    摘要: A machine managing apparatus (999) for concentratively managing conditions of a machine (100) and in particular an apparatus for monitoring an image-forming apparatus comprises communication control means (900), connected to an image-forming control means performing the control of an image-forming operation of a main body of the image-forming apparatus, for controlling transmission and reception performed via a communication line (908) to and from an external apparatus, and inhibit means for inhibiting the transmission from the communication control means to the external apparatus in order to prevent damaged data from being transmitted to the external apparatus, said damaged data being such that when a power supply of the image-forming control means is turned off during transfer of data from the image-forming control means to the communication control means, the data results in a loss.

    摘要: A driving method for a liquid crystal device of the type comprising a pair of oppositely disposed substrates each provided with an electrode, a chiral smectic liquid crystal disposed between the substrates to form a plurality of pixels and to be placed in a monostable state under no voltage application, and a plurality of active elements each of which is provided to an associated pixel and is connected with an associated electrode so as to effect a matrix drive of the liquid crystal device includes a step of driving the liquid crystal device so that the liquid crystal is tilted from the monostable state to provide a maximum tilt angle in actual drive smaller than a saturation tilt angle. The drive method is effective in suppressing burning or alignment state change of the chiral smectic liquid crystal, thus improving display characteristics.
