Abstract: A compact magnetic object detection device with high degree of freedom for installation can be provided. The magnetic object detection device includes magnetic field generating mechanism for radiating an alternating magnetic field in a vicinity space; one or a plurality of loop antennas which convert the magnetic field in the vicinity space into an electric signal; determining mechanism for analyzing an existence of magnetostriction and determining an existence of a magnetic object, the magnetostriction generated by the magnetic object existing in the vicinity space based on the electric signal of each of the loop antennas. An installation member, attached with at least the magnetic field generating mechanism and each of the loop antennas, has a pole shape.

Abstract: The present invention discloses: a forgery-preventive identification medium before recording comprising: a substrate containing identification elements, and a magnetic layer for magnetic signal recording, formed at the predetermined portion of the substrate, wherein the magnetic layer contains at least a MnBi magnetic powder; and a method for ascertaining the genuineness thereof.

Abstract: The present invention discloses:

Abstract: A non-contact type data carrier label has a data carrier for storing information and a support member for holding the data carrier, and it is able to attach to a product. The support member has a holding portion for holding the data carrier and paste portion to be pasted on the product in a attachable/detachable manner. A releasable type adhesive layer is formed on the support member. Thus, the data carrier label can be attached to and detached from the product more easily compared with that of conventional one.

Abstract: An adhesive label includes a label base formed of a translucent resin film, an adhesive layer provided on one surface of the label base, and a release liner attached to the adhesive layer. Slits are formed in the release liner to define an initial release-liner portion and a final release-liner portion. In the state in which the initial release-liner portion is peeled off, the adhesive layer can be partially exposed, and printing is effected on the exposed surface of the adhesive layer.

Abstract: An information indicator used for a tire production control label or the like is provided with a film-type substrate formed of a heat-resistant resin. An information indicating surface onto which a recognizable indication indicating specified information is printed is formed on one surface of the substrate, and a pressure sensitive adhesive layer is formed via a primer layer on the other surface of the substrate. The information indicating surface is formed so as to have a surface roughness whose arithmetical mean deviation of the profile determined in JIS B 0801 lies between 0.5 and 5 .mu.m, and an indication such as a bar code, characters, figures, symbols or drawings is attached to the information indicating surface. With the information indicator formed in this way, the indication does not become blurred or erased even under the high temperatures and high pressures during vulcanization.

Abstract: A DNA polymerase from Thermus thermophilus which retains at least 60% of its activity when placed at pH 8.0 and 85.degree. C. for 2 hours is disclosed. The DNA polymerase has a pH optimum of about 8.0, a temperature optimum of about 75.degree. C., a mass of about 85 to 95 kDa and an optimal saline concentration of about 20-60 mM NaCl.

Abstract: A DNA polymerase with excellent thermostability is provided. The DNA polymerase retains at least about 60% of its activity when placed at pH 8.0 for 2 hours at 85.degree. C.
