摘要： An amplifier comprised of a field effect transistor whose gate electrode is adapted to receive an input signal. An impedance converter couples the input signal to the gate electrode of the field effect transistor, the impedance converter being formed of n impedance converting stages, each stage having a relatively low output impedance. A voltage limiting circuit is connected between the source of input signal and the gate electrode of the field effect transistor so as to limit the forward biasing of the field effect transistor. This voltage limiting circuit includes m voltage-limiting elements, wherein n and m are integers (1, 2, 3, . . . ) and n is equal to or greater than m. In a preferred embodiment, the amplifier is formed of two field effect transistors connected in push-pull relation, each field effect transistor being provided with an impedance converter and a voltage-limiting circuit as described above.

摘要： When content data are distributed from an information center via a predetermined communication line to a terminal apparatus loaded with a recording medium recorded with its identifier and prepaid information, the information center manages the usable remaining amount of money in the recording medium loaded in the terminal apparatus and updates this usable remaining amount of money every time content data are distributed. Further, if the usable remaining amount of money is smaller than the price of the content data distributed from the information center, the information center instructs the terminal apparatus to load another recording medium having a usable remaining amount of money sufficient to cover the content data to be distributed. Still further, a remaining recordable capacity of a recording medium loaded in the terminal apparatus is transmitted to the information center, and the information center compares the remaining recordable capacity with the size of the data content to be distributed. If the remaining recordable capacity is smaller than the size of the content data, the information center instructs the terminal apparatus to load a new recording medium having a recordable capacity enough for the content data to be distributed.

摘要： A plate made of a magnetic material is secured to an optical disk so that it closes a central hole formed in a disk substrate. An optical disk chucking mechanism for chucking the optical disk to a disk table attracts the magnetic plate by the magnet to cause a platen to abut to the disk substrate and a tapered portion to abut to the inner side of the central hole so that the optical disk is restricted in position and is held. The optical disk and optical disk chucking mechanism restrict the loading position of the optical disk on the disk table independently of the mounting position of the magnetic plate on the disk substrate.
