摘要:
The invention relates to a method for the selective silicidation of contact areas that allow the production of highly integrated circuits, preferably in a SMOS or BiCMOS process. To this end, a metal oxide layer (14) that contains for example praseodymium oxide is deposited onto a prepared wafer (12). A silicon layer (16) and on top of said silicon layer a cover layer (18) is deposited onto the metal oxide layer (14), said cover layer being laterally structured. In a subsequent tempering step in an oxygen-free, reducing gas atmosphere the silicon layer (16) and the metal oxide layer (14) are converted to a metal silicide layer in lateral sections (20, 22) in which the cover layer (18) was previously removed.

A passenger sensor for a passenger conveyor is disposed adjacent to a floorplate and produces a signal in response to changes in the load on the floorplate, rather than in response to a predetermined level of load. This results in a passenger sensor that does not require adjustment to accommodate the changing conditions of the passenger conveyor. In a particular embodiment, the passenger conveyor includes a passenger sensor that is formed from a piezoelectric cable that extends about the perimeter of the floorplate. The piezoelectric cable is connected to a controller that determines the operational speed of the passenger conveyor. Changes in the load on the floorplate, such as caused by a passenger entering the passenger conveyor, result in the piezoelectric cable generating a signal that is received by the controller. The controller then adjusts the operation speed of the passenger conveyor in response to the signal.

An information display and control device for a passenger conveyor includes a housing and a post. The device is separate from the passenger conveyor and is positioned at a desirable location that is viewable by passengers approaching the passenger conveyor. The housing is mounted on the post at a predetermined height to avoid inadvertent tampering with the components of the housing. In one particular embodiment, the components of the housing include a traffic light, a control panel and an emergency switch.

A control system for a passenger conveyor includes a plurality of junction boxes distributed throughout the conveyor and a control unit. The control unit communicates with the plurality of junction boxes through a serial link that interconnects the junction boxes and control unit. In a particular embodiment, the control unit is located remotely from the truss of the conveyor.

A passenger sensor for a conveyor includes a transmitter assembly that is positioned within a channel in the conveyor balustrade. The transmitter assembly includes a plurality of transmitters that are spaced along a cable to form a transmitter chain. Each transmitter includes a module and a connector attached thereto. The transmitter assembly is disposed within the channel without the need for mounting hardware or openings within the balustrade for the passage of the cable. In a particular embodiment, a receiver assembly is disposed in a channel in the opposite balustrade in a similar manner.

An internal-combustion engine comprising an intake system has a chamber with an intake connection and individual suction pipes which are connected with a cylinder head and which, by means of valves, lead into the individual cylinders. An air supply and air purification system is connected with the intake connection. An air guiding pipe is connected with the intake connection of the chamber, which air guiding pipe projects freely into the chamber and is arranged coaxially with respect to it. The mouth opening of the air guiding pipe extends in a plane at a right angle with respect to the lateral wall of the chamber and has an identical distance to the center axes of the individual suction pipes of a second and third cylinder of the internal-combustion engine.

An internal-combustion engine having an intake system comprises a chamber having an intake connection and individual suction pipes which are connected with a cylinder head and which lead into the individual cylinders. The interior of the chamber is connected to a pollutant reducing system which comprises at least one of the systems, such as a housing venting system, an auxiliary-air feeding system, a fuel vapor catch system and an exhaust gas return system. An intake pipe, which projects into the chamber of the intake system, which has a mouth opening approximately in a plane between two central individual suction pipes, is fastened to the intake connection, and a pipe connection, which connects the systems of the pollutant reducing system, leads into the interior of the chamber.
摘要:
An intake system for an internal-combustion engine, having a suction manifold comprising a chamber, has an intake connection on the inflow side and several individual suction pipes on the outflow side, which suction pipes lead into a cylinder head of the internal-combustion engine and are connected with the individual cylinders. The intake connection has an air guiding device which extends approximately to a plane extending between the two center suction pipes, and a wall of the air guiding device directed toward the interior openings of the suction pipes is arranged at a distance from these openings.
