摘要:
The invention concerns a piston comprising a body (10) having a guiding and sealing surface (12), a base (14) and a top (16) which has a cradle-shaped recess (18). The base (14) has a another cradle-shaped recess (22), of concavity opposite the concavity of the top recess (18).

Die Erfindung bezieht sich auf ein Verfahren zur Herstellung eines ringförmigen tribologischen Bauteils in Form einer Dichtung oder eines Gleitlagers aus einem spröden Werkstoff. Um auch bei segmentierter Bauweise die erforderliche Dichtwirkung zu erzielen, ohne dass bei der Herstellung der aneinander grenzenden Segmentflächen aufwändige Nacharbeiten erforderlich sind, wird vorgeschlagen, dass das ringförmige Bauteil aus durch Brechen eines Ringelements (10) hergestellte Segmente (12,14) besteht und dass die Segmente (12,14) derart zusammengesetzt sind, dass zueinander passende Bruchflächen (54) aufeinander liegen.
摘要:
There is disclosed a method for manufacturing a batch of sensors comprising the steps of: providing a substrate which has a plurality of conductive tracks formed thereon; electrochemically depositing an active sensing material over the substrate and the conductive tracks in a process in which the conductive tracks are part of a single electrical circuit; removing deposited active sensing material from predetermined portions of the substrate; and sub-dividing the substrate to produce a plurality of sensor units.
摘要:
A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.

The disclosure relates to a method of manufacturing and handling parts for a packaging container in that a number of tops (1) are produced in the form of a row (11) of pairwise reversed tops, whereafter the pairs (12) are separated from one another and are provided with closure arrangements. The tops (1) may be manufactured by blow moulding of an extruded hose (8) of thermoplastic material.
摘要:
A method for processing a wafer containing microelectronic mechanical devices that allows all fabrication and test steps to be performed in wafer form instead of device form. The wafer 20 is mounted in a saw frame 24 on dicing tape 22 and the individual devices 27 separated, typically by sawing, prior to completing device fabrication. The devices are left on the dicing tape during the remaining fabrication steps. Some fabrication steps may require covering the adhesive of the dicing tape with a protective cover 44. After all fabrication steps including the application of a protective overcoat and functional testing are completed, the devices are removed from the dicing tape and packaged.
摘要:
An assembly of mated moulded parts, particularly a bearing cap (10), having first and second parts (12,14) with precisely mating surfaces (28) is made by forming the first part by moulding, casting, or the like such that the mating surface of the first part is formed with at least one protrusion (30). The second part is formed in place against the first part such that precisely mating surfaces are formed with the second part enveloping the protrusion. The two parts thus formed are forced apart from each other. The protrusion may be formed with a head (34) which interlocks with the second part and which is broken from the protrusion when the parts are separated.
