摘要： As a negative electrode active material that enables steady production of batteries with excellent low-temperature performance, provided is a composite carbon comprising a low-crystalline carbon material at least partially on surfaces of particles of a high-crystalline carbonaceous substance. The negative electrode active material has a tapped density of 0.9 g/cm3 or smaller and a distribution of R values equal to or rater than 0.2, D2, of 20% or greater. Here, the R value is a ratio of the D-band intensity ID to the G-band intensity IG, ID/IG, in a 532 nm wavelength Raman spectrum of the negative active material. When a sample of the negative electrode active material is subjected to n (n≧20) times of microscopic Raman analysis at a wavelength of 532 nm and m is the number of times where the R value in the resulting Raman spectrum is equal to or greater than 0.2, the DR≧0.2 is a percentage of m to n.

摘要： A sound signal switchover means capable of preventing pop noise sound in an audio system from being generated is down-sized, and a time constant of a time constant unit for the changeover of the sound signals can be varied, thereby enabling the switchover to be implemented with greater smoothness. A sound signal selection means (12) having a plurality of switches (SW 1a′ to SW 2b′) for switching over the sound signal to the sound signal having the different output level is provided between a sound input source, and a sound output means. When switching over the sound signal to the sound signal having the different output level, the sound signals before and after the switchover coexist and the switchover is implemented at that point in time. A time constant unit (8) is made up of a SCF built in an IC, and the time constant τ can be controlled to be freely adjusted by a clock signal Fclk obtained by dividing a reference signal generated in a VCO (6) by a variable frequency dividing rate.
