40results about How to "Closer in characteristic" patented technology

In order to analyze an information signal, a significant short-time spectrum is extracted from the information signal, the means for extracting being configured to extract such short-time spectra which come closer to a specific characteristic than other short-time spectra of the information signal. The short-time spectra extracted are then decomposed into component signals using ICA analysis, a component signal spectrum representing a profile spectrum of a tone source which generates a tone corresponding to the characteristic sought for. From a sequence of short-time spectra of the information signal and from the profile spectra determined, an amplitude envelope is eventually calculated for each profile spectrum, the amplitude envelope indicating how a profile spectrum of a tone source all in all changes over time. The profile spectra and all the amplitude envelopes associated therewith provide a description of the information signal which may be evaluated further, for example for transcription purposes in the case of a music signal.

Conventionally, VF and IR characteristics of a Schottky barrier diode are in a tradeoff relation and there is a problem in that an increase in a leak current is unavoidable in order to realize a reduction in VF. To solve the problem, p type semiconductor regions of a pillar shape reaching an n+ type semiconductor substrate are provided in an n− type semiconductor layer. When a reverse voltage is applied, a depletion layer expanding in a substrate horizontal direction from the p type semiconductor regions fills the n− type semiconductor layer. Thus, it is possible to prevent the leak current generated on a Schottky junction interface from leaking to a cathode side. Since an impurity concentration of the n− type semiconductor layer can be increased to a degree at which the depletion layer expanding from the p type semiconductor regions adjacent to each other can be pinched off, it is possible to realize a reduction in VF and it is possible to secure a predetermined breakdown voltage if only the depletion layer is pinched off.
