摘要:
The present invention relates to a cover for covering one or more sample(s) that are suitable to avoid or minimize evaporation and/or condensation of any vaporizable substance that may be present in the sample(s) or reaction mixture(s), in particular evaporation of substance at the fringes of a vessel or an array of vessels or condensation of a substance on the lid of a reaction vessel or a plate/block containing the sample(s) and/or a cover. This is achieved by providing a device comprising, among others, a force distribution unit that comprises at least one medium or material that is unable to withstand a static shear stress and deforms continuously under the action of a shear force.

An anti-skid spike which may be applied to an embedded opening on a running surface of, for example, a tire, having an insert piece and a base body with a molded flange and a recess for housing the insert piece. According to this invention, material and shape combinations not previously applied or possible can be achieved, whereby a housing selection is formed on the base body, at least partly enclosed by at least one sleeve piece and, in an assembled state, the sleeve piece is arranged at least partly in the region around the recess.

The invention relates to the field of materials sciences and relates to a method such as can be used, for example, for producing molded articles from metallic glasses. The object of the present invention lies in disclosing a method and an apparatus in which a good mold filling during casting is achieved in addition to high cooling rates. The object is attained by a method in which a metal-containing melt is introduced into an electrically conducting casting mold, the metal-containing melt and the mold being connected in an electrically conducting manner to the outputs of the same voltage source during the introduction into a casting mold, so that a preset current flows through the boundary interface between the melt and the mold. The object is furthermore attained through an apparatus in which there is an electrically conducting connection to a voltage source between a metal-containing melt and an electrically conducting mold for the melt.

摘要:
A mechanism controller for controlling power to motors of a mechanism having several motors, such as a robot. Each motor has a resolver for indicating the motor position. A driver unit is associated with each motor to supply power to the motor. Each driver unit includes a monitoring unit to monitor indications from the resolver of the associated motor. In one embodiment a control unit is connected to the driver units in a series circuit to control power to the motors and to receive the monitored indications from the monitoring units. In a second embodiment, the control unit is connected to the driver units in a ring circuit, rather than in a series circuit. Preferably, each driver unit also includes a memory device, and the control unit can send commands to the driver units and receive data from the driver units in sets equal in number to the number of driver units so that the commands and data do not need to include the addresses of the specific driver units. Alternatively, the commands and data can include a driver unit address so that the commands and data can be individually sent, rather than sent in sets.
