摘要:
An audio signal amplitude adjusting device and method that can always adjust the amplitude of an input audio signal to such a level as to be easy to hear with making it follow each shift in the level of the input audio signal, thus preventing the occurrence of the sense of aural discomfort and an interruption of a voice. The gain of a variable attenuator for adjusting the amplitude of the audio signal is controlled in various ways. When a momentary large noise sound is contained in the audio signal, the gain reduced state invoked to suppress the effect of the noise sound is detected, and thereafter if the amplitude of the audio signal has become smaller than the reference level due to the noise sound ending, the gain is increased each period that is shortest among the periods of control employed.

摘要:
A pulverized thermoplastic resin product such as a pulverized thermoplastic product containing a black pigment, a mixture of a pulverized thermoplastic product containing a colored pigment and a pulverized thermoplastic product containing a colored pigment, or a pulverized thermoplastic product containing two or more different colored pigments can be converted into colored reclaimed resin particles by a method comprising the steps of mixing the pulverized resin product with a white pigment and a black pigment, melting the resulting mixture, and converting the molten mixture into solid particles. The colored reclaimed resin products can be utilized in various field.
