Title: Method of measuring thickness of magnetic tape
Inventor: RAINHORUTO BAURU
IPC: G01B7/06
Filed: 1988-08-31
Abstract: PURPOSE: To measure the thickness of a magnetic tape while it is wound in roll by calculating the rotation per unit time of the hub while the magnetic tape is taken up, measuring the length of wound tape and calculating the tape thickness using a specified mathematical relational expression. CONSTITUTION: During winding of a magnetic tape, rotation per unit time nB of a hub of radius r0 is calculated, and by counting pulses of a tape length measuring means, a wound tape length 1B is decided. Then, the difference between the tape thickness directly measured by a thickness measuring means and the decided tape thickness is calibrated utilizing a tape roll diameter on the hub after wound and tape winding times. Since the latter tape thickness varies depending on operation conditions of loading devices such as tape's physical characteristics such as surface roughness, tape thickness (d) is calculated with a microprocessor using a mathematical relational expression, d=1Ba/ n<2> B-2r0 /nB, and the tape thickness is used for monitoring/processing while compared to a tolerant error limit.

Title: Phase locked loop circuit
Inventor: ARITA HISASHI
IPC: H03L7/18
Filed: 1985-09-30
Abstract: PURPOSE:To reduce the initial synchronizing lock time when an in-loop frequency division ratio is large by preventing an input clock from being outputted by an AND circuit to the AND circuit of a frequency divider side outputting a frequency-division output discriminated to have a lead phase. CONSTITUTION:When a phase comparator 3 is operated to lead the phase of a comparison frequency FV1, the phase comparator 3 applies phase comparison in the phase of e1-f1 in comparison frequencies FR1, FV1. A control signal phiR descends at the trailing of a phase e1 and rises at the leading of a phase f1 in this case. That is, the phase of comparison frequency FR1 is led more than that of the comparison frequency FV1 by the period of the low level (L) of the control signal phiR. Thus, the phase of the comparison frequency FR1 is retarded equivalently by using the AND circuit 7 and the control signal phiR so as to prevent the input of the input clock to a frequency divider 1 while the control signal phiR is at L thereby placing the phase at the position of the phase e2. Thus, the phase is compared at a phase e2-f2 and the state is brought into a state close to the synchronizing state. Then the input clock and the output clock are synchronized at a phase e4-f4.
