A chain saw brake device that can instantly halt the rotation of a cutting chain when a motor drive switch is turned off. The chain saw brake device includes a brake band wound around a brake drum, such that by operating a hand guard and pulling the forward end of the brake band, the brake band is tightened around the brake drum, thereby stopping the cutting chain. The rear end of the brake band is fixed to a bent rod, and the bent rod is urged rearwardly by a coil spring when the drive switch is turned off, causing the brake band to tighten around the brake drum. By activating a trigger lever, the movable member, engaged with the trigger lever, is moved forwards, thereby pushing forwards the bent rod, and loosening the brake band.

A laser casting apparatus includes a laser light source, a phase disturbing device for disturbing a phase of laser light output from the laser light source, and a beam forming device for forming a beam of a predetermined shape. The formed beam is cast on a work after decomposing the laser light in to beams each having a small area and then superposing the decomposed beams. The phase disturbing device disturbs the phase of the light in a manner so that the superimposed beam formed of the decomposed beams has a uniform energy distribution without interference fringes.

An image-processing device includes a processor and a memory. The memory stores computer-readable instructions therein. The computer-readable instructions cause the image-processing device to identify a first region and a second region in a target image. The first region represents an encircling line for identifying a specific sub-region in the target image. The first region includes a plurality of pixels. The second region includes an inside region that is surrounded by the first region, and an outside region that is outside the first region. The image-processing device further performs changing a color value of a first target pixel included in the plurality of the pixels using a first internal pixel and a first external pixel.
