  • Publication number: 20210158979
    Abstract: A pit gate includes a gate body which is inserted between a pool portion storing water and a canal portion connected to the pool portion and is configured to change a flow state of the water, and a seal portion (6) which is accommodated in a groove-shaped accommodation recess formed in the gate body and seals between the pool portion and the gate body. The seal portion (6) includes a low-rigidity portion (10) which is relatively easily deformed by a load according to a water pressure from the pool portion side, and a high-rigidity portion (11) which is provided on the pool portion side of the low-rigidity portion and is not easily deformed relatively by the load.

  • Patent number: 5184262
    Abstract: The present disclosure is relative with a recording and/or reproducing apparatus employing a tape, such as a magnetic tape, as the recording medium, and provides a mode switching mechanism for such apparatus. The mechanism includes a swing arm provided with a transmission gear selectively rotated in dependence upon the rotational drive direction of a sole reel motor, a cam gear formed with interrupted portions and cam surfaces associated with these interrupted portions and adapted for selectively switching predetermined operational modes by the cam surfaces in dependence upon its rotational angular positions, a biasing member for rotationally biasing the cam gear, and a cam gear retention member for retaining the cam gear at a predetermined angular position. The reel shaft is rotationally driven by means of the transmission gear of the swing arm by driving the reel motor in the forward direction.

  • Patent number: 4925127
    Abstract: In a drive mechanism for driving tape recorder reel bases wherein a mode-change lever is operated to change modes and a drive gear rotatably mounted to the change lever selectively engages one of the pair of reel bases, a reciprocating brake member in provided that is capable of engaging the reel bases in a return position to lock the reel bases. Further engagement portions for engaging the brake member with the change lever are provided, so that the drive gear engages one of the reel bases only after the brake member has been disengaged from the pair of reel bases and, on the other hand, the brake member engages the pair of reel bases only after the drive gear has been disengaged from the one of the reel bases.

  • Patent number: 4896234
    Abstract: A mode-change mechanism for a tape recording and/or reproducing apparatus of the auto reverse type requires only one partially toothless gear with at least four, toothless peripheral portions in order to change modes of operation of the apparatus. The gear with the partially toothless peripheral portions is rotated only in one direction, and rotates in turn from each locked position to its next locked position in selecting the various modes of operation, so that a stop mode, a forward reproducing or recording mode, a reverse reproducing or recording mode, a fast forward mode, and a rewind mode are selectively obtained.

  • Patent number: 4547823
    Abstract: A feather-touch mode changer having low power requirements and being capable of selectively providing a plurality of modes of operation of a tape recording/reproducing apparatus, has two changing mechanisms which are each of the type that includes a rotatable changing gear with a toothless gap, a selectively actuable trigger for causing initial angular displacement of the changing gear from an inactive position in which the toothless gap faces a drive gear to an actuating position in which the changing gear engages the drive gear, and an actuating lever that moves in a response to the rotation of the changing gear by the drive gear. The two changing mechanisms are selectively actuable, and a single drive gear is positioned for engagement with both changing gears. Each of the two changing mechanisms has associated with it a selectively energizable electromagnetic device and a locking lever that moves into a locking position in response to movement of the respective actuating lever.
