摘要:
Conditional base maintenance has been gaining widespread acceptance, with numerous sensors attached to equipment for constant monitoring of its operational state, the resulting sensor data being compared with those about the equipment in the normal state for a diagnosis to determine whether the equipment is currently operating normally, the result of the diagnosis being used to conduct maintenance. Conditional base maintenance can rapidly detect aging deterioration of the equipment, so that abnormal sates that were not detected before in time base maintenance can now be detected. However, although conventional diagnosis technology can distinguish between the normal state and anomaly, it has been difficult with such technology to identify causes including abnormal phenomena and parts. If it is determined that the target equipment to be diagnosed deviates from the normal state, the degree of deviation of each parameter from the normal state as the reference is calculated as an abnormal contribution ratio. A failure cause is estimated from a similarity ratio between the calculated abnormal contribution ratio and the abnormal contribution ratio of each of the failure causes collected in the past and including failure phenomena and failure parts.

A rotor includes a rotor core comprised of steel sheets that are laminated in the axial direction of the rotor core and a rotating component configured to rotate together with the rotor core. Each of the steel sheets has a positioning portion for circumferentially positioning the steel sheet with respect to the rotating component and is formed of a rolled steel material. For each of the steel sheets, the direction of rolling of the steel sheet is circumferentially offset from both imaginary lines X and Y by predetermined angles. Each of the steel sheets is shaped so that the circumferential position of the positioning portion thereof remains unchanged when the steel sheet is front-back inverted about the imaginary line X. When viewed along the axial direction, at least one of the steel sheets is front-back inverted with respect to and thus forms a mirror image of the other steel sheets.

Provided is a construction machine diagnosing system and method in which even a user who has little knowledge of any procedures and techniques for diagnosing construction machines can speedily diagnose a desired machine in a manner appropriate for particular data characteristics of the machine.A diagnosis device 10 acquires diagnostic data from a diagnostic data storage device 30, extracts data characteristics from the information contained in the diagnostic data, acquires from a diagnostic knowledge storage device 20 any diagnosing techniques considered to be effective for the data characteristics, and presents to a user the diagnosing techniques along with respective degrees of effectiveness. The user uses the presented degrees of effectiveness to select a desired diagnosing technique and conduct a diagnosis. In addition, in order to make effective use of the diagnostic knowledge stored within the diagnostic knowledge storage device 20, a diagnostic knowledge generating section 107 classifies common data characteristics by elements of diagnosing techniques and stores the classified data characteristics and the elements of the diagnosing techniques, as new diagnostic knowledge.

A handsfree apparatus performs an operation for requesting a connection of a Bluetooth connection link to a cellular phone after guaranteeing a continuous playback of music streaming data by an audio player in a time slot that does not have packet transfer of the music streaming data, if the connection request of the Bluetooth connection link to the cellular phone is generated during a time of A2DP connection that defines packet transfer of the music streaming data with the audio player. The connection request of the Bluetooth connection link to the cellular phone is thus handled appropriately without interrupting a continuous playback of the music streaming data.

To enhance the balance in weight of the right and the left of the body of a four-wheel vehicle. In a four-wheel vehicle, an engine is supported by a body frame. A swing arm is swingably attached to the body frame. Rear wheels are supported by the swing arm. A rear cushion unit is attached between the rear of the body frame and the side of the rear end of the swing arm. Power from the engine is transmitted to the rear wheels via a rear propeller shaft. The center of the engine (that is, an axis of a crankshaft) and the rear cushion unit are set on one side and the rear propeller shaft is set on the other side respectively with respect to a center line of the body extending in a longitudinal direction of the body.

There is provided a method of producing a rare earth salt of a dialkyl phosphate or a rare earth salt of dioleyl phosphate of a high purity useful as a polymerization catalyst of a conjugated diene compound by directly reacting a rare earth oxide or a rare earth hydroxide with a dialkyl phosphate or dioleyl phosphate of a high purity. In the invention, the rare earth oxide or rare earth hydroxide is reacted with the dialkyl phosphate or dioleyl phosphate of a high purity in a non-polar solvent in the presence of at least one compound selected from a halogenated hydroacid, phosphorous acid and a rare earth halide made from the same element as in an objective product as a catalyst.

The FX index calculation server calculates the index data ISIndex(Cn)(tc) indicating its strength about each currencies, based on the rate data RD(Cn/Cm) of 28 currency pairs inputted from the RD generation server. FX automatic trading server specifies the currency pair satisfying the condition that index data ISIndex(Cn) of both of selling currency and buying currency indicates near zero (near zero), the index data ISIndex(Cn) of the buying currency is up-trend, and the selling currency is down-trend.
摘要:
At least one of outbound call history data, inbound call history data, and phone book data is transferred to a handsfree apparatus for use in a vehicle at a predetermined timing for the purpose of obtaining near realtime update of the inbound/outbound call history data from a cellular phone. By utilizing simultaneous connection of HFP and PBAP, the handsfree apparatus establishes a Bluetooth communication with the cellular phone through HFP first, and then establishes another communication through PBAP simultaneously, for receiving the inbound call history data and the outbound call history data stored before establishing the Bluetooth communication from the cellular phone. The handsfree apparatus can thus be capable of placing a call by using the outbound call history data and the inbound call history data stored in a work memory after receiving those data.
