A fluid sampling apparatus for use in a hole in the earth having a rigid wall and containing a fluid comprising a flexible tubular member extendable within the hole and inflatable to a diameter effective to urge the tubular member against the rigid wall. At least one fluid pump is in communication with the tubular member and the hole for transferring fluid between the tubular member and the hole w...

A security tag used with an electronic article surveillance system for detecting the presence of the tag within a surveilled area utilizing electromagnetic energy at a frequency within a predetermined detection frequency range includes a dielectric substrate having first and second opposing principle surfaces, a peripheral outer edge, and a resonant circuit capable of resonating at a frequency wit...

The invention relates to microprocessor controlled devices, more particularly to the transferring of microprocessor addressing to the various components in the circuit. In the system of the invention, the microprocessor can direct through the address multiplexer used for controlling the DRAM memory also other circuit means connected to the same address lines, when the address multiplexer is adjust...

The prior art discloses machines which, for cooling the surface to be machined, have a gas supply line which opens into a gas outlet which is in the direct vicinity of the polishing disk. When CO2 is used as cooling gas, stoppages, which can be traced back to snow formation of the CO2, may occur in the line and in the gas outlet. In order to avoid blockages, the machine is assigned means for the s...

A surface wave device, for use in differential coherent detection in a commutation signaling communications system using N predetermined M-bit codewords, propagates surface waves for each codeword to a first coded output IDT (inter-digital transducer) comprising M parallel taps with a pitch t=T/M, the taps having phases representing bits of the respective codeword, and to a second output IDT which...

In the alignment work for centre lines involving adjustment of machine feet, often an angle fault, a so-called angle soft foot occurs between the machine feet and the foundation feet locating surfaces, which renders difficult the alignment work. With the angle fault persisting, construction tensions occur in the machine installation. - To resolve this problem a spherical underlay unit is laid as a...

The wheel unit with support and control devices (5,6) in a rest position support against a common floor plane. By a manoeuvring component (15), they can be held raised above the floor plane, as long as the lifter remains activated.

The trolling spoon has a body (1) including an external surface which is formed a wave formations (5) to increase reflection of light from it and thereby improve the trolling spoon visibility in water.

A semiconductor device, in which wiring layers are electrically isolated from each other by an insulating film which includes an amorphous carbon fluoride film insulating film containing carbon and fluorine as main components and the wiring layers are electrically connected to each other by a conductive material buried in a hole penetrating through the insulating film, is manufactured by selective...

This invention relates to a fluorine-containing amorphous carbon film with benzene rings distributed therein. The film is formed by plasma CVD while using an aromatic hydrocarbon gas and a fluoride gas as raw materials. This invention is also concerned with a semiconductor layer which features use of the fluorine-containing amorphous carbon film as an interlayer insulating film. The fluorine-conta...
