Abstract: An image forming apparatus has an image forming unit and a film-heat-type fuser over which a sheet with an unfixed toner image passes and on which are positioned a first temperature-measuring device centered on the fuser so that a sheet always passes over that device and a second temperature measuring device disposed away from the center so that large sheets will pass over the second temperature measuring device and small sheets will not pass over the device when being conveyed correctly. The device also has a temperature control mechanism, a sheet size detector and throughput control, so that the throughput control changes throughput when the sheet size detector determines that a small sheet is being conveyed and the difference between the temperatures of the first and second temperature measuring devices is less than a predetermined value as the sheet passes over the fuser.

Abstract: An installation structure allows easy installation of vibration-proofing members in an electric motor, which avoid resonance due to vibration of an engine, without increasing the number of components. A bottom wall of an installation hole for receiving the electric motor is spaced from a bottom wall of a yoke. Also, flexible tabs are formed on the bottom wall of the yoke. In this arrangement, the electric motor is installed in the installation hole in a manner such that the flexible tabs are pressed into contact with a step portion arranged on the bottom wall of the installation hole.

Abstract: An oxygen density detecting device for a combustor in which individual adjustment of reference levels for each combustor is not necessary. A memory device stores a reference ion current value from a sensor disposed in the combustor for a predetermined period of time extending from the time instant at which combustion breaks out in the combustor until the ion current has substantially stabilized. The oxygen density of the room air used by the combustor is determined by comparing the ion current value stored in the memory with ion current values which are successively provided by the sensing device. An output signal produced thereby is utilized to control circuit elements including a fuel supplying electromagnetic pump and a combustion air blower used for supplying room air into the combustor.
