摘要： PROBLEM TO BE SOLVED: To provide a fuel pump vibration propagation damping method and device for a direct injection type internal combustion engine. SOLUTION: A fuel injector for directly injecting fuel into the combustion chamber of an engine block is suspended from a fuel rail and supported to avoid the direct metallic contact with the engine block. The fuel injector is joined to the fuel rail with a pair of seals spaced from each other to counterbalance force on the fuel injector in opposition to the longitudinal direction during operation. A large-diameter fuel reservoir and a small-diameter orifice are provided fluidly in series between a fuel pump and the fuel injector for absorbing and reducing vibration due to the pulsation of the fuel pump.

摘要： PROBLEM TO BE SOLVED: To provide a compact build-up welding device not requiring two kinds of electrodes, a heating electrode and a build-up welding electrode.
SOLUTION: An electrode 2 is formed in a disk shape; and its peripheral part discharges electricity to a structural material to conduct build-up weld repairing based on the output from an output control board. The electrode 2 is rotated in the peripheral direction by a motor 3 operated by a driving machine controller 5, and conducts the build-up welding by uniformly discharging its peripheral part. A feeding mechanism of electrode wire is not required by preliminarily recognizing a required build-up amount and preparing an electrode having an outer diameter and a thickness corresponding to the build-up volume and thus simplification of the device is realized.

摘要： PROBLEM TO BE SOLVED: To reduce the noise produced by the impact of a valve on a pump body during the opening/closing of the valve particularly in the low-speed range of an engine when the valve is held on the pump body movably between the open position and the closed position, and a valve head has a distance from a valve seat at the open position and abuts on the valve seat at the closed position to close the valve in the fuel pump of the direct injection internal combustion engine.
SOLUTION: An electromagnetic coil moves the valve to the open position when energized, and to the closed position when deenergized. A control circuit so controls the electromagnetic coil that the energization and the deenergization of the electromagnetic coil can be performed gently. Consequently, the noise of the fuel pump can be reduced while the engine is operated, particularly, in the low-speed range.

解决方案：电磁线圈在通电时将阀门移动到打开位置，并在断电时将其移动到关闭位置。控制电路对电磁线圈进行控制，可以轻轻地进行电磁线圈的通电和断电。因此，在发动机运转时，尤其是在低速范围内，燃料泵的噪声可以减小。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a natural circulation type boiling water reactor equipped with a chimney easily dismountable from a reactor pressure vessel, capable of reducing welded zones compared with the chimney of a conventional natural circulation type boiling water reactor.
SOLUTION: In this natural circulation type boiling water reactor 1, a plurality of square tubes 11b constitute the chimney 11. Namely, each of the plurality of square tubes 11b partitions each passage of a coolant over the core. Therefore, in the chimney 11 of the natural circulation type boiling water reactor 1, welded zones can be reduced, because each edge of four corners is not required to be welded in each passage, differently from the case wherein a coolant passage is partitioned by a plate material welded integrally such as a grid-like passage bulkhead in the conventional natural circulation type boiling water reactor.
