A structure of storing a vehicular seat according to one aspect of the invention is constituted by a seat detachably connected to a support base, and a storing space capable of storing the seat detached from the support base. The seat includes an engaging member is fixed to the support base by engaging an engaging portion provided at the support base. The storing space includes a bottom wall, side walls erected to an upper side from two left and right side edges of the bottom wall, and a depth wall erected from a depth edge of the bottom wall to the upper side, and is constituted to slide to store the seat. The seat includes fixing means at predetermined positions inside of the storing space. The fixing means are formed by shapes to slidingly receive and to fix the engaging member of the seat.

A frequency spectrum analyzing apparatus for performing a frequency spectrum analysis with respect to a detected value of an operating parameter of an internal combustion engine in synchronism with rotation of the engine, is provided. The operating parameter is sampled at predetermined time intervals, and a sampled value is converted to a digital value. Intensities of first and second elements are calculated with respect to a predetermined number of the sampled values. The first elements and second elements respectively correspond to a plurality of frequency components contained in the detected value, and a phase of the second element differs from a phase of the first element by 90 degrees. Frequency component intensities corresponding to the plurality of frequency components are calculated in synchronism with rotation of the engine, using the first element intensities and the second element intensities. The frequency component intensities are calculated by replacing a part of an integrated value of the first element intensities, and a part of an integrated value of the second element intensities respectively with corresponding preceding calculated values, when an rotational speed of the engine is higher than or equal to a set threshold value.

In a portable phone, a signal received by a GPS antenna passes through a SAW filter and is amplified by an LNA. An addition section adds a cancellation signal generated by a cancellation signal generation section to the amplified signal to cancel noise superimposed on the received signal.

An inexpensive, productivity-enhanced single-phase AC synchronous motor in which stabilized synchronous pull-in can be carried out by suppressing generation of counter torque during a starting operation. Starting operation is performed while the energizing range of motor current is suppressed such that the energizing direction of motor current waveform lagging in a phase behind the output waveform from a detection sensor (17) is switched at at least the zero cross point of the output waveform from the sensor when the number of revolutions of a permanent magnet rotor (1) reaches a predetermined number of revolutions in the vicinity of the synchronous number of revolutions.
