IPC: F16K31/06
Filed: 2000-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a driver circuit capable of properly driving a plurality of kinds of solenoids. SOLUTION: In the solenoid driver circuit 12, the magnitudes of voltage corresponding to a signal Sduty from a micro computer 10 and a triangular wave from a triangular-wave generating circuit 32 are compared by a comparator 34, and a duty driving signal is transmitted to a gate for an FET 22 for conducting electricity through a solenoid from the comparator 34. Constant voltage Vts is input to the comparator 34 in the case of a high test signal Stest from the micro computer 10, and a driving signal in constant frequency at a constant duty ratio is transmitted to the FET 22.  Whether or not the solenoid 1 is either of two kinds is discriminated according to whether or not an average current flowing through the solenoid L to be driven reaches a fixed value or more in this case, and the result of the discrimination is stored in a flip-flop 56 in the case of the fall of the test signal Stest. Thus, the output frequency of the triangular-wave generating circuit 32 in a normal case and an overcurrent decision level in an overcurrent detector 36 are set in response to the stored result.

Title: Roll gap controller of shaking husking separator
Inventor: MATSUMOTO TOSHIYUKI
IPC: B02B7/00
Filed: 2000-05-31
Abstract: PROBLEM TO BE SOLVED: To return grains in a prescribed hulled ratio to husking rolls from a shaking separation plate of a shaking husking machine. SOLUTION: The boundary between a paddy layer near a paddy partition plate 19 on a minus sieve side 15d of the shaking separation plate 15 and a mixed rice layer is detected by a paddy sensor 48. The detection boundary value of the paddy sensor 48 and a reference boundary value are then compared and if the detection boundary value is higher than the reference boundary value and the hulled ratio of the returned grains is low, the roll gap of the husking rolls 7 and 7 is adjusted to be closed. When the detection boundary value is lower than the reference boundary value and the hulled ratio of the returned grains is high, the roll gap of the husking rolls 7 and 7 is adjusted to open. The roll gap of the husking rolls 7 and 7 is thus controlled associatively so as to reset the detection boundary value of the paddy sensor 48 to the reference boundary value.  Even if the hulled ratio of the husking rolls 7 and 7 is changed by the differences in the moisture of the grains and the differences in their variety, the grains of the prescribed hulled ratio may be returned from the shaking separation plate 15 to the husking rolls 7 and 7 and while the damage by two times of husking of the unpolished rice is prevented, husking work may be efficiently carried out.
