    • The hydrogenated aromatic oligomer of this invention is represented by the following formula (1) (A-F)n-A  (1) (wherein A is a segment comprising mainly a polycyclic aromatic compound, a phenol and at least partly hydrogenated products of these two, F is methylene or dimethylene ether and n is a number in the range of 1-100) and obtained by the reaction of a polycyclic aromatic compound such as naphthalene with formaldehyde or a derivative thereof and a phenol in the presence of an acid catalyst followed by hydrogenation of the product aromatic oligomer. This oligomer is odorless, highly transparent and useful as an improver of the adhesiveness and vibration damping properties when incorporated in resins and rubbers and performs excellently as a vibration damping agent in a wide temperature range.

    • This invention relates to an aromatic oligomer represented by the following formula (1): (A—F)n—A   (1) wherein A is a unit comprising (a) 30-90 wt % of a bicyclic or tricyclic aromatic compound and (b) 10-70 wt % of a phenol, F is methylene or a mixture of methylene and —CH2OCH2— and n is a number of 1-100. The aromatic oligomer is obtained by and reaction of a polycyclic aromatic compound such as naphthalene and benzothiophene, a phenol and formaldehyde compound in the presence of an acid catalyst. The aromatic oligomer is odorless and useful for various applications. In particular, when incorporated in rubber or resin, the aromatic oligomer can perform execellently as a tackifier in a wide temperature range or perform excellently as a vibration damping agent.
    • 本发明涉及由下式(1)表示的芳族低聚物:其中A是包含(a)30-90重量%的双环或三环芳族化合物和(b)10-70重量%的苯酚的单元, F是亚甲基或亚甲基和-CH 2 OCH 2 - 的混合物,n是1-100的数。 芳族低聚物通过萘和苯并噻吩等多环芳香族化合物,苯酚和甲醛化合物在酸催化剂的存在下反应而得到。 芳族低聚物无臭,适用于各种应用。 特别是,当结合到橡胶或树脂中时,芳族低聚物可以作为增粘剂在宽温度范围内进行,或作为减震剂表现优异。

    • A thin film magnetic head has a media opposing surface which is adapted to be opposed to a recording medium, and includes a sacrificial layer, on a substratum that has a surface for forming the media opposing surface having at least one rail. A tracking mechanism or loading/unloading mechanism can be provided on the slider. An electrostatic actuator suitable for driving such a mechanism includes a stationary section having a plurality of teeth parallel to each other, a movable section having a plurality of teeth parallel to the teeth of the stationary section, a support spring for supporting the movable section so that the movable section can be moved with respect to the stationary section in the tooth width direction. A drive force generator moves the movable section to a position at which an electrostatic attraction force in the tooth width direction generated when a voltage is impresses between the teeth of the stationary section and those of the movable section, is balanced with the elastic force of the head suspension.
