    摘要： A wireless communication device in a data collection system starts measuring a time when the wireless communication device receives a wireless signal from a data collection device. The wireless communication device changes the wireless channel, transmits a detection signal for detecting the data collection device, and starts measuring a time after transmitting the detection signal when the wireless communication device is unable to receive a next wireless signal from the data collection device even after passage of a predetermined time since the wireless communication device has previously received the wireless signal. The wireless communication device changes the wireless channel to be used, depending on whether the wireless communication device has received a response signal from the data collection device in response to the detection signal within a predetermined time.

    摘要： An amplifying apparatus includes a magneto-resistive device which has a magnetic free layer, a magnetic pinned layer having a magnetic moment larger than that of the magnetic free layer, and an intermediate layer provided in between the magnetic free layer and the magnetic pinned layer. The amplifying apparatus has a first electrode layer provided in a magnetic free layer side of the magneto-resistive device, and a second electrode layer provided in a magnetic pinned layer side of the magneto-resistive device. The amplifying apparatus further includes a direct-current bias power-source for applying a direct-current bias to the magneto-resistive device, and a load resistor. The amplifying apparatus continually causes the change of a magnetization direction of the magnetic free layer to make the magneto-resistive device show negative resistance, and thereby amplifies an input signal.

    摘要： Localized temperature increases inside integrated circuits due to heating at operation are prevented or controlled by electronic devices or wirings with CPP (current-perpendicular-to-plane) structure which has a current cooling effect. The CPP structure refers to a structure comprising a columnar electrically conductive portion and an insulator portion surrounding the conductive portion. The columnar portion is formed from the multilayered structure in a direction perpendicular to the plane of the layers, so as to allow a current to flow from an upper layer to a lower layer (or vice versa). The cooling effect is induced by current at the interface (or a plural of interfaces) of appropriately selected different kinds of materials (which are conductive substances in general, such as metals, semiconductors, and alloys thereof) in the columnar portion due to the Peltier effect when a current flows through the column. Temperature in minute range is detected by thermocouple with CPP structure. The thermocouple has two interfaces of different materials with a proper combination. When a temperature difference exists between two interfaces, a voltage which corresponds to product of the temperature difference and the Peltier coefficient at the interface is produced. In the same manner, the intensity of inferred can be also measured.
