Patent number: 8821978Abstract: A method of forming a layered structure comprising a domain pattern of a self-assembled material utilizes a negative-tone patterned photoresist layer comprising non-crosslinked developed photoresist. The developed photoresist is not soluble in an organic casting solvent for a material capable of self-assembly. The developed photoresist is soluble in an aqueous alkaline developer and/or a second organic solvent. A solution comprising the material capable of self-assembly and the organic casting solvent is casted on the patterned photoresist layer. Upon removal of the organic casting solvent, the material self-assembles, thereby forming the layered structure.Type: GrantFiled: December 18, 2009Date of Patent: September 2, 2014Assignee: International Business Machines CorporationInventors: Joy Cheng, William D. Hinsberg, Ho-Cheol Kim, Young-Hye Na, Daniel Paul Sanders, Linda Karin Sundberg, Hoa D. Truong, Gregory Michael Wallraff, Atsuko Ito

Patent number: 8271288Abstract: 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.Type: GrantFiled: September 22, 2011Date of Patent: September 18, 2012Assignee: Yamaha CorporationInventors: Atsuko Ito, Yasushi Shimizu, Akira Miki, Masato Hata

Patent number: 8265298Abstract: 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.Type: GrantFiled: February 12, 2010Date of Patent: September 11, 2012Assignee: Yamaha CorporationInventors: Atsuko Ito, Akira Miki, Shinichi Sawara

VOICE-SCRAMBLING-SIGNAL CREATION METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM THEREFOR
Publication number: 20080243492Abstract: 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.Type: ApplicationFiled: September 5, 2007Publication date: October 2, 2008Applicant: Yamaha CorporationInventors: Akira Miki, Masato Hata, Atsuko Ito -

Publication number: 20070162299Abstract: Working efficiency improvement of shipping and receiving operations in a materials storage location is contemplated. An optimal location is provided so as to minimize work volume in shipping operation when receiving materials control objects in a materials storage location to improve working efficiency in the materials stockroom. As means to achieve it, a location information of the materials control objects stocked in the materials storage location and vacant area where the materials control objects to be received can be stocked are calculated by use of location information of the materials control objects in the materials storage location and materials dimensions and shape information represented by the three-dimensional CAD used in design to select and decide the area to minimize work volume when shipping. Consequently, shipping operation efficiency can be improved.Type: ApplicationFiled: January 10, 2007Publication date: July 12, 2007Inventors: Atsuko Ito, Kenji Araki, Satoru Ono
