    • Initial calibration is performed only under normal-temperature environment, and accurate current control is performed under practical use temperature environment. A temperature sensor 171 is arranged close to a current detection resistor 126 having predetermined temperature characteristics. Resistance values are estimated in a calibration environment and a practical use environment, an actually measured load current in the calibration environment corresponding to a target load current is stored as control characteristic data, a corrected target current corresponding to the target load current is calculated, and a converted target current based on a change ratio of current detection resistance is controlled as a target current for current control. A resistance change amount by heat generation of the current detection resistor 126 which cannot be entirely detected by the temperature sensor 171 is corrected in control characteristic data, such that linearity of control characteristics is improved.
    • 初始校准仅在常温环境下进行,在实际使用温度环境下进行精确的电流控制。 温度传感器171布置在具有预定温度特性的电流检测电阻126附近。 在校准环境和实际使用环境中估计电阻值,将与目标负载电流相对应的校准环境中的实际测量的负载电流存储为控制特性数据,计算与目标负载电流相对应的校正目标电流,以及 基于电流检测电阻的变化率的转换的目标电流被控制为用于电流控制的目标电流。 在控制特性数据中校正由温度传感器171不能完全检测的电流检测电阻器126的发热的电阻变化量,使得控制特性的线性提高。

    • A fuel injection valve includes a nozzle body and a plate. The nozzle body includes an injection orifice, through which fuel is injected, a needle that controls the injection through the injection orifice, and a needle-receiving bore that receives the needle. The plate is adjacently provided to the nozzle body for defining a fuel passage therein, through which fuel is supplied to the needle-receiving bore. The plate has an annular groove, which connects the fuel passage with the needle-receiving bore, at an end surface of the plate toward the nozzle body.

    • In a transmission chain having series-connected a TSC unit, an encoder, a transmission path, a decoder, and an up-converter, characteristic value extracting units are connected to input/output points A, B, C, and D of these transmission processing units respectively. Each characteristic value extracting unit extracts characteristics like an average value m and a variance σ2 of luminance of a picture, for example. These characteristic values are transmitted to a central monitoring unit via a low-speed line. A characteristic value comparator compares the characteristic values. When a difference equal to or larger than a predetermined threshold value has occurred in the characteristic values, the characteristic value comparator decides that an abnormality has occurred in the image in transmission. According to the present invention, it is possible to provide an apparatus for assessing quality of a picture in transmission and an apparatus for remote-monitoring picture quality of a picture in transmission that are capable of assessing the picture quality of a transmission picture in high precision, during an actual transmission of the picture.
