An audio data processor (120) performs a decoding process and a compression (encoding) process with respect to audio data in units of frames each containing a predetermined number of samples. The resultant encoded data is temporarily accumulated in an encoded data buffer (110). A song boundary detector (106) detects a frame boundary which should be used as a song boundary based on song position information corresponding to the audio data and feature information output from a feature extraction signal processor (107). A frame boundary divider (111) modifies the encoded data accumulated in the encoded data buffer so that a frame boundary of the encoded data matches the detected frame boundary.

A polishing composition of the present invention, which is used in precision polishing the surface of a wafer for semiconductor devices, remarkably reduces haze that occurs on the surface of the wafer. The polishing composition includes silicon dioxide, an alkaline compound, a water-soluble polymer, and water. The silicon dioxide is colloidal silica or fumed silica. The average primary particle diameter DSA of the colloidal silica is from 5 to 30 nm, and the average secondary particle diameter DN4 of the colloidal silica is from 5 to 120 nm. The average primary particle diameter DSA of the fumed silica is from 5 to 30 nm, and the average secondary particle diameter DN4 of the fumed silica is from 5 to 200 nm.

The present invention provides a technique enabling the amount of time required to evaluate the light fastness of a liquid crystal panel to be shortened. A method of testing the light fastness of a liquid crystal panel comprising a pair of substrates and a liquid crystal layer interposed between the substrates comprises the steps of: irradiating a test subject area of the liquid crystal panel with a laser beam, with at least one of the wavelength, the irradiation energy, and the irradiation duration of the laser beam set as a variable parameter; irradiating the liquid crystal panel with an observation beam and detecting the condition of the observation beam after passing through the liquid crystal panel; and evaluating the light fastness of the liquid crystal panel on the basis of a difference in the condition of the observation beam corresponding to the setting of the variable parameter of the laser beam.
