Doped ceria (CeO2) compounds are fluorite-type oxides that show oxide ionic conductivity higher than yttria-stabilized zirconia in oxidizing atmosphere. As a consequence of this, considerable interest has been shown in application of these materials for "low" (500deg-650degC) temperature operation of solid oxide fuel cells (SOFCs). To improve the conductivity in dysprosium (Dy) doped CeO2 , sinterability nanopowders were synthesized via carbonate coprecipitation method. The dense sintered bodies were fabricated using a combined method of spark plasma sintering (SPS) and conventional sintering (CS)

The development of the thermal stress free waterproof pan for prefabricated bathroom, thermo floor was described in this paper. For development, the evaluation methods of cold sensitive index was discussed and defined as an index of discomfort when feet touched with surface of the pan. Ceramic balloon filler was used for reducing the thermal conductivity of the material. As a physiological evaluation, the change of temperature of feet bottom and blood pressure in touching thermo floor were confirmed to be lower than in touching existing pan. So, thermo floor is effective for decreasing the thermal stress

Recently UNEP (United Nations Environment Programme) has advocated an action plan focused on new systems of production and consumption as a final step towards sustainable society, after its decades of work on cleaner production. To achieve the goal, however, so-called "rebound effects" require serious attention, for such effects might offset the environmental benefits of eco-efficient products. In this study, it was tried to quantitatively clarify the effect based on the method that have developed, i.e. environmental household accounts using input-output table. This study first extend the analysis using 1985-90-95 input output table in "linked" form, and then decompose the change in the induced CO2 emission in the decade into three parts; the effect of the change in consumption structure, the effect of the income increase, and the effect of the technological change. Through the analysis, the changes that are attributable to the rebound effect are identified, and their causes are clarified. The present method, together with the results, provides a base for the design plan for the construction of sustainable consumption society

The article describes an intelligent biomass-plastic with a rewritable shape memory, which has advantages over petroleum-based plastics and will expand the use of biomass-plastics. A thermo-reversible bond between furan and maleimide was introduced into the molecular structure of polylactic acid (PLA). The bond acts like a thermo-switch, providing two normally incompatible characteristics, that is shape memory and recycling. When the thermo-switch is turned on at low temperature, the biomass-plastic acts complete shape memory. When the thermo-switch is turned off at high temperature for molding, the memory is easily erased, and the plastic becomes recyclable (i.e. rewritable)

This paper analyses essential background of an recently emerging trend of eco-design; global eco-product policies (legislations), market competition and eco-supply-chain management. In the light of this trend, an on-going project of international standardization is described, by highlighting its basic strategy; "load-sharing with data-sharing", as well as its expected contributions to worldwide harmonization and solutions for technical/information gaps to overcome.

Design For Disassembly (DFD) is the effective process to improve recyclability of the electric and electronic equipment. The Design For Disassembly (DFD) tool has been developed that calculates recycling cost and recycling indices easily. These recycling parameters should be decided and improved by the common process at the recycling plants as much as possible. The dehumidifier unit is dismantled and these parameters are calculated, and this tool improved the dismantling process. It is confirmed that DFD is very effective to review and improve the product recycling efficiency

"SATIS", a compact and full-automatic toilet, is a 21st century eco-product that increases the product's value and reduces the burden on the global environment at the same time. From the ecological viewpoints, our corporate vision to develop new products is to improve the product's value for users and to reduce the impact on the global environment. INAX is actively seeking to implement the "Manufacture, Use, and Return" cycle. "SATIS" offers many advanced functions to users. In addition, we have succeeded to reduce the environmental burden by applying new solutions at each phase through "SATIS" development process.

Recently energy saving electric household appliances are required. In electric household appliances, a refrigerator occupies 17% of electricity consumption at home. Because a compressor motor was driven low speed mostly in a refrigerator, the energy conservation is able to achieve by improvement of motor driving efficiency in low speed drive. In order to achieve this purpose, we developed the brushless DC motor and the sine wave inverter for the refrigerator. In this paper, we show new motor drive technology for the compressor motor in high and low speed drive in order to achieve more improvement of total driving efficiency.

Sago barks are prospectus for bio-composite in technical and for resource availability consideration. The area under sago cultivation in wild and semi-wild condition is estimated at 19,720 hectares. Today, the total area planted with sago is over 28,000 hectares. Sago (metroxylon spp.) bark is waste material in the sago production industries. The locals use the barks of the trunk as timber fuel, temporary walls, ceilings and fences. At present, sago barks are processed through bio-composite method to produce sago plywood and particleboards, which have potential in building material. However the process does not utilize the natural feature and the beauty surface of the sago bark. The aim is to create products that involve recycling waste sago barks into value added products that is good in appearance, performance and reliability. Through the exploitation of sago bark waste, a promising materials resources to be used for global environmental conservation and sustainable development

Many eco-design methodologies are available at present for physical products in industries. Yet, missing is another piece of technology; a way of balancing the value and cost of multiple stakeholders related in a service. This is critical because a service with an excessive load on one of the stakeholders does not work as a whole. For the sake of this, the authors propose a model named MVC (Model for Balancing Value and Costs), which is a fundamental model to design services with an appropriate balance. In MVC, a flow model from Service Engineering serves as a basis. In addition, presented are a preliminary description of the model with associated evaluation functions and operations in design
