摘要： PURPOSE:To obtain a fuel absorber having superior durability and evaporated fuel capturing ability by allowing an org. high molecular compd. having fuel capturing function to react with a cross-linking agent in a soln. of a dispersant and granulating the resulting fine particles of polymer gel. CONSTITUTION:An org. high molecular compd. having fuel capturing function such as PP or PE is dissolved in a solvent such as benzene or toluene and the resulting soln. is added to a soln. contg. a dispersant such as PVA or gelatin under stirring. A reaction is allowed to take place in the presence of a cross- linking agent such as benzoyl peroxide. After the end of the reaction, fine particles 50 of polymer gel are collected and granulated without removing the dispersant 52 sticking to the particles 50 to obtain a fuel absorber 5 having superior durability to the cycle of absorption and desorption and superior evaporated fuel capturing ability.

摘要： PURPOSE:To obtain a fuel absorbing body which possesses the superior fuel absorbing faculty and absprption/desorption durability and can be shaped to arbitrary shapes such as fiber and sheet forms. CONSTITUTION:A fuel absorbing body is made of the high molecular material which is formed through the cross-linking reaction under the condition free of solvent, and has a toluene swelling degree of 500wt.% or more and a toluene- insoluble portion of 70wt.% or more. In the manufacture, the polymer such as EPDM and EVA and a cross-linking agent are dissoved previously into the solvent at a temperature close to the normal tempeature. Then, the solvent is evaporated, and the state free of solvent is generated. Then, cross-linking reaction is carried out by heating.

摘要： PURPOSE:To provide a flow changeover valve with a simple structure and a low cost which can make purge adjustmeal so that no great amount of evaporated fuel may enter into an engine intake pipe. CONSTITUTION:A changeover valve body 3 is installed between an absorption chamber 21 filled with organic polymeric gel 4 and a space chamber 22. The absorption chamber 21 is comminucated with a fuel tank 9 and the space chamber 22 is comminucated with an engine intake pipe 5 through plural purge ports 271-273. When the organic polymeric gel 4 absorbs a great amount of evaporated fuel, the changeover valve body 3 is pushed by the expansion force so that a part of purge ports can be closed. Therefore, in purge operation, the flow rate of purge air becomes smaller and no great amount of separated and evaporated fuel flows into the engine intake pipe 5 from the organic polymeric gel 4. When the absorption amount of the evaporated fuel is small, an expansion amount is small and many purge ports are opened.

摘要： PROBLEM TO BE SOLVED: To control rotation of a rotator easily to a target rotational state in feedback control. SOLUTION: During feedforward control of a motor B, rotational position of motors A and B is detected and then the rotational speed is detected from the rotational position thus detected (72). Positional error Δθ p is detected from the rotational position of the motors A and B and speed error Δω is detected from the rotational speed of the motors A and B (74). The ratio δ of the positional error Δθ p and the speed error Δω is operated (76). A decision is made whether the δ falls within a predetermined range where a rotational state can be feedback controlled to a target state without inverting the sign of torque during feedforward control (78). If the δ falls within the predetermined range, a maximum torque is estimated (80) and switching is made to feedback control (84, 86) if the estimated maximum torque falls within an allowable range (82; Y).

摘要： PROBLEM TO BE SOLVED: To perform a dechlorinating treatment of waste resin materials, excellent in practicality and capable of removing chlorine from the waste materials containing chlorine without generating chlorine gas by passing through a process of treating the material in a supercritical water. SOLUTION: This method for dechlorinating waste resin materials containing chlorine comprises a process of adding a basic compound (e.g.; calcium hydroxide) into the waste resin materials containing chlorine with melting and kneading, and a process for treating the mixed and kneaded material in a subcritical or a critical state water. Further, as the above-mentioned waste materials, car shredded dusts can be used and it is preferable to set a temperature in the above mixing and kneading at 300 deg.C and

摘要： PROBLEM TO BE SOLVED: To obtain a polyurethane resin powder in which the crosslinking bonds are partially cut so that active groups are exposed on the surface of the particle and realize the recycling of the powder by hydrolyzing and shearing a waste polyurethane bumper material in the presence of moisture. SOLUTION: This crosslinked polyurethane resin powder is produced by a process suitable for the material recycling (reuse for a filler, a sound absorbing material, a vibration-dumping material, and a substitute material for a rubber component) of a waste bumper material of polyurethane resin. A rigid or semirigid polyurethane resin from a waste bumper material is kept at a temperature higher than the hydrolyzing temperature of the resin and lower than the liquefying temperature thereof in the presence of moisture and subjected to shearing at the same time or subsequently to form a powder, thus giving a crosslinked polyurethane resin powder in which the crosslinking bonds are partially retained and partially cut and of which the resultant active groups are partially exposed on the surface of the particle. The raw material used in this process preferably comprises a resin obtained by reaction injection molding from a hydroxy compound, an isocyanate compound and a crosslinking agent as the principal constituents.
