摘要： Two guide members cooperatively constitute a chuck portion for holding a screw head. Opening and closing of the chuck portion is regulated depending on a mutual position between a machine body and a member into which a screw is driven. Guide pin portions of respective guide members engage with a stopper portion of a push lever until a screw is driven to a predetermined depth. The chuck potion tightly holds the screw head until a screw fastening operation is substantially finished, thereby suppressing the lifting of a machine body.

摘要： A recording/reproducing apparatus for a magneto-resistive (MR) head having a playback amplifier, including a capacitor for a dc feedback low-pass filter for dc feedback to an initial-stage transistor, and a differential amplifier (gm amplifier), and a switching device for the gm amplifier and for the initial-stage amplifier operable at the time of recording/playback switching. The timing of the switching device is deviated for shortening the switching time interval. To this end, an output of the initial-stage transistor of a playback amplifier for a MR head is compared to reference voltage Vref by a gm amplifier and the low-pass filter is constituted by transconductance gm of the gm amplifier and the capacitance of the capacitor, with the dc output of the gm amplifier being fed back to the base of the initial-stage amplifier. The delay in switching time by the charging of the capacitor caused by the difference in the rise time of the initial-stage transistor and the gm amplifier is deviated by the control signal from a control circuit to control the initial-stage transistor and the gm amplifier.

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： In carrying out precision laser-beam machining by using a laser-beam machining head driven by an additional motion-axis means 8 of a laser robot unit 1, a CPU accommodated in a robot controller 10 calculates time A+B necessary for a laser beam projecting nozzle to travel a distance between a position corresponding to a position of origin OR of a machining locus and a position corresponding to a starting point E on the machining locus at a quick-feed speed, and time C necessary for the laser beam projecting nozzle to travel the same distance in a laser-beam machining mode not including quick-feed operation, compares the times A+B and C, and provides feed motors MA and MB accommodated in the additional motion-axis means 8 with an automatic quick-feed command, when the time A+B is shorter than the time C to thereby enhance an efficiency of the laser machining operation.

摘要： An improved method for effecting cross-lamination of wide warp and weft webs is provided, wherein a continuous row of cut weft webs having a length corresponding to the width of the warp web to be cross-laminated thereto and arranged in side by side relationship is temporarily prepared on a warp material which is (1) a belt means from which said row of weft webs is transferred onto a warp web in order to be fixed thereto for effecting cross-lamination, (2) a warp web backed up by a belt means from which said row is peeled off in the state loaded on the warp web in order to be fixed thereto for effecting cross-lamination, or (3) a warp web itself to which said row is fixed for effecting cross-lamination, so that the warp material travelling crosswise over the cut weft web at a vertical distance apart therefrom and having been wetted with a liquid having adhesion property to the surface thereof facing said cut weft webs is subjected to successive reciprocating vertical motions so as to touch and pick up the cut weft webs one by one by temporary adhesion to the warp material arranged in side by side relationship, due to the adhesion property of said liquid wetting the surface of the warp material.
