A tool for fabricating a control surface is disclosed. In various embodiments, the tool includes a first block defining a longitudinal direction running between a leading edge end and a trailing edge end; a first sidewall spaced a first lateral distance from the first block to form a first closeout channel running in the longitudinal direction between the first block and the first sidewall; and a second sidewall configured to form a second closeout channel running in the longitudinal direction, the second closeout channel disposed laterally opposite the tool from the first closeout channel.

Thermoplastic compounds include elastomer, modified polyolefin polymer including a polar functional group, and unmodified polyolefin polymer. The melt flow rate of the modified polyolefin polymer is greater than the melt flow rate of the unmodified polyolefin polymer. The thermoplastic compounds exhibit excellent bonding when overmolded onto rigid substrates such as metals, while also providing desirable aesthetic properties and good processability.

Provided is a vacuum cleaner. The vacuum cleaner includes: a driver; a suctioner configured to suck external air by the driver; a discharger configured to discharge the sucked air to the outside; and a filter including a first filter provided in a flow path between the suctioner and the discharger to separate dust from the sucked air and having a first surface, a second filter having a second surface surrounding an outer circumference of the first surface, and a joint configured to join the first surface and a seam contacting the second surface.

A composite gear includes: a first member comprising a rotation shaft portion and a disk-shaped web extending in radial directions from the rotation shaft portion; and a second member comprising at least one engaging tooth on an outer periphery thereof and provided being supported by the web so as to surround an outer periphery of the first member. A space is provided between the second member and an outermost peripheral surface of the first member in a radial direction, a space is provided between the first member and an innermost peripheral surface of the second member in a radial direction, and at least one of the first member and the second member is formed to nip another of the first member and the second member from both sides thereof in an axial direction of the rotation shaft portion.

A prosthetic socket includes a conical cup, an outer layer on the outer surface of the conical cup, and a reinforcement layer on the inner surface of the conical cup. The prosthetic socket is shapeable after being heated to a shaping temperature. The outer layer is less malleable than the conical cup at the shaping temperature, but has a higher rigidity than the conical cup at the shaping temperature and has smoother outer surface than an outer surface of the conical cup. The reinforcement layer has a higher resistance against circumferential stress than the conical cup. A residual limb or a model of a residual limb can be inserted into the preformed prosthetic socket. The prosthetic socket is then heated to the shaping temperature and molded to conform to the contour of the residual limb or the model to form a prosthetic socket.

A pack case includes: a first wall pressing a battery stack toward a second side in a stacking direction; and a second wall pressing the battery stack toward a first side in the stacking direction. At least one of the first wall and the second wall is a panel structure wall including a first metal plate, a second metal plate located outward of the first metal plate in the slacking direction and faces the first metal plate, and an interposed member interposed between and fixed to the first metal plate and the second metal plate. The interposed member has a lower density than a metal forming the first metal plate and die second metal plate.

A wiring incorporated resin pipe includes a tubular shaped sheet formed in an approximately tubular shape at an interval so that a slit is formed between both ends in a transverse direction, a wiring unit arranged in the tubular shaped sheet along a longitudinal direction of the slit in an inner side of the slit and a resin material filled in a gap formed by matching surfaces of the slit of the tubular shaped sheet and the wiring unit to thereby seal the matching surfaces of the slit of the tubular shape sheet, in which conductive wires for wiring are laid inside the wiring unit in the longitudinal direction.

A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

A method of forming at least one channel within a substrate includes coupling a fitting to a mold, and securing together the fitting and an insert via threads. A system includes a mold configured to form the substrate. The method also includes inserting a component into an opening of the fitting. Part of the component is disposed outside of the opening of the fitting, and the component is utilized to define the at least one channel within the substrate. The method further includes molding at least one material to the component and the insert to form the substrate. Furthermore, the method includes removing the fitting from the insert while the insert remains molded to the substrate.

A pipe sealing gasket is shown which is designed to be received within a raceway provided within the female, belled end of a section of plastic pipe which is assembled with a mating male pipe end to form a plastic pipe joint. The gasket is a two-component gasket having a softer, elastomeric portion and a harder, plastic ring portion. A splicing technique is used to form the softer, elastomeric portion with the harder, plastic portion being injection molded over the previously formed elastomeric portion.
