    • 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.
    • 在使用常规螺杆泵的波峰焊槽中,有时会发生从排出喷嘴喷出的熔融焊料上下移动的脉动。 螺杆泵中发生脉动的原因是螺杆泵与壳体之间的间隙较宽,因此通过间隙有反向流动。 可以想到缩小间隙,但是如果间隙变窄,则如果螺杆泵变得偏心,则螺杆泵最终接触壳体。 根据本发明的波峰焊槽使得壳体底部的入口的直径小于螺杆泵的直径,使得即使螺杆泵和壳体之间的间隙较宽,也不会发生反向流动 。 通过在外壳的出口上提供向外扩张的导向壁,使流动更加稳定。

    • 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.
