Title: Magnetic recorder-reproducer
Inventor: FUJIKAWA AKINOBU
IPC: G11B15/30
Filed: 1978-04-20
Abstract: PURPOSE: To make setting of the timing of operation sure, prevent the production of click noise and enhance the stability of operation by operating a tape take-up means after a tape constant speed running means has come into operation.  
     CONSTITUTION: At the operating for tape constant speed running such as recording and reproducing operations, the constant speed driving of a tape 33 is accomplished by the tape constant speed running means consisting of a pinch roller 20 and capstan 21 first, then an idler 24 is contacted to pulleys 22, 8, by which the take-up torgue from a motor 23 is applied to a take-up reel turntable 5. Hence, the tape 33 is driven only by the take-up torque and passing of the tape in front of heads 12, 13 at the speed higher than that at the constant speed driving does no longer occur. Even if the bias signal is recorded, its outputting as click noise at the reproducing does no longer occur.

Title: Slice level controller for teletext data extracting circuit
Inventor: SOBASHIMA HIROSHI
IPC: H04N7/035
Filed: 1987-03-03
Abstract: PURPOSE:To correctly extract teletext data by allowing a slice level control circuit to switch a slice level when the center level of amplitude of a character signal is shifted from a normal value, and to control the feedback of a detection output from an error rate detecting circuit in its reducing direction. CONSTITUTION:When the center level of amplitude of a character signal to be sampled is shifted from the normal value to the high or low side due to noise, group delay, ghost or the like, the detection output of the error rate detecting circuit 15 is changed. The slice level control circuit 20 controls a slice level switching circuit 13 based on the detection output so that the slice level is switched to the high or low side and controls the feedback of the detection output of the circuit 15 in the reducing direction (error rate reducing direction). Consequently, a noise margine corresponding to an interval between a character signal and a slice level at the leading time of an extracting clock can be maximized and the teletext data can be correctly extracted.

Title: Method and device for processing video of telecine
Inventor: TAMURA YOICHI
IPC: H04N5/93
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To reproduce a natural animation by generating a vertical synchronizing signal of n-times as large as 24 Hz from a telecine-processed input video signal of 60 Hz so as to convert the portion of all the frames to a video signal of the same time width similarly to a movie film. SOLUTION: A vertical synchronizing signal of 72 Hz being three times as large as 24 Hz is generated from the input video signal of 60 Hz telecine- processed to 60 fields/sec and a frame is updated every 3/72 (1/24) sec by this vertical synchronizing signal. Whenever an input video signal is inputted by 5 fields, the input video signal and an output video signal are synchronized with each other to absorb an hourly error stored while the output video signal is generated asynchronously. As a result, the same video signal corresponding to one frame of the movie film is continually outputted by the portion of three frames and a video signal corresponding to a new frame is updated every 3/72 Hz (1/24 Hz), thereby the portion of all the frames can be converted to the video signal of the same time width being 1/24 Hz similarly to the video film.
