摘要:
The invention concerns an implantable infusion pump for dosed emission of medicines into the human body comprising a pump chamber formed by an upper chamber portion (3) and a lower chamber portion (2), whereby said pump chamber is divided by a flexible membrane (6) into a pressure chamber (8) and a medicine reservoir (7). Refill apertures (12, 14) covered by septa (13, 15) are further provided. The septa (13, 15) are hermetically clamped by holders (4, 5). According to the invention, catch connections are used as main connections (31, 32, 33) and as ancillary connections (34, 35) for the connection of the pump components (2, 3, 4, 5), whereby the main connections (31, 32, 33) substantially support the interior pressure strain generated under normal operating load and the locked ancillary connections (34, 35) are hereby not or only nimimally brought into operation due to respective arrangement and dimensioning of the catch members. The ancillary connections (34, 35) are only activated in the case of a further pressure increase due to overload or failure of the main connections (31, 32, 33).
摘要:
A body fluid measurement apparatus for continually monitoring the body fluids produced by a catheterized patient is disclosed. The apparatus comprises a discharge hose in fluid communication with the patient, a housing that supports the discharge hose, a dripping chamber for temporarily holding the body fluid while temperature and electrical conductivity measurements are made, a force transducer for producing a signal representing the weight of the body fluid mass collected, a container for collecting the body fluid that is suspended from the force transducer, a storage cell power source, and a computer for processing a signal generated by the force transducer, for generating a timing signal, and for computing the patient's body fluid volume flow in a certain time interval. All computed measurements are sent to a display also located on the apparatus. Additionally, two angle sensors, located in two planes orthogonal to one another, provide a signal to the computer for the compensation of the inclined position of the housing and for the compensation of an erroneous measurement of the weight of the body fluids collected. In addition, a method for the automatic monitoring and recording of the corrected volume flow of body fluids produced by a catheterized patient is also disclosed.

Novel tetracyanoanthraquinodimethane polymers and use thereof. The problem addressed was that of providing novel polymers which are preparable with a low level of complexity, with the possibility of controlled influence on the physicochemical properties thereof within wide limits in the course of synthesis, and which are usable as active media in electrical charge storage elements for high storage capacity, long lifetime and stable charging/discharging plateaus. Tetracyanoanthraquinodimethane polymers consisting of an oligomeric or polymeric compound of the general formula I have been found.
摘要:
Providing a first layer of a semiconductor structure having at least one air gap between conductive lines formed in the first layer. The air gap extends into the first layer from a first surface of the first layer. A barrier dielectric material over the first surface and the air gap is selected to have a dielectric constant less than 3.5 and to provide a barrier to prevent chemicals entering the at least one air gap. An air gap can extend from a first surface of the first layer to at least a portion of side surfaces of the at least two conductive lines to expose at least a portion of the side surfaces.
摘要:
A method of sealing an air gap in a layer of a semiconductor structure comprises providing a first layer of the semiconductor structure having at least one air gap for providing isolation between at least two conductive lines formed in the first layer. The at least one air gap extends into the first layer from a first surface of the first layer. The method further comprises forming a barrier layer of a barrier dielectric material over the first surface of the first layer and the at least one air gap. The barrier dielectric material is selected to have a dielectric constant less than 3.5 and to provide a barrier to prevent chemicals entering the at least one air gap. In another embodiment, the at least one air gap extends from a first surface of the first layer to at least a portion of side surfaces of the at least two conductive lines to expose at least a portion of the side surfaces, and a barrier layer of a barrier dielectric material is formed over the exposed portions of the side surfaces of each of the at least two conductive lines.
摘要:
An intermediate product in the manufacture of a vertical multiple-channel FET device containing alternating —Si—[(SiGe)—Si]u- stacked layers is shown, as well as a process for selectively etching the SiGe layers in such a stacked layer system, and products obtained from such selective etching. Differential Ge content is added to the successive layers to provide uniform removal of the sacrificial SiGe layers.

A hydraulic system for actuating at least two operating systems of a motor vehicle has a first hydraulic medium reservoir for storing a hydraulic medium. A distribution valve is connected to the first hydraulic medium reservoir and to the operating systems of the motor vehicle. A control unit is connected to the distribution valve which is configured to distribute the hydraulic medium from the first hydraulic medium reservoir to the operating systems of the motor vehicle and to control flow of the hydraulic medium to the operating systems of the motor vehicle such that one of the operating systems has priority with regard to supply of the hydraulic medium. A first one of the operating systems is a brake device having a brake power assist unit, a brake valve, and a master brake cylinder. The brake power assist unit is connected via the brake valve to the control unit.
