A method of configuring a hard disk drive with a transparent cover allows the elements of the disk drive to be observed while they are in operation. The cover also can be tinted with different colors or made somewhat translucent for further differentiation. In addition, decorations and/or various patterns, such as a diffraction grating pattern, may be placed or formed on the cover, the hub, and/or the actuator to further emphasize particular aspects of the disk drive. A flashing device can also be used to accentuate the rotational motion of the disk and/or hub.

A device for determining set values for the braking forces or braking torque of the brake system of a vehicle comprising an electric drive, a friction brake applying braking forces to all wheels according to corresponding set values, an electrodynamic regenerative brake applying braking forces to at least one axle according to corresponding set values, and an element for determining the set values according to the desired vehicle deceleration, wherein such element for determining the set values according to the deceleration requirement either makes the set value for the electric regenerative as large as possible or sets the set values for the electrodynamic regenerative brake and for the friction brake primarily according to criteria concerning the distribution of the braking forces on the axles. In addition, an element for correcting a set value for the friction brake, preferably at the front axle according to the dynamic behavior of the electrodynamic regenerative brake may be provided.

A brake power booster is equipped with a device for determining an input force introduced at a brake pedal. According to the present invention, the device which uses a pressure generator for measuring the input force is interposed between the end of an actuating rod, connected to the brake pedal, and a valve piston that actuates a control valve of the brake power booster. The pressure generator is exposed to the effect of a pressure which develops in a pressure chamber and is built up in an elastic substance or an elastomer.

A method for calculation of the lateral force in a motor vehicle with an electromechanical or electrohydraulic steering system is disclosed. The method comprises the following steps: firstly a steering column force is recorded, from which a total restoring torque is calculated. The total restoring torque comprises restoring torques generated by differing forces acting on the wheels. Said restoring torques include a restoring torque generated by lateral force and other restoring torques. The other restoring torques are quantitatively determined on the basis of measured values and subtracted from the total restoring torque, in order to determine the restoring torque generated by lateral force. Finally the lateral force is determined from the restoring torque generated by the lateral force.

The invention proposes a process for determining the driving torque of a vehicle as it is starting. This process and device uses a model of the idling properties of the engine, a comparing element for the output values of the model and corresponding measured values or values derived therefrom, and a determining element for determining the driving torque of the vehicle according to the results of the comparison. Furthermore, the invention discloses a process and device for determining an externally generated variable that drives or brakes the vehicle as well as for supporting uphill starting. In addition, processes and devices for determining externally generated variables/torques as well as for supporting uphill starting are disclosed.

A method for introducing at least one gaseous reducing agent for a nitrogen oxide into a gas mixture, and a device for carrying out the method. Thermal energy is supplied to a body made from a starting material of the reducing agent, so as to form the reducing agent. The starting material used is urea. The reducing agent formed is ammonia. This method is used in particular to reduce nitrogen oxides in the exhaust gas from internal-combustion engines.

A multi-shelled melt container is disclosed for liquefying and crystallizing substances which comprises at least an inner shell and a bearing shell. While the inner shell--which has a thin wall in comparison to the wall of the bearing shell--consists of an inert material with respect to the melt, the bearing shell serves exclusively to fixate and support the inner shell and is correspondingly constructed in a mechanically stable fashion. The device can also comprise means to pump the melt over into a collection vessel.

A brake unit for motor vehicles with electric drive with a hydraulic pressure transducer and hydraulic friction brakes to increase the brake effect applied by the electric drive motor. The cooperation of the electric drive motor with the hydraulic friction brakes is controlled by an electronic controller. To increase the reliability of operation of the brake unit by making possible the buildup of hydraulic pressure in the friction brakes associated with the driven axle in the case of a failure of the electronic controller or of the entire electric system of the vehicle, the pressure transducer is arranged as a two-circuit main brake cylinder, to the first pressure space of which the friction brakes acting on the nondriven axle, and to the second pressure space of which the friction brakes acting on the driven axle are connected, wherein the connection between the second pressure space and the friction brakes acting on the driven axle is by at least one shut-off valve, which can be switched over electrically and is open in the currentless state.
摘要:
A doped starting substance is applied to a substrate composed of SiO.sub.2 glass. A phosphor layer is formed by reaction of the starting substance with SiO.sub.2 of the substrate to form a silicate of the starting substance. This reaction is carried out in a heat-treatment process in an oxygen-containing atmosphere. Zn or Gd is preferably used as starting substance.
