Title: Printer
Inventor: ITO YORIYASU
IPC: B41J21/00
Filed: 1989-03-31
Abstract: PURPOSE:To clarify that printing data requires two or more sheets of paper and to easily recognize the end of each sheet by applying a wave line processing or the like to printing data at the boundary part of an effective drawing area of a recording medium. CONSTITUTION:Character or symbol patterns developed on a bit map memory 104 are read by a main control part 105 and outputted to a printer engine 108 through a printer engine I/F part 107. Thereafter, with a printing start instruction outputted from the main control part 105, a drawing area for the printing data is checked, and whether it exceeds an effective drawing area for a sheet of printing paper is judged. If it exceeds, whether the printing data at the boundary part of the effective drawing area is applied with a wave line processing is determined, and the setting for printing is completed. After the processing mentioned above is finished, printing is started. In this manner, at the time of printing large size characters or data covering two or more sheet of recording medium, information with respect to the boundary line of the effective drawing area of the recording medium is shown in the printing data, whereby the joint parts of the printing data for each sheet is easily recognized.

Title: Electrophotographic method
Inventor: IRIHARA KOUICHI
IPC: G03G13/00
Filed: 1979-06-28
Abstract: PURPOSE: To obtain a fog-free copy of constant density by reducing uniform light illumination for rendering constant the trap state of electrons and holes of a photoreceptor immediately before copying in the electrophotographic method using a cadmium sulfide photoreceptor of 2 layer structure.  
     CONSTITUTION: In order to render constant the trap state of photoreceptor immediately before copying, a copying process comprises during one rotation of receptor 1 a pretreatment step for subjecting receptor 1 to negative polarity corona discharge from corona charger 2 and uniform light illumination as much as the light illumination on the light area at the exposure in a latent image forming step; a step for charging receptor 1 by negative polarity corona discharge of corona charger 2; a step for forming an electrostatic latent image; a toner image forming step; and an image transferring step. Increase of the uniform light illumination amount causes fog due to light fatigue on a copy, so it is necessary to reduce said amount, but in order to make the trap state constant, a light amount at least as much as that on the light area at the exposure in forming the latent image is necessary.

Abstract: PURPOSE:To dispense with the internal checkup of a device in accordance with a transport fault by enabling a jam cause interpreting device to interpret a cause for jam and a display device to display the result, if the cause for jam results from any other than the transport fault. CONSTITUTION:If a paper detection signal is not yet received from a sensor S1 even after the lapse of a specified time following the reception of the signal from the sensor S8.CPU interprets that a jam has generated on the paper feed path of a printing engine 3, and sends an appropriate command. A system controller 102 receives the command. Consequently, the system controller 102 sends an emergency stop command to each unit (for example, a perfect side unit 8, a reversal unit 5 or the printing engine 3). The LED of a jam indicator on a panel display 3a installed outside the printing engine 3 is switched ON and OFF through the engine in accordance with each command. Thus the operator is informed of the type of jam such as fixed, FD or DPX.

This combustion exhaust gas gets into a throttle pat 7 between the catalyst layers 6 on the upstream and in the middle to be mixed with the exhaust gas 11 distributed to the throttle part 7. This mixed gas gets into the catalyst layer 6 in the middle, where hydrogen in the exhaust gas 11 is burnt by oxygen in combustion exhaust gas. This combustion exhaust gas gets into the throttle part 7 between the catalyst layers 6 in the middle and on the downstream to be mixed with exhaust gas 11. This mixed gas gets into the catalyst layer 6 on the downstream, where hydrogen in the exhaust gas 11 is burnt by oxygen in combustion exhaust gas.
