Abstract: A light emitting apparatus emits light toward a real space in which a user wearing a head-mounted display is present. The light emitting apparatus includes a first light emitting unit that emits first light, which is used as a reference signal, a second light emitting unit that emits second light, which is used as a scanning signal that scans the real space at a timing based on the reference signal, and a controller that controls the first light emitting unit. The reference signal includes notification information to be submitted to the head-mounted display.

Abstract: An electrical apparatus includes a rectifier circuit arranged to rectify a commercial supply voltage; a microcomputer including an input port to which a voltage obtained by subjecting an output voltage of the rectifier circuit to voltage division is inputted, an output port arranged to output an output signal to drive a direct-current load, an A/D conversion portion arranged to convert the voltage inputted to the input port to a digital signal, and a control portion arranged to determine a voltage of a commercial power supply based on an output from the A/D conversion portion, and generate a drive signal for optimum control of the direct-current load in accordance with the voltage; and a driver circuit portion arranged to drive the direct-current load based on the drive signal outputted from the microcomputer.

Abstract: A fuel cut control system for an internal combustion engine is arranged to generate a fuel cut command when a predetermined engine operating condition is satisfied, to start a fuel cut of stopping a fuel supply to engine when a delay time elapses from a moment at which the fuel cut command is generated, and to shorten the delay time when the fuel cut command is generated during a downshift of a transmission drivingly connected with the engine.

Abstract: Disclosed is a method for controlling track jumps of an optical pickup in gaining high-speed access to a target track freeing from any effects of disturbances, in which time intervals of a TZC (tracking zero cross) signal are measured continuously for comparison between a target time and a measured time required for a track jump by the optical pickup. The difference in time is computed as an error, and a control signal with a voltage or a pulse width reflecting the magnitude of the error is output to an actuator of the optical pickup. In controlling the driving speed of the actuator, the comparison between target and measured times takes into account not only a time difference regarding the preceding track but also time differences with respect to a number of the previous track jumps.
