摘要:
An operation input reception unit (201) receives an operation input for a virtual vehicle. A running condition managing unit (203) manages the running conditions of the virtual vehicle based on the received operation input. An acceleration calculation unit (205) calculates an acceleration in a front or back direction caused by an inertia force in a case where a managed running condition is acceleration/deceleration, and calculates an acceleration in the left or right direction caused by a centrifugal force in a case where a managed running condition is turning. A meter producing unit (206) produces a meter image showing the direction and level of acceleration based on the acceleration calculated by the acceleration calculation unit (205). A display control unit (207) synthesizes a view field image produced by an image producing unit (204) and the meter image produced by the meter producing unit (206), and displays the image on an external monitor or the like.

In a game device (301) for showing a past operation history to a player in comparison with the current operation status, a first moving unit (303) moves a first object in a virtual space based on a moving instruction input received by an input receiving unit (302), an input history storage unit (304) stores the moving instruction input as input history information, a second moving unit (305) moves a second object in the virtual space based on input history information stored in the past, an assessment unit (306) assesses whether or not the first object and the second object are overlapping in the virtual space, and a display unit (307) displays the second object in a case where a non-overlapping state has been identified and stops the display of the second object in a case where an overlapping state has been identified.

A power conversion device includes a printed circuit board, whose mounting surface is opposite to an annular surface formed by an annular stator that constitutes a motor, arranged to be separated from the annular surface with a predetermined distance, and mounted with a Hall element that detects a rotation position of a rotor of the motor on a mounting surface on a side of the stator; an inverter IC that is mounted on the mounting surface on the side of the stator of the printed circuit board to supply a high-frequency current to the stator; and an overheat detection unit that is mounted on the mounting surface on the side of the stator of the printed circuit board and detects an overheated state of the inverter IC. When the overheat detection unit detects an overheated state, the inverter IC restricts or stops a current to be supplied to the stator.

A drive device driving a power converter that includes a switching element formed from a wide bandgap semiconductor, includes a PWM-signal output unit that generates a drive signal that drives the switching element with PWM; an on-speed reducing unit that, when the switching element is changed from off to on, reduces a change rate of the drive signal; and an off-speed improving unit that, when the switching element is changed from on to off, draws charge from the switching element at a high speed and with a charge drawing performance higher than that at a time when the switching element is changed from off to on.

Disclosed is an evacuated and unevacuated microcellular foam containing an infrared attenuating agent (IAA). The evacuated foam has an average cell size of about 70 micrometers or less. The unevacuated foam has an average cell size of 1.0 micrometers or less. The IAA provide a greater proportional reduction in foam thermal conductivity in these foams than in foams of larger cell size. Further disclosed is a method of using the foams.

An electric leakage preventive apparatus comprises an equivalent impedance which is equivalent to a load leakage impedance of a load in a main body; a switching unit for applying voltage to the equivalent impedance; a driving unit for driving the switching unit; and a control unit for generating a switching pattern. The leakage preventive apparatus is capable of simply and surely preventing leakage current since the earthing current is canceled by applying an anti-phase voltage to the equivalent impedance.
