    • There is provided a resin magnet material that has excellent flame retardancy, produces only a small amount of toxic substances when ignited, and yields very few molding defects; as well as an electron beam adjustment apparatus in which this resin magnet material is used. To achieve this object, a first invention comprises a flame-retardant resin magnet material obtained by adding (Z) an alnico-based magnetic powder or a ferrite-based magnetic powder to a flame-retardant resin composition that is itself obtained by adding heat-resistant aluminum hydroxide and antimony trioxide to a polyamide resin in the following amounts: (A) per 100 weight parts polyamide resin, (B) X1 weight parts heat-resistant aluminum hydroxide with a decomposition temperature of 280° C. or higher (where 10 weight parts
    • 提供具有优异阻燃性的树脂磁体材料,在点燃时仅产生少量有毒物质,并且产生非常少的成型缺陷; 以及使用该树脂磁体材料的电子束调节装置。 为了实现该目的,第一发明包括阻燃树脂磁体材料,该阻燃树脂磁体材料通过将(Z)阿利镍系磁性粉末或铁氧体系磁性粉末添加到阻燃树脂组合物中,所述阻燃树脂组合物本身通过加热 - 耐热氢氧化铝和三氧化锑相对于聚酰胺树脂的量为:(A)每100重量份聚酰胺树脂,(B)X1重量份耐热氢氧化铝,分解温度为280℃以上(其中10 重量份
