摘要:
A controller for determining whether a previously-detected vehicle wheel speed sensor malfunction still exists. The controller includes an electronic, non-volatile memory, and an electronic processing unit connected to the electronic, non-volatile memory. The electronic processing module includes a malfunction monitoring module, a failure handling module, and a signal checking module. The malfunction monitoring module monitors the operation of at least one wheel speed sensor and generates a fault signal when the at least one sensor malfunctions. The failure handling module causes drive cycle information and the fault information to be stored in the electronic, non-volatile memory. The signal checking module performs a signal check on information from the at least one wheel speed sensor. A tell-tale indicator is deactivated and/or a vehicle control system resumes normal operation if the wheel speed sensor passes the signal check.
摘要:
A mechanism for determining whether a malfunctioning pressure sensor has returned to a normal or acceptable operating range. The mechanism includes controllers and methods that perform a “good check” on the sensor to determine whether the sensor has returned to normal or acceptable operation after a malfunction has been detected. When a previously-malfunctioning sensor passes the “good check,” warning lights (or tell-tale) indicators are shut off and systems that relied upon information from the malfunctioning sensor return to normal operation.

The invention relates to watery resin dispersions, a process for their manufacture, and a product. To make available resin dispersions that do not pollute the environment during their processing, while simultaneously generating products that have a high glass transition temperature, it is suggested that the watery resin dispersion contain at least components (I), (II) and (III), whereby R1: unsubstituted single or polynuclear aromatic rest or with amino groups and/or cyano groups and/or nitrile groups and/or with saturated and/or unsaturated aliphatic C2 to C12 carbon chains substituted single or polynuclear aromatic rests R2, R3 and R4: hydrogen, alkyl residue group with up to 15 C atoms or aromatic rest whereby R2, R3 and R4 can be equal to or different from each other, (II) is a co-dispersion agent based on epoxide resins and/or novolak resins and (II) one surfactant.

A hydraulic system may include a hydraulic actuator. The hydraulic system may also include a pump having a pump inlet and a pump outlet, and the pump may be configured to supply fluid to the hydraulic actuator. The hydraulic system may further include an energy recovery system operatively connected between the hydraulic actuator and the pump. The energy recovery system may be configured to store fluid from the hydraulic actuator under an overrunning load condition, and the stored fluid may be directed through the pump inlet and into the hydraulic actuator.
摘要:
A method for the preparation and processing of epoxy resin molding compositions comprised of epoxy resins, hardeners, fillers and additives, by mixing the epoxy resins with the other components of the composition in a high-speed mixer and granulating the same and homogenizing the resultant free-flowing granules shortly prior to shaping and curing under pressure.

The invention relates to an arrangement enabling a liquid (2) to flow evenly around a surface of a sample (3); said arrangement has a flow chamber (1) through which a liquid (2) flows via inflow and outflow pipes (7, 8). The sample (3) can be rotated about an axis of rotation by means of a rotary drive (5). A filter (13) which extends crosswise to the direction of flow of the liquid (2) and which ensures a uniform flow through the inflow and outflow pipes (7, 8) is situated in front of the inflow and outflow pipes (7, 8). The arrangement is especially suitable for depositing a homogeneous layer of a nickel/iron alloy on a silicon wafer (3). The invention relates furthermore to the use of the arrangement.

The liquid or gaseous substances, such as hydrogen or trichlorosilane, enntered in the gas-phase deposition of silicon may contain n-type doping impurities which can be removed by adduct formation with silicon, titanium or tin halides. The impurities can be liberated from the adducts by thermal treatment and finally removed. The halides left behind are capable of again forming adducts and are again used to remove the impurities. The process can consequently be operated cyclically and is remarkable for the low quantity of chemicals required and for its ecological harmlessness.
