Title: Method for dropping and raising temperature of gas carburizing furnace and for regulating internal atmosphere of said furnace
Inventor: TABATA SHIGEO
IPC: C23C8/22
Filed: 1982-12-27
Abstract: PURPOSE:To reduce the time required to operate a furnace again by keeping the inside of the furnace in an inert gaseous atmosphere until a carburizing gas is introduced after the beginning of a temp. drop when the operation of the furnace is suspended and started again. CONSTITUTION:When the temp. of a gas carburizing furnace is dropped to suspend the operation of the furnace, an inert gas is introduced into the furnace after the beginning of the temp. drop to remove the carburizing gas and to fill the inside of the furnace with an inert gaseous atmosphere. During the suspension of the furnace, the inside of the furnace is kept in the inert gaseous atmosphere. When the temp. of the furnace is raised to start the operation again, the temp. is raised in the inert gaseous atmosphere after ignition until a carburizing gas is introduced. The carburizing gas is then introduced by a larger volume than the volume during operation to regulate the internal atmosphere of the furnace. Thus, the time required to operate the furnace again is reduced.

Title: Method for casting in metal material or plastic-made member by different kind of material
Inventor: MACHI HIROSHI
IPC: B22D19/00
Filed: 1987-09-12
Abstract: PURPOSE:To prevent the development of crack and casting blow hole by forming a slit, which reaches from inner periphery to outer periphery of an annular member, to the annular member at the time of making cast-in outer shell of the titled annular member by casting or forming method. CONSTITUTION:For example, in ferrous material-made yoke core 1, the slit 3 is formed substantially to radius direction. The Al alloy 2 is cast in the outer periphery of this yoke 1 to form Al alloy case 2. By this method, when the Al alloy 2 at the outer periphery solidifies and shrinks, the width (h) of the slit 3 becomes narrow and the diameter of the core 1 is decreased and also the thickness of the Al alloy case 2 is increased by the shrinkage quantity. In this result, by difference of the shrinkages and cooling velocities between the ferrous material in inner part and Al series material at the outer periphery, the crack developing in the Al alloy case 2 can be prevented.
