| 20080235008 | Sound Masking System and Masking Sound Generation Method - In a masking sound generation apparatus, a CPU analyzes a speech utterance speed of a received sound signal. Then, the CPU copies the received sound signal into a plurality of sound signals and performs the following processing on each of the sound signals. Namely, the CPU divides each of the sound signals into frames on the basis of a frame length determined on the basis of the speech utterance speed. Reverse process is performed on each of the frames to replace a waveform of the frame with a reverse waveform, and a windowing process is performed to achieve a smooth connection between the frames. Then, the CPU randomly rearranges the order of the frames and mixes the plurality of sound signals to generate a masking sound signal. | 09-25-2008 |
| 20080243492 | VOICE-SCRAMBLING-SIGNAL CREATION METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM THEREFOR - Original voice uttered in a first space is acquired via a microphone and a series of digital waveform data of the acquired original voice are obtained. The waveform data are sequentially segmented into plural frames and the waveform data of the individual frames are written into a memory. In parallel with writing, into the memory, of the waveform data, individual ones of the frames already written in the memory are sequentially or randomly selected and read out in a direction opposite to a direction the waveform data of the frame have been written so that a reverse-reproduced voice signal is generated. As the original voice is transmitted, as a leaked voice from the first space to a second space near the first space, a scrambling voice based on the reverse-reproduced voice signal is spatially mixed with the leaked voice in the second space. | 10-02-2008 |
| 20100150372 | Loudspeaker system - A hands-free loudspeaker system which is capable of achieving high-quality voice amplification without requiring a human speaker to move to a microphone or a microphone to be moved to a human speaker. A microphone whose input level has continued to be above a threshold value for not shorter than a predetermined time period is detected, based on input signals from dispersedly arranged microphones. An input signal from the microphone is selected and outputted to a loudspeaker at an output level or with a delay time, according to a location of the loudspeaker. A preset lowest threshold level is initially set to the threshold value, and an input level of the microphone higher than the threshold value is newly set to the same, while when the input level is lower than the threshold value, a lower value is set to the same in a step-by-step manner. | 06-17-2010 |

| 20090147161 | REFLECTIVE SPATIAL LIGHT MODULATOR - The present invention relates to a reflective spatial light modulator enabling improvement of light resistance and prevention of damaging of the liquid crystal layer. The reflective spatial light modulator controls phases of the incident light and a reflected light while reflecting light made incident from a front side, and comprises a liquid crystal layer, a dielectric multilayer film, and a phase shift layer. The liquid crystal layer is filled with a liquid crystal comprised of a light modulating material, and modulates the incident light. The dielectric multilayer film reflects the incident light. The phase shift layer is disposed between the liquid crystal layer and the dielectric multilayer film to shift phases of the incident light and the reflected light at an interface of the liquid crystal layer. | 06-11-2009 |

| 20120031256 | TONE GENERATION APPARATUS - In response to detection of a note-on instruction, a CPU assigns a tone generating unit comprising two tone generating channels and sets tone color control data of the assigned tone generating unit into tone generator registers. The tone color control data includes a parameter common to the two channels. Once the CPU gives a tone generation start instruction to a tone generator, the tone generator accumulates a frequency number common to the two channels to thereby generate a progressive phase common to the two channels. Waveform readout section reads out left-channel and right-channel waveform data from a waveform memory on the basis of the phase and waveform selecting information of the left and right channels. Tone characteristics of the read-out left- and right-channel waveform data are controlled by a characteristic control section on the basis of a characteristic control parameter common to the two channels. | 02-09-2012 |

| 20080211403 | Photomultiplier - The present invention relates to a photomultiplier having a structure that enables to perform high gain and satisfy higher required characteristics. In the photomultiplier, an electron-multiplying unit accommodated in a sealed container comprises a focusing electrode, an accelerating electrode, a dynode unit, and an anode. Particularly, at least the accelerating electrode and dynode unit are held unitedly in a state that at least a first-stage dynode and a second-stage included in the dynode unit are opposite directly to the accelerating electrode not through a conductive material. A conventional metal disk for supporting directly dynodes which are set to the same potential as that of the first-stage dynode is not placed between the accelerating electrode and dynode unit; thus, variations of the transit time of electrons may be drastically reduced while the electrons reach from the cathode to the second-stage dynode via the first-stage dynode. | 09-04-2008 |
