20150298264 | ASSEMBLY HAVING AT LEAST TWO CERAMIC BODIES JOINED WITH ONE ANOTHER, ESPECIALLY A PRESSURE MEASURING CELL, AND METHOD FOR JOINING CERAMIC BODIES BY MEANS OF AN ACTIVE HARD SOLDER, OR BRAZE - An assembly comprising: two ceramic bodies, which are joined by means of a joint of an active hard solder, or braze, wherein the active hard solder, or braze, has a continuous core volume, which is spaced, in each case, from the ceramic bodies by at least 1 μm, and an average composition C | 10-22-2015 |
20150063767 | METHOD AND DEVICE FOR REDUCING MODE INSTABILITY IN AN OPTICAL WAVEGUIDE - The invention relates to a method and corresponding devices for reducing mode instability in an optical waveguide ( | 03-05-2015 |
20140083597 | METHOD FOR JOINING SUBSTRATES - The invention relates to a method of joining substrates. It is the object of the invention in this respect to join substrates of substrate materials together without having to exert an increased effort for a coating with additional coating processes to be carried out and to be able to achieve a good quality of the join connection in so doing. In the method in accordance with the invention a pretreatment of at least one join surface of a substrate to be joined is carried out in low pressure oxygen plasma prior to the actual joining. On the joining, a contact force acts on the substrates to be joined in the range 2 kPa to 5 MPa and in this process a heat treatment is carried out at an elevated temperature of at least 100° C. and at under pressure conditions of a maximum of 10 mbar, preferably <10 | 03-27-2014 |
20120236400 | METHOD FOR PRODUCING AN OPTICAL ASSEMBLY HAVING AT LEAST TWO OPTICAL FUNCTIONAL SURFACES, AN OPTICAL DEVICE AND UNIT FOR CARRYING OUT THE METHOD - The invention relates to a method for producing an optical assembly, comprising at least two optical functional surfaces arranged in a fixed positional relationship to one another on a common supporting structure, wherein by means of a processing machine, in various process steps, at least two optical functional surfaces and at least one reference structure having a defined and measurable relative position to the optical functional surfaces are produced. The supporting structure remains rigidly connected to the processing machine until said process steps have been completed, and wherein the optical functional surfaces are then measured relative to the at least one reference structure, and any deviation from a target shape and target position is determined, after which said process steps are repeated at least once with modified actuation of the processing machine. The invention further relates to an optical device comprising an optical assembly produced in this way and to a unit for carrying out such a method. | 09-20-2012 |
20110222178 | ADAPTIVE DEFORMABLE MIRROR FOR COMPENSATION OF DEFECTS OF A WAVEFRONT - The present invention relates to the production of an adaptive deformable mirror for compensation of defects of a wavefront. | 09-15-2011 |
20090142809 | Method for Cleaving Cervimycin Monoesters - The invention relates to a method for cleaving cervimycin esters. An object of the invention to convert in a simple manner the cervimycin esters which are less active but formed in larger quantity into the highly active cervimycin K that occurs as a minor component in the preparation by fermentation, is achieved by preparing unesterified cervimycins from cervimycin esters with di- or monomethylated malonic acids, by ester cleavage effected by at least one esterolytic enzyme at temperatures of 20° C. to 75° C. and a pH of pH 5.0 to 10.0, preferably pH 6.0 to 9.0. | 06-04-2009 |
