Abstract: Each memory cell of an electrically-programmable semiconductor memory has a field-effect transistor (5,6,11,12) with a charge-storage region (11). Efficient and fast injection (18) of hot carriers into the charge-storage region (11) is achieved by vertical punch-through of a depletion layer (1 min ) to a buried injector region (2), by application of programming voltages (Vb and Vd) to a control gate (12) and to the surface of the punch-through region (1). Non-injected carriers (19) are removed via at least the transistor drain (6) during the programming. A well-defined punch-through region (1) can be obtained with a higher-doped boundary region (3) at at least one side of the punch-through region (1) to restrict the lateral spread of the depletion layer(s) and prevent parasitic connections. This permits closer spacing of the injector region 2 to other regions of the memory cell, e.g. source and drain regions (5 and 6), and the injector region (2) may adjoin an inset insulating field pattern (29). A compact cell array layout can be formed with a common connection region (8) for the injector regions (2) of two adjacent cells and for either a source or drain region (5 or 6) of four other adjacent cells. The control gate (12) and an erase gate (14) may both be coupled in the same manner to the charge-storage region (11), and the cell can be operated with complementary voltage levels for writing and erasing. A feed-back mechanism with the start of injection from the punch-through and injector regions (1 and 2) can provide a well-defined charge level limit for the erasure.

Abstract: An exercise-responsive cardiac pacemaker is provided which physiologically controls the stimulation rate of a heart by sensing the venous blood temperature in the right ventricle of the heart. A temperature sensing means which includes a thermistor produces an output signal which is sent to an algorithm implementing means for implementing the output signal by an algorithm which represents the mathematical function between venous blood temperature in the right ventricle and heart rate in a normally functioning heart. The algorithm implementing means produces an output signal which is variable between a maximum and minimum level corresponding to the desired maximum and minimum levels of heart rate in a normally functioning heart. The algorithm implementing means is also programmable by telemetry after implantation. A cardiac pacemaker is connected to the algorithm implementing means and is responsive thereto in order to variably control the stimulation rate of the heart.

Abstract: Disclosed is a restore circuit for restoring an integrated semiconductor storage array having storage cells consisting of bipolar transistors. The restore circuit includes a reference voltage generator, an impedance converter, and switches to connect the reference voltage generator and the impedance converter to the storage array. The reference voltage generating circuit includes a current source and at least one reference storage cell identical in construction to the storage cells of the array. The reference voltage generating circuit provides a reference voltage to the impedance converter which supplies a second reference voltage to the array at a greatly reduced impedance. The equivalent circuit of the storage cells is that of a capacitor in parallel with a diode. Thus, the impedance converter provides an initial surge of capacitive current which restores the cells, followed by a standby current which is a function of the diode characteristics of the cell equivalent circuit.

Abstract: In a centrifugal pump containing a sealing shroud the pump impeller is mounted only radially for rotation on a stationary axle or shaft. The stationary axle or shaft is fixed in the suction connection by means of wing rib supports or ribs and possesses an equalizing channel which connects the pump chamber portion at the rear of the pump impeller with the suction connection. This pump chamber portion at the rear of the pump impeller is connected with the delivery or pressure connection, whereas the pump chamber portion at the front side of the pump impeller is also connected with the suction connection as well as with the delivery or pressure connection. Advantageously, throttling rings are provided for self-metering throughflow throttling, depending on the axial position of the pump impeller. Additionally, the throughflow can be regulated by a throttling screw which is provided for the equalizing channel. In this way the pump impeller requires no axial or thrust bearing and can automatically adjust itself to variable requirements within a predetermined range.
