In a gas combustion type fastener driving machine, a fuel gas and air are stirred by a fan within a combustion chamber, a stirred air-fuel gas mixture is burned by an ignition spark, and a striking piston is actuated by a combustion pressure to drive a fastening member. The machine is provided with a fan motor (320) for rotating the fan, and a control circuit board (100) for controlling an action of the fan motor (320). The control circuit board (100) detects an actuation signal for an igniter (310) that generates the ignition spark and controls a rotation speed of the fan motor (320) based on the actuation signal.

To provide a media determining apparatus for enabling transparency of a medium to be determined at low cost, the media determining apparatus is provided with a transport section that transports a medium, a sensor including a light emitting device and a light receiving device to detect the medium, and a control section that detects the medium transported with the transport section corresponding to an output voltage of the sensor. The control section determines transparency of the medium by comparing the output voltage A of the sensor before a front end of the medium arrives at a detection position of the sensor, the output voltage B of the sensor when the front end arrives at the detection position, and the output voltage C of the sensor after the front end arriving at the detection position.

A fuel cell stack includes a stack of fuel cells. Each of the fuel cells includes a membrane electrode assembly and a separator that are stacked. The membrane electrode assembly includes an electrolyte membrane and a pair of electrodes sandwiching the electrolyte membrane therebetween. The terminal plate, the insulation plate, and the end plate are stacked at each end of the stack of the fuel cells in a stacking direction of the fuel cells. The terminal plate has a plurality of spaces formed therein. The spaces are separated from each other by a partition wall. A connection terminal is disposed on a plate surface of the terminal plate. The plate surface faces the insulation plate, at a position at which the connection terminal does not overlap the partition wall in the stacking direction. The connection terminal protrudes outward from the end plate in the stacking direction.

A game system acquires an input image from an input section that applies light to a body and receives reflected light from the body. The game system controls the size of an object in a virtual space based on a distance between the input section and the body, the distance being determined based on the input image. The game system generates a display image including the object.
