    • An object of the invention is to provide a porous filter cartridge that hardly involves the contamination problem, provides an economic advantage, and is able to achieve efficient filtration and extraction without breaking. The object is accomplished by a porous filter cartridge including a bottomed cylindrical cap 5 with an outlet opening 29 at the bottom and a porous filter held inside the cap 5 on the bottom. At the bottom of the cap 5 a plurality of ribs 35, 37, and 39 are arranged radially about the outlet opening 29 in a standing condition to support the porous filter. At least some of the ribs are connected to each other at the center of the outlet opening 29 to span the outlet opening 29 to form a junction 43. The junction 43 has a top surface 41 convex to the porous filter side.
    • 本发明的目的是提供一种几乎不涉及污染问题的多孔过滤器滤芯,提供了经济上的优点,并且能够在不破裂的情况下实现有效的过滤和提取。 该目的是通过一种多孔滤筒来实现的,所述多孔滤筒包括底部圆柱形盖5,底部具有出口开口29,并且多孔过滤器保持在底部的盖5内。 在盖5的底部,多个肋35,37和39在静止状态下围绕出口29径向布置以支撑多孔过滤器。 至少一些肋在出口开口29的中心处彼此连接以跨越出口开口29以形成结43。接合部43具有凸出于多孔过滤器侧的顶表面41。

    • There is provided a flexible tube for an endoscope, including a framed structure unit having a plurality of joint members rotatably coupled to each other so that the framed structure unit is able to bend freely, each joint member having a form of a short cylinder, a reticulated tube that is reticulated with thread and is formed to cover the framed structure unit, and a flexible sheath that has flexibility and is formed to cover the reticulated tube. Further, a cross section of an outer surface of the flexible sheath has a circular shape, and a cross section of an outer surface of each joint member has a non-circular shape so that a wall thickness of the flexible sheath has a thicker part in a particular direction about an axis line of the flexible tube than another part of the wall thickness of the flexible sheath.
    • 提供了一种用于内窥镜的柔性管,其包括框架结构单元,该框架结构单元具有可相互可旋转地联接的多个关节构件,使得框架结构单元能够自由弯曲,每个关节构件具有短圆筒形状, 网状网状网状网状网状网状,形成为覆盖框架结构单元,柔性护套具有挠性,形成为覆盖网状管。 此外,柔性护套的外表面的横截面为圆形,并且每个接头构件的外表面的横截面具有非圆形形状,使得柔性护套的壁厚具有较厚部分 关于柔性管的轴线的特定方向比柔性护套的壁厚的另一部分。

    • The discharge pressure value is made to smoothly approach the predetermined pressure value and once the discharge pressure value reaches the predetermined pressure value, the fluctuation of the discharge pressure value is decreased. In case the difference C between the discharge pressure value P(B) of the pneumatic regulator and the predetermined pressure value A is relatively large, the solenoid valve 31 is driven by the pulse-width modulation signal D and hence, the rapidity of the input and output response (the variation characteristics of the pressure detection signal B relative to the predetermined pressure signal A) is held, while in case the discharge pressure value P is close to the predetermined pressure value Q, the solenoid valve 31 is driven by the pulse frequency modulation signal J and hence, the amount of excess, a so-called overshoot can be decreased and even after the discharge pressure value P reaches the predetermined pressure value Q, the fluctuation of the discharge pressure value P, namely, the ripple can be decreased.
    • 使排出压力值平稳地接近预定压力值,一旦排出压力值达到预定压力值,则排出压力值的波动减小。在排出压力值P(B) 气动调节器和预定压力值A相对较大,电磁阀31由脉冲宽度调制信号D驱动,因此输入和输出响应的快速性(压力检测信号B相对于 保持预定压力信号A),而在排出压力值P接近预定压力值Q的情况下,电磁阀31由脉冲频率调制信号J驱动,因此,过量的量, 即使在排出压力值P达到规定的压力值Q之后,称为过冲也能够减小放电的波动 压力值P即波动可以减小。
