Patent EP-0011933-A2 (EP)
Title: Cardiac pacemaker
Inventor: STEIN MARC T
IPC: A61N1/365
Filed: 1979-11-05
Abstract: A demand pacemaker comprises sensing means for detecting heart activity. Sensed electrical signals are passed through a buffer amplifier 25 to a reversion circuit 22. Reversion circuit 22 includes two capacitors, one which follows the sensed electrical signals and one which establishes a reference level representative of extraneous repetitive noise. A differential amplifier detects the difference in the capacitor signals and produces a sense output when heart activity is detected. A blanking signal applied to the buffer amplifier 25 operates to prevent signals from passing to the capacitors of reversion circuit 22. The blanking signal may be supplied from digital circuitry and is arranged to bias the buffer amplifier into a non-conducting condition.

Abstract: A normally open, two stage solenoid actuated flow control valve having a pressure relief function, in which a poppet assembly (80) comprising a spring biased poppet (81), a range spring (116) and a spring adjusting screw (114), controls the communication of balancing fluid pressure to a primary valve member (56). The adjustment screw includes an axial extending shaft (114a) engageable with an externally extending adjustment stem (142); rotation of the stem effects concurrent rotation and axial displacement of the adjusting screw within the poppet sleeve (110). An armature (130) is disposed in axial alignment with and intermediate the stem and the poppet assembly so that the poppet assembly can be driven to engagement with its associated seat by the actuation of the solenoid (12) or by the direct axial displacement of the adjustment stem.

Abstract: An insulating film (23) of a higher dielectric constant than silicon dioxide, for example of tantalum oxide, is formed on a p-type substrate (21). The insulating film (23) contains an n-type impurity, for example phosphorus. An electrode (24), for example of molybdenum silicide, is formed on the insulating film (23). By a heat treatment carried out for example for 30 minutes at a temperature of 1000°C an n-type region (25) is formed in the p-type substrate (21) by diffusion of impurity (phosphorus) from the insulating film (23), into the surface of the substrate (21). 
     Thereby an MIS type capacitor can be provided in which the insulating film (23) has a higher dielectric constant than silicon dioxide, whereby an increased amount of electric charge can be held in a capacitor of the same size as one in which an insulating film is provided of silicon dioxide. By the provision of the n-type inversion region (25) the capacitor can be charged up to the voltage of the power source connected to the electrode (24). By the diffusion of impurities from the insulating film (23) into the substrate (21) to form the region (25), the region (25) is formed in an accurate self-aligning fashion.

Abstract: Cache class addressing controls are improved by modifying the congruence class addresses in a manner that distributes data accessed from storage pages more uniformly among the plurality of the cache congruence classes. The value of at least the lowest-order bit (19) in the external page address field in the CPU requested address is used to control the inversion of the second highest-order bit position (21) in a congruence class selection field which is obtained from the highorder part of the internal page address field in the CPU requested address. Thus a congruence class address (CCA) is generated that tends to smooth the freqency distribution of class use in a cache directory, thereby reducing the cache miss rate and correspondingly improving processor performance.

Abstract: In a thermal ink-transfer printing apparatus, a recording sheet (16) to which a picture is to be transferred and an ink film (14) having an ink layer (142B, 142C, 142M, 142Y) are passed between a thermal head (64) and a platen roller (10) so that ink of the ink film is transferred to the recording sheet in accordance with a picture pattern. The thermal head is provided with heating resistors which are arranged in a line and which selectively generate heat in response to picture signals. Thus, the ink of the ink film is selectively heated and softened or melted to be transferred to the recording sheet. The ink film and the recording sheet pass through a gap between the platen roller and the thermal head in such a manner that the ink layer of the ink film is in contact with the recording sheet. In the ink transfer, the platen roller can rotate while pressing the ink film and the recording sheet on the heating resistor array of the thermal head. A restricting roller (22) rolling on the platen roller is disposed upstream of the heating resistor array with respect to the travelling direction of the ink film. The ink film passes through a gap between the restricting roller and the platen roller to be guided in a specific path.

Abstract: a method for providing NMR images free of chemical shift artifacts, obtained from selected nuclei of a sample containing nuclei having chemically-shifted NMR frequencies is described. Non-selected nuclei of the sample are selectively saturated prior to applying an NMR imaging sequence by applying to the sample an RF pulse containing frequencies equal to the chemically-shifted frequencies of the non-selected nuclei and having a narrow frequency spectrum about the chemically-shifted frequencies. Alternatively, selected nuclei are directly excited during application of an NMR imaging sequence by applying to the sample an RF pulse containing frequencies equal to the chemically-shifted frequencies of the selected nuclei, and having a narrow frequency spectrum about the chemically-shifted frequencies so as to exclude signal contributions from the nonselected nuclei. These selective pulses are applied in the absence of the imaging magnetic field gradients.

Abstract: A plasma display system which provides rapid firing of the cells and allows high speed scanning, comprises a plurality od display cells defined by parallel cathode electrodes X,-X<sub>3</sub>) and parallel anode electrodes (Y<sub>1</sub>-Y<sub>3</sub>) perpendicular to the cathode electrodes. Controlled by switches (SX<sub>1</sub>-X<sub>3</sub>), the cells along a cathode electrode discharge simultaneously, and the discharge is either strong or weak according to the currents in the respective anode electrodes. The current in the anode electrodes is switched (SY<sub>1</sub>-Y<sub>3</sub>) according to the picture pattern to be displayed. A strongly discharging cell provides a bright discharge which is visible through the cathode electrode, and a weakly discharging cell provides a dim discharge which is masked by the cathode electrode and is therefore invisible. The weak discharge merely functions as a seed discharge for firing adjacent cells. As all of the cells function both as display cells and seed cells, rapid firing of cells and high speed scanning of litht spots along the anode electrodes are accomplished, even though no seed electrodes specifically for providing only seed discharges are used. The density of the cells, and hence the resolution of the picture, is improved, because space is not required for separate seed electrodes.
