20130167731 | ATTACHMENT FOR A TEA KETTLE - An attachment for a container for the preparation of an extraction beverage comprises a base plate mounted horizontally on the container, having an aperture for an extraction product container to pass through, and a lifting apparatus which comprises a sleeve. The lifting apparatus has a guide fixed to the base plate for guiding the sleeve in a direction perpendicular to the base plate. The lower position defines a brewing position of the sleeve and the upper position defines an inoperative position. A locking apparatus locks the sleeve in the brewing position. A timer is also provided for operating the locking apparatus so that after a predefinable time period the sleeve is unlocked when it is locked in the brewing position. The sleeve is acted on by a restoring force to move from the brewing position to the inoperative position when the sleeve is unlocked. | 07-04-2013 |

20100019018 | Method And Device For Wetting The Bumps Of A Semiconductor Chip With Soldering Flux - The present invention relates to a method and a device for wetting the bumps of a semiconductor chip with a soldering flux, in which a container, which accommodates the soldering flux and is open on the bottom, and a base plate, which contains at least one cavity, are moved back-and-forth in relation to one another on one side of the cavity to the other side of the cavity. The viewed in the movement direction front wall of the container is lifted up during the relative movement, so that it is located at a distance above the base plate. The distance is somewhat greater than the height difference by which the soldering flux projects above the level of the surface of the base plate. This measure has the effect that the front wall of the container does not convey any soldering flux onto the base plate, which has caused the loss of this soldering flux until now. | 01-28-2010 |
20100040449 | Apparatus For Mounting A Flip Chip On A Substrate - The invention relates to an apparatus for mounting semiconductor chips as flip chip on a substrate. The apparatus comprises means for supplying the semiconductor chips, a pick-and-place system with a bonding head with a chip gripper, a flipping apparatus with a gripper and two cameras. The first camera is used for determining the actual position of the semiconductor chip that is provided by the said means for mounting before the flipping apparatus receives the semiconductor chip, and it is used to determine the actual position of the flip chip received by the chip gripper of the bonding head once the flipping apparatus has transferred the semiconductor chip. The apparatus comprises an optical switch in accordance with the invention, e.g., a rotatably held mirror which is located in the field of view of the first camera. In operation, the mirror is rotated simultaneously with the gripper of the flipping apparatus, but only by half the angle. | 02-18-2010 |
20130133188 | Apparatus For Mounting Semiconductor Chips - An apparatus includes a pick and place system with a bonding head, picking head and support table. The picking head and support table are mounted on a carriage. The apparatus can be operated in a direct mode and a parallel mode. In the direct mode the carriage is in a first position (parked). A control unit operates the pick and place system to cause the bonding head to move a series of semiconductor chips from the wafer table to the substrate. In the parallel mode, the carriage is in a second position. The control unit operates the picking head, support table and pick and place system to repeatedly cause the picking head to move a semiconductor chip from the wafer table to the support table and the bonding head to move said semiconductor chip from the support table to the substrate. | 05-30-2013 |
20140305372 | Device For Dispensing Adhesive On A Substrate - A device for dispensing adhesive on a substrate comprises a writing head with a first dispensing nozzle and at least one second dispensing nozzle. The device can be operated in two operating modes and is configured to perform the following steps for the change from the one operating mode to the other operating mode: | 10-16-2014 |

20090086313 | STEREOMICROSCOPE - A stereomicroscope of the telescope type includes a first beam path and a second beam path, wherein in the first beam path a first telescope system and in the second beam path a second telescope system are provided, wherein the magnifications of both telescope systems are equal and can be changed synchronously to each other, and wherein a common main objective is allocated to both beam paths. In order to increase the resolution without loss in depth of field, it is proposed that at least one optical element of the first telescope system has, compared to at least one corresponding optical element of the second telescope system, a different optically effective diameter. | 04-02-2009 |
20120120223 | PORTABLE MICROSCOPE - A portable microscope includes an integrated operator control unit configured for at least one of selecting and adjusting at least one electrically controllable function of the microscope. The operator control unit includes at least one sensor configured to receive user control commands for at least one of activation, deactivation and adjustment of the at least one electrically controllable function. The at least one sensor includes a touch sensor and is disposed so as to accommodate holding and operation of the microscope with a single hand of a user. | 05-17-2012 |
20120120224 | MICROSCOPE HAVING A TOUCH SCREEN - A microscope includes an image acquisition system, microscope components and a touch screen. The image acquisition system is configured to optically and digitally image an object so as to produce an object image The microscope components are at least one of motorized and electrically controllable. The touch screen is configured to display the object image in a display area thereof and to sense inputs in the display area within the displayed object image so as to change settings of the microscope components. | 05-17-2012 |

20110213586 | Device and Method for Transmitting Data Between a Position-Measuring Device and Sequential Electronics - In a device and a method for transmitting data between a position-measuring device and sequential electronics via a data-transmission channel, the position-measuring device includes an interface unit and a processing unit, the interface unit being connected first of all to the data-transmission channel, and secondly, to the processing unit for the purpose of an internal data exchange with the aid of a request channel and a response channel. The interface unit includes a command interpreter by which, using conversion rules, commands which arrive via the data-transmission channel are convertible into internal requests and are able to be fed via the request channel to the processing unit, and response data which arrives from the processing unit via the response channel is convertible into output data. The interface unit further includes a rules memory for storing the conversion rules, which is at least partially modifiable. | 09-01-2011 |
