    摘要: Exemplary embodiments provide a resistance welding method capable of stabilizing quality or improving efficiency of resistance welding such as spot welding. This resistance welding method comprises a calculating step of calculating resistance ratio X of a second electric resistance value R2 of workpieces to be joined in residual heat after Joule heating stops to a first electric resistance value R1 of the workpieces immediately before the Joule heating stops or vice versa (R2/R1 or R1/R2); a determining step of determining whether the resistance ratio X is equal to or greater than a threshold value Xn, and a reheating step of carrying out the Joule heating again when the resistance ratio X is smaller than the threshold value Xn. Thereby at least part of a welding portion is melted and solidified to reliably form a nugget, and a stably resistance-welded member can be provided.

    摘要: In a resistance welding method, by controlling the power amount from a melting start time onward, the weld quality may be stabilized efficiently, even when a disturbance is present, because of the correlation between the amount of power input from the melting start start time and a resulting nugget. The resistance welding method includes: pressing an electrode against a workpiece; inputting power to the workpiece through the electrode to subject the workpiece to Joule heating; detecting the melting start time, which is the time at which at least a portion of the faying portion of a workpiece starts to melt when subjected to Joule heating; calculating a first power amount input into the workpiece from the melting start time; and determining whether the first power amount has reached a first set value; and continuing the Joule heating until the first power amount reaches the first set value.

    摘要: A key switch is provided which includes a key top which is pressed down by optional force and which can move in the press-down direction. The key switch also includes a spring for generating a rebound according to the optional force applied to the key top. The key switch also includes a housing having an elastic member which generates the press-down force against the rebound according to a distance by which the key top moves. The key switch realizes the press-down characteristics in which the inclination of the rebound is zero or negative.

    摘要: A key switch comprising a base, a key top arranged above the base, a pair of link members interlocked to each other and operatively engaged with the base and the key top to support the key top above the base and direct the key top in a vertical direction, and a switching mechanism for selectively opening and closing an electric circuit in connection with a vertical movement of the key top. Each of the link members includes a sliding portion slidably and shiftably engaged with either one of the base and the key top. At least one plate spring is disposed between at least one of the link members and either one of the base and the key top with which the sliding portion is engaged, to exert a biasing force, relative to a shifting amount of the sliding portion, onto at least one of the link members in a direction different from the vertical direction. The plate spring includes, in an integral manner, a first spring portion extending along a fixed-end side in a direction substantially parallel to a shifting direction of the sliding portion of each link member and a second spring portion extending along a free-end side in a direction intersecting the first spring portion.

    摘要: A keyboard including a housing unit for slidably supporting a key top; and a support panel unit carrying a switch to be operated by the key top. The housing unit can move between a first position apart from the support panel unit and a second position close to the the support panel unit, and the first position is such that the key top vertically shifting from but confronting the switch, when pressed, can operate the switch, and the second position is such that the key top being horizontally deviated from the switch, even if pressed, cannot operate the switch. The housing panel may support the elastic member for supporting the key top upon a main surface thereof, a first horizontal end of the elastic member may be fixed to the housing panel, and a second horizontal end opposite the first end of the elastic member may be movable in the horizontal direction. A switch is vertically pushed by the key top; and a support panel may hold the switch thereon, and may support the second horizontal end of the elastic member. The support panel may slide horizontally to push the second horizontal end so that the elastic member may be elastically deformed for respective center lines of the key top and the switch to substantially align each other.

    摘要: A joined body has a joint, which includes a first plate-shaped workpiece made of a first metal, and a second plate-shaped workpiece made of a second metal. The first plate-shaped workpiece, and the second plate-shaped workpiece are overlapped each other partially at least. The joint is made by means of friction stir joining by superimposing a rod-shaped body made of a third metal onto the overlapped first plate-shaped workpiece and second plate-shaped workpiece and then rotating it while pressing it onto the first plate-shaped workpiece. The joint further includes a coalesced section made of the first metal that coalesces on a surface of the second plate-shaped workpiece, a built-up section made of the third metal, and a composite section made of a mixture of the first metal and the third metal that integrates the coalesced section with the built-up section.
