Title: Semiconductor device and manufacture thereof
Inventor: KADOTA KENICHI
IPC: H01L21/768
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor device in which the flexibility of selection in a mask material is increased irrespective of the electric characteristic of the mask material itself, and in which an interlayer capacitance capable of preventing the short circuit of an interconnection with a contact due to the damage of a sidewall protective film can be reduced. SOLUTION: When a self-aligned contact part 19 in a buried interconnection is formed on a semiconductor substrate 10, a mask material 16 such as an amorphous Si mask material is used as a mask material used as a stopper film. Then, after the contact part is formed, the mask material is replaced with a silicon oxide film. The stopper film which is used as the mask material is formed at a low temperature of 550 deg.C or lower by a low-pressure chemical vapor deposition(LPCVD) operation. The mask material arranged on the buried interconnection is replaced with another material after a connecting interconnection is formed. Consequently, the electric characteristic of the mask material is not disregarded, and the degree of freedom of the selection of the material is increased. Consequently, a good embeddability is displayed even at a low temperature.

Title: Contamination-proof treatment for outer plate part of ship
Inventor: DOI HIROSHI
IPC: B05D5/00
Filed: 1984-03-22
Abstract: PURPOSE:To economize contamination-proof paint without reducing the contamination-proof effect by setting the thickness of the dry coated film of self polishing type contamination-proof paint applied onto the ship bottom flat part of a swollen ship within a range of 10-85% of that of the dry coated film on the side part of the hull. CONSTITUTION:As for a swollen ship having a square factor of 0.7 or more, the local frictional resistance value calculated along the set stream line on the diagram does not necessarily relate with the consumption amount of the coated film of self polishing type contamination-proof paint, and it is made clear that on the ship bottom flat part and the side part of the hull where the local frictional resistance value is nearly equal, the consumption amount of the painted film on the ship bottom flat part is markedly smaller than that on the side part of the hull. Therefore, the thickness of the dry coated film of the self polishing type contamination-proof paint applied onto the ship bottom flat part is set within a range of 10-85% of that on the side part of the hull, and thus expensive contamination-proof paint can be economized without reducing the contamination-proof effect.

Title: Compression-vacuum device of rotary pump by using ring
Inventor: TAKEUCHI KINICHI
IPC: F04C18/32
Filed: 1979-05-04
Abstract: PURPOSE: To raise the durability, the generated pressure and the output by forming a device so that a ring fitted to an eccentric rotor is connected with a blade and thereby reducing the velocity of the friction between the outer periphery of the ring and the inner periphery of a casing.  
     CONSTITUTION: An eccentric rotor 3 is fitted with a ring 4 connected with a blade 5, while the outer periphery of the ring 4 performs friction and rolling movements along the inner periphery of a casing 1 in proportion to the rotation of the rotor 3. The friction velocity is the product obtained by multiplying the difference between the inner periphery of the casing 1 and the outer periphery of the ring 4 by the number of rotation of the rotor 3. This is about 1/8 of the existing method and, since the contacting and rolling movement is conducted at the fixed positions on almost all over the outer periphery of the ring 4, it has a merit for maintaining airtightness and also has raised durability. Thus, this method does not require employment of a large quantity of oil for the purpose of maintaining airtightness and high processing precision, while enabling the manufacture of a device of large size and with large output.
