Publication number: 20100226507Abstract: A microphone unit comprises first and second microphones and a delay element. When sound is input to the first and second microphones, the delay element delays an output signal of the first microphone so as to detect the sound by a difference signal between the output signal of the first microphone and an output signal of the second microphone. The delay element delays the output signal of the first microphone so as to satisfy relation 0.76?D/?r?2.0 where D is amount of delay for the output signal of the first microphone while ?r is distance between the first and second microphones. The relation D/?r?2.0 can reduce far-field noise, while the relation 0.76?D/?r can increase the detection sensitivity to sound emitted from a null point.Type: ApplicationFiled: March 3, 2010Publication date: September 9, 2010Applicant: Funai Electric Co., Ltd.Inventors: Ryusuke HORIBE, Rikuo Takano, Fuminori Tanaka, Takeshi Inoda

Publication number: 20100226522Abstract: A microphone unit comprises a vibratory diaphragm for detecting sound input through its first and second openings. The sound input through the first opening is guided to a front surface of the vibratory diaphragm while the sound input through the second opening is guided to a rear surface of the vibratory diaphragm so as to detect the sound by the vibration of the vibratory diaphragm. The microphone unit satisfies relation 0.76?D/?r?2.0 where D is difference in time between the sound propagation time from the first opening to the front surface of the vibratory diaphragm and that from the second opening to the rear surface of the vibratory diaphragm, while ?r is distance between the first and second openings. The relation D/?r?2.0 can reduce far-field noise, while the relation 0.76?D/?r can increase the detection sensitivity to sound emitted from a null point.Type: ApplicationFiled: March 8, 2010Publication date: September 9, 2010Applicant: Funai Electric Co., Ltd.Inventors: Ryusuke HORIBE, Rikuo Takano, Fuminori Tanaka, Takeshi Inoda

Patent number: 4175266Abstract: A pair of deflection electrodes at least one of which is grooved are provided to confront with each other in an ink jet system printer in order to deflect charged ink droplets emitted from a nozzle as they pass through a high voltage electric field established therebetween. Objectionable ink mist, which is unavoidably formed and diffused in various directions after the ink droplets impinge upon a recording paper or a beam gutter, attached to the grooved deflection electrode gathers and forms an ink drop, which is collected in an indent formed in the grooved deflection electrode. This precludes erroneous breaking down of the system and ensures stability of the high voltage electric field established between the pair of deflection electrodes.Type: GrantFiled: May 7, 1976Date of Patent: November 20, 1979Assignees: Nippon Telegraph and Telephone Public Corporation, Sharp Kabushiki KaishaInventors: Ichizo Nakano, Rikuo Takano, Tamaki Saito, Yuji Sumitomo, Toshio Kobayashi, Yoichi Yamamoto
