    • A hydraulically actuated lockup clutch is arranged between the cores of the pump and turbine elements of a torque converter for directly coupling them together for operation above the clutch point. For engagement and disengagement of the lockup clutch, which can be of the multiplate type, the turbine element is moved toward and away from the pump element under the control of a control valve which selectively communicates a clutch actuating chamber within the converter with an external pump assembly and with a fluid drain. Alternatively, a clutch actuating chamber can be formed between the core of the pump or turbine element and a movable pressure plate, so that the latter may travel toward and away from the former for engagement and disengagement of the clutch.
    • 液压驱动的锁止离合器布置在泵的芯和扭矩转换器的涡轮机元件之间,用于将它们直接联接在一起以在离合器点上方操作。 对于可以是多种类型的锁止离合器的接合和分离,在选择性地将转子内的离合器致动室与外部泵连通的控制阀的控制下,涡轮机元件朝向和远离泵元件移动 装配和排水。 或者,离合器致动室可以形成在泵或涡轮机元件的芯部和可移动的压力板之间,使得后者可以朝向和远离前者移动,用于离合器的接合和分离。

    • A braille printer that embosses braille characters line by line, in which embossing dies formed in the form of a line on which a plurality of projections or recesses for embossing braille characters, and debossing dies, on which a plurality of projections or recesses are formed in a line, are made to face each other, and the recesses and projections at positions corresponding to printing signals are pressed against each other. Cams for making the embossing dies move forward are disposed at both end positions of a line of characters below each of the embossing dies which are held at embossing positions in such a manner as to be movable forward or backward. The contour of each of these cams at both end positions of the line of characters have an apex, each of these apices being the same distance from a cam shaft. The apex of one of the cams is formed to be continuous over a predetermined rotational angle, and the apex of the other cam is formed so as to have a phase difference relative to the starting point of the range of the predetermined rotational angle.

    • A braille printer that embosses braille characters by a method wherein a paper feed mechanism using a motor is disposed in the entry of a paper feed passage, a motor controler for feeding paper on which braille characters are embossed to an emboss start position according to one dot line spacing and character line spacing is mounted thereto, and the projections and recesses of both the dies at positions corresponding to the braille signals at an embossing position in the midway of the paper feed passage, wherein there are disposed a lead-edge position sensor for detecting the lead-edge position of paper is disposed in the paper-feed passage, and an obverse-/reverse-surface indicator for outputting an obverse-/reverse-surface indication signal indicating which one of either or the obverse surface or reverse surface of the paper should be printed, and an initial paper-feed controller for, in response to a detection signal from the leading-edge position sensor and the obverse-/reverse-surface indication signal, outputting an initial paper-feed termination signal to the motor controller when the paper is fed to embossing positions which are shifted from each other so that the braille characters on both sides of the paper will not overlap.
