Corporate
Profile

[Company strength]
We apply the technologies we have built up in 50 years of operation since our establishment to manufacture various products. These include compact communications device transformers, large three-phase transformers, and power supply unit assembly. Our plant in Tianjin, China was set up 20 years ago. It maintains consistent quality, following its management policy of providing high-mix low volume production. 


[Business description]
Our company designs, manufactures, and sells various transformers such as power transformers, high-efficiency reactors, and power supply units. All our products from special transformers to high-efficiency reactors can be designed and manufactured at our own two plants, in Nagano Prefecture and Tianjin City, China. Design is currently conducted at our site in Japan, and mass production is handled by our plant in China to realize high quality at low cost. 


[Industry]
Manufacturing


[Representative's message]
Our company, is known for its one-by-one production of transformers. We were initially established by Koichi Noguchi in Suginami Ward, Tokyo as an audio equipment power supply manufacturer, and we later shifted to the transformer manufacturing and distribution business. Our business has steadily grown over the years since then, making use of two manufacturing sites, in Nagano Prefecture and Tianjin City. Other design and development projects we are currently pursuing include medical devices, measuring instruments, and other special-purpose articles. 


[Company structure for market development/overseas expansion]
We take pride in our technological capabilities, and especially those for developing 0.5 to 15 kVA transformers and high-efficiency reactors. We also provide optimal air gap formation processing for ferrite cores used in medical transformers. Our latest product is a new transformer where an uncut iron core is wound onto a newly developed coil bobbin. This product was developed from an SC transformer that is already popular. We were able to develop the coil bobbin and iron core winding device as a result of further R&D. These two items helped us improve productivity in winding, insulation, and iron core winding, and led to consistent quality while significantly reducing the manufacturing cost.
