The world of the technology of the quartz crystal is transforming toward the new generation, just like a large liver stream flowing into the ocean. We are questioning to ourselves. "What to do now to show our capability in the future? "What is necessary to be a van of the new era?". Of course, it is natural for us to comply with an individual requirement from customer. However, we are believing that we need continuing effort to improve our product and service. We further believes that our progress will not be possible without "challenging to higher goal", "thinking from customer's view", and "repeated consideration and trial". We look forward to being a company that appeals for our existence as "Only One".
