Provided is an information-providing system whereby a variety of information can be provided using a sound to a portable terminal device used by a user. The information-providing system includes a sound output device outputting, as a sound wave, identifying information modulated into a sound signal, an identifying-information resolution server, connected to an information-communication network, for identifying, based on the identifying information, address information for accessing a content server connected to an information-communication network; and a portable terminal device including a sound receiving section for receiving the sound wave outputted by the sound-emitting device, a demodulating section for demodulating the identifying information from the received sound wave, a resolution section for sending the demodulated identifying information to the identifying-information resolution server and acquiring the address information, and an accessing section for accessing the content server using the acquired address information.

摘要:
A pseudo noise superimposing unit superimposes a pseudo noise (M-sequence) to an audio signal picked up by a microphone and outputs the superimposed signal to an amplifying system. An calculating unit calculates a correlation value between the audio signal picked up by the microphone and the pseudo noise. The calculating unit estimates a gain of a closed loop based on the correlation value. A gain control unit suppresses a gain of the audio signal based on the estimated gain of the closed loop.

A solar cell includes a p-n junction formed by joining a p-type semiconductor and an n-type semiconductor. The p-type semiconductor is a chalcopyrite compound semiconductor with a band gap of 1.5 eV or more within which an intermediate level exists with a half bandwidth of 0.05 eV or more. The intermediate level is different from an impurity level. The chalcopyrite compound semiconductor includes a first element having first electronegativity of 1.9 or more in Pauling units, the first element occupying a lattice site of the semiconductor. A portion of the first element is substituted with a second element having second electronegativity different from the first electronegativity, the second element being a congeneric element of the first element. The intermediate level is created by substituting the first element with the second element.

An electronic musical instrument and a portable terminal are connected to a wireless LAN. The wireless LAN is connected to an Internet via a router. A distribution server residing on the Internet is a server which provides Internet services. A pairing between the electronic musical instrument and the portable terminal is established to conduct Internet communications in a pair. Processes from accessing the distribution server to specifying a desired service are performed by use of the portable terminal. The distribution server distributes data corresponding to the service specified by the portable terminal to the electronic musical instrument. A user is thus allowed to use the desired service on the electronic musical instrument.,
