Vertical slots are provided in the side walls. A partition can be oriented vertically or horizontally within the box. Tabs extending from the partition are slidably positioned within the slots to prevent the partition from sliding about.

A lightweight, insulated chest and method are provided for transportation and storage of perishable and other items which require a temperature-controlled environment. The chest includes insulated side walls, bottom and a hinged cover which is pneumatically sealed to prevent tampering and for thermal security. The chest includes a fluid conduit within the cover for air evacuation and depressurization of the interior and also includes a conduit to provide a vacuum between the walls of the sides and bottom which contain a rigid polymeric foam insulation.

The wall building system and method uses a block for building walls and other structures. The block is formed with an external face member and an internal face member connected by an inner core, which has an outer surface formed with a concave profile. The block is fabricated in one piece to enhance strength and stability. Each face is provided with a continuous groove therearound. The continuous grooves are adapted to receive locking elements therein to interlock the blocks. Utilizing a locking element eliminates the need for binding compounds, such as mortar, thereby greatly reducing labor and material costs.

A MIS type semiconductor device and a method for fabricating the same characterized in that impurity regions are selectively formed on a semiconductor substrate or semiconductor thin film and are activated by radiating laser beams or a strong light equivalent thereto from above so that the laser beams or the equivalent strong light are radiated onto the impurity regions and on an boundary between the impurity region and an active region adjoining the impurity region.

Composite flexible air ducting comprising an elongated inner lining of plastic reinforced by a spirally wound coil member providing an elongated continuous air passage; a layer of natural fiber insulation surrounding the inner lining and an outer sheath surrounding the layer of natural fiber insulation. The outer sheath and the layer of fiber insulation are bonded to each other by a layer of adhesive having substantial thermal insulating properties.

Three-dimensional portions are made of the same PET resin as are flat portions, only thicker. That is, the three-dimensional portions are more rigid than the flat portions. The three-dimensional portions are bonded to the flat portions at cutout portions thereof by a thermo-compression sheet or adhesive tape or the like. Connecting portions are made of PET resin that is thinner than the PET resin of which the flat portions are made. A phase insulation paper is provided in which the connecting portions are bonded at both ends to the flat portions, and an electric motor is provided in which the phase insulation paper is inserted between stator coils.

A transparent glass appliance door is provided with a reflective coating in the shape of a frame, resembling the conventional metal frame which usually surrounds and supports the glass. The reflective frame leaves a clear area through which the interior of the appliance can be viewed.

A refrigerator and a manufacturing method thereof including processes of separately manufacturing partitions dividing a storage space into a plurality of storage chambers from a main body including an inner casing and an outer casing, coupling the partitions to an inner surface of the inner casing, filling a space between the inner casing and the partitions with an insulator, and filling the partitions with the insulator by filling a space between the inner casing and the outer casing with the insulator. Since the insulator uniformly fills the partitions dividing the storage space into the plurality of storage chambers, the partitions may possess improved insulating qualities.

A baseboard structure having air gap insulation, an integrated quarter-round molding segment, and an upper caulk channel for providing a unitary baseboard element for rapid and improved installation. The baseboard comprises an outer, decorative surface having an integrated quarter round element, a lower surface adapted to lie flush on a floor surface, a backside surface and an upper caulk channel. A section of compressible insulation material is located at the junction of the backside and lower surfaces, and is adapted to be pressed into any gaps between the flooring and the wall to seal any air gaps or gaps in thermal resistance. The device incorporates a caulking channel at the junction of the backside and outer surfaces such that the installer may create a seamless transition between the top of the baseboard and the wall with a quantity of caulk while the baseboard lower surface lies flush with floor.

A thermal insulating fluid contains microspheres of hollow spherical particulates. The presence of the hollow spherical particles improves the thermal insulating properties of the fluid by imparting to the thermal insulating fluid a low heat transfer coefficient. The hollow particulates may be inorganic or organic in nature and include hollow spheres of glass, ceramics and plastics. The thermal insulating fluid is capable of controlling the heat transfer from a production tubing or transfer pipe to one or more surrounding annuli and the environment. In addition to reducing heat transfer in the producing well, heat transfer in the fluid produced from the well is also minimized.

A twist-on wire connector having a finger friendly unbiased cushioned cover that covers not only the normal hand gripping region but at least part or all of the normal non-hand gripping region of the twist-on wire connector so that regardless of the way the twist-on wire connector is grasped the user fingers engage the cushioned cover to inhibit finger and hand injury and fatigue from repeated securement of twist-on wire connectors to electrical leads and a method of making a twist-on wire connector with a cushioned cover by placing a soft to the touch material on the exterior surface of the twist-on wire connector.

The invention belongs to the enameled wire processing technical field and relates to an automatic varnishing method for the wire rods of enameled wires. According to the step 1 of the method of the invention, a wire rod is inspected, so it can be ensured that the wire rod is free of quality defects such as wire fracture, bump-cased damage and scratches; and strengthening quality management is enhanced to reduce the influence of other factors on varnishing quality. According to the step 2 of the method, the wire rod passes through an ash removal module, a varnishing module, a layer-uniformizingmodule and a drying device sequentially. According to the step 3, the rotation speed of the ash removal module ranges from 50 to 100 rpm, and it is advisable that the surface of the wire rod should be cleaned until the surface of the wire rod is smooth and is free of dust and oil spots; the parameters of the varnishing module are set so as to automatically match the diameter of the wire rod, andit is advisable that the number of turns of the rotation of a varnishing ring around the wire rod to varnish the wire rod should be 60 to 80 turns per minute; and the layer-uniformizing module is adjusted, so that coating thickness error can meet the requirements of customers. According to the step 4, after the wire rod is inspected as a qualified product, batch production is carried out. According to the automatic varnishing method for the wire rods of the enameled wires of the invention, the above varnishing devices are adopted, the surface coating of the wire rod is uniformized, and therefore, the uniformity of the coating can be improved, and the insulation quality of the wire rod can be improved.
