Abstract: Eine Ladevorrichtung (10) ist eine Vorrichtung zum Durchführen einer Aufladung einer Sekundärzelle in einem elektronischen Gerät und weist ein Detektionsmittel (12), ein Zeitmessmittel (13), ein Spannungserfassungsmittel (12) sowie ein Steuermittel (14) auf. Das Detektionsmittel (12) detektiert, ob eine elektrische Verbindung mit dem elektronischen Gerät hergestellt wurde. Das Zeitmessmittel (13) misst anhand der Detektion durch das Detektionsmittel (12) eine bestimmte Zeit, während der eine Erhaltungsaufladung durchgeführt wird. Das Spannungserfassungsmittel (12) erfasst die Spannung der Sekundärzelle (25). Das Steuermittel (14) bestimmt anhand der Spannung, die vom Spannungserfassungsmittel (12) zu einem Zeitpunkt, zu dem die vom Zeitmessmittel (13) gemessene bestimmte Zeit verstrichen ist, erfasst wird, ob eine Schnellaufladung durchgeführt werden soll oder nicht.

Abstract: Digital audio data with error detection bits added thereto is inputted to an error detecting and correcting device (4). The correcting device (4) corrects an error when the error is detected in the digital audio data. The digital audio data outputted from the error detecting and correcting device (4) is inputted to an impulse noise suppressing circuit (6). The suppressing circuit (6) operates for a predetermined time period when the correcting device (4) detects an error.

Abstract: In some cases, constant directivity of a speaker system is desirably obtained in a wider frequency range. However, a speaker system using a constant directivity horn is frequently used in combination with a box speaker containing a woofer unit. Such a system becomes large in size. Furthermore, constant directivity is desirably obtained in a lower frequency. A speaker system 10 includes an enclosure 20, a first speaker unit 30 for low frequency and a plurality of second speaker units 31, 32, and 33 for high frequency. The enclosure 20 includes a front plate portion 21 which is a baffle plate and a rear plate portion 23. A length of the rear plate portion 22 in a first direction perpendicular to a forward and backward direction is shorter than a length of the front plate portion 21 in the first direction. The first speaker unit 30 and the second speaker units 31, 32, and 33 are mounted to the front plate portion 21. The plurality of second speaker units 31, 32, and 33 are arranged in the first direction. Vibration plates of the plurality of second speaker units 31, 32, and 33 are located in the vicinity of the front plate portions 21 in the forward and backward direction.

Abstract: A device 1 for measuring a propagation time of a sound wave comprises a sound source means 11 and a calculation means 12 . The sound source means 11 outputs a time stretched pulse as a sound source signal input to a speaker 3 . The calculation means 12 calculates a cross-correlation function of the time stretched pulse and the sound signal which is output from the speaker 3 and is received in a microphone 4 . Based on the cross-correlation function, the propagation time of the sound wave between the speaker 3 and the microphone 4 is found.

Abstract: A wide dispersion speaker system 1 comprises a cone type speaker unit 2, and a restricting element 10A. The restricting element 10A is provided with a center hole 11 at a center section thereof, and a peripheral hole 12 located outward relative to the center hole 11. The restricting element 10A has an annular sound travel inhibiting portion 19 positioned radially outward relative to the center hole 11 and radially inward relative to the peripheral hole 12. An outer end in a radial direction of the sound travel inhibiting portion 19 is positioned at a substantially middle point between an outer end in the radial direction of the center hole 11 and an outer end in the radial direction of the peripheral hole 12 or positioned radially outward relative to the substantially middle point.

Abstract: A receiving unit ( 2 ) receives a modulated signal resulting from modulating a carrier signal with a digital encoded train resulting from error-correction encoding a digital signal train. A demodulating unit ( 4 ) demodulates the digital encoded train from the received modulated signal. A decoding unit ( 8 ) decodes the digital signal train from the demodulated digital encoded train. The receiving unit ( 2 ) outputs a received-signal strength indicative signal indicative of the received-signal strength of the modulated signal. During demodulating, a bit error rate computing unit ( 18 ) of the decoding unit ( 8 ) computes a bit error rate. The received-signal strength indicative signal and the bit error rate are inputted to a control unit ( 14 ), and, on the basis of these inputs, it is judged which one of the receiving conditions defined by received-signal strength indicative signals and bit error rates, the current receiving condition corresponds to.
