20090115220Vehicle Door Frame and Method for Making Same - A vehicle door frame includes a first frame 05-07-2009
20090295194Door frame for vehicle - A first fitting portion of a vehicle door frame is formed to enable attachment of a bending-type door weather strip including a lip thereto. A second fitting portion is formed to enable attachment of a parting weather strip thereto. A first seal surface is formed to enable the lip to be pressed thereagainst. A second seal surface is formed to enable attachment of an opening weather strip thereto, which is attached to a vehicle body inward relative to the vehicle from the door weather strip. The second fitting portion includes a bottom wall portion and an engagement piece that is folded back from the bottom wall portion at one side end of the bottom wall portion. The parting weather strip is engageable with the engagement piece. The first fitting portion includes the side end and a wall that is arranged at a rear side of the bottom wall portion. The wall is formed so that the side end projects toward the wall. Accordingly, the number of processing steps when rolling the door frame rolling process is prevented from increasing, and the door frame obtains a high sealing capacity and ornamentality.12-03-2009
20100181798JOINT STRUCTURE OF DOOR EDGE MEMBER - A joint structure of a door edge member includes a door upper edge member having a baglike cross section, constituted by inner surfaces, at the longitudinal end portion thereof, and a door rear edge member having the longitudinal end portion inserted into the end portion of the door upper edge member having the baglike cross section and connected to the door upper edge member. The baglike cross section of the door upper edge member has a first cross-sectional portion provided on one end portion of the door upper edge member in the short side direction thereof, and a second cross-sectional portion provided on the other end portion side in the short side direction. A hold plate, which is inserted into the first cross-sectional portion to come into contact with the inner surface thereof, and a hold member, which is inserted into the second cross-sectional portion to come into contact with the inner surface thereof and formed of a resin integrally with the hold plate, are provided at the end portion of the door rear edge member.07-22-2010

20090138786COMMUNICATION CONTROL APPARATUS, COMMUNICATION CONTROL METHOD, AND COMMUNICATION CONTROL PROGRAM - A communication control apparatus transmits data to an other communication control apparatus and receives a notification as to whether the data has normally been received or not from the other communication control apparatus. The communication control apparatus includes setting changing means for changing setting of a transmission circuit when reception error which is a notification that the data has not normally been received is received from the other communication control apparatus.05-28-2009
20090175453STORAGE APPARATUS AND ENCRYPTED DATA PROCESSING METHOD - A storage apparatus has an encryption key updater for configuring an updated encryption key and identification information thereof, an encryptor for encrypting data by a specific unit according to the encryption key, a storage for adding the identification information to the encrypted data and storing the data and the identification information onto a recording medium, a reader for reading the encrypted data and the identification information, a judge for judging whether the identification information read by the reader matches the identification information configured by the encryption key updater, and a decryptor for decrypting the encrypted data and outputting the decrypted data where the judge judges that the identification information matches the identification information configured by the encryption key updater.07-09-2009
20090249100CIRCUIT SYSTEM - One aspect of the embodiment is related to a circuit system having multiple circuit blocks each of which operates upon reception of power supply. The circuit system includes multiple circuit blocks each of which operates upon reception of power, multiple switch elements which are provided respectively to the multiple circuit blocks and each of which supplies and cuts off power to the corresponding circuit block upon reception of control and a power control unit that controls each of the multiple switch elements to cause the switch element to supply and cut off power to the corresponding circuit block.10-01-2009
20090275291STORAGE DEVICE - A storage device controls transmission of test data and reception of the test data according to a protocol set for test mode upon receiving, for example, a test instruction, when a reception interface and a transmission interface are electrically connected together through a cable. The storage device verifies whether the test data transmitted from any one of a controller, a buffer, and a storage medium matches the test data received by any one of them.11-05-2009
20100127738CIRCUIT SYSTEM, CIRCUIT BLOCK, AND ELECTRONIC DEVICE - According to one embodiment, a circuit system includes an adjusted module, a circuit adjusting module, a power controller, and a set value storage module. The adjusted module operates in a circuit state adjusted by calibration. The circuit adjusting module adjusts the circuit state of the adjusted module by calibration and obtains a set value corresponding to the adjusted circuit state. The power controller stops power supply to at least the adjusted module upon transition to power saving mode and resume the power supply upon return from the power saving mode. The set value storage module non-volatilely stores the set value even in the power saving mode. The circuit adjusting module causes the set value storage module to non-volatilely store the set value upon power-on, and adjusts the circuit state of the adjusted module according to the set value upon return from the power saving mode.05-27-2010

20090063018FUEL INJECTION SYSTEM WITH INJECTION CHARACTERISTIC LEARNING FUNCTION - A fuel injection system designed to learn the quantity of fuel sprayed actually from a fuel injector into an internal combustion engine. When the engine is placed in a given learning condition, the system works to spray different quantities of the fuel for different injection durations in sequence to the engine through the fuel injector to collect a plurality of data on the quantity of the fuel sprayed actually from the fuel injector. The system analyzes the corrected data to determine an injection characteristic of the fuel injector, which may have changed from a designer-defined basic injection characteristic of the fuel injector, and uses the injection characteristic in calculating an injection duration or on-duration for which the fuel injector is to be opened to spray a target quantity of fuel.03-05-2009
