Title: Electrophotographic device
Inventor: UNO MUGIJIROU
IPC: G03G15/02
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To suppress a white spot-like abnormal image from being caused on a half-tone image by preventing an electrifying brush roller from being soiled with time by pulverized toner or toner additive, for example, silica being easy to get through a cleaning blade because the grain diameter thereof is small. SOLUTION: Before an image forming process is shifted to the next image forming process after a series of image forming processes is finished, the supply action of voltage to the electrifying brush roller 2 is stopped as long as time required for rotating the roller 2 one or more times. Then, the next image forming process is started after prescribed time elapses. As the result, electrostatic force by which particulates are attracted to the brush of the roller 2 is eliminated. When the roller 2 is rotated one or more times on this condition, the particulates attached to the roller 2 is mechanically scraped while the roller 2 is brought into contact with a photoreceptor 1.

Title: D/a converter test device and semiconductor test device using the test device
Inventor: IIDA YOSUKE
IPC: G01R31/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To obtain the D/A converter test device with a high throughput by conducting a comparison test between a reference D/A converter and a tested D/A converter. SOLUTION: A differential amplifier 70 is a differential amplifier with a high gain amplification, a gain error, an offset error or presence of glitch or the like with magnification resulting from the comparison between a reference D/A converter 60 an a tested D/A converter is outputted. Then a dual comparator 80 is a dual comparator consisting of a comparator 81 for an upper limit comparison and of a comparator 82 for a lower limit comparison. When an output voltage of the amplifier 70 exceeds the upper limit, the comparator 81 provides an output of a voltage or when an output voltage of the amplifier 70 is less than the lower limit, the comparator 82 provides an output of a voltage. In this case, the tested D/A converter is discriminated to be a defective D/A converter.  In other cases, when the output voltage of the amplifier 70 is within the range between the upper limit and the lower limit, the tested D/A converter is discriminated to be a non-defective D/A converter. Since the time to require testing the tested D/A converter is faster than that by a conventional test, the test with a high throughput is conducted.

The soot washing by the instant device is performed in such a manner that the  changeover valve 7 is opened while the boiler is stopped and the soot adhered to the  surface of the feed water preheating pipe 3 at the time of preheating the feed water is  washed by injecting from the boiler blow-water injecting pipe 6 the boiler blow-water  flowing in the reverse direction due to the pressure in the boiler. In this case, the heat  transfer surface of the pipe 3 is neutralized and the resultant drain is discharged from  a drain pipe 8. Consequently, the flash of steam does not flow backward into the combustion device since the boiler blow-water is cooled by the preheating pipe 3.
