  • Patent number: 11355812
    Abstract: A device includes a battery case (42) that stores a battery (62A or 62B), a lock mechanism (133) that is capable of fixing and holding the stored battery (62A or 62B) in the battery case (42), and an operation member (44) that is capable of performing switching operation of the lock mechanism (133) between a battery-fixed state and a non-battery-fixed state. The lock mechanism (133) includes a movable block (160) which is supported by the battery case (42) in a displaceable manner. The movable block (160) has a battery restriction portion (160b or 160c) which restricts displacement of the battery (62A or 62B) in a separation direction in a state of being displaced to a battery fixing position, and a holding force receiving portion (160d) which receives a holding force for maintaining the movable block (160) at the battery fixing position from the operation member (44) in a state where the operation member (44) is operated within a predetermined positional range.

  • Patent number: 4319665
    Abstract: A control system for an AC elevator system in which an actual speed of an elevator car is compared with a speed command and control is made so that deviation between the actual speed and the commanded speed becomes zero. The speed command is so composed that deceleration of the elevator car is gradually decreased as the car approaches to a target landing position in the stopping operation of the elevator. A motoring torque or a braking torque is additionally generated in dependence on a load on the car in a region close to the target landing position.

  • Patent number: 4101819
    Abstract: In a three phase load controlling system two bilateral switching circuits control the current in the first and the third phases; the first phase is later than the third. The second phase is uncontrolled. The gating signals applied to the bilateral switching arrangement connected in the first phase are advanced by a constant degree with respect to the voltage of the first phase. The gating signals applied to the bilateral switching arrangement connected in the third phase are synchronized with the voltage of the third phase.
