摘要： An echo canceler makes it possible to adaptably control a power of speech reception voice and to reduce distortion of a voice output from a speaker. The echo canceler has a basic structure includes a power control section controlling a power for a speech reception voice, a first filtering section removing a particular component from an output of the power control section, an echo canceling section removing echo components of a speech reception voice, which are added to a speech transmission voice, a second filtering section filtering particular components of the speech reception and transmission voices, and a state judgement section judging existences of the speech reception and transmission voices from an output of the second filtering section and controlling a power attenuation amount of the power control section based on the judgement result.

摘要： In a wind noise suppressor, a divider divides the frequency band an input sound into a first frequency band having a possibility that wind noise is included and a second frequency band having a frequency higher than a frequency of the first frequency band, a calculator calculates a probability that the input sound includes wind noise from feature parameters of a sound in the first frequency band, a suppressor suppresses wind noise included in the first frequency band in accordance with an intensity calculated from the probability, and an adder mixes and outputs the sound in the second frequency band divided by the divider and the sound in the first frequency band by which wind noise is suppressed by the suppressor.

摘要： An inspection apparatus and a semiconductor device manufacturing method using the same. The inspection apparatus is used for defect inspection, line width measurement, surface potential measurement or the like of a sample such as a wafer. In the inspection apparatus, a plurality of charged particles is delivered from a primary optical system to the sample, and secondary charged particles emitted from the sample are separated from the primary optical system and introduced through a secondary optical system to a detector. Irradiation of the charged particles is conducted while moving the sample. Irradiation spots of the charged particles are arranged by N rows along a moving direction of the sample and by M columns along a direction perpendicular thereto. Every row of the irradiation spots of the charged particles is shifted successively by a predetermined amount in a direction perpendicular to the moving direction of the sample.

摘要： A beam charge exchanging apparatus causes the charges of charged particles in a fast particle beam to be exchanged with charges of a gas or other fluid. The apparatus includes; a gas/fluid container disposed in a vacuum and having holes which allow the fast particle beam to pass through the container, a source of gas or other fluid, and a nozzle for introducing the gas into the container. The source and the nozzle are designed to introduce a high speed gas/fluid into the container so that the fast particle beam will collide with the high speed gas/fluid in the container and the charges thereof will be exchanged such that the fast particle beam is converted into a neutral particle beam. The apparatus may further include elements for detecting the quantity of neutral particles resulting from the charge exchange by measuring the quantity of generated ionized gas as an electric current.
