Title: Tape running controller
Inventor: KAWAMATA NAOKI
IPC: G11B15/46
Filed: 1993-12-24
Abstract: PURPOSE:To suppress fluctuation in tension to a min. when tape speed is changed. CONSTITUTION:Values on the supply side and the take-up side are detected by tension detectors 5 and 6 respectively, while running speed of the magnetic tape 4 is detected by a tape traveling speed detector 8. Rotational angular velocity of a reel 3 is also detected by a reel rotational angular velocity detector 29, and these detected values are inputted to a 1st parameter matrix calculation part 26 and a 2nd parameter matrix calculation part 27 respectively. Then, matrix calculation is carried out with parameter matrices set in these parts 26 and 27 to calculate control inputs, and based on these calculated results, two reel motors 9 and 10 are cooperatively controlled. Thus, fluctuation in tension under the transient state is reduced in such a way that an error is reflected also to the diagonal side by a value of a nondiagonal element of each matrix, so that the speed and the tension are satisfactorily controlled.

Title: Switching mechanism of tape running modes for tape recorder
Inventor: MASUDA HIROAKI
IPC: G11B15/02
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To provide a simple and cheep lever operation mechanism for a tape recorder in which switching of tape running modes are performed in an electronic controlling manner by an operation of a light contact button. SOLUTION: A main gear 28 as a sun gear and a sub gear 29 as a planetary which rotates around the main gear while always engaging with the main gear, are used. Control members 60 and 61 having a gear are rotated by the sub gear which is moved in reciprocal and rotating manners. These control members 60 and 61 having a gear cause tape running mode switching levers 100 and 101 to swing and rotate, so that first reel gears 40A and 50A and second reel gears 40B and 50B of reel gear assemblies 40 and 50 are caused to be selectively moved so as to get engaged with the sub gear. Thus, a tape is set to run at a normal running speed or a high speed.

Filed: 1994-12-28
Abstract: PURPOSE: To minimize skew distortion and noise by allowing a microcomputer to detect a horizontal synchronizing phase shift caused at head changeover at recording and reproduction and supplying a current equivalent to the phase shift to an AFC at head changeover. CONSTITUTION: A reproduced video signal from a VTR 1 is outputted to an AFC circuit 2 and the video signal includes a horizontal synchronizing phase shift caused at head changeover at recording and reproduction. Furthermore, a head changeover pulse from the VTR 1 is given to a microcomputer 4.
