Abstract: When reflection light, reflected from a measurement target that has been irradiated with measurement light in such a manner to scan the measurement target, and reference light are combined in each wavelength sweep, interference light is detected as interference signals. When a thinning region in which the interference signals obtained by detecting the interference light in each wavelength sweep are thinned so that the interference signals that are used to produce the tomographic image remain is set, thinning is performed on the plurality of interference signals in the thinning region. Light intensity information about the measurement target in the thinning region is obtained, based on the interference signals for the respective wavelength sweeps, the interference signals remaining after thinning. The tomographic image in the thinning region is produced based on the obtained light intensity information.

Abstract: In a wave soldering tank using a conventional screw pump, pulsation sometimes occurred in which molten solder spouting from the discharge nozzle moved up and down. The cause of the occurrence of the pulsation in a screw pump was that the gap between the screw pump and the casing was wide, so there was reverse flow through the gap. It is conceivable to narrow the gap, but if the gap is made narrow, the screw pump ends up contacting the casing if the screw pump becomes eccentric. A wave soldering tank according to the present invention makes the diameter of the inlet in the bottom of the casing smaller than the diameter of the screw pump so that reverse flow does not take place even if the gap between the screw pump and the casing is wide. Flow is made more stable by providing outwardly flaring guide walls on the outlet of the casing.

Abstract: A discharge device in a substance modifying device is provided with a positive electrode in linear or needle form and a negative electrode in plane form. Thus, substances having a nanostructure are made to contact an active species generated through streamer discharge, which is discharge between the positive and negative electrodes, where discharge between certain points of the positive electrode and a number of points on the negative electrode occurs stably and approximately simultaneously, and is diffused from between the positive and negative electrodes, so that the nanostructure is eliminated. The nanostructure is eliminated in this manner, and thus, the bioinvasive response due to the nanostructure of substances is reduced.
