Filed: 2004-05-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a damper for a loudspeaker device capable of inhibiting large vibrations more than required in a voice coil bobbin or the like, in the case of an abnormal large-signal input or the like, and provide a loudspeaker device using the damper.  <P>SOLUTION: The damper with an annular elastic section is manufactured by annularly punching a metal-gauze raw material formed by reticulately knitting a plurality of metallic wires by a press device.

Consequently, the large vibrations (amplitudes) more than required of the voice coil bobbin, a diaphragm or the like can be inhibited/prevented even when the abnormal large-signal input is conducted to the loudspeaker device by adapting the damper to the loudspeaker device. Since the elastic section is formed in a reticulate shape and each metallic wire is not fixed mutually, each metallic wire can be displaced in response to the magnitudes of the vibrations of the diaphragm or the like when the loudspeaker device is driven.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To surely prevent deterioration of emissions by appropriately suppressing abnormal air fuel ratios caused by a downstream sensor, in sensors detecting air fuel ratios in an upstream and an downstream exhaust emission control catalyst.  <P>SOLUTION: It is detected based on a value of frequency of appearance Lr that output voltage of an O2 sensor existing in a downstream of a catalyst converter slips to a lean side, a control width B is established according to the frequency of appearance Lr (S208) and a plus side guard value dVgrd(+) is established with adding to a learning value DVG of correction amount (S210, S218). Degree of the abnormal condition of the O2 sensor can be reflected on the correction amount by the control width B, and variation of characteristics of an air fuel ratio sensor in the upstream side can be reflected to the plus side guard value sVgrd(+) since the learning value DVG is referred. Consequently, the correction value can be limited in an appropriate range where the degree of abnormal condition of the O2 sensor and variation of characteristics of the air fuel ratio sensor can be absorbed.
