Title: Servo circuit for vtr
Inventor: HASHIRANO MASARU
IPC: G11B15/467
Filed: 1987-11-25
Abstract: PURPOSE:To attain a servo to make a sampling frequency into a frame frequency and a servo to make it into the (n)-fold frequency by switching and using one phase control means. CONSTITUTION:A first switching means 15 automatically selectively switches and outputs a frame synchronizing signal S1 and the output S2 of a multiplying means 3 by a switching signal S8 from a terminal 2. An output control means 17 switches the frequency-dividing signal S5 of a rotation detector 12 or a head switching signal S4 in accordance with the polarity of the signal S8 and outputs it to a second switching means 18. A normalizing means 19 normalizes the switching signal S8 with the frame synchronizing signal S1, switches outputs S13 and S14 of the means 17 through the means 18 and outputs them to a phase control means 16. The means 16 switches the action condition by the signal S8, and when the signal S1 is inputted, comparing is executed with a frame frequency and when the signal S2 is inputted, the comparing is executed with the (n)-fold frequency. Consequently, the servo of the frame frequency and the (n)-fold frequency can be executed only by the means 16.

Filed: 1985-12-28
Abstract: PURPOSE:To prevent at ink ribbon from being caught, by moving a carriage and moving the ink ribbon in a circulative manner while stopping a printing head, thereby applying a tension on the ribbon. CONSTITUTION:A controlling circuit 14 checks whether or not a color region of an ink ribbon set in position coincides with a color region designated by a host system. When the color region of the ink ribbon does not coincide with the designated color region, the circuit 14 calculates the amount by which the ribbon is to be shifted in the width direction for bringing the designated color region into contact with a printing head, sets an amount by which a carriage is to be moved, judges the direction in which the carriage is to be moved, and sets the moving direction. A shifting motor is started, a carriage motor is started, and it is judged whether or not the ink ribbon and the carriage have moved respective predetermined distances. Thus, when shifting the ribbon in the width direction, the circuit 14 controls a carriage motor driving circuit 18 to move the carriage. As a result, the ink ribbon is circulatively moved as the carriage is moved, whereby a tension in the moving direction of the ribbon is exerted on the ribbon, so that the ink ribbon is not caught when being shifted in the width direction.

Title: Angular displacement detector
Inventor: NAKAZAWA ISAO
IPC: G01C19/00
Filed: 1988-11-25
Abstract: PURPOSE:To find angular displacement by a lightweight, small-sized device speedily with excellent sensitivity by detecting momentary shifts in the absolute position and relative position of a floating body by at least two detection parts. CONSTITUTION:At time (t) (0<=t<=t1), a slit image formed on the side of a photodetector 6 is close to the center of a light reception surface 6a, so a selecting circuit 16 employs the output signal of the photodetector 6. At t=t1, the levels of the element 6 and a light reception element 8 become equal and at t>t1, a slit image formed on the side of the element 8 becomes close to the center of a light reception surface 8a, so the selecting circuit 16 employs the output signal of the element 8. The output signal selected by this circuit 16 becomes discontinuous at t=t1. Therefore, the (A-B) output of a detecting circuit is differentiated 17 and inputted to the circuit 6 as a speed signal. This speed is irrelevant to the light reception surface slit images and the speed signals of the elements 6 and 8 are the same. Therefore, even when the circuit 16 is switched, the output signal is continuous and a signal which is integrated 18 indicates a real displacement signal.
