Abstract: A process of producing optical devices is provided including transferring a first substrate comprising one or more devices to a laser dicing tool, the laser dicing tool including a filamentation stage and a singulation stage. One or more device contours are created on the first substrate in the filamentation stage. The optical devices are singulated from the first substrate along the one or more device contours in the singulation stage. The devices are transferred to storage or for further backend processing.

Abstract: A heater includes an insulating base, a resistance heating element, and a hollow member. The base includes an upper surface and a lower surface. The resistance heating element extends inside the base along the upper surface and the lower surface. The hollow member includes a first plate-shaped part laid over the lower surface, a second plate-shaped part facing the first plate-shaped part through a space, and a side surface part surrounding the space from an outside in a planar direction of the first plate-shaped part and the second plate-shaped part.

Abstract: A method of joining a razor blade to a blade support to form a razor blade assembly, the method including: directing a laser beam having an adjustable power output at an upper surface of the razor blade; and while advancing the laser beam along the razor blade: a) applying the laser beam at a first power output to the razor blade; b) reducing the first power output of the laser beam to a second power output; and c) applying the laser beam at the second power output to the razor to form a weld area joining the razor blade to the blade support. The weld area may be elongated and may include (i) a ratio of depth:width that is greater than about 2:1, and/or (ii) a ratio of length:width that is greater than about 5:1.

Abstract: A control method for gas-shielded arc welding includes providing a normal arc period in which the welding current is maintained at a setting current Icc set in advance, and providing a separation control period after the separation timing of the molten droplet is detected in the normal arc period, the separation control period including a current decreasing section, a current maintaining section, and a current increasing section. In the separation control period, at least one of the following controls for preventing a short circuit is performed: control of an output voltage, control of a feeding speed, and control of a gas ratio.

Abstract: A welding tool for a robot welds together a first component and a second component by using a metallic welding element disposed within a through-hole in the second component. The welding tool includes a welding torch attached to an arm, an element pusher that is attached to a distal end of the arm and disposes the held welding element between the welding torch and the through-hole and disposes at least a part of the welding element within the through-hole, a component pusher attached to the distal end of the arm and movable in an axial direction of a distal end of the welding torch, and a driving device that presses the component pusher against the second component. The element pusher is movable in the axial direction relative to the component pusher.

Abstract: A tea making appliance may include a base, a particulate guide, a tea leaf container, a motorized leaf distributor, a reservoir, a water pump, a heating element, and a controller. The base may define a dispenser cavity. The particulate guide may be directed at the dispenser cavity. The motorized leaf distributor may be provided to selectively provide tea leaves to the particulate guide. The water pump may be in fluid communication with the reservoir upstream from the dispenser cavity to direct water thereto. The controller may be configured to initiate an automated brewing operation that includes receiving one or more data points regarding a physical user condition, selecting a personalized tea style based on the received one or more data points, and dispensing a predetermined tea mass of the personalized tea style automatically in response to selecting the personalized tea style.

Abstract: Provided are a cleaning device and a method for cleaning a vulcanization mold. At the time of cleaning a molding surface of a vulcanization mold by irradiating with a laser beam from a laser head, an inert gas is supplied from a supply nozzle and an irradiation range of the molding surface irradiated with the laser beam is brought into an atmosphere of the inert gas.

Abstract: A laser marker includes: a base including: a first guide portion; and a restriction part; a laser oscillator configured to emit laser light, the laser oscillator being removably mounted to the base by sliding in a mounting direction with being placed on the base, the laser oscillator including: a second guide portion extending in the mounting direction, the second guide portion being configured to be engaged with the first guide portion; a contact part configured to be in contact with the restriction part in a case the laser oscillator is mounted to the base; and an expander; and a scanner having an insertion part, the expander being inserted into the insertion part in a case the laser oscillator is mounted to the scanner, and the scanner being configured to scan the laser light emitted from the laser oscillator.

Abstract: A heating cooking apparatus includes a microwave supply unit, a drawer portion, and a grid body made of metal. The microwave supply unit is configured to supply microwaves to a heating cooking chamber. The drawer portion is drawable with respect to the heating cooking chamber. A heated object is placed on the grid body. The drawer portion includes a moving body made of metal and an engagement portion made of non-metallic material. The moving body is configured to move between an accommodation position inside the heating cooking chamber and a drawn-out position outside the heating cooking chamber. The engagement portion is disposed on the moving body. When the moving body is at the drawn-out position, the grid body is engageable with the engagement portion.

Abstract: A capsule containing a substance for the preparation of a beverage has an aluminum capsule body and a cover sheet hermetically closing off the capsule. The capsule body has a flange with a deformable sealing ring portion with an inner wall portion extending from and contiguous with an inner base portion of the flange, an outer wall portion extending from and contiguous with an outer base portion of the flange and a bridge portion interconnecting the inner wall portion and the outer wall portion. The bridge portion is located axially spaced from the base portions of the flange. In radial cross-sectional view, a top of the bridge portion axially most remote from the base portions of the flange is flat or has a center plane curved with a radius of curvature larger than two times a wall thickness of the top of the bridge portion.
