Abstract: A bearing bush for supporting a motor vehicle part includes an inner tube made of a metal, a sliding sleeve made of a first plastic material and mounted rotatably on the inner tube, and an elastomer bearing which surrounds the sliding sleeve and has at least a first elastomer body and an outer sleeve. A sliding layer made of a second plastic material is applied to an outer circumferential surface of the inner tube, the first plastic material and the second plastic material forming a tribological pairing either of two different polymers from the groups of polyamides, polyoxymethylenes, polyketones, fluoropolymers, polyethylene terephthalates or polybutylene terephthalates, or the tribological pairing being formed from polyketone against polyketone, wherein the polymers of the tribological pairings each are present in a continuous thermoplastic polymer phase.

Abstract: A method for dielectrically insulating active electric parts A method for dielectrically insulating an active electric part wherein the electrical active part is arranged in a gas-tight housing comprising an insulating gas which contains or consists of a compound of formula (i) Rf1-(O)x-Rf2 wherein Rf1 and Rf2 are identical or different and designated fluorocarbon residues having a H/F ratio of equal to or less than 0.5 and x is 1, 2, or 3.

Abstract: A pressure switch including: a spring blade; a ram pin having an angled bottom surface and laterally restrained in movement, where upward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an engaged position, and where downward movement of the ram pin engages the spring blade such that the spring blade snap deflects to an unengaged position; a ball bearing in contact with the angled bottom surface of the ram pin; and an adjustment screw laterally restraining the ball bearing in movement, where a lateral inward movement of the adjustment screw relative to an outside surface of the pressure switch causes an upward movement of the ram pin, and where a lateral outward movement of the adjustment screw relative to the outside surface of the pressure switch causes a downward movement of the ram pin.

Abstract: An electrical apparatus for a medium- to high-voltage current transport line having a gas insulation including: a sealed housing filled with an electrically insulating gas including at least one fluorinated compound such as a fluoroketone, at least one electrical component arranged inside the inner space of the housing, and a mechanism regulating an amount of the fluorinated compound inside the inner space of the housing. The regulating mechanism includes a heater, heating a liquid resulting from condensation of the fluorinated product present in the insulating gas, to cause at least a portion of the liquid to vaporize.

Abstract: The present invention provides, at a lower cost, a highly reliable data reading method and data reading apparatus that can improve backward sequential reading performance. The disk drive is provided with a magnetic disk and a control section having an HDC, a RAM, an MPU controlling the operation of the entire HDD, including control of the HDC, a ROM, and an I/F for connecting to an external host device. The control section executes a backward reading detection step that detects backward reading, a step of receiving a command that reads a block of a first length from a first LBA, a step that reads a block of the first length from the first LBA when backward reading is detected, and a step that pre-fetches a second block from a second LBA smaller than the first LBA; when backward reading is detected, upon completion of the reading of data from the disk, the reading of data predicted to be requested by the next command begins immediately.
