Abstract: PROBLEM TO BE SOLVED: To prevent a stirring means from rotating idly and thereby, ensure the continuation of a stable stirring operation so that garbage can be positively decomposed in a short time by providing a scraping device so that an object to be decomposed such as garbage is guided into the operating range of the stirring means. SOLUTION: A lid with an exhaust aperture 11 is provided on the top part of a decomposition tank 1, then an object to be decomposed A such as garbage is dumped into the tank 1 from a garbage loading aperture 7, and the lid is closed. Further, a rotary shaft 3 begins to rotate by activating a timer switch 10 arranged on the upper face of the decomposition tank 1. Consequently, the object to be decomposed A staying within the rotating area of a helical blade 2 ascends as shown by an arrow, then spreads beyond the rotating area in the uppermost layer of the decomposition tank 1, and begins to descends. Next, the object A is scraped into the rotating area of the helical blade 2 with the help of an auxiliary blade 4 and a rising piece 4a at the lowermost layer of the decomposition tank 1 and again ascends.  Thus it is possible to promote the fermentation and decomposition action by microbes due to the stirring of the object A circulating in the tank 1 and thereby accelerate the decomposition of the object A such as garbage.

Title: Illumination device and display device using the same
Inventor: YUASA KOYO
IPC: F21V8/00
Filed: 1994-06-06
Abstract: PURPOSE:To make it possible to realize a reduction in thickness and excellent illumination efficiency by irradiating the observation surface of an object to be illuminated with the light scattered by light scattering parts from the rear surface of a light transmission plate. CONSTITUTION:The incident light on the light transmission plate 3 from a light source 1 progresses while repeating reflection in the light transmission plate 3. This light is partly scattered by the scattering parts 4 formed on the front surface side of the light transmission plate 3. Of the light further scattered downward, the light having a steep angle with the rear surface of the light transmission plate 3 deviates from a total reflection condition and is emitted from the rear surface of the light transmission plate 3. The object 6 to be illuminated arranged below an illumination device is efficiently illuminated. On the other hand, the light is usually scattered to the front surface side of the light transmission plate 3 as well from the scattering parts 4 and, therefore, light shielding parts 5 are arranged on the front surfaces (observation surfaces) of the scattering parts to provide a structure to prohibit direct viewing of the scattered light. Then, an observer eventually sees only the light reflected by the object 6 to be illuminated among the scattered light rays as the observation light from the spacings between the scattering parts 4. The improvement in the illumination efficiency and the uniformity of display are thus assured.
