Title: Method of isolating transistor
Inventor: HAWAADO ERU TEIGERAA
IPC: H01L21/762
Filed: 1995-04-20
Abstract: PURPOSE: To minimize the dimensions of a trench used for isolating a transistor, by utilizing a material with a small permittivity for burying the trench. CONSTITUTION: A mask layer 52 is deposited on a semiconductor substrate 50, and the mask layer 52 is patterned in a trench shape. Then, a trench 54 is etched into the semiconductor substrate 50, and the mask layer 52 is removed. The semiconductor substrate 50 is oxidized and an oxide layer 56 is formed. Then, a layer 58 made of a material with a low permittivity whose value is less than 3.3 is deposited on the semiconductor substrate 50, and a part of the layer 58 that is not within the trench 54 is eliminated. Therefore, since a dielectric material with a small dielectric constant buried into the trench 54 decreases the coupling of capacitance between devices, the depth and width of the trench can be reduced.

Title: Air closing preventive device for membrane filtration for waterworks
Inventor: JINBO KICHIJI
IPC: C02F1/44
Filed: 1993-04-01
Abstract: PURPOSE:To prevent the decrease in an effective filtration area by generation of an air pool on a rear stage filter membrane primary side and to prevent the air closing of the pipeline of washing pipings at the time of back flow washing by automatically discharging the air bubbles generated from the water permeated through a front stage filter membrane to the outside of the system between the front stage filter membrane and the rear stage filter membrane. CONSTITUTION:The air bubbles are liable to be generated in the treated water of the front stage membrane as there is a rise of water temp. and a pressure difference arises at the time of passage through the membrane, because energy of cross flow is applied to raw water. The generated air bubbles are accumulated in the water flow route, and further, kept accumulation by flowing to the primary side in a rear stage membrane module 13. This air is, thereupon, expelled by an air vent valve 14 to prevent the decrease in the area of the rear stage membrane. The washing water is passed through a piping 17 from a washing water tank 19 and is pressurized by a washing pump 18 at the time of a back washing stage. A valve 11 is closed and a valve 12 held open and the air remaining on the secondary side of the front stage membrane module 6 is discharged from an air vent valve 9. The waste water of washing on the primary side of the front stage membrane module 6 is discharged from a drain pipe 5.

Title: Exhaust device of multicylinder engine with supercharger
Inventor: OKIMOTO HARUO
IPC: F02B37/18
Filed: 1980-07-14
Abstract: PURPOSE: To enhance the turbin efficiency by making dynamic pressure supercharge in the full operating range regardless of the performance of a waste gate by such an arragement that one group of exhaust passages are set longer than the other group and that a by-pass passage is opened in the exhaust passage of the other  group.  
     CONSTITUTION: The exhaust passage 3a of the cylinder 1a in Group 1 is set longer than the exhaust passage 3b of the cylinder 1b in Group 2, and the upper flow open end 5a of the by-pass passage 5 is opend at this exhaust passage 3b. At the low revolving time of engine 1, nonacutation of a diaphragm 8 will choke the by-pass passage 5 to allow the exhaust gas in the exhaust passages 3a, 3b to flow into a turbine 2a, so that the exhaust pulsations of the cylinders 1a, 1b are multiplied and dynamic pressure supercharge is thus performed. At the high revolving time of engine 1, on the other hand, actuation of a waste gate will open the by-pass passage 5, so that the flow of exhaust gas to the turbine 2a will decrease and the amount of supercharge is controlled properly.
