    • PURPOSE:To optionally adjust the blow-off direction and the scattering width so that scattering can be performed uniformly, by discharging particles of fertilizer, agricultural chemicals, etc. from a slender discharge port of the bottom part of a hopper, giving a blow by a moving blade which is capable of adjusting its mounting angle and moving up and down, and radiating them. CONSTITUTION:From an input shaft 13 and a speed change gear 12, which have been connected to a PTO shaft of a tractor, a feed roll 8 and a moving blade 10 are rotated in each prescribed direction through an output shaft 14 and a belt transmission system 15, and a rotary shaft, respectively, particles are dropped from a discharge port 6 so as to form a thin layer, and are scattered to both sides of the running direction by giving a blow by use of the moving blade 10. In this case, as for the particles in a hopper 5, its flow rate is adjusted by changing the rotational frequency of the feed roll 8, and also as for the particles hit by the moving blade 10, a scattered distance is small in the part being near the center of rotation, having a small radius of gyration, on the contrary the scattered distance is large in the part being far from the center of rotation, and they are scattered uniformly. Also, desired scattering width and distribution state are obtained by adjusting a speed of rotation of the moving blade and a mounting angle of the blade.

    • METHOD FOR MEASUREMENT OF HEAT CONDUCTIVITY AND HEAT CAPACITY

    • PURPOSE:To make the simultaneous and accurate measurement of heat conductivity and heat capacity possible through measurement for some ten seconds by sandwiching a material to be measured beteen two pieces of standard materials of known heat conductivity and heat capacity and mutually different temps., and measuring the change in the temp. on the contact surfaces of the respective materials. CONSTITUTION:As a standard material on a heat accepting side, a thick acrylic plate 2a is used, and a thermocouple 4 for temp. measurement is beforehand affixed in the central part on the top surface thereof. On the other hand, as a standard material on a heat supplying side, a thick copper plate 3a is used, and a thermocouple 5 for temp. measurement is beforehand affixed on the surface to be brought into contact with an object to be measured (for example, a living leaf of pasture, etc.) 1a. The surfaces other than these surfaces are kept covered with heat insulating materials 6. Prior to measurement, the thickness of the sample is measured, after which it is brought in tight contact with the central part on the top surface of the plate 2a, and these are left standing at room temp. until the plate 2a and the sample 1a attain an equal temp. Thereafter, the copper plate 3a is maintained at temp. higher by a few degrees than room temp. in a thermostat and is removed from the chamber and is brought quickly into tight contact with the sample 1a. In about 30 seconds right after the tight contact, the temps. of both contact surfaces are measured with the thermocouple 45 and the heat conductivity and heat capacity are known by using a graph obtained beforehand from the relations.
