A fan motor silicon steel sheet structure and a fan motor thereof. The silicon steel sheet structure includes a silicon steel sheet assembly having multiple silicon steel sheets, which overlap one another. The silicon steel sheets include at least one first silicon steel sheet and multiple second silicon steel sheets. The first silicon steel sheet has a first bore and at least one protrusion section. The protrusion section inward protrudes from an inner circumference of the first bore. The first silicon steel sheet is overlaid on one side of the second silicon steel sheets. Each of the second silicon steel sheets has a second bore in communication with the first bore. The fan motor silicon steel sheet structure is able to effectively secure the bearing and provide a dustproof effect. With such structure, the manufacturing cost of the fan motor is lowered.

In a grommet for a vehicle floor cover, receptacles formed in a generally cylindrical inner surface of a female tubular body making up part of one grommet portion receive protrusions formed on a generally cylindrical outer surface of a male tubular body making up part of a second grommet portion. The bottom grommet portion may have chamfered gussets formed adjacent a bottom retention flange in order to accommodate vehicle floor mats or trays of different thicknesses. Stud holes created in respective ones of the grommets receive studs of intentionally different shape or orientation, thereby militating against installation of the floor cover upside down.
摘要:
This disclosure provides an aperture plate coated with a composition comprising a fluorinated compound and an organic compound selected from the group consisting of a urea, an isocyanate and a melamine. This disclosure also provides a process of applying a coating composition to an aperture plate, comprising adding a fluorinated compound, an organic compound selected from the group consisting of a urea, an isocyanate and a melamine, and an optional catalyst together in a solvent to form a coating composition, applying the coating composition to a base film, and curing the base film. This disclosure also describes replacing the aperture plate with polyimide film, where the polyimide film is coated with the above-described coating composition before a laser cutting process.

A cushioning element has a first gelastic cushion element made from a flexible, resilient, gel cushioning media having shape memory. The first gelastic cushion element has a first hub section, and a first spoke and a second spoke. Each spoke has a proximal end that extends from the first hub section. Each distal end and the spoke area between the distal end and the proximal end does not interconnect to the other spoke, and/or a second gelastic cushion element having a second hub section and corresponding spokes. Each distal end is positioned near and/or contacts the second gelastic cushion element. At least one of the first hub section, the first spoke and the second spoke is capable of buckling beneath a protuberance that is located on the object.
摘要:
An epitaxial base is provided. The epitaxial base includes a substrate and a carbon nanotube layer. The substrate has an epitaxial growth surface and defines a plurality of grooves and bulges on the epitaxial growth surface. The carbon nanotube layer covers the epitaxial growth surface, wherein a first part of the carbon nanotube layer attached on top surface of the bulges, and a second part of the carbon nanotube layer attached on bottom surface and side surface of the grooves.
摘要:
An uncured acoustic absorbing member (1, 31) for cavity sealing comprises a thermally inert carrier (8, 38) and a thermally expandable material (6, 40) applied to the carrier. The carrier (8, 38) contains openings (3, 33) which become covered when the thermally expandable material is expanded to seal the cavity. The acoustic absorbing members (1, 31) are particularly useful for sealing automotive cavities to provide acoustical abatement and to prevent the entry of fluids into the cavity.
摘要:
A container (10) having a valve flap (20) which is movable between a closed position, whereat it is seated on the seating area (18) to close an evacuation port (16), and an opened position, whereat it is unseated from the seating area (18) to open the evacuation port (16). A label structure (26) includes a film layer (28) forming a seat platform on which a seating area (18) is located and/or a film layer (30) forming a flap platform on which the valve flap (20) is located. A plurality of label structures (26) can be efficiently and economically mass-produced by a label-manufacturer and then supplied to the container-manufacturer for incorporation into the containers (10).
摘要:
A method of producing a stitched perforated sheet material including providing a sheet material (3) with a perforated region 4 and an unperforated region (5). The sheet material is then stitched in the unperforated region, but adjacent to the perforated region. This gives an overall perforated appearance whilst avoiding the problems associated with stitching through a perforated material.
摘要:
It is an object of the present invention to provide a glass substrate having plural through-holes which is not likely to peel from a silicon wafer, even though laminated on and jointed to a the silicon wafer and then subjected to heat treatment. The above object is accomplished by a glass substrate having an average thermal expansion coefficient of from 10×10−7 to 50×10−7/K within a range of from 50° C. to 300° C., having plural through-holes with a taper angle of from 0.1 to 20° and having a thickness of from 0.01 to 5 mm.
