Abstract: PURPOSE:To receive information transmitted from car to ground quickly with a central unit by outputting a poling signal preferentially to a terminal unit corresponding to a grounder on which a train has passed through, at time of this train passing. CONSTITUTION:After a train 1 has passed through a grounder 12A, when it is reached to another grounder 12B, ground information out of a central unit 20 being stored in a repeater 13B is taken into the car side, while car information out of the train 1 is stored in the repeater 13B via the grounder 12B. With the car information received, a train passing signal f1 is transmitted to the side of the central unit 20 from a train passing signal generating part 14B, and a train detecting signal is outputted to a terminal unit position judging part 24 from a passage detecting part 22. This terminal unit position judging part 24 reads terminal unit position information of a memory 23, and thereby it is so judged that a position, where the train 1 this time has passed through, is a terminal unit 11B, outputting it to a poling control part 25, and on the basis of the judged result, a sequence control signal of a poling signal is outputted to a central control part 21.

Title: Image forming device
Inventor: IMANISHI MASAHIRO
IPC: G03G15/16
Filed: 1990-07-25
Abstract: PURPOSE:To prevent the peeling of a transfer material supporting member and to prevent the generation of the jam of the transfer material by insufficiency of holding even in low-humidity environment by intensifying the attracting and holding of the transfer material at the time of non-transfer of a toner image onto the transfer material. CONSTITUTION:The attraction of the front end of the transfer paper P in the feed direction is merely required to be intensified in order to intensify the attracting and holding of the transfer paper P to a transfer drum 3. The transfer of the toner image on the photosensitive drum 1 to the transfer paper P does not arise, insofar as only the non-image forming area at the front end of the transfer paper P in the feed direction is electrified. Namely, the non-image forming area at the front end of the transfer paper P attracted and held on the transfer drum 3 is electrified by operating a transfer electrifier 4 usually in a range of 20mm at the front end to intensify the attracting and holding of the transfer paper P to the transfer drum 3. The transfer of the toner image on the drum 1 onto the transfer paper P attracted and held to the drum 3 is obviated in this way and the idling of the drum 3 is possible without peeling the transfer paper P from the drum at the time of non-transfer.

Title: Detecting device of amount of displacement
Inventor: MIBU KATSUTOSHI
IPC: G01D5/245
Filed: 1990-07-25
Abstract: PURPOSE:To obtain precisely and stably an origin signal corresponding to an absolute value of a scale division by obtaining the origin signal by correcting the position of the origin in accordance with a slippage of a phase between a reference signal (REF signal) and a lambda signal. CONSTITUTION:The title device has a slippage measuring means 8b which measures a phase slippage epsilonr and measurement-control means 8c and 8d which emit an output pulse corresponding to the amount of displacement until the measurement of this phase slippage epsilonr, add up this output pulse to the measured value of this slippage thereafter and take out the output pulse at the time when the measured value becomes a value corresponding to a recorded wavelength lambda of a scale 1a or a prescribed value, and the output pulse obtained by these measurement-control means 8c and 8d is taken as an origin signal. Since the origin signal is obtained by correcting the position of the origin in accordance with the slippage of the phase between a reference signal (REF signal) and a lambda signal, a phase slippage (error) of the origin signal does not occur even when an origin detecting speed is high, and thus the origin signal corresponding to an absolute position of a scale division can be obtained precisely and stably.
