Patent ES-354707-A1 (ES)
Title: Reactor cooling system
IPC: G21C9/012
Filed: 1968-06-05
Abstract: An emergency cooling system for a boiling water reactor comprises a first auxiliary steam line 23 which includes a valve 24 operated by a pressure-sensitive unit 25 set to open valve 24 at a predetermined pressure above the normal operating pressure in the pressure vessel 10. After-steam from an emergency shut-down, i.e. steam produced for some time after shut-down due to delayed neutrons, heat stored in the nuclear fuel and radio-active decay of fission products, is removed by passing it through the valve 24 and line 23 to a sparger 27 beneath the surface of the water in a pressure suppression vessel 26. The vessel 26 may be provided as a component of a pressure suppression system designed to condense the escaping steam in the event of a major rupture of the pressure vessel 10 or the primary lines within the containment building. A second auxiliary steam line 28 includes a valve 29 operated by a control unit 30 responsive to the liquid level of the coolant in the pressure vessel 10. When the liquid drops below a predetermined level the valve 29 is opened to apply steam to a steam-operated motor or turbine 31, the exhaust from which is condensed in the suppression vessel 26. The turbine 31 drives a pump 32 which supplies make-up water to the pressure vessel 10 from any suitable coolant reservoir, e.g. a storage tank 33 and/or the vessel 26. During a normal shut-down, the after-heat is accommodated by closing a valve 21 to the turbine 15 and opening a by-pass valve 22 to apply the after-steam directly to a condenser 17, the condensate being returned by a feedwater pump 19 to maintain the coolant level in the pressure vessel 10 in the normal manner.

Title: High heat dissipation solder-reflow flip chip transistor
IPC: H01L23/485
Filed: 1972-09-14
Abstract: An improved method of flip-chip mounting a semiconductor device, such as a transistor, on a pattern of electrical conductors carried on an insulating substrate, comprising providing the device chip with a glass protective layer and on the glass layer metallized bonding pads adjacent to the corners of the chip. Each of the bonding pads includes a relatively wide portion adapted to contain a relatively high mound of solder, and a second portion of a relatively narrow width capable of holding only a thin layer of solder. The thin solder layers overlie heat-generating P-N junction portions of the device. The conductors on the substrate have solder-wettable portions of larger areas than the bonding pads on the chip. Solder balls are placed on the wide portions of the bonding pads and melted to reflow the solder. The chip is then placed face down over the conductors on the substrate and the solder is again reflowed so that the relatively high mounds collapse to the thickness of the thin solder layer portions and the relatively thin solder layer portions are joined directly to the substrate conductors.

Title: Loudspeaking telephone station circuit
IPC: H04M1/60
Filed: 1973-03-21
Abstract: Disclosed is a circuit for providing voice controlled switching for a loudspeaking telephone station. The circuit is generally bistable and in one approach, it is possible for a small amount of bias to be inserted in the circuit to restore it to its transmit mode in the absence of external signals. In operation, a comparator continuously compares the transmit signals against received signal to determine in which mode the circuit should operate, i.e., continue in the operating mode or switch to the other mode. Once in a mode, either transmit or receive, an artificial signal gain is added to the main signal fed to the comparator to prevent oscillatory switching. The actual signal plus the artificial signal must be outweighed by the signal on the other path to effect a switchover.
