Title: Speech recognition device
Inventor: HAGIMOTO NOBUO
IPC: G10L21/02
Filed: 1990-05-10
Abstract: PURPOSE:To eliminate the influence of a noise upon speech recognizing ability by inputting the outputs of two microphones which gather a voice and a noise mainly to two filter banks which are equipped with band-pass filters by plural channels, and subtracting the outputs of corresponding channels by respective subtracting circuits. CONSTITUTION:The voice input and noise component which are gathered by the two microphones 11 and 12 are outputted to the filter banks 15 and 16 through analog processing circuits 13 and 14 respectively. Those filter banks 15 and 16 branch the voice input and noise by plural frequency bands and subtracting circuits 17-1 to 17-n perform subtraction as to outputs of corresponding frequency bands. Thus, the signals which are gathered by the two microphones and outputted to the filter banks are processed by subtraction, channel by channel, to cancel the noise components which contribute to the smoothing outputs of the filters. Consequently, even when the device is used in noisy environment, deterioration in speech recognizing performance due to the noise is prevented.

IPC: H05B3/00
Filed: 1989-05-15
Abstract: PURPOSE:To decrease heat loss, to reduce the quantity of variation of the lengthwise temperature distribution on the surface of a heat roller depending upon the width of a base, and to secure uniform fixation performance by recessing at least part of the internal wall of a heat roller heat insulating member inside below the end surface of the heat roller. CONSTITUTION:The heat roller heat insulating member 5 has part of its internal wall recessed inside below the end side of the heat roller 1 and also has a conic hole where a heat source 3 provided nearby the center of rotation of the heat roller 1 is passes. This structure reduces the quantity of radiating heat of convection and radiation from the internal surface and end surface of the heat roller 1 and also decreases the quantity of variation of the lengthwise temperature distribution with the width of passed paper, so even when a base which is a half as wide as maximum paper passing width is passed, the possibility that the temperature of the base non-passing part of the heat roller rises unnecessary to high temperature is reduced. Consequently, the uniform fixation performance is obtained irrelevantly to the width of the base and heat efficiency becomes high.

Filed: 1988-05-17
Abstract: PURPOSE:To enable direct detection of the residual amount of an ink sheet by using a lookup table storing the relation between the residual amount of the ink sheet and the rotating angle of a bobbin. CONSTITUTION:An ink sheet 6 wound round a pay-out bobbin 5 is used for transferring images onto a printing paper by a thermal head 7, and is taken up by a take-up bobbin 8. As the residual amount of the ink sheet 6 is reduced, the roll diameter of the ink sheet on the pay-out bobbin 5 is reduced, while the rotating angle of the pay-out bobbin 5 is increased. Therefore, there is a fixed relation between the residual amount of the ink sheet 6 and the rotating angle of the bobbin 5. The rotating angle of the bobbin 5 of the ink sheet 6 for paying out a predetermined length of the ink sheet 6 is measured beforehand by an encoder 1, for every value of the residual amount of the ink sheet 6, and the relation between the residual amount of the ink sheet 6 and the rotating angle of the bobbin 5 is stored in a lookup table 3. The residual amount of the ink sheet is read from the lookup table 3, and is displayed on a display element 4.

Inventor: MIYAMOTO JIICHI
IPC: G11B11/10
Filed: 1990-05-10
Abstract: PURPOSE:To enable overwriting with high sensitivity without a danger of erasing the recorded information with reproducing light by applying a bias magnetic field on the magneto-optical recording medium in a different direction or with different intensity from the bias magnetic field used on recording when the recorded information is to be reproduced. CONSTITUTION:Magnetization of the first magnetic layer 3 of the medium is transferred to the second magnetic layer 4 with reproducing bias magnetic field on overwriting, and thereby, the first magnetic layer 3 and the second magnetic layer 4 have the same magnetization direction. In this state, a light beam for reproducing is made to irradiate the medium. The magnetization of the first magnetic layer 3 and second magnetic layer 4 is oriented to give exchange coupling to each other, and this state is stable and can not be changed even when the reproducing light has same intensity as the low level of light for recording. Thereby, breaking of the recorded information is avoided even when irradiated by reproducing light of large intensity, and high-sensitive overwriting can be performed.
