Patent number: 9462362Abstract: A microphone support device includes a ring-shaped flame, a plurality of fixed arms which protrude toward an inner side of the flame, a plurality of movable arms which are longer than the fixed arms and are detachable, and multiple microphones. A small-size microphone array is constructed by accommodating the plurality of movable arms inside of the flame in a radiating state. On the other hand, a large-size microphone array is constructed by radially developing the plurality of movable arms outside of the flame. When constructing a circular two-dimensional microphone array, a size of the circular two-dimensional microphone array can be easily changed in this manner. Hence, the sound localization can be handled over a wide frequency range.Type: GrantFiled: January 31, 2014Date of Patent: October 4, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Takaaki Yamanaka, Masaya Gotou, Toshihiko Kato

Patent number: 7379553Abstract: It is possible to simultaneously identify the sound coming direction from a sound source in all directions and estimate the sound intensity of the sound source. A plurality of microphones (11) are arranged on the surface of a baffle (10) of a shape such as a sphere and polyhedron so that sound from all directions are acquired. A calculation device (40) calculates the amplitude characteristic and the phase characteristic of acoustic signals acquired by the microphones (11). The signal information and information on sound field analysis around the baffle are integrated and calculation to emphasize a sound coming from a particular direction is performed for all the directions so as to identify the sound coming direction from a sound source. According to these calculation results and the distance input by an input device (70), it is possible to estimate the sound intensity of the sound source at a plurality of portions generated at the sound source or boundary surface.Type: GrantFiled: August 27, 2003Date of Patent: May 27, 2008Assignee: Nittobo Acoustic Engineering Co.

Patent number: 5168314Abstract: A cleaning apparatus for a fixing device wherein a movable cleaning web is brought into contact with a member of the fixing device to thereby clean the fixing member. The amount or time of rotation of a take-up shaft for taking up the cleaning web is reduced stepwise depending on the number of sheets of recording paper having been subjected to image recording. The amount or time of rotation of the take-up shaft is effected by using the relationship between the increase in the diameter of the take-up roller and the number of copies made stored previously.Type: GrantFiled: April 11, 1990Date of Patent: December 1, 1992Assignee: Konica CorporationInventors: Kouichi Gunji, Tsutomu Suka, Takaaki Yamanaka, Shogo Kato
