摘要:
Present invention is disclosed by a slow closure system developed for toilet covers and operation method of said system. Said system comprises at least one main shell (A) comprising at least two projections (14) extending from inner surface (A') towards inside of it; at least one shaft (B) placed into said shell (A) and having at least one channel (8) on it; at least one plate part (2) which can move by settling in said channel (8); fluid having a certain viscosity and added into the shell (A) before the shaft (B) is placed into the shell (A); sealing elements preventing the shaft from being displaced from the shell (A) when the shaft (B) is placed into the shell (A).
摘要:
The method of the present invention is the method for metal-based coating of the vitrified ceramic articles by means of physical vapor deposition (PVD) technique. After the ceramic articles to be coated are placed on the anode while metal based material are placed on the cathode in the vacuum chamber, the air in the vacuum chamber is evacuated at first and second stages; the cathode surface is cleaned with the plasma at the third stage; the ceramic surface is subjected to ion etching at fourth and fifth stages; non-reactive coating of the ceramic surface by means of the plasma is performed at the sixth stage; reactive coating of the ceramic surface by means of the plasma is performed at the seventh stage in this method.
