摘要： PROBLEM TO BE SOLVED: To provide an evaporated-fuel treatment device capable of easily discharging evaporated fuel from a fuel tank into a canister while a fuel is supplied into the fuel tank.
SOLUTION: When an internal combustion engine is stopped, and a cap is removed from an oil filler port 33 and the fuel is supplied into the fuel tank 32, an ECU 70 detects the variation with time of the voltage detected by a level gauge 66, and determines whether the oil is supplied or not into the fuel tank 32. When the ECU 70 determines that the oil is supplied into the fuel tank 32 based on the voltage detected by the level gauge 66, turns on the power to a pump 50 to generate a fluid flow on the filter 52 side of the canister 34. Then, a back pressure chamber 48 is depressurized through a back pressure passage 112, a diaphragm 46 is displaced in the direction that communicates the canister port 45 of an oil supply valve 40 with a tank port 44, and the oil supply valve 40 is opened. The evaporated fuel produced in the fuel tank during the oil supply passes through a passage 100 and the oil supply valve 40 and immediately sucked into the canister 34.

摘要： PROBLEM TO BE SOLVED: To obtain a position detection sensor 1 with high detection accuracy even when electric signals output from a magnetic field formed from magnets 2, 3 as a movable element, and magnetic field detection means 4, 5 as a stator vary with temperatures. SOLUTION: The position detection sensor 1 has swelling portions 6, 7 swelling in an arc shape in a lateral direction, the two magnets 2, 3 displacing in a longitudinal direction, and the two magnetic field detection means 4, 5 that detect the magnetic field formed from the magnets 2, 3. Both of the magnets 2, 3 are polarized in the longitudinal direction, and one edge side forms an S pole, and the other side forms an N pole. Besides, the magnetic field detection means 4, 5 are disposed at a predetermined clearance in the longitudinal direction. The clearance is one seconds of a cycle d of a trigonometric function if correlation characteristics between the coordinate in the longitudinal direction and flux density of the magnetic field formed at an air gap is taken as the trigonometric function. Thus, the position detection sensor 1 with high detection accuracy is obtained irrespective of temperatures. COPYRIGHT: (C)2010,JPO&INPIT

Namely, a first seal part 17 is formed in between the first conductive part 11 of the pair of conductive members 7, having no insulating cover, such as, an insulating film and the casing 4 so that the fuel flow-out path where the alcohol mixing fuel pressurized by the fuel pump leaks from the inside of the fuel tank to the outside of the fuel tank is eliminated.

摘要： PROBLEM TO BE SOLVED: To provide an exhaust gas recirculation device capable of efficiently mixing high temperature exhaust gas and low temperature exhaust gas. SOLUTION: As a valve element of an exhaust gas mixture ratio control valve 5 for adjusting a mixture ratio of high temperature exhaust gas and low temperature exhaust gas, a flap type valve 7 in which a normal with respect to the valve end face is inclined at a predetermined inclination angle with respect to a rotational center axis line of a valve shaft 8 is used. Due to this, the low temperature exhaust gas introduced from an EGR gas cooler 3 side to inside of a mixing chamber 33 and the high temperature exhaust gas introduced from a bypass piping 4 side to inside of the mixing chamber 33 are contacted with the flap type valve 7 inside the mixing chamber 33 and mixed while swirling toward an outlet side flow passage 34. Accordingly, since the high temperature exhaust gas and low temperature exhaust gas are mixed efficiently, the temperature of exhaust recirculating gas introduced from an exhaust gas recirculation pipe to an intake side can be accurately controlled.

摘要： PROBLEM TO BE SOLVED: To provide a torque motor which increases torque without increasing a supply current. SOLUTION: Protrusion and recess formed on the inner peripheral wall of a stator core 20 are formed by protrusions 21a, 21b protruding toward the rotor 40 side and coil accommodating parts 22a, 22b formed in recessed types which wind and accommodate windings of coils 31, 32. The protrusions 21a and the coil accommodating part 22b, and the protrusion 21b and the coil accommodating part 22a are positioned in point symmetry setting a rotating shaft 100 of the rotor 40 as the center. The protrusions 21a, 21b protrude on the rotor 40 side, so that an air gap (d) formed by the protrusions 21a and a permanent magnet 42, and the protrusion 21b and a permanent magnet 43 is made small. As a result, large torque is generated with the same supply current, as compared with a stator core which is not provided with the protrusions 21a, 21b.

摘要： PROBLEM TO BE SOLVED: To provide a torque motor which can be assembled easily and has a smooth flat torque characteristic. SOLUTION: Outer peripheral circular arcs 42b and 43b of permanent magnets 42 and 43 are made off-centered from a rotor core 41 by a distance (d) and the thicknesses of the magnets 42 and 43 become larger towards both ends in the peripheral direction. The peripheral thicknesses of the magnets 42 and 43 and the eccentricities of the circular arcs 42b and 43b from the rotor core 41 are set so as to satisfy the relation, B1=B3=B2cosθ, where B1, B2, and B3 respectively represent the magnetic flux density in the radial direction at the central parts of the arcs 42b and 43b in the peripheral direction, the magnetic flux densities at the positions on the arcs 42b and 43b, in the direction of magnetization forming an angle θ with the center 60 of the rotor core 41 and the centers of the arcs 42b and 43b in the peripheral direction, and the magnetic flux densities in the radial direction at the positions on the arcs 42b and 43b in the peripheral direction which forms the angle θ with the central parts of the arcs 42b and 43b in the peripheral direction.

摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of defective operation of a valve element and lodging of a foreign matter by a method wherein a clearance is varied between during engine operation and during a stop of an engine. SOLUTION: A drive shaft 7 on which a valve element 6 is attached is rotatably supported through ball bearings 11 and 12, and axially moved by an axial gap between ball bearings 11 and 12. During operation of an engine, a negative pressure in an intake sir piper is exerted on a closing plate 6c of the valve element 6. Since the component of force of a negative pressure in an intake pipe is higher than a suction forced exerted between the core 19 of an electromagnetic coil device and a permanent magnet 16, a drive shaft 7 is moved to the right togetherwith of the valve element 6, and a clearance between the closing plate 6c and the wall surface 9c of a valve chamber 9 is decreased. Since, during the stop of an engine, a negative pressure in an intake pipe is rendered ineffective, a drive shaft 7 is moved to the left togetherwith the valve element 6 through a suction force exerted between the core 19 and the permanent magnet 16 and a clearance between the closing plate 6c and the wall surface 9a of the valve chamber 9 is decreased.
