Filed: 1990-11-20
Abstract: PURPOSE:To obtain the title detection body capable of ensuring stable detection characteristics by directly forming recessed and protruding parts to the outer peripheral surface of the rotary shaft of a magnetic body. CONSTITUTION:Recessed and protruding parts, for example, teeth 13a are directly formed to the outer peripheral surface of the end part of the rotary shaft 12 of a magnetic body. A magnetic rotation sensor 4 is arranged in the direction crossing the shaft 12 at a right angle. Further, teeth 13a' may be directly formed to the end surface 12a' of a shaft 12'. In this case, the sensor 4 is arranged at the position opposed to the end surface 12a'. Further, the sensor 4 may be formed as a sensor 4' equipped with a plurality of magnetoelectric converter elements DT coaxially arranged outside the teeth 13a. Since the teeth 13a are directly formed on the rotary shaft 12, assembling work can be reduced and, since the eccentricity of the teeth 13a to the rotary shaft 12 can be reduced, the lowering of detection accuracy can be prevented.

Title: Variable length coder
Inventor: SHIGESATO TATSURO
IPC: H04N19/61
Filed: 1990-11-20
Abstract: PURPOSE:To prevent deterioration in the efficiency of a high efficient coding by recording other information than an end of block(EOB) to a final bit of a code word representing the EOB. CONSTITUTION:A quantized value inputted from an input section 1 is inputted to a code bit separation section 3, in which the value is separated into an absolute value and a code bit representing the positive and negative sign. The separated absolute value is subject to variable length coding at a variable length code(VLC) section 4, and a least significant bit(LSB) of a block number during processing is outputted from an LSB input section 2 to a data selection section 5 simultaneously, which outputs an LSB when a code word outputted from the VLC section 4 is an EOB and outputs a code bit in other case. Moreover, a 1-bit insertion section 6 inserts 1-bit selected by the selection section 5 to a final bit of the code word outputted from the VLC section 4 and outputs the result to an output section 7. Thus, the LSB is recorded in the final bit of the EOB. Thus, the deterioration in the efficiency of the high efficient coding is prevented.
