Abstract: A spinning reel wherein a flyer is rotated by the rotation of a handle and a spool reciprocates back and forth. The reciprocating motion of the spool is decelerated by means of a reduction gearing relative to the rotation of the flyer which is rotated by the handle, to narrow a cross winding pitch of the fishing line wound round the outer peripheral surface of the spool.

Abstract: A safe of the present invention is easily locked or unlocked by the rotational force of a drive motor in accordance with a signal input from the outside of the safe. A locking mechanism is provided within the door. A lock bar is provided with a lock bolt on one end thereof which protrudes from the door and effects locking engagement between the door and the safe body. At ordinary time, the lock bolt is urged to the locking engagement. The drive motor is controlled by a control circuit which receives a safe open/close command signal from the outside. A driving means is revolved by the drive motor and when it engages a drive arm provided on the lock bar, the driving means moves the lock bar against the urging force, thereby releasing the locking engagement of the lock bar.

Abstract: A rotary electric tool in which a differential gear mechanism is mounted within a gear case fixed to a housing for example; projections are formed on the outer peripheral surface of an internal gear of a final planetary gear mechanism in the differential gear mechanism, the said projections being brought into engagement with a projection-formed surface of a torque adjusting cam; the internal gear and the torque adjusting cam can be changed in relative position axially by reaction force of the internal gear; and the rotation of an output shaft is changed over between high and low speed conditions according to an axial displacement of the internal gear.

Abstract: A differential gear mechanism is mounted within a gear case fixed to a housing, an intermediate gear and a clutch mechanism are disposed on at least one output side, and a rotation changes for changing over the rotation of both output shafts between synchronous rotation and independent rotation according to increase or decrease in load relative to a present torque value.
