    • A mechanical quantity sensor element making use of a stress-magneto effect of noncrystalline magnetic alloy. This mechanical quantity sensor element is manufactured by coupling a piece of noncrystalline magnetic alloy having positive magnetostriction with another material such as, for example, thermo-setting resin at a temperature exceeding an operating temperature range of the mechanical quantity sensor element, and then cooling them to the operating temperature range. Due to a difference in a coefficient of thermal expansion between the piece and the material, compression strain is preliminarily given to the noncrystalline magnetic alloy piece, and the mechanical quantity sensor element has an excellent linearity and a wide detectable range for mechanical quantities.
    • 利用非晶磁合金的应力 - 磁效应的机械量传感器元件。 该机械量传感器元件通过在超过机械量传感器元件的工作温度范围的温度下将具有正磁致伸缩的一片非晶磁性合金与另一种材料(例如热固性树脂)结合,然后冷却它们来制造 到工作温度范围。 由于片与材料之间的热膨胀系数不同,预先对非晶磁性合金片施加压缩应变,机械量传感器元件具有优异的线性度和机械量的广泛可检测范围。

    • A process for vapor phase catalytic oxidation of methacrolein to produce methacrylic acid at high yield and with stability over a prolonged period is provided. The process is characterized, in the occasion of producing methacrylic acid by vapor phase catalytic oxidation of methacrolein using a fixed bed shell-and-tube reactor, in that (1) the catalyst layer in each reaction tube is divided into at least two layers in the axial direction of the tube to provide plural reaction zones, and (2) each of the reaction zones is filled with the catalyst in such a manner that the amount of the catalytically active component per unit volume of the reaction tube decreases from the gas inlet portion toward the gas outlet portion.
    • 提供了甲基丙烯醛的气相催化氧化以高产率和长时间稳定地生产甲基丙烯酸的方法。 该方法的特征在于,通过使用固定床管壳反应器通过气相催化氧化甲基丙烯醛来生产甲基丙烯酸,其中(1)将每个反应管中的催化剂层分成至少两层 管的轴向以提供多个反应区,和(2)每个反应区用催化剂填充,使得每单位体积的催化活性组分的量从气体入口减少 部分朝向气体出口部分。
