摘要： A coupling structure for coupling optical radiation, i.e., light, between an optical fibre and an optical device, e.g., a laser diode or a photodiode. The coupling structure has an optical through-via which guides the optical radiation to or from the optical fibre. Light exiting the fibre travels through a guidance channel so it remains substantially confined to a narrow optical path that mimics the fibre core. Conversely, light enters the fibre after having traveled through the guidance channel. The guidance channel has a first core region, the “channel core”, having first refractive index surrounded by a second region, the “channel cladding” having a second refractive index smaller than the first refractive index. The coupling structure, including the guidance channel, is preferably made of semiconductor-based material, more preferably of silicon-based material. The guidance channel is preferably silicon oxide. The coupling structure further has a fibre drive-in element, which facilitates insertion and alignment of the optical fibre to the guidance channel.

摘要： Laminated sheet material 9 comprises a laminate of a polyvinyl alcohol or other water-disintegratable film 12 with a thin coextruded film comprising a melt-bondable layer 15 and an impermeable layer 14. The laminate is odor impermeable but water disposable and so can be used to form a toilet-disposable ostomy bag by melt-sealing around the edges 10 between the facing melt-sealable surfaces 15.

摘要： A process for manufacturing an integrated device includes the steps of: providing a silicon substrate on which a silicon dioxide structure is arranged and forming a trench having first and second essentially vertical walls relative to the substrate in the structure by means of anisotropic-type etching.

摘要： HB polymers, such as copolymers of hydroxy butyric acid and hydroxy valeric acid, are provided as melt extruded films having a thickness of 5 to 200 .mu.m. Sheet materials may consist of such a film or the film may be laminated with other films to increase strength or impermeability. The films are best made by co-extrusion with a thermoplastic that is substantially non-tacky upon solidification. The sheet materials are of particular value as diaper backsheets and ostomy bags. They may include a layer of non-woven material.
