Title: Speech detecting device and video switching device
Inventor: NORIMATSU TAKESHI
IPC: G10L15/28
Filed: 1993-09-27
Abstract: PURPOSE:To provide the speech detecting device which can decide a speaker's speech and accurately specify the microphone corresponding to the speaker and the video switching device which can automatically switch an image to the speaker according to the specification. CONSTITUTION:A speech decision part 3 extracts the feature quantity of a spectrum from a signal inputted to a microphone 1 and decides whether or not the signal is a speech according to whether or not there is similarity to the previously found feature quantity of the speech. A speaker detection part 2 estimates the position of the speaker by detecting the difference from the input signal to an adjacent microphone 1 and specifies the microphone 1 corresponding to the speaker. On the basis of the output results of the speech decision part 3 and speaker detection part 2, a total decision part 4 decides only speeches of speakers corresponding to respective microphones 1.

Title: Signal estimation unit with phase-locked loop circuit and phase shift correcting method for received signal
Inventor: MATSUI HITOSHI
IPC: H03M13/41
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To make a phase locked loop circuit highly precise and fast which corrects a phase change in a frequency offset by detecting the phase shift of a receive signal from a replica signal generated from minimum pathmetric history information and the received signal and correcting it by a feedback circuit. SOLUTION: A phase rotator 102 corrects the phase shift of an input two-dimensional received signal, a minimum pathmetric history signal of viterbi algorithm is outputted from a minimum likelihood series estimation unit(MLSE) 103 to a replica generator 105 and convolutional operation between this and a previously found impulse response value of a transmission line is performed to generate a replica signal of the received signal. Then, a phase detector 106 finds a phase difference signal between the replica signal and the output signal of a delay element 104 and a inputs it to a voltage-controlled oscillator 108 through a filter 107 and it is outputted as a phase quantity to be corrected to the phase rotator 102 so that the phase correction of the receive signal is executed. Through this loop operation, phase variation represented by the frequency offset included in the received signal can be absorbed.

Title: Image enjoying mirror for obtaining stereoscopic effect by single image
IPC: G02B27/22
Filed: 1992-07-09
Abstract: PURPOSE:To obtain a stereoscopic effect by locking at one piece of photograph taken by an ordinary camera, and also, to eliminate the harmful effects of eyes caused by looking at a photograph, a television, etc., in a place close by them by constituting the mirror so that the direction of light is varied by a rectangular prism, etc., sight- lines of both eyes are made nearly parallel to each other and images of both eyes are superposed and looked at in the infinity. CONSTITUTION:When light of the screen center 8 passes through 9 and is refracted by prisms 1-3 and reaches the light eye 4, since the right eye 4 looks at the screen center 8 in the direction of 10, images of screens 6, 7 look as if they are in the direction. In the same way, in the case of the left eye 5, the light of the screen center 8 passes through 11 and is refracted by the prisms 1-3 and when it reaches the left eye 5, since the left eye 5 locks at the screen center 8 in the direction of 12, images of the screens 6, 7 are locked at in the direction. In such a way, since both eyes can lock at the screen center 8 by making the lines of sight for both eyes parallel to each other, images of all parts in the screens 6, 7 are also on lines parallel to the lines of sight, respectively, unages of both eyes can be superposed to one and locked at in the direction to infinity, and a stereoscopic effect is obtained.

IPC: H04N5/76
Filed: 1988-09-26
Abstract: PURPOSE:To print many screens without causing a rise of a communication charge and to simplify the operation by storing image data in accordance with a print instruction in the course of connecting a line, and printing the stored data after the line is disconnected. CONSTITUTION:In the course of connecting a line 31, data of a screen to be printed is stored in advance in a storage circuit 42, so that a display screen is printed in accordance with said data after the line is disconnected. In such a way, it is unnecessary to stop a receiving operation in the course of connecting the line 31, therefore, the communication time can be shortened, and the reduction of a communication charge can be contrived. Also, since this device is constituted so that only data of a screen which is brought to print instruction is stored, it is unnecessary to select a screen to be printed after the line is disconnected, and the print operation can be simplified.

Title: Semiconductor laser
Inventor: KASUKAWA AKIHIKO
IPC: H01S5/12
Filed: 1984-11-14
Abstract: PURPOSE:To enable the oscillation of a single longitudinal mode and a single transverse mode and the reduced dependence of an oscillation wavelength on a temperature, and to extremely facilitate the manufacture by arranging a stripe-form diffraction grating which is narrower than the width of the region to become an active medium in an active layer and is narrower than an optical waveguide layer, on the upper or lower plane of the optical waveguide layer. CONSTITUTION:Because a stripe-form diffraction grating 15 which is narrower than the width of the region to become an active medium in an active layer is arranged in an optical waveguide layer 16, the high-output operation of basically longitudinal or lateral mode is possible even if a width of the active layer 17 is enlarged. Also the variation of an oscillation wavelength is smaller than in the usual Fabry-Perot type semiconductor laser even when a temperature changes or the semiconductor laser is modulated directly because a reflectance has a dependence on a wavelength as the diffraction grating 15 is used as a laser resonator. If the diffraction grating 15 is made narrower than the part contributing to oscillation of the active layer 17, the above described effect can be obtained. Accordingly, as the active layer 17 can be formed with considering an error of mask alignment and etc. sufficiently, the manufacture is easy.
