Abstract: PURPOSE:To eliminate noise due to changeover between an audio part and a musical sound part by mixing two signals in stereo transmission and a differential signal and outputting the mixed signals so that the mixture ratio is changed complimentarily in response to the lapse of time from a point of time when the audio part and the musical sound part of an audio signal are switched. CONSTITUTION:A differential signal generating circuit 15 outputs a difference (c) between two signals a, b in stereo transmission in audio signals of plural channels. A mixing circuit 21 mixes the two signals a, b and the output (c) from the differential signal generating circuit 15 and outputs the result so that the mixture ratio is changed complimentarily in response to the lapse of time from a point of time of changeover of the result of decision outputted from a decision means 19 deciding the audio part and the musical sound part of an audio signal are switched. Then a sound field effect circuit 17 provides a sound field effect to an output from the mixing circuit 21. Then the mixture rate where the difference signal (c) is mixed in L, R signals changes gradually from a point of time of the changeover of the audio part and the musical sound part thereby preventing generation of noise.

IPC: G01B11/24
Filed: 1985-04-19
Abstract: PURPOSE:To enable detection at high accuracy by constituting the nozzle multiply to constitute pressure wall of fluid jetted from outside nozzle around fluid jetted from inside nozzle. CONSTITUTION:A nozzle 5 is constituted doubly of an inner tube 6 and an outer tube 7. Accordingly, flow of air jetted from the opening end of the inner tube 6 is sorrounded by a pressure wall constituted by flow of air jetted from the opening end of the outer tube 7. When a space between the opening end of the nozzle 5 and the plane of a wafer 2 becomes more than a specified value, outflow of air to outside starts from a space A in the inner tube 6 through the pressure wall. Consequently, when a safety space to prevent damage of the wafer 2 is provided between the opening of the nozzle 5 and the plane of the wafer 2 caused by contact of the two, variation of pressure in the space A detected by an air pressure detecting section 12 for specified displacement of the plane of the wafer 2 in the direction of optic axis of a microscope section 3 becomes large. Thus, sensitivity of detection of displacement in the direction of optic axis of the microscope section 3 can be increased.
