照明用白色有机EL元器件的开发趋势 笹部久宏,城户淳二
<Abstract> 1993年世界首创的白色有机EL元器件,当时的电功率只有小于1 lm W–1,寿命还不到一天,就像夏天的夜空中飘荡的萤火虫一样微弱。从那以后,已经有20年过去了,其性能有了显著的提高,有望在一般照明领域中得到广泛的利用。本文介绍了这些白色有机EL元器件的最新研发进展。

有机EL照明的现状和今后展望 岩崎利彦
<Abstract> We report recent progress and future prospects of OLED lighting based on KONICA MINOLTA’s development activities. We have been working on two approaches, vacuum thermal evaporation and solution processing, to make white OLED lighting using proprietary blue phosphorescent technology. In 2011, the world's first all-phosphorescent OLED lighting panel was brought into market, which has been the best candidate technology to achieve the attractive performance as the lighting application, especially considering efficacy.
On the other hand, we demonstrated the feasibility of the solution-processed OLED technology by showing unique OLED lighting prototype fabricated by the roll-to-roll R&D line in 2010. Though solution-processed OLED has potential for high productivity and large-scale fabrication capability, it is widely believed that the device performances fabricated by the solution process are inferior to that of vacuum process so far.
In this paper, recent OLED performance using our new blue phosphorescent material by vacuum process and the overview of solution processed OLED development are discussed.

高导热聚碳酸酯复合材料 井野庆一郎
<Abstract> Polymer materials have lower thermal conductivity than metal materials and ceramics. Therefore, polymer materials are used as thermal insulations. Polymer materials are used for various products because of excellent injection moldability. These days, electronic devices are increasingly using highly efficient semiconductors. Calorific value of an electronic device increases with the miniaturization of semiconductors, and its high integration. To maintain the performance of an electronic device, a sufficient cooling system is required. For test results, the 6 mm interval of the radiating fin - fin is desirable. Thermally conductive polycarbonate composite has a thermal conductivity of 4.0 - 11.0 W/m・K. The effective range that
performs heat conduction is 25 mm at the maximum, 25 mm height of a radiating fin is desirable. Around 3 mm thickness of a radiating fin is desirable, and around 5 mm thickness of the base cast by the side of a LED module is desirable to secure a heat current way, and for injection moldability.

LED反射膜用耐热性聚酰胺树脂 田村兴造
<Abstract> Genestar™, a PA9T-based heat resistant polyamide, is widely used as a reflector for LED packages due to its good mold-ability, heat resistance, and light resistance. We believe Genestar™ and its new polymer, with superior resistance against heat and light, will help LED to be a standard light source for lighting applications.

由草和木制备出聚合物原料 原 亨和
<Abstract> Emerging trends in chemical industry are prompting sustainable production of useful chemicals, including polymers and new materials, from renewable cellulosic biomass. This requires at least two chemical processes: hydrolysis of cellulosic biomass into mono saccharides and tranformations of monosaccharides into useful chemicals. However, efficient transformations of cellulosic biomass and monosaccharides are no easy task. Here, we demonstrate efficient cellulosic biomass transformation into heterocyclic aldehydes by novel heterogeneous catalysts.
