摘要： The invention provides a process for forging a titanium-based material comprises the steps of: preparing a titanium-based sintered workpiece including at least one of ceramics particles and pores in a total amount of 1% or more by volume, the ceramics particles being thermodynamically stable in a titanium alloy; and heating the workpiece to a forging temperature and forging the same. In the production process, the pores or the ceramics particles inhibit the grain growth during forging. Accordingly, it is possible to carry out the forging at a relatively high temperature at which the titanium-based material exhibits a small resistance to deformation. Moreover, the titanium-based material can maintain an appropriate microstructure even after the forging. Consequently, the impact value and the fatigue strength are inhibited from decreasing.

摘要： A method for manufacturing a cup-shaped article includes making the thickness of a cylinder portion of a cup-shaped configuration uniform, between a step of drawing a flat plate material portion into a cup-shaped configuration and a step of ironing the cup-shaped configuration into a final cup-shaped article. Increasing the thickness may be performed by coining or axial compression. The thickness increasing step may be replaced by a step, provided prior to the drawing step, of providing a plate material portion having a greater thickness at a radially inner portion than at a radially outer portion.

摘要： A cooking oven is provided with a weight detection unit for detecting the weight of a cooking object placed on a turntable. The turntable is movable into and out of a heating chamber associated with the cooking oven by means of a moving unit drivingly connected to the turntable through a lever and connecting rod. A heater and a rotary drive unit for rotating a table upon which the turntable is mounted are controlled according to a signal from the weight detection unit. The cooking oven is also provided with an external input unit for supplying data on the heating operation and on the driving of the turntable. Either manual or automatic operation of moving the turntable back and forth can be selected according to a signal from the external input unit. The cooking oven is further provided with a detection unit for detecting the opening and shutting of its door and a control unit which functions to control the movement of the turntable into and out of the heating chamber commensurate with the opening and the shutting of the door in accordance with a signal from the detection unit for detecting the opening and shutting of the door.
