Publication number: 20160251996Abstract: A catalyst deterioration diagnosis apparatus includes an upstream side air-fuel ratio detector, a downstream side air-fuel ratio detector, an air-fuel ratio variation integrator that integrates the output variations of the respective air-fuel ratio detectors when a diagnosis running condition is satisfied, and a determiner that determines catalyst deterioration when the output variation integrated value of the upstream side air-fuel ratio detector exceeds a predetermined integration ending threshold, and further when a ratio between the output variation integrated value of the two detectors exceeds a predetermined determination threshold. The air-fuel ratio variation integrator holds the integrated values when the diagnosis running condition becomes unsatisfied before the integrated value of the upstream side air-fuel ratio detector reaches the integration ending threshold.Type: ApplicationFiled: February 23, 2016Publication date: September 1, 2016Applicant: FUJI JUKOGYO KABUSHIKI KAISHAInventors: Hiroyuki KANO, Shinsuke KOIKE

Publication number: 20160093283Abstract: A noise controller includes a first control unit that outputs a control signal for outputting sound for reducing noise to a first speaker, a first characteristic circuit that generates a signal by performing convolution, using a transfer characteristic from the second speaker to a second sound collector, on a control signal output from the first control unit to a second speaker, a subtractor that subtracts the signal generated by the first characteristic circuit from an output signal of a second sound collector and outputs a resultant signal. The first control unit generates the control signal to be output to the first speaker while the output signal from the subtractor serves as a reference signal so that an output signal of the first sound collector is minimized, and outputs the control signal to the first speaker.Type: ApplicationFiled: September 11, 2015Publication date: March 31, 2016Inventor: HIROYUKI KANO

Patent number: 9247370Abstract: An audio signal high frequency component controlled in terms of directivity is reproduced, or an audio signal high frequency component compensated in terms of frequency characteristic or controlled in terms of directivity is reproduced, such that the reflected sound comes from a direction in which the high frequency component is intended to be localized. The sound pressure in a seat where a desired localization effect is not provided due to the arrangement of speakers is compensated such that the interaural amplitude level in the seat is equal to that of another seat. Thus, an equivalent level of localization effect is provided in a plurality of seats, especially for an audio signal high frequency component, without significantly increasing the number of the speakers.Type: GrantFiled: August 27, 2012Date of Patent: January 26, 2016Assignee: PANASONIC INTELLECTUAL PROPERTY MANAGEMENT CO., LTD.Inventors: Ko Mizuno, Hiroyuki Kano
