Title: Inductor for power source filter
Inventor: TAKAYAMA MASARU
IPC: H01F1/16
Filed: 1981-03-31
Abstract: PURPOSE:To achieve improvement of HF properties in an inductor for mains line filtering application and also increase of a saturating magnetic flux density by use of a ferro-alloy magnetic substance containing silicon by 5-10wt% as a magneic core. CONSTITUTION:A wire 12 is wound around a closed-magnetic loop magnetic core 11 consisting of a ferro-alloy magnetic substance containing silicon of 5-10wt%. This magnetic core 11 is produced in such a process that a mixture or alloy containing silicon of 5-10wt% is fused and the fusion is contacted with the surface of a cooled matter to obtain a thin alloy plate. A thin band of this ferro-alloy magnetic material is extremely thin, and also its high-frequency property is very good because its insulating layer is formed during manufacture. Further, its saturating magnetic flux density is very large, so a large attenuation can be secured even against noises of a large amplitude. However, if silicon is contained by 10-pulse wt%, a saturating magnetic flux density is decreased, and if it is 5wt% or less, production of a thin band is very hard and also an effective permiability can be hardly obtained.

Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To always realize an optimum time alignment function without errors by changing a sound velocity value used for calculation for setting delay time in accordance with a temperature situation and setting optimum delay time. SOLUTION: When sound velocity is changed by the temperature change, a control part 1 calculates delay time which is to be given to the sound signals of respective channels, which correspond to that time. The delay time of the respective channels is multiplied by the value of a sampling frequency in an A/D converter 21 in the delay time of the respective channels and delay time is converted into the number of delay samples as a value for controlling delay quantity in DSP 22. The number of the delay samples of the respective channels is set in DSP 22 and DSP 22 delays and outputs the signals of the respective channels in accordance with the number of the delay samples which are set on the sound signals of the respective channels.  Thus, the time alignment function becomes valid and a state where all speaker units are artificially in equal distances is realized in a driving seat, for example.
