Abstract: A base station device includes: a detection unit that detects approach of a mobile station device; a determination unit that determines whether or not the detected mobile station device is an unmanned aircraft; and a notification unit that notifies of the approach of the mobile station device in a case that it is determined that the mobile station device is an unmanned aircraft.

Abstract: The present invention is characterized in that a time elapsed since activation can be retained even after a time timer is updated to time information externally acquired, by updating a value in the time timer that starts count-up after activation with the time information externally acquired, and by subtracting a value of the time timer from the acquired time information and reflecting this subtracted value into a reference time storage part.

Abstract: Blocks and inner rings of rolling bearings are arranged on the outer surface of a hollow shaft at predetermined intervals in the axial direction thereof. The outer surface of the hollow shaft is plastically deformed in its diameter enlarging direction so as to be press-fit to the inner surface of the blocks and inner surface of the inner rings of the rolling bearings. In this state, the blocks and inner rings of the rolling bearings are fixed to the outer surface of the hollow shaft.

Abstract: In order to automatically activate a debugger while maintaining the status of the machine as it was just before execution of the instruction which has raised an exception even in a case in which a break point is not set beforehand, a computer, which executes a program to be debugged, analyzes an exception raised on the computer, and replaces an instruction with another instruction for activating a debugger if the exception has been raised due to the instruction that conducts an abnormal operation and is stored in a memory space. After this, the computer selects and switches to a task to be processed based on the status of each of the tasks, or resumes an operation which has been suspended due to the exception. Then, when the computer executes the instruction for activating the debugger, the debugger detects this execution and is activated.

Abstract: A power steering apparatus including an electric motor for operating a hydraulic pump which supplies pressurized fluid, a directional control valve of center-closed type operable by a steering wheel for delivering the pressurized fluid supplied by the hydraulic pump selectively to a pair of cylinder chambers of a power cylinder through a supply passage, and motor controller for controlling the electric motor. While the steering wheel is at its neutral position, the controller drives the electric motor intermittently at such a low speed that does not deteriorate the efficiency of said electric motor so much so that differential pressure between a pressure at the supply passage and a higher one of pressures in the pair of cylinder chambers is returned to a predetermined first value.
