Title: Power system automatic recovering device
Inventor: YUKI MASARU
IPC: H02J3/00
Filed: 1990-05-15
Abstract: PURPOSE:To prevent erroneous control and to improve reliability by imparting a fail safe to open/close command output to a breaker. CONSTITUTION:Since the normal open contact 33-2 of an auxiliary relay is not operated if an open command 29 of a breaker is operated by an erroneous operation of a calculation processor 102 or an input/output processor 101 when a recovery start command is not received, an erroneous control output to a control coil 30 of a breaker is prevented. An erroneous output of a closing command to a normal open breaker is prevented similarly to the above by the normal open contact of the auxiliary relay to be operated at the time of reception of a recovery command to the closing control of the normal open breaker at the time of reception of the recovery command. That is, when an open command is output to a receiving side CB under one condition that a recovery start command is received, the normal open contact of the auxiliary relay to be operated by the start command reception is operated as a fail safe. When a close command of the normal open breaker is output under one condition that the recovery command is received, the normal contact of the auxiliary relay is operated as a fail safe.

Abstract: PURPOSE:To prevent a ground stain and to easily execute an image adjustment by adjusting the supply voltage of an original lamp in accordance with the degree of fatigue of a photosensitive body, and correcting automatically a developing bias potential, when the supply voltage reaches a prescribed value. CONSTITUTION:Even when the supply voltage of an original lamp of F5 is 69V at the time point of copying of 20,000 sheets, a bright part potential VL value becomes -200V. In such case, when a user adjusts an F5 shift key 10 again, an adjusting means, first of all, raises the original lamp supply voltage to 69V of a prescribed value by a lamp regulator 13, and switches it automatically to a developing bias DC portion by a microcomputer 15.

Accordingly, the original lamp supply voltage becomes 69V of the upper limit, and -250V adding -30V to -220V of the initial developing bias DC portion is applied to a developing sleeve 32. In such way, a correct image being free from fog is obtained.
