    • A positive photoresist developer containing a basic compound and from 10 to 10,000 ppm of a non-ionic surfactant represented by formula (I): ##STR1## wherein X represents an oxyethylene group; Y represents an oxypropylene group; R represents hydrogen, an alkyl group containing from 1 to 8 carbon atoms, R', or ##STR2## R' represents --O--(X).sub.m (Y).sub.n --H; R" represents R' of an alkyl group containing l carbon atoms; m and n each is an integer from 1 to 50, provided that m:n is from 20:80 to 80:20; p is 0 or 1, and q and s each is o or an integer from 1 to 4, provided that p+q+s=4; and l is an integer from 1 to 4; and r is an integer from 1 to 8, provided that l+r is an integer of 9 or more. The developer has superior art in forming properties, and prevents film residues, surface layer peeling, and film reduction.

    • A structure having a shaft and a paper retaining roller mounted on the shaft for use in a printer. The structure further includes a retaining element mounted on the shaft so as to be opposed to the roller for retaining the roller in a given axial position on the shaft. The roller is rotatable about the shaft and has a flange at its one end. The retaining element has a plurality of resilient retaining arms and its one end to hold the flange rotatably. At the opposite end, the retaining element is also provided with a plurality of resilient arms which are in frictional engagement with the outer periphery of the shaft. The roller can be slid axially along the shaft when a force greater than a given magnitude is applied thereto.
    • 一种具有安装在轴上用于打印机的轴和纸张保持辊的结构。 该结构还包括安装在轴上的保持元件,以便与辊相对,用于将辊保持在轴上的给定轴向位置。 滚筒可绕轴旋转,其一端具有凸缘。 保持元件具有多个弹性保持臂,其一端可旋转地保持凸缘。 在相对端,保持元件还设置有与轴的外周摩擦接合的多个弹性臂。 当施加大于给定大小的力时,滚子可以沿轴滑动。
