摘要:
To enable a user to perform a hypothetical simulation of the use of firefighting equipment so as to be able to experience operation of such firefighting equipment without using actual firefighting equipment, a manual provision system includes an information terminal device, and a server in which manual information pertaining to an article is recorded, the information terminal device and the server connected to each other through a network, the manual information for the article being scanned into the information terminal device from the server through the network so as to allow the manual information to be checked using the information terminal device. The article is a piece of firefighting equipment and the manual information is a hypothetical operation simulation for the firefighting equipment so as to enable learning the manual information by using the information terminal device to operate the hypothetical operation simulation.
摘要:
A layer beam controller for an optical storage apparatus includes a laser beam generator, a laser beam power varier for varying the laser beam power to first, second, and third power levels, a memory for storing predetermined reference values including first reference values corresponding to the first power level and second reference values corresponding to the second power level, a light amount detector for detecting a light amount of the laser beam, a laser beam power corrector for correcting the laser beam power at the respective power level by comparing the light amount and a corresponding one of the predetermined reference values selected by a type of the compact disk in operation in the optical storage apparatus. The laser beam controller further includes a power level assigner for assigning the first, second and third power levels based on the type of disk.
