摘要： PURPOSE:To manufacture a nonmagnetic and low-resistance Ni alloy excellent in hot workability by applying homogenizing treatment, hot working and ageing treatments to an Ni alloy ingot having a specific composition consisting of C, Si, Mn, Ti, Al, Cu, B and Ni. CONSTITUTION:The Ni alloy ingot consisting of, by weight, 0.05-0.25% C, 0.01-0.5% Si, 0.01-1.5% Mn, 0.1-0.8% Ti, 3-5% Al, 7-20% Cu, 0.001-0.05% B and the balance essentially Ni is subjected to homogenizing treatment preferably at 1,000-1,250 deg.C to reduce ingot segregation. Then hot working is applied to the above ingot preferably at 800-1,200 deg.C to carry out grain refining. Subsequently, the worked ingot is subjected, directly or after subjected to solution heat treatment, to ageing treatment preferably at 450-650 deg.C to disperse gamma prime (Ni3Al) uniformly into a matrix. In this way, nonmagnetic and low- resistance Ni alloy excellent in hot workability can be obtained.

摘要： PURPOSE:To prevent a fixed quantity of paper from being accumulated and prevent the paper from jamming, by a method wherein a paper guide frame part is rotatably fixed to a paper-discharging end of a printer so that it is rotatably moved by a pressure when the paper is accumulated. CONSTITUTION:The paper 2 discharged from the printer 3 is guided by a paper guide surface 6, and is contained into a paper-containing box 9 while being assisted in bending. When the paper 2 is not bent but remains stiff, the discharge of the paper is hindered by the guide surface 6, so that the paper is accumulated on a paper moving surface 4 of the printer 3. However, the guide surface 6 receives a pressure due to a paper-discharging force 10 of the printer 3, so that a paper guide 1 is rotatedly moved with a rotary shaft 7a as a center to a position 11 where the guide 1 does not hinder the discharge of the paper. As a result the accumulated paper 12 falls off the paper moving surface 4, so that the paper does not generate jamming.
摘要翻译：目的：为了防止固定数量的纸张被积聚并防止纸卡住，通过一种方法，其中纸引导框架部分可旋转地固定到打印机的纸张排出端，使得其被压力可旋转地移动纸张积累了。构成：从打印机3排出的纸张2由纸引导表面6引导，并且在辅助弯曲的同时被容纳在含纸盒9中。当纸张2不弯曲但保持刚性时，纸张的排出被引导表面6阻碍，使得纸张堆积在打印机3的纸张移动表面4上。然而，引导表面6受到压力由于打印机3的纸张排出力10，使得导纸器1以旋转轴7a为中心旋转移动到导向件1不妨碍纸张排出的位置11。结果，累积的纸张12脱离纸张移动表面4，使得纸张不产生卡纸。

摘要： PURPOSE:To form a print wire featuring better high-speed operability and wear- resistance by fixed application of the hard material onto a wire of Ti-Mo-Zr- Al series alloy out of the Titanium series materials. CONSTITUTION:At the extreme end of wire made of an alloy containing Mo: 11-17%, Zr: 3-7%, Al: 1.5-5.0% and Ti as an impurity drawn to 0.2-0.6phimm. with a cold-working ratio of above 30%, a hard metal tip is fixedly applied. Content of Mo less than 11% causes poor workability of print wire of a diameter less than 0.5phi because of metallographica1 reasons respecting Ti. Further, content of Zr less than 3% gives birth to poor workability because of poor ductility of the alloy. Al affects strongly a strength property of print wire. Hardness of the hard metal less than Hv 850 causes unavailability of the targeted wear-resistance and therefore, Hv 1,100 and more is necessary.
摘要翻译：目的：通过将硬质材料固定在钛系列材料的Ti-Mo-Zr-Al系合金丝上，形成具有更好的高速可操作性和耐磨性的印刷线。构成：在含有Mo：11-17％，Zr：3-7％，Al：1.5-5.0％和Ti作为杂质的合金制成的电线末端为0.2-0.6phim。冷加工率在30％以上，固定硬质金属头。 Mo的含量小于11％，导致直径小于0.5phi的印刷线的加工性差，这是因为涉及Ti的金相学1。此外，Zr的含量小于3％，由于合金的延展性差，导致加工性差。铝强烈影响印刷丝的强度性能。小于Hv 850的硬质合金的硬度导致目标耐磨性不足，因此需要Hv 1,100以上。
