    摘要: A new surface finishing process for stainless steel where beautiful, bright and milky white coloured surface is obtainable even for such grades as high carbon containing 13 chromium steel and high sulfur containing free cutting stainless steel is disclosed. After removing the surface scale, (1) immerse the stainless steel into the 1st treating solution containing nitric acid: 5–40 g/l, hydrofluoric acid: 2–10 g/l and Fe(III) ion: 15–40 g/l for 5–180 sec., then rinse in water, (2) and successesively immerse into the 2nd treating solution containing nitric acid: 120–250 g/l, Fe(III) ion: 15–40 g/l for 30–300 sec., then rinse in water.

    摘要: According to an embodiment, a semiconductor device includes a first circuit block, a first through-substrate via, and a back surface wiring. The first circuit block is provided on a surface side of a semiconductor substrate. The first through-substrate via is provided along a circumference of the first circuit block so as to separate the first circuit block from other circuit blocks. The first circuit block is provided so as to penetrate the surface of the semiconductor substrate. The first circuit block is isolated from the surroundings. The first circuit block has conductivity. The back surface wiring is provided on the back surface side of the semiconductor substrate. The back surface wiring is connected to the first through-substrate via. The back surface wiring connects the first through-substrate via to a power supply terminal or a shield potential terminal.

    摘要: A welding control apparatus according to the present invention includes an integrator for starting calculation of a voltage error integral value Sv2, expressed by a formula (1) given below, from a time when a first pulse period ends and a second pulse period starts in a pulse cycle, based on various data of information regarding a gradient Ks of an external characteristic of a welding power supply and a welding current setting value Is2 and a welding voltage setting value Vs2 both in a second pulse period, which are preset as parameters in the formula (1), as well as on an instantaneous value Io2 of a welding current and an instantaneous value Vo2 of a welding voltage both detected in the second pulse period, a comparator for comparatively determining whether a value of the voltage error integral value Sv2 provided as the calculation result has become 0, and a waveform generator for, per pulse cycle, terminating the relevant pulse cycle and starting a next pulse cycle at a time when the value of the voltage error integral value Sv2 has become 0, whereby a variation in an arc length caused by disturbances is precisely suppressed in pulse arc welding of consumed electrode type: Sv2=∫{Ks(Io2−Is2)+Vs2−Vo2}dt  (1)
