  • Publication number: 20020072891
    Abstract: Disclosed is a method for setting analysis conditions for multi-physics analysis for analyzing an object model with a plurality of different types of physical simulation models. The method comprises the step of; setting the physical models for element groups constituting the object model; searching boundaries in the object model corresponding to the set element groups; reflecting the physical models of the element groups at the boundaries on a screen for setting analysis conditions for the boundaries; and setting analysis conditions for the boundaries on the screen for the reflected boundaries. Using the principle that a group and the boundaries of that group share the common properties of a physical model, the boundaries corresponding to a group are automatically searched and its analysis conditions are set on a screen when the physical models are set, so that the correlation between the group and the boundaries is reflected on a screen.

  • Patent number: 6112711
    Abstract: A valve performance control apparatus has a low speed cam, a high speed cam, and an intermediate speed cam. A rocker arm is arranged between the cams and a valve. The rocker arm contacts the low speed cam. A pair of cam followers are reciprocally supported in the rocker arm to contact the high speed and intermediate speed cams. Lock members are slidably received in bores (or grooves) of the rocker arm. The lock members, when positioned in an unlocked position, permit the free reciprocation of the associated cam followers with respect to the rocker arm, which causes the valve to be driven by the low speed cam. When locked, the lock members abut against the associated cam followers and lock the cam followers to the rocker arm, which causes the valve to be driven by the cam with the largest profile. The lock member has an abutment surface, which contacts and is pressed by the cam follower.

  • Patent number: 6082104
    Abstract: An exhaust manifold has inner and outer tubes made of stainless steel and welded to flanges provided at inlet ports of the exhaust manifold, from which exhaust gas discharged from an engine enters the exhaust manifold. The inner tube has flat portions, and shield plates disposed within the inner tube protect the flat portions from being directly vibrated by pressure waves of the exhaust gas. Accordingly, the vibration of the flat portions is lowered, so that high frequency noise from the exhaust manifold is reduced.

  • Patent number: 5904226
    Abstract: An engine has a crankshaft, a combustion chamber and a valve that selectively opens and closes the combustion chamber. The valve has a timing relationship to the crankshaft and lift characteristic. A control device hydraulically alters at least one of the timing relationship and the lift characteristic. A lubricant passage is connected with the control device to supply oil to a mechanism that is formed by engine parts slidably contacting one another within the engine. An auxiliary passage is provided for supplying the oil to the mechanism. Oil supplied from an oil pump to said auxiliary passage is restricted by an electromagnetic valve that is actuated based on the instruction from an electric controller when engine speed is lower than a predetermined value.

  • Patent number: 5813376
    Abstract: An engine has a crankshaft, a combustion chamber and a valve. The valve opens and closes the combustion chamber. The valve has a lift characteristic that is altered by a control device according to a change of hydraulic pressure therein. The engine has a lubricant passage that is connected with an oil pump and supplies oil to a mechanism formed by parts slidably connecting one another within the engine. A hydraulic pressure passage extends into an interior of the control device to exchange the hydraulic pressure with the control device, thereby the control device is actuated to alter the lift characteristic. The oil pump supplies the oil to the pressure passage when connected with the pressure passage. The oil pan supplies the oil to the pressure passage when connected with the pressure passage. A switching valve selects one of the oil pump and the oil pan to connect the selected one with the control device based on the engine speed.

  • Patent number: 5695865
    Abstract: In an automotive upholstery component including a trim main body and an ornamental sheet mounted on a selected part of the surface of the trim main body, the ornamental sheet is attached to the trim main body without using a bonding agent so that the fabrication steps may be reduced in number, the working environment may be improved, and the design characteristics of the product may be enhanced. A door trim main body is placed on an upper die for pressing which is equipped with a welder upper electrode, and the ornamental sheet is placed on the lower die for pressing which is equipped with a welder lower electrode. High frequency electric current of a prescribed voltage is applied across the upper and lower electrodes so that the ornamental sheet may be attached to a prescribed part of the surface of the door trim main body 20 over the entire area of the ornamental sheet, and the use of a bonding agent may be thereby abolished.

  • Patent number: 5436065
    Abstract: A strip of webbing for seat belts includes webbing woven from multi-filament threads made from synthetic fiber, and a mixture of acrylic resin and silicone impregnated into and fixed on the surface of the webbing. The webbing is deteriorated less in the anti-wear property and the smoothness because the acrylic resin is dissociated less by light so that it can hold the silicone on the surface of the webbing for a longer period of time. Thus, the webbing can produce a seat belt exhibiting an excellent accommodatability.
