A fuel tank for a vehicle is formed of a tank main body in which an upper tank and a lower tank are mutually joined to form a closed space in which fuel is housed, and a sub-tank fixed to a bottom surface part of the lower tank by spot welding, in which a plurality of rows of the spot welding are set along a longitudinal direction of the lower tank with an interval therebetween in a width direction of the sub-tank, at least one bead positioned between the rows of the spot welding and extending continuously along the longitudinal direction of the lower tank is formed on the bottom surface part of the lower tank, and a lower surface of the sub-tank has no portion that is not brought into contact with the bottom surface part of the lower tank except for the bead.
摘要:
To introduce a mixture to be processed, in which powder and granular material with relatively large specific gravity and hardness and accompanying lightweight foreign substances are mixed together, inside a system and separate the same by a dry method.Disclosed is a powder and granular material separation processing device X that is connected to an external suction machine such as a dust collection device and an electric vacuum cleaner, introduces by suction a mixture to be processed into a separation processing container 1, and discharges lightweight foreign substances to the outside of a system while collecting powder and granular material inside the system. The separation processing container 1 has a suction introduction tube 2 that is attached and sealed as the upper part structure of a hopper tank 4 that collects and stores the powder and granular material and receives the mixture to be processed on the circumferential surface thereof, and a suction discharge tube 3 that is connected to an external suction machine on the upper surface thereof. In addition, the separation processing container 1 has a separation cone 11 with a funnel-shaped bottom surface and a cylindrical opening 13 that hangs in a protruding shape downward from the tip part of the separation cone 11 and of which the opening diameter thereof is reduced stepwise to have multiple steps. The suction discharge tube 3 has a multiple tube configuration at the tip part thereof in which each tube is given a small diameter corresponding to each opening diameter of the cylindrical opening 13 to be loosely inserted and face the tip part of an opening.

Angle sensor device has magnetic force detectors detecting alternation of magnetic force caused by rotation of a throttle gear. The magnetic force detectors are buried in a molded body of the angle sensor device constructed of foamed resin. The magnetic force detectors each has a sensing unit detecting alteration of magnetic force and a computing unit computing based on signals from the sensing unit and outputting signals depending on the alteration of magnetic force and is formed in L-shape. Two of the magnetic force detectors are placed opposite each other such that one of the sensing units is disposed on the other sensing unit. The molded body has a cavity surrounded by the magnetic force detectors.

摘要:
A shoe midsole using a plastic material having flexibility, repulsion, and restoring characteristics and capable of instantaneously absorbing and damping an impact from every direction. The plastic material, which has flexibility and restoring characteristics, is used as the material of a body of the shoe midsole. The thickness of the body is set to a range from 1.5 mm to 3.0 mm. The body is formed in a shape that can control the arch of the foot. A heel section provided with a U-shaped edge and made of a plastic material is formed on the underside of a heel section of the body so as to be integral with the body. A continuous groove is provided in a region continuing from a side surface of the U-shaped edge of the heel section to the lower surface of the heel section of the body.
摘要:
It is intended to provide a drug which is efficacious against pathological conditions relating to arginine-vasopressin V1b receptor. More particularly speaking, it is intended to provide a drug which has a therapeutic or preventive effect on depression, anxiety, Alzheimer's disease, Parkinson's disease, Huntington's chorea, eating disorders, hypertension, digestive diseases, drug addiction, epilepsy, brain infarction, brain ischemia, brain edema, head injury, inflammation, immune diseases, alopecia and so on. As the results of intensive studies, a novel 1,3-dihydro-2H-indol-2-one compound and a pyrrolidin-2-one compound fused with a heteroaromatic ring, which are highly selective antagonists of arginine-vasopressin V1b receptor, have high metabolic stabilities and show favorable brain penetration and high plasma concentrations, are found, thereby achieving the above objective.
