  • Patent number: 10934897
    Abstract: Provided is a mechanical lash adjuster including a plunger, a housing put into thread engagement with the plunger in an axial direction to form a thread engagement portion, the plunger engaging member fixed and retained in a circumferential direction of the thread engagement portion, and a coil spring urging the plunger in a direction opposite to a urging-force acting direction of a coil spring. A lead and flank angles of threads forming the thread engagement portion are set such that when an axial load acts on the plunger in either of a plunger extension and contraction directions, the plunger is made self-sustaining, and when the plunger swings by an amount corresponding to a backlash due to a lateral load, the plunger slides and rotates at the thread engagement portion to move in an axial-load acting direction.

  • Patent number: 10173257
    Abstract: A method of machining a screw is provided that is capable of preventing formation of a protruding section at a thread tip section. A thread is formed by cutting on a cylindrical body, and a surface of the thread is plastically deformed by rolling. Because of the cutting, a width between-side surfaces of a thread tip section is in a narrowed state as compared to a normal width. This width is narrowed toward a tip of the thread while a thread body section has a width expanded as compared to a normal width. Consequently, the side surfaces are formed to bulge by an excess thickness portion as compared to normal side surfaces. The rolling plastically deforms both side surfaces to cause the excess thickness portion to plastically flow toward the side surfaces.

  • Patent number: 9995029
    Abstract: To provide a flush toilet in which: a circulating flow can be formed to uniformly circulate over a waste receiving surface while flushing; localized changes in external appearance of a toilet main body can be inhibited; and impression of a left-right symmetrical external shape can be conveyed to users so that design characteristics thereof are favorably preserved. A rim portion in a flush toilet includes a slit opening portion formed between an upper edge portion of the waste receiving surface formed to be left-right asymmetrical and a rim inside wall formed to be left-right symmetrical. The slit opening portion is formed such that a slit gap on one side, to which a connecting water conduit is directed, is smaller than a slit gap on the other side. A circulating flow is formed on the waste-receiving surface by flush water spouted from the slit opening portion having the different slit gaps.

  • Patent number: 9790822
    Abstract: With a poppet valve using a coolant, maximum combustion efficiency is realized by adjusting relative values of a heat insulation effect and a heat dissipation effect. From the inside of a head portion (14) to a stem portion (12) of a hollow poppet valve (10) a heat insulating space (S1) and a cooling portion (S2) loaded with a coolant (19), separated from each other by a partition (15), are formed. By properly setting an installation position and a vertical length of the partition (15) according to a type of vehicle for which the valve is used, appropriate heat insulation effect and heat dissipation effect are obtained. Further, by the partition (15), mechanical or thermal strength of the poppet valve in which the heat insulating space (S1) and the cooling portion (S2) are formed is increased.
