Abstract: The invention relates to the use of a light-gated ion channel for the manufacture of a medicament for the treatment of blindness and a method for expressing said cell specific fashion, e.g. in ON-bipolar cells, ON-ganglion cells, or AII amacrine cells.

Abstract: A circuit support for a semiconductor chip with a substrate made of an insulating material has a chip mounting area and a plurality of bonding pads surrounding the chip mounting area. The chip can be applied in a central area of the chip mounting area. A peripheral area surrounding the central area defines the border of the chip mounting area and it is of a far greater length than a length of the lateral edges of the chip to be mounted.

Abstract: In a biometric sensor and a method for its production, a sensor chip is provided with connecting contacts in the form of electrically conductive bumps. The sensor chip is inserted into a chip housing, the bumps making contact with corresponding connecting leads belonging to the chip housing. At the same time as this contact is made, the sensor chip is bonded adhesively into the chip housing by an adhesive layer, which surrounds the sensor field in a sealing manner.

Abstract: The invention relates to an electronic device having a multiplicity of contact bumps and an intermediate support. In this case, the intermediate support connects the multiplicity of contact bumps to contact areas of a semiconductor chip via a multiplicity of flat conductors which have contact connecting lugs exposed in a bonding channel window of the intermediate support. The contact areas are configured in the bonding channel window via the bonded contact connecting lugs of the flat conductors. The width of the bonding channel window is increasingly greater with increasing distance from the neutral point of the semiconductor chip.

Abstract: A microbiological process for the production of .gamma.-decalactone. According to this process, a culture of the fungus of a particular species of the genus Mucor is incubated with the particular substrate, which is an organic carboxylic acid ester, to produce fermentatively the .gamma.-decalactone. Exact conditions have now been discovered under which .gamma.-decalactone can be prepared in high yields. These conditions are based upon the fermentative incubation of a fungus of the genus Mucor in conjunction with the appropriate substrate in order to obtain the high yield of the desired lactone.
