Abstract: The control unit executes an irradiation plan acquisition step and a spot interval guide display step. At the irradiation plan acquisition step, the control unit acquires an irradiation plan for irradiating a patient's eye with treatment laser light using a contact lens having a reflective surface that reflects the treatment laser light in a direction intersecting the optical axis. At the spot interval guide display step, the control unit controls the internal display unit to display a spot interval guide indicative of an appropriate interval between a plurality of irradiation spots in accordance with the progress of the irradiation plan. The plurality of irradiation spots are scheduled to be irradiated with the laser light.

Abstract: A method of controlling idle of an internal combustion engine including a variable vibro-isolating supporting device for actualizing vibro-isolating characteristics corresponding to a variety of vibrations, comprises a step of increasing a frequency of idle vibrations by increasing the number of idling rotations of the internal combustion engine by a predetermined number of rotations under a suing environment where a desired vibro-isolating effect is not obtained by the variable vibro-isolating supporting device, thereby preventing the idle vibrations from being transmitted to a car body side of an automobile etc.

Abstract: In an internal combustion engine to which an air pressure actuation mechanism such as a variable vibration isolating support device is installed side by side, the engine speed at the time of idling is made to suitably converge on the target idling speed.
