Abstract: A converter including a semiconductor module and a cooling housing. The semiconductor module includes a semiconductor chip, a substrate having a first side and a second side, a base plate having a first side and a second side, and a molding compound. The semiconductor chip connects to the first side of the substrate. The second side of the substrate connects to the first side of the base plate, the second side of the base plate has a first region and a second region. The first region has a surface expansion, and the first region having the surface expansion contacts with a coolant liquid in an operating state. The second region forms a closed path around the first region, the cooling housing has a plate including at least one hole, and the plate is connected around the hole to the second region of the base plate by welding.

Abstract: A converter for transferring power from a medium-voltage, MV, to a low-voltage, LV, side is provided. The converter includes at least one DC/AC cell with a MV AC terminal configured for generating an AC voltage from a MV DC voltage, and includes at least one AC/DC cell with a LV AC terminal configured for generating a DC voltage from a LV AC voltage. The converter has a magnetic core with a LV winding, and a LV terminal connected to the LV AC terminal, additionally with a magnetic core with a MV winding, and a MV terminal connected to the MV AC terminal. The converter includes an auxiliary unit with an auxiliary winding, and an auxiliary terminal connected to control circuits for operating the MV DC/AC cell. Galvanic insulation between the LV and the MV winding and the auxiliary winding is configured to withstand the Basic Insulation Level of the converter.

Abstract: A vehicle service tag sheet system for facilitating a vehicle service request generally includes a pad of sheets attached to a backing material of a thickness sufficient to allow a service station attendant to take notes on one of the sheets without placing the pad on a hard surface. In one embodiment, each sheet includes a vehicle identification section that has printed thereon an identification number, and a key identification section that has printed thereon the identification number. Each sheet also includes a services section that has printed thereon the identification number and prompts for reminding the user to take down pertinent information for the vehicle service request.

Abstract: A thermostat for use within a building consisting of a wall-mounted unit and a remote unit movably attached thereto by means of a removable, flexible connecting cable. The remote unit is composed of a separate base portion and a separate movable portion. The base portion is provided with means for attaching the base portion to the back of a room furnishing and the movable portion can removably attach to either the wall-mounted unit when the connecting cable is removed or to the base portion when the connecting cable is reattached. The base portion is provided with "U" shaped sides which form a track for movably receiving the movable portion when the movable portion is disengaged from the wall-mounted unit.
