A hollow structure for a face mask includes an inner wall, an outer wall spaced from the inner wall to define a hollow area between the inner wall and the outer wall, and a bottom wall that couples the inner wall to the outer wall. A first portion and a second portion together define a closable opening into the hollow area. The second portion is coupled to the outer wall by a bi-stable membrane that allows the second portion to move between (1) a first, opened position in which the second portion is spaced from the first portion to allow access to the hollow area through the opening, and (2) a second, closed position in which the second position abuts the first portion to close the opening.

A mechanical coupling assembly that includes a primary substrate having at least one aperture formed therein. A secondary substrate includes at least one mechanical interlock monolithically formed with the secondary substrate. The at least one mechanical interlock extends through the aperture. The mechanical interlock includes a main body and a head portion with a transition portion connecting the main body and head portions. The main body includes a bore formed longitudinally therein about a centerline of the aperture. The mechanical interlock joins the primary substrate and secondary substrate mechanically.

A method for manufacturing a laminated iron core includes preheating a laminated body in which a plurality of iron core pieces are laminated and which includes a resin filling hole, measuring a temperature of the laminated body after preheating the laminated body, determining whether or not the temperature measured is within a predetermined range, feeding the laminated body into a molding device in a case where it is determined that the temperature is within the predetermined range, and filling the resin filling hole of the laminated body with a resin material in the molding device.

The invention is directed to a load application element (1) which comprises at least one reinforcing element (3) that comprises a layered setup from several layers of a composite material. The reinforcing element (3) is at least partially encompassed by an outer housing (2).

A composite member is provided with a bonding member made of a fiber-reinforced resin and a bracket in which the bracket is bonded to the bonding member via a resin. The bracket has a through-hole. The bonding member has a front surface side fiber-reinforced resin sheet and a rear-surface-side fiber-reinforced resin sheet. The front surface side fiber-reinforced resin sheet, the rear surface side fiber-reinforced resin sheet and the bracket are integrally bonded to each other by the resin in a state in which the front surface side fiber-reinforced resin sheet is inserted into the through-hole of the bracket to thereby enhance the bonding strength between the bonding member to the bracket.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

A liquid crystal display device, includes a display panel; a light guide plate to transfer light to the display panel; and a light source module on a side surface of the light guide plate to supply light to the light guide plate, the light source module including a light source to generate light; and a quantum dot unit between the light source and the light guide plate, the quantum dot unit extending along the side surface of the light guide plate and including a tube member filled with a resin including quantum dots, the tube member including a sealing part.

A motor includes a stationary portion, and a rotary portion having a center axis, and rotatably supported with respect to the stationary portion so as to rotate about the center axis. The stationary portion includes an armature, a circuit board arranged below the armature, and a base portion configured to support the armature and the circuit board. The armature includes a core, a coil wound around the core, and a coil end portion extending from the coil, and connected to the circuit board. The base portion includes a bearing holder, a central tower portion configured to support the bearing holder, and a wall portion surrounding the circuit board at a radial outer side such that a radial gap is defined between the circuit board and the wall portion. The circuit board includes a through-hole passing through the circuit board in an axial direction at the center axis, and at least one exhaust hole passing through the circuit board in the axial direction. The central tower portion is arranged radially inside of a wall of the through-hole. A filler material is arranged on upper and lower sides of the circuit board. The radial gap and the at least one exhaust hole communicate with each other through an axial space between a lower surface of the circuit board and an upper surface of the base portion. The at least one exhaust hole includes a first exhaust hole extending in a radial direction, and a second exhaust hole extending in a circumferential direction from a radial end portion of the first exhaust hole. The coil end portion is arranged in the second exhaust hole.

A fibre reinforced composite product can be made by first forming a scaffold structure (400) with a set of tubes (408) running within the product interior, using a digital printing process. Using a carrier fluid, the tube lumens are invested with fibres and then matrix material. The carrier fluid may enter through the end of a tube connecting with an input manifold (920) and exit the tube radially via a capillary (904, 908) which runs alongside the tube.

Method for the production of a 3D printed object (100), wherein the method comprises (i) a 3D printing stage, the 3D printing stage comprising 3D printing a 3D printable material (110) to provide the 3D printed object (100) of printed material (120), wherein the 3D printing stage further comprises forming during 3D printing a channel (200) in the 3D printed object (100) under construction, wherein the method further comprises (ii) a filling stage comprising filling the channel (200) with a curable material (140) and curing the curable material (140) to provide the channel (200) with cured material (150), wherein the cured material (150) has a lower stiffness than the surrounding printed material (120).
