Abstract: An ophthalmological image processing apparatus acquires a plurality of images of a subject eye photographed in a scanning-type imaging optical system, sets any one of the plurality of images as a template, sets corresponding points or corresponding regions between an image of the subject eye and the template at a plurality of positions of each of the image of the subject eye and the template, calculates a movement amount of each of the corresponding points or each of the corresponding regions, and corrects a distortion of the image of the subject eye with respect to the template based on the movement amount of each of the corresponding points or each of the corresponding regions.

Abstract: A game system includes a processor including hardware. The processor performs: a moving body process of moving a moving body in a map of a game space; a game process that is a process of a game where a user is allowed to gain containers arranged in the map while moving the moving body in the map; and a container process that is a process on the containers. In the container process, the processor performs processes of determining the number of the containers, the types of the containers, the positions of the containers, and items to be assigned to the containers according to given selection conditions.

Abstract: An internal grinding machine having two grinding wheel spindles each of which has a grinding wheel for grinding a part of the inner or end surfaces of a workpiece. The workpiece is ground by both the wheels while it is held in a work spindle. The machine includes a wheel carrier assembly comprising a first wheel carrier table slidable in a direction on the machine base and being provided with a dressing infeed mechanism and an infeeding mechanism for the wheel spindle which is to grind the taper or face of the workpiece, and a second wheel carrier table slidable in a proper direction on the first wheel carrier table and having the grinding wheel spindles adjustably mounted thereon. The machine further includes a shift-infeed table having the work spindle thereon. The shift infeed is provided with a dressing infeed mechanism and an infeeding mechanism for the other wheel spindle.

Abstract: Infeeding method for internal grinders has rough grinding infeeding and fine grinding infeeding speeds. The changing point from the rough grinding to the fine grinding is shifted earlier in response to the grinding wheel diameter decreasing so that the actual stock-removal rate and the work-up time for a workpiece are kept approximately constant with uniform working on the workpiece.
