  • Patent number: 11916164
    Abstract: A method for manufacturing a light-emitting element includes providing the light-emitting element that includes a light-emitting layer with an emission wavelength of not more than 306 nm and a p-type layer including AlGaInN including Mg as an acceptor, and removing hydrogen in the p-type layer from the light-emitting element by irradiating the light-emitting element with ultraviolet light at a wavelength of not more than 306 nm from outside and treating the light-emitting element with heat in a state in which a reverse voltage, or a forward voltage lower than a threshold voltage of the light-emitting element, or no voltage is applied to the light-emitting element. The removing of hydrogen in the p-type layer from the light-emitting element is performed in a N2 atmosphere at not less than 650° C. or in a N2+O2 atmosphere at not less than 500° C.

  • Patent number: 11222634
    Abstract: It is an object of the present invention to induce a dialogue to a topic that a dialogue system tries to present. A dialogue system 100 presents a first utterance which is a certain utterance and a target utterance related to the first utterance to a user 101. A humanoid robot 50-1 presents the first utterance. A microphone 11-1 receives a user utterance of the user 101 after the first utterance. A humanoid robot 50-2 presents at least one topic-inducing utterance for inducing the topic to the target utterance based on a recognition result of the user utterance and an utterance sentence of the target utterance after the user utterance.
