Filed: 1992-02-26
Abstract: PURPOSE:To simply classify the strength and static Young's modulus of sawn wood by using a natural oscillation frequency of a third order or higher even under a condition that the oscillation of a log is restricted. CONSTITUTION:In a state that cut down logs 1 are left on the ground or that their oscillation is restricted such as in a state that they are heaped up as shown is the figure in a raw lumber market, that is to say, under a condition that the position of every node and every antinode of fundamental oscillations of the logs is restricted, longitudinal oscillation sounds generated when one edge of every log 1 is hit by a hammer 2 or the like are caught by a microphone 3 which is placed on the other edge. Then, in a simple classification method, a natural oscillation frequency of a third order or higher out of resonance frequencies obtained by analyzing the frequency by an FET(Fast Fourier Transformation) spectrum analyzer 4 is adopted, and the strength and static Young's modulus of sawn wood are estimated.

Abstract: PURPOSE:To prevent a drug from deteriolating in quality due to moisture content, by feeding a proper quantity of drugs to a feeder for granules and powdery drugs in case of sterilizing waste water or the like while storing the drug without being touched to water, and installing a device keeping the concentration constant. CONSTITUTION:Drugs inside a cylinder 1 enters the inside of a control cylinder 4 and they are drop to the inside of a chute 8 as being controlled by two control plates 5 and 6, from which they drop on circular plates 11 and 12. At this time, partial dugs are stored in a lower end part of the small diametral circular plate 11 in pile, which another part drops on the large diametral circular plate 12 by way of the circular plate 11 or directly from the chute 8. At that time, since these circular plates 11 and 12 are overlapped with each other at some part, these drugs are in no case dropped down. But, when waste water increases in quantity and a float 21 goes up, each of rotary plates 9 and 10 rotates clockwise. With this rotation, the overlapped part also rotates whereby these drugsmounted on the circular plate 12 drop as well. At this time, drugs inside the chute 8 are blocked up by the circular plate 11 so that they are never discharged out but merely a fixed quantity.
