Abstract: A fuel injection valve according to the present invention has an expanded portion formed in a first injection-hole plate on an upstream side, thereby allowing positional misalignment between injection-hole portions. As a result, a radial dimension between an inner diameter-side circumferential edge of an upstream-side injection hole outlet portion and an inner diameter-side circumferential edge of a downstream-side injection hole inlet portion is not required. Thus, a plate thickness of a second injection-hole plate on a downstream side can be kept to minimum. As a result, weldability between an injection-hole plate body and a valve seat is improved.

Abstract: Provided is a control method for a robot system including: working units; and a robot having unit related processes that include moving between two of the working units and executing work. The control method includes: determining, in a case of detecting a first working unit that has come into a work required condition, whether an operation of the robot is stopped on a way from a current position to a position of a second working unit; stopping the operation of the robot on the way if determining that the operation of the robot is stopped on the way; and selecting a unit related process corresponding to a working unit other than the first working unit, moving the robot until the robot arrives at a position, and stopping the operation of the robot at the position, if determining that the operation of the robot is not stopped on the way.

Abstract: A method of generating a spray by a fluid injection valve is provided. The fluid injection valve includes a valve seat (10), a valve body (8), and an orifice plate (11) having a plurality of orifices (12). The flows in the orifices and the flows directly below the orifices are configured to be substantially liquid film flows. The directions of jet flows (30), (31) from the respective orifices (12) are not necessarily matched to the central axis directions of the orifices and are not necessarily intersected with each other at a downstream position thereof. The sprays are caused to converge by the Coanda effect acting on a plurality of sprays after jet flows from the orifices (12) become sprays at a downstream position farther than a break-up length (a). The convergence of the sprays is continued until the Coanda effect is substantially lost.

Abstract: A spray gun including: a nozzle provided with a fixed-side restricting section; a needle valve inserted inside the nozzle and provided with a valve portion such that an aperture is formed radially therebetween; an elastic seal member that comes in contact and is elastically deformed in an axial direction between the nozzle and the needle valve; and a straight joint formed by a female joint provided on a nozzle hole of the nozzle and a male joint provided on the valve portion. The straight joint is arranged such that the male joint fits inside the female joint before the elastic seal member comes in contact between the nozzle and the needle valve as well as after the aperture becomes the smallest, and the jointed state is retained until the elastic seal member comes in contact and is elastically deformed therebetween.

Abstract: When injection-hole inlets and injection-hole outlets are projected vertically onto an X-Y plane (N) perpendicular to a valve-seat axial center, an injection-hole arrangement angle (A), which is formed by a straight line (a) passing through a center of the injection-hole inlet of a reference injection hole and the valve-seat axial center and a straight line (b) passing through a center of the injection-hole inlet of the injection hole neighboring the reference injection hole and the valve-seat axial center on the plane (N), is set so as to become smaller as being closer to a Y-axis. A fuel turn angle (a) on a wide-angle side, which is formed by the straight line (a) and a straight line (c) passing through a center of the injection-hole inlet and a center of the injection-hole outlet on the plane (N), has a relationship: 90°<?<180°.

Abstract: A shock absorber includes a cylinder portion, a piston rod portion arranged as a single member, a pair of protruding members protruding from an outer circumferential surface of the piston rod portion, and a piston valve assembly having the piston rod portion passing therethrough. The piston valve assembly includes a piston portion, a valve element, and a threaded portion arranged to extend or contract in an axial direction as a result of rotation of a female thread portion relative to a male thread portion. The piston valve assembly is arranged such that the piston portion and the valve element are retained to the piston rod portion so as not to move with respect to the axial direction of the piston rod portion by a stretching force generated between the pair of protruding members due to extension of the threaded portion.

The second rod portion has a stiffness lower than the stiffness of the first rod portion. When the first piston portion moves toward the one end portion side of the first cylinder portion, the first rod portion moves into the first cylinder portion so that the volume of the internal space of the first cylinder portion decreases, while the second piston portion moves along with the first piston portion so that the volume of the first chamber of the second cylinder portion increases.
