摘要： When configuring a film antenna for receiving a circular polarized wave, at least one loop antenna is formed on a transparent plastic film and, at the same time, a non-powered element constituted by a wire-shaped conductor independent from the antenna conductor configuring the loop is arranged near this loop antenna. The non-powered element arranged on the side of the loop antenna is configured by a first part and a second part. The first part is made close to the loop antenna in a substantially parallel state. When a monopole antenna is used in place of the loop antenna, by combining this with a wire-shaped conductor orthogonal to this, it becomes possible to receive a circular polarized wave by a configuration providing a power transfer part between the two. It is also possible to configure a composite antenna by mounting another antenna on the transparent plastic film. This antenna can be used as an antenna of a navigation system.

摘要： An object of the invention is to receive a weak signal with high sensitivity and reduce distortion and signal suppression when a strong interference signal exists. When a high-frequency signal received by an antenna is to be amplified by an antenna amplifier and when an interference wave of high field strength exists, a switch circuit is switched by an output switchover circuit from the output of an amplifier to a through-circuit. The through-circuit guides the high-frequency signal, directly to the output side without passing through the amplifier. When the switching operation of the switch circuit is performed based on low-frequency components which are highly correlated with distortion components due to intermodulation, the switching operation can be performed more adequately. Noises can be reduced by performing a smoothing process on the switching operation, and the use of an inverting amplifier can prevent occurrence of oscillation.

摘要： An audio broadcast receiving apparatus and an audio broadcast receiving method implemented by the audio broadcast receiving apparatus are disclosed. A tuner simultaneously receives a radio wave in a specific frequency band of the analog audio broadcast and a radio wave of the digital audio broadcast transmitted in parallel with the analog audio broadcast in the specific frequency band. A demodulator retrieves the intended audio information by demodulating the signal received by the tuner. An analog receiving signal bandpass filter selectively passes the receiving signal corresponding to the analog audio broadcast radio wave. An analog receiving signal amplifier outputs an output signal representing an amplified receiving signal that has passed the analog receiving signal bandpass filter to the demodulator, and the gain of the amplifier is controlled in accordance with the level of the same output signal. A digital receiving signal bandpass filter selectively passes the receiving signal corresponding to the digital audio broadcast radio wave. A digital receiving signal amplifier amplifies the receiving signal that has passed through the digital receiving signal bandpass filter with a gain controlled in accordance with the level of the same output signal and outputs the amplified signal to the demodulator.

摘要： An intermediate frequency detection circuit of a superheterodyne type radio receiver is disclosure which includes a logic circuit inputted with a signal indicating the level of an intermediate frequency output and a signal indicating the level of a high frequency output of the receiver. This logic circuit generates a indication of the reception of a broadcasting wave when the intermediate frequency output is high and the high frequency output is low. This intermediate frequency detection circuit avoids the erroneous detection due to spurious signals and likewise renders the pulse width of the detection signal approximately constant thus making this circuit suitable for use with automatic channel selection.

摘要： A heating line pattern structure is provided, in which the effect of the heating lines of a defogger on an antenna for a TV broadcast especially for a digital TV broadcast may be decreased. The defogger is structured by arranging heating lines between bus bars on both sides. The portion of an uppermost heating line in proximity to the monopole antenna are folded rectangularly at a regular interval to form a meander shape. One lateral heating line is extended under the meander-shaped heating line portion, and is connected to a vertical heating line to which four lateral heating lines are connected together.
