太陽熱利用による穀物の人工乾燥(II) : ビニールハウス利用乾燥設備の所要規模について

application/pdfAssuming that solar dryer system using the green house as a solar collector is incorporated into the mechanized rice cropping operation system most popular in our country, studies were made to determine the facility scale of dryer system required for performing grain drying smoothly. The salient points obtained are as follows: 1)First, study was made concerning how much holding capacity is required for the grain dryer utilizing solar energy. Formula (2-2) was proposed with which the optimum holding capacity of the dryer can be calculated on the basis of daily harvesting amount of grain by combine. Next, required drying quantity per day was determined from the standpoint of full use of the drying the proper harvesting period. Then formula (2-5) was derived as a calculation formula to obtain that holding capacity of a dryer which is calculated on the basis of above required drying quantity. 2) By picking up factors having effects on the area of a solar collector house, all of those characteristics are made clear. From these date, formula (2-11 & 2-12) were proposed to calculate adequate area of the collector house. House area (㎡)/Grain (100㎏) and Air volume (m³/sec)/House area (㎡), required for calculation of adequate house area, in relation to the collector efficiency of the house, air temperature rise within the house and drying rate, were represented graphically based on the results of experiments conducted up to the present. Numerical values required for calculation of adequate house area can be read there-from.departmental bulletin pape

伝送路の状態を考慮したマルチキャリヤ伝送用回線制御方式

マルチキャリヤ信号のサブキャリヤから伝送路の状態を比較的容易に推定できることに着目し、これを利用して伝送品質を向上させるマルチキャリヤ伝送用の回線制御方式を提案する。提案方式では、受信電力が小さく伝送品質が劣化していると予想されるサブキャリヤにはデータを割り当てずにダミーキャリヤとして送信し、受信電力が大きく伝送品質が良好であると予想されるサブキャリヤのみにデータを割り当てて伝送する。移動通信環境を想定した性能評価の結果、すべてのサブキャリヤにデータを割り当てる通常のマルチキャリヤ伝送方式に比べ、受信レベルの低いサブキャリヤをダミーキャリヤとしてデータを割り当てない提案方式のほうが、伝送効率が向上することを示す。更に提案方式における誤り訂正符号の効果を明らかにする。journal articl
