摘要： PURPOSE:To readily and accurately assess the presence/absence, period, and degree of environmental contamination in the atmosphere, soil, etc., and influence of the environmental contamination on the biological system by analyzing leaf parts of trees and plants as analysis samples and assessing the existing states of various kinds of materials in the natural world. CONSTITUTION:The presence/absence of contamination can be confirmed when the leaf part 1 of evergreen trees are selectively analyzed for sulfur S and fluorine F. Since the disorder caused by atmospheric pollution tends to appear as a discolored part at the front end part E11 of a leaf as shown in Fig. (a), one leaf is cut and classified into three parts of the front end part E11, an intermediate part E13, and central part E15. It is desirable to cut the parts E13 and E15 in the same width. Since, the disorder caused by sulfur is apt to appear at the intermediate part E23 as shown in Fig. (b), one leaf is cut and classified into three parts of a front end part E21, intermediate part E23, and central part E25 at the time of assessing soil contamination.

摘要： PURPOSE:To reduce the height of a waveguide by forming a recess receding in the direction opposite the side of the magnetron attachment portion on which the waveguide is to be secured and attaching the antenna of the magnetron to the bottom surface of the recess so that the antenna projects into the waveguide. CONSTITUTION:A magnetron attachment portion is formed so that one end of a ceiling plate 15 of a frame defining a cooking chamber 13 and a mechanism compartment projects into the compartment 14. A recess 19 and a through hole 20 are provided which recess 19 recedes in the direction opposite the side where a waveguide 17 is to be secured. A magnetron is attached to the bottom surface of the recess 19 so that the antenna is projected through the through hole 20 into a tube 17. Therefore, the tip of the antenna is located lower by the depth of the recess 19 formed in the magnetron attachment portion. This permits to lower the height of the tube 17 without being limited by the antenna height, to reduce the external height of the main body and to make the device compact.

摘要： PURPOSE:To efficiently capture and thicken the extremely trace gaseous components in the atm. air by causing the low-temp. chemical adsorption of said components into an inert liquid refrigerant. CONSTITUTION:Head operated valves 4, 9 are opened and a hand operated valve 13 are closed to introduce the liquid refrigerant 26 from a liquid refrigerant introducing pipe 3 into a capturing vessel 2 and the air is blown from an air introducing pipe 28 into the refrigerant 26, by which the contaminants, malodors and smell components contained in the air are captured in the refrigerant 26. After these components are sufficiently captured, the valve 4, 9 are closed and further, a hand operated valve 25 of a thickening vessel 15 is closed and the hand operated valve 13 of a liquid refrigerant transport pipe 12 is opened to transport the refrigerant 26 into the vessel 15 by the internal pressure of the refrigerant evaporated in the vessel 2. Only the refrigerant 26 in the vessel 15 is gradually evaporated to vapor which is discharged from a discharge pipe 18, if the vessel 15 is shut off from the vessel 2 when the refrigerant 26 is filled in the vessel 15. The whole refrigerant 26 in the vessel 2 is evaporated in the vessel 15 by repeating the evaporation of the refrigerant 26 in the vessel 15 and the replenishment of the refrigerant 26 from the vessel 2 to the vessel 15, by which the captured components in the refrigerant 26 are thickened.
