摘要： A chip removing device for a multi-head machine tool which is reduced in cost, facilitates maintenance thereof and allows adjustment of the distance between adjacent working heads by a comparatively great amount. The device comprises a duct having a slit formed in a lower wall thereof, and an expansible shutter for normally closing the slit. A connecting pipe extends upwardly from each of the working heads, and upper end portions of the connecting pipes extend in an airtight condition through the shutter into the duct. When a working head is moved, the shutter is partially expanded and contracted following the working head to maintain the closed condition of the slit. A seal plate is secured horizontally within the duct and disposed commonly to the working heads. The connecting pipe of a working head at an upper position is pressed at an upper end opening thereof against the seal plate to close the upper end opening in an airtight condition, but the upper end opening of the connecting pipe of another working head at a lower position is spaced away from the seal plate and is in an open condition.

摘要： An apparatus for providing a warning of the rotation of a spindle for a machine such as a wood working machine which gives a warning while a spindle continues to rotate due to inertia even after a motor driver for a spindle motor for rotating the spindle is interrupted thus enhancing the safety of operation of the machine. The apparatus comprises a warning device for warning that the spindle is rotating, a rotation detecting device for detecting rotation of the spindle and continuously generating, while the spindle is rotating, an electric signal independently of whether the motor driver is operative or inoperative, and a controller for discriminating between the presence and absence of an electric signal from the rotation detecting device and controlling the warning device in accordance with a result of the discrimination.

摘要： A workpiece is placed on a plurality of supporting cylinders which are projected upwardly from an upper plate or a hollow table body. All of the supporting cylinders normally assume a lowered position at which lower end faces thereof contact seat portions in a chamber of the table body so that attracting pads provided at upper ends of the supporting cylinders are disconnected from the chambers. Accordingly, even if the chamber is put into a negative pressure condition, the workpiece is not attracted to the attracting pads. Then, compressed air is supplied to the pneumatic cylinders of those supporting cylinders which fall within a horizontal area of the workpiece to lift those supporting cylinders. Consequently, the lower end faces of those supporting cylinders are spaced away from the seat portions to allow communication between the attracting pads and the chamber by way of air sucking passageways formed in the supporting cylinders to suck air through the attracting pads. As a result, the workpiece is attracted to the attracting pads and thus fixed to the lifted supporting cylinders.
摘要翻译：将工件放置在从上板或中空台体向上突出的多个支撑筒上。所有支撑筒通常呈现下降位置，在该位置，下端面接触台体的室中的座部，使得设置在支撑筒的上端处的吸引垫与室分离。因此，即使室处于负压状态，工件也不会吸引到吸引垫。然后，将压缩空气供给到落在工件的水平区域内的支撑气缸的气缸，以提升这些支撑气缸。因此，这些支撑筒的下端面与座部分隔开，以便通过形成在支撑筒中的空气吸入通道来吸引吸引板和腔室之间的连通，以通过吸引垫吸入空气。结果，工件被吸引到吸引垫并因此被固定到提升的支撑圆筒上。
