A dishwasher includes a number of spray arms, a circulation pump with a pump housing, an impeller, a suction port, and a number of discharge ports on the pump housing. The discharge ports are associated with the spray arms. A water diverter is located on a delivery side of the pump and generates a flow leading from the suction port selectably to one or more of the discharge ports. The water diverter includes a blocking element having a number of diaphragm openings positionable to one or more outlet positions by a drive via a rotation of the blocking element in a circumferential direction.

A method for mounting semiconductor chips includes the steps of: a) providing a semiconductor chip having a surface that has a diaphragm region and a peripheral region, the peripheral region having a mounting region; b) providing a substrate which has a surface having a recess; c) mounting the mounting region of the semiconductor chip using a flip-chip technique onto the surface of the substrate in such a way that an edge of the recess lies between the mounting region and the diaphragm region; and d) underfilling the mounting region using an underfilling component, the edge of the recess being used a demarcation region for the underfilling component, so that no underfilling component is able to get into the diaphragm region. Also provided is a corresponding semiconductor chip system.

The invention relates to an asymmetric progressive safety gear, a gear body thereof is arranged at a car or a counterweight of an elevator, a guide track passes through the gear body, the guide track is taken as the boundary, a sliding block is inserted between the upper side and the lower side of the gear body on one side in a sliding manner, a friction plate is arranged on the inner side surface of the sliding block, the inner side surface of the friction plate is parallel to the guide track, and a spacing is kept; the sliding block is fixedly connected with one end of a U-shaped leaf spring; a moving wedge block is inserted between the upper side and the lower side at the other side of the gear body in a sliding manner, a pressing plate with a tilted inner side surface is respectively fixedly connected on the inside and the outside of the moving wedge block, and the moving wedge block is fixedly connected with the other end of the U-shaped leaf spring; a roller row is arranged between the moving wedge block and a sliding wedge block, the inner side surface is parallel to the guide track of the elevator, and a spacing is kept; the sliding wedge block is fixedly connected with a transmission mechanism, the transmission mechanism is controlled by a speed limiter to act; and a reset part is arranged between the moving wedge block and/or the sliding block and the gear body. The asymmetric progressive safety gear can prevent the transverse movement of the elevator car when the car or the counterweight of the elevator stops working, the size is small and the weight is light.

A hinge plate accommodation element for attaching a hinge plate has a holder bracket that has a first shank for attachment on the frame side and an angled short shank, a bracing plate that is connected with the short shank of the holder bracket, so as to pivot, a pressure plate that is disposed on the bracing plate with binding screws, and can be adjusted relative to the bracing plate by means of activation of the binding screws, and adjusting screws that are inserted into bores of the holder bracket, so as to rotate, and engage into threaded bores of the bracing plate.

A mounting rail bus system for supplying power voltage and data signals to a plurality of modules, including a plurality of longitudinally-arranged bus devices mounting the modules in parallel spaced transverse relation on a mounting rail, each of the bus devices including a printed circuit board having parallel strip conductors for transmitting data signals, and a pair of power contact pins for transmitting a power voltage, characterized by the provision of a plurality of generally L-shaped double bushing contact elements have module bush segments for respectively connecting the strip conductors and the contact pins of the bus device with the associated module, and orthogonally arranged partner bush segments for connecting together the strip conductors and pin contacts of adjacent bus devices, respectively, whereby power voltage and data signals are transmitted from the bus device both to the associated module and to the adjacent partner bus device.

A lifting device is provided. The lifting device includes a top part and a bottom part. A lifting linkage connects the top part to the bottom part and has at least two sub-linkages connected to one another via a central articulation. A drive unit is operable to adjust the height of the top part and act on the central articulation.

The invention is a substitute ventilation radiator belonging to heating and ventilating air condition refrigerating field. The invention includes a radiator, substitute ventilator. The radiator is arranged on the board at one side of the substitute ventilator, the board of the substitute ventilator is used as the bottom board, and the radiator and the substitute ventilator are arranged together back to back. It has characters of substitute ventilation and radiation cooling and heating technology, it can supply fresh wind to room with substitute method, eliminates the humid charge in the room, satisfies the demands of people for fresh air; it can cool or heat the room with radiator, bears the sensible cool or heat charge in the room, upgrades the comfort level and the air quality in room, saves the air condition consumption and the construction space.

A switchable lever for a valve drive of an internal combustion engine which has two side walls with ends connected by a crossbar. There is a gas-exchange valve system in the crossbar at one end and a bearing for the pivotable support of the crossbar at the other end. An axle is held nondisplaceably in the side walls, between the ends, with two cam rollers running on the axle. The cam rollers are displaceable axially on the axle toward each other into a first position such that the cam rollers run up to each other on a longitudinal center plane of the lever and away from each other into a second position. One of the positions serves for a high-lift cam contact and the other position serves for a low-lift or zero-lift cam contact.

An unfavorable geological body crossing tunnel casing bridge underground structure and a construction method thereof belong to the field of tunnel engineering. The unfavorable geological body crossingtunnel casing bridge underground structure comprises a primary lining system, a casing bridge structure and a second lining. The construction method comprises that pipe pieces are embedded onto steeltube arches through grooves, the steel tube arches are connected with first-type support piles through diameter-variable connectors, grade beams are poured on the connecting parts of the first-type support piles, the diameter-variable connectors and the steel tube arch to form the primary lining system; second-type support piles are between the grade beams on both sides of an excavated section, capping beams are poured at the tops of the second-type support piles, a layer of rubber cushion is laid on the capping piles, box girder inverted arches are hoisted onto the rubber cushion to form a casing bridge structure; the primary lining system and the casing bridge structure are connected in a poured mode through the box girder inverted arches and prefabricated reinforcing bars of the gradebeams on both sides; the second lining is poured to form the unfavorable geological body crossing tunnel bridge casing underground structure. The unfavorable geological body crossing tunnel bridge casing underground structure and construction method thereof can cross unfavorable geological bodies such as karst caves, underground rivers and soft ground, and meanwhile, can effectively transfer surrounding rock pressure, reduce deformation of tunnels and ensure construction safety.
