Abstract: A vertical cavity surface emitting laser (VCSEL) includes a semiconductor device having a pair of mirror portions, an active region, a tunnel junction, a pair of cladding layers and a substrate. Heat generated by the VCSEL dissipates through the cladding layers, which utilize an indium phosphide material. The VCSEL also includes selective etches that are used to aperture the active region to allow electric current to be injected into the active region.

Abstract: A lathe (10) includes a support structure (12) which supports a magazine (14) in a substantially vertical operative orientation. The magazine (14) is rotatably supported in a carriage (24). The magazine (14) is a multi-spindle magazine and supports a plurality of workpieces. A workstation head (40) is mounted on the housing (18). The workstation head defines a plurality of workstations (46). Each workstation head includes a plurality of working tools.
Abstract: An airtight pouch or packaging (10,20) made of synthetic material for the preservation of food products (12) is obtained by sealing (13, 14, 15) and cutting said synthetic material by an automatic packaging machine with a horizontal or vertical motioning of the product. The packaging (10,20) is constituted by a single peelable type film (11) consisting of an oriented polyamide layer coupled with a coextruded peelable polyethylene layer, the film being folded once on the polyethylene layer side in order to form the inner part of the packaging.

Abstract: A pair of toys or novelty devices for moving relative to the surrounding environment comprises a body for each toy. The body of at least one of the toys or devices to be capable of movement over a surface. A switch with the body activates a magnet to react from one state to another state, and in the second state causing at least one of the devices or toys to move relatively closer together in the surrounding environment. A microprocessor circuit with the body is connected with the magnet such that the switch causes the magnet to operate from one state to another state. When there are a pair of toys, which appear as pets, which get together, and when they appear to kiss each other, there is emitted a kissing sound. Then the cheeks of the pets glow and become red color, resembling the human emotion and reaction.
Abstract: This invention relates to an improved method of manufacturing an anode assembly of a magnetron used in a microwave oven to generate an electromagnetic wave for cooking foodstuffs therein. The method comprises coating of entire surfaces of vanes with a brazing material to join an anode cylinder, upper and lower strip rings and an antenna lead contacting the vanes by the coated brazing material on the vanes, whereby enhanced efficiency of a production process, mass production and reduction in costs may be achieved.
