IPC: C02F3/28
Filed: 1980-06-06
Abstract: PURPOSE: To provide an apparatus having a mobility, a relatively simplified installation and a big gas generation ratio, by forming a prefermenting zone and a main fermenting zone in a horizontally long cylindrical vessel,  maintaining the latter zone at a proper temperature, and breaking the uppermost scum layer in the latter zone at a proper time.  
     CONSTITUTION: A horizontally long cylindrical vessel 4 comprises a heat insulative body 1 and end plates 2, 3.  The vessel 4 is pivoted by base stands 5, 6 at an inclined angle, and provided with a functional shaft 16 rotatably supported at the central parts of the plates 2, 3. An air-extracting pipe 23 is opened, and material such as  excretions, urines or the like is charged through a charge opening 7 at the upper part of the plate 2, while  methane bacteria are mixed with the material. The charged material moves from a prefermenting zone 17 along  the inner bottom of the vessel 4 through an opening 19 at the lower part of an under-notched round partition plate 15 into a main fermenting zone 18. The volume of the material gradually increases and reaches a  predetermined upper level (a). A heater of an electric heating device 24 is then actuate by a thermosensor 28  and a temperature control box 30, to keep the material in the zone 18 at a proper temperature. When the  methane fermentation advances to a predetermined pH level, the pipe 23 is closed, and the methane gas consequently flows smoothly to an extracting opening 20. The upper-most scum layer formed in the zone 18 is broken by swinging blades 28 on the shaft 16 with a handle 27. Excess sludge water is discharged through an  outlet 10.

Abstract: PURPOSE:To make it easy to control the position and the width of an active layer at the time of mesa-etching, by providing one or more P-N junction on both sides of the stripe of the inverse mesa type, and installing the boundary surface of the P-N junction between the narrowest part and the upper end of the stripe of the inverse mesa type. CONSTITUTION:The active layer 2, the P-type buffer layer 8, and the P-type clad layer 3 are grown in order on the N-type substrate 1. After the stripe mask is formed and only the clad layer 3 on the buffer layer 8 is subjected to the selective etching to form the mesa, the active layer 2 and the buffer layer 8 are subjected to etching and the inverse mesa is formed. The mask is eliminated, and the P-type current blocking layer 4, the N-type current blocking layer 5, the P-type layer 6, and the P-type cap layer 7 are grown. In this process, the thickness of the P-type current blocking layer 4 is made smaller than that of the P-type clad layer 3, and creeping of the layer 4 is restrained by virtue of the inverse mesa. The current blocking layer of the P-N junction is formed in the middle part of the inverse mesa. Thus, the control of the position and the width of the active layer at the time of mesa etching is made easy, and the current blocking layer can be made uniform.
