Abstract: In an NMR diagnostic apparatus, it is desirable to improve S/N ratio in reception of FID signals. An oscillator (7) includes a pre-amplifier (14), a driver amplifier (15), a final power amplifier (16) and a bias control circuit (18). The operation modes of the final power amplifier (16) can be changed by controlling the biasing voltage (V GS ) to the final power amplifier (16) which is applied by the bias control circuit (18). While the selective exciting pulse (H 1 ) is applied tothe slice portion of the patient (P),thefinal power amplifier (16) is being operated in class C i.e., high gain mode. Immediately after an application of the selective exciting pulse (H 1 ) is accomplished, the operation class. of the amplifier (16) is switched to 'A' e.g., low gain mode in order to receive FID signal from the excited slice portion by suppressing noise signals.

Abstract: An implantable microinfusion pump system for dispensing medication at a prescribed infusion rate within the human body includes a hermetically sealed housing in which a power source and circuitry for actuating the pump are contained. A permanently magnetized piston is mounted for reciprocative fill and pump strokes within a pump chamber defined by a pump body member which extends between parallel-spaced walls of the housing. The body member communicates at one end with an expandable medicament reservoir adjacent one wall of the housing, and at the other end with a catheter for conveying medicament to the body. A two stage valve arrangement causes medicament to enter the pump chamber during fill strokes of short duration and to be dispensed from the pump chamber at the prescribed infusion rate during longer duration pump strokes. To minimize current drain from the power source the piston is driven through the shorter duration fill strokes by magnetic actuator windings within the housing, and through the longer duration pump strokes by magnetic attraction between the piston and a magnetic pole piece.

Abstract: To improve the precision of the analysis of alarm curves in monitoring systems for protecting objects and people and to reduce false alarms, a signal processing arrangement is specified for such monitoring systems in which an alarm curve is produced in a monitoring path formed in the microwave or infrared wave range by objects (8) to be detected in an electromagnetic radiation field (7) directed between a transmitter (5) and a receiver (6), the arrangement being so designed and constructed that an analysis device (2) having a programmable computer (13) processes and evaluates the alarm curves after conversion into digital values and also determines response thresholds and controlled variables which allow for the particular local conditions and which modify the measured data acquisition by means of a control branch for compensating for changes in conditions and for parameter drift in the measured data acquisition by means of the actuator (17). The control branch is formed by an actuator (17) controlled by a digital/analog converter (16), and the computer (13). <IMAGE>

Abstract: A presensitized lithographic plate is comprised of a support base such as an aluminum support base with an anodized surface, having a subbing layer positioned thereon which is coated with a light-sensitive layer. The light-sensitive layer comprises a diazo compound and a binder or comprises a photopolymerizable composition. The subbing layer comprises a high molecular compound containing sulfonic acid group-containing monomer units as recurring units. The subbing layer provides a lithographic plate with greatly improved shelf life. Moreover, it increases the stability of the lithographic plate such that when the plate is stored it continues to be capable of producing copies which do not have stained background areas even when the plate is stored under adverse temperature and humidity conditions.

A refractory lined heat shield (26) protects the sliding gate carrier (22) and also serves to mount a collector extension (30) when used. The slide gate (21) is provided with a metallic frame (60) which retains a monolithic refractory (80) into which erosion resistant refractory inserts or performed members (29,70) are cast. Means are desirably provided to remove the spent refractory for remanufacture thereby reclaiming the casting. Similarly in the stationary plate (20), means are provided for remanufacture and for facilitating proper orientation of erosion-resistant refractory inserts in the manufacture ofthe stationary plate. The stationary plate is symmetrical to provide full travel pressure face relationship with the sliding gate (21). Both the stationary plate (20) and slide gate (21) casting have spring pad back up reinforcements. The statutory plate desirably has means for securing a well nozzle (19) to it.

Abstract: A surface acoustic wave (SAW) device, and corresponding method, for expanding or contracting the time scale of an input signal that varies in time but is limited to a predetermined time interval. One embodiment of the invention achieves time expansion or compression by means of two Fourier transformations providing different chirp rates, and implemented in the form that includes only five SAW dispersive delay lines. In the illustrative version of this embodiment, three of the dispersive delay lines are used in conjunction with multipliers or mixers, and two are used as convolvers. Another embodiment of the invention uses only three SAW dispersive delay lines, two in conjunction with multipliers and one located between the multipliers to effect the desired time-scale change. A third embodiment of the invention employs a SAW tapped delay line and an associated set of gates to select successive data bit signals from successive output taps in the delay line. A SAW fill-in filter is used to fill in inter-bit gaps resulting from the use of the tapped delay line.
