| 20090086859 | RECEIVING UNIT RECEIVING DIGITAL TELEVISION BROADCASTING - In a receiving unit, an AGC circuit controls the gain of a high frequency amplifier based on an output signal of a mixer, that is, an intermediate frequency signal obtained before an unnecessary frequency component is removed by a BPF. Therefore, deterioration in the distortion characteristic of the mixer can be suppressed more effectively than a conventional case where the gain of the high frequency amplifier is controlled based on an intermediate frequency signal that has passed through the BPF and amplified by an intermediate frequency amplifier. | 04-02-2009 |
| 20090079880 | Television Tuner - A correction circuit comprised of a capacitor and a switch is attached to a resonator such that a single resonance circuit is used to cover the television signals of a plurality of bands. Furthermore, the number of the components in the tuner circuit is reduced. A television tuner functions to receive a television broadcast signal divided into a plurality of frequency bands for conversion into an intermediate frequency signal of a predetermined frequency. The television tuner includes a resonance circuit controlling a frequency of a local oscillation signal which oscillates within a predetermined frequency band. During reception of a first frequency band, a tuning voltage is applied to a variable circuit element included in the resonance circuit to control the frequency of the local oscillation signal. During reception of a second frequency band, the tuning voltage is applied to the variable circuit element included in the resonance circuit and a correction control signal is applied to a non-variable circuit element connected to the variable circuit element to control the frequency of the local oscillation signal. | 03-26-2009 |
| 20080265837 | CONNECTOR DEVICE, METHOD OF MANUFACTURING THE SAME, AND BATTERY PACK USING THE SAME - A connector device includes a circuit board and a connector body, and the connector body includes a housing and a connection terminal provided inside the housing. A silicon resin is applied to fill a gap between the connector body and the circuit board. The application of the silicon resin can prevent a mold resin used to seal the connector device and a battery pack body from entering from the gap into the housing. Thereby, a connector device reliably establishing conduction and a battery pack applying such a connector device can be obtained. | 10-30-2008 |
