Abstract: A laser scanning apparatus is provided with a laser diode that is driven to emit a laser beam, a scanning optical system that scans the laser beam emitted by the laser diode on a surface to be scanned, and a controller that drives the laser diode by supplying electrical current to the laser diode. The controller supplies an extra electrical current to the laser diode only at an initial stage of driving of the laser diode so as to cancel an effect of a rising delay of its output intensity.

Abstract: A method of manufacturing a powder, by which it is possible to adjust the strength of the obtained powder is provided. The manufacturing method of a powder involves a step of preparing a slurry containing agglomerated particles of a synthetic material which is produced by reacting a first material and a second material under agitation, and a step of drying the slurry to obtain a powder of the synthetic material. The method has a feature that the particle size of the agglomerated particles is adjusted by, in the step of preparing a slurry, controlling agitation power for agitating the slurry. In the step of preparing a slurry, it is preferable that the slurry is initially agitated at a first agitation power, and at the time when the viscosity of the slurry approaches its maximum value, or at the time when the pH value of the slurry reaches the vicinity of the isoelectric point of the synthetic material, the agitation power is lowered from the first agitation power to a second agitation power. Further, it is preferable that before or after the completion of the reaction of the first material and the second material, the agitation power is increased from the second agitation power to a third agitation power.

Abstract: The digital camera is adapted to generates a stereoscopic pair of images from a first image taken from a first camera location and a second image taken from a second camera location. The digital camera includes an imaging device for capturing an image of the object to be taken, an optical system for forming an optical image of the object and a processor for controlling the digital camera. The processor determines a distance from the digital camera to the object, or object distance, from the position of a focusing lens of the optical system. The processor further calculates a distance for which the digital camera should be moved after the first image is taken to be located at the second camera location. The distance for which the digital camera should be moved is displayed on an LCD monitor to inform the user of the digital camera.
