摘要： Provided are a conveying jig, a method of manufacturing the conveying jig, and a method of heat-treating metal rings using the conveying jig. The conveying jig is provided with a base and ten holding shafts raised from the base. Ridges and grooves are alternatively provided in the side wall of each holding shaft. The metal rings are held in position by being engaged in the grooves in the holding shafts. The space enclosed within the holding shafts is communicated with the atmosphere, and this allows, when the metal rings held by the conveying jig are subjected to heat treatment in a heat treatment furnace, an atmospheric gas to circulate in the space enclosed within the holding shafts.

摘要： A metal ring made of maraging steel is heated in the presence of a halogen compound gas, so as to eliminate an oxide film from the surface of the metal ring and to form a halogenous compound film. Thereafter, the metal ring is heated under a vacuum or reduced pressure atmosphere to eliminate the halogenous compound film, and then it is maintained under an atmosphere comprising ammonia at a processing temperature ranging between 450° C. and 500° C. for a processing time ranging between 30 and 120 minutes, so as to carry out a nitriding processing. The above nitriding processing comprises the steps of: placing the above metal ring into a heating furnace and raising the temperature inside the heating furnace to the above processing temperature; introducing a first mixed gas consisting of 50% to 90% ammonia byvolume, 0.1% to 0.9% oxygen by volume, and a residual volume consisting of nitrogen into the heating furnace, and maintaining the above processing temperature, so as to form a nitrided layer on the surface of the metal ring; and when the one-third to one-half of the processing time has passed, replacing the atmosphere inside the heating furnace by a second mixed gas consisting of 0% to 25% ammonia by volume and a residual volume consisting of nitrogen, and maintaining the above processing temperature until the remaining processing time passes.

摘要： A nitriding process for a maraging steel is provided in order to increase the compressive residual stress of the maraging steel. A workpiece is made of maraging steel in which titanium is solid solved, and a partial amount of the titanium is oxidized at the surface of the workpiece so that titanium oxide is positively generated and concentrated at the surface. Then a reducing treatment is sufficiently performed as a pretreatment of a nitriding step, thereby removing oxygen. As a result, surface concentration of the titanium in an activated state is increased. Next, by performing the nitriding treatment, the reduced titanium and the solid solved titanium combine with nitrogen as titanium nitride. The titanium is in the activated state and is thereby easily nitrided. Moreover, the surface concentration of the titanium in the activated state is high, whereby a large amount of nitrogen infiltrates into the workpiece.

摘要： The present invention provides an aligning apparatus which is capable of aligning auxiliary connecting plates such as a testing fixture plate so as to fit to both sides of a substrate. A camera 13a monitors aligning marks provided on a substrate 6 and a first auxiliary connecting plate (i.e. a lower surface testing fixture plate) 8 to carry out an aligning operation by moving the substrate 6 by means of an XY.THETA. table 5. A first plate-fitting member (a vacuum suction member) 32 fixes the substrate 6 and the first auxiliary connecting plate 8. On the other hand, a camera 13b monitors aligning marks provided on the substrate 6 and a second auxiliary connecting plate (i.e. an upper surface testing fixture plate) 11 to carry out an aligning operation by moving the second auxiliary connecting plate 11 by means of the XY.THETA. table 5. A second plate-fitting member (a vacuum suction member) 33 fixes the substrate 6 and the second auxiliary connecting plate 11. Thus, the auxiliary connecting plates can be accurately aligned on both sides of the substrate through one table.
