The invention relates to a classifier for automatically testing wafers, which comprises a feeding box, a receiving box and an empty box arranged at the front end of a stand. The feeding box is used for placing wafers to be tested, the receiving box is used for placing the tested wafers with different levels, while the empty box can receive an empty charging tray at the feeding box or an empty charging tray needing to supplement the receiving box. In addition, a test device is arranged at the back end of the stand, and is provided with a tester and a probe capable of lifting; two transfer devices capable of moving between a transportation area and the test device transfer the wafers to be tested alternately to the test device to test, and transfer the wafers after being tested to the transportation area; and a pick-and-place device is used for picking the wafers to be tested on the feeding box and placing the wafers on the two transfer devices, and picking and placing the tested wafers on the two transfer devices to the receiving boxes with different levels respectively according to the test result. Therefore, the classifier can ensure quality of the tested articles and effectively promote working convenience and usage benefit of productivity.

The present invention relates to a mobile meat roaster, which includes: a casing which forms the outer body; a heat supply part mounted in the casing for providing heat to food; and a first grill operation part mounted at an upper portion of the heat supply part for rotating the grill as well as moving it in the vertical and horizontal directions, wherein the first grill operation part includes a grill fixing part for attaching or detaching an end of the grill, a horizontal moving means for moving the grill in the horizontal direction, a rotation means for rotating the grill, and a lifting means for moving the grill in the vertical direction, and, accordingly, the cooking status of the grilled food may be accurately assessed by moving the grill forward, a user is protected from gas inhalation and burns from flames, and overall convenience is improved.; Furthermore, as the grill rotates, heat is evenly distributed over the grilled food, burnt areas are avoided and taste is improved. Temperature may be kept uniform so that the food may be uniformly cooked without local burning or undercooking, since the grill rotates continuously. Additionally, the grilled food tastes better since it is dependant on the cook's manual efforts in turning the roasting food. Accordingly, uniform taste may be achieved regardless of the personal skills of a cook and seasoning becomes convenient for the cook.

The invention relates to a probe that is comprised in an ultrasonic diagnostic system, wherein the probe comprises: a scanhead which includes a housing that functions as a handle, a transducer that is installed on one side of the housing, a tuning board that is accommodated within the housing and has one side connected with a PCB of the transducer, and a board connection-connector that is connected with the other side of the tuning board; and a cable assembly which has one end on which a scanhead connector detachably coupled with the board-connection connector is positioned, and has the other end on which a system connector is placed. Since the scanhead can be separated from the cable assembly such that the scanhead can be replaced, overall convenience of a user is improved greatly, and consequently, the ultrasonic diagnostic system can be miniaturized and carried in a portable form.

A fuel cell has a unit cell in which a membrane electrode assembly, in which a pair of electrodes are provided on either side of an electrolyte membrane, is provided between a first separator and a second separator. Pin insertion holes are respectively provided in a plurality of portions in an outer periphery of each of the first and the second separators, and the pin insertion holes of the first separators are respectively coaxial with those of the second separator. A leg portion of a cell fastening pin made of resin is inserted through each pair of the coaxial pin insertion holes of the first and the second separators. The unit cell is fastened by fitting a flange portion formed at an end of the leg portion to the first separator, and fitting a hook portion formed at the other end of the leg portion to the second separator.

The invention discloses a wireless projection type auto-changing shade welding mask. The welding mask comprises a mask shell, a headband structure used for fixing the mask shell, an auto-changing shade filter fixed to the mask shell, a wireless communication module, and a micro projector in data connection with the auto-changing shade filter and the wireless communication module, wherein the micro projector can project operation parameters of the auto-changing shade filter and / or data received by the wireless communication module onto the plane in front of the welding mask when the auto-changing shade filter is in the transparent state, so as to enable observation of a wearer of the welding mask. The invention further discloses a welding device provided with the wireless projection type auto-changing shade welding mask.
