One or more feedback elements generate a feedback signal in response to a transmitted signal outputted by each radiator of the antenna system. This feedback signal is received by each radiator, also described as a radiating element, and combined with any leakage signal present at the port of the antenna. Because the feedback signal and the leakage signal are set to the same frequency and are approximately 180 degrees out of phase, this signal summing operation serves to cancel both signals at the output port, thereby improving the port-to-port isolation characteristic of the antenna. Each feedback element can include a photo-etched planar metal strip supported by a planar dielectric card made from printed circuit board material. Such feedback elements can provide a high degree of repeatability and reliability in that the manufacturing of such feedback elements can be precisely controlled.

The invention provides a precision die forging and shaping technical method for automobile steering knuckle rough type parts. The precision die forging and shaping technical method mainly comprises the process steps of blanking, heating, extruding and drawing out a rod part, pre-forging, upsetting, performing material distribution and performing multi-way precision die forging and shaping and is specifically as follows: blanking through a cutting device, and heating to the temperature of 1080 DEG C-1180 DEG C in a medium-frequency induction furnace; placing a round bar which is well heated into a female die of an extruding and drawing-out die to form a stock comprising a cylindrical surface and a steering knuckle rough rod part; placing the stock after upsetting and material distribution into a multi-way die forging die, firstly enabling an upper male die and an upper die seat in the vertical direction to move downwards, and closing the upper male die and a lower female die for forging; and then using male dies on the symmetrical left side and right side in the horizontal direction to perform extrusion precision forging and shaping. According to the method provided by the invention, as the die forging is performed on a multi-way die forging hydraulic machine, the shaping speed is much lower than that of die forging on a hammer, thus the occurrence of the phenomenon of forming cracks on the surface due to strong speed sensitivity caused by too-high speed can be avoided; and the contact friction resistance between a forged piece and the surface of a die cavity during the processes of die forging, shaping and ejection of the forced piece can be greatly reduced, the surface quality of the forged piece is further improved, and the utilization rate of the material of the forged piece is improved.

A turbocharger including a turbine wheel having a hub-to-tip ratio of no more than 60% and blades with a high turning angle, a turbine housing forming an inwardly spiraling primary-scroll passageway that significantly converges to produce highly accelerated airflow into the turbine at high circumferential angles, and a two-sided parallel compressor. The compressor and turbine each produce substantially no axial force, allowing the use of minimal axial thrust bearings.

The invention relates to a drive circuit for an injector arrangement comprising a first fuel injector in parallel with a capacitive component. The drive circuit comprises: a selector means (SQ1, SQ2) and diagnostic means. The selector means (SQ1, SQ2) is operable to select the first fuel injector and / or the capacitive component into the drive circuit and to deselect the first fuel injector and / or the capacitive component from the drive circuit. When the capacitive component is selected and the first fuel injector is deselected, the diagnostic means is operable to sense a current (Isense) through the first fuel injector. When the sensed current (Isense) is at variance from a first threshold current (Ilimit) the diagnostic means is operable to provide a first signal on detection of a stack terminal short circuit fault associated with the first fuel injector. The capacitive component may be a second fuel injector.
