摘要:
An airbag for a vehicle occupant restraint system is provided. The airbag comprising a first and a second chamber, which can be inflated for the protection of a vehicle occupant; having an outflow element with an outflow duct via which the gas can flow out of the first chamber when the internal pressure in the first chamber exceeds the internal pressure in the second chamber and which can be compressed under the action of the internal pressure in the second chamber such that an outflow of gas out of the second chamber is counteracted, when the internal pressure in the first chamber is lower than the internal pressure in the second chamber, the outflow element has a two-layer material piece and the outflow duct is formed by folding in a portion of the material piece between the material layers of the material piece.

A storage device for electrical energy with a plurality of flat storage cells for the storage and the discharge of electrical energy with opposing flat-shaped conductors, spacer elements for maintaining a predetermined space between the storage cells and a clamping means for the clamping of the cells into a stack. The spacer elements have pressure surface areas, wherein the conductors of the cells, each are clamped between the pressure surface areas of two spacer elements by the clamping means by means of force closure. In the area of opposing pressure surface areas of a spacer element, either a contacting element for establishing an electrical connection between the opposing pressure surface areas or an insulating structure is provided. The spacer elements are provided such, that the compressions between the pressure surface areas with an insulating structure and between the pressure surface areas with a contacting element, are ajusted to each other.

An airbag for a vehicle occupant restraining system is provided. The airbag comprising a first and a second inflatable area a shoulder area arranged between the first and the second area which extends in the inflated status of the airbag in the area of a shoulder and/or in an upper arm region of the vehicle occupant to be protected and has a lower thickness as the first and the second area determined in a direction vertical to the main plane of extension of the inflated airbag or comprises a recess in the airbag. The airbag is to be arranged in the vehicle such that in case of a side collision of the vehicle the shoulder and/or the upper arm region of the vehicle occupant strikes the shoulder area of the airbag.
摘要:
In a test structure for determining dielectric breakdown events of a metallization system of semiconductor devices, a built-in compliance functionality may allow reliable switching off of the test voltage prior to causing high leakage currents, which may conventionally result in significant damage. Consequently, further failure analysis may be possible after the occurrence of a dielectric breakdown event.

A laser welding head capable of producing a plurality of beams that are proficient in providing a unique keyhole. The welding head is movable through a plurality of positions relative to substrates that enables the plurality of beams to engage the substrates in a manner that welds the substrates in a variety of stack-up positions. A welding method using the welding head is also provided.
摘要:
A cooling cell, cabinet or chamber having hollow walls which have fitting at top and bottom which can be alternatively used as inlet and outlet for the fresh cooling medium and the depleted cooling medium and collected gas. In a first phase the fresh cooling medium is forced into the bottom of the hollow wall surface to drive out collected gas above the lighter phase of the previously used medium whereupon the fillings are functionally switched so that the fresh medium is introduced from above and the heavy phase of the depleted medium is discharged from the bottom to complete displacement of the latent cooling medium.

Method for near-contour surface temperature control of shell-shaped molds (14) with mold rim zones (1), wherein the temperature control of the mold (14) on a near-contour temperature control surface (4) with adjacent, web-like or wall-like separated subareas (4.i) is effected from the respective rear space (3) of the mold rim zones (1) of the mold (14) and/or the respective mold rim zone (1) of the mold (14). The shell-shaped molds (14) are designed in two or more parts with the respective mold rim zones (1). Specifically, the temperature control as cooling in the form of temperature control on the temperature control surface (4) is locally different in subareas (4.i). The temperature control surface (4) is effected in accordance with the temperature ranges of convection, bubble evaporation, partial and/or stable film evaporation of the liquid cooling fluid water.

According to the invention, electric arresters (302, 303, 402, 403) with opposite electric polarity extend from a housing of a galvanic cell (301, 401) at several points for dissipating energy stored in the galvanic cell. At other points, the housing comprises a design (304, 305, 306, 307) supporting the space-saving fastening of the storage cell or a space-saving arrangement of fastening elements (408, 409, 410, 411) for fastening the storage cell within an installation
