A digital radio broadcasting receiver capable of automatically setting an audio field of reproduced sound in response to a musical genre of an ongoing broadcasting composition is disclosed. Digital radio broadcasting receiver 1 is provided with tuner 2, audio data decoder 3, equalizer 4, parameter memory 5, additional program information decoder 7, genre data selector 8 and control CPU 6. Tuner 2 outputs audio data and additional program information and audio data decoder 3 decodes the audio data. Equalizer 4 adjusts frequency characteristics of the decoded audio data. Parameter memory 5 stores parameters for the frequency characteristics for each musical genre. Additional program data decoder 7 decodes additional program information. Genre data selector 8 selects musical genre data from the additional program information. Parameter memory 5 reads out the parameters to adjust frequency characteristics and provides the same to control CPU 6, which sends the same to equalizer 4.

An oscillating apparatus includes a driver generating a waveform signal based on a stored data for specifying a waveform so as to output the waveform signal to a transducer. A detector detects a phase difference between electric voltage and current supplied to the transducer. A memory unit holds gain data reflecting a characteristic of the transducer. The gain data specify gains corresponding to respective phase differences. An arithmetic unit calculates the frequency of the waveform based on the phase difference detected at the detector and a gain included in the gain data. The oscillating apparatus enables determination of a gain suitable to the transducer in view of the characteristic of the transducer. The frequency of the waveform signal is allowed to follow the change in the resonant frequency in a shorter period. The oscillation can thus be kept well.

摘要:
A method of flip-chip bonding can favorably activate the bonding surfaces and remove oxide films when bonding pads and bumps of a semiconductor chip and a substrate and avoids problems such as the bumps being excessively flattened and the bonds between connection terminals being destroyed by subsequent ultrasonic vibration. The method includes an aligning step 2 that aligns and places in contact bumps or pads of a semiconductor chip and pads or bumps of a substrate, a leveling step 4 that levels the shapes of the bumps by pressing together the semiconductor chip and the substrate with a first predetermined load, a bonding preparation step 6 that applies ultrasonic vibration to the semiconductor chip and/or the substrate so that the amplitude of the ultrasonic vibration gradually increases while the first predetermined load weakens, and a bonding step 8 that bonds the bumps and pads by applying ultrasonic vibration to the semiconductor chip and/or the substrate in a state where the semiconductor chip and the substrate are pressed together with a second predetermined load that is smaller than the first predetermined load.
