassette capable of housing the image-recorded stimulable phosphor sheet and for taking the stimulable phosphor sheet out of the sheet feed cassette toward the read-out section, and a section for releasably holding a sheet housing cassette capable of housing the stimulable phosphor sheet erased at the erasing section. The apparatus also comprises a sheet stacking section for holding a plurality of erased stimulable phosphor sheets having different sizes, selecting the stimulable phosphor sheet having a desired size one at a time from the stimulable phosphor sheets held at the sheet stacking section, and feeding out the selected stimulable phosphor sheet towards the section for holding the sheet housing cassette.

An apparatus for reading out a radiation image stored on a stimulable phosphor sheet comprises a read-out section, a monitor for reproducing a visible radiation image, an erasing section, and a section for releasably holding a magazine housing stimulable phosphor sheets. The apparatus also comprises a first conveyance system for conveying the stimulable phosphor sheets fed out of the magazine to the read-out section, a stacker disposed at the first conveyance system between the magazine holding section and the read-out section, for housing the stimulable phosphor sheets and transferring them one by one to the first conveyance system. A second conveyance system conveys the stimulable phosphor sheets passing through the read-out section to the erasing section, and a third conveyance system returns the stimulable phosphor sheets passing through the read-out section to the stacker. A distributing member distributes the stimulable phosphor sheets passing through the read-out section either to the second conveyance system or to the third conveyance system.

A slaking property of a lime bearing agent for use in the refining, particularly in the injection refining, of a ferrous melt is essentially eliminated by providing the agent with a special form, i.e. an uncrushed, granular form solidified from molten drops. Hydrogen pick up of the ferrous melt from the refining agent is avoided and an excellent refining effect of the ferrous melt is achieved by the refining agent of the present invention.

A method for objectively predicting possibility of metastasis to a cervical lymph node in an early stage for an individual case diagnosed as an oral cavity cancer, and a diagnosis kit to be used in the prediction are provided. The method includes a step of assaying expression amounts of metastasis prediction genes in which the expression amounts are changed between a metastasis group and a non-metastasis group, with respect to a sample collected from a primary legion of the oral cavity cancer. Further, the method includes a step of predicting the possibility of the metastasis by comparing the expression amounts of the metastasis gene group with the expression amounts of the metastasis prediction genes in a metastasis group and/or a non-metastasis group. Herein, the metastasis prediction gene group includes two genes MSR1 (NM_138716.1) and RET (M31213.1).

An apparatus for recording a radiation image on a stimulable phosphor sheet and reading out the stored radiation image comprises a recording section provided with a sheet stacker, a read-out section, and an erasing section disposed on a circulation path of a conveyance system. The sheet stacker is provided with a tray unit comprising a casing and a plurality of trays housed in the casing so that every tray may be positioned on the circulation path, allows the stimulable phosphor sheet to be conveyed by the conveyance system into the tray, holds the stimulable phosphor sheet in the tray, and allows the stimulable phosphor sheet to be conveyed by the conveyance system out of the tray. The sheet stacker is also provided with a conveyance mechanism for taking the stimulable phosphor sheet out of an arbitrary tray housed in the casing, conveying the stimulable phosphor sheet to an image recording position exposed to a radiation, and conveying the stimulable phosphor sheet from the image recording position into an arbitrary tray.
