Abstract: The invention comprises methods and apparatus for the mass spectrometric determination of the isotopic composition of an element comprises in an analysis gas (that is, a gas comprising the element in elemental form or in the form of a simple compound, eg, nitrogen or carbon dioxide). First and second flows of a carrier gas (eg, helium) are simultaneously passed into the mass spectrometer 9, and samples of analysis gas and a reference gas are respectively introduced into the first and second flows during selected time intervals. The time intervals are selected so that mass spectrometric measurements are made on the analysis gas samples in the absence of any signal from the reference gas samples, and v.v. A preferred embodiment comprises a gas chromatograph 28, 29 through which a sample containing the element is passed, and conversion means 30 to convert the eluting sample into the analysis gas.

Abstract: In a cooling control system for controlling cooling of an engine room of an engine, a water pump and/or cooling fans are arranged within the engine room to cool same, and electric motors (201,29,30) electrically drive the water pump and cooling fans. A control unit (15) compares a temperature of the engine detected by a temperature sensor with a plurality of different predetermined values, and based upon results of the comparison, controls the electric motors for driving the cooling fans in such a manner that as the detected temperature is higher, the flow rate of cooling air flowing in the engine room is larger. The control unit is operable when abnormality occurs in sensors for sensing operating conditions of the engine, for operating the electric motors to drive the water pump and cooling fans. Alternatively, an analog circuit (152) is operable when abnormality occurs in the control unit, for operating the electric motors to drive the water pump and the cooling fans.

Abstract: In a dual-circuit brake valve, particularly a foot-operated brake valve for brake installations of vehicles, the valve mechanism of the second circuit, of the brake circuit of the front-wheel brakes, is provided with a device for holding back pressure; this device holds back the input pressure by a certain value in the lower pressure range, while, as the pressure rises, an equalization is effected between input and output brake pressure. For this purpose, there is allocated to the relay piston (43) which acts between the valve mechanism of the first brake circuit and that of the second brake circuit and actuates the valve mechanism of the second brake circuit as a function of the pressure, an auxiliary piston (49) which is integrated structurally into the brake valve and is pressed against the relay piston (43) by means of a spring (51) against the actuating force of the said relay piston. Upon valve actuation, compressed air output by the valve mechanism of the second brake circuit acts on the auxiliary piston (49) and raises the latter from the relay piston (43) in such a way that, after a predetermined pressure threshold has been reached, the holding back of pressure is cancelled. <IMAGE>

Abstract: The present invention relates to a technique for providing phone management (PM) services to personal computers (PCs) (11), which are end users of a PC-only Local Area Network (LAN) (10), by logically associating voice terminals of a separate voice and data Network (20), e.g., a Private Branch Exchange (PBX), with the PCs. To provide the PM services, a PM server device (21) is provided as an interface between the PC and PBX Networks onto which are bridged appearances of the logically associated voice terminals. The PM server device includes hardware and PM server application software that perform routing and translations between (1) PM messages of the PC-LAN which use a first PM signaling protocol, and (2) PM messages of the PBX which use a second signaling protocol. Each end user PC of the PC-LAN that is logically associated with a voice terminal on a PBX network includes PM user application software that provides a PM user interface and terminates the first PM signaling protocol. Typical PM services that can be performed at the PC are displaying calling/called party identification, retrieving and displaying messages on the PC screen, and placing voice calls from a PC-based directory.

Abstract: Encased (BOX) trench isolation structures in a silicon substrate are formed by firstly RIE etching an ONO multilayer (Oxide-Nitride-Oxide) formed on the surface of a monocrystal­line silicon substrate through a mask defining the active areas until exposing the silicon. A successive deposition of a conformable TEOS oxide layer followed by a "blanket" RIE etching, leave tapered "spacers" on the vertical etched flanks of the ONO multilayer. Through such a self-aligned "aperture" an isotropic plasma etching (round-etch) of the silicon is performed until the lateral, under-cut, etch front below the oxide spacers reaches the bottom layer of the isolation area defining etching previously conducted through the ONO multilayer. The peculiarities of the round-etch profile are thus fully exploited for more easily implanting the walls and bottom of the trench and avoiding the presence of electric field affecting sharp corners. The process maintains a precise lateral dimensiohal control and does not require special high resolution apparatuses.
