  • Patent number: 8717941
    Abstract: In a communication system including a MN, a MFA connected to the MN, and a HA connected to a home network of the MN, the HA holds a layer 3 address of the HA and a source layer 3 address of a registration request by associating them with each other. The MFA transmits a layer 2 frame from the MN to the HA by encapsulating it. The HA decapsulates the frame to transmit it to the home network. When the HA receives a layer 2 frame from the home network, the HA checks that the destination layer 3 address is registered, and encapsulates the layer 2 frame to transmit it to a source layer 3 address of the registration request that is registered being associated with the destination layer 3 address. The MFA decapsulate the encapsulated layer 2 frame to transmit the layer 2 frame to the MN.

  • Patent number: 8162162
    Abstract: The object of this invention is to provide a container having a reduced area of vacuum-absorbing panels and thus acquiring improved appearance and having strength against a pressure drop, i.e., the strength enough to retain the shape of the container even when there is a pressure drop inside the container. A shoulder portion or a bottom portion of a resin-made storage container is molded by aligning one or two groups of three corners and one or two groups of three pillars vertically and in parallel to the central axis of the container. Each group of three corners is a part of the corners forming a cross-section of a regular enneagon and being connected to either the shoulder portion or the bottom portion, and the lines connecting these three corners form a regular triangle. Each group of three pillars is a part of the pillars belonging to the body and forming a cross-section of a hexagon, and the lines connecting these three pillars form a regular triangle.

  • Patent number: 6217303
    Abstract: An orbiting fluid machine has a feature that the speed of sliding movement is low, while vibrations are small, its performance is lowered when the rotational speed becomes high, and this problem is resolved by the following structure. A displacement fluid machine includes a displacer making an orbital motion within a casing into which a working fluid is drawn, thereby drawing and discharging the working fluid, in which an oil retaining mechanism or a seal mechanism is provided at each of opposite end surfaces of the displacer. This results that, axial gaps at the end surfaces of the displacer are effectively sealed so as to reduce a leakage loss, thereby achieving a high performance and a high reliability.

  • Patent number: 6213743
    Abstract: A conventional displacement type fluid machine is featured by a low sliding rate and in low vibrations and pulsations, but has a problem, that the radial gap in a displacer sliding portion is enlarged by the clearance of a shaft drive system and a rotating moment acting on a displacer so that the internal leakage of a working fluid is increased to lower the performance and the reliability. To eliminate this problem, the sliding contact portion between a cylinder 4 and a displacer 5 is made into a predetermined section, and the cylinder and the displacer are so contoured that when they are made concentric, the normal distance in the sliding contact section between the cylinder contour and the displacer contour may be smaller than that of the remaining section, thereby to decrease the radial gap to lower the internal leakage of the working fluid and to improve the performance and the reliability.

  • Patent number: 6183228
    Abstract: A displacement type fluid machine in which a displacer and a cylinder are disposed between end plates, a space is formed by an inner wall surface of the cylinder and an outer wall surface of the displacer when the center of the displacer is put on the center of the cylinder, and a plurality of spaces is formed when the positional relationship between the displacer and the cylinder is for a gyration, is restrained from deterioration of the efficiency. One of the end plates and a vane protruding inwardly from the inside surface of the cylinder are fixed to each other so as to restrain the deformation of the vane and decrease the leakage of a working fluid due to the deformation.
