Title: Multistage amplifier
Inventor: UCHIDA HIROMITSU
IPC: H01P3/08
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration of a gain and the increase of noise caused by resistance by multistage-connecting plural unit amplifiers arranging two resistors with operation frequency at an interval of 1/4 wavelength on a micro- strip liens so as to adjust the passing phase between respective stages. SOLUTION: In the multistage amplifier, first-stage amplifiers 11 and 12 are matched, the micro-strip line 13 is for adjusting a passing phase, and resistors 14 and 15 are connected to the output side of the first-stage amplifiers. In addition, in an isolated line 16, the resistors 14 are arranged at an interval equivalent to 1/4 wavelength in operation frequency on the micro-strip lines. The unit amplifier consists of the first-stage amplifiers, the micro-strip circuit 13 and the two resistors 14 and 15, and plural unit amplifiers are multistage- connected. As the plural unit amplifiers are multistage-connected, by adjusting the passing phases between respective stages by varying the length of each micro-strip line, the values of the resistors are reduced to reduce the deterioration of a gain and the increase of noise caused by resistance.

Title: Character recognizing device
Inventor: KAMI HIROYUKI
IPC: G06K9/62
Filed: 1985-08-22
Abstract: PURPOSE:To shorten collating time by suspending calculation for the sum of products of the residual part of distance calculation and starting the succeeding vector distance calculation when a distance obtained up to the way of distance calculation is larger than the maximum distance. CONSTITUTION:A document signal photoelectrically transduced by a measuring means 1 is inputted to a feature extracting means 2 and its feature is extracted. At the distance calculation of a feature vector obtained from a character pattern and a feature vector obtained from a dictionary, a distance calculation control means 4 finds out a distance which is an accumulation of the previously determined number of repeating times of a distance between elements. Then, the means 4 compares the found distance with the maximum distance which is a signal outputted from a proposed distance storing means 5. When the maximum distance is smaller than the found distance as the result of the comparison, the distance calculation for the residual elements is suspended and control is transferred to the distance calculation using a feature vector of the succeeding reference pattern obtained from a dictionary storing means 3. When the maximum distance is larger, the distance calculation processing is repeated by the determined number of times.
