20090037044 | ELECTRONIC CONTROL SYSTEM AND METHOD FOR VEHICLE DIAGNOSIS - A vehicle diagnosis system includes an electronic control unit, which executes a diagnosing process for determining whether any abnormality is present in a vehicle based on signals from vehicle devices. When any abnormality is detected, the electronic control unit stores in an EEPROM a diagnosis result indicative of the abnormality when a storage permission flag in the EEPROM is in the on-state. The storage permission flag is turned on from the off-state when receiving a storage permission command from an external unit. Thus, the storage of the diagnosis result into the EEPROM may be permitted at the time of transmitting the storage permission command externally to the ECU. | 02-05-2009 |
20090271064 | ELECTRONIC CONTROL SYSTEM FOR VEHICLE - An electronic control unit performs self-diagnosis based on signals received from various sensors, and stores abnormality data in an EEPROM when abnormality is detected. The DTC is stored in a first memory area and a second memory area of the EEPROM, if a condition flag stored in the EEPROM is OFF and ON, respectively. The condition flag is switched from OFF (initial value) to ON, when service start data is received from a telematics service center in a period from the completion of assembling the electronic control unit to the vehicle to the start of use of the vehicle by a user. | 10-29-2009 |
20090281689 | ELECTRONIC CONTROL SYSTEM FOR VEHICLES - In an electronic control system for a vehicle, an ECU performs diagnosis, and attaches a flag to abnormality data DTC upon detection of abnormality. The flag value is 0 or 1, when a specified condition is not satisfied and satisfied, respectively. When an ignition switch is turned off, the DTC with the attached flag is stored in an EEPROM. The flag value is switched in response to a specified condition that arises between completion of assembly of the ECU to a vehicle and use of the vehicle by a user. The specified condition is set to correspond to start of telematics service to the vehicle. | 11-12-2009 |

20130090804 | ELECTRONIC CONTROL UNIT FOR VEHICLE - An electronic control unit includes a threshold acquiring element, a behavior determining element and a storing element. The threshold acquiring element acquires a threshold for defining a determination condition. The threshold is set to correspond to a road condition on which a vehicle travels. The behavior determining element determines whether a vehicle behavior satisfies the determination condition defined by the threshold. The storing element stores predetermined operation data of the vehicle when the behavior determining element determines that the vehicle behavior satisfies the determination condition. | 04-11-2013 |
20130096769 | ELECTRONIC CONTROL UNIT - An electronic control unit (ECU) includes an abnormality detection unit, a storage unit, and a communication unit. The abnormality detection unit detects a vehicle abnormality, and the storage unit stores, at the time the vehicle abnormality is detected by the abnormality detection unit, predetermined driving information of the vehicle in a memory unit. In addition, the communication unit transmits the driving information stored in the memory unit to a remote center, where the driving information is stored along with vehicle identification information for identifying the vehicle. The communication unit may interrupt a communication process that is being performed in order to transmit the driving information to the remote center after the storage control unit stores the driving information in the memory unit. | 04-18-2013 |

20080259733 | ULTRASONIC TRANSDUCER AND MANUFACTURING METHOD THEREOF - A technology capable of improving receiver sensitivity and improving insulation withstand voltage in an ultrasonic transducer is provided. An ultrasonic transducer comprises: a lower electrode; an insulator covering the lower electrode; a cavity portion disposed on the insulator so as to overlap with the lower electrode; and an upper electrode disposed so as to overlap with the cavity portion. In this ultrasonic transducer, an insulator is inserted between the upper and lower electrodes in a part not having the cavity portion. By this means, sum total of thickness of insulators between the upper and lower electrodes in a part not having the cavity portion is larger than sum total of thickness of insulators between the upper and lower electrodes in a part having the cavity portion. | 10-23-2008 |
20080274576 | SEMICONDUCTOR DEVICE AND MANUFACTURING METHOD THEREOF - A method for improving productivity when manufacturing a semiconductor device. A lower electrode, insulating films, an upper electrode and insulating films are formed on a semiconductor substrate in a sensor region. A cavity is formed between the insulator films above the lower electrode. The lower electrode, insulating film, the cavity and insulating film, and an upper electrode form a variable capacity sensor. The cavity is formed by etching a sacrificial pattern between the insulation films by way of a hole formed in a pair of insulation films. Other than in the above sensor region, a dummy lower electrode and four insulating films are formed on the TEG region on the semiconductor substrate; and a dummy cavity is formed between a pair of insulation films above the lower electrode however no conductive layer on the same layer as the upper electrode is formed on the dummy cavity. | 11-06-2008 |
20090189480 | Ultrasonic Transducer And Manufacturing Method - This invention provides a technique whereby, even if a step is produced by splitting a lower electrode into component elements, resistance increase of an upper electrode, damage to a membrane and decrease of dielectric strength between an upper electrode and the lower electrode, are reduced.
