    摘要: A method of producing a magnetic recording medium includes forming a underlayer on a base, and successively forming, on the underlayer, a first magnetic layer, a nonmagnetic coupling layer and a second magnetic layer. The first and second magnetic layers are exchange-coupled via the nonmagnetic coupling layer and have antiparallel magnetizations in a state where no external magnetic field is applied on the magnetic recording medium. The underlayer is made of Cr or a Cr alloy having a bcc crystal structure within an atmosphere including nitrogen gas.

    摘要: The present invention aims to provide an adsorbent with superior adsorption performance of 20 wt % or more in a humidity range of 5 to 60 wt % by using a low-cost reagent as the raw material. Aluminum sulfate is used as the Al source, the respective aqueous solutions are mixed to achieve a Si/Al molar ratio of 0.70 to 1.0 in the mixed solution, the pH is adjusted to be 6 to 9 with acid or alkali, the solution is heated at 90 to 110° C. and subsequently subject to desalination treatment in order to synthesize an amorphous aluminum silicate. The obtained amorphous aluminum silicate yields a superior water vapor adsorption performance of 20 wt % or more in a relative humidity of 60%, and can be used as an adsorbent for desiccant air conditioning and as other adsorbents.

    摘要: Provided is an adsorbent having excellent adsorption performance in a medium-humidity range by employing an amorphous aluminum silicate formed from protoimogolite. The amorphous aluminum silicate formed from protoimogolite is synthesized by setting the Si/Al ratio in solution mixing to be of a condition that is higher than synthesizing imogolite or amorphous imogolite, and performing desalting treatment and heating thereto. The obtained amorphous aluminum silicate formed from protoimogolite yields a superior water vapor adsorption performance of 30 wt % or higher at a relative humidity of 60%, and can be used as an adsorbent for desiccant air conditioning.
