A connection tube is provided supplying cooling medium into the individual housing sections. A series connection of the cooling medium circulation is produced between a first side part in direction of cooling medium flow and a first housing part as well as between a center part and a second housing part respectively having a closure disc installed therewith. Perforations are provided for pressure equalization in the closure discs. For production of a parallel connection of cooling medium circulation between a first side disc in a direction of cooling medium flow and a first housing part there is installed a shutter and further shutters are provided between the first housing part and a center part as well as between the center part and a second housing part in flow direction and between a second housing part and a second side part.

Abstract: A high speed low power linear two micron CMOS full differential operational amplifier has a pair of output cascode stages (44, 45) each providing a respective differential output with rejected common mode signals. The amplifier comprises an input differential amplifier stage (72) driving a pair feedback current mirror loads (18, 20) each cross connected to the pair of cascode output stages providing the differential outputs. Current domain operation provided by current mirror arrangements (34,35) enables fast operation of the full differential amplifier. Each output cascode stage comprises four stacked transistors including two signal transistors and two dynamically biased pass transistors. The feedback current mirror loads (18,20) and the cascode output stages (44, 45) provide the amplifier with single gain stage respecting each differential output thereby reducing the need for large compensation capacitors while improving the dynamic range of the two differential outputs. The gain of amplifier is ninety decibels with a frequency bandwidth of fifth megahertz and with low power dissipation at two milliwatts. The amplifier also comprises two feedback differential stages (62, 64) receiving a single combined common mode signal (60) formed the two differential outputs. Each feedback differential stages then drives a respective pair feedback current mirror loads (78,80,82,84) which provide negative feedback signals to the output cascode stages (44, 45) whereby common mode signals are rejected at the differential outputs.

Abstract: The process brazes refractory workpieces which have to withstand high temperatures after brazing. It involves (a) brazing the two pieces at a temperature T1 using a brazing alloy fusible at T1 (e.g. a Pd-Ag alloy), having two constituents C1 and C2, one of which, C1 (Pd), can be alloyed with one of the basic refractory metals in the workpieces by forming an alloy fusible at a higher temperature, and the other, C2 (Ag), can be removed by volatilization; and (b) heat treating the pieces under vacuum to remove C2 (Ag) so as to obtain a joint brazed with an alloy having a higher melting point. The constituent C1 (e.g. palladium), when combining with the basic refractory metals (e.g. molybdenum, tantalum or niobium), preferably has a phase diagram with a peritectic point as shown in the figure. <IMAGE>
