摘要:
A controllable hydraulic oscillating slide machine includes an inner rotor arranged in a housing and having cylindrical recesses. A bearing is formed in the housing, in which a co-rotating outer rotor is mounted eccentrically to the inner rotor, the outer rotor having several pivotably suspended slide drivers that engage into the recesses of the inner rotor for rotationally driving the outer rotor by way of the inner rotor and form modifiable chambers. The slide drivers may each be coupled to a piston that is guided in a respective associated recess. A pressure level different from that in the chambers between the inner and the outer rotor may be set in the chambers delimited by the recesses and the associated pistons so that two different pressure levels may be generated and two different consumers can be supplied using the oscillating slide machine.

A method for structuring a photoresist layer includes the steps of providing a substrate on which a photoresist layer has been applied at least in some areas. The photoresist layer includes a film-forming polymer that contains molecule groups that can be converted into alkali-soluble groups by acid-catalyzed elimination reactions. The polymer further includes a photobase generator that, on exposure to light from a defined wavelength range, releases a base. The polymer additionally includes a thermoacid generator that releases an acid when the temperature is raised. The photoresist layer is initially exposed, in some areas, to light from the defined wavelength range. The photoresist layer is then heated to a temperature at which the thermoacid generator releases an acid and the acid-catalyzed elimination reaction takes place. Finally, the photoresist layer is developed.

Imaging errors in optical exposure units for the lithographic structuring of semiconductors are determined. First, a latent image of a mask is first produced in a photoactivatable layer by exposure using the optical exposure unit to be tested. After heat treating for increasing the contrast and developing the exposed resist, the latter is treated with an amplification agent which preferably diffuses into the exposed parts of the photoresist. There, it reacts with groups of the photoresist. This leads to an increase in the layer thickness of the resist in the exposed parts. A topographical image of the surface of the photoresist, which can be created, for example, by scanning electron microscopy, then indicates imaging errors by protuberances which are located outside the image of the mask. The method permits testing of optical exposure units under production conditions and thus facilitates the adjustment and the checking of all components of the exposure system used for the production of microchips.

The present invention relates a pharmaceutical composition comprising a taxane and an inhibitory compound capable of inhibiting the enzyme acetaldehyde dehydrogenase e.g. disulfiram. The pharmaceutical compositions of the invention can be used to coat medical devices such as implants. Such implant can be an expansible hollow part, having at least one opening, which consists of an elastic biocompatible material that comprises elongated micro-cavities in its surface. Medical devices coated with a pharmaceutical composition of the invention exhibit an enhanced transfer of taxane from the surface of said medical device into the target tissue.

An emergency response system capable of directing building occupants to a safe location in real-time is disclosed. The system comprises a plurality of sensors which detect and monitor an emergency condition, a central processing unit which evaluates the data, calculates accessible evacuation routes, and sends the result to output devices which provide directional information to occupants. By combining an analysis of the flow of evacuees with changes in building structural information and the evolution of an emergency condition the system combines situation-aware data with contextual information to thereby provide the best available evacuation route to evacuees. In this manner, some evacuees may be redirected to alternate evacuation routes during the evacuation process itself, thereby minimizing problems due to congestion, potential panic of the evacuees, and changes in the emergency condition while increasing the probability that evacuees will reach a safe location.

The present disclosure is a method for storing possible classes or class containers (Jars) based on usage patterns of JVMs. The classes may be stored in the memory area of the JVM that may use those most and is closest to the actual system for access. Distributed environments where memory is shared across all systems can access memory across all systems but access speed is only high close to the current system with a fast connection and bandwidth towards this memory area.

The method enables determining imaging errors of photomasks for the lithographic structuring of semiconductors. A latent image of the mask is first produced in a photoactivatable layer by exposure. After heat treatment carried out for increasing the contrast and development of the exposed resist, the latter is treated with an amplification agent which preferably diffuses into the exposed parts of the photoresist. There, it reacts with groups of the photoresist, which leads to an increase in the layer thickness of the resist in the exposed parts. A topographical image of the surface of the photoresist, which can be created, for example, by scanning electron microscopy, then indicates imaging errors by protuberances which are located outside the image of the mask. The mask layout can be tested under production conditions and the adjustment and the checking of all components of the phototransfer system used for the production of microchips is facilitated.

A method structures a chemical amplification photoresist layer, in which a photoresist layer of the chemically amplified type is brought into contact, before or after the exposure for structuring, with a base which is capable of diffusing into the photoresist layer. As a result of this treatment with the base, greater steepness and less roughness of the resist profiles are achieved in the subsequent development step.

The invention relates to a setting device for a ventilation flap (12, 12a,2b) in an air duct, particularly in a heating and ventilation system of an automobile, with an electric motor (2) executing setting movements and with a control unit (3) for the electric motor (2). In order to minimize the outlay in terms of assembly and the replacement parts to be kept available, there is provision for designing the electric motor (2) as a stepping motor activated by output signals from a control unit (3) adjacent to this stepping motor, and the control unit (3) has encoding inputs (K1, K2) for selecting the direction of rotation and/or the rotary angle.
