  • Publication number: 20050167052
    Abstract: A plasma processing device able to positively enhance a process-gas exhaust efficiency in a processing region and restrict plasma leaking. A processing container of a magnetron type parallel plate plasma processing device has a separator for separating the inside of the processing container into a processing region and an exhaust region. The separator has a plurality of gas passage holes to establish communication between the processing region and the exhaust region, and includes a non-conductive member. A conductive member is disposed on a gas passage-side surface facing the gas passage holes. A voltage V is applied by a power supply to the conductive member so that the gas passage-side surface is at a potential higher than that of a processing-region surface.

  • Patent number: 6915760
    Abstract: The present invention provides a plasma processing apparatus having an electrode plate arranging therein, an upper electrode to which a dielectric member or a cavity portion is provided, a dimension or a dielectric constant of which is determined in such a manner that resonance is generated at a frequency of high-frequency power supplied to the center of the back side and an electric field orthogonal to the electrode plate is generated, and a susceptor as a lower electrode so as to be opposed to each other, in order to reduce unevenness of an electric field distribution on the surface of the electrode in a plasma processing using a high-density plasma capable of coping with further refinement.

  • Patent number: 6644726
    Abstract: In a vehicle rear body structure in which a muffler is disposed below a rear cross member disposed to extend transversely below a rear part of the body of a vehicle, a lower end portion 10 of the rear cross member 7 extends downwardly to substantially the same height of that of a lower end portion 4c of a rear bumper face 4a disposed rearward of the rear cross member. Accordingly, it is possible to prevent the generation of heat deformation by protecting from heat related effects from a muffler a lower end portion of a rear bumper which tends to easily heat deform.

  • Patent number: 6641153
    Abstract: The wheel suspension system is dimensioned and positioned so as to be contained within a fore-and-aft profile of the engine assembly so that the wheel suspension system which is considered to be too rigid to define a crush zone in case of a vehicle crash is contained within the profile of the engine assembly, and would not in any way reduce the crush zone of the vehicle body which is effective in absorbing the impact energy of a vehicle crash. A steering gear may also be too rigid to define a crush zone. The engine assembly normally projects toward the passenger compartment at upper and lower parts thereof. Therefore, to avoid the steering mechanism from reducing the effective crush zone, the steering gear unit may be placed so as to oppose the recess thus defined in the engine assembly.

  • Publication number: 20030062743
    Abstract: In a vehicle rear body structure in which a muffler is disposed below a rear cross member disposed to extend transversely below a rear part of the body of a vehicle, a lower end portion 10 of the rear cross member 7 is caused to extend downwardly to substantially the same height of that of a lower end portion 4c of a rear bumper face 4a disposed rearward of the rear cross member. Accordingly, it is possible to prevent the generation of heat deformation by protecting from heat effects from a muffler a lower end portion of a rear bumper which tends to easily heat deform.

  • Patent number: 6164700
    Abstract: In a pretensioner device for automatically increasing a tension of a seat belt in case of a vehicle crash which uses a piston and cylinder arrangement as a power generator, a spring member resiliently urges the piston assembly in the direction of actuation so that any play that may be present in each connecting potion of the path of power transmission can be eliminated. Therefore, collision between component parts at the time of activating the power generator can be prevented, and the loss of energy which could arise from such collision can be avoided. The piston assembly may comprise a piston main body slidably received in the cylinder, and a piston rod having a base end abutting an opposing end of the piston main body and a free end projecting out of the open free end of the cylinder while the cylinder is provided with an inwardly directed radial flange for preventing the piston main body from being projected out of the cylinder.

  • Patent number: 6039386
    Abstract: In a floor structure of a vehicle comprising: left and right side sills; a substantially flat floor panel extending between the left and right side sills; and a cross member for connecting the left and right side sills, the cross member comprises: left and right upper members which extend inwardly from the left and right side sills, respectively, and attached to a top surface of the floor panel with their opposing inward ends spaced from each other; and a lower member extending laterally across a part of a lateral length of the vehicle and attached to an under surface of the floor panel. In the above floor structure, an open space formed beside the lower member can accommodate external piping under the floor panel, and the floor surface can be substantially flat by placing front seats over the upper members. Thus, a floor structure is achieved in which the floor surface is substantially flat and the floor is placed at a lower position.
