Abstract: A neuromuscular disease evaluation device that is less invasive, highly sensitive, quantitative and objective, and capable of easily evaluating neuromuscular diseases. A device for evaluating motor functions related to neuromuscular diseases, comprising: a memory unit storing a reference value for evaluating a predetermined movement, which is calculated based on a position of at least one body part; an analysis unit for identifying a position of a body part of the user by analyzing information based on an image captured of the predetermined movement, including the user's body; and an evaluation unit for evaluating the motor function based on the numerical value calculated based on the position of the body part of the user and the reference value.

Abstract: A fuel injection valve includes: a holder which accommodates a valve body, has a surface magnetically facing the outer periphery of an armature, and is joined to a core; a housing which is press-fitted onto the outer periphery of the holder and accommodates a coil; and a cap which covers the fuel upstream side of the coil in a lid shape and is press-fitted onto the outer periphery of the core. The lower surface of the cap is brought into contact with the upper end surface of the housing in a radially slidable state and then an outer peripheral portion of a contact surface between the cap and the housing is joined by laser welding.

Abstract: A holder of a fuel injection valve is press-inserted to a housing of the fuel injection valve so as to be fixed to the housing, a cap of the fuel injection valve includes a notch portion for notching an annular portion, and is arranged in such a way that an inner circumference surface of the cap is faced to an outer circumference surface of a core of the fuel injection valve via a gap, and an electrode terminal of the fuel injection valve is connected to a terminal of a solenoid of the fuel injection valve via the notch portion of the cap.

Abstract: In a fuel injection valve, a bobbin includes a bobbin main body serving as a part around which a coil is wound, and a terminal housing portion projecting upward from a part of a circumferential direction of the bobbin main body. The terminal housing portion is exposed to the exterior of a cap. A terminal is inserted into the terminal housing portion and electrically connected to the coil. A gap is provided between the core and a housing portion inner surface serving as a core side surface of the terminal housing portion. Resin used to form the connector mold penetrates the gap.

Abstract: A fuel injection valve includes a valve seat which has a valve seat surface, an injection nozzle having an inclined axis center, and a conically-shaped tapered surface located between the valve seat surface and the injection nozzle; and a valve element for controlling fuel supply to the injection nozzle. One part of an opening of the injection nozzle is connected to the tapered surface; the other part of the opening is connected to the valve seat surface; and a relationship between an angle ?1 formed by the injection nozzle and the tapered surface at an area where the injection nozzle is connected to the tapered surface side, and an angle ?2 formed by the injection nozzle and the valve seat surface at an area where the injection nozzle is connected to the valve seat surface side is configured to be ?1??2.

Abstract: A return spring assembly for use in an engine intake throttle valve return device comprising a spring holder sleeve (17) including an inner and outer sleeves (18,20) placed over a throttle valve shaft (3) and connected at one end to each other so that the inner and outer sleeves (18,20) are spacedly and concentrically held. Inner and outer torsion coil springs (8,9) are supported on the inner and outer sleeves (18,20), respectively, and connected between an intake barrel (1) and the valve shaft (3) for urging the throttle valve (2) to its closed position. An eccentric radial flange (22) which may be circular, oval or polygonal is provided on the outer sleeve (20) for holding the outer torsion coil spring (9). The eccentric flange (22) extends continuously over the entire circumference of the outer sleeve (20) and has a maximum outer diametrical dimension substantially equal to the inner diameter of the outer torsion coil spring (9).
