    Abstract: The present invention provides means capable of imparting high temporal stability to a hardening aid solution which serves as a raw material and capable of imparting high strength and high quality stability to a hardened body of the self-hardening material, in the hardened body of the self-hardening material that contains a ceramic powder containing Si element at least on the surface thereof. The present invention relates to a hardening aid solution containing Si element, an alkali, and a dispersing medium, wherein the dispersing medium contains water; a dissolution concentration of the Si element is 20000 mass ppm or more; the number of moles of the alkali present in 1 kg of the dispersing medium is 2 mol/kg or more; an absolute value of an amount of change in a dissolution concentration of Si element in a solution obtained by diluting the hardening aid solution by 2 times based on the mass using an aqueous KOH solution having a concentration of 3 mol/L is 2000 mass ppm or less, between before and after a heat dissolution test including heating the solution at a solution temperature of 80° C. for 5 hours, and then allowing the solution to stand in an ambient environment at 25° C. for 1 hour; and the hardening aid solution is used for hardening a powder containing a ceramic powder containing Si element at least on the surface thereof.

    Abstract: A learning system for performing reinforcement learning of a cooperative action by agents includes the agents; and a reward granting unit configured to grant a reward. The reward granting unit performs a step of, in the presence of a target agent to which the reward is to be granted, calculating an evaluation value relating to a cooperative action of other agents as a first evaluation value; a step of, in the absence of the target agent, calculating an evaluation value relating to a cooperative action of the other agents as a second evaluation value; and a step of calculating a difference between the first and second evaluation values as a penalty of the target agent and calculating the reward to be granted to the target agent based on the penalty. The target agent performs learning of the decision-making model based on the reward granted.

    Abstract: A tool holder attached to a main spindle of a machine tool is provided. The tool holder includes a main body that has a tubular shape and extends in a direction away from the main spindle with the tool holder attached to the main spindle; an optically pumped laser that is installed inside the main body and configured to radiate a laser light by using an exciting light provided by a light source; an optical system that guides the laser light radiated by the optically pumped laser so that the laser light is emitted from a leading end of the main body in an extending direction of the main body; and a light-guiding path that guides the exciting light from an outside of the main body to the optically pumped laser.
