摘要:
A novel method and placement system are configured for populating a substrate with an electronic component. The placement system has a substrate holding device for receiving the substrate, a wafer holding device above the substrate holding device serving for receiving a wafer holding frame, and a vacuum forceps holding device arranged above the wafer holding device. The wafer holding frame can receive a complete semiconductor wafer divided into electronic components.
摘要:
The present invention is concerned with proteins selected from the members of the TGF-β superfamily, which are monomeric due to substitution or deletion of a cystein which is responsible for dimer formation. The invention is also concerned with nucleic acids, encoding such monomeric proteins, vectors or host cells containing the nucleic acids as well as with pharmaceutical compositions comprising the proteins or nucleic acids encoding the proteins. The pharmaceutical compositions can be applied advantageously for all indications for which the respective dimeric proteins are useful.
摘要:
The invention provides DNA sequences encoding novel members of the TGF-β family of proteins. The TGF-β family comprises proteins which function as growth and/or differentiation factors and which are useful in medical applications. Accordingly, the invention also describes the isolation of the above-mentioned DNA sequences, the expression of the encoded proteins, the production of said proteins and pharmaceutical compositions containing said proteins.
摘要:
A method of connecting a first and second circuit device includes providing a first circuit device having a first main area and a second circuit device having a second and a third main area. A spacer device is disposed on one of the first and second circuit devices to ensure a predetermined spacing between the first and second circuit devices. An adhesive is applied to at least one of the first main area and the second main area and the first and second circuit devices are aligned and joined. The adhesive is then cured.
摘要:
A process for preparing a purified refolded monomer or dimer of a bone-derived factor, which comprises subjecting an inclusion body of a bone-derived factor produced by genetic engineering to the following steps a) to c) in sequence: a) introducing a polynucleotide encoding a bone morphogenetic factor into a bacterium, expressing said bone morphogenetic factor in the form of an inclusion body, recovering said inclusion body and treating it with a denaturing agent to obtain a solubilized monomer, b) treating the solubilized monomer without purification directly with a refolding solution to obtain a refolded monomeric bone morphogenetic factor, c) subjecting the refolded monomeric bone morphogenetic factor to purification.
摘要:
A lead frame is described which has at least one integrated electronic circuit. The integrated electronic circuit is situated in a region of a main area of the lead frame. The lead frame has at least one signal line, at least one electrically insulating plate, and an electrically conductive, grounded plate are situated. The electrically insulating plate, and the electrically conductive, grounded plate are situated, at least in sections, between the integrated electronic circuit and the signal line. A method for producing the lead frame is also described.
摘要:
The present invention concerns the use of biologically active MP52 or/and MP121 for the treatment and prevention of diseases of the nervous system or/and for the treatment of neuropathological situations which are caused by ageing of the nervous system. A pharmaceutical agent according to the invention for the treatment and prevention of diseases of the nervous system or/and for treating neuropathological situations which are caused by ageing of the nervous system therefore contains biologically active MP52 or/and MP121 as the active substance.
摘要:
The present invention is directed to novel formulations and methods for the improved delivery and administration of hydrophobic therapeutic compounds that are substantially insoluble and/or susceptible to precipitation in aqueous solution at physiological pH, including, e.g., growth and differentiation factor-5 and related proteins. Many therapeutic compounds are hydrophobic at physiological pH levels.
