Inventor: OKUNISHI HIROSHI
IPC: C21D1/09
Filed: 1984-11-05
Abstract: PURPOSE:To prevent a shoulder sag of a molten metal, and to form a uniform hardened layer by a simple process by forming the surface of a cam to a flat recessed part shape whose both ends have been heightened, and remelting it by a plasma arc, when bringing the surface of the cam part of a cam shaft to a remelting and hardening treatment. CONSTITUTION:The surface 4 of a cam part 2 of a cam shaft is worked by a grinding stone, and formed to a recessed shape having a flat center part continued to a flat surface 5 of the center, in which a height (h) of both end parts 6, 7 is 0.2-2.0mm, and a width W of inside curved surfaces 6a, 7a is 0.5-5mm. A plasma arc torch 15 is brought to a reciprocating movement in the width direction extending from an end part 6 of this surface to the other end part 7, an arc F remelts, solidifies and hardens the surface, and a surface hardened layer which is excellent in its abrasion resistance and impact resistance is formed. Since both the end parts 6, 7 are projected, a remelted metal does not generate a shoulder sag in both end sides, and a flat remelted and hardened layer 35 can be formed by grinding easily a hardened part 34.

Abstract: PURPOSE:To efficiently reduce and refine molten copper and to obtain high-grade copper materials at a low cost by inserting an oxygen probe which is formed by combining a solid electrolyte into the molten copper in a refining furnace and calculating the oxygen concn. in the molten copper from the electromotive force thereof. CONSTITUTION:The molten copper M desulfurized by oxidation refining is housed in the refining furnace S and is subjected to reduction refining by blowing reducing fluid such as ammonia or heavy oil from the bottom into the furnace, by which the oxygen contained excessively in the molten copper is decreased. The oxygen probe constituted by combining the solid electrolyte is mounted to the front end of a holder 2 and is inserted via a tap hole T into the molten copper M in the above-mentioned reduction method. The solid electrolyte essentially consisting of stabilized zirconia formed by adding CaO to ZrO2 is adequate as the above-mentioned solid electrolyte. This electrolyte is used by combining said electrolyte and a reference electrode consisting of a mixture composed of Fe and FeO. The oxygen concn. in the molten copper M is calculated in a computing part 3 from the electromotive force of this oxygen probe and is displayed. The rate of the above-mentioned reducing fluid to be blown is controlled in accordance with the calculated oxygen concn. The reduction refining of the molten copper M is thereby exactly executed.

Abstract: PURPOSE:To stabilize an oscillation frequency and to attain the easily arrival at a constant temperature condition by supplying a current to a thermoelectric converting element so that a crystal resonator can be maintained to a prescribed temperature based on the signal obtained from a temperature detecting means. CONSTITUTION:The temperature of a crystal resonator 2 detected by a temperature detecting edge 3 is removed by a lead wire 4 as a signal and the signal is supplied to the input side of a comparator 13. The signal is compared with the resistance value of a reference resistor, and when the difference between these two resistance values is absent, a signal (OFF signal) to stop the current supplying from a power source to a thermoelectric converting element is sent from the output side of the comparator 13. On the other hand, when the difference between two resistance values is present, a signal (ON signal) to supply the current from the power source to the thermoelectric converting element is sent from the output side of the comparator 13. The sent ON signal is supplied to an ON-OFF switch 14, and then, the current is supplied from the power source to the thermoelectric converting element. When the signal is an ON signal, a power source changing-over switch 15 reversely rotates the direction of the current supplied to the thermoelectric converting element when the environment temperature of the thermoelectric converting element is higher and lower than the set temperature.
