20110061238 | Method For Forming A Wheel Bearing Apparatus - A method for forming a wheel bearing apparatus where the end portion of the cylindrical portion is pre-formed as a cylinder prior to its plastic deformation to form the caulking portion. A caulking tool with a punch and a swing shaft abuts against the end portion of the cylinder at a predetermined inclined angle relative to the inner circumferential surface of the cylinder. Teeth on the punch form the face-spline by plastically deforming the end face of the caulking portion. The swing shaft central axis is inclined at an angle relative to a central axis of the wheel hub. The face-spline is formed simultaneously with the formation of the caulking portion by advancing the caulking tool toward the wheel hub. A main shaft is rotated to cause a swing motion of the caulking tool. | 03-17-2011 |

20130013842 | CONTROLLER AND TRANSFER SPEED CONTROL METHOD - A USB 3 host controller according to the present invention includes a transfer speed switching unit besides a transfer data converting unit that mutually converts transfer data from a USB device and transfer data from a PCI Express bus. The transfer speed switching unit receives transfer information regarding data transfer from the USB device via a USB 3 interface when the USB device is connected, and identifies a transfer speed used by a PC side according to the transfer information or a result of analyzing the transfer information. Then, when a current transfer speed of the PC side is different from the identified transfer speed, the transfer speed switching unit transmits a speed switching signal indicating switch to the identified transfer speed to a PCI master via a PCI express interface. | 01-10-2013 |

20090001810 | Power Unit of Underwater Vehicle - The present invention provides a power unit of an underwater vehicle, which allows reduction in size and weight of a transformer for stepping down a power voltage of a power supply to increase a loading amount of a variety of devices with respect to the underwater vehicle, so as to obtain a favorable operating environment. The power unit is connected to the power supply through a cable and receives power through the cable. Further, the power unit comprises an electronic transformer having: a rectifier for rectifying a high-voltage alternate current power of the power supply into a direct current; a high-frequency converter for converting an output of the rectifier into a high-frequency alternate current; a transformer for stepping down an output voltage of the high-frequency converter; a rectifier for rectifying an output of the transformer into a direct current; and a control circuit for controlling the high-frequency converter. | 01-01-2009 |

20120277381 | HYBRID-TYPE POLYESTER RESIN, RESIN COMPOSITION FOR FORMATION OF FILM, AND POLYESTER FILM AND TEXTILE - Provided is a hybrid-type polyester resin which, when used in processing a base material such as textile or PET film, can impart excellent flame retardance to the base material. The hybrid-type polyester resin can be inhibited from scattering high-temperature drips, even if the hybrid-type polyester resin burns. The hybrid-type polyester resin comprises both a polyester resin and a siloxane prepared from silica and an alkoxysilane. Therefore, the hybrid-type polyester resin retains the excellent properties inherent in polyester resin and exhibits extremely excellent flame retardance by virtue of hybridization with the siloxane. Even if the hybrid-type polyester resin burns, the hybrid-type polyester resin is less susceptible to deformation, and is therefore inhibited from scattering high-temperature drips. | 11-01-2012 |
