Abstract: A head controller 2 reads out adjustment data from a ROM 3 immediately after a power-on operation. The adjustment data is prepared for adjusting unevenness of light emission from LEDs in a LED head 5. A buffer memory 4 stores the read adjustment data. The head controller 2 reads the adjustment data from the buffer memory 4 with high data transfer rate, and obtains bitmap data from a frame memory or the like (not shown). The head controller 2 sends the read bitmap data and the adjustment data to an anode driver 51. The head controller 2 sends a strobe signal to the anode driver 51 and a cathode driver 53. The anode driver 51 adjusts ampere of supplied currents (i.e. drive signals corresponding to the bitmap data) from the head controller 2, in accordance with the received adjustment data in response to the reception of the strobe signal. The adjusted drive signals are sent to LED array chips 52.

Abstract: A floppy disk in which the binder for fixing a magnetic substance in the recording layer of the magnetic disk is a polyester polyurethane and the liner of the jacket contains an acrylic fiber and in addition a fiber treating agent having a surface tension in a specific range. The floppy disk is excellent in workability, can be prepared in high yields because the number of dusts generated upon its preparation is small, and also is excellent in the permanence of recording performance.

Abstract: An image forming apparatus comprises a thermal fixing apparatus having a heat generating member and heat-fixing an image on paper, a section for discriminating a using frequency of the image forming apparatus, and a section for controlling a fixing temperature having a first temperature control mode maintaining the temperature of the thermal fixing apparatus to be a first temperature at which the image can be fixed, a second temperature control mode maintaining the temperature of the thermal fixing apparatus to be a second temperature, which is lower than the first temperature by a predetermined temperature, and a third temperature control mode stopping current supply to a heat generating member of the thermal fixing apparatus.

Abstract: Process and apparatus for automatically attaching a ferrule to each end of a cable such as an optical fiber cable are proposed. The cable is cut into suitable lengths and coiled for easy handling. All the steps are done automatically and the stripping and subsequent steps are done while the coiled cable loop laid down on a conveyor rack is conveyed intermittently from one station to another.

Abstract: In a counter apparatus for an image forming apparatus according to the present invention, which counts and manages the number of image forming operations, data which is ultimately written is retrieved from data stored in an EEPROM, and the retrieved data is set in a RAM counter as an initial value. The RAM counter performs a count-up operation for each printing operation for production of new data. The new data is written in the EEPROM for each production, so that a count value when a power source is turned off is held therein. In the EEPROM, a plurality of unit areas are continuously provided and are used as data write areas. The new data is sequentially written for each unit area. Thus, the number of write operations for the unit areas is decreased, so that the EEPROM which has a limited number of times of write access can constitute the counter apparatus together with the RAM counter.
