<p>In recent years, the Japanese government has encouraged soybean planting. However, the suitable seeding period is only for 2 weeks, and more than 80 % of soybean fields are converted from rice paddy. The purpose of this study was to improve existing seeding techniques for rapid and stable seeding of soybean in moist soil conditions. A machine that combines rotary cultivation, ridging, and seeding has previously been developed. However, operation speeds were as slow as 0.3-0.6 m/s, and seeding was not effective in the moist soil conditions. In this study, we tested an experimental machine with disk cultivation that achieved a maximum ridging speed of 2 m/s and a new, high seeding speed of 1.5 m/s, which ensured stable seeding.</p>

Development of Energy-saving Ventilation System Considering Inside and Outside Temperatures of a Sawdust-based Shiitake Cultivation Facility Reviewed

The objective of this study was to develop an energy-saving ventilation system for a Shiitake cultivation facility. While in the cultivation stage, the spawns generate heat and CO₂ during their growth. To maintain an optimal growth temperature and labor-safe CO₂ concentration, an air conditioner and ventilation must employed. For energy saving, a heat exchange ventilator is widely used. For a more efficient utilization of this ventilator, we focused on two modes: heat exchange and normal ventilation. When the room temperature is higher than the outside temperature, using cool air with normal ventilation benefits the air conditioner. Moreover, we propose that spawn heat may be used as a heat source with heat exchange ventilation, when the room temperature is low. To determine the ventilation mode, we designed a control unit considering the inside and outside temperatures of a cultivation facility. After operating this system for one year, the highest efficiency was observed at an outside average temperature of 10 to 15℃. Therefore, a 25 % energy saving was achieved in this cultivation facility in Tamano city, Okayama.

画像を用いたパン生地膨張過程の計測 Reviewed

Language：Japanese Publishing type：Research paper (scientific journal) Publisher：美味技術学会

製パンにおいては，生地の材料や調製条件がその品質に大きく関わっており，発酵時に高い膨張を示す生地ほどパンの評価が高いとされている。しかし，これまでのパン生地膨張の計測は接触式の方法であり，本来の生地の挙動を正しく観察することは困難である。また，数値の読み取りにも誤差が生じる場合が多い。そこで本研究では，画像を用いて非接触かつ定量的にパン生地の膨張過程を3次元的に計測する手法を検討した。

Acta Horticulturae 824 237 - 244 2009

Language：English Publishing type：Research paper (international conference proceedings) Publisher：International Society for Horticultural Science

Since citrus is often grown on terraced orchards in west Japan, their qualities and yields are various, because of different environments such as temperature, humidity, solar radiation, precipitation, soil condition, tree age, and other conditions on different elevation fields. In this study, the concept of a mobile fruit grading robot and measurements from the robot are described. This robot consists mainly of a roller pin conveyor, two machine vision systems, an NIR inspection system, a GPS, and a travelling device. One or two operators can operate this robot for harvesting, because the robot keeps a constant distance between operators and the robot by laser sensors as it travels. Harvested fruit are put into the roller pin conveyor through two gates, as information of growth in northern or southern canopy is added for the fruit canopy location. One vision machine inspects harvested fruit, while the other monitors tree leaf color and canopy size. An NIR inspection system measures internal sugar content and a GPS records robot location. It is possible to accumulate fruit color, size, shape, defect, sugar content, tree leaf color, and canopy size into a database corresponding to tree location. Adding to this robot's information, analysis of satellite images is conducted and field-server information is collected. The producers' operation records can be input to the database with the satellite and field-server information. This database is used both for farming guidance to conduct tree management and for food traceability in relationship to safety and security in food distribution.

SURFACE GLOSS MEASUREMENT ON EGGPLANT FRUIT Reviewed

V. K. Chong, T. Nishi, N. Kondo, K. Ninomiya, M. Monta, K. Namba, Q. Zhang, H. Shimizu

APPLIED ENGINEERING IN AGRICULTURE 24 ( 6 ) 877 - 883 2008.11

Language：English Publishing type：Research paper (scientific journal) Publisher：AMER SOC AGRICULTURAL & BIOLOGICAL ENGINEERS

Surface gloss is one of the important quality factors affecting consumer opinion on purchasing eggplant fruits. The current manual gloss grading method is subject to human bias and the outcome is often very ambiguous. This study developed a sensing device consisting of two CCD monochrome cameras and three long tungsten lights and an associated quantitative method of measuring surface gloss of eggplant fruit using the device. Distinguishing various glossiness states of the fruit were made possible by analyzing the specular reflectance of the fruit surface. Specular reflection of the light on fruit surface was measured by digital image analysis method. Gradient filter was applied on the gray-level image for measuring magnitude of intensity changes. The algorithm consistency and validation test on the samples showed the algorithm was feasible of quantitatively, assessing eggplant fruit surface gloss with an accuracy rate of 0.806. Details of the sensing devices, outline of the algorithm and preliminary, results are presented in this article.
