Carpenter designs each house and woodworking timber on the construction site. , manufacturer of timber processing machine, planned to improve with developed machine by pre-cut or previously cut to column and beam from timber at factory, instead of process timber on site, however, carpenter have not accepted improved system until trend changed housing market and labor shortage in 1978. Computer-aided design, CAD and Computer-aided manufacturing, CAM is further added to total system in 1985, then this ''Timber pre-cut system MPS-1'' had changed construction with pre-cut method expanded to 93 percent today. – Aichi Prefecture *No. 116: Hand-cranked Garabo Spinning Machine. Meiji (era), Meiji government aimed to more productivity of cotton yarn production with imported cotton-spinning machinery, but machines were so expensive. invented simple hand rotating low cost ''Gaun-method cotton-spinning machine'' () or Gara bo, then exhibit next year at first National Industrial Exhibition in 1877.Machine nicknamed Gara bo, short form of, due to operating sounds ''gara gara'' as onomatopoeia The machine was well evaluated at exhibition, and applied for larger diameter or thicker cotton thread producing, actually machine drive by

, in Mikawa Province where such industry had been leading and became top level of producing area, then machine deployed widely in country. After

, lifestyle changed and Western machines again used, because of Gara bo specialized for larger diameter or thicker thread, not for small diameter or thin thread, so that the peak number of machine working was in 1960, several number of machine still working today. Certified machine is made in 1880s, displayed at in Osaka. Gara bo machine contributed thread spinning industry, yarn export from Japan, and acquisition of foreign currency to Japan. Precise replica is demonstrating at Toyota Commemorative Museum of Industry and Technology in Nagoya. -
