    • The cloth piece transfer apparatus with side inverter of the invention is applied to the case of continuous feed of cut cloth pieces into a sewing machine or the like. Pickup 14 pinches holds and lifts the rear portion of the cloth piece N in the process of transfer of the cloth pieces N supplied and supported in horizontal position in uneven sides on a transfer device 4. A rodless cylinder 7 moves the pickup 14 in the transfer direction at a speed faster than the transfer speed of the transfer device 4. The cloth piece N moved by this rodless cylinder 7 is brought into contact with an inverting member 18 disposed beneath the middle position of the moving route of the pickup 14, and the sides of the cloth piece N are inverted. The inverted cloth piece N is dropped and supported on the transfer device 4. It enhances the transfer efficiency and is enable to transfer by inverting the sides without disturbing the interval of the cloth pieces supplied continuously.
    • 具有本发明的侧面逆变器的布片传送装置适用于将切布连续送入缝纫机等的情况。 拾取14个夹持件在传送装置4的不平坦侧的水平位置的布料N的传送过程中保持和提起布料N的后部。无杆筒7在传送中移动拾取器14 方向以比传送装置4的传送速度快的速度。由该无杆气缸7移动的布料N与设置在拾取器14的移动路线的中间位置下方的翻转部件18接触, 布件N的两侧倒置。 倒置布N落下并支撑在转印装置4上。它提高了转印效率,并且能够通过翻转边而不会干扰连续供给的布料的间隔而进行转印。

    • A getter for use in a sealed contact chamber consists of a porous getter material which acts to adsorb substances which could create resistive films on electrical contacts. By disposing such a getter within the contact chamber of a switching device, such as an electromagnetic relay, molecules of, for instance, organic compounds, may be selectively and over long terms adsorbed to the getter and thus kept away from the contacts. The selective adsorption of such molecules is achieved by a porous getter material in which the majority of the pores have diameters greater than 3 nm and smaller than 100 nm, with the mean value of pore diameter ranging from about 7 nm to about 20 nm. The getter material may be substantially Al.sub.2 O.sub.3.
