摘要:
A process and device are disclosed for perforating and/or partially cutting printed laminated composite materials by means of laser beams from at least one laser arranged in a laser station. In order to minimize equipment costs, in particular for the control of the perforation and/or partial cutting processes, without having to renounce to an exact positioning of the perforations and/or partial cuts, a process is disclosed characterized by the following steps: the laminated composite material web is cut into individual blanks (1) according to the printed image and/or folding pattern; the blanks (1) are transported to the laser station; and the perforations or partial cuts are carried out in the stationary blank (1). Also disclosed are means for carrying out the process.
摘要:
In a method for mounting and finishing a valve seat ring in an operational position of a receiving bore at the entrance of a gas channel of the cylinder head of an internal combustion engine consisting of a light alloy, an annular body with a central opening is manufactured by powder pressing and sintering. A roller burnishing tool is positioned within the central of the annular body. The annular body is inserted into the receiving bore with the aid of the roller burnishing tool such that the annular body is positioned with play relative the inner wall of the receiving bore. The annular body is radially expanded by roller burnishing with the roller burnishing tool such that the annular body positive-lockingly engages the inner wall of the receiving bore and is compressed to a selected finish size of ready-to-use density.
摘要:
An optofluidic platform is constructed so as to comprise a planar, liquid-core integrated optical waveguides for specific detection of nucleic acids. Most preferably, the optical waveguides comprises antiresonant reflecting optical waveguide (ARROWs). A liquid solution can be prepared and introduced into the optofluidic platform for optical excitation. The resulting optical signal can be collected at the edges of the optofluidic platform and can be analyzed to determine the existence of a single and/or a specific nucleic acid.
摘要:
A chip-scale optical approach to performing multi-target detection is based on molecular biosensing using fiber-optic based fluorescence or light scattering detection in liquid-core waveguides. Multiplexing methods are capable of registering individual nucleic acids and other optically responsive particles, and are ideal for amplification-free detection in combination with the single molecule sensitivity of optofluidic chips. This approach overcomes a critical barrier to introducing a new integrated technology for amplification-free molecular diagnostic detection. Specific examples of liquid-core optical waveguides and multi-mode interferometers are described; however, they can be implemented in a number of different ways as long as a series of excitation spots is created whose spacing varies with the excitation wavelength.

The present invention relates generally to a process for the production of a container surrounding an interior, comprising the steps a. provision of a planar composite comprising i. a carrier layer, ii. a barrier layer of plastic joined to the carrier layer, iii. at least two layers of thermoplastic plastic KSa and KSw which are provided on the side of the barrier layer of plastic facing away from the carrier layer, at least one of the at least two layers of plastic being a plastics mixture of at least two plastics, b. folding of the planar composite to form a fold with at least two fold surfaces adjacent to one another and c. joining of respectively at least a part region of the at least two fold surfaces by heating the part region to form a container region, at least one of the at least two layers of thermoplastic plastic in step b. having a temperature which is below the melting temperature of this layer of plastic, and a container obtainable by this process.
摘要:
To register a communications device (UE1) in a communications network (CN), one or more temporary communications addresses (NI1, NI2) are negotiated between the communications device (UE1) and at least one registration unit (AV1) of the communications network (CN), the temporary communications addresses being valid only for a predeterminable utilization period (ZT1, ZT2). The temporary communications address (NI2) concerned is registered by the registration unit (AV1) for this utilization period (ZT2).
摘要:
An optical waveguide is provided comprising a non-solid core layer surrounded by a solid-state material, wherein light can be transmitted with low loss through the non-solid core layer. A vapor reservoir is in communication with the optical waveguide. One implementation of the invention employs a monolithically integrated vapor cell, e.g., an alkali vapor cell, using anti-resonant reflecting optical waveguides, or ARROW waveguides, on a substrate.
