An open elongate profile has side walls (12, 13; 22; 32) oriented relative to each other in a direction of a longitudinal extension (L) of the side walls, with at least one of the side walls (12; 22; 32) having at least one thickness-reduced region (14; 24; 34) along its longitudinal extent (L) and a shaped profile (15; 25; 35) provided in the at least one thickness-reduced region (14; 24; 34) of the at least one of the side walls (12; 22; 32).

A method of fabricating a flash memory devices disclosed wherein, upon formation of sidewall oxide films, a regrown thickness of a screen oxide film is controlled. The width of an element isolation film is reduced by means of an etch process for removing the re-growth oxide film. This allows a floating gate space to be easily secured, and a thickness of the sidewall oxide films is reduced by means of a liner nitride film pre-treatment cleaning process. It is thus possible to secure the trench space, which facilitates gap-filling.

Batch casting of rim sprockets for chain saws as particularly applied to larger rim sprockets experience undesired high scrap rate resulting from porosity and chip-out. The solution is to ensure flow of molten steel throughout solidification of the molten steel in the sprocket mold while retaining molten steel portals or gates of a size that permits breakaway of portal stems. Such enhances the cooling rate of the molten steel in the sprocket mold which was found beneficial. The objective of reduced scrap rate is thus accomplished by maintaining a ratio of mass to surface area of the sprockets being cast to no greater than about 4 grams of material to each square inch of surface area and alternatively provide through bores through the rim sprockets which additionally assist in wood chip removal. This design also reduces the material content which reduces the cost and weight of the product.

An energy absorber for improving passenger safety in a vehicle during an impact to the vehicle, the energy absorber comprising a hollow body having a base defining a proximal end of the body, the base being configured to affix the body to a portion of the vehicle, the body further including a sidewall extending from the base and terminating in a distal end of the body, the sidewall having an interior surface and an exterior surface, the interior surface including a portion defining an interior step transition, the exterior surface including a portion defining an exterior step transition, the interior and exterior step transitions being provided at locations axially offset from each other along the sidewall.

A contact module for a circuit breaker is disclosed, comprising: a base, a cover, an operation mechanism, at least three kinds of asymmetrical single-pole switches and a release mechanism. The cover is mounted on the base to form a space, where the mechanisms and the switches are disposed. The operation mechanism is connected to one switch; the release mechanism to the at least three switches. Each switch comprises a strong side and a weak side. For each switch, there is a thick contact housing on the strong side connected to a thick shaft, and a thin one on the weak side connected to a thin shaft. A rotor component has a single contact spring mounted on the weak side. Rotation shafts are connected by a linkage shaft to connect the single-pole switches; a strong side of one switch is connected to a weak side of another switch.

Disclosed is a sound production apparatus, comprising a housing and a sound generator. A rear cavity is formed between the housing and the sound generator; the housing is provided with an opening communicated with an outer part of the rear cavity and the sound generator; the periphery of the opening is surrounded by an opening wall, and the top surface of the opening wall is configured to be sealingly connected to an external device to realize sealing of the rear cavity; a filling area is provided in the rear cavity, the filling area is filled with a sound-absorbing material, and the filling area is surrounded by an enclosing wall; at least a portion of the opening corresponds to the filling area, and at least a portion of the opening wall overlaps with the enclosing wall; a packaging part used for sealing the filling area is provided on the top surface of the enclosing wall; an annular elastic gasket having a sealing effect is provided on the top surface of the opening wall; at the position where the opening wall overlaps with the enclosing wall, the annular elastic gasket is pressed on the upper surface of the edge of the packaging part. Further disclosed is an electronic device comprising the sound production apparatus. The present invention can improve the filling volume of the sound-absorbing material, and improve the acoustic performance of the sound production apparatus.

A lens assembly is disclosed, which includes a base and a lens barrel. The base has a front edge, a back edge opposite to the front edge and a passage penetrating the front edge and the back edge. The lens barrel is disposed in the passage and includes a lens and a lens holding member holding the lens, wherein an outer surface of the lens holding member is in contact with an inner wall of the passage, and at least one of the inner wall of the passage and the outer surface of the lens holding member includes a smooth surface, arranged such that a thrust force applied on the lens barrel while assembling the lens assembly causes a sliding movement between the base and the lens barrel on the smooth surface.

A microresonator structure comprises a waveguide and a microsphere. The waveguide is of elongated cylindrical shape and includes a first section of optical transmission material and a cavity section axially aligned with the first section. The cavity section includes a first cavity and a second cavity. The first cavity is adjacent to the first section and includes a first sidewall of optical transmission material with an inner surface that tapers inward to an apex positioned adjacent to the first section. The second cavity is positioned adjacent to the first cavity of hollow cylindrical shape and includes a circumferential second sidewall of optical transmission material that abuts the first sidewall. The microsphere has a spherical outer surface and is positioned within the cavity section such that the outer surface contacts a portion of the first sidewall and a portion of the second sidewall.
