    摘要： An integrated circuit is equipped with a reception mixer and a signal generator. A multistage delay circuit generates a plurality of clock pulses in response to a reception carrier signal. A phase detection unit detects differences between a voltage level of a specific clock pulse and voltage levels of a predetermined number of clock pulses generated prior to the specific clock pulse to thereby detect a predetermined phase of the specific clock pulse. A selector of a clock generation unit outputs a plurality of selection clock pulse signals respectively having a plurality of phases from the clock pulse signals. A first signal synthetic logic circuit performs logical operations on the selection clock pulses to thereby generate local signals supplied to the reception mixer.

    摘要： According to one embodiment, an information recording/reproducing device includes a recording layer and a driver section. The recording layer has a first layer including a first compound. The first compound includes a mixed crystal of a first oxide containing a first metallic element and a second oxide. The second oxide has a crystal structure being same as the first oxide and contains a second metallic element different from the first metallic element. The driver section is configured to produce state change in the recording layer to record information by at least one of application of voltage to the recording layer and passage of current to the recording layer. Composition ratio of an element having a smaller ionic radius of the first and second metallic elements is not less than percolation threshold of a lattice formed of ions of the first and second metallic elements based on the crystal structure.

    摘要： In an IC tag, when a semiconductor integrated circuit device is activated, an operation control unit sets existence/nonexistence of a communication distance limitation for reducing a communication distance to a state management unit. If the communication distance limitation is not set, a switch unit is turned ON and a demodulated command is inputted from a command demodulation circuit to a command decode unit. If the communication distance limitation is set, a power intensity monitor unit judges whether the power of a rectification circuit is a predetermined arbitrary field intensity or more. If the power is smaller than the predetermined arbitrary field intensity, the switch unit is turned OFF and various commands demodulated by the command demodulation circuit are not inputted to the command decode unit. As a result, the semiconductor integrated circuit device does not operate.

    摘要： An optical recording medium includes an optical recording layer, a separating layer formed on a reproducing light incident side of the optical recording layer, and a phase-change reproducing layer formed on the reproducing light incident side of the separating layer, absorbance of which phase-change reproducing layer is changed depending on whether a state of the optical recording layer is a recording mark or a space. A transfer portion to which a state of the optical recording layer is transferred is formed in a portion having high absorbance of the phase-change reproducing layer by irradiation with reproducing light, while a portion of the phase-change reproducing layer other than the transfer portion is kept in a state optically differing from the transfer portion.
