A method of isolating and recovering methacrylic acid from a methacrylic acid-containing reaction product gas resulting from the vapor-phase catalytic oxidation of isobutylene, tertiary butanol or isobutyraldehyde, which comprises introducing the reaction product gas comprising methacrylic acid and various by-products including high boiling substances at a high temperature of 250.degree. to 300.degree. C. into a cooling zone, rapidly cooling the gas therein to a temperature of not more than 100.degree. C. to condense methacrylic acid and thus isolate methacrylic acid, while also converting the high boiling substances to fumes, thereafter introducing the cooled gas containing said fumes into a venturi scrubber, contacting it therein with an aqueous medium to remove said fumes, finally introducing the treated gas into a methacrylic acid-absorbing zone and absorbing methacrylic acid by absorption into an aqueous medium.

A magnetroresistive element formed by laminating a plurality of metallic magnetoresistance effect films having magnetostriction of different signs on a substrate. The magnetoresistive element can be formed to exhibit zero magnetostriction or to exhibit magnetostriction of any desired value. Further, the magnetoresistive element exhibits magnetostriction that changes little with the change in the film composition. The metallic magnetoresistance effect films preferably have positive and negative magnetostriction with an absolute value not greater than 15.times.10.sup.-6.
摘要:
A method of forming a multilayer thin film is disclosed in which a second thin conductive film is deposited on a first thin conductive film uninterruptedly after the first thin film has been deposited on a substrate, the first and second films thus formed are processed so as to form a predetermined pattern, the surface of the second thin film is cleaned by ion etching and a third thin conductive film is deposited on the whole surface of the substrate, and then the second and third thin films are processed so as to have a pattern different from the above-mentioned predetermined pattern. In the case where two thin conductive films different in material and pattern from each other are piled on a substrate, the above method can form a perfect interconnection between the two films and can make very small the contact resistance between the two films. Accordingly, the method is fit to form, for example, a barber pole type magnetoresistive element.

摘要:
The magnetoresistance effect element is of a multilayered structure having at least magnetic layers and an intermediate layer of an insulating material, a semiconductor or an antiferromagnetic material against the magnetic layers, and the magnetoresistance effect element has terminals formed at least on the opposite magnetic layers, respectively, so that a current flows in the intermediate layer. The film surfaces of all the magnetic layers constituting the magnetoresistance effect element are opposed substantially at right angles to the recording surface of a magnetic recording medium. Therefore, the area of the magnetic layers facing the recording surface of the magnetic recording medium can be extremely reduced, and thus the magnetic field from a very narrow region of the high-density recorded magnetic recording medium can be detected by the current which has a tunneling characteristic and passes through the intermediate layer.
