    Abstract: A semiconductor integrated circuit for controlling the substrate potential is disclosed, in which a substrate potential generating circuit is connected to a substrate and can be operated on at least a certain operation voltage level to generate the substrate potential. A detection circuit outputs a first detection signal upon detecting that the substrate potential has become lower than the operation voltage level by more than a preset amount, and outputs a second signal upon detecting that the substrate potential has reached a preset level which is slightly lower than the operation voltage level. A charging circuit charges the substrate upon receiving the first detection signal and interrupts the operation of charging the substrate upon receiving the second detection signal.

    Abstract: An apparatus for controlling an operating stroke of a reciprocating member to be reciprocated by a drive motor. The apparatus includes an encoder adapted to generate pulses each of which corresponds to a predetermined incremental distance of movement of the reciprocating member, a counter for counting the pulses during movement of the reciprocating member in a forward direction, a device for converting the operating stroke into the number of the pulses corresponding to a multiple of the incremental distance of movement, and a residual distance which is a difference between the operating stroke and the multiple, a device for converting the residual distance into a corresponding residual time, and a device for commanding the drive motor to stop an operation thereof causing a further forward movement of the reciprocating member, when the residual time has elapsed after a count of the counter is equal to the above-indicated number of the pulses.
