An operation input reception unit (201) receives an operation input for a virtual vehicle to be run on the running path. Further, a running condition managing unit (203) manages a running condition of the virtual vehicle based on the received operation input. Meanwhile, a load calculation unit (205) calculates a load imposed on a virtual operator in the virtual vehicle based on the managed running condition. Further, a meter drawing unit (206) creates a meter image in which a head symbol is arranged within a circle. Specifically, the meter drawing unit (206) arranges the head symbol, which is moved according to the calculated load, from the center within the circle, in a corresponding direction by a corresponding distance. Then, a display control unit (207) displays the created meter image on a predetermined monitor.

A mounting structure of an electronic device capable of properly enhancing a bonding strength between an insulating substrate and the electronic device is provided. An electrode and an earth electrode having a surrounding shape are formed on an insulating substrate. In addition, a non-metal area exposing a surface of the insulating substrate is provided in the surrounding shape. An earth terminal is provided on a position opposed to the non-metal area on a back surface of an electronic device. The non-metal area and the earth terminal are bonded to each other by a solder adhesive including solder particles and a resin as major components. The solder particles are agglomerated on the earth terminal, then a solder layer is formed, and the earth terminal and the non-metal area are bonded to each other by the resin layer. Accordingly, a bonding strength between the electronic device and the insulating substrate are properly enhanced.

A reverse bias voltage is applied to a photodiode array provided with a plurality of avalanche photodiodes operated in Geiger mode and with quenching resistors connected in series to the respective avalanche photodiodes. Electric current is measured with change of the reverse bias voltage applied, and the reverse bias voltage at an inflection point in change of electric current measured is determined as a reference voltage. A voltage obtained by adding a predetermined value to the determined reference voltage is determined as a recommended operating voltage.
