Title: Demodulation circuit for digital phase modulated wave
Inventor: YABE KAZUHISA
IPC: H04L27/233
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To provide a demodulation circuit remarkably lowering the frequency of a phase modulated wave without causing remarkable deterioration in demodulating precision while keeping a demodulating system as it is. SOLUTION: A relative phase data detecting part 4A counts a reference clock and outputs the counted value of the reference clock in rising of a rectangular wave from a limiter 1 as relative phase data. An interpolation circuit 7, based on its present relative phase data and relative phase data just before, obtains necessary relative phase data which is short in a period from a time just before to the present time and outputs it. A phase data selecting circuit 8 detects shifting from the rising edge of a symbol clock to the rising edge of a rectangular wave just after it and selects relative phase data outputted from the circuit 7 according to this shifting.

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of leaving operation by beforehand setting rules regarding the cooperative treatment of carrier trucks, load distribution to other stages, the allocation of the carrier trucks and the shift of parking chambers.

Abstract: PURPOSE: To obtain a high-resolution electronic balance by making a pulse current from a pulse current generating section to flow to a coil together with a pulse current which is obtained by changing peak value of a pulse current from another pulse current generating section and compensating the limit of the duty resolution of the balance. CONSTITUTION: The output of a displacement sensor 5 is inputted to a PID calculating section 13 through a displacement detecting circuit 11 and A/D converter 12 and the calculating section 13 decides the feeding back value of, for example, 24 bits to a coil 3 at every displacement data. Input data of 17 high-order bits and 7 low-order bits are respectively inputted to pulse current generating sections 14 and 15 in addition to clocks for feedback and for duty. The generating section 14 makes a pulse current having a fixed peak value and duty proportional to the input data to flow to the coil 3 in a fixed period and, when the supply of the pulse current to the coil 3 is completed, makes another pulse current having a duty which is made constant against a clock period for duty and a peak value proportional to the input data to flow to the coil 3.  Therefore, the resultant current of the coil 3 is changed in accordance with the fed-back value and comes to have 24-bit resolution.
