  • Patent number: 8316134
    Abstract: Communication is established between communication terminals arranged in different LANS while realizing dynamic response to reduction in server load, movement of communication terminal, and the like. A relay server is arranged in a LAN and can communicate with an SIP server arranged in a WAN. For instance, a first relay server exchanges account information of the communication terminals in the respective LAN with a second relay server. If exchanged account information is changed in one relay server, the account information after the change is notified to the other relay server. One relay server determines the other relay server based on the exchanged account information and relays communication data between the communication terminals through the other relay server.

  • Patent number: 8315396
    Abstract: An apparatus for generating at least one audio output signal representing a superposition of at least two different audio objects comprises a processor for processing an audio input signal to provide an object representation of the audio input signal, where this object representation can be generated by a parametrically guided approximation of original objects using an object downmix signal. An object manipulator individually manipulates objects using audio object based metadata referring to the individual audio objects to obtain manipulated audio objects. The manipulated audio objects are mixed using an object mixer for finally obtaining an audio output signal having one or several channel signals depending on a specific rendering setup.

  • Patent number: 8314531
    Abstract: In a piezoelectric-actuator driving circuit for driving a piezoelectric actuator, an amplifier circuit amplifies a signal output from a feedback circuit and supplies the amplified signal to a non-inverting amplifier circuit and an inverting amplifier circuit. The non-inverting amplifier circuit amplifies the output voltage of the amplifier circuit with a predetermined gain and applies the amplified voltage to a first terminal of the piezoelectric actuator. The inverting amplifier circuit inverts and amplifies the output voltage of the amplifier circuit with the same gain as that of the non-inverting amplifier circuit and then applies the amplified voltage to a second terminal of the piezoelectric actuator through resistors. The feedback circuit amplifies a difference between voltages at respective ends of the resistor and supplies the amplified difference to the amplifier circuit.

  • Patent number: 8315033
    Abstract: In a capacitor body, a single second capacitor unit is interposed between two first capacitor units. The width direction dimension of each of extended portions of first and second internal electrodes included in the first capacitor unit is larger than the width direction dimension of each of extended portions of third and fourth internal electrodes included in the second capacitor unit. The area of each of the respective portions of a first opposed portion of the first internal electrode and a second opposed portion of the second internal electrode, the respective portions being opposed to each other, is smaller than the area of each of respective portions of opposed portions of the third and fourth internal electrodes, the respective portions being opposed to each other. Thus, a multilayer capacitor has a characteristic that is a combination of a low-ESL characteristic of the first capacitor unit and a high-ESR characteristic of the second capacitor.

  • Patent number: 8312713
    Abstract: An internal combustion engine includes a structure that increases the velocity of exhaust gas. The internal combustion engine includes a branch section arranged to branch a shock wave propagating at a higher velocity than exhaust gas and to guide the branched shock wave, and a reflecting section provided in the branch section. The reflecting section is arranged to reflect and return the shock wave back to an exhaust path and cause the shock wave to collide against the exhaust gas, thereby increasing the pressure of the exhaust gas. In accompaniment with the exhaust gas passing a divergent section of a convergent-divergent nozzle, a new shock wave propagating in a downstream direction in the exhaust path is generated, and the temperature and pressure of the exhaust gas are decreased.
