When an upper arm of U-phase has failed because of short-circuit, lower arms of V-phase phase and W-phase as the opposite arms are switching-operated. When only the lower arm of V-phase is turned on, a route of motor current passing through an IGBT element from a V-phase coil is formed, and therefore, the motor current returning to the short-circuited phase decreases. Further, by the switching operation of the arm opposite to the short-circuited arm, an AC current is induced in a motor generator. Therefore, it is possible to continuously drive the motor generator while preventing increase in the current passing through the short-circuited phase, without adding a new device structure. This ensures running of the vehicle in the limp mode.

The invention provides a device for accurately locating ends of cords, wires cables or conduits, in particular in the fields of electricity, electronics, telephone and computer. The device includes an optical fiber disposed on a cord and extending from a first end to a second end of the cord. The optical fiber includes a first fiber end disposed at the first end of the cord and a second fiber end disposed at the second end of the cord. The device further includes a means for injecting light disposed proximate the first fiber end, the first fiber end being accessible so as to be illuminated by the means for injecting light and the second fiber end being accessible so as to recover the light injected at the first fiber end. Said device is useful for locating computer switching cords.

In a method for repairing and/or upgrading a component (10′), preferably of a gas turbine, especially a blade (10′), which component has been deformed during operation, a simplification with cost advantages is achieved by a first nominal CAD model (M1) of the non-deformed component (10) being made available, by the deformed component (10′) being measured, and by the first CAD-model (M1), with the aid of the data determined on the deformed component (10′), being transformed into a second CAD model (M2) of the deformed component (10′) by morphing. A cutting line, which determines a cut-out in the component (10′), and also an insert piece, which can be inserted in the cut-out, is established in the second CAD model (M2). A cut-out is introduced into the component (10′) in accordance with the cutting line, an insert piece for inserting in the cut-out is manufactured in accordance with the cutting line, the manufactured insert piece is inserted in the cut-out, and the inserted insert piece is connected to the component (10′) in a materially bonding manner.

A pump, in particular a centrifugal pump, includes at least one flow-leading part with an at least regional surface layer (50) of an elastomer. The flow-leading part with the surface layer (50) is formed as a multi-component injection moulded part, with a base structure (55) made of plastic as a first component, and with the elastomer as a second component.

A volatile liquid droplet dispenser device includes: a first substrate (1) having a space (2c) for containing a liquid substance, and having liquid outlet means (2a) for ejecting the liquid substance; a second substrate (3) having a liquid inlet means (3i) for allowing the liquid substance to enter said device; an actuating element (2b, 8, 10) arranged to actuate the liquid substance so as to exit the device as a liquid droplet spray, wherein the liquid outlet means (2a) of the first substrate comprises a perforated nozzle membrane (2a) having a plurality of outlet nozzles, and wherein the first substrate (1) contains at least one fluidic capillary priming channel (1a, 1b, 1c) arranged to receive liquid substance from the space (2c) so as to fill the channel such that the liquid substance is in close proximity to the outlet nozzles for priming the liquid substance for ejection through the nozzle membrane.

A system for extracting oil from oil-bearing plant parts has an extraction vessel supported by an upright stand, a separator vessel mounted below the extraction vessel, and an expansion filter vessel mounted downstream from the separator vessel. A source of hydrocarbon solvent supplies liquid gas to the top of the extraction vessel, while a recycling pump connected to the separator vessel facilitates transport of the solvent through the plant material in the extraction vessel. The solvent is recovered and re-circulated, while extracted oil is removed from the separator. A computer-based temperature control assembly having a cooling device and a jacketed injection coil regulates temperature of the solvent delivered to the extraction assembly. A thermal jacket is mounted on each of the separator vessel and the expansion filter vessel, with the thermal jackets supplying heat and cold to the interior of the separator vessel and the expansion filter vessel and helping evaporate and condense the solvent.

A method for operating an internal combustion engine, in which an erroneous lift of an intake valve of a cylinder is directly determined. The lift of an intake valve of at least one cylinder of the internal combustion engine is diagnosed. A value for a specific cylinder which is representative of the air/fuel ratio in the respective cylinder is determined in an exhaust system branch of the internal combustion engine. At least one such value is compared to a predefined value. An erroneous lift of the intake valve is diagnosed as a function of the deviation of this at least one value from the predefined value.

The invention relates to an endoscope head which is equipped with a plurality of function-related units such as an optical/lens system, illuminating elements, rinsing nozzles and the like. The endoscope head substantially comprises a plurality of modular plug-in or click-in function-related supports for receiving and/or forming the function-related units.

A Stutzen stock of a repeating rifle that includes a stock front portion and a stock rear portion. To make available a more versatile Stutzen stock, the stock front portion is detachably connected to the stock rear portion.

A solenoid valve assembly of a variable damping force damper and a method of assembling the same are disclosed. The method includes coupling a valve housing to one side of a damper, accommodating an embedded assembly within the valve housing, the embedded assembly including a variable fluid path component and a solenoid operator, disposing a bobbin housing such that an inner circumference of the bobbin housing partially overlaps an outer circumference of the valve housing, while adjusting orientation of a power line connected to a bobbin accommodated in the bobbin housing, and fastening the bobbin housing to the valve housing, with the orientation of the power line adjusted.
