Conventional optical see-through displays are not capable of correctly presenting the mutual occlusion of real and virtual environments, since the synthetic objects always appear as translucent ghosts floating in front of the real scene. We have been developing an optical see-through display that is capable of such mutual occlusion. Our display, named ELMO,(More)
In a mixed reality system, mutual occlusion of real and virtual environments enhances the user’s feeling that virtual objects truly exist in the real world. However, conventional optical see-through displays cannot present mutual occlusion correctly since the synthetic objects always appear as semitransparent ghosts floating in front of the real scene.

Ionic liquids are room-temperature molten salts, composed mostly of organic ions that may undergo almost unlimited structural variations. This review covers the newest aspects of ionic liquids in applications where their ion conductivity is exploited; as electrochemical solvents for metal/semiconductor electrodeposition, and as batteries and fuel cells(More)
We successfully prepared low viscosity, polar, and halogen-free ionic liquids as potential solvents for a wide range of polysaccharides. A series of 1,3-dialkylimidazolium formates were produced as liquids having strong hydrogen bond acceptability. These formates had significantly lower viscosity than previously reported polar ionic liquids, in particular(More)
We first succeeded in synthesizing ionic liquids from 20 natural amino acids. Amino acid ionic liquids dissolved native amino acids, despite water-free conditions. Furthermore, these ionic liquids are soluble in various organic solvents, such as chloroform. Effects of acidity, hydrogen bonding ability, and steric factors on the properties of these ionic(More)

Water was originally inimical to ionic liquids (ILs) especially in the analysis of their detailed properties. Various data on the properties of ILs indicate that there are two ways to design functions of ionic liquids. The first is to change the structure of component ions, to provide "task-specific ILs". The second is to mix ILs with other components, such(More)
In this paper, an insect biofuel cell (BFC) using trehalose included in insect hemolymph was developed. The insect BFC is based on trehalase and glucose oxidase (GOD) reaction systems which oxidize β-glucose obtained by hydrolyzing trehalose. First, we confirmed by LC-MS that a sufficient amount of trehalose was present in the cockroach hemolymph (CHL). The(More)
A polymerised ionic liquid (poly(IL)) having suitable hydrophobicity undergoes a strongly temperature-sensitive LCST-type phase transition with pure water and also with aqueous salt solution, and the resulting hydrated poly(IL) further undergoes a sharp and reversible liquid-to-gel transition at ambient temperatures.
