摘要： A casting apparatus includes: a mold including a first mold segment and a second mold segment; and a transfer device that is configured to transfer a core to the first mold segment and place the core in the first mold segment, and to receive and transfer a casting. The transfer device includes a support part, a robot arm, a core grasping mechanism being provided on the support part, and a casting receiving part being provided on the support part. The transfer device is configured such that the robot arm moves the core grasping mechanism so as to place the core in the first mold segment, and moves the casting receiving part so as to receive the casting by the casting receiving part.

摘要： In an EGR valve, a valve element is moved with respect to a valve seat to adjust a passage section width of a measuring section, thereby regulating an EGR gas flow rate in a passage. The valve seat includes a valve hole, a first end face facing to a downstream side of the passage and a second end face facing to an upstream side of the passage. The inner circumferential surface of the valve hole has a concave curved shape with an inner diameter gradually increasing toward the second end face. The valve element is placed inside the valve hole to be movable in between a fully closed position and a fully open position. While the valve element is placed in the fully open position, passage section widths of parts of the measuring section in an EGR gas flow direction are approximate to each other.

摘要： A control device supplies electric power to a shift-by-wire system to a sub power supply until starting of an engine by automatic start control is completed after the engine has been stopped by automatic stop control. The control device performs a stopped range switching process in response to outputting of a signal for requiring switching of a shift range from a selection device when electric power is supplied from the sub power supply to the shift-by-wire system. In the stopped range switching process, the shift range is switched to a selected shift range when a voltage of the sub power supply is equal to or greater than a threshold value. On the other hand, the shift range is switched to a neutral range when the voltage of the sub power supply is less than the threshold value.

摘要： In a die casting apparatus, during feeding of molten metal by an electromagnetic pump, a molten metal level sensor repeatedly detects a during-feeding level of the molten metal stored in a molten metal holding furnace; a control unit corrects a molten metal feeding voltage to a during-feeding voltage based on the repeatedly detected during-feeding level of the molten metal such that an amount of the molten metal fed by the electromagnetic pump coincides with a prescribed amount; the control unit applies the during-feeding voltage to the electromagnetic pump to cause the electromagnetic pump to feed the molten metal from the molten metal holding furnace into a plunger sleeve; and casting is performed through an injecting operation in which the molten metal fed into the plunger sleeve is extruded by a plunger tip to be injected into a cavity.

摘要： A die casting apparatus includes: an electromagnetic pump body disposed at a plunger sleeve-side end portion of a molten metal holding furnace; and a connecting pipe connected to the electromagnetic pump body and the plunger sleeve to provide communication between the electromagnetic pump body and a molten metal feed port, the connecting pipe being separable from the electromagnetic pump body. The die casting apparatus further includes a moving mechanism configured to allow the electromagnetic pump body to move between an inclined state where the electromagnetic pump body is inclined with respect to a horizontal plane in the molten metal holding furnace at an angle of approximately 45 degrees and an upright state where the electromagnetic pump body is perpendicular to the horizontal plane in the molten metal holding furnace.
