Title: Method of treating liquid containing discharges from living fish and shells
Inventor: NOMURA JIYUNJI
IPC: C02F1/28
Filed: 1977-12-03
Abstract: PURPOSE: To improve the holding density of living fishes and shells in a tank through en efficient oxidation and decomposition treatment of fish discharge-contained water in a small apparatus with a less water ratio by passing thereof through an activated charcoal-packed layer into which a halogen oxidizing agent is continuously fed.  
     CONSTITUTION: Water in a tank which keeps sea fishes such as sea bream, living water fishes such as sweet fish, crustacean such as lobster and crab and shellfish is sent to a layer 2 packed with activated charcoal with thw actuation of a circulating pump 1. Herein, the activated charcoal can employes plant such as wood or palm tree, mineral such as peat or pitch or high molecular compound. A constant amount of a halogen oxidizing agent such as chlorine or hypochlorous acid is continuously fed into the layer 2 fron a storage tank 3 with the actuation of a pump 4. In the layer 2, oxidation and decomposition of discharges from the fishes with the oxidizing agent is performed with an activated charcoal as catalyst. The water thus purified is recycled to the fish tank.

Title: Semiconductor device and its manufacture
Inventor: KONDOU TAKEO
IPC: H01L21/8238
Filed: 1979-11-10
Abstract: PURPOSE:To prevent punching-through and integrate a semiconductor device to a high degree by a method wherrin a corner of a mask for forming a P well of an N type substrate is projected to the inside of a P well region. CONSTITUTION:A corner section of a mask 5 for forming a P well is projected to the inside of a P well region 2. When using the mask, to the corner section thereof a convex section 11 is made up, in this manner, the P well region 2 is sufficiently indented at the corner section. Thus, even when a void L2 between a mask 4 for a P<+> layer 3 and the P well region 2 is reduced, an enough distance can be ensured at the corner section. When a P diffusion layer is built up to an N type substrate, the extension of the diffusion of the corner section depends upon the ratio of the concentration of the surface of the diffusion layer to the cooncentration of the substrate. According to this constitution, however, punching-through is prevented without reducing the ratio, and a degree of integration can be improved.

Title: Gold alloy filler metal for brazing
Inventor: KASHIWAGI KOZO
IPC: C22C5/02
Filed: 1987-06-12
Abstract: PURPOSE:To reduce roughness and ruggedness after brazing and to inhibit tarnish and corrosion by a residual cleaning soln., by specifying the compsn. of an Au alloy filler metal for brazing. CONSTITUTION:This Au alloy filler metal for brazing has a compsn. consisting of, by weight, 10-80% Cu, 0.001-1.5% P, 0.001-1.0% Si and the balance Au. The reason that P and Si are contained in the Au alloy filler metal is that P and Si reduce the surface tension of the filler metal during brazing, suppress the surface roughening of the filler metal and inhibit the occurrence of ruggedness. The P and Si contents are limited because <0.001% P or Si can not inhibit the surface roughening of the filler metal and the occurrence of ruggedness and >1.5% P or >1.0% Si causes the flow of the filler metal to stain the base metal and imparts unfavorable influence on brazing strength.
