Abstract: An optical processing head capable of downsizing an apparatus while increasing the shaping accuracy of optical processing is disclosed. The optical processing head performs processing while moving, in a predetermined moving direction on a processing surface, an optical spot formed by condensing light emitted by a light source. The optical processing head includes an optical element that condenses light emitted by the light source to generate the optical spot of a shape elongated in the moving direction of the optical spot. Part of the optical spot is set as a processing region, the front side and/or rear side of the processing region in the moving direction is set as a pre-heating region and/or post-heating region, and a processing target object before and/or after processing in the region is heated.

Abstract: Provided is a laser welding apparatus for spacer grid of nuclear fuel assembly comprising a base frame in which a chamber installment hole is formed horizontally to the center in a way that the hole penetrates the chamber and a guide rail is installed along the chamber installment hole; a welding chamber unit assembled with the base frame in guidance by the guide rail and equipped with an operable door in front and a glass window at the top to be airtight; a laser welding unit mounted on the base frame for radiating laser through the glass window to weld spacer grid in the welding chamber; and a locking member for fixing the welding chamber on the base frame.

Abstract: A system for use with a block heater connected to an engine for pre-start heating of the engine. The system includes a power source, a relay assembly coupled to the power source, a temperature sensor, and a controller. The relay assembly, when closed, electrically connects the power source to the block heater, to thereby energize the block heater to heat the engine. The temperature sensor senses an ambient temperature indicative of a temperature of the engine. The controller is programmed to selectively activate the relay assembly to energize the block heater such that the engine coupled to the block heater is heated from the sensed ambient temperature to a target temperature at approximately a target time.

Abstract: A product conveying and coating system includes at least first and second, sequentially arranged conveyor belts, with at least the second conveyor belt being a solid belt. Interposed in a gap between the first and second belts is a dispenser head of a coating manifold. The dispenser head spans the gap between upper surface portions of the first and second conveyor belts, with an elongated side wall outlet portion of the dispenser head being exposed, in a downstream direction of the overall conveyor unit, to the upper surface of the second conveyor belt. The system provides for dispensing of coating material directly onto the second, solid conveyor belt and enrobing at least bottom and partial side portions of food products upon the solid belt. Provisions are made for scraping from the solid belt, removing from the coated food products and recycling excess coating material.

Abstract: Provided are a layered heat exchanger that can prevent deterioration of sealing property due to deformation of sealing portions of inlet and outlet header sections when a PTC heater is sandwiched between flat heat exchanger tubes, and is pressed to be brought into close contact with the flat heat exchanger tubes, and a heat medium heating apparatus and a vehicle air-conditioning apparatus using the layered heat exchanger.

Abstract: Microwave irradiator 12 is attached to a furnace main body of a heating furnace 11 having microwave permeability. A running passage for passing a fiber member F which is the object to be heated is formed inside the heating furnace 11. A first tubular member 13 made of a first microwave heat-generating material absorbing microwave energy and generating heat is rotatably disposed around the running passage. A second tubular member made of a second microwave heat-generating material absorbing microwave energy and generating heat is disposed in the first tubular member 13. The fiber member F is heated and calcined while running the fiber member F containing carbon in the running passage of the second tubular member 14.

Abstract: An energy transportation and grid support system utilizes at least one transportable containment module capable of storing thermal or chemical energy typically produced from renewable or geothermal sources and providing connectivity with energy conversion equipment typically located in a land or sea-based operating facility. The system includes circuitry to hookup to an adjacent electricity grid for the provision of grid support and/or piping to move thermal energy typically used to drive steam turbines generating ? electricity. The operating facility also includes a communication arrangement to link with and exchange operations control data with a grid or heating operator and the energy transportation operator. The invention is directed to both apparatus and method for the energy transportation and grid support system.

Abstract: A device for separating a first space and a second space from one another is disclosed. The device comprises a partition wall, arranged such that the first space and the second space are located on opposite sides of said partition wall. The partition wall is provided with a through aperture, which connects the first space and the second space and allows a bulk material to move from the first space into the second space. A shutter is provided, slidingly movable with respect to the partition wall, for selectively opening and closing the through aperture. The shutter has a port, which can be selectively brought in an alignment position and in an out-of-alignment position with respect to the through aperture.

Abstract: A welding gun assembly having a connection between a diffuser and the inner gun tube which provides increased strength between the diffuser and the gun tube to prevent inadvertent damage to the welding torch and upstream components. The diffuser comprises an engagement portion which engages with, and overlaps, at least a part of a sturdier portion of the inner gun tube. This engagement provides a stronger and more stable connection between the gun tube and the diffuser.
