A flexible storage (12) and dispensing package (10) for fluid material. The package (10) has a first mode of operation capable of storing the fluid material without leakage when the package is subjected to unintentional external forces and a second mode of operation capable of dispensing the fluid material when the package is subjected to external forces intentionally applied by the user. The seco...

A work head (10) has a base member (12) which is connectable to carrier means (30) of a machine for lateral movement of the work head (10) parallel to an X-Y plane of a three-axes co-ordinate system, for longitudinal movement of work head (10) parallel to the Z-axis of that system and for rotating work head (10) on an A-axis parallel to the Z-axis; link means (14) connected to base member (12) so ...

A vertically folding door or barrier construction comprises a door leaf 1, which is divided into a plurality of horizontal, folding panels or sections 2, 14, carried in lateral guides 6-8, which are located at the sides of the door opening. With the object of obtaining a reliable folding of the door leaf 1, when the door leaf is raised, and in order to allow the door leaf to be manufactured entire...

A method and arrangement for transmitting a digital signal with a low bit rate in a time section, provided for higher bit rates, of a time division multiplexed signal. At a transmitting end the first digital signal with a low bit rate is over-sampled with a first clock signal assigned to this time section. A second digital signal which results is transmitted in the time division multiplexed signal...

A silicon oxide layer is provided on the surface of a semiconductor substrate. Light is applied to the silicon oxide layer while the silicon oxide layer is removed by etching. Intensity of reflected light is detected to obtain an intensity detection signal. The time that would be required for a decrease in thickness of the silicon oxide layer through etching by half of the wavelength of the light ...
