Abstract: An apparatus for segregating and positioning work-pieces and other objects at different desired positions includes a main body, a segregating system, and a plurality of dispensing channels defined in the main body. The segregating system has a receiving chamber and a plurality of gas inlets both defined in the main body. The receiving chamber is configured to house the work-pieces. The gas inlets are configured to allow a high-pressure gas fed therethrough into the receiving chamber. Each dispensing channel has a connecting end communicating with the receiving chamber and a positioning end opposite to the connecting end. The work-pieces are able to be driven by the high-pressure gas to move to the positioning ends through the connecting end.

Abstract: An insulated gate bipolar transistor having a gate electrode (7) and an emitter electrode (9) is provided in a transistor region. A termination region is arranged around the transistor region. A first N type buffer layer (18) is provided below an N type drift layer (1) in the transistor region. A P type collector layer (19) is provided below the first N type buffer layer (18). A second N type buffer layer (20) is provided below the N type drift layer (1) in the termination region. A collector electrode (21) is directly connected to the P type collector layer (19) and the second N type buffer layer (20). An impurity concentration of the second N type buffer layer (20) decreases as a distance from the collector electrode (21) decreases. The second N type buffer layer (20) does not form any ohmic contact with the collector electrode (21).

Abstract: The present invention discloses an underwater building unit and its installation and application methods. It includes a caisson with both ends open and is composed of two rows of box boards being not intersected with each other. Each row of box boards consists of a set of stake-plate body combinations and the bind members between every two adjacent stake-plate body combinations. A positioning beam is located on the top of the box boards and connects the two box boards. There is a cross rib at the middle part of the outer surface of each bind member. The open caisson is made up of small components of low weight. So it is easy for installation and could be extended unlimitedly as required. In addition, the underwater building unit has low underwater condition requirement and is relatively stable, thus the underwater building is quite firm and has a long life. Each component of the open caisson can be industrially manufactured on land so as to lower the cost and free of the influence of stormy waves.
