Abstract: A new resin gas-assisted injection technique, which can achieve both bonding and surface modification of microfluidic devices. A sealing resin is injected with a surface modification agent into the microfluidic platform to fill the micron and submicron sized channels and reservoirs, as well as the gap between the platform and the lid. A gas (e.g., air or nitrogen) is then injected to replace most of the resin inside the channels and reservoirs. The remaining resin is cured (fully or partially) by ultraviolet light. By applying a masking technique, local modification of the channel surface can also be achieved through this method. Also provided are methods and structures related to micro-fluidic devices.

Abstract: A sheet slitter winder that uses a sheet slitter to slit a wide sheet into a plurality of sheets of predetermined width, and winders to wind the slit sheets onto winding cores. Touch rollers contact the winding rolls. Temporary sheet-holding means have a sheet-retaining plate that can be contacted with and separated from the touch rollers and can temporarily hold a slit sheet against an outside peripheral surface of a touch roller at a point upstream of a point of contact between a touch roller and a roll. Cutting means are used to cut widthwise across the slit sheets thus held in place.

Abstract: Method of manufacturing a piezoelectric actuator. The method includes a pre-cure step in which the adhesive is heated to a temperature below the melting point of the adhesive. A stack is formed having a piezoelectric layer and at least one supporting layer with the pre-cured adhesive therebetween. The stack is then cured to form a bonded laminate. The temperature at which the pre-cure occurs allows for the pre-stress in the piezoelectric layer to be modified without changing the material of the supporting layer.

Abstract: A ready-made technical process for manufacturing fiber-reinforced plastic building components envisions the use of a link and, optionally, a flange and/or a base using textile blanks as starting material. Initially, at least two layers of the textile blanks are positioned vis-á-vis one another, clamped in and undergo a first sewing-up process. A preform is fashioned featuring the architecture of the product that is to be manufactured, and subsequently the preform is infiltrated with resin in order to realize the plastic building component. A tension module realizes a flange on a textile preform and a sewing material holder receives a textile preform in order to implement the steps referred to.

Abstract: A method for producing a capillary bead array comprises the steps of: dispensing beads into a liquid pool, outside a capillary, having a depth of almost the same length as the particle diameter of a bead; leveling the excessive beads by moving a leveling member which is in contact with and relatively capable of be moved to the liquid pool to remove excessive beads that the liquid pool cannot contain; aligning the beads in the liquid pool one- or two-dimensionally; bonding adjacent individual beads to each other; producing a structure having the plurality of beads bonded and aligned one- or two-dimensionally; removing the structure from the liquid pool; and disposing the structure in the capillary formed of soft resin, so that the beads comprising the plurality of beads retaining the one- or two-dimensional alignment can be introduced simultaneously into the capillary.

Abstract: The invention relates to a method for attaching a semiconductor chip to an ink jet pen body and improved construction techniques therefor. According to the method a first adhesive have a cure time greater than about 15 minutes is dispensed in a predetermined pattern in one or more chip pockets of an ink jet pen body. Beads containing a second adhesive are dispensed in two or more discrete locations around an inside perimeter of each chip pocket. A semiconductor chip having chip edges is attached to the second adhesive in each of the chip pockets and the first adhesive is cured using heat or radiation. Use of a dual adhesive system improves the alignment of the semiconductor chips relative to one another until the first adhesive is completely cured.

Abstract: A method for manufacturing an optical device provides at least two sub-bodies of a base body and, at each sub-body, a surface so that the surfaces are complementary to each other and snugly fit on one another. Along at least one of the complementary surfaces, a first optical layer system is defined. The sub-bodies are joined along the complementary surfaces so as to embed the optical layer system between them and thus forming an assembled sub-body. Machining a continuous surface on the assembled sub-body and at a predetermined angle to the complementary surfaces and the embedded layer system then takes place, where the latter abut at the machined continuous surface. A second layer system is then provided along the continuous surface.
