摘要： An audio reproduction apparatus includes: a delay equalizer (301), a delay equalizer (303), a level adjuster (314), and a level adjuster (317). The delay equalizer (301) equalizes an FL signal using an equalizer characteristic EQ9 that converts a characteristic of an audio signal perceived as being reproduced at a position of an FL speaker (104) with respect to a viewing position to be perceived as being reproduced at a position of a virtual speaker (201) with respect to the viewing position. The delay equalizer (303) equalizes the FL signal using an equalizer characteristic (EQ12) that converts a characteristic of an audio signal perceived as being reproduced at a position of an SL speaker (106) with respect to a viewing position to be perceived as being reproduced at a position of the virtual speaker (201) with respect to the viewing position. The level adjuster (314) performs level adjustment, using a first coefficient K9, on an output signal of the delay equalizer (301). The level adjuster (317) performs level adjustment, using a second coefficient K12, on an output signal of the delay equalizer (303).

摘要： An internal combustion engine piston includes a piston crown, a thrust-side skirt, an anti-thrust-side skirt, a first apron, and a second apron. The first and second aprons are connected to the thrust-side and anti-thrust-side skirts through connecting sections. Each connecting section has a thickness that gradually increases as followed from a proximal longitudinal end to a distal longitudinal end, wherein the proximal longitudinal end is closer to the piston crown, and the distal longitudinal end is closer to a distal longitudinal end of a corresponding one of the thrust-side and anti-thrust-side skirts.

摘要： An integrated circuit (IC) card capable of a high-speed data transmission to/from a data transmission apparatus having low processing capability. A controlling section generates a data packet by adding management information including information regarding a data length of the data packet, and divides the data packet to generate data blocks. The data length of the data block is designated from the data transmission apparatus. When the data blocks which compose the single data packet are sent to the transmission apparatus a communicating section sends an interrupt signal to the data transmission apparatus if the data block including the management information is to be sent, and does not send the interrupt signal to the data transmission apparatus if a data block not including the management information is to be sent.

摘要： A bandpass filter bandpass-filters an inputted signal X to pass therethrough a partial band of a band of the inputted signal X, and a level correlated white noise generator circuit generates a white noise signal having a level changing according to a level of the inputted signal and correlated to the inputted signal. A signal processing circuit executes a signal processing that includes a predetermined bandpass filtering processing, an echo adding processing, and a level adjustment processing, and that multiplies the inputted white noise signal by a predetermined transfer function, and outputs a processed white noise signal to an adder. The adder adds up the white noise signal from the signal processing circuit and the inputted signal X, and outputs a band-extended signal having an addition result, as an outputted signal.

摘要： A higher harmonic wave generator generates a higher harmonic wave of an inputted audio signal having a predetermined band based on the inputted audio signal. Next, a multiplier modulates an amplitude of a generated higher harmonic wave of the audio signal according to a band signal having a predetermined bandwidth so as to generate an amplitude-modulated signal. A digital bandpass filter bandpass-filters a generated amplitude-modulated signal using a predetermined bandpass characteristic, and outputs a resultant signal as a band-extended signal. Further, an adder adds a bandpass-filtered amplitude-modulated signal to the inputted audio signal, and outputs an audio signal including a band-extended signal in an audio signal of an original sound and having an addition result.

摘要： A spark plug has a cylindrical metal shell, a ground electrode and an insulator fixedly supported within the metal shell with a front end of the insulator extended beyond a front end of the metal shell. The insulator has an axial bore in which a center electrode is placed to form a spark gap with the ground electrode. The front end of the metal shell is generally flush with or somewhat recessed into an inner wall of a combustion chamber of an internal combustion engine when the spark plug is mounted on a cylinder head of the engine. The front end of the insulator extends at least 4.0 mm from the front end of the metal shell.
