Patent DE-19717331-A1 (DE)
Title: Data transmission driver circuit
Inventor: KUO JAMES R
IPC: H04L25/02
Filed: 1997-04-24
Abstract: The circuit includes a data input node (Vin) and an output transistor (M10) which is coupled between the data output node and ground for the transmission of binary signals from a data system to a transmission conductor. The output transistor has a gate, a source, and a corresponding gate-source voltage between both. A first transistor (M26) is coupled with the gate of the output transistor and reacts to signals which are supplied at the input node. The first transistor conducts a discharge current from the gate of the output transistors to ground the gate of the output transistors and to reduce its gate-source voltage. A clamping circuit limits the gate-source voltage of the output transistors on a first voltage level above ground, to prevent that the discharge current reduces the gate-source voltage of the output transistors to ground potential.

Title: Diagnosis method for IC engine exhaust feedback system
Inventor: NUSSER CLAUS-DIETER
IPC: F02M26/46
Filed: 1997-05-07
Abstract: The diagnosis method is used for an exhaust feedback system in which the approximate fuel quantity for a required mixture ratio is calculated in a control unit using stored data for the exhaust feedback system, with subsequent correction dependent on a regulation factor obtained from the mixture ratio. The regulation factor is obtained with and without the exhaust feedback system being operative, with storage and comparison of the regulation factors and evaluation of the difference between the regulation factors by comparison with given values, for providing a fault signal.
Patent DE-19721595-A1 (DE)
IPC: B22F3/105
Filed: 1997-05-23
Abstract: The invention relates to a method for producing metal functional models and comprises the following steps: a) application of a powder in the form of coatings consisting of several metal constituents on an undersurface, wherein a first constituent has a higher melting point than a second constituent and the second constituent is present in a first phase or a first phase mixture, b) heating of the powder by means of laser radiation, so that the second constituent melts at least partially and wets the first component, c) cooling, so that the powder solidifies. In order to compensate for shrinkage caused by laser sintering, the second constituent is converted into a second phase or a second phase mixture in step lit.c, wherein the specific volume of said second phase or mixture is twice as much as in the first phase or first phase mixture.

Patent DE-19753155-A1 (DE)
Inventor: PAWELLEK FRANZ
IPC: F04B49/02
Filed: 1997-11-29
Abstract: The invention relates to a fuel supply system for an internal combustion engine. The system comprises a high pressure pump which takes in fuel from a low pressure area and supplies it to one of a number of cylinders of the internal combustion engine having a high pressure area. The system also comprises a presupply pump which is driven by an electric motor. The pump feeds fuel under a presupply pressure to the low pressure area. The aim of the invention is to generate a high pressure in the high pressure area as quickly as possible during the starting operation of the internal combustion engine. According to the invention, this is achieved by means of a pressure intensifier with a pressure intensifier piston which has a large active surface and a small active surface. A first pressure chamber which is fluid connected to the low pressure area borders said large active surface, and a second pressure chamber which is fluid connected to the high pressure area borders said small active surface. As a result, a high pressure can be generated in the high pressure area via the pressure intensifier when the presupply pump is already running, however, the high pressure pump however remains idling.

Title: Crossed-coil controller for vehicle speed measurement instrument
Inventor: ITO TADAO
IPC: G01P3/48
Filed: 1998-03-09
