摘要： PROBLEM TO BE SOLVED: To perform authentication by the user (subscriber) without providing an authenticating function in all subscriber terminal apparatuses. SOLUTION: An access control method is the method for controlling the access of the logical links by a computer concerning a subscriber communication network where access with the plurality of logical links is performed to a station side device (1) from home side devices (2) to which the subscriber terminal apparatuses (3a, 3b) are connected. Authentication is performed with a subscriber authentication terminal apparatus (6) connected to the home side devices (2) via the subscriber communication network. When the authentication is successfully performed, the access of the logical links related to the subscriber authentication terminal apparatus (6) which successfully performs the authentication, is permitted.

摘要： PROBLEM TO BE SOLVED: To provide a rectifier element capable of improving breakdown voltage while reducing stationary loss, and a manufacturing method thereof. SOLUTION: The rectifier element 10 includes an n - semiconductor layer 2 consisting of a wide band gap semiconductor; Schottky electrodes 3 and 5 forming Schottky contact with the n - semiconductor layer 2; and a cathode electrode 4 capable of applying potential different from that of the Shottky electrode 5 and electrically connected to the n - semiconductor layer 2. The height of the Schottky barrier between the Schottky electrode 5 and the n - semiconductor layer 2 is higher than the height of a Schottky barrier between the Schottky electrode 3 and the n - semiconductor layer 2. The rectifier element 10 can select a state where the difference in potential between the Schottky electrodes 3, 5 and the cathode electrode 4 changes, thereby applying a current between the Schottky electrode 5 and the cathode electrode 4 and a state where the n - semiconductor layer 2 between the Schottky electrode 5 and the cathode electrode 4 is made into a depletion layer to disconnect a current path.

摘要： PROBLEM TO BE SOLVED: To provide a camera device which can balance temperature difference and humidity difference between the inside of the case and the open air for preventing dew condensation in the inside of the case. SOLUTION: This camera device has a vent 7P formed in the wall of the case 7 substantially above and/or below the CCD substrate 4 provided in the case 7 and incorporates a material (e.g. boafluon:(R)) 6 which cuts off water in the open air that allows passing the moisture to pass. Thus, the temperature difference and the humidity difference can be balanced with the outside air through the vent 7P. Since the vent 7P is provided near the CCD substrate 4, it can also play the role of radiating the heat of the substrate 4. Furthermore, since the material 6 has the function shielding against the outside water, such as raindrops, the camera can be protected from having its functions deteriorate due to the water entering it.
