A fuel cell system has a single-stage or multistage gas generation unit for producing a hydrogen-rich gas from an untreated fuel, a single-stage or multistage gas cleaning unit, at least one fuel cell and a single-stage or multistage exhaust-gas treatment unit for converting the fuel cell exhaust gases as completely as possible. At least two sub-units of the fuel cell system are connected to one another mechanically and in terms of flow by means of a connecting plate.

A plug-and-socket connection part for being fastened to a wall includes a contact housing, a guide sleeve extendable through a wall opening, a carrier, and a locking member. The locking member locks the guide sleeve, the contact housing, and the carrier together such that the guide sleeve and the carrier are connected to the contact housing in an axial direction free of play. The guide sleeve and the carrier each include a respective locking stop and the contact housing includes a flange. The locking member includes inner locking sections which are operable with the locking stop of the guide sleeve and the flange to prestress a support arrangement between the guide sleeve and the contact housing. The locking member includes outer locking sections which are operable with the locking stop of the carrier and the flange to prestress a support arrangement between the carrier and the contact housing.

A handle for a drill- and/or chisel hammer has a mount which can be fixed to the hammer. A radial grip is fixed to said mount, the grip axis of said radial grip crossing a tool axis which is defined by the position of a tool received by the hammer. A tangential grip is also fixed to the mount. Said tangential grip has a first grip section whose grip axis is tangential to the tool axis and a second grip section whose grip axis is tangential to the tool axis and essentially perpendicular to the grip axis of the first grip section.

The invention relates to a guiding cart for a manually guided tool, for example an abrasive cut-off machine, which comprises a movable frame on which a first and a second locating recess for inserting the abrasive cut-off machine are provided. A locking device is assigned to the first recess by means of which forces can be applied to the abrasive cut-off machine in the direction of the first locating recess and the second locating recess. In this way the abrasive cut-off machine can be reliably and rapidly fixed to the guiding cart after it has been inserted into the locating recesses. The insertion of the abrasive cut-off machine is facilitated by inclined inserting elements situated in the locating recesses.

Described is a method for manufacturing of carrier element modules of a thin carrier element (4) and a thereon mounted semiconductor chip (2). This method renders possible the application of chips (2) with great dimensions (macro-chips) and a wide variety of different types. A chip transfer moulding process is designed so that a minimised height--without the need for reworking--is achievable, and therefore a less costly surface mounting of the chips can be applied. The manufactured module according to the invention can be used as well as in flexible circuit boards (e.g. for cameras) or in chipcards. The method according to the present invention has a first step of putting the at least one IC (2) onto the carrier element (4), a second step of contacting the at least one IC (2) with the carrier element (4) and a third step of transfer moulding a transfer moulding compound (18) to encapsulate the IC (2).
摘要:
A photodiode having an antireflection coating for use in optical measuring devices has its antireflection coating so selected that it provides in a predetermined wavelength range an approximately constant conversion factor. The conversion of the fight power to an electrical signal is thus substantially independent of wavelength over this wavelength range.

An optical plug connector for an optical measuring device between an internal light waveguide optical fiber and an external light waveguide optical fiber maintains a distance d between the ends of the fibers which is greater than the coherence length of the light to be transmitted through the coupling. In this manner, in spite of the presence of the air gap, interference phenomena are avoided.

A process for controlling parasitic honeybee mites, such as Varroa jacobsoni, Acarapis woodi and Tropilaelaps clareae, by the use of 2-(2,4-dimethylphenylimino)-3-methylthiazoline or an acid addition salt thereof, as well as novel compositions for controlling honeybee mites, which compositions contain these active ingredients. The active ingredients are administered in physiologically compatible preparations to the bees as feed or are applied in the beehive.
摘要:
A circuit for the conversion of an electrical input signal into an optical output signal is disclosed. A portion of the main beam from a laser diode that provides the optical output is reflected to a PIN diode with a glass pane. Linearization of the electro-optical conversion process over a wide frequency range is achieved through a feedback loop. For operation at frequencies higher than that of the feedback loop bandwidth, the various conversion factors for low and high frequencies can be additionally adapted.
