Title: Multiple rotation type absolute encoder
Inventor: TAMAE HIROAKI
IPC: G01D5/36
Filed: 1991-06-04
Abstract: PURPOSE:To enable the title encoder to detect an absolute position with high resolution and, at the same time, to reduce the size of the encoder and make the encoder compact by adding the count value of high-resolution incremental signals to the representative value of detected Z-phase values. CONSTITUTION:When an encoder is rotated by means of a motor and a reference signal Zn from an original signal outputting section 11 is detected by means of a process circuit 15, the value of a one-rotation absolute counter 16 changes from the representative value so far obtained to a value obtained by adding the count value of incremental signals to the representative value, namely, the representative value plus A-and B-phase count values. Thereafter, one-rotation absolute data are updated by using changes in A- and B-phases, matched to the valve of a multiple rotation counter 14, and transferred to a driver system through a conversion circuit 18. Since the absolute data change with high resolution of about 1/2,048, a commutation signal is changed to a sine wave signal and the motor is driven by sine wave drive on the driver system side. Therefore, the title encoder can be made compact.

<??>According to the invention the recovery of N-phenylmaleimide comprises the following successive stages: 
 
  (a) the reaction mixture is treated in a dilution and filtration zone in which it is diluted with an additional quantity of solvent, the dilute mixture being subjected to a low-temperature filtration in order to separate off a solid cake containing the catalyst and the impurities, and a filtrate consisting of a solution of N-phenylmaleimide in the solvent, and 
  (b) this solution of N-phenylmaleimide is subjected to a distillation at reduced pressure so as to separate off successively the solvent and N-phenylmaleimide of at least 99% purity, whereas the distillation residue is treated exactly as indicated in (a) above in a dilution and filtration zone for recovering the N-phenylmaleimide therefrom, the filtrate being returned to stage (a) to be used for diluting the reaction mixture for the synthesis which follows. 
 
<??>In addition, the filter cakes from stages (a) and (b) are washed with the solvent obtained by distillation in stage (b) and the washing solvents are recycled to the stage of synthesis of N-phenylmaleimide and/or to the dilution zones.
