Title: Key control system
Inventor: ISHIKAWA TOSHIRO
IPC: H04L9/06
Filed: 1990-06-05
Abstract: PURPOSE:To prevent an ID from turning itself into the ID of another reception terminal having the same key even when there is ID error to be generated on a transmission line by enlarging a distance between the codes of the ID by adding a redundant bit to the ID. CONSTITUTION:As an ID generating means 131, a redundant part adding circuit 1312 to add the redundant bit is connected to a counter 1311 to generate an order address 1311a to be incremented one by one. Thus, this ID generating means 131 enlarges the distance between the respective codes of the ID to be generated. The ID generated from the above-mentioned ID generating means 131 is inputted to a key storing means 14 and while combining a random number train 13d from a random number generating means 132 and the address, a ciphered key 14a to be generated at random corresponding to the random number train 13d is applied to each ID.

Title: Encoder, decoder and encoding method
Inventor: MURASE TAKAFUMI
IPC: H04N19/423
Filed: 1992-05-15
Abstract: PURPOSE:To easily reduce the code volume to a prescribed value or smaller and to reduce the gradation of the picture quality by copying a quantized picture and comparing it with the original picture to detect the error and controlling a variable length encoding means. CONSTITUTION:A DCT circuit 2 performs the DCT processing of the picture, and the DCT coefficient is outputted to a quantizing circuit 3 to be quantized. The DCT coefficient is multiplied in a multiplier by alpha and quantized and encoded to a variable length code by a VLC circuit 5. It is inversely quantized by an inverse quantizing circuit 7, and this output is compared with the inputted picture, and the error of the output of the circuit 7 is detected by an effective error discriminating circuit 9 and stored in an error memory 10. The stored error is successively coded from the MBS plane of the error by bit plane encoding circuit 11. A code volume counter 6 controls the circuit 11 in accordance with the code volume outputted from circuits 5 and 11. Thus, the code volume does not exceed a target code volume, and the code volume from circuits 5 and 11 is easily reduced to the prescribed value or smaller, and the degradation of the picture quality due to the abortion of coding is reduced.

IPC: G11B15/60
Filed: 1982-08-26
Abstract: PURPOSE:To simplify a tape driving system and to improve the input/output characteristics of a magnetic head, by providing a limiter which controls the position of the magnetic tape width direction at one or both of the upper and lower ends in the width direction of a magnetic head main body so that the limiter has a light touch to the edge of a magnetic tape. CONSTITUTION:A limiter 8 which controls the tape width direction variation while a tape 3 of a record/reproduction magnetic head 5 is traveling toward an arrow (a) is set flat so that a projecting degree delta larger than the thickness of the tape 3 is secured at the upper part of the main body of the head 5 and that the limiter has a light touch to the edge of the tape 3. Otherwise pins 9 and 9 are provided at both upper sides of the head 5 in place of the limiter 8. It is also possible to set the limiter at the lower part or both upper and lower parts of the head 5. Thus a tape guide pin containing a limiter is not required, and therefore the tape vibration is eliminated. This can stabilize the input/output characteristics and at the same time simplify a tape driving system.
