Abstract: PROBLEM TO BE SOLVED: To easily make the fermentation state of organic waste uniform by providing the apparatus with a moisture regulation mode to execute agitation by moving an agitating means and a fermentation mode and having the moisture regulation mode selected when feeding the fresh organic waste. SOLUTION: Moisture contents in the organic waste 2 stored in a treating vessel 5 are detected by respective moisture meters 41 and 42. Respective blowers 24, 28, 34, etc., are operated with a small air quantity in the fermentation mode by a controller 11 and respective heaters 25, 31 and 35 are operated at low temperature. When the fresh organic waste 2 is fed from a feeding port 6 into the treating vessel 5 in this state and the moisture content detected by the moisture meter 41 attains >=70%, the fermentation mode is changed over to the moisture regulation mode by the controller 11 and the agitating means 14, etc., are actuated by the moisture regulation mode. The blower 24 is operated with the large air quantity and the heater 25 is operated at high temperature in the moisture regulation mode.

Title: Damage evaluating device for structure member
Inventor: KABETANI ZENZABURO
IPC: B32B7/02
Filed: 1987-02-25
Abstract: PURPOSE:To confirm a damage position in two dimensions and to reduce the fatigue at the time of inspection by weaving optical fibers into meshes before lamination caking when a structure member is made of a composite member and coupling both ends of the optical fibers to a light source and a photodetector. CONSTITUTION:The optical fibers 1 before the lamination caking are woven into meshes in the thickness direction. One-terminal sides of the optical fibers 1 are bundled and coupled with a LED 2 and the other-terminal sides are coupled, one by one, with a photodetector array 3. Light emitted by the LED 2 passes through the fibers 1 and is detected by the array 5, but if the composite member is damaged to enter an interlayer peeling state of interlayer shearing state, the array 3 does not detect the light signal because of the breaking of a fiber 1. The light signal is converted by the array 3 into an electric signal to display a fault position and a date on a display device 5 through a controller 4. The damage position of the composite member is therefore detected instantaneously in two dimensions. Consequently, the fatigue at the time of the inspection is reduced.
