  • Patent number: 9711819
    Abstract: A mount structure includes a mount member, and a bracket member. An upper surface of the bracket member, which is connected to a lower portion of a fuel cell stack, includes an upper surface cut formed by cutting the bracket member in a depth direction, and the upper surface cut extends in a surface direction. A lower surface of the bracket member, which is opposite to the upper surface, includes a lower surface cut formed by cutting the bracket member in the depth direction, and the lower surface cut extends in the surface direction.

  • Patent number: 9180914
    Abstract: A support structure for a vehicle is interposed between a vehicle body and a vehicle part and is connected with fastening members to support the vehicle part. The support structure is made of a non-ferrous light alloy. Among connecting surfaces of the support structure to which the vehicle body and the vehicle part are connected, an electrochemical corrosion inhibitor is applied to a connecting surface that is located on a lower side, in a vertical direction of the vehicle, of one of the vehicle body and the vehicle part. The one of the vehicle body and the vehicle part corresponds to the applied connecting surface.

  • Patent number: 8501204
    Abstract: A vesicle is produced by: a step of producing a W/O emulsion from an aqueous solution containing a substance to be entrapped in a vesicle in a dissolved or suspended state and an organic solvent phase containing a lipid having emulsification capacity, which can constitute the vesicle; a step of producing a W/O/W emulsion from the W/O emulsion and an external water phase solution of a water-soluble emulsifier, which does not destroy a vesicle lipid membrane; and a step of removing the organic solvent phase from the W/O/W emulsion, so as to form a vesicle. This method simultaneously achieves a high entrapment yield of an active ingredient and the control of a particle diameter.

  • Patent number: 8246868
    Abstract: A W/O emulsion is produced from an aqueous solution containing a substance to be entrapped in a vesicle in a dissolved or suspended state and an oil phase containing an emulsifier; subsequently, the W/O emulsion is cooled to a temperature at which the aqueous solution of the W/O emulsion becomes a frozen particle and the oil phase maintains a liquid state, and the oil phase is removed; thereafter, an oil phase containing a vesicle constituent lipid is added to the frozen particle, and the obtained mixture is then stirred, so as to substitute the emulsifier on the surface of the frozen particle with the vesicle constituent lipid; and thereafter, an external Water phase is added to the frozen particle coated with a lipid membrane, so as to hydrate the lipid membrane by the external water phase. This process achieves a high entrapment yield of a desired substance while controlling desired physical properties such as particle diameter.

  • Patent number: 6343627
    Abstract: An apparatus for supplying a semiconductor process gas charged in a large-capacity gas vessel to a plant where the gas is used, after reduction of the pressure of the gas. The gas cylinder 21 is composed essentially of a cylindrical portion 22 and hemispherical portions 23 and 24 formed at the ends of the cylindrical portion respectively. The gas cylinder 21 has a gas charge port 26 at one hemispherical portion and a gas discharge port 27 at the other hemispherical portion both of which opening in alignment with the axis 25 of the cylindrical portion 22. A charge valve 28 and a gas discharge unit 29 having at least a gas vessel valve 30 and a pressure reducing valve 32 are connected to the gas charge port and the gas discharge port respectively. The gas cylinder 21 is housed together with the charge valve 28 and the gas discharge unit 29 in a container 36.

  • Patent number: 4184465
    Abstract: A fuel injection device is disposed in a fuel supply passageway and adapted to control the amount of injection by controlling the opening time and/or opening area of a gate controlled in connection with engine rpm and the amount of suction air. The difference between the fuel supply pressure and the negative pressure in a suction pipe is maintained constant by a pressure regulator. The device contains a mechanism for compensating fuel supply pressure according to fuel temperature.
