To solve the problem of labor shortage due to the decreasing production-age population in Japan, productivity improvement using robot technology and the Internet of Things has been gaining great demand in various fields. Accordingly, the Ministry of Agriculture, Forestry and Fisheries of Japan has proposed development of smart agriculture, and agricultural machinery manufacturers have been developing robot technology for agricultural machinery. Furthermore, in Iwate Prefecture, as part of the agriculture promotion plan, the scale and profit of onion cultivation are being increased by developing the seedling raising technology. In this study, the authors focus on the seedling raising process adopted in house and further develop a robot-technology-based device that can increase the scale of onion production.

using Sinker Electric-discharge Machining
TAKESHI Wago and SEIKI Chida
To investigate the applicability of sinker electric-discharge machining to digital shibo machining (i.e., digital surface texturing), shibo (i.e., texture) patterns are classified by the size of the shibo bit (i.e., texture element). In particular, the effect of pear skin (satin-like surface) of steel is examined for an extremely small shibo bit. In order for the shibo bit to not sink into the pear skin surface, a certain height of the shibo bit (PV value) must be maintained on the electrode of the sinker electric-discharge machine. Finally, the threshold size of the shibo bit is found to be at least 54.5 ȝm.

resin 3D printer
TAKESHI Wago, HIROYUKI Nagashima, TAKASHI Kikuchi
and SHINGO Kurosu
The coordinates of hole-plates prepared with a resin 3D printer are measured by a coordinate measuring machine using image processing. Two-dimensional correction of the measured coordinates of the hole plates performed on the X-Y plane of the hole plate. For this purpose, the correction amount is back-calculated from the deformation ratios of the measured coordinates after the first printing of the hole plate by using the design value of the resin 3D printer. The average deformation ratio is 99.84% in fused deposition modeling (FDM) and 99.60% in laser beam lithography (LBL). Next, after the second printing of the hole plate by using the deformation ratios, the average position error becomes 8.52 ȝm in FDM and 27.89 ȝm in LBL. The position errors are thus reduced to one-fifth of those in the first printing and the effect of dimension correction method is confirmed.

Application of bending wood compressed by Compwood system
to home products
YASUHIRO Aruga and YASUJI Naitou
We have already found that compared with unprocessed wood, woods that is compressed by the Compwood system has a low elastic modulus and the compression-holding time is made longer, the bendable radius becomes smaller. On the basis of these findings, several wooden products such as furnitures have been proposed and made as a trial to reduce the constraints in designing of bent-wood products. Furthermore, these products have been evaluated by visitors at trade -exhibitions.
key words : Compwood-system, Bent wood, Wood processing

Suitability of lactic acid bacteria isolated from koji (rice malt)
for producing sake starter
NARUHIDE Sato and YUICHI Yonekura
In Sokujo brewing of sake, commercial lactic acid is added to the starter (shubo). In this study, we show that lactic acid bacteria screened from factory-derived malted rice (kome-koji) can be added to the starter of Sanki-amazake sake brewing. We perform a pilot-scale brewing using this method. Furthermore, it is confirmed that the number of production days for brewing the starter is the same as that by using the Sokujo method.
