    摘要: A lubricant sheet for a magnetic tape cassette characterized in that at least one side of a base incorporating an antistatic agent is provided with a release type silicone coating. This lubricant sheet combines the transparency derived from the use of the clear base and coating materials with the low friction characteristic and the antistatic property to suit the application as such for transparent tape cassette cases.

    摘要: The present invention provides a magnetic head of which magnetic core is composed of thin plates of a high magnetic permeability, each provided with an adhesive layer comprising a granular substance. In such structure, the stress relaxation achieved by said granular substance prevents the loss of effective magnetic permeability of said core, thereby improving the high frequency characteristics. Also the presence of said granular substance realizes a hardness in the vicinity of said adhesive higher than that of said thin plates of a high magnetic permeability, thereby improving the abrasion resistance of said core. Furthermore said adhesive layer is rendered satisfactorily thinner than said thin plate to prevent the loss of sensitivity. Furthermore a fixing member for supporting said core is made of such a composition as to be evenly abraded with said core, thereby preventing deformation of the head resulting from abrasion by the recording medium and thus enabling to maintain the initial electromagnetic converting characteristics over a prolonged period.

    摘要: Unlike the technology for a program downloaded through conventional broadcast waves, in the case of downloading a program via a network, there is a possibility that such program will be activated without noticing that the program is tampered with. For this reason, when a program is downloaded via a network, a file hierarchy for the program located on a server is constructed in a local area of a terminal. Subsequently, the authentication of the program is performed with respect to the file hierarchy constructed in the local area, and the credibility of the program is guaranteed.
