Title: Echo canceller
Inventor: HAYASHI KENSUKE
IPC: H04L25/02
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To reduce the estimation error of an impulse response, when a double talk occurs and to prevent the deterioration of echo cancel quantity by using a delay impulse response dalayed, compared to the time sequence of a reception input signal. SOLUTION: A register 104 calculates the correction quantity of an estimation impulse response by setting a shift register 100 storing the reception input signal Xn at every input time sequence, a shift register 101 storing a transmission output signal at every input time sequence, a resister 102 calculating the power of the register 100 and a time constant μ 103 to be inputs. An adder 107 adds the output (b) of the register 104 and the output of the register 105 storing the impulse response, and it therefore corrects the delayed time sequence of the impulses response. A computing element 108 convolutes the impulse response obtained by correcting delays and the register 100 and generates a pseudo-echo signal. An adder 30 subtracts the pseudo-echo signal from a transmission input signal dn, canceling an echo and setting it to be the transmission output signal.

Title: Area dividing method
Inventor: MOTOIKE JUN
IPC: G06T1/00
Filed: 1993-05-06
Abstract: PURPOSE:To stably divide even a particle image that has the density difference or the color tone difference by applying the filtering processing to the particle image for each divided area based on the threshold value set on the basis of the background density defined by the density information and the color tone information when the particle image included in a fluid is defined as a static image and a desired subject is extracted out of the static image. CONSTITUTION:A bright part which is not identical with a particle image is extracted as a background part, and the threshold value is set for each density and color tone based on the background part. In regard of the distribution of subject images in a color space, the background, a blue subject, and a red subject are shown in BG, B and R respectively when the density of a line component (g) image is set on an axis (x) together with the density of a red component (r) image set on an axis (y) respectively. Furthermore a (g-r) image and a (g+r) image are set on the axes defined by turning the axes (x) and (y) by 45 deg. respectively. The threshold values T2, T12, T21 and T31 which divide the subjects B and R are calculated from the histograms of the (g-r) and (g+r) images. The areas are divided by these threshold values and then an image pattern is shaped by the image filtering processing.

Filed: 1985-05-17
Abstract: PURPOSE:To enable a plating to be easily removed with use of a knife or the like without imparting a flaw, deformation or interior strain to a substrate plating or a roll substrate, by a method wherein Ballard plating is conducted after adhesion of a non-conductive member having a curved trimming portion, and the reversely shaped Ballard plated part to the curved trimming portion in shape is peeled, and the peeling ranges the whole plating. CONSTITUTION:A non-conductive adhesive tape 4 of an appropriate form having a radially directed curved trimming portion 4a is adhered on the portion on a roll end surface 1 to be applied Ballard plating. Ballard plating (copper plating) 5 is conducted; while a chuck hole is chucked by an energized base material C on the plating device side to ensure the prevention of infiltration of intensifier into the inside, and the roll is rotated with being immersed in the intensifier. After completion of printing, the peeling of the Ballard plating is started from a plated portion 5a of peninsular-shape which is higher than the adhesive tape 4 to obtain a peeled pieced.

Abstract: PURPOSE:To keep a motor in a stop state even if a take-up shaft is caused to go over a set stop position by weight inertial of a screen, and it exceeds a set count value by controlling the motor to be turned off by a switch when counter counts the set count value as a screen stop position. CONSTITUTION:Though a screen 13 is weighty so that a self-lock mechanism of a motor is caused to make incomplete operation by its weight inertia to control a motor to be turned off, if a take-up shaft 2 is turned excessively, a count wheel 27 for the lower figure of a counter 17 is moved in the direction to a higher figure step by step by the excessive movement, but a count shaft 29 for the highest figure can never be reached. That is, the count wheel 29 is adapted to keep a limit switch 50 in off-state through a switch operation lever 47 to prevent the motor from being driven again, whereby the motor is reliably controlled and stopped to prevent reckless driving of the screen 13.

Title: Recognition result discarding method in pattern recognition process and pattern recognition device installing the method
Inventor: OBUCHI YASUNARI
IPC: G10L15/28
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To discriminate whether to discard a recognition result or not with a simple process without conducting correction by comparing a standard degree of similarity distribution and the degree of similarity distribution of each element with respect to an input pattern and digitizing the compatibility of both distributions. SOLUTION: In a feature collating section 106, plural standard patterns included in a beforehand prepared recognition object list 112 and an input pattern are collated and the degree of similarity with respect to individual is computed. The section 106 outputs the degree of similarity distribution, in which the degree of similarities with respect to each element of the list are arranged, and transmitted to a recognition result discrimination section 108. The section 108 selects a most appropriate element among the list 112 based on the degree of similarity distribution with respect to the input and the element is set as a recogniton result. Then, a standard degree of similarity distribution with respect to the recognition result is taken out from a standard degree of similarity distribution list 114 and compared with the degree of similarity distribution with respect to the input.  Based on the result of the comparison, a signal that selects the recognition result is outputted. When the result is to be discarded, a signal that instructs discarding is outputted.
