    • In a thermal-type air flow measuring apparatus, a heater is set to a reference temperature which is a predetermined temperature higher than an intake air temperature detector. A flow amount detector is disposed at an upstream side of the heater with respect to a forward direction of an intake air flow. The heater is turned at a plurality of points in a direction perpendicular to the forward direction of the intake air flow and has a predetermined width in the intake air flow direction so that heat transfers less in the intake air flow direction in the heater. If the intake air flow direction reverses, the temperature distribution in the heater also reverses. As a result, an intake air amount varying in response to the air flow direction is detected by comparing the temperature of the flow amount detector with the reference temperature.
    • 在热式气流测量装置中,将加热器设定为比进气温度检测器高的规定温度的基准温度。 流量检测器相对于进气流的前方设置在加热器的上游侧。 加热器在垂直于进气流动方向的方向上的多个点处转动,并且在进气流动方向上具有预定的宽度,使得加热器中的进气流动方向上的热量传递较少。 如果进气流动方向反转,则加热器中的温度分布也反转。 结果,通过将流量检测器的温度与参考温度进行比较来检测响应于空气流动方向而变化的进气量。

    • An air flow meter disposed in an intake pipe has a bypass member having a U-shaped bypass passage, into which part of air flowing through the intake pipe is introduced. An outflow port disposed at a downstream air side of the bypass passage is surrounded at its three sides by opposing surfaces of a pair of side walls and a wall surface of a partition wall disposed at “an upstream air side of the outflow port”. Further, the outflow port is opened in an air flow direction in the bypass passage and in an air flow direction in the air flow passage. Therefore, air flowing through the bypass passage is partially discharged into the air flow passage through the outflow port gradually before joining main air flow in the air flow passage, thereby restricting decrease in air flow velocity and occurrence of turbulence in the bypass passage.
    • 设置在进气管中的空气流量计具有具有U形旁通通路的旁通部件,导入通过进气管的空气的一部分被引入。 设置在旁通通道的下游侧的流出口在其三侧被一对侧壁和设置在“流出口”的上游侧空气侧的分隔壁的壁面的相对面相对地包围。 此外,流出口在旁通通路中的空气流动方向和空气流动通道中的空气流动方向上打开。 因此,流入旁路通路的空气在与空气流路连通的主空气流之前逐渐地通过流出口排出到空气流路内,从而限制旁路通路的空气流速的减小和紊流的发生。

    • In a working nozzle for a gel coating apparatus, a nozzle plunger (15) has, in addition to a valve portion (15b), located at its lower end, for opening or shutting the small-diameter portion of a plunger insertion hole (4), a flange (16) which is located above the valve portion and can be brought into contact with or separated from an edge of the small-diameter hole portion (5). This prevents leakage of gel during shutting of the small diameter. The nozzle plunger has also a gel accommodating groove (17) provided on the outer periphery of said valve portion and adjoining to a lower surface of the flange, thereby permitting the sharp cutting of the gel when the valve shuts. The nozzle plunger has a step (25) provided at the lower end of its inner periphery and having a larger diameter than larger than the inner diameter of the valve portion, thus preventing stagnancy of seeds within the nozzle plunger.
