摘要:
The invention relates to an empty container (1) for accommodating high-purity and ultra-high-purity, air- and/or moisture-sensitive liquid or condensable compounds, comprising a cylindrical jacket (3), a bottom (4a) and an upper end piece (4b, 4b′) at the two ends of the cylindrical jacket, an associated connection unit (2) including shut-off/multiple-way and rinsing system (5), and an associated immersion pipe (7), characterized in that the lower end of the immersion pipe (7a) protrudes into a recess (4c) (depression), which is introduced in the bottom (4a) and which is the lowest point of the bottom, and/or the lower end of the immersion pipe (7a) is tapered and is brought close to the lowest point of the bottom (4a) to within less than 2 mm by means of the tip of the tapered immersion pipe (7b) or touches the lowest point of the bottom with the tip of the tapered immersion pipe (7b). The invention further relates to the use of empty containers according to the invention for storing, handling, and/or transporting such high-purity and ultra-high-purity compounds.

The present invention relates to a process for producing an SiO2-containing insulating layer on chips and the use of specific precursors for this purpose. The invention further relates to an insulating layer obtainable in this way and also to chips which have been provided with such an insulating layer.
摘要:
A connecting strip (1) for telecommunications and mid-range communications technology includes a housing (2) and at least two contact elements (11). The contact element (11) includes a first contact (12) for the connection of wires or cables and a second contact (13) for contacting a printed circuit board. The second contact (13) takes the form of a press-fit pin contact or a tuning-fork contact. The first contact (12) is aligned towards the upper side (3) of the housing (2) and the second contact (13) is aligned towards the underside (4) of the housing (2). The first contacts (12) are arranged laterally offset from the longitudinal axis (L) of the housing (2).
