  • Publication number: 20190305639
    Abstract: A rotary electric machine includes a rotor, a stator including a stator core and a stator coil attached to the stator core, the stator being disposed opposed to the rotor, and a case accommodating the rotor and the stator. In the stator coil, coils of a plurality of phases are connected by a neutral point bus bar. The neutral point bus bar is provided at a coil end protruding in an axial direction from one end surface of the stator core. A cooling pipe for cooling the stator coil is provided inside the case. The cooling pipe includes a first refrigerant supply hole for discharging a refrigerant toward the coil end and a second refrigerant supply hole for discharging the refrigerant toward the neutral point bus bar.

  • Patent number: 9376996
    Abstract: A problem exists that in the case that a prior injection (a pilot injection B or a previous injection C) before a main injection A is executed when an engine is driven at a low load, a defective ignition and a defective combustion tend to be caused, an amount of carbon monoxide (CO) in an exhaust gas becomes excessive, and the carbon monoxide is discharged as white smoke. An engine device is mounted to a working vehicle, and a common rail type fuel injection device which injects fuel to the engine at multiple stages during one combustion cycle. The common rail type fuel injection device does not execute the prior injections B and C coming before the main injection A in the case that a load applied to the engine is in a low load state in which a load is lower than that at a working time by the working vehicle.

  • Publication number: 20130333491
    Abstract: A liquid sample introducing apparatus capable of executing a process with high reliability and high speed is realized. An injection valve includes a sample storage loop connected to a mobile phase flow passage for supplying a sample to a detector of a liquid chromatograph apparatus. A sample is sucked in a needle through a valve and a pipe by a syringe, being introduced to the sample storage loop, being supplied to the mobile phase flow passage. A washing solution from a washing solution bottle is supplied to the needle by a washing unit through the valve and the pipe to wash the inner wall of the needle. The washing solution from the washing solution bottle is supplied to a washing tank by the washing unit through the valve and a pipe to wash the external wall of the needle in the washing tank.

  • Patent number: 6856917
    Abstract: A method of properly correcting a base line. A concept of flexibility of a base line is introduced as an input index and a gravitation is presumed between the base line and signal data which is measured, thereby constructing a method of correcting the base line which changes gentler than a change in signal with respect to time in a peak area and which is sensitive to an area where a value of the signal data is small. A base line like a natural and smooth curve which isn't easily influenced by a local change in signal such as noise or the like can be set by an input of the flexibility.
