Latest Patents

Nigorikawa holds a patent for a "Device for detecting the position of crystallization interface." This device is designed for use in a monocrystal producing apparatus based on the FZ method. It effectively detects the crystallization interface between a melt and a monocrystalline rod, even when the luminous line of the crystallization interface is partly curved downward. The device samples a series of luminance signals along a sensing line intersecting the crystallization interface. It outputs a series of sampled luminance signals, determines a reference level, and discriminates the crystallization interface when one of the sampled signals exceeds this reference level. This innovation is crucial for improving the accuracy and efficiency of monocrystal production.
