Title: Voice recognition device
Inventor: KUBOTA SHUJI
IPC: G10L15/18
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To evade erroneous recognition by outputting a recognition result candidate the highest in similarity as the first rank of the recognition result when there is not difference in overlapped frame length axists. SOLUTION: A dictionary collation part 4 outputs the recognition result candidate when the similarity between a characteristic vector for every frame converted by a characteristic extraction part 3 and a voice standard pattern registered in a word dictionary 1 exceeds a threshold value α. Then, a frame superposition judging part 9 in a recognition result selection part 7 sends the recognition result candidate that the frame of a certain recognition candidates don't overlap the frame of another recognition result candidate in the same voice section detected by a voice section detection part 6 to a recognition result output part 8, and sends the recognition result candidate overlapping each other to a frame length comparison part 10.  The frame length comparison part 10 selects the recognition result candidate with the longest frame length to send it to the recognition result output part 8, and sends the recognition result candidate with no difference of the superposition frame length to a similarity judging part 11. The similarity judging part 11 sends the recognition result candidate with the largest similarity to the recognition result output part 8.

Title: Power transformer
Inventor: ISHIKITA HISAO
IPC: H01F30/00
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To reduce the distortion of power voltage waveform or the loss of a transmission line by suppressing the peak current values of a primary current and a secondary current, thereby making them into currents with few higher harmonic components. SOLUTION: An iron core piece 5 and a magnetic plate 6 cooperate to form a magnetic path, and the formed magnetic path gives a secondary winding 4 inductance, piercing the secondary winding 4 arranged on the periphery side. Thus is becomes equivalent to a case where a reactor is connected in series to one winding, and even in the case that a capacitor input type of rectifying circuit is connected to an output side, this transformer can make the current into one with few higher harmonic wave components, by suppressing the charge current of the capacitor and suppressing the peak current value of the current flowing in a primary winding 3 or a secondary winding 4. As a result, the distortion of the power voltage waveform or the loss of a transmission line can be reduced.

Title: Printer, method for printing and recording medium
Inventor: ASAUCHI NOBORU
IPC: B41J19/14
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To suppress density variation or granulation due to deviation of a dot formed position in a multi-value printer that forms a plurality of dots for each pixel. SOLUTION: Ink drops are continuously ejected to each one pixel during the main scanning in this ink jet printer. Multi-gradation can be represented by each pixel corresponding to the number of dots. A pattern for forming a dot is set such that a center of gravity of whole dots formed on each pixel is in conformity with a center of gravity of the pixel. As a result, it is possible to suppress deviation of dots in the pixel, thereby suppressing density variation or granulation. Particularly, it is possible to suppress a shift of the dot formed positions between outward and inward movements when bi-directional printing is executed, thereby achieving a high quality printed result.
