Abstract: A protection circuit for a large-scale integrated circuit includes a metal insulator semiconductor transistor (Q1) to be protected, a resistor (R1) connected between an external terminal (I) and the gate of the transistor (Q1) to be protected, a protecting transistor (Q3) having a base which is a well region of a substrate of the large-scale integrated circuit, and an auxiliary transistor (Q4) connected between the base of the protecting transistor (Q3) and a voltage source (V SS ). The auxiliary transistor (Q4) causes the base of the protecting transistor (Q3) to become a floating state when the large-scale integrated circuit is not energized by a power source (V CC ) and causes the base of the protecting transistor (Q3) to become conductive with the voltage source (V SS ) when the large-scale integrated circuit is energized by the power source (V CC ).

Abstract: A TTL/CMOS compatible input buffer circuit comprises a Schmitt trigger input buffer stage (29) and a reference voltage generator (20). In the TTL mode, the reference voltage generator (20) supplies a reference voltage (V  REF ) having a level that forces the trigger point of the Schmitt trigger (10) to a predetermined value. In the CMOS mode, the reference voltage generator (20) is disabled and a voltage equal to the power supply voltage (V  cc ) is provided to the Schmitt trigger (10). The input buffer circuit affords an enhanced input noise margin and minimizes DC power loss.

Abstract: Un différentiel variable en continu (10) met en oeuvre une transmission variable en continu (50) animée d'un mouvement de rotation par un couple d'entraînement et régulée pour faire varier le rapport de vitesse entre ses arbres de sortie. Ces derniers, qui transmettaient précédemment la puissance au moyen de la transmission, sont reliés avec une paire d'arbres moteurs tels que des essieux-moteur opposés (17 et 18) qui tournent avec la transmission sous l'effet de la puissance d'entraînement. La différenciation entre les arbres se transmet à travers la transmission par l'intermédiaire de rapports de vitesse variables qui commandent les bras du couple, les avantages mécaniques, et les rapports de sollicitation de couple. Cet agencement permet une distribution du couple en fonction des conditions détectées de roulement du véhicule. Il permet d'appliquer davantage de couple à une roue retenant la traction quand sa roue opposée patine, et il permet d'appliquer une partie plus importante du couple à des roues supportant davantage de poids ou à une roue tournant plus vite à l'extérieur d'un virage.

Abstract: Medical infusion apparatus (2) comprises a housing (4) in which a standard flexible liquid reservoir (10) is disposed. A constant-force spring applies pressure to the reservoir to force liquid out of the reservoir (10) and along a conduit to a patient. The spring (40) is energised by the opening of a lid (8) of the housing (4) which permits replacement of the reservoir (10). 
     The liquid flowing out of the reservoir (10) passes through a moulded conduit part (12) which is configured so that it is positioned at a predetermined location with respect to a flow monitor. The flow monitor injects a pulse of heat (53), and detects the rate at which the heat pulse travels along the conduit. A microprocessor (66) uses the sensed flow rate to control a stepper motor (84) which regulates fluid flow by squeezing the conduit (56) via a spring-biased member (96). The apparatus has active and standby modes in which the monitor (74) is operated respectively more and less frequently.

Abstract: A TV program recording system detects program identifying data superposed on TV signals through a detector circuit (121) and a decoder (122). To avoid complex operation for reservation of recording, trigger signals are produced from a timer unit (190) maintaining a predetermined timing, and the recording of the TV signals is initiated by a recording unit (180) via a recording control unit (170). The timer unit (190) can be easily operated and sends a memory requestto a memory circuit (140) to record said program identifying data at the predetermined timing produced from the detector circuit (121) and the decoder (122). To cope with the extension or contraction of TV programs, a comparator circuit (150) compares the program identifying data at said predetermined timing from the recording circuit (140) with said program identifying data at a subsequent timing produced from the detector circuit (121) and the decoder (122). The recording control unit (170) permits the recording unit (180) to continue the recording operation as far as a coincidence output is supplied from the comparator circuit (150).

Abstract: The frequency modulator is suitable for the frequency modulation of a radio-frequency carrier, particularly with digital modulation signals. It comprises a voltage-controlled oscillator (VCO) (3) which, in terms of its frequency-modulated output frequency, is stabilised by a reference oscillation with the aid of a phase-locked loop, comprising a frequency multiplexer (4), a Swallow frequency divider (5) controlled by the modulation signal and the radio-frequency signal, an adder (11) for the modulation voltage and control voltage, a control voltage filter (10) and a phase comparator (9). The modulation signal is fed, on the one hand, via a modulation filter (1) to a control circuit (12) for the Swallow frequency divider and, on the other hand, to a level controller (2) in front of the adder (11). As a result, the VCO is modulated with the desired frequency swing according to the instantaneous amplitude of the modulation signal, both directly by the modulation signal and indirectly due to the changeover of the Swallow frequency divider and thereby due to the control voltage. <IMAGE>

Abstract: An ultrasound apparatus has a transducer array which includes a number of individual transducer, each transducer having a channel exclusively associated therewith. In an input stage for the ultrasound apparatus, an analog stage is provided in each channel to which the echo signals for a transducer associated with that channel are supplied. This analog stage concludes with an analog-to-digital converter in each channel. The output of the analog-to-digital converter is connected to a further processing circuit in each channel for the acquisition of Doppler signals of moving target echoes. A combined ultrasound imaging device and Doppler device is thus achieved, which allows the acquisition of Doppler signals with the digital input technology of the ultrasound imaging processing circuit. This permits expansion of digital operating RF input components of imaging devices to include Doppler signal processing.
