Abstract: An automated cooking device for washing a cooking container includes a controller controlling driving of a container holder to change the container holder to any of an ingredient receiving posture in which the cooking container receives ingredients from a supply device, a cooking posture in which the cooking container is rotated in a state in which the cooking container is inclined forward with respect to a cooking table to stir the ingredients, a serving posture in which the container holder is inclined forward more than in the cooking posture with respect to the cooking table to face downward to a dish on the front side of the container holder, and a washing posture in which a rotation support mechanism of the container holder is inclined backward with respect to a base frame and the cooking container is washed on a rear side of the container holder.

Abstract: An automated food cooking system is capable of cooking a plurality of kinds of foods in accordance with an order from a customer and includes an order reception device that receives the order from the customer, a food base preparation device that prepares a food base according to the order, a seasoning adding device, a topping device, a heat-cooking device, a distribution device, a transportation device that transports the food base, and a control device that is connected to each of the devices. The transportation device can transport the food base to at least a position of the food base preparation device, a position where the seasoning adding device adds a seasoning ingredient, a position where the topping device tops with a cooking ingredient, an input position and an output position of the heat-cooking device, and an input position and an output position of the distribution device.

Abstract: A solder dross removal apparatus includes a holder adapted to be pivotably mounted to a container within which a pool of molten solder is kept at preset temperature. Dross is introduced into the container. A dross cutter assembly includes shafts rotatably supported by the holder and flat elongated cutter elements mounted on the shafts. The cutter elements are disposed perpendicular to the surface of the molten solder and partly submerged in the molten solder when the container is closed by the holder. The cutter elements are angularly offset from each other so that each end of the cutter elements lies on a spiral path. The cutter elements are rotated to repeatedly cut the dross into smaller pieces and force the dross as cut into the molten solder. This process removes oxides from the dross, and any free, reclaimed solder is returned to the molten solder.

Abstract: When a printed board is soldered by a dipping method, a great deal of dross is generated on a jet solder tank. The dross is a mixture of melted solder and oxide. A worker takes out the dross from the jet solder tank, and throws it away. Thus, a large amount of the solder is consumed. The present invention relates to a separating device for separating oxide and solder from dross. A container (21) is provided with a heater (22). A cover (24) is set over the container (21) to be freely attachable or detachable, and further a non-oxidizing gas supplying opening (28) is made in the cover (24) or the container (21). A stirring spatula (25) for stirring the surface of a melted solder (23) put into the container (21) is set near the surface of the melted solder (23).

Abstract: An automatic wave soldering apparatus includes a solder reservoir for holding a supply of molten solder and a solder nozzle vertically disposed in the solder reservoir to establish a solder wave through which a printed circuit board is moved. A pair of trapezoidal elements are secured within the nozzle. A Y-shaped baffle is disposed between the trapezoidal elements to form upwardly inclined narrowed upstream and downstream outlets. The upstream and downstream outlets are inclined at an acute angle against and in the direction of movement of the printed circuit board, respectively. A pair of valves are disposed at opposite sides of the baffle to selectively open and close the outlets. The bottom side of each of the trapezoidal elements forms a step to promote turbulence in the solder wave. The trapezoidal elements and the baffle collectively serve to increase the flow velocity of the molten solder through the outlets.

Abstract: A printed circuit board which has been soldered in a molten solder bath is cooled immediately thereafter with a cooling liquid at a rate of at least 10° C./second. Thermal effects of high-temperature solder during soldering are suppressed, and the metal matrix of the solder is refined, resulting in soldered connection of increased strength.
