Abstract: PURPOSE:To obtain the subject compound by adding both hydroquinone and a hydrogen halide eliminator to a mixture of a polar aprotic solvent and aromatic hydrocarbon, making a reflux under heating and azeotropic dehydration followed by reaction of 2,3-dichloro-5-trifluoromethylpyridine. CONSTITUTION:Both hydroquinone and a hydrogen halide eliminator (e.g. potassium carbonate; at an amount of 0.10 to 0.70 equivalents based on hydroquinone) are added to a mixed solvent composed of a polar aprotic solvent and aromatic hydrocarbon (e.g. N,N-dimethylsulfoxide and xylene), and the resultant system is refluxed under heating at normal pressure to progress azeotropic dehydration. Thence, 2,3-dichloro-5-trifluoromethylpyridine (at an amount of 0.20 to 0.95 equivalents based on the hydrogen halide eliminator) is added to the resulting system followed by reaction at 100 to 170 deg.C, and the solvent is distilled away from the reaction mixture followed by addition of an acidic aqueous solution and then extraction with an aromatic hydrocarbon solvent, thus obtaining the objective compound. The present production process is industrially advantageous.

Title: Multivalve intake engine
Inventor: HORIUCHI SHIGEAKI
IPC: F02B31/02
Filed: 1999-04-21
Abstract: PROBLEM TO BE SOLVED: To eliminate intake interference within a cylinder and to aim at high swirling. SOLUTION: In this multivalve intake engine, a plurality of intake ports are provided per cylinder, the intake port of a swirl direction upstream side and the downstream side intake port of the intake ports are made into a helical port 2 and a tangential port, respectively, and a valve guide boss within the helical port 2 is eliminated.

IPC: E02D27/34
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To absorb earthquake energy when excessive overturning moment is applied to a building by arranging axial force bearing piles further outside piles positioned on the outer peripheral part of a building, and connecting the head parts of the piles on the outer peripheral corner parts to the head parts of the axial force bearing piles through hysteresis damping type foundation Piles. SOLUTION: A pile 3 group are positioned directly under a building 1, axial force bearing piles 4 are arranged outside the piles 3a on four corners, the head parts of the piles 3a on the outer peripheral corner parts and the head parts of the axial force bearing piles 4 are connected together through foundation piles 7. The axial force bearing piles 4 are bound with the ground, connected to the piles 3a directly under the building through the foundation piles 7, and hence when overturning moment is applied to the building 1, bending moment is applied to the foundation piles 7, and when excessive overturning moment is applied to the building 1, the foundation piles 7 reach yielding by this bending moment, and in this process earthquake energy is absorbed by hysteresis damping action. Consequently, earthquake input to the building 1 can be reduced.

Title: Reflection preventive film
Inventor: OGURA TOSHIAKI
IPC: G02B1/11
Filed: 1988-05-11
Abstract: PURPOSE:To improve the residual reflection factor, the adhesive strength to an optical glass element, and the durability by forming reflection preventive films of double-layer constitution on the surface of the optical glass element, and specifying the refractive index and optical film thickness of each layer. CONSTITUTION:The reflection preventive films 2 and 3 are formed in two layers on the surface of the optical glass element 1 formed by pressing an optical glass raw material which has a <=1.48 refractive index and a >=80 Abbe number. The 1st layer 2 from the optical glass element 1 uses a high-refractive-index oxide dielectric whose refractive index is 1.90-2.40, and its optical film thickness is 0.05-0.25lambda0. Further, the 2nd layer uses a low-refractive-index dielectric whose refractive index is 1.35-1.50 and its optical film thickness is >=0.25lambda0. Consequently, the residual reflection factor, the adhesive strength to the optical glass element, and the durability are improved.

Title: Production of substrate with fine pattern
Inventor: MATSUNO YOSHIHIRO
IPC: G02B5/18
Filed: 1991-04-18
Abstract: PURPOSE:To form fine rugged patterns of prescribed sizes on a substrate by executing the formation of a coating film and the joining and pressing of a pressing mold in an atmosphere of <=50% relative humidity. CONSTITUTION:Since the formation of the coating film 2 and the joining and pressing of the press mold 3 are executed in the low-humidity atmosphere (<=50% relative humidity), the polycondensation reaction rate or crosslinking reaction rate of a metal org. compd. is suppressed and the curing rate of the coating film 2 decreases. The time having a proper viscosity in the pressing operation is prolonged without incorporating a thickener or incorporating the thickener at a low ratio therein into the coating liquid. In addition, the patterns of the coating film 2A with the patterns are formed with the good reproducibility of the shapes. Further, the shrinkage of the coating film 2 arising from the combustion of the thickener does not arise at the time of heating and calcining of the coating film 2A with the patterns and, therefore, the formation of the patterns having the prescribed shapes with good dimensional accuracy is possible.

Title: Method and apparatus for sucking powder and particle for pneumatic conveyance
Inventor: NAWATA SHINSUKE
IPC: B65G53/52
Filed: 1981-07-21
Abstract: PURPOSE:To prevent powder and particles from remaining and stagnating in a duct, by allowing the powder and particles to be sucked through slits in the right and left sides of a hopper bottom into the air duct for transportation. CONSTITUTION:The air ducts C1, C2 for transportation are formed using the side plates 1a, 1b of the successively arranged in hoppers A, and air under negative pressure is passed through the air ducts C1, C2. The slits B1, B2 are formed in the lower parts of the side plates 1a, 1b of the hopper A. The powder and particles stored in the hopper A are admitted through the slits B1, B2 into the air ducts C1, C2. In this case, since the slits B1, B2 extend in opposite directions, inflow interference of the proceeding air will occur, and the powder and particles will hardly enter the transporation air ducts C1, C2. Therefore, by providing a baffle D at a position between the slits, the inflow interference can be prevented.
