摘要： A magnetically driving apparatus includes two magnetic units and a driving unit. Each of the magnetic units includes a magnet. The N-poles or S-poles of the magnetic units are directed to each other. The driving unit is located between the magnetic units. Each of the driving units includes a magnetically permeable element movable between an active position for magnetically attracting the magnets and an idle position clear of the magnetism of the magnets to allow the magnets to magnetically repulse each other.

摘要： A magnetic driving apparatus includes a base, two active magnetic units, a passive magnetic unit, and a pole-switching unit. Each of active magnetic units includes a rotational magnet. The passive magnetic unit includes two slidable magnets. One of the rotational magnets exerts magnetic push on one the slidable magnets while the remaining one of the magnets exerts magnetic attraction on the remaining one of the slidable magnets. The pole-switching unit includes a motor, a leading gear, two following gears, and a rack. The motor is connected to the base. The leading gear is operatively connected to the motor. Each of the following gears is connected to one of the rotational magnets. The rack is engaged with the gears so that the motor rotates the rotational magnets.

摘要： A magnetic driving apparatus includes a base, at least one passive magnetic unit, and a switching unit. The at least one passive magnetic unit includes two passive magnets movable on the base and a translation-to-rotation device for interconnecting the passive magnets. The switching unit includes two active magnetic units, and a driving unit. The passive magnets are located between the active magnetic units. Each of the active magnetic units includes at least two active magnets. The amount of the active magnets of each of the active magnetic units is the amount of the at least one passive magnetic unit plus one. The driving unit reciprocates the active magnetic units between two positions relative to the at least one passive magnetic unit so that the active magnets reciprocate the passive magnets.

摘要： A guide bar (1) for chain saws (50) includes a first guide plate (10), a second guide plate (30) and a spacer plate (20) which is sandwiched between the first (10) and second guide plates (30). Each of the first (10) and second guide plates (30) has a plurality of protrusions (11,31) extending from an outer side thereof and recesses (111,311) defined in an inner side thereof, A groove (21) is defined along an outer periphery of the spacer plate (20) and located between the first (10) and second guide plates (30) so as to receive the chain (40). The protrusions (11,31) and recesses (111,311) reinforce the structural strength of the guide bar (1) and reduce the friction between the guide bar (1) and the object to be cut.

摘要： A tubular lock comprises a lock cylinder assembly 20 and a lock core assembly 11 having lock core body 12, at least one set of flat tumbler plates. A blocking ring 22 having internal grooves 222 is located against an internal annular shoulder 213 of lock housing 21 and held in place by sleeve 23. A plurality of axial guide slots 124 is formed in the lock core body 12 accommodating axial sliding of tumbler plates 13. Each flat tumbler wafer 13 has at least one combination notch 131 which when aligned with protruding blocking teeth 221 of the blocking ring by insertion of correct key allows rotation of the lock core; when an incorrect or no key is inserted the combination notch in the tumblers is misaligned with the blocking ring and prevents rotation of the lock core. Preferably each tumbler plate 13 includes anti-cracking grooves (132, fig.12A) and a probe proof step (132, fig. 12A).
