Abstract: PURPOSE:To enable externally control the resistance of an internal resistor in a semiconductor device by forming an oxidized film of varied thickness for each electrode of resistor on each electrode of resistor installed on plural resistors placed in parallel and forming an electrode for connection on the oxidized film. CONSTITUTION:Resistors 2-4 are placed in parallel and by connecting how many of these resistors 2-4, an expected resistance can be obtained. In order to connect the resistors 2-4, destruction of an oxidized film between an electrode 13 for connection and electrodes 9-11 of the resistors is used. Since voltage for the destruction is determined by the thickness of the oxidized film 12, number of the resistors to be connected can be decided by voltage applied to an external terminal connected to the electrode 13 for connection. That is, if the electrode 9 of the resistor 2 and the electrode 13 for connection are connected by the destruction of oxidized film, one resistor 2 is used and then if the electrode 10 of the resistor and the electrode 13 for connection are connected by increasing the applied voltage for destructing the oxidized film, the resistors 2, 3 are connected in parallel.

Abstract: PURPOSE:To enable write operation to be performed always from the same scan commencement position and avoid generation of color shift in the case of a color image by controlling the rotational amount of a photosensitive element drum with pulses generated each time a single line is scanned. CONSTITUTION:A photosensitive element drum is rotated once by multiplying an angle rotated at one pulse integer times. If a light shield 11B formed integrally with the photosensitive element drum is overlapped with a sensor 11A, a scan commencement position is detected by the sensor 11A, and if a laser beam is detected by a light detector 7, a pulse controlled motor 9 is rotated by single pulse. If the sensor 11A is induced, a signal is transmitted to a driver 14 through an output control circuit 12 and a gray scale processing circuit 13 to inform that a next line is a line a the tip of an image forming area. After receiving a next signal from a light detector 7, a latent image begins to be written. Thus the scan always begins to be performed starting with the same line on a photosensitive element drum 8 and the photosensitive element drum 8 is rotated by a single line on a next signal from the light detector 7 with the commencement of the scan on the second line.
