摘要:
A palm grip random orbital sanding machine having a housing and an electric motor disposed in the housing which drives an attached platen along a random orbital path. An exhaust fan disposed in an exhaust chamber produces an air flow from the vicinity of the platen out through an exhaust port. The housing has a pair of longitudinal slots provided on opposite sides thereof which removably receive the legs or side members of a U-shaped debris container. Each side member of the debris container has an entrance port coincident with the exhaust port of the exhaust chamber, and means for filtering the debris from the air flow exiting the side members. The commutator and brushes of the electric motor are disposed intermediate the longitudinal slots and the brushes are disposed parallel to the longitudinal axis of the sanding machine.

A clamp (20) and method for making the same are disclosed. The clamp (20) has a pair of jaws (42,44), a pivot (46) and an actuator (48). Each of the jaws (42,44) has a distal end (54,56) and a clamping end (50,52). The jaws (42,44) are pivotally connected by the pivot (46) such that the actuator (48) can displace the distal ends (54,56) relative to one another causing the clamping ends (50,52) to pivot together to retain the end of a blade therebetween. Preferably, the actuator (48) is a thumbscrew and the pivot (46) is a pivot pin cooperatively retained by respective pivot apertures (60,62) located in each of the jaws (42,44). Alternatively, the pivot (46) may be tenon (164) formed on one jaw (144) and a mortise (162) formed in the other jaw (142), the tenon (164) being pivotally retained within mortise (162). The clamp (20) is manually operable to clamp the scroll saw blade without the use of separate tools such as a screw driver or an Allen wrench.

A display device, which is adapted for time-division driving and is free from occurrence of crosstalk, includes a pair of substrates which are arranged to be opposite to each other and at least one of which is transparent, electrodes provided respectively on surfaces of the substrates facing each other, and a material which is sandwiched between the electrodes and the light transmitting quantity of which is changed by an electric field applied between the electrodes. The electrodes formed on the surfaces of the substrates facing each other constitute scanning electrodes and signal electrodes which intersect each other to form display portions. The signal electrodes constitutes independent electrodes formed independently of each other in units of display portions. Outside leads of the respective independent electrodes are passed through the substrate provided with the electrodes and are led out to the back surface of the substrate.

A calibration method calibrates a stereo camera. The calibration method includes: measuring a relative position between the stereo camera and an object that is placed so as to fall within an image capturing area of the stereo camera; acquiring a captured image that is captured by the stereo camera and includes the object; and determining a calibration parameter for calibrating the stereo camera based on the relative position and the captured image.

To provide continuous fiber-reinforced thermoplastic pellets having a good dispersion property of a reinforcing fiber bundle in injection molded articles and capable of achieving a satisfactory outward appearance of the injection molded articles and satisfying a mechanical strength of the injection molded articles by fully exerting the reinforcing effect, and a manufacturing method of the same.In continuous fiber-reinforced thermoplastic resin pellets manufactured by letting a long reinforcing fiber bundle be impregnated with molten thermoplastic resin and pultruding the resin-impregnated reinforcing fiber bundle with twisting, followed by the cutting of a rod-shaped composition formed of the twisted resin-impregnated reinforcing fiber bundle into pellets, a volume filling ratio Vf, which is a proportion of a cross section area of the reinforcing fiber bundle in a cross section area of a pellet cross section in a direction perpendicular to a pellet longitudinal direction, is in a range of 70% to 20%, and a twisting pitch P given by P=L/d (where L is a traveling length of a twist in a rod-shaped composition longitudinal direction per rotation of the rod-shaped composition, and d is a diameter of a circle comparable to an area of a rod-shaped composition cross section) is in a range of 2.5 to 36 (m/rev·m).
