Abstract: A liquid ejecting head includes a first flow path extending in a first axial direction between a supply port and a discharge port, and a nozzle that is provided to branch from the first flow path and that discharges a liquid along a second axial direction orthogonal to the first axial direction. The nozzle includes a first nozzle portion in which a first opening for discharging the liquid is formed and a second nozzle portion in which a second opening that is a coupling port with the first flow path is formed, and a diameter r2 of the second opening in the first axial direction is larger than a diameter r1 of the first opening in the first axial direction.

Abstract: The individual flow path includes a nozzle communicating with an outside, a first flow path, in the middle of which the nozzle is disposed and which extends in a first direction that is an in-plane direction of a nozzle surface of the nozzle plate in which the nozzle opens, a second flow path coupled to the first flow path and extending in a second direction other than the first direction, a third flow path coupled to the second flow path and extending in the third direction other than the second direction, and a pressure chamber which is disposed in the third flow path and in which a pressure change is induced by the energy generating element. A cross-sectional area of the first flow path is smaller than a cross-sectional area of the second flow path.

Abstract: A load cell for use in detecting a load imposed thereon which includes a body (30) in which strain is induced in proportion to the imposed load, and a strain sensor (40) for detecting the strain induced in the body (30). The body (30) is a plate member having a longitudinal axis (X) and the strain sensor (40) is mounted on the body (30). The body (30) has an opening (31) defined therein at a location intermediate of the length of the body (30) so as to define a fixed rigid body forming region (70) at one end thereof, a movable rigid body forming region (71) at the opposite end thereof opposite to the fixed rigid body forming region (70) in the longitudinal direction (X), and side connecting strips (30b, 30b) spaced by the opening (31) from each other in a widthwise direction (Y) of the opening (31) and connecting the fixed rigid body forming region (70) and the movable rigid body forming region (71) together.

Abstract: A load cell for detecting a load imposed thereon and for improving the productivity thereof. The load cell includes a strain inducing device (1) made of metal and including a strain generating area (6) for generating a strain as a function of the load, and a strain sensor (40) including a metal substrate (41) having a strain detecting element (43) formed thereon for detecting the strain generated at the strain generating area (6) of the strain inducing means (1). The strain sensor (40) is mounted on the strain inducing device (1) with the metal substrate (41) welded thereto.
