Title: Vector quantization method and device therefor
Inventor: NAKANO KEIICHI
IPC: H04N19/423
Filed: 1991-12-05
Abstract: PURPOSE:To efficiently retrieve an optimum code book vector at a high speed by calculating a distortion upper limit and its lower limit, setting them, updating them and comparing them. CONSTITUTION:A distortion calculation section 22 extracts a vector from a code book 100, calculates the distortion of an input vector X, calculates the sum U of all dimensions and sets the result as an upper limit value. On the other hand, a lower limit calculation section 23 uses a sort table 200 to calculate a lower limit L from the base of a code book vector(CBV) and the vector X and sets the result. Then a comparator section 25 compares U with L and the processing is terminated in the case of U=L. On the other hand, in the case of Unot equal to L, a distortion partial sum Sj up to j-degree is obtained through the comparison with a succeeding CBV and the result is sent to the comparator section 25. In the case of Sj>=U, the further calculation is stopped and the object is transferred to the succeeding CBV. When the distortion calculation is not stopped, the processing updating the U, L is implemented and the processing is implemented till the relation of U=L is obtained. Thus, the optimum CBV with respect to all input vectors is retrieved efficiently at a high speed.

Subsequently, an N-type InP layer 17 is burried on the N-type InP layer 12 by using the mask 16. Then, a groove 18 is formed concentrically with the mask 16 by etching. Then, after a silicon nitride film 19 is formed on the surface of a crystal, a P-type electrode metal 20 and an N-type electrode metal 21 are formed. Thus, a light emitting diode array having not only the P electrode but also the N electrode independent of each other can be constructed.

IPC: G01N11/14
Filed: 1990-11-28
Abstract: PURPOSE:To enable viscosity of a liquid to be measured highly accurately and easily by providing a flange for receiving a liquid which is overflown from a cup on an outer surface of the cup. CONSTITUTION:A flange 2 is retained on an outer surface of a cup 1 so that it can be moved by an O-ring 3.

Although a slight amount of liquid is overflown from an upper edge of the cup 1 when the inner cylinder is rotated, the overflown liquid entirely enters an inside of the flange 2 and does not contaminate an outside. Also, an upper surface of the liquid is maintained to be at an upper edge part of the cup 1 constantly during measurement and a contact area among the liquid, the cup 1, and the inner cylinder does not fluctuate, thus enabling viscosity to be measured with an extremely high accuracy.

Title: Image display device
Inventor: HOTTA TERUO
IPC: H04N5/445
Filed: 1994-11-30
Abstract: PURPOSE: To improve the definition of on-screen display in an image display device which doubles the number of the scanning lines of a video signal and shifting the scanning lines in a vertical direction (so called a Wobbling system). CONSTITUTION: A horizontal synchronizing signal and a vertical synchronizing signal, which are separated by a synchronization separation circuit 2 from an input video signal, are supplied to a field discrimination circuit incorporated in an on-screen display control circuit 11a, and the odd/field fields of the video signal are discriminated. In the case of the even field, the on-screen display control circuit 11a outputs a font which is different from the font position of the odd field by one horizontal period. Thus, display contents become equal on adjacent even line and odd line in the odd field and the even field and therefore the dignity of on-screen display is not deteriorated even if a Wobbling operation is executed.
