Title: Display device for color overlaying
Inventor: KITAJIMA KENICHI
IPC: G09G5/02
Filed: 1989-01-18
Abstract: PURPOSE:To make an overlay display wherein a contour is sharp by adding such an analog overlay voltage signal that an overlay requiring the sharp contour is white directly to an image voltage signal and supplying the resulting signal to a display device as an analog voltage signal for three primary color components. CONSTITUTION:This device has a contour control signal generation part 6, an overlay three-primary-color component generation part 7, and an overlay three-primary-color component addition part 8. When the decision result of the contour control signal generation part 6 shows a color in which the contour is made sharp, the contour control signal generation part 6 does not output overlap data 24-26. Then a selection control signal 30 controls the overlay three-primary-color component addition part 8 so as to select and output analog voltage signals 27-29 for R, G, and B inputted from the overlay three-primary- color component generation part 7. Consequently, a multicolor overlay display wherein the contour is not sharp can be made as an overlay display wherein only a specific color is white and sharp.

Title: Speech recognizing circuit
Inventor: UKITA TERUHIKO
IPC: G10L25/78
Filed: 1988-01-18
Abstract: PURPOSE:To correctly determine a start edge point and an end edge point and to improve a recognizing performance by reflecting the information of the voice likelihood information of edge point candidates to the calculation of a word similar degree. CONSTITUTION:When an edge point candidate detecting means detects plural start edge point candidates and plural end edge point candidates, a word string evaluating means 6 makes points from plural start edge point candidates up to a prescribed word string evaluation point into a first word, and decides the start edge point by using the word likelihood information of the similar degree and statistical distance, etc., of a first word with a word recognizing means and voice section likelihood information calculated by a voice section likelihood calculation means 3. Further, the end edge point is decided based on the evaluated value of the evaluation point corresponding to the positions of end edge point candidates in the evaluated values of respective word string evaluation points by the word string evaluating means 6 and the voice section likelihood information. In such a way, a decision is executed in which a voice section likelihood is added to the decisions of the start edge point and end edge point. Thus, the probability to decide that a noise is the voice can be reduced, and the recognizing performance can be improved.

Abstract: PURPOSE:To communicate with a terminal of the start-stop system in an analog telephone network without providing an ISDN subscriber terminal with a MODEM by providing a prefix transmitting means, a MODEM pool device designating means, and a MODEM pool device group. CONSTITUTION:When an ISDN subscriber terminal 3 sends packet data to a subsystem 2 through an ISDN switchboard 1, a MODEM pool device designating means 10 transfers it to a MODEM pool device 9-i in accordance with the MODEM attribute value of a prefix transmitting means 7. In the pool device 9-i, data is received by an automatic originating/terminating means 14 and is decomposed to character data by a packet decomposing/assembling means 13 and is transmitted to a terminal 6 of the start-stop system, which is connected to a telephone network 4, through the switchboard 1 by the means 14. When transmission is completed, a bus 11 is disconnected. At the time of transmission from the terminal 6 to the terminal 3, data passes the reverse route. At the time of sending data from the terminal 6 of the start stop system to a packet terminal 16, the automatic originating/terminating means 14 transmits switched packet data to the terminal 16 in the same manner and data is transferred through the switchboard, the subsystem and a packet network 15. It is unnecessary to independently provide the ISDN subscriber with a MODEM.
