Provided is an active energy ray curable composition cured by irradiation of active energy rays. The active energy ray curable composition contains an (A) radical polymerizable compound, a (B) photopolymerization initiator, and a (C) amine compound. The (B) photopolymerization initiator includes a (B1) sulfur compound and a (B2) acyl phosphine oxide compound. The (B1) sulfur compound is at least one of a sulfone compound and a thiobenzoyl compound.

Active energy ray curable composition

This invention forms a good unrepellent uniform coating film and an image having neither image missing nor image blur by using an inkjet printing method. Active energy ray curing inkjet ink contains (A) an active energy ray curing monomer and/or an active energy ray curing oligomer, (B) a photopolymerization initiator, and (C) a surface tension adjusting agent, and has a viscosity of 3.0 to 6.0 mPa&#xb7;s at 35&#xb0; C.

Active energy ray curing inkjet ink, printed product, inkjet printing apparatus, and inkjet printing method

A shock absorber includes a valve disc defining two chambers, a flow passage formed in the valve disc, the flow passage allowing communication between the two chambers, a window formed in the valve disc, the window being connected to the flow passage, a valve seat formed on the valve disc, the valve seat surrounding the outer periphery of the window; and a plurality of leaf valves formed in the shape of annular plates, the plurality of leaf valves being stacked on the valve disc. The first leaf valve stacked on the valve disc is provided such that an outer peripheral part is seatable on and separable from the valve seat, and includes a rib recessed on a valve disc side and projecting on an opposite valve disc side at a position facing the valve seat.

Shock absorber

A damping valve includes a piston, a damping passage, a piston rod, a bypass, and a relief valve, and the bypass includes a valve hole extending in the axial direction of the piston rod and a horizontal hole opening from a side part of the piston rod and leading to the valve hole, and the relief valve includes an annular valve seat provided on the side of a pressure side chamber with respect to an opening of the horizontal hole, a valve body slidably inserted on the side of an extension side chamber with respect to the annular valve seat and partitioning a back pressure chamber in the valve hole, a bias spring biasing the valve body toward the annular valve seat, and a throttle communicating the back pressure chamber with the extension side chamber.
