MIJINKO SOKEN LLC (Daphnia Innovation Lab) @ mijinko.biz is a tiny firm challenging to resolve social problems and create new values.
We have developed various seeds for solution of critical problems the society is facing and creation of new values ever exist in the world.
Meaning of MIJINKO SOKEN:
MIJINKO is a Japanese word meaning daphnia, cute plankton, popular and beloved in Japan. Even being a tiny creature, of which the DNA has the largest information among all creatures ever found and checked. SOKEN means general reserch institute. Our corporate name MIJINKO SOKEN implies wide range of specialty condensed in a tiny minimal entity.

Industrial
We are also engaged in technological development, devising and designing in industrial fields, as well as arhitecture. Among those seeds, ones for general consumers are introduced below.
Trolley bags and suitcases based on an innovative idea and design with L-shaped handle that enables you to easily carry it and avoid collision of it with othersThose seeds can be lisenced for your production and sales.
Disaster and Pandemic
We cope with solving inpending social problems by proposing technical solutions.
Though our seeds are available basically by lisencing, some solutions are offered for free as output of our probono activity. For specific, inquire us.
Technological Proposals for COVID-19 Prevention
We propose airborne infection prevention solutions on two categolies. One is air conditioning and ventilation, and the other is face masks.
Even though COVID-19 has been almost settled, we need to prepare for outbreaks of epidemics. Hence we herewith left relating articles and peges for infection prevention. We believe our solutions are quite effective to diminish the risks of airborne infection of those.
Air/fluid steralization system taking advantage of UV light in a long optical path
The respirator structure realizes low permiation resistance for breathing by expanding filtering area of the existing resprators such as N95-N100. The structure can also realize ultra-high performance using ULPA.
A respirator taking advantage of air pressure fluctuation due to the wearer's breath to generate static electricity, which charges the filter and adsorbs particles. The mechanism can also be applicable to air filters.
An air filter for adsorbing virus with charged potential of static electricity generated due to the vibration of Karman vortices in the airflow passing through it.
Airborne infection prevention method by AIR FLOW ARRANGEMENT not depending on ventilation air volume.
Raised floor system enables compatibility of ventilation, air conditioning and infection prevention for separated compartments of sheltersSee the page on disaster prevention
Disaster Prevention and Mitigation
We have conceived and proposed various technical solutions for disaster prevention and mitigation, mainly on rescue and evacuation methods from tsunamis and floods.
Device to rescue drawn people in the tsunami water by lifting them up to the water surface taking advantage of tsunami water flow. At the same time the device constitute refuge from tsunami.(PATENTED)
Normally it functions as an observation platform or a management facility of a harbor, but at the time of a tsunami or other disasters, it becomes a evacuation destination and simultaneously functions as a base for rescue activities from land, sea and sky.
Combining WALL OPENING SYSTEM and TSUNAMI RESCUE FACILITIES for building walls provide the building with special functions: Enabling the building to be a refuge and to save people inside it upon flooded.
Structural system that can prevent from receiving a huge dynamic load from a water stream by a tsunami or a flood.If applied to the walls of buildings, the walls can be flown off or rotated to open to avoid building collapse.
Condominium that can function as a TSUNAMI RESCUE FACILITIES by releasing walls and rotating fences that are applied with STRUCTURAL SUSPENSION SYSTEM / WALL OPENING SYSTEM FOR PARRYING WATER FLOW" when flooded.
Last resort for handicapped people to evacuate
Proposal and technical consideration of tsunami/flood evacuation car that can float by the buoyancy of the air bag and insulation material filled in the gap space. 
The indicators guide the evacuees to the best evacuation destination with their light colors, etc. seeable from where he or she is.
Combination facilities of TSUNAMI RESCUE FACILITIES and sea walls with flap gates brings benefits: Flooded water can be drained safely from the region. It can be applied not only to sea walls but to river banks.
It filters long timber etc, that share huge volume of debris due to demolition of wooden houses. It can function as TSUNAMI RESCUE FACILITIES as well by inducing the caught debris along its slits to incline to lift up drifted people.
Evacuation lifting method for elderly and handicapped people: Utilizing the body weight of the helper. I t functions without electricity.
Disaster prevention planning deplayingTsunami Rescue Facilities to constitute life safety nets
Structure mechanism that can be applied to disaster prevention related facilities, etc. which can be stored flat in road or ground. In the event of a tsunami or flood, it rises by harnessing the energy of the water stream.
Evacuation lifting method for elderly and handicapped people: Utilizing counter weight. It functions without electricity.
Proposal of extinguishing method for tsunami fire due to spillage of flammable liquid: extinguishing/preventing fire by covorring outflown flammable liquid with nonflammable liquid in lighter specific gravity than the flammable liquid or foamed effervescent liquid.See the page on disaster prevention
Environment and Social
Our also propose technical solutions on environmental and social.
Caution on unnoted impact due to thermal load for car interior for energy saving, reduction of CO2 and environmental load and CO2. Mitigation measures realize nomad life including car tele-work and indivisual evacuation preventing COVID-19 infection. (Sorry, English page is in preparation)
Suggestioning nomad life style including tele-work. (Sorry, English page is in preparation)Common Note
