Abstract: PURPOSE: To obtain a roll which is highly resistant to corrosion, abrasion and cracking and withstands long-term use by forming the surface layer part of the roll of ferritic corrosion resistance steel which is alloy steel of specific amts. of C, Cr, Nb.  
     CONSTITUTION: The surface layer part of a roll is formed of ferritic corrosion resistance steel consisting, by weight %, of 0.1 C, 10.0W14.0 Cr, 0.4W1.0 Nb, and the balance substantially iron and impurities. Here, Cr is indispensable for improving corrosion resistance and oxidation resistance, and is required to be above the upper limit because the improvement in elongation and drawing by addition of Nb is effected on the higher side of Cr, and in order to provide the effect of Nb upon the improvement in impact value. However, in excess of the upper limit, the possibility of embrittleness arises in a long time at high temp. Nb converts microstructure to the single phase of ferrite, improves oxidation and corrosion resistance, increases elongation and drawing and improves high temp. impact resistance considerably. It is effective for generation and propagation of cracking. Also, it eliminates the degradation in strength by heating for a long time at high temp. Below the lower limit, martensite appears, the elongation and drawing are degraded and weldability is adversely affected.

Abstract: PURPOSE:To reduce an operating force of an eject button by pressing and moving forcibly a holder being in a set position of the lower part, in the upper direction, by a cam piece operated by the eject button. CONSTITUTION:When an eject button 17 is pushed, a cam piece 15 interlocked with said button lifts up a holder 1 against springs 11, 19, and an inclined cam surface 15a of the cam piece 15 abuts on a sliding piece 4 and pushes it up. When the holder 1 is lifted up forcibly to the middle of the upper and lower strokes of the holder, a pressing force of the spring 11 operates effectively and lifts up automatically the holder 1 to an initial state against a depressing spring 19. In this way, the stroke for lifting up forcibly the holder 1 which is held in a set position of the lower part by a prescribed pressing and energizing force, by operating the button 17 is reduced to half, and also a resistance of a spring force which is received before that time is small, therefore, an eject operating force can be reduced by that portion.
