    Abstract: A multifrequency antenna, which may be used as a built-in antenna of a small and thin radio communication terminal, such as a mobile telephone, is able to receive radio waves of multifrequency bands without enlarging the shape thereof. The antenna is structured using a main mode resonance frequency and a high-order mode resonance frequency of a single-frequency plane antenna with a short-circuit plate. Specifically, a radiator conductor plate in an optional shape is arranged on a ground plate, and the radiator conductor plate is connected to the ground plate via the short-circuit plate. Power is supplied to the radiator conductor plate from a power-feeding source via a feeder cable. In the radiator conductor plate, a cut portion for shifting the high-order mode resonance frequency to the location at a predetermined distance from the short-circuit plate is formed, and the high-order mode resonance frequency is shifted into a desired band by this cut portion. Consequently, the multifrequency antenna operates at least at two frequencies: the main mode resonance frequency, and at least one high-order mode resonance frequency shifted by the cut portion. Thus, a small and thin multifrequency antenna can be realized at a low cost without a concomitant increase in both the mounting area and the mounting volume of the multifrequency antenna.

    Abstract: A P-type thermoelectric material consists essentially of iron disilicide, metallic manganese and metallic aluminium dissolved in or alloyed with the iron disilicide, and silicon oxide and/or aluminum oxide present in the iron disilicide. The manganese is contained in an amount of from 1.67 to 4.1 atomic % with respect to a sum of atoms of iron and silicon constituting the iron disilicide, the metallic manganese and the metallic aluminum taken as 100 atomic %, and the metallic aluminum contained in an amount of from 1.33 to 3.33 atomic % with respect thereto, and a sum of the metallic manganese and the metallic aluminum in an amount of from 4.0 to 5.34 atomic % with respect thereto. The P-type thermoelectric material having such a composition produces a thermoelectromotive force equal to or greater than those of the conventional P-type thermoelectric materials comprised of iron disilicide, and it exhibits a mean resistivity equal to or smaller than that of the N-type thermoelectric material. Hence, a thermocouple including the P-type thermoelectric material and the N-type thermoelectric material can be remarkably enhanced in the performance as a whole.

    Abstract: A vehicle includes a motor generator and an engine generating driving power for running, and an ECU for controlling the motor generator and the engine. If user request power and a vehicle speed are substantially constant when inertial running control is selected by a user, the ECU causes driving power variation operation to be performed on the motor generator and the engine in which the motor generator and the engine are switched between a low output state and a high output state. The vehicle runs with inertial force of the vehicle in the low output state. As a result, energy efficiency during vehicle running can be improved.

    Abstract: A vehicle includes an engine and a motor generator generating driving power for running, and an ECU for controlling the engine and the motor generator. If user requested power and a vehicle speed are substantially constant when inertial running control is selected by a user, the ECU causes continuous driving power operation to be performed on the engine in which the engine is driven to continuously generate constant driving power, and causes driving power variation operation to be performed on the motor generator in which the motor generator is alternately switched between a low output state and a high output state in terms of driving power, thereby running the vehicle. As a result, energy efficiency during vehicle running can be improved.
