Title: Method and device for grinding wafer
Inventor: SHIMURA TAKASHI
IPC: B24B37/07
Filed: 1979-10-22
Abstract: PURPOSE:To improve the lapping precision for the silicon wafer by detecting the thickness of the wafer and the number of rotation of the grinding mechanism and by operating the final number of rotation based on the thickness of the wafer at a set number of rotation. CONSTITUTION:The rotational numbers N1 and N2 of a lapping mechanism provided in the main body 1 of a lapping machine are detected by a rotational-number operating part 2 and thickness of the wafer t1 and t2 at the same point of time is measured by a wafer-thickness measuring part 3. Based on these values, the lapping speed in the pertinent period (t1-t2)/(N2-N1) is operated by an automatic sizing control part 5, thereby the rotational number NEND at which the thickness of the wafer reached a value set by a setting part 6 is operated, an the main body of the lapping machine is stoped at NEND by operating the control part 4 of the main body, whereby the wafer of the required thickness can be obtained with high precision.

Title: Picture encoding method and device therefor
Inventor: MURDOCK JOHN ASHLEY
IPC: H04N7/30
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a macro block bit adjustment system for improvement of the quantization and variable length encoding of a video encoder by encoding a macro block and applying a constraint pattern to the macro block when precedent (n) macro blocks included in a row exceed the limit value of bit rate. SOLUTION: A quantization unit 673 quantizes the DCT(discrete cosine transform) coefficient sent from a DCT unit and outputs this quantized coefficient to a VLE(variable length encoding unit). A pattern constraint logic 710 is added to the unit 673 to access one or plural programmable constraint patterns 712. It's decided whether the constraint is necessary or not based on the bit rate of a macro block or on a fact whether two precedent macro bits included in a row exceed the limit value of bit rate. Thus, the optimum balance is secured between the bit rate and the picture quality.
