Title: Acoustical material
Inventor: OKUDAIRA YUZO
IPC: G10K11/16
Filed: 1989-01-13
Abstract: PURPOSE:To improve the acoustical absorptivity in a low frequency region without increasing the thickness of the material by incorporating flakes at a specified weight ratio into the foamed body of a high-polymer material. CONSTITUTION:The acoustic material is formed by incorporating and dispersing 50 to 300pts.wt. flakes of mica or the like into 100pts.wt. high-polymer material in the production process of the foamed body of the high-polymer material, such as urethane. The flakes 3 having about the same grain sizes as the grain sizes of holes 4 are selected. The flakes 3 project into the holes 4 and constitute the intricately nested shapes when the foamed body 2 is formed and, therefore, the energy of propagating sound waves is easily absorbed and since the flakes are oscillated by the sound waves, the sound waves are converted to mechanical energy. The acoustical absorbing effect is eventually enhanced. The acoustical material having the sufficient acoustical absorptivity in the low-frequency region is obtd. in this way without increasing the thickness of the material.

Abstract: PURPOSE:To enhance workability for the mounting and detachment of a sorting net body by providing a grain guide cylinder having a guide blade provided thereto in a wound state and a grain receiving cylinder to the lower part of a shell body. CONSTITUTION:Unsorted grains are sent into a grain receiving cylinder 60 from a supply hopper 14 and pushed down by the guide blade 55 of a grain guide cylinder 50 to be introduced into the cylinder 50 by a grain guide port 54. The grains are scraped up by the spiral blade 32 of a grain lift spiral body 30 to be scattered to the inner surface of a sorting net body 40 and small grains pass through the small holes 41 of the sorting net body 40 to be sorted. Good grains are sent upwardly to fall in a good grain guide trough 24b and scraped out by a scraping-out blade 45 to be sent to a storage tank 13. The small grains fall downwardly in the outside of the sorting net body 40 to fall on the partition disc 52 of the grain guide cylinder 50 and sent to the rear opening of a small grain discharge pipe 15 to be discharged to the outside. By this method, the replacing work of the sorting net body can be made easy.

Abstract: PROBLEM TO BE SOLVED: To provide a work vehicle, such as a combine harvester, not causing the longitudinal inclination of the vehicle body on its backward travel. SOLUTION: This work vehicle is provided with a travel device 3 having crawlers 14, a vehicle body inclination-detecting means 5 for detecting the longitudinal inclination state of the vehicle 2, a vehicle body-lifting means 4 for lifting the vehicle body 2 on the basis of the travel device 3, and a horizontally work vehicle body-controlling means for inputting the inclination detection signal of the vehicle body inclination detection means 5 and driving the vehicle body-lifting means 4 and a longitudinally vehicle body-inclining means to automatically horizontally control the vehicle body. When the work vehicle is backward moved in a constant distance such as a meter, the horizontally vehicle body-controlling means is stopped.  After the backward travel of the work vehicle only in the constant distance in the state free from the horizontal control, the horizontal control of the vehicle body is restarted. Thus, while the work vehicle is backward moved in an inclined state in the constant distance without causing such an action that grain straws are pulled out with a reaping device of the work vehicle or such an action that grains in the upper ear portions of grain straws are squeezed and threshed, the trouble is eliminated, and the horizontal vehicle control is subsequently returned to the automatic control. Thereby, the subsequent operation of the work vehicle is smooth.
