Abstract:
A pressure transducer comprising a tubular support which is closed on one end by a semiconductor device for converting mechanical stresses into electrical signals. Current supply conductors for the semiconductor device extend through ducts in the tube wall. These current supply conductors preferably consist of cemented metal wires.
Abstract:
A gas discharge panel in which the conductors of the base plate and the upper plate are connected to said base plate and upper plate by means of an enamel.
Abstract:
A television camera tube having an elongate envelope comprising two cylindrical parts. The cylindrical part which is connected to the face plate has a larger diameter than the other cylindrical part and comprises a gauze electrode secured to a supporting ring. This supporting ring is clamped between the face plate and the neck between the two cylindrical parts by means of resilient pressure means. A circular rounding of the neck on the side of the cylindrical part with the smallest diameter is to be preferred, said rounding being covered with a conductive layer. A few dimensions are given related to the diameter of the cylindrical part of the smallest diameter. The ratio between the voltages at the gauze electrode and the conductive layer preferably is between 1.65 and 2.35.
Abstract:
A laser having a wavelength of 6,328 A is constructed from a quartz capillary which is connected by side tubes to a supporting outer tube and electrode spaces. Double conical edges are ground on the outer tube, the line of intersection of which constitutes the support for the reflector plate. The laser is of the nearly hemispherical type and single mode.
