Abstract: A welding jig device includes a jig on one side, a jig on the other side, and a jig clamp. The jig on one side includes a joint face on one side that contacts one face of faces exposed on outer surface sides of a plurality of workpieces that are overlaid one on top of the other. The jig on the other side includes a joint face on the other side that contacts the other face of the faces exposed on the outer surface sides of the plurality of workpieces. An opening corresponding to a desired welded portion of the plurality of workpieces is provided in at least one of the jig on one side or the jig on the other side. The jig clamp sandwiches the jig on one side and the jig on the other side together with the plurality of workpieces in a stacking direction of the plurality of workpieces.

Abstract: A device is used for forming a part by welding a plurality of members together, and includes a jig on one side having a joint face on one side, which is adapted to contact one of faces exposed on the outer surface sides of the plurality of members overlaid one on top of the other, and an opening on one side corresponding to a portion of desired welded portions of the part; a jig on another side having a joint face on the other side, which is adapted to contact another face of the faces exposed on the outer surface sides of the plurality of members, and an opening on the other side corresponding to another portion of the desired welded portions of the part and not corresponding to the opening on one side; a laser welding machine on one side that is configured to emit a laser beam toward the opening on one side; and a laser welding machine on the other side that is configured to emit a laser beam toward the opening on the other side.

Abstract: To improve the reliability of controlling overwriting of a nonvolatile memory in a data processing semiconductor device. In a data processing semiconductor device, a control unit which controls reading, writing, or erasing of data in a rewritable nonvolatile memory area has an operation mode that, referring to the input temperature data, controls a temperature range in which writing or erasing of data is performed to be narrower than the temperature range that allows reading of data in the memory area.

Abstract: A power-supply sequence-free electronic circuit is realized without the increase of the number of power supply detectors for detecting the rising of the power supply. The electronic circuit operated by supplying three or more types of power supply voltages to the ground voltage of the circuit generates a first detection signal indicating whether any one of other power supply voltages does not rise by a first detection circuit which is operated with a predetermined power supply voltage as an operation power supply. The electronic circuit generates a second detection signal indicating whether the predetermined power supply voltage rises by a second detection circuit which is provided for each of the other power supply voltages and operated with one power supply voltage of the other power supply voltages as an operation power supply.
