Title: Flocculation reaction device
Inventor: YASUDA TSUTOMU
IPC: B01D21/01
Filed: 1992-01-17
Abstract: PURPOSE:To enable the formation of pellets having larger grain sizes and higher strength than in the case of absence of a pelletizing plate by radially fixing the pelletizing plate inclined in the swiveling direction of stirring vanes to a treating chamber and plunging the pelletizing plate down into the liquid from the liquid surface in the chamber. CONSTITUTION:The pelletizing plate 16 inclined in the swiveling direction of the stirring vanes 12 is radially provided in the treating chamber 1. Sludge tending to form scum by floating on the liquid surface collides against the pelletizing plate 16 at the time of swirling on the liquid surface when the pelletizing plate 16 is plunged downward and shallow into the liquid from the liquid surface. The sludge is crushed at the time of passing under the pelletizing plate and simultaneously the sludge tending to pass under the plate comes into contact with the slope of the pelletizing plate 16 and rolls on the slope. The sludge is thereby pelletized. Then, the sludge having the high tendency to float on the liquid surface is pelletized without forming the scum even if such sludge is supplied. In the case of the sludge having the lower tendency to float on the liquid surface, such sludge rolls on the plate by coming into contact with the plate at the time of passing under the pelletizing plate 16 in addition to the rolling by coming into contact with the inside periphery of the treating chamber 1 and, therefore, there are more chances for the pelletization.

Abstract: PURPOSE:To improve yield by eliminating one part or all of an active layer and a clad layer which do not contribute to oscillation and by making electrical conductive type near the exposed at this surface at this time to that of substrate or by mutually diffusing the component elements of the active layer and the clad layer to form an active area. CONSTITUTION:After forming a clad layer 2, an active layer 3, a clad layer 4, and a contact layer 6 on a substrate 1, the clad layer 2, the active layer 3, the clad layer 4, and the contact layer 6 other than active region are removed. After forming an active region 8, p-type impurities are diffused from the exposure surface and the area closer to the exposure surface of the substrate 1, the clad layer 2, and the active layer 3 is inverted from n-type to p-type. At this time, mutual diffusion occurs between the clad layer 4 and the active layer 3 simultaneously and A1 enters the active layer 3. Then, by allowing a crystal to grow while stripe-like masks such as SiNx and SiO2 are being adhered, a current block layer 5 is formed selectively at a part other than the stripe 8 for feeding current. Then, a stripe-like mask 11 is removed and a contact layer 6 is formed. It enlarges the band gap and reduces reactive current to achieve a low threshold value.
