Abstract: A photonic crystal surface-emitting laser includes a light emitting region from which light is emitted in a direction crossing an in-plane direction, and a current blocking region that is adjacent to the light emitting region in the in-plane direction and in which current is less likely to flow than in the light emitting region. The light emitting region and the current blocking region each include a photonic crystal layer. The photonic crystal layer has a first region and second regions periodically arranged in the first region. A refractive index of each of the second regions is different from that of the first region. The light emitting region includes a first semiconductor layer, an active layer, and a second semiconductor layer. The first semiconductor layer, the active layer, and the second semiconductor layer are sequentially stacked on top of one another in an emission direction of the light.

Abstract: An apparatus for predicting useful life of a photovoltaic module includes an input and an output. The input receives first information indicating an amount of hygrothermal stress that a photovoltaic module undergoes from a start until an end of a period during which the photovoltaic module outputs predetermined electric power. The input further receives second information indicating an amount of hygrothermal stress that the photovoltaic module undergoes per a predetermined time in a field where the photovoltaic module is deployed. The second information is generated based on information about daily maximum temperatures of the photovoltaic module in the field where the photovoltaic module is deployed. The output outputs result information about a predicted period during which the photovoltaic module is expected to output the predetermined electric power when the photovoltaic module is deployed in the field.

Abstract: A gas supplying system includes a processing gas supply pipe for supplying a processing gas from a gas cylinder 210 into a processing apparatus and a nonreactive gas supply source 230 for supplying a nonreactive gas into the gas supply pipe. While the system is in operation, the gas supply pipe is charged with the nonreactive gas and a control unit is in a standby state. If a processing gas use start signal is received from the processing apparatus, the system exhausts the nonreactive gas from the gas supply pipe to create a vacuum therein; charges the gas supply pipe with the processing gas; and starts a supply of the processing gas from the processing gas supply source. If a processing gas use finish signal is received from the processing apparatus, the system stops the supply of the processing gas from the processing gas supply source; exhausts the processing gas from the gas supply pipe to create a vacuum therein; and charges the gas supply pipe with the nonreactive gas.
