Title: Cleaning method of water treating device
Inventor: KUROBE HIROSHI
IPC: C02F1/70
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To prevent formation of block aggregates of iron metal particles in a packed layer by aerating the packed layer to loosen the packed layer of iron metal particles, supplying a mixture flow of cleaning water and air as an upward flow. and cleaning to remove contaminants in the packed layer of iron metal particles for specified times. SOLUTION: In the reducing treatment of waste water, the waste water controlled to have <=5 pH is supplied through a water inlet 2 and treated in a packed layer 7 of iron metal particles to reduce impurities such as peroxosulfuric acid in the waste water. When the water treating device is to be cleaned, the waste water is stopped and air is introduced through an air inlet 3 to loosen the packed layer 7. Then a mixture flow of cleaning water and air is supplied as an upward flow through the packed layer 7 to expand and fluidize the packed layer 7. By expanding and fluidizing the packed layer 7, contaminants depositing on the iron metal particles are removed and discharged together with contaminants causing clogging through the discharge port 4. This cleaning process is carried out twice or more times a day.

Title: Manufacture of semiconductor element
Inventor: HASHIMOTO TAKESHI
IPC: H01L27/04
Filed: 1986-06-09
Abstract: PURPOSE:To decrease the concentration of impurities in a second polysilicon layer and to stabilize a high resistance value, by providing a high-melting metal at contacts between first and second polysilicon layers and polyciding the high- melting metal. CONSTITUTION:Contact holes 16 are formed in an insulation film 14 for connecting a first polysilicon layer 13 to a second polysilicon layer 15. After a high-melting metal 17 is deposited on the first polysilicon layer 13 within these contact holes 16, the second polysilicon layer 15 is formed. Thereby, the high-melting metal 17 on the first polysilicon layer 13 is converted into polysilicide so that the first and second polysilicon layers can be ohmically contacted with each other. Further, since the high-melting metal 17 serves as a buffer, phosphorus in the first polysilicon layers can be prevented from being diffused in the second polysilicon layer 15.
