摘要： A pneumatically operated screw driver having a moving unit rotatable about its axis by rotation of a rotor and movable axially by a pneumatic pressure. The moving unit includes a spline shaft supported by the rotor through a ball spline, and a drive bit aligned with the spline shaft and engageable with a head of a screw. The spline shaft has an annular flange portion. A movable piston is disposed concentrically over the spline shaft and movable in an axial direction thereof with respect to the spline shaft. A spring is disposed over the spline shaft and is interposed between the movable piston and the flange portion. A stop member is provided to a rotor or a frame body. If pneumatic pressure is applied to the movable piston, the latter is axially moved downwardly and is brought into abutment with the stop member. The spline shaft is also moved axially slightly after the movement of the movable piston. The shrinkage of the spring will generate shape-restoration force thereof to further move the spline shaft after the stop of the movable piston.

摘要： An air motor has a rotor rotatable in response to the pressure of pressurized air. A cylindrical rotary member is connected to the air motor for causing a rotation in synchronism with the rotation of the rotor. A rotary slider is slidable in the axial direction along the inner cylindrical wall of the rotary member. A rotational force transmitting mechanism is provided for transmitting the rotation of the rotary member to the rotary slider. A shaft has one end fixed to the rotary slider and the other end equipped with a piston and a driver bit holder. The rotational and axial motion of the rotary slider is transmitted to a driver bit held in the driver bit holder. And, a cylinder guides the axial slide movement of the piston responsive to the pressure of pressurized air applied on a pressure-receiving surface of the piston.

摘要： A combustion type power tool capable of avoiding damage to seal members and a housing to prolong a service life, and capable of enhancing operability and workability. Temperature elevation of a combustion chamber frame due to combustion of a mixture of combustible gas and air is detected by a temperature sensor disposed in a housing. If the detected temperature exceeds a preset temperature, ignition of an ignition plug is prohibited by a prohibiting unit in spite of ON operation of a trigger switch. In this state, alarming is performed by a display to notify the user of the inoperable state of the tool. Similar control can be made when the temperature sensor is disposed at a cylinder, an exhaust cover and the housing.

摘要： A main valve and a manual operating valve cooperatively control the compressed air supplied to an air motor and a piston. The main valve is responsive to the compressed air supplied from the manual operating valve via an air passage. An orifice is provided in the air passage to reduce the speed of the compressed air supplied to the main valve so that the shift movement of the main valve is delayed when the manual operating valve is closed.

摘要： A power screw driver includes a clutch mechanism composed of a coiled clutch spring so designed as to entangle a drive shaft member and an output shaft member to connect them together, thereby enabling the drive and output shaft members to rotate in unison. By the use of the coiled clutch spring, the clutch engaging operation is achieved smoothly and silently without accompanying impact blow or shock, thereby securing reliable transmission of a torque from the drive shaft member to the output shaft member. The coiled clutch spring may be activated only when the drive shaft member is rotating in the forward direction, in which instance a one-way clutch is used to undertake transmission of the torque when the drive shaft member is rotating in the reverse direction. As an alternative, a single clutch spring may be used to undertake transmission of the torque in the forward and reverse rotational directions. Alternatively, two coiled clutch springs each provided for one rotational direction may be used.
摘要翻译：动力螺杆驱动器包括离合器机构，该离合器机构由设计成缠绕驱动轴构件和输出轴构件的线圈式离合器弹簧构成，以将它们连接在一起，从而使驱动和输出轴构件能够一致地旋转。通过使用线圈式离合器弹簧，离合器接合操作平稳无声地实现，而没有伴随冲击或冲击，从而确保扭矩从驱动轴构件到输出轴构件的可靠传递。线圈离合器弹簧只有当驱动轴构件向前方向旋转时才能起动，在这种情况下，当驱动轴构件沿相反方向旋转时，使用单向离合器来承受扭矩的传递。作为替代，可以使用单个离合器弹簧在正向和反向旋转方向上进行扭矩的传递。或者，可以使用各自设置在一个旋转方向上的两个盘绕离合器弹簧。

摘要： In a vibration wave linear motor, a vibrator stably operates with a simple and small configuration. Both ends of a movable guide member are held by shaft bearing long holes to freely oscillate, and an angle of an inclination φ occurs according to the move of the vibrator. An inner wall of an erecting part of a supporting part also serves as a stopper, and regulates the move of the vibrator in a position where the inclination of the movable guide member becomes θ>φ at the maximum. As a result, the inclination of the movable guide member is always kept to be within the range of θ>φ. A problem that the inclining movable guide member contacts a portion other than a driving contacting part is prevented.
