    • An X-ray tube of the rotary anode type includes a rotary structure to which an anode target is fixed, a stationary structure fitted into the rotating member, slide bearings arranged between them and provided with spiral grooves, and a lubricant consisting of gallium alloy and supplied to the slide bearings. The rotary structure includes a first rotating member to which the anode target is connected and a second rotating member provided with the bearings. These first and second rotating members are kept coaxial to each other and connected together at their those portions which are remote from the anode target when viewed in the rotating axis direction of the target and along a heat transmitting line extending from the target to the bearings, but heat insulating clearances and are formed between the rotating members at their other portions not connected. The first rotating member is made of one of those materials which have a heat conductivity smaller than 0.1 (cal/cm.sec..degree.C.) at temperature range of 0.degree. to 500.degree. C. The second rotating member is made of alloy whose main components are iron and nickel, alloy whose main components are iron, nickel and cobalt, alloy whose main components are iron and chromium, alloy whose main components are iron, chromium and nickel, or iron alloy including iron, chromium and one of carbon, molybdenum and tungsten.

    • A filtering apparatus for processing liquids includes filtering element which is provided outside a clean liquid tank so that the clean liquid discharged through an outlet provided at the bottom of a filter tank is stored in a clean liquid tank. It is therefore possible to prevent processing powder from falling in the clean liquid tank and contaminating the clean liquid during the work of changing the filtering element and easily perform the work of changing the filtering element while maintaining the amount of processing liquid contained in the filtering element at the minimum level. It is also possible to easily perform the maintenance of the filtering element and remove the need for a maintenance space around the filter for processing liquids.
    • 用于处理液体的过滤装置包括设置在清洁液体罐外部的过滤元件,使得通过设置在过滤罐底部的出口排出的清洁液体被储存在清洁的液体罐中。 因此,在改变过滤元件的工作中,可以防止加工粉尘落入清洁液罐中,污染清洁液体,容易地进行过滤元件的变更工作,同时保持过滤元件中所含的处理液的量 在最低级别。 也可以容易地进行过滤元件的维护,并且不需要用于处理液体的过滤器周围的维护空间。
