Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank.

Disclosed are embodiments of a versatile storage bag and methods of making same. The versatile storage bag may have first and second sidewalls, a double-locking closure mechanism with a first closure element extending along the first sidewall and a second closure element extending along the second sidewall, each closure element having a channel and an elongated member configured for interlocking with one another. A double-seal along three sides of the first sidewall and the second sidewall form a gusset between two seals, leaving an opening through the double-locking closure mechanism. Corner seals may be formed at the corners of the first and second sidewalls, further reinforcing the double-locking closure mechanism for an airtight and hence waterproof seal. The versatile storage bag may be made of a food-grade polyethylene vinyl acetate blend, approximately 90% or less ethylene vinyl acetate and approximately 10% or less polyethylene.

A component joining structure having: a first component provided with a joint portion for joining components together; a second component formed from a resin material in which fibers are oriented in multiple directions; and a joined portion that is integrally formed to the second component using a resin material, that is in close contact with the joint portion and is joined to the joint portion, and in which the fibers are oriented in multiple directions.

A method for manufacturing a thermoplastic composite product includes: providing a first and second thermoplastic composite component made from a consolidated stack of thermoplastic composite plies, said first and second component having a first and second ply drop off, respectively. The first and second components are positioned such that the first ply drop off and the second ply drop off are aligned, and the first and second components are fixedly connected by means of heating. The stacks of plies for the first and second components are constructed by stacking the plies in a stacking direction wherein the plies are arranged such that plies at a different position along the stacking direction are laterally offset relative to each other for the purpose of forming the first ply drop off and the second ply drop off, respectively, before consolidating.

The present application provides an ultrasound probe comprising a housing that includes a coupling interface having a sinusoidal geometry. The housing is formed by a first body (300) and a second body having opposite and corresponding sinusoidal geometries. The first body includes a first proximal portion (105) and a first distal portion (107). The first proximal portion comprises a first sinusoidal shape (326). The second body includes a second proximal portion and a second distal portion. The second proximal portion comprises an opposite second sinusoidal shape. The first body and the second body are coupled to form a handle having a sinusoidal interface. Further, the first distal portion and the second distal portion form a head portion at which the ultrasound transducer assembly is disposed.

A battery state detection device includes a casing (8) and a lid part (24). The casing (8) includes a board storage space (23) that stores a circuit board. The casing (8) includes an open mouth through which one side of the board storage space (23) is opened. The lid part (24) closes the open mouth of the casing (8). The lid part (24) is provided with a tapered surface (77). The casing (8) is provided with a contact portion (78) that can be in contact with the tapered surface (77). In a state where the tapered surface (77) and the contact portion (78) are in contact with each other, ultrasonic welding between the casing (8) and the lid part (24) is performed.

A gear housing for an epicyclic gear set, the gear housing including a hollow wheel having internal teething and a first front end with a first front-side joining surface; a housing cover having a second front end with a second front-side joining surface for longitudinally axially covering the hollow wheel; and a bonded connection for connecting the first front end to the second front end through the mating of the first and second front-side joining surfaces, at which the hollow wheel and the housing cover are connected to each other by a bonded connection, in particular, by heated tool welding, infrared welding, ultrasonic welding, or rotary friction welding.

A housing includes a first surrounding wall connected around a base wall. The first surrounding wall has a first joint portion opposite to the base wall, a first outer surface and a first inner surface. The first outer and inner surfaces extend from the first joint portion toward the base wall. The first joint portion is stepped and has a first projecting portion adjoining the first outer surface, and a first shoulder portion indented from the first projecting portion and proximal to the first inner surface. The first shoulder portion has a plurality of parallel spaced-apart ribs protruding therefrom in a same direction as the first projecting portion. Each of the ribs has a tip that does not extend beyond a top end of the first projecting portion.

A resin board structure includes a first member including a first metal film and one thermoplastic resin layer or a stack which includes two or more thermoplastic resin layers, and a second member including a second metal film. The first and second metal films are bonded together, and at least a portion the first metal film and at least a portion of the second metal film overlap each other. The first and second metal films are metallurgically bonded at an interface between the first metal film and the second metal film. The first member includes a first junction resin covering portion defined by a portion of a thermoplastic resin layer and overlapping a portion at which the first metal film and the second metal film overlap each other, and the first junction resin covering portion includes an uneven surface to reduce or prevent slippage due to ultrasonic vibration.

An article with a component joined with stitchbonding to a nonwoven textile formed from a plurality of thermoplastic polymer filaments. The nonwoven material, component, yarn, and stitch pattern can be optimized using disclosed structures and components to provide the article with desirable characteristics such as increased tensile and tear strength, improved aesthetics, moisture resistance and to limit or modify the stretch of the article in one or more directions and the like. A variety of products, including apparel (e.g., shirts, pants, footwear) may incorporate the article. In some of these products, the nonwoven textile may also be joined to the component with other bonding structures such as heat bonding, adhesives and the like.
