A process is provided for producing a composite component having a first component element and a second component element, which are connected with one another by an adhesive connection. The process includes forming an adhesive cavity by applying thermally active plastic material to an adhesive connection side of the first component element and/or to an adhesive connection side of the second component element; arranging the first component element on the second component element, wherein a gap is formed between the adhesive connection side of the first component element and the adhesive connection side of the second component element, and supplying of heat in such a manner that the thermally active plastic material expands and forms a boundary in the gap between the first component element and the second one. The process further fills the formed adhesive cavity with an adhesive for the permanent connection of the first component element with the second component element.

A microfluidic circuit element comprising a microfluidic main channel and nano interstices is disclosed. The nano interstices are formed at both sides of the main channel and are in fluid communication with the main channel. The nano interstices have a height less than that of the main channel, gives more driving force of the microfluidic channel and provides stable flow of a fluid. The microfluidic circuit element may be made from a plastic material having a contact angle of 90 degrees or less. The microfluidic circuit element is particularly useful when filling a liquid sample to the channel which is empty or filled with air and shows greatly improved a storage stability.

An illumination device is provided and has a light guide plate, a light source and a light modulator, wherein the light modulator has a pair of transparent substrates a pair of electrodes and a light modulator layer. The light modulator layer includes a first region being changed between a transparent state and a scatterable state depending on intensity of an electric field, and a second region being more transparent than the first region in a scatterable state at an electric field having a certain intensity, the electric field being applied when the first region is changed between the transparent state and the scatterable state, and an occupancy rate of the first region in the light modulator layer is increased with increase in distance from the light source.

A method is provided for laminating optical substrates and in particular for manufacturing a thin combiner for an optical display that preserves the flatness of the component parts and ensures an even separation of layers, in particular an optical substrate and a thin cover plate that is to be bonded to the substrate. In the method, spacer particles in a predetermined size range are included within a glue layer at a required density to ensure cover plate flatness and uniform separation during assembly.

A bonded body having high dimensional accuracy and manufactured easily without problems which occur in the solid bonding method and a method of manufacturing such a bonded body are provided. The bonded body includes a first base member having a first bonding surface; a second base member having a second bonding surface; and a bonding film through which the first base member and the second base member are boded together, the bonding film having two surfaces each making contact with the first bonding surface and the second bonding surface, the bonding film including a silicone portion containing a silicone material composed of silicone compounds and a plurality of gap members that regulate a distance between the first base member and the second base member, at least a part of the gap members provided in the silicone portion. In such a bonded body, energy for bonding is applied to a region of at least a part of the bonding film to develop a bonding property in a vicinity of each of the surfaces of the bonding film corresponding to the region so that the first base member and the second base member are bonded together through the bonding film due to the bonding property.

An optical apparatus is disclosed which is capable of adjusting spacing between an optical member and a holding member or between optical members virtually without changing irradiation conditions of laser, and thus achieving reduction of joining time and improvement of positional accuracy at low cost. The apparatus includes an optical member, a thermomelting member, a spacing adjustment member and a holding member in this order. A first weld portion welding the spacing adjustment member and the holding member is formed therebetween, the first weld portion having been formed by heat generation of the holding member irradiated with the laser light transmitted through the optical member, the thermomelting member and the spacing adjustment member, and a second weld portion welding the spacing adjustment member and the optical member is formed therebetween, the second weld portion having been formed by the thermomelting member melted with heat transferred from the holding member.
