Title: Electrostatic latent image forming device
Inventor: UEDA JUNKO
IPC: G03G15/00
Filed: 1990-03-23
Abstract: PURPOSE:To improve gradation in the high light part of an output image by using an electrostatic charger provided with a surface potential regulating member where an AC voltage is superposed as a 2nd electrostatic charging means after image exposure is performed after a photosensitive body passes a 1st electrostatic charging means. CONSTITUTION:After the photosensitive body 15 passes the 1st electrostatic charging means 11, the surface of the photosensitive body 15 where a potential is lowered because the image exposure is performed there is regulated by 2nd electrostatic charging which is performed by using the electrostatic charger 13 provided with the surface potential regulating member where the AC voltage is superposed as the 2nd electrostatic charging means after the image exposure 12 is performed. Thus, gamma correction for maintaining the gradation of the high light part of the output image is facilitated by making laser output and surface potential a proportional function, and the stability of output gamma is improved in the change of the sensitivity characteristic of the photosensitive body.

Title: Range finder
Inventor: KUBO KAZUHIRO
IPC: G01S17/93
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To obtain a range finder which prevents a situation that an object existing at a long distance is hidden so as to be incapable of being recognized because the image of an object which exists at a short distance and whose quantity of reflected light is large is spread transversely so as to be recognized. SOLUTION: A delay-time measuring part 32 measures a delay time-up to a light-receiving signal (c) from a light-emitting signal (a), and a distance comporting part 33 computes a distance up to an object on the basis of the delay time. A light-receiving-level level detection part 30 extracts a signal at a light-receiving level designated by a light-receiving-level-designation changeover part 31, and the signal is sent to the delay-time measuring part 32. Since the light-receiving level of the light-receiving signal designated by the light-receiving- level-designation changeover part 31 is changed over at a constant cycle, a light-receiving signal which is different at every contact cycle is extracted as a signal for delay-time measurement.
