    • In a magnetic head of perpendicular magnetization type having main and sub magnetic poles arranged at both sides of a recording medium, a nonmagnetic supporter holding a high permeability magnetic thin layer of the main magnetic pole is formed by a polycrystalline sintered body substantially composed of titanium carbide and alumina. This polycrystalline sintered product well matches with a recording medium having a cobalt-chromium alloy layer so that the recording medium does not wear for a long time of use, and therefore, so that the contact surface of the main magnetic pole is hardly damaged. The same sintered body may also be used for the sub magnetic pole arranged to be in contact with the recording medium. Some structural improvements are also provided so that undesirable influence due to an adhesive layer adjacent to the magnetic thin layer is removed. One or more additional thin layers may be provided for reducing crosstalk between adjacent tracks. A magnetically shielding block is provided to prevent undesirable influence caused by an external magnetic field.
    • 在具有设置在记录介质两侧的主磁极和副磁极的垂直磁化型的磁头中,保持主磁极的高磁导率磁性薄层的非磁性载体由基本上由碳化钛组成的多晶烧结体形成 和氧化铝。 该多晶烧结体与具有钴 - 铬合金层的记录介质良好地匹配,使得记录介质长时间不磨损,因此,主磁极的接触表面几乎不被损坏。 相同的烧结体也可以用于与记录介质接触的副磁极。 还提供了一些结构改进,以便消除由于与磁性薄层相邻的粘合剂层引起的不期望的影响。 可以提供一个或多个附加的薄层以减少相邻轨道之间的串扰。 提供磁屏蔽块以防止由外部磁场引起的不期望的影响。

    • This microlens array comprises hexagonal field diaphragms in inverted-image-forming positions, i.e., microlenses, a plurality of which are arranged in the direction perpendicular to a direction of scanning, and from which rows of microlenses are configured. Further, for three rows of microlenses, microlens rows are arranged with offset by (a length S) in a direction perpendicular to the direction of scanning such that triangular portions of the hexagonal field diaphragms overlap in the direction of scanning. Furthermore, microlens row groups, which are configured from three microlens rows, are arranged with offset in the direction perpendicular to the direction of scanning in increments of a minute amount of shifting F (for example, 2 μm). Thereby, this scanning exposure device using a microlens array is capable of preventing exposure ununiformity even in the direction perpendicular to the direction of scanning.
    • 该微透镜阵列包括反转图像形成位置中的六边形场隔膜,即微透镜,其中多个沿垂直于扫描方向的方向排列,并且从其构成微行列。 此外,对于三行微透镜,微透镜排沿垂直于扫描方向的方向偏移(长度S),使得六边形场隔膜的三角形部分在扫描方向上重叠。 此外,由三个微透镜列构成的微透镜行组以微小量的移动F(例如,2μm)的增量在垂直于扫描方向的方向上偏移地布置。 因此,使用微透镜阵列的该扫描曝光装置即使在与扫描方向垂直的方向上也能够防止曝光不均匀。

    • Low-pressure fire-extinguishing liquid is converted into mist. A fire-extinguishing spray nozzle (10) comprises a main body (30) and an obstacle (36). The main body (30) has a port (40) for radially injecting the fire-extinguishing liquid. The obstacle (36) is arranged within a radial injection region (102) of the fire-extinguishing liquid radially injected from the port (40). The obstacle (36) has an outer peripheral surface formed in the shape of a truncated-conical inclined surface (62). This enables the fire-extinguishing liquid (70) radially injected from the port (40) and passing around the obstacle (36) to collide with the fire-extinguishing liquid (72) radially injected from the port (40) and reflected from the inclined surface (62) so as to produce mist (74) of fire-extinguishing liquid. When producing the mist (74) by such an action, the fire-extinguishing liquid radially injected from the port (40) may have a low pressure. As a result, it is possible to provide a fire-extinguishing spray nozzle (10) which converts the low-pressure fire-extinguishing liquid into mist.
    • 低压灭火液转化成雾。 灭火喷嘴(10)包括主体(30)和障碍物(36)。 主体(30)具有用于径向喷射灭火液体的端口(40)。 障碍物(36)布置在从端口(40)径向喷射的灭火液体的径向喷射区域(102)内。 障碍物(36)具有形成为截锥形倾斜面(62)形状的外周面。 这使得能够从端口(40)径向注入并绕过障碍物(36)的灭火液体(70)与从端口(40)径向喷射并从倾斜的(反射))反射的灭火液体 表面(62),以产生灭火液体(74)。 当通过这种动作产生雾(74)时,从端口(40)径向注入的灭火液可能具有低压。 结果,可以提供将低压灭火液转化为雾的灭火喷嘴(10)。
