The shell is configured to provide aesthetic features to the acoustic system.

A method of manufacturing a heat exchanger, include the steps of: (a) providing two plates configured to be assembled together, each of the plates comprising a support layer and a cap layer laminated over the support layer at least at a front side of the plate; (b) heat bonding a microporous membrane layer to one or more select portions of the cap layer on the front side of each plate such that a liquid desiccant channel is formed between the membrane layer and the front side of each plate; and (c) attaching the front sides of the plates together to form a plate pair structure by heat bonding one or more select portions of the cap layers on the front sides of the plates such that the membrane layers on the plates face each other and an air flow channel is formed between the membrane layers.

Provided are a cutting information determination method that can use a simpler process to improve yield, and a strip-shaped polarizing sheet manufacturing method using such a method, an optical display unit manufacturing method using such a method, a strip-shaped polarizing sheet, and a polarizing sheet material. A cutting position in the width direction A2, in which a polarizing sheet material MP is to be cut along its longitudinal direction A1, is determined based on the numbers of defects counted with respect to plural points in the width direction A2 of the polarizing sheet material MP. This makes it possible to determine the cutting position in such a way that a region with many defects does not fall within the cut width, so that a higher-yield cutting position can be determined. The cutting position can also be determined using a simple process in which defects are counted with respect to plural points in the width direction A2.

The described embodiments relate to a method for embedding one or more electrical components in a flexible substrate. The method includes receiving a substrate of a flexible material, wherein the substrate includes a cosmetic surface and an opposing surface. The method further includes applying a carrier form to the substrate to create a carrier assembly, wherein the carrier form includes one or more positive images representative a design to be transferred to the opposing surface of the substrate. The method further includes removing or cutting a portion of material from the opposing surface of the substrate to form a new opposing surface. Subsequently, the carrier form is removed from the substrate to reveal one or more embedding cavities extending into the substrate at the new opposing surface. In some embodiments, the embedding cavities can thereafter receive one or more electrical components.

An apparatus for manufacturing absorbent articles includes: a swinging mechanism that feeds an elastic member while swinging the elastic member along a cross direction crossing a conveyance direction of a sheet-shaped continuum constituting an absorbent article, and that disposes a part of the elastic member on the continuum; a guiding member that conveys the elastic member; a cutting mechanism that cuts the elastic member; a joining mechanism that conveys the elastic member and the continuum that are supplied from the guiding mechanism to be taken along an outer periphery of the joining mechanism; and a sheet supply mechanism that supplies a sheet member onto an end portion in the cross direction of the continuum. A tangential direction of a deviation point at which the continuum is spaced from the guiding mechanism and a tangential direction of an arrival point at which the continuum reaches the joining mechanism are coincident with each other.

A method for manufacturing a liquid-crystal display device in which at least an absorptive polarizing film is arranged on a viewing side of a rectangular liquid-crystal display panel and at least the absorptive polarizing film and a reflective polarizing film are arranged on a non-viewing side thereof, the liquid-crystal display panel having a long side and a short side and of VA mode or IPS mode is provided.

To provide a method of producing a semi-scored double-sided tape product at lower costs and with a lower defect rate. A bonded composite tape 100 is fed from a first feeder reel 310 to a first tape-up reel 320. The bonded composite tape 100 includes a tape for production use and a double-adhesive laminate of a double-sided tape type. A die cut roll 340 is used for cutting only the double-adhesive laminate of the bonded composite tape 100 into a plurality of rectangular pieces as adhesive tape segments each having an appropriate length. On the other hand, a release tape 200 is fed from a second feeder reel 410 to a second take-up reel 420. The release tape 200 comes into contact with a part of the bonded composite tape 100 that is located downstream the die cut roll 340. The adhesive tape segments are then adhered to the release tape 200.

The present invention relates to a method for manufacturing a shower tray trough, from a composite panel of the sandwich type, to which a mask is applied corresponding to a pattern cavity making it possible to imprint, in the thickness of the foam reinforcing slab of said composite panel, the desired recesses to form said shower tray trough. To that end, the top plate of the composite panel is heated locally, only at the zones corresponding to the recesses to be imprinted, so as to allow the deformation of said top plate and the arrangement of said recesses in the thickness of the foam slab.

A support for installing facing materials such as ceramic tiles on a substrate such as floors, walls and ceilings wherein the support plate has a plurality of spaced apart recesses in the plate material, with the recesses being open at the top surface and have solid sidewalls and a base, and a plurality of slots in the non-recessed portions of the plate material extending through the top surface and bottom surface, the slots joining one or more adjacent recesses. The support plate of the invention is used for tile installations between the substrate and such tile. Thin-set mortar that is used to secure the tile to the support plate flows into the recesses and into the slots forming a continuous bond between the mortar and the adjacent slots providing for a strong bond between the support plate, mortar and the tiles.

The described method of fabricating a composite engineered wood material floor board, having a top wood layer secured to a wood material substrate layer, minimizes the effect of telegraphy in the resulting floor board. The method includes selecting a top wood layer from a top surface quality wood material having a thickness of between 1 mm and 8 mm, and selecting a substrate wood material layer having a minimum thickness of 6 mm and a thickness ratio between 1:1 and 1:10 between the top wood layer and the substrate wood material layer. A plurality of transverse rectangular spaced-apart grooves are also formed in a bottom surface of said wood substrate layer. The ratio between the depth of said grooves and the thickness of the substrate wood material has an impact on telegraphy of said grooves in said top wood layer and is therefore selected accordingly.
