Abstract: An HOD device, comprising: a framework; covering material, covering the frame work; at least one conductive region, provided on or in the covering material; wherein the conductive region is coupled to a capacitance detection circuit or a predetermined voltage level. The HOD device can be a vehicle control device such as a steering wheel. The conductive region comprises conductive wires which can be threads of the covering material. By this way, the arrangements of the conductive wires can be changed corresponding to the size or the shape of the frame work or any other requirements. Also, the interference caused by unstable factors can be improved since the conductive wires can be coupled to a ground source of the vehicle to provide a short capacitance sensing path.

Abstract: The invention is directed to a method for manufacturing a field plate of a high voltage device. The field plate is located on a drift region of a substrate, wherein an isolation structure is located on the drift region. The method comprises steps of forming a first dielectric layer over the substrate and then forming a first patterned conductive layer on the first dielectric layer, wherein the first patterned conductive layer is located over the isolation structure and exposes a portion of a top surface of the first dielectric layer. The exposed portion of the first dielectric layer is removed until a top surface of the isolation structure so as to form a plurality of vertical fin-type dielectric bottoms.

Abstract: An axial flow control valve comprises a valve body having a flow passage containing therein a cylinder and an annular sleeve both are held in position by a positioning sleeve. The annular sleeve has a wall member formed with a multi-pores means for providing a number of V-shaped or elongate ports for reducing noise and vibration of fluid flow. A push rod is axially movably disposed within the cylinder, having one end attached with a resiliently biasing means for resiliently engaging a valve piston axially displaceable within the cylinder and the annular sleeve for controlling fluid flow. The positioning sleeve is formed with a truncated conical valve seat to associate with the valve piston for sealingly occluding fluid flow. O-rings made of resiliently metallic or ceramic material are disposed on the valve piston and/or the push rod for sealing the axially movable elements, so that the valve can be used in a high-temperature environment.
