There is provided a heating device that is capable of increasing heating efficiency of a heating target by microwave irradiation. The heating device includes a microwave irradiator configured to irradiate a heating target with microwaves, and a collector configured to collect fluid generated from the heating target that is irradiated with the microwaves. The microwaves are electromagnetic waves with a frequency of 300 MHz to 30 GHz, for example. The heating target includes metal, for example. Furthermore, the heating target includes non-metal such as oil, organic compound, and water, for example. When the heating target is irradiated with the microwaves, the heating target is heated, and non-metal with lower melting point and boiling point than metal becomes fluid and is separated from the heating target.

Heating device

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.

Control device for shift-by-wire system

A control device of a vehicle including an engine, a power transmission device, a shift operation device, and a switching device includes: a shift-switching control portion outputting the control command signal when it is determined that the shift switching is permitted, and not outputting the control command signal when it is determined that the shift switching is prohibited, at the time of a shift switching operation; and an engine-starting control portion outputting a first signal causing the shift-switching control portion to determine that the shift switching is prohibited and initiating starting of the engine after determining that the shift switching is not being performed when it is determined that the shift switching is permitted at the time of an engine starting operation performed by the driver for starting the engine, and immediately initiating the engine when it is determined that the shift switching is prohibited.

Control device of vehicle

An aerodynamic cover of a suspension device of a vehicle includes an upper horizontal portion that is located on an upper side of the arm member and extends in a horizontal direction, a lower horizontal portion that is located under the arm member and extends in the horizontal direction, an engaging portion that is provided on one of the upper and lower horizontal portions and engaged with the arm member, and a bolt receiving portion that is provided on the other horizontal portion and bolted to the arm member. The engaging portion includes an arm portion extending in the horizontal direction, and a claw portion provided on a distal side of the arm portion and engaged with the arm member. A rib provided on the arm portion extends in a direction of extension of the arm portion, and protrudes in a vertical direction with respect to the arm portion.

Aerodynamic cover of vehicle

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.

Casting apparatus and casting method

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.

Die casting apparatus and die casting method

An exhaust gas cooling device, which cools exhaust gas from an internal combustion engine mounted on a vehicle through heat exchange between the exhaust gas and a coolant, includes: a plurality of tubes through which the exhaust gas flows; a tubular shell which houses the plurality of tubes and is configured to allow the coolant to flow therethrough; and a header plate disposed at an end portion in the shell to prevent the coolant from flowing out of the shell. The header plate includes support holes in which end portions of the plurality of the tubes are fitted and supported, and each of axial end faces of the plurality of tubes is located in the corresponding support hole at a position between both ends of the header plate in a thickness direction of the header plate.

Exhaust gas cooling device

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.

Exhaust gas recirculation valve

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.

Die casting apparatus

The invention provides a die casting apparatus which pumps up molten metal from a molten metal holding furnace through an electromagnetic pump pipe provided with an electromagnetic pump, supplies the pumped-up molten metal to an injection sleeve through the molten metal supply pipe connected with the electromagnetic pump pipe, and a cavity of a die is charged with the molten metal by injecting the molten metal by using an injection tip. An upper end side of the electromagnetic pump pipe and an upper end side of the molten metal supply pipe are connected with each other. The upper end side of the electromagnetic pump pipe is inserted into the upper end side of the molten metal supply pipe, and extends inside the molten metal supply pipe.
