Sanyo Electric reported $278.6 million in profits. Its sales for the fiscal year through March rose 7.2% from the previous year to $19.6 billion, the company said. This represents a major swing from Sanyo’s loss of $439.3 million in 2006.

The company attributed its turnaround to sales of commercial air conditioners, digital cameras, rechargeable batteries and solar photovoltaic modules. A statement did not mention the wireless phone division.

The division officially became a subsidiary of Kyocera April 1 and is now called Kyocera Sanyo Telecom, officials said.

Sanyo’s phones in the United States are found on the Sprint Nextel network and include the stylish Katana series.
