    • This object relates to a leather which is obtained by forming a coating film through the greasing step following re-tanning and dyeing and the drying step. The purpose of this object is to provide a leather, wherein the generation of free formaldehyde and acetaldehyde is inhibited, an automobile interior part using this leather and a back sizing agent for natural leather to be used for producing the above-described leather. A natural leather wherein a back sizing agent for natural leather containing a hydrazide compound optionally together with a resin (including an acrylic resin) is applied to the back of leather to exert an effect of fixing formaldehyde and acetaldehyde generated by a tanning agent, a re-tanning agent, a dye and a greasing agent, which have been incorporated into a leather, in the leather to thereby inhibit or prevent the generation of formaldehyde and acetaldehyde, an automobile interior part using this natural leather, and a back sizing agent for natural leather to be used for producing the above-described natural leather.
    • 本发明涉及通过在再鞣和染色和干燥步骤之后通过润湿步骤形成涂膜而获得的皮革。 本发明的目的是提供一种皮革,其中游离甲醛和乙醛的产生被抑制,使用该皮革的汽车内部部件和用于天然皮革的背面上胶剂用于制造上述皮革。 一种天然皮革,其中将含有酰肼化合物的任选与酰肼化合物(包括丙烯酸树脂)一起的天然皮革的上浆剂施加到皮革的背面,以发挥固化由鞣剂产生的甲醛和乙醛的作用, 皮革中已经掺入皮革中的染色剂和润滑剂,从而抑制或防止甲醛和乙醛的产生,使用该天然皮革的汽车内部部件和用于天然的背部上胶剂 用于生产上述天然皮革的皮革。

    • [Problems]To provide a lost-wax cast impeller for a supercharger having no parting line corresponding part on a hub surface and a blade surface in each space demarcated by pairs of long blades adjacent to each other and having excellent aerodynamic performance. [Means for Solving Problems]This method of manufacturing the impeller comprises a step for forming a lost form pattern formed in the substantially same shape as the impeller for the supercharger, a step for forming a mold by eliminating and removing the lost form pattern after the lost form pattern is coated with a refractory, and a step for pouring a molten metal in the mold for casting. In the step for molding the lost form pattern, a lost material is injection-molded in a space demarcated by radially arranging, toward a center shaft, a plurality of slide molds having short blade-shaped bottomed groove parts and space shapes between the pairs of long blades adjacent to each other, and the slide molds are released by moving in the radial direction of the center shaft while rotating. Thus, the parting line corresponding part is not present on any of the hub surface and the blade surface in the spaces demarcated by the pairs of long blades adjacent to each other.
    • [问题]提供一种用于增压器的失蜡铸造叶轮,其在轮毂表面上没有分型线对应部分,并且通过成对的彼此相邻的长叶片划分的每个空间中的叶片表面,并且具有优异的空气动力性能。 解决问题的方法这种制造叶轮的方法包括形成与增压器的叶轮大致相同形状的损失形状图案的步骤,通过消除和除去后面的损失形式图案来形成模具的步骤 损失的形状图案被涂覆有耐火材料,以及用于将熔融金属浇注到铸造模具中的步骤。 在用于模制失重形状图案的步骤中,将损失的材料注射到通过沿中心轴径向布置多个具有短叶片形底部凹槽部分的滑动模具和两对 相邻的长叶片,并且通过在旋转的同时沿着中心轴的径向移动来释放滑动模具。 因此,分隔线对应部分不存在于彼此相邻的成对的长叶片划分的空间中的毂表面和叶片表面中的任何一个上。
