摘要:
Provided is a corrosion-resistant and wear-resistant member where a thermal-sprayed layer having corrosion resistance and wear resistance is formed on a surface of a metallic member which is brought into contact with a resin which generates a highly corrosive gas. Also provided is a thermal-spraying powder. The highly corrosion-resistant and wear-resistant member having a thermal-sprayed layer is one obtained by thermally spraying metallic powder on a metallic base material to form a thermal-sprayed layer on a surface of the metallic base material. The member is characterized in that the thermal-sprayed layer is a composite boride cermet of a tetragonal Mo2 (Ni,Cr)B2-type or a tetragonal Mo2 (Ni,Cr,V)B2-type. The powder for forming a thermal-sprayed layer is made of a composite boride cermet of a Mo2 (Ni,Cr)B2-type and comprises 4.0 to 6.5 mass % of boron, 39.0 to 64.0 mass % of molybdenum, and 7.5 to 20.0 mass % of chromium, a balance being 5 mass % or more of nickel and unavoidable elements.

The present invention is the aqueous floor polishing composition which contains the polyoxyalkylene diester compound represented by the following general formula (1) and does not contain the phosphorus-containing plasticizer. R1 and R2 represent each independently alkyl groups having 1 to 24 carbon atoms, m represents an integer from 2 to 4, n represents a number from 2 to 40.The aqueous floor polishing composition of the present invention does not contain the phosphorus-containing plasticizer. Therefore, it does not affect the environment negatively, in spite of having excellent leveling properties, lustering properties and heel mark resistance properties.

摘要:
A magnetic recording medium comprises, on a substrate, a recording auxiliary layer, a recording holding layer, recording control layer, and a recording layer. The recording layer is constructed by using a ferri-magnetic material having perpendicular magnetization. The data can be recorded at a super high density by using the recording and reproducing head of the present invention, because the recording layer has the perpendicular magnetization. The disappearance of data, which would be otherwise caused by the thermomagnetic relaxation phenomenon, is suppressed after recording the data, because the recording layer has large coercive force at the room temperature. The data, which is recorded at the super high density on the magnetic recording medium, can be reproduced by using a magnetic resistance element carried on the recording and reproducing head.

An information-recording method and an information-recording medium which make it possible to improve overwrite characteristics in the high speed recording, especially archival overwrite characteristics for overwriting information after retaining the medium in a high temperature environment for a certain period of time, and an information-recording apparatus based on the use of the same are provided. The information-recording method comprises overwriting a random pattern with light-beams having a predetermined recording power and a variety of erasing; powers; reproducing the random pattern to determine a minimum value Pb1 and a maximum value Pb2 of the erasing power obtained when the pattern, in which a reproduction jitter exceeds a predetermined threshold value, is erased; determining an optimum erasing power Pb from the minimum value Pb1, the maximum value Pb2, and a relational expression represented by Pb=α×Pb1+(1−α)×Pb2; and recording the information with the determined optimum erasing power Pb. The value of α is previously recorded on the information-recording medium. The information-recording apparatus has a Pb-calculating control unit which reads the value of α when the optimum erasing power Pb is determined.
