摘要:
A connector for a fuel tank includes a flange portion, an outer connecting portion to be connected to a pipe member and an inner connecting portion to be inserted into a fuel tank through a connecting opening of the fuel tank. The inner connecting portion has an engaging portion to be engaged with an engaged portion provided to a member when the member is to be disposed in the fuel tank. The flange portion includes an outer flange member made of a synthetic resin same as that of an outer surface of the fuel tank, and an inner flange member made of a synthetic resin having a gas barrier property and a rigidity higher than that of the synthetic resin constituting the outer flange member. The inner connecting portion and the inner flange member are made of the same material.

A fuel tank connector for connecting a fuel tank and a pipe in communicating fashion includes a gas barrier member made of a synthetic resin and having a gas barrier property. The gas barrier member includes a tubular portion and a flanged portion provided on a peripheral side of the tubular portion, which extends beyond an opening of the fuel tank. The gas barrier member is made of a liquid crystal polymer, aromatic polyamide, a blended polymer of an ethylene-vinyl alcohol copolymer and high-density polyethylene, a blended polymer of polyamide and polyethylene, a blended polymer of polyamide and high-density polyethylene.

A leak detecting system detects fuel gas leakage of a fuel tank. The detecting system includes a fuel pump, a jet pump, and a bent valve, which are disposed in the fuel tank. A fuel flow path system includes a relief line connected to the fuel pump for relieving an excess fuel, a relief flow path switching valve disposed in the relief line, and a sub-line for connecting the switching valve and the vent valve. An air flow path system includes a first air flow line to connect the vent valve to a canister, a second air flow line for connecting the first air flow line to the jet pump, and an air flow switching valve for switching communication between the first and second air flow lines. An inner pressure sensor is provided to the fuel tank for detecting an inner pressure of the fuel tank.
摘要:
A jet pump device includes more than two jet-pump portions formed of discharge nozzles for discharging surplus fuel relieved from a pressure regulator and outlets formed in front of the discharge nozzles. The jet-pump portions are arranged such that the discharge nozzles are situated inside a chamber and the outlets communicate with the chamber. The chamber is provided with a suction path for sucking fuel or air.

A process for condensation between at least one ≡SiOH unit and at least one ≡SiOR unit is provided. In accordance with the present invention, R=a hydrogen or a C1-C20 hydrocarbon group optionally comprising one or more heteroatoms, and the ≡SiOH and ≡SiOR units belong to at least one identical or different (organo)silicon compound P. The process is conducted in the presence of an effective amount of at least one catalyst C, comprising a carbene. Compositions are also provided.
摘要:
A droplet discharge method includes performing a plurality of scans in which a discharge head and a substrate are scanned relative to each other, discharging droplets of a plurality of types of functional liquid from the discharge head onto a plurality of prescribed portions on the substrate that are arranged in a matrix while the discharge head and the substrate are scanned. The discharging of the droplets includes discharging the droplets onto the prescribed portions over the plurality of scans so that centers of newly discharged droplets are made to land at one of positions that overlap with centers of landing positions of the droplets already discharged to the prescribed portions and positions that are offset in a row direction and in a column direction of the matrix from the centers of the landing positions of the droplets already discharged to the prescribed portions.

A method is provided to reliably form shot drops on all of a plurality of pixel areas. The method comprises a step of forming a plurality of shot drops by ejecting droplets from a plurality of nozzles of a drawing apparatus to a plurality of pixel areas on a substrate. The step of forming the plurality of shot drops includes a step of forming additional shot drops near predetermined ones of the plurality of shot drops.
摘要:
A discharge amount measurement method is configured to measure a discharge amount of a liquid discharged from at least one nozzle of a droplet discharge head. The discharge amount measurement method includes discharging the liquid as a droplet from the at least one nozzle of the droplet discharge head by a number of discharges that is set to obtain a measurable quantity by driving the droplet discharge head based on measurement discharge data that is substantially identical to data used when a drawing pattern is formed by discharging the liquid from the at least one nozzle of the droplet discharge head, measuring the discharge amount of the liquid discharged from the at least one nozzle of the droplet discharge head, and calculating an average discharge amount based on the discharge amount and the number of discharges.
