IPC: G01D5/245
Filed: 1979-05-30
Abstract: PURPOSE: To perform the position detection without a multidigit encoder by computing the position by sampling outputs of an encoder the digit of which is not less than that of the increment of the maximum value of the movement of the object to be detected.  
     CONSTITUTION: When the maximum value of the movement is four increments or less during the sampling and the number of digits of the encoder is one and the present position at the time this sampling is finished is S n  and the value of the encoder in the sampling at this time is x n , the following formulas hold. Namely ΔS n =x n -x n-1 ...(1), when |ΔS n |≤4...(2), S n =S n-1 +ΔS n = S n-1 +x n -x n-1 ... (3), when ΔS n ≥6...(4), S n =S n-1 -(10-ΔS n )=S n-1 -[10- (x n -x n-1 )]...(5), when ΔS n ≤-6 ...(6), S n =S n-1 +(10+ΔS n )=S n-1 +[10+(x n -x n-1 ) ]...(7), S n-1 =S n ...(8), x n-1 =x n ...(9). Accordingly the present position can be obtained by computing the formulas (1)W(9) every time the sampling time is reached. When the maximum value of the movement of the object to be detected is 49 increments or less, the detection is performed by a two- digit encoder.

Abstract: PURPOSE: To suppress the processing load of a CPU at the time of a data transfer to a minimum. CONSTITUTION: At the time of the data transfer of an input equipment and a CPU, the number of the word of a data block when the data transfer with the input equipment is performed is preliminarily set by a CPU for a number of word of interruption register 2. The input equipment prepares data to be transferred to the CPU one by one, simultaneously transmits an I/O data writing signal and I/O writing data to a data storage part 1 and temporarily stores the data in the data storage part 1. Every time the data storage part 1 receives data one by one from the input equipment, the part 1 counts the number of data word. A number of word comparator 3 transmits an input interruption request signal to the CPU if the number of the data word received from the input equipment and stored becomes equal to the number of the word which is preliminarily set by the CPU.  Thus, the CPU reads the data blocks together by the interruption processing for every input request interruption.

Title: Magnetic tape device
Inventor: SUGIHARA MASAHIRO
IPC: G11B27/17
Filed: 1993-03-02
Abstract: PURPOSE:To make the detection of a travelled extent tape correct by recording marks periodically from the start edge of a magnetic tape and obtaining compesation values while comparing the travelled extent of tape to a mark detecting position with a travelled extent of tape based on a reel rotational speed. CONSTITUTION:Marks are recorded periodically on the magnetic tape by making the start edge of the tape to be a reference. When the first mark is detected, a compensation value deciding circuit 47 decides whether a tape feeding time Ta is an integral multiple of a period of the mark or not. At this time, the period of the mark is set to a value more than two times the maximum error in a tape running time detection. Then, the circuit 47 obtains a compensation value (t) by comparing an assumed travelled extent of tape to a position where the mark is detected with the detected value of the travelled extent of tape based on the rotational speed of the reel. When marks are detected succeeding the second mark, compensations are made in the same way. Thus, the tape length to a running tape position is known correctly by compensating a value indicating a tape length based on the mark detection.
