    摘要: Disclosed is an audio system including a group of loudspeakers that form a sound field by delivering into a single space sound signals passed through respective ones of a plurality of sound signal channels. This audio system is comprised of two characteristic-variable equalizers that are cascaded to each other to constitute a part of the sound signal channels; a sound field characteristics detecting part for supplying test signals through the sound signal channels and detecting sound pressure in the sound field and thereby obtaining a sound pressure signal; and a characteristics adjusting part for adjusting, based on the sound pressure signal, equalizing characteristics of the characteristic-variable equalizers individually and with respect to each of the sound signal channels. The sound field characteristics detecting part selectively generates test signals of different bands. The characteristics adjusting part adjusts equalizing characteristics of either one of the two characteristic-variable equalizers according to the band of the test signal.

    摘要: An iodide compound is adsorbed and removed from an organic acid containing the iodide compound as an impurity by passing the organic acid through a packed bed of a cation-exchange resin having silver ion carried thereon at 50° C. or lower. The cation-exchange resin is a macroporous-type resin with an average particle size of 0.3 to 0.6 mm and an average pore size of 15 to 28 nm, and silver ion substitutes for 40 to 60% of the active site.

    摘要: A digital watermark embedding method of the present invention includes: a step of sequentially obtaining each frame image of the moving image data and frame display time; a step of generating a watermark pattern using watermark information, the frame display time and watermark pattern switching information; a step of superimposing the watermark pattern onto the frame image, and combining watermark embedded frame images obtained by sequentially repeating the processes to generate watermark embedded moving image data. A digital watermark detection method includes a step of sequentially obtaining a frame image; a step of generating a difference image between the currently obtained frame image and a previously obtained frame image; and a step of performing digital watermark detection from the difference image to output digital watermark detection status, and when digital watermark detection process is continued, obtaining a new frame again to repeat the above processes.
