摘要： In a misfire detector device for use in internal combustion engine, an electrical interrupter circuit on-off actuates a primary current flowing through a primary circuit of an ignition coil to induce a spark plug voltage. A check diode is provided in a secondary circuit of the ignition coil to prevent a current flowing back to the ignition coil. The spark plug has a center electrode, a front end of which is projected from an insulator, and an outer surface area of the projected front end being 25 mm.sup.2 or more. A spark plug voltage detector circuit detects an attenuation time length of a spark plug voltage waveform presented subsequent to a predetermined time period occurring after an end of a spark action of the spark plug. On the basis of the attenuation time length, a distinction circuit determines whether a misfire occurs in a cylinder of an internal combustion engine.

摘要： A detector device for determining the mixing ratio of gasoline and alcohol includes a flint glass plate, one side of which is placed to be in direct contact with a mixing liquid of gasoline and alcohol, a light emitting diode is located at the other side of the flint glass plate to be opposite to the mixing liquid so that light beams emitted from the diode enter the flint glass plate to be incident on a boundary between the plate and the mixing liquid and a photo diode having a rectangular shape and located in coplanar relationship with the light emitting diode to receive the light beams totally reflected from the boundary. The distance between the photo diode and the light emitting diode and the width dimension of the photo diode are determined such to provide incident angles ranging from a minimum corresponding to the critical angle when the mixing liquid ratio is at lower limit of the predetermined range to a maximum corresponding to the critical angle when the mixing liquid ratio is at upper limit of the predetermined range.
