  • Power management method, power management server, and office machine for managing electric power
    Patent number: 9898023
    Abstract: According to one embodiment, there is provided a power management method for connecting a server to office machines to control electric power of the office machines. The office machines respectively store machine side power plans, which are operation states with respect to transition times. The server stores server side power plans of the office machines and subjects electric powers of the office machines to management control. The power management method includes comparing the server side power plan stored in the server and the machine side power plan stored in the office machines, comparing, when an operation state based on the server side power plan and an operation state based on the machine side power plan are different, power consumptions in the operation state based on the server side power plan and an operation state based on the machine side power plan, and changing an operation state of the office machine to be an operation state with small power consumption.

  • Output control method for laser system
    Patent number: 5369655
    Abstract: An output control method for a laser system comprised of a laser oscillator and a laser amplifier. The method enables the output energy to be stably controlled over a wide range, without changing the excitation energy, by controlling the delay (.tau.) of the excitation energy application timing of the laser oscillator with respect to the excitation energy application timing of the laser amplifier.
