The heat quantity of about 63 per cent of the outside solar radiation becomes the effective heat source for drying the domestic leaf tobacco at a curing house with the trasparent roof and walls.
The whole house receives the heat quantity of the solar radiation as 1.57 times as that of the solar radiation at the horizontal floor area.
Instead of the integrated calculation of the incoming radiation through each walls, the author proposed a simple calculation method of the effective heat quantity for curing by drawing the hourly shade figures of the house and calculating the value; shade area×horizontal solar radiation×effective transmission coefficient.
The value of 0.52-0.63 was obtained as the rate of utilization of the effective heat quantity to cure raw tobacco leaf in the house.
This shows the curng house is effectitve enough as a type of the energy saving facilities.

Paddy drying and storage facilities do not exhibit completely their capacities because of a short term usage and large variances of quantity and moisture content of collected paddy. This paper was aimed, therefore, to relate the data to an optimum design of the facility, clarifying a state of collected paddy; moisture content, quality, collecting period, quantity per day and quantity variation in the term, in relation to weather condition, paddy variety, harvesting method, regional feature, and so on.
Furthermore, a measurement precision of moisture content and influences of hulling recovery rate and rice quality to a marketing rice are investigated in this paper, since the collected paddy by each farmer with different quantity and moisture content is treated in a lump after receiving.
