Abstract: To provide a single crystal production apparatus capable of efficiently producing a single crystal of relatively high quality, by cooling a melting zone, the device including: a heating part that forms the melting zone from a raw material by irradiation of light; and a supporting part that supports the melting zone in a non-contact manner.

Abstract: A skin effect heating system for long pipelines includes a heater cable disposed in a ferromagnetic or other conductive heat tube, the heater cable and heat tube cooperating to produce heat that is applied to the carrier pipe. The heater cable includes a conductor surrounded by an insulating layer, and then a semiconductive outer layer or “jacket.” The semiconductive jacket contacts the inner surface of the heat tube, where the charge density of the return current carried by the heat tube is at its highest. The semiconductive jacket material has a resistivity that is sufficiently low to reduce or eliminate arcing events such as corona discharge by allowing accumulated charge on the heat tube to dissipate. The resistivity is also high enough to prevent the return current from flowing into or through the semiconductive outer layer, so that heat production capacity of the system is maximized.

Abstract: A machine (1) for dispensing a beverage (84) from a capsule (2) has: an external housing (10, 30, 30?, 40, 50, 60) having an external front face (10), two external spaced-apart lateral side faces (30,30?) that extend rearwards behind the external front face (10) and that face each other; a beverage outlet (11) located on the external front face (10) and above a front area (20) for placing a user-receptacle (3,4) for collecting beverage (84) from the outlet (11); and a capsule handling device (70) that has a first part (71) and a second part (72) that are relatively movable between a capsule transfer position and a capsule extraction position. At least one part (72) of the first and second parts (71,72) is arranged to translate towards and away from at least one of the two external lateral side faces (30,30?) so that the first and second parts (71,72) relatively move between the transfer and the extraction positions.

Abstract: Provided is a novel method for improving fatigue strength, which is applicable to any small portion that is covered with another member. A method for improving fatigue strength according to the present invention includes: disposing an aid (3, 15) to be opposed to an processing object (2A, 2B, 6) on which a fatigue strength improving process is performed, the aid being configured to assist the improving process; and generating sparks between the aid (3, 15) and the processing object (2A, 2B, 6).

Abstract: Example systems may include an energy source, a material delivery device, and a computing device. The computing device, based on a target height of a layer deposited on a component by directed energy deposition, may control an energy source directed at a component and may control a material delivery device. Controlling the energy source may include advancing an energy beam along a first path to form an advancing molten pool on the component. Controlling the material delivery device may include delivering a material to the advancing molten pool. The material may combine with the advancing molten pool to form a first raised track having an actual height. The layer may include the first raised track. A deposited region of the component may include the layer. The actual height may affect a resultant microstructure within the deposited region.

At least one crest portion of a first heating element is fastened to a corresponding trough portion of a second heating element. The heating elements are arranged in a honeycomb configuration.

Abstract: An additive manufacturing head includes: a nozzle configured to discharge material powder; a rotary member connected with the nozzle, including a first material powder passage formed in the rotary member to direct the material powder to the nozzle, and configured to rotate to cause the nozzle to move in the circumferential direction about a laser beam emitted toward the workpiece; and a stationary member including a second material powder passage which is formed in the stationary member and into which the material powder is introduced, the stationary member being disposed directly beside the rotary member in the direction of the rotational axis of the rotary member. A third material powder passage communicating with the first material powder passage and the second material powder passage and extending annularly about the rotational axis of the rotary member is formed between the stationary member and the rotary member.

Abstract: A brewing apparatus is adapted for brewing articles contained in a capsule, and includes a capsule seat, a control device, and at least one drive mechanism. The capsule seat is adapted to receive the capsule therein. The control device has a slide slot. The at least one drive mechanism engages slidably the slide slot and is connected to the capsule seat. The control device is pivotable to drive slide movement of the at least one drive mechanism, thereby moving the capsule seat and converting the brewing apparatus between a brewing state and a standby state.

Abstract: There is provided an arc welding control method of alternating a feeding rate of a welding wire between a forward feeding period and a reverse feeding period, controlling a welding voltage based on a voltage setting value and alternating short-circuiting periods and arc periods to perform welding. In the arc welding control method a cycle of the feeding rate is changed based on the voltage setting value.
