marking Toyoda Gosei will focus on the development of LED product

The coefficient of linear thermal expansion of a transparent sheet that was made by adding cellulose nanofibers obtained by decomposing pulp to resin was 12.1ppm/K, Yano said. The new paper's coefficient of linear thermal expansion is smaller because pulp is made transparent without being decomposed and the orientations of its fibers are more uniform, he said.Dehydrated pulp was impregnated with acrylate resin because the refraction index of acrylate resin is 1.52-1.60, which is close to the refraction index of cellulose. Materials other than acrylate resin can be used as long as their refraction indexes are close to that of cellulose, Yano said.In general, the refraction indexes of resins change depending on temperature. But the Led high bay light transmission of the new paper does not change much even at a temperature of 90°C because the pulp prevents the thermal expansion of the resin, Yano said.In November 2011, Yano announced that he developed a technology to make a transparent sheet by using a material made by making a crab shell transparent.

Toyoda Gosei has undergone a hard time in the first half of 2011, but its revenue firmed up till second half, to 4th quarter was fully restored. And yet its Q1 revenue of 2012 also keeps the very successful performance just like Q4 last year, even the company increase profit forecast for Q2.The LED department of Toyoda Gosei had hard time when Q3 of 2011 as well. Until the new LED product line which Saga factory lead in goes into MP and the demands of Tabled PC backlighting with LED potted elements increased, Q4 revenue recovered remarkably. Besides, the revenue of this department is greatest within 7 quarters. Toyoda prospects that revenue of LED department will up to 55 billion yen in 2012.Backlight package is still the leading products of Toyoda Gosei's LED dep. up to now. But according to the company’s outlook for 2020, its LED technology is to be in the lead of worldwide lighting industry before then, marking Toyoda Gosei will focus on the development of LED product.

What's more, in this June, the company announced that its high brightness LED grain, which is 3 times brighter than common grain, could take place of mercury vapor lamps. It will be a breakthrough in LED lighting technology with successful mass production.The personnel working on existing business fields will gear their R&D toward midterm business growth. Panasonic recently focused research on OLEDs with Sony, and on flexible electronics with imec.Additionally, Panasonic is also forming a corporate strategy head office, with about 150 staffs, to oversee midterm strategies and allocate management resources, as well as develop executives and promote cash flow management.Functions other than the above will be realigned as part of a Professional Business Support Sector. Panasonic will regroup some of the related divisions into Led flood light single divisions and simplify organizations.A Group Management Team will evaluate Panasonic’s mid- and long-term strategy and important business moves, with about 10 executives involved. Various meetings will be reorganized as appropriate under this new structure.The strategy involves reviewing the mission of the corporate R&D division, transferring “themes” and personnel to their relevant business domains within Panasonic.
