    摘要: An apparatus for accurately measuring laser beam intensity profiles so as to permit adjusting the oscillation mode of the laser to achieve good workability of the beam. The beam from a CO.sub.2 laser generator is attenuated and applied to an infrared sensor which produces an electrical analog signal representing the beam intensity. The sensed signal is amplified and applied via an A/D converter and an interface to a computer. The computer controls a scanner which scans successive scanning lines of the laser beam profile across the sensor. The computer also produces a visual image of the laser beam intensity profile from the sensor signal. An operator veiwing such image can make an accurate and convenient measurement of the laser beam intensity profile, thereby providing a basis for quantitative analysis in quality inspection of workpieces subjected to the laser beam.

    摘要: An apparatus for detecting defects in a laser mirror by using a laser beam in order to detect any possible changes in reflectivity over the surface of the mirror. A laser beam is split by a beam splitter into one portion for scanning the mirror to be inspected and which is reflected therefrom to produce a reflection signal, the remaining portion of the beam providing a reference signal. A computer receives both signals and on the basis of comparison thereof determines the condition of the mirror because there will be incorrect reflection of the laser beam from any region of the mirror which is defective.

    摘要: An automatic notching device in a sewing machine comprises a worm engaged with a worm gear fixed to a driving shaft of the sewing machine, a driving cam having a cam portion formed with a plurality of protrusions and a cylindrical boss portion, and an actuating link pivotally moved dependant on the movement of said cam. A cutter-holding member is provided to move upwardly and downwardly by the movement of actuating link transmitted via a linkage member and a swing arm. During the movement of the cutter-holding member, the cutter cooperates with a cutter-guiding member disposed adjacent to a side of needle-guiding member, in order to effect a simultaneous notching operation in sewing a curved portion of garment. The notching device further comprises a push rod having at one end a lever and at the other end a yoke. An actuating shaft is connected at one end to said yoke and has a roller at its other end. Depending upon the position of the lever the roller is moved upwardly or downwardly. When the roller engages said cam portion it is in a notching position, whereas when it engages said boss portion it is in a non-notching position.

    摘要: A loader includes a seat bar swingable between a lowered, operator protective position and a raised, non-protective position. A pedal is movable between an operative position and a neutral position and has a plate member with a slot opened at it's top end. A pedal side crank is provided adjacent the pedal for rotation between a locking position and an unlocking position. Normally biased into the locking position, the pedal side crank has a lug member and is operatively coupled to the seat bar by virtue of a connecting rod and a seat bar side crank. Movement into the raised position of the seat bar causes the lug member of the pedal side crank to engage with the slot of the plate member of the pedal, thus locking the pedal in the neutral position.
