According to one embodiment, a sound processor includes a creating module, a filter, and a combining module. The creating module creates a plurality of first acoustic models based on a frequency characteristic that represents an acoustic property of an object to be measured. The first acoustic models are modeled with respect to resonance properties that vary depending on frequency bands. The filter extracts frequency components in the frequency bands from the respective first acoustic models. The combining module combines the frequency components extracted from the first acoustic models to create a second acoustic model.

According to one embodiment, in switching of a channel to a digital broadcasting tuner, when the switched channel is selected by any of a plurality of one-segment broadcasting tuners, an output of an one-segment data processing part, which applies demodulation processing and decode processing to an output of the one-segment broadcasting tuner selecting a broadcasting signal of the switched channel, is selected. When a digital data processing part terminates the demodulation processing and the decode processing to the broadcasting signal selected by the digital broadcasting tuner, the output is switched such that an output of the digital data processing part is selected and output.

In a bookbinding machine, an image forming apparatus, a prebinding apparatus and a bookbinding apparatus are coupled on line in this order. In the prebinding apparatus, a sheet aligning section, a slitting section which cuts off margins at both side portions of a sheet of paper, a cutting section which cuts off top and bottom margins, and a creasing section are arranged in this order. The prebinding apparatus is provided with a control section which sorts out supplied sheets of paper into those which need an SCC step and those which do not, and performs the SCC step only on the sheets of paper that need the SCC step.

A semiconductor laser element is fixed onto a submount by forming a metallic thin film at a region on a surface of a p-side electrode of the semiconductor laser element. A periphery of the thin metallic thin film is recessed from a periphery of the p-side electrode by a predetermined width. The metallic thin film is thermally processed together with the p-side electrode for increasing a size of the grains and connected through a solder layer to the submount. Parts of the p-side electrode and the submount, the metallic thin film and the solder layer include Au for improving a cushion function of the semiconductor laser device.

In a semiconductor pumping light source module according to the present invention, a fiber grating (FBG) is disposed, outside a ferrule, in an optical fiber that is inside a protective tube to define a cavity between the FBG and the semiconductor laser device. The FBG is disposed, outside the ferrule, in the optical fiber that is inside the protective tube inside a protective boot. The FBG is disposed on the optical fiber at a portion where no adhesive exists inside the protective tube. The semiconductor pumping light source module is used as a pumping light source of the optical amplifier. The semiconductor pumping light source is also used as the pumping light source of a Raman amplifier.

According to one embodiment, a sound corrector includes a signal outputter, a response signal, a frequency specifier, a coefficient specifier, a filter, and an outputter. The signal outputter outputs a measurement signal to measure acoustical properties of an object to be measured. The response signal receiver receives a response signal from the object in response to the measurement signal. The frequency specifier specifies a resonant frequency at a resonance peak from the response signal. The coefficient specifier specifies a correction coefficient of a correction filter for reducing the resonant frequency based on the specified resonant frequency. The filter performs filtering on a signal to be output to the object using the correction filter with the correction coefficient. The outputter outputs the signal having undergone the filtering to the object.
