Abstract: The present invention relates to a dementia test system and the like for testing a dementia degree of a testee, and provides a dementia test system which is effective for preventing and finding, at early stage, an initial sign (initial dementia) of senile dementia.

Abstract: A computer solves an item-based one-dimensional sub-optimization problem independently of the other items. For the item-based solution found, the computer determines whether machine interference between the items is eliminated and whether a work-in-process inventory is sufficient. If machine interference is not eliminated or the work-in-process inventory is not insufficient, then the computer updates a corresponding Lagrange multiplier and reexecutes the solving of the problem.

Abstract: A device for heating a biotissue employing a strong light, characterized in that, in thermotherapy comprising leading a biotissue to necrosis by heating the biotissue by a strong light from a light source, in order to lead a predetermined biotissue to necrosis in a temperature region before reaching tissue transpiration during the raising of the temperature of said biotissue, temperature measurement is performed by a temperature meter measuring the spatial temperature distribution of the biotissue at real time, and that the light output of the light source, the on-time of intermittent irradiation and the off-time of intermittent irradiation are controlled on the basis of the information at real time to accomplish remedial conditions.

Abstract: Disclosed is an optical memory head in which a vertical cavity surface emitting laser array constituted by laying out, in a matrix form, a large number of vertical cavity surface emitting laser elements each having a laser output part with an ultra fine hole as an output window for emitting evanescent light is arranged such that the layout direction of the laser element is inclined with respect to the tangential direction to rotation of an optical recording medium at a fine angle.

Abstract: A method for predicting a traffic flow rate at a point on a road to control a traffic light signaling system measures a traffic density on the road to predict a traffic flow rate by utilizing the fact that a velocity of a vehicle on the road is restricted by an interval between successive vehicles, since the traffic density is locally increased when the vehicle interval is not uniform and therefore the spatial mean speed is lowered. This method offers higher accuracy by utilizing a correction coefficient obtained from an actual vehicle distribution, for instance, a coefficient derived from entropy.
