    摘要： A recording apparatus for modulating a master key used for encrypting main data in a pit-width direction by changing a light amount of a laser beam to then record it on an optical recording medium and records the main data encrypted by using the master key with correcting the main data so as to have a certain pit width and a pit length so that a jitter resulting in intersymbol interference of adjacent pits should be reduced. A reproducing apparatus for reproducing the recorded optical recording medium, and to thereby prevent an optical recording medium from being duplicated by an illegal copy.

    摘要： An antenna for wireless apparatus which is placed in the vicinity of a conductive object is disclosed. The antenna for wireless apparatus includes a GND plate, a conductive plate parallel to the GND plate, two antenna elements, and two raising conductive plates. Each of the antenna elements includes a short-circuit conductive body and a radiation plate placed at an edge of the short-circuit conductive body. The two antenna elements are placed substantially parallel to a side surface of the conductive object with a distance of a half wavelength of a radio wave to be transmitted and received. The two raising conductive plates are placed close to the two antenna elements respectively and raise the conductive plate from the GND plate to a predetermined height.

    摘要： A wireless communication module is arranged such that a radio frequency circuit board stands vertically on a first earth plate. The radio frequency circuit board includes first and second radio frequency transmission and reception circuits at both end portions, respectively. The radio frequency circuit board includes a second earth plate serving as a grounding electric potential of the radio frequency transmission and reception circuits. Feed lines from the radio frequency transmission and reception circuits are connected to the first earth plate, respectively. Ground lines of the feed from the radio frequency transmission and reception circuits, respectively, are connected to the second earth plate. Thus, vertical exciting currents flow at both end portions of the second earth plane, enabling transmission and reception of vertical polarization waves.
