Patent number: 7503426Abstract: A reflecting plate type silencer pipe including a reflecting plate is provided for reducing a dominant frequency noise passing through a pipeline. Sound waves propagated in the pipeline as a one-dimensional plane wave are divided into two, that is, sound waves advancing straight along the pipeline and sound waves caused to pass through a bypass route by the reflecting plate thereby being delayed in phase. Both of the sound waves are joined again so as to synchronously advance in the same direction and in parallel to each other with the sound waves being the same in amplitude and opposite in phase to each other, and wave interference is effected between the sound waves, whereby wave propagation energy of the sound wave of the frequency to be silenced passing through the pipeline is selectively dissipated.Type: GrantFiled: August 14, 2006Date of Patent: March 17, 2009Assignees: MK Seiko Co., Ltd., Viva Co., Ltd.Inventor: Akira Yaoita

Publication number: 20080139107Abstract: A main body casing of a ventilator is formed with an outer airflow opening and an inner airflow opening and a ventilating path for connecting these airflow openings is formed in the main body casing. The ventilator ventilates a room and prevents entry of noise from outside into the room through the ventilating path. The ventilating path is bifurcated and these two ventilating paths have different lengths from each other so that a noise sound wave entering through one of the ventilating paths and a noise sound wave entering through the other ventilating path are out of phase with each other to cancel out each other's sound wave energy when the sound waves meet.Type: ApplicationFiled: September 21, 2007Publication date: June 12, 2008Applicant: MK SEIKO CO., LTDInventors: Shoichi Takeda, Yukito Obinata, Tsuyoshi Arai, Yuuki Nakamura

Publication number: 20080017441Abstract: A sound-deadening louver is attached to vents that are formed in a wall structure. The louver is composed of a plurality of blades that are inclined at an angle to the surface of the wall structure. Each blade has a sound-deadening chamber therein, and an opening is formed on that side which faces each vent in the wall structure. First reflecting plates and second reflecting plates are mounted in the blade so as to extend from an edge portion of the opening into the sound-deadening chamber. The first reflecting plates have a curved shape, while the second reflecting plates have a flat shape.Type: ApplicationFiled: June 12, 2007Publication date: January 24, 2008Applicant: MK SEIKO CO., LTD.Inventors: Shoichi Takeda, Yukito Obinata, Tsuyoshi Arai
