An ink jet head is provided which includes an electrothermal converting body having a heat generating resistor which generates, upon energization, heat energy to be directly applied to ink on a heat acting face to discharge the ink. The ink jet head is characterized in that the heat generating resistor is formed from a non-single crystalline substance substantially composed of Ir and Ta and containing the Ir and Ta at the following respective composition rates:35 atom percent .ltoreq.Ir.ltoreq.77 atom percent, and23 atom percent .ltoreq.Ta.ltoreq.65 atom percent.

A split ring spring for snap fasteners has a burr extending from each end of the ring spring in a direction parallel to the imaginary central axis of the ring spring. When a stud member is snapped with a socket member in which the split ring spring is incorporated, the burrs do not damage or scar a body of the stud member. The ring spring having such unobjectionable burrs is produced by feeding a length of a strip of resilient material transversely across a mandrel, then severing the length off the strip in a direction parallel to the longitudinal axis of the mandrel while holding the length on the mandrel, and thereafter bending the severed length of strip around the mandrel.

A female snap button detachably receives a projection of a male snap button in a projection-receiving space. The female snap button includes an annular protrusion rising from a base and defining the projection-receiving space. In the annular protrusion, there are formed thick-walled portions with the thickness from the inner surface of the protrusion to the radially outer side being relatively thick and thin-walled portions with the thickness being thinner than that in the thick-walled portions. The thick-walled portions and the thin-walled portions are arranged alternately in the circumferential direction.

According to one embodiment, a flexible printed wiring board includes a component mounting portion to which a component is mounted and to which a reinforcing sheet is bonded. The component mounting portion includes an inner layer comprising a wiring pattern, and an outermost film layer disposed to cover the wiring pattern. The outermost film layer, to which the reinforcing sheet is bonded, is formed with a groove such that, when the reinforcing sheet is bonded, the groove extends in a region between the outermost film layer and the reinforcing sheet and communicates with an outside of the region.

A button fixing member made of synthetic resin, used to fix a button having a fixing opening to a cloth, the button fixing member including a plate-like base and a post protruding from the base to a front surface side of the base The post is deformed after it passes through the cloth and the fixing opening of the button when the button is fixed to the cloth. The post includes a cavity extending from an opening on a rear surface of the base to a closed end on the tip side of the post concentrically with the post, and a solid portion between the closed end of the cavity and the tip of the post. The axial length of the solid portion is set to be ⅕ or more of the length of the part of the post from the front surface of the base to the tip of the post.
