  • Publication number: 20220324515
    Abstract: An automobile suspension includes a side rail extending in a front-rear direction of a vehicle body, a lower arm, and a bracket linking the lower arm to the side rail. A front end of the side rail and a rear end of the side rail are linked to a frame of the vehicle body, and the side rail curves such that a middle of the side rail is lower than at least one of the front end and the rear end. The bracket includes a pair of side plates that supports a shaft of the lower arm and is joined to a side face of the side rail, and an upper plate that links the side plates and is joined to an upper face of the side rail.

  • Patent number: 11084535
    Abstract: A gusset is joined to an instrument panel reinforcement and a floor brace. The instrument panel reinforcement includes a D seat rear beam extending from a portion to be joined to the floor brace to a portion for supporting the steering column. The D seat rear beam includes a D seat upper beam having a hat-shaped cross section open toward a lower side. The gusset includes a reinforcement joint portion that is joined to the D seat upper beam to form a closed cross section.

  • Publication number: 20200078863
    Abstract: A metal additive manufacturing method includes designing a support part for supporting the shaped object in the shaped object, performing a metal additive manufacturing analysis on the shaped object in a state in which the support part is formed, detecting a part of the shaped object where residual stress becomes greater than a predetermined value based on a result of the metal additive manufacturing analysis, designing a heat path part to be brought into contact with the part where the residual stress becomes greater than the predetermined value, performing the metal additive manufacturing analysis on the shaped object in a state in which the support part and the heat path part are formed, and performing a shaping process so that the designed support part and the designed heat path part are formed.

  • Patent number: 4141643
    Abstract: A photoconductive drum or sheet is movable relative to a developing electrode which is biased to a voltage which prevents smearing of the background areas of the copy. A sensing electrode is disposed upstream of the developing electrode in the direction of movement of the drum or sheet which senses the voltage on the drum or sheet. The sensing electrode is provided in a plurality of independent segments, and a computing circuit selects the voltage on the segment which is lowest in magnitude and which corresponds to a background area of the copy and applies the biasing voltage to the developing electrode in dependence on the sensed voltage. An auxiliary electrode is provided so that the combination of the sensing electrode and the auxiliary electrode is coextensive with the drum or sheet in a direction perpendicular to the movement thereof to prevent streaking of the copy.
