Abstract: Disclosed is a meter mounting structure of a motorcycle realizing improvement in visibility of a meter. A meter includes a plurality of displays which are disposed in tandem in a direction of the sight line of a rider and is mounted near a handle. The meter is mounted inclined with respect to a reference plane orthogonal to the sight line such that a lower half portion of each of the displays is positioned closer to an eye point than an upper half portion thereof. Preferably, the meter is mounted such that the lower end of the display on the rear side in the direction of the sight line is disposed in almost the same position as that of the display on the front side in the direction of the sight line in the case where the meter is disposed parallel with the reference plane.

Abstract: In a contents sale system, original contents data are encrypted into encryption-resultant contents data in response to original playback key data. The original playback key data are encrypted into first encryption-resultant playback key data. The first encryption-resultant playback key data are encrypted into second encryption-resultant playback key data in response to an ID of a sale destination terminal apparatus. The encryption-resultant contents data and the second encryption-resultant playback key data are transmitted to the sale destination terminal apparatus. The sale destination terminal apparatus is enabled to decrypt the second encryption-resultant playback key data into the first encryption-resultant playback key data in response to the ID of the sale destination terminal apparatus. The sale destination terminal apparatus is enabled to decrypt the first encryption-resultant playback key data into the original playback key data.

Abstract: A sale destination terminal apparatus is designed for a contents sale system including a host apparatus for feeding contents data. In the terminal apparatus, a first device operates for storing a signal representing an electronic purse having electronic money. A second device operates for, in cases where contents data are copied and transferred from the terminal apparatus to a copy destination apparatus, storing a signal representing a transfer generation number corresponding to a number of times of transfer of the contents data. A third device operates for, in cases where copied contents data are transferred to the terminal apparatus from a copy source apparatus, storing a signal representing a history of transfer of at least one of a copy source ID and sale contents. A fourth device operates for, in cases where the copied contents data are transferred to the terminal apparatus, receiving the copied contents data.

Abstract: A surround signal processing apparatus by which an inputted rear surround signal can be reproduced, together with two-channel front stereophonic signals, through a pair of speakers arranged in front of and in substantially right-and-left symmetry about a listener, in such a way that two sound images of the reproduced rear surround signal can be localized at two predetermined positions relative to the listener. The inputted rear surround signal is processed by a filter. The signal processed by the filter is added to one of the stereophonic signals, and then outputted to one of the pair of speakers. Further, an inversion signal of the filter-processed signal is added to the other of the stereophonic signals, and then outputted to the other of the speakers.

Abstract: Two closed loops including a base bias controlling circuit are provided in a single ended push-pull amplifier. The base bias controlling circuit controls base bias voltages of respective transistors constituting the final stage of the push-pull operation so that a predetermined small amount of collector current flows via each of the collector-emitter paths of the transistors irrespective of the presence and absence of the input signal. Because of the predetermined collector currents, none of the transistors is held at cutoff in operation, thereby preventing the occurrence of the crossover distortion.

Abstract: An angle modulated wave demodulation system demodulates an input angle modulated wave by means of a phase locked loop system which comprises a phase comparator, which is operated responsive to an input angle modulated wave. A voltage controlled oscillator is supplied with a part of the output of the phase comparator which controls its oscillation frequency. The oscillator supplies its oscillation frequency to the phase comparator. The phase locked loop system has a lock frequency range which decreases its width when the level of the input angle modulated wave is below a predetermined level. The portion of this lock range in which the width of the lock range decreases is positively utilized. The voltage controlled oscillator oscillates at a frequency equal to the center frequency of the carrier of the input angle modulated wave, when the phase locked loop becomes unlocked.
