Abstract: A receiving device includes a storing unit that stores information on whether a function of a program provided via a network is permitted to be used; a receiving unit; a first a receipt control unit that receives, using the receiving unit, before receiving a program via the network, function information indicating a function used in the program; a determining unit that determines whether to receive the program, by comparing function information received by the first receipt control unit and information stored by the storing unit; a second receipt control unit that receives, using the receiving unit, the program via the network if the determining unit determines to receive the program, and that cancels receipt of the program via the network if the determining unit determines not to receive the program; and an executing unit that executes the program received by the second receipt control unit.

Abstract: The present invention provides a technique of determining, in a receiving device or a relay device, using a simple method and within a short time, whether a program provided via a network is a program causing security concerns. Program inspection device 20a pre-inspects the content of a program provided to mobile phone 50 via a network, and generates inspection result data 202 containing functions contained in the program and information on resources accessed when the program is executed. Mobile phone 50 has security management table 507a registering information for each function on whether the function may be used and information on whether a resource may be accessed for each resource. Mobile phone 50 compares inspection result data 202 of a program received via a network and security management table 507a, and thereby confirms whether the program causes security concerns when it is executed.

Abstract: This invention provides a surface mounting type planar magnetic device comprised of upper ferrite magnetic film, lower ferrite magnetic film and a planar coil interposed therebetween. For applying surface mount technology, an opening is formed in the upper ferrite magnetic film above a coil terminal portion and then, an external electrode conductive with the coil terminal portion through the opening is formed on the upper ferrite magnetic film. Further, this surface mounting type planar magnetic device is of a thin structure and can be mounted on the surface of a printed board. Its power loss is small, its inductance is large, its frequency characteristic is excellent, the disparity of the characteristic is small and its reliability is excellent.

Abstract: An apparatus for reproducing a signal recorded, in the form of a perpendicular signal magnetization, on a perpendicular magnetic recording layer backed with a high permeability layer of a magnetic recording medium. A thin-film magnetic material is disposed to face the recording layer so that an enlarged magnetized region is formed in the high permeability layer, which includes the position at which the magnetic material faces the recording layer. In this region, magnetic variation occurs in response to the signal magnetization of the recording layer at the position the magnetic material faces the recording layer. A detecting member such as a coil is disposed in the proximity of the magnetic material so as to be magnetically coupled to the enlarged magnetized region of the high permeability layer. The detecting member is used as a tuning element of a tuning circuit supplied with high frequency energy.
