  • Patent number: 8020422
    Abstract: A tubular product comprises a side section having outer surfaces disposed along a parallelogram and a bottom section formed on one end of the side section. The outer surfaces of the side section are pressure formed by a roller. The tubular product preferably is manufactured from a tubular material by a process comprising the use of a device having a roller that is configured to engage with a side section of the tubular material. The device also comprises a mandrel configured to position the tubular material so that the roller can apply pressure against at least a portion of the outer surfaces of the side section and can extend the side section of the tubular material to form the product.

  • Publication number: 20100198459
    Abstract: Application data generated by an ECU is wireless transmitted by a transmission device in a subject vehicle so as to periodically change a communications distance by changing, every transmission timing, at least one of (i) a transmission rate, which is used in transforming a transmission packet into a transmission signal in a modulation section, and (ii) a transmission power, which is configured by an amplification section to amplify the transmission signal. As a result, the data transmission from the subject vehicle can be made (i) in high repetition times with respect to a nearby vehicle having a greater risk of collision (i.e., time to collision being shorter), and (ii) in low repetition times with respect to a distant vehicle having a less risk of collision (i.e., time to collision being longer).

  • Patent number: 7708621
    Abstract: This polishing apparatus includes a head that holds a semiconductor wafer, a polishing pad that polishes a surface to be polished of the semiconductor wafer held by the head, and a dresser that reconditions the polishing pad by cutting the polishing pad. The polishing apparatus polishes a surface to be polished of the semiconductor wafer while causing the head and the polishing pad to rotate and reconditions the polishing pad by use of the dresser before and after polishing the surface to be polished. The polishing apparatus of the present invention supports at least two dressers so that the dressers can rotate on their own axes and further includes a dresser oscillator that causes the dressers to oscillate simultaneously on the polishing pad.

  • Patent number: 7559827
    Abstract: A dresser adapted to a chemical mechanical polishing apparatus is used to perform dressing on a polishing pad for polishing a semiconductor wafer such that a circular-shaped support surface thereof is positioned opposite to and in contact with the polishing surface of the polishing pad. In the dresser, at least three polish retainers having band-like shapes are formed and elongated in radial directions from substantially the center of the support surface so as to form a plurality of sectorial regions. A plurality of parallel portions are formed in parallel with the polish retainer in each sectorial region. A plurality of band-shaped non-polish retainers are formed between the polish retainer and its parallel portion in each sectorial region. The dresser ensures adequate fuzziness of the polishing pad by way of dressing; hence, it is possible to maintain desired polishing performance of the polishing pad for a long time.
