Title: Digital data transfer system
Inventor: ASO MINORU
IPC: H04L7/04
Filed: 1989-02-17
Abstract: PURPOSE:To simultaneously transfer the data of (n) bits by using one data transfer line and to attain fast data transfer with the small number of transmission lines by converting the digital data of the (n) bits to the voltage level data of 2<n> stages corresponding to these digital data. CONSTITUTION:The digital of the (n) bits sent from an output side block 1 are converted to the voltage level data of the 2<n> stages corresponding to these digital data with a D/A converter 3 provided on the output side of the digital data and these voltage level data are sent to an A/D converter 4 in an input side by passing the data through one data transfer line 5. In the A/D converter 4, the sent voltage level data of the 2<n> stages are converted to the digital data of the (n) bits corresponding to these voltage level data and after that, the data are supplied to an input side block 2. A timing control line 6 is used when the transfer is executed by time division since the quantity of the data to be transferred is much. Then, since a voltage level is successively switched at every (n) bits in the transfer data and the data are sent, a lot of data are transferred.

Title: Feed driving device
Inventor: TOKAWA TAKAHIDE
IPC: G05B19/18
Filed: 1991-03-06
Abstract: PURPOSE:To precisely correct a pitch error even in a high speed movement state by controlling the read timing of the stored corrected value based on moving speed of a moved object. CONSTITUTION:A read controller 14 is added between a present value counter 9 and a storage 10, and the corrected value is read out of the storage 10 in the timing accordant with the moving speed of a moved object 8. At the same time, a speed detector 13 obtains an average speed of the object 8 based on the command pulse received from a numerical command device 1. In other words, the controller 14 calculates a time delay during which the pitch error correction data are reflected from the average speed of the object. This time delay is added to the value of the counter 9 after calculation of the offset value of the position where the time delay is canceled. Based on this addition result, the corrected variable data that are read out of the storage 10 are selected and outputted to an addition/subtraction counter 12.

Abstract: PURPOSE:To make it possible to put a counter circuit into operation at a high frequency all the time without reference to the state of a program by dividing the counter circuit into a front stage and back state and then by setting a FF circuit when the preset condition of the back-stage counter is detected. CONSTITUTION:This counter is divided into front stage 52 and back stage 53, and the output of FF55 set by preset condition detection part 54 of back stage 53 and reset by the output of preset signal generating part 57 of front stage 52 is supplied as an input to preset condition detection part 56 of the front stage and as a preset signal for back stage 53. In this constitution, since a signal inhibiting the operation of detection part 56 is the output of FF55 reset by a preset signal outputted from generating part 57, setting the propagation delay time of the signal of FF55 sufficiently small prevents malfunction even if the number of bits of the counter would be great, putting the counter into operation at a high frequncy all the time without reference to the state of the program.
