On January 3, 2008, the US International Trade Commission (ITC) decided to designate Paul J. Luckern as an administrative judge to conduct a hearing investigation on the application for an injunction issued by Seoul Semiconductor on December 4, 2007. Nichia Corp., a Japanese LED manufacturer, investigates short-wavelength semiconductor lasers (built into consumer electronics such as high-definition DVD players).
The lawsuit between Seoul Semiconductor and Nichia's two major LED manufacturers has been delayed for several years. Nichia was announced on December 28, 2007, and has filed a lawsuit against Seoul Semiconductors in the Central District Court of Seoul, South Korea, in addition to claiming damages of 500 million won, and demanding that the other party be responsible for the restoration of necessary measures related to reputation.
Seoul Semiconductor announced in November 2007 that the Northern California District Court had pronounced that only one of the four products previously indicted by the company was infringed. According to the press release, the infringing product was confirmed to be "side view LED 902" for mobile phone backlights sold in the United States, and the product has been discontinued.
Seoul Semiconductor Introduction
Seoul Semiconductor is a worldwide LED lighting supplier and has been selected as the most promising company in Asia by two internationally renowned magazines, Forbes and Business Week. Seoul Semiconductor's Acriche environmental lighting technology has recently been selected as the "Best Product of 2006" by the European authoritative electronic magazine "Elektronik". Seoul Semiconductor's main business is the production of full-line LED assembly and custom module products, including AC-driven semiconductor light source products such as: Acriche, high-brightness high-power LED, side-light LED, top-light LED, slice LED, plug-in LED and piranha (Super light) LED, etc. Products have been widely used in general lighting, display lighting, mobile phone backlights, televisions, laptops, automotive lighting, household items and traffic signals. Seoul Semiconductor’s total sales in 2006 reached 200 million US dollars. As of June 30, 2007, Seoul Semiconductor had a total of 1,251 patents and 100 exclusive licenses, a total of 18 branches, including three overseas companies, and around 90 sales points around the world.

The single groove blanking process of motor blanking is a kind of blanking process relative to double blanking. Motor fixed, Rotor Core punching using single groove punching process, its mold design, manufacturing are relatively simple, suitable for small batch, variety of production, has the characteristics of low cost, fast change. With the development of advanced punching machine, production efficiency continues to improve, the single punching process is also developing rapidly. For the large motor, because of the cost of the duplex die and the equipment capacity, the single groove is also used. Another advantage of single groove punching is the consistency of groove size. Compound die is the same punch, stator or rotor groove completed at one time. How many slots correspond to the same number of punches, punch size to achieve complete has always been some difficulties: single slot punching is by the same punch to complete all the slots, groove consistency is better.
Stator and rotor laminations are an important part of motors and generators. For large-size and small-batch punching sheets, we usually use the notching method to produce them. The advantages of notching are that the cost of the notching die is low and the production cycle of the notching die is short. It is suitable for producing large size laminations, usually the outer diameter is from 500mm-1250mm. The slot size is more accurate than Laser Cutting.
