Publication number: 20100258244Abstract: A lateral pipe that intersects a main pipe is lined using a lateral pipe-lining material having a tubular resin-absorbing material impregnated with a curable resin and having a flange formed at one end thereof. The flange of the lateral pipe-lining material is disposed on an expandable flange-pressing implement, and an adhesive is applied onto the flange. Hot water is fed to the flange-pressing implement to expand and press the flange against the periphery of the lateral pipe opening of the main pipe. The hot water thus fed also heats and cures the adhesive on the flange to secure it to the periphery of the lateral pipe opening of the main pipe. The drainage performance of the main pipe can be improved because a gap does not form between the flange of the lateral pipe-lining material and the periphery of the lateral pipe opening of the main pipe, and neither underground water nor earth or sand flows into the main pipe.Type: ApplicationFiled: April 12, 2010Publication date: October 14, 2010Inventors: Takao Kamiyama, Koji Kaneta, Kenji Fujii, Fuminori Tanaka

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
