Fiber fuse

40-word commentary: A phenomenon of light-induced catastrophic destruction of optical fibers for a long distance. It is initiated by spot-heating of an optical fiber delivering a few watts of light, which generats a bright spot in the core running to the light source. See also video clips, its episodes and another list of papers.

Personal informatics workbench for researchers

40-word commentary: Since the amount of information that we should deal with increases rapidly, we need an efficient and sustainable managing methodology. My practical know-how for research activities is described based on free software culture by which I've been affected since university days.

Self-archiving for outreach activities

40-word commentary: My strategic self-archiving activity and its responses are summarized. Disclosure of research-related video clips and documents in my native language is effective in attracting the attention of non-specialists and domestic readers. Then, they will follow related papers if interested.

Case study of Serendipity

40-word commentary: A practicing researcher's serendipitous experience. The two lessons learnt are: (1) have a sensible mind to grap chances throughout your research activities and (2) impress your audience and readers with your interesting work. Then heaven helps you with miraculous success.

Preparation of LaTeX slides

40-word commentary: Application of Rule of Three to whole slides makes them impressive to the audience. The labor of their preparation is fairly reduced through LaTeX and scripting languages. The author's know-how and the benefit gained are introduced.

Optical fuse

40-word commentary: A device inserted in an optical fiber circuit which breaks in responce to excess incident light. As is the case of fuse in electric apparatus, it protects optical systems from accidents. My device is made of a low-melting glass and breaks down thermaly. See also video clips

Fiber splicing via soft glass

40-word commentary: A technique for making optical fuse described above. Small amount of captured glass melt between two ends of silica glass optical fibers is quenched to form the device structure. It is applicable even for the melt with poor thermal stability. See also video clips

Virtual sample library

40-word commentary: As a result of applying multiple evaluation methods on a group of samples, the data obtained becomes multi-dimensional. The larger its size is, the harder its analysis becomes. A concept of virtual data container is proposed to handle it intuitively.
