    摘要: An impact tool includes a body, a barrel mounted on the body and a cylinder disposed within the barrel and reciprocally moved by a drive mechanism. A communication groove is formed between the cylinder and the barrel and communicates with the outside. The cylinder includes a plurality of communication holes formed in a radial direction and spaced from each other in a longitudinal direction. A striker is reciprocally movable within the cylinder, and an air chamber is formed between the striker and the cylinder. The striker is positioned at a first position when the tool bit is not pressed on a work. The striker at the first position permits communication between the air chamber and the communication groove through any one of the communication holes so as to be prevented from idle impact. Further, the striker is movable to a second position rearward of the first position through the pressing operation of the tool bit on the work. The striker at a position rearwardly of the second position prevents communication between the air chamber and the communication groove so as to permit normal impact operation by the tool bit.

    摘要翻译: 冲击工具包括主体,安装在主体上的筒体和设置在筒体内并由驱动机构往复移动的筒体。 在气缸和筒体之间形成有与外部连通的连通槽。 圆筒包括沿径向形成的多个连通孔,并且在纵向上彼此间隔开。 冲击器在气缸内可往复运动,并且在冲击器和气缸之间形成空气室。 当工具头没有按压在工件上时,撞针位于第一位置。 在第一位置处的撞针允许通过任何一个连通孔在气室和连通槽之间进行连通,以防止空转。 此外,通过工具上的工具钻头的按压操作,撞针可以移动到第一位置后的第二位置。 在第二位置后方的位置处的撞针防止气室和连通槽之间的连通,从而允许工具钻头进行正常的冲击操作。

    摘要: An automatic release timing control system for use with a press and a cooperating feeder for feeding a web of sheet material wherein a sheet release timing and a sheet grip timing of a release mechanism in the feeder are corrected in response to the varying revolution of the press and the response time of the release mechanism, so that, even when the working speed of the press is high, the sheet releasing operation and the sheet gripping operation of the release mechanism can follow up the working speed of the press.

    摘要: A device for inspecting the external appearance of solid medicine having a solid medicine supplying section, a first drum-shaped conveying section for conveying solid medicines supplied by the solid medicine supplying section, at equal intervals so that one surface of each piece of solid medicine is observed. A second drum-shaped conveying section receives the solid medicine from the first drum-shaped conveying section and conveys the solid medicine at equal intervals so that the opposite surface of each solid medicine is observed. First and second observing units are provided adjacent to said first and second drum-shaped conveying sections for observing both surfaces of each piece of solid medicine respectively. A third observing unit is employed for observing the thickness of each piece of solid medicine conveyed by the first and second drum-shaped conveying sections at least before the piece of solid medicine reaches the second observing unit. A discriminating circuit determines whether each piece of solid medicine is acceptable or unacceptable according to observation results provided by the first, second and third observing units and a memory stores every solid medicine discrimination signal outputted on the basis of the observation results provided by the first and third observing units. The discrimination signal based on the observation result provided by the second observing unit and the discrimination signals stored in said memory are utilized for general determination as to whether the external appearance of each piece of solid medicine is acceptable or unacceptable.
