Title: Electrochemical oxygen generator by solid oxide
Inventor: UIRIAMU FUEDASUKA
IPC: H01M8/24
Filed: 1991-02-02
Abstract: PURPOSE: To produce oxygen having extremely high purity at a low cost from the oxygen in air by connecting plural cells having dense solid oxide electrolytes, porous oxygen electrodes and porous air electrodes in series, thereby constituting an oxygen generator.  
     CONSTITUTION: This oxygen generator 10 comprises plural cells consisting of a first cell 12 and adjacent cells 12'. These cells are electrically connected in series via solid oxide electrolytic zones or segments 14, air electrode zones 16, interconnected segments 18 and oxygen electrode zones 20. When the electrons (e - ) from a DC power source are supplied from a negative terminal 24, a current passes the air electrode 16 of the cell 12' and the O 2  in the air 23 is reduced at the running temp. of the oxygen generator heated by an internal heater to produce O -  ions. The 0-ions passed in the solid oxide electrolyte 14 are recombined by the oxygen electrode 20 and forms the pure gaseous oxygen. This oxygen passes the porous supporting body 22 and is collected as the high-purity gaseous O 2  in a central chamber 25. The electrons (e - ) return from the anode terminal 26 to the power source.

Title: Manufacture of soi-mosfet
Inventor: MUKAI RYOICHI
IPC: H01L21/20
Filed: 1986-02-20
Abstract: PURPOSE:To prevent carriers from scattering, by carrying out doping with an SiO2 film used as a mask for forming source and drain regions, forming a gate electrode having a width smaller than that of a region where no grain boundary exists, and forming LDD sections in self-aligning manner with the gate electrode used as ask. CONSTITUTION:An anti-reflection film 3 having an aperture 31 is carried on a silicon layer 2 formed on an insulator substrate 1. A laser beam is applied thereto from above. Since the silicon layer region 2 absorbs well the laser beam, recrystallization can be realized in a manner that any grain boundary is eliminated from the part 21 of the silicon layer present below the aperture 31. The silicon layer is selectively oxidized by using the anti-reflection film as a mask so that an SiO2 film 32 is formed in the aperture. The anti-reflection film 3 is then peeled off, and doping is performed for forming source and drain regions. After that, the SiO2 film 32 is also peeled off. A gate oxide film 5 is provided while an element is isolated. Finally, a gate electrode 6 having a smaller width than that of the aperture is formed. Using this gate electrode 6 as a mask, doping is performed to form LDD sections 7 and 8. The process as described above can prevent speed-up dispersion of dopants or scattering of carriers.

IPC: F16L21/04
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a hose coupling capable of being rotated according to the counterpart position in the piping construction without deteriorating the appearance. SOLUTION: In a hose coupling 10,. an outer annular groove 20 is formed on the inner peripheral surface on the other end side of an elbow pipe 12. An inner annular groove 32 is formed on the outer peripheral surface of an inner cylindrical part 24 so as to face the outer annular groove 20, and a U-shaped engaging ring 34 is fitted into the inner annular groove 32.

Therefore, a hose 42 can be reasonably connected with it fitted to the piping form without resisting the bending tendency, and the appearance after piping can be secured.

Title: Dewatering work for soft ground
Inventor: HATANO HITOSHI
IPC: E02D3/10
Filed: 1982-03-05
Abstract: PURPOSE:To enhance drainage efficiency of sludgy layer by a method in which a granular dewatering agent layer of a specific composition is formed on the surface layer of the sludgy layer in such a way as to drain the leachate. CONSTITUTION:On the surface layer of a sludgy layer (A), a granular dewatering agent layer (B) composed primarily of inorganic industrial wastes (e.g., one or more of blast furnace slag (water-granulated), laitance of cement, red mud, etc., and humic acid-containing substances such as humid soil, peat, lignite, etc.) is provided. By this, the dewatering agent constituting the layer (B) is swelled with water contained in the sludgy layer (A) and therefore, the moisture of the sludgy layer (A) is absorbed by the layer (B) and discharged to the ground surface with the lapse of time. Then, the dewatering agents come to bury the apertures (voids) among the adjacent dewatering agents to become a better water-permeable layer. Thus, the draining efficiency can be raised and also the removal of offensive odors and the lowering of COD value can be attained.

Title: Elastic material for water section
Inventor: KITAZAKI SATOSHI
IPC: B32B1/08
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To impart retention resistance, chemical resistance, water resistance and friction resistance without impairing physical properties such as mechanical strength and elongation by covering the surface of an elastic material with a coating layer containing fluorine set within a specified film thickness range. SOLUTION: A tube 1 for a pinch valve is manufactured, for example, using an ethylene propylene rubber, and a coating layer containing fluorine with 0.3-4 μm thickness is applied to cover both inner surface and outer surface of the tube 1 by a gas phase fluorine treatment. Thus it is possible to control the mutual retention of rubbers by applying the coating layer, and further suppress the qualitative deterioration of the rubber by hypochlorous acid contained in a tap water. In addition, the tube 1 does not show any durability change and the frictional resistance of the tube 1 is reduced, resulting in the ability to prevent the tube 1 from being worn out by a pressing member 2 by coating the outer face of the tube 1. Besides the resistance to retention of the elastic material can be enhanced by setting the coating layer within the specified range of thickness.
