Abstract: A plurality of electric blasting caps are fired through 
the ignition system which includes a transformer (19) having a 
primary winding (17) and a secondary winding (21). The secondary 
winding (21) of the transformer (19) is connected to the resistive 
elements (53) of the blasting caps (55) through a blasting circuit

Abstract: A system is disclosed which enables signals 
to be supplied at precisely desired times in an automatic 
test system. The apparatus includes a base delay 
memory (44) which stores information representing the higher 
order bits of a time delay, while vernier memories (70, 72)

Patent EP-0371854-A3 (EP)
IPC: C23C16/04
Filed: 1989-11-22
Abstract: A method for selectively depositing 
refractory metal (for example tungsten) on the surface (15) 
of a semiconductor substrate to form an electrical 
contact, without depositing refractory metal on an 
adjacent mask layer (11). Refractory metal halide gas and 
hydrogen gas are simultaneously flowed through a 
reaction chamber to deposit the refractory metal on the 
substrate surface and to a lesser extent on the mask 
layer. Then the flow of hydrogen is interrupted to 
cause the refractory metal halide to etch the 
refractory metal which forms on the mask layer. The 
deposition and etch steps are repeated until the 
requisite thickness is deposited. The process may take 
place in a single reaction chamber, using only 
refractory metal halide gas and pulsed flow of hydrogen 
gas. A low resistivity refractory metal layer is 
produced, and damage to the semiconductor surface is 
minimized.

IPC: F26B25/00
Filed: 1990-01-10
Abstract: The invention relates to a continuous dryer for web-fed rotary offset printing machines for drying printed webs of material, furthermore to the operation of such a continuous dryer during printing and blanket washing with checking of the gaseous and vapour proportions of ink, washing fluid and burner. 
<??>According to the invention, an IR radiation path (11) is arranged in the dryer in order to measure the main concentrations of the gas/vapour proportions located in the gas chamber using IR absorption. The process followed by the continuous dryer can thus be oriented to evaporation rates of the volatile components. 
<??>In the IR absorption measurement, spectral measured values of substance vapours of the offset printing ink appear during printing and of substances of the cleaning agent during blanket washing in accordance with their characteristic band position and intensity. 
<??>In the transition from printing to blanket washing, an immediate picture is produced of the curve of the gas/vapour concentration level corresponding to the band intensities. Depending on the concentration limit, intervention in the adjustment of the flow (4), heating (2) and ventilation equipment of the dryer or targeted metering of the cleaning agent are derived. 
<??>Deflagrations in the dryer are avoided due to the lack of delay time in on-line measurement in the case of rapid adjustment reaction or precalculated adjustment. 
<??>The changing batches of printing ink are checked in respect of their substance composition by way of the measured absorption values. 
<??>The burner adjustments (16) are likewise checked, e.g. via the CO band and fuel gas bands of the mixture.
