Title: Image forming device
Inventor: ITAKURA HARUO
IPC: G03G15/20
Filed: 1990-05-12
Abstract: PURPOSE:To save power irrespective of ambient temperature by switching a fixing part to on/off control exerted at the fixed ratio at the time of a preheating mode. CONSTITUTION:In the preheating mode, a heater 43 is turned on/off at the fixed duty ratio. That is, assuming on-time and off-time are T1 and T2, respectively, the duty ratio is obtained by T1/(T1+T2). The higher the duty ratio is, the higher temperature and power ratio are. However, when the duty ratio is more than a certain value, little effect is produced, and even the power ratio is high, the temperature does not rise according to the power ratio. By determining the duty ratio, taking into account of such characteristics, the temperature of the heater in the preheating mode can be maintained at the prescribed temperature. Thus, power consumption becomes constant irrespective of ambient temperature, and the effect of saving power can be maintained.

Title: Error detector
Inventor: YOSHIDA EIJI
IPC: G06F11/00
Filed: 1984-06-14
Abstract: PURPOSE:To restore a system quickly when error occurs during the operation of a secondary storage device, by recording classifications and positions of errors which occur when data of a recording medium is read and checking this hysteresis. CONSTITUTION:When receiving a read instruction from a CPU1, a flopply disc controller 2 controls a foppy disc drive 3 to read out data on a floppy disc. If an error occurs, the CPU1 stores the position (a track number and a sector number) of this error occurrence on the recording medium and an error code in a RAM4. This position and the code error are compared with those of errors which occur in the past; and if the same kind of error occurs N-number of times continuously in the same position, it is judged that the recording medium is damaged physically or magnetically. The sector or the track where this error occurs is not used hereafter to stabilize the operation of an apparatus.
