Filed: 1987-10-23
Abstract: PURPOSE:To diminish the capacity of an inverter unit, by heightening the output frequency of the inverter unit more than the output frequency of the inverter unit in case that the whole linear motor has a secondary conductor. CONSTITUTION:The primary side 2 of a linear induction motor is fitted on the truck of an electric car, and a secondary conductor 3 is set between the rails of a track, as a reaction plate.

Inventor: SASAKI TORU
IPC: H03H21/00
Filed: 1992-09-09
Abstract: PURPOSE:To facilitate a miniaturization and to easily perform voice zooming by outputting only a desired voice signal by combining a pair of microphones for collecting the both main/reference voice with a noise reduction circuit including an adaptive filter. CONSTITUTION:The reference voice signal from a second microphone 21 where the sensitivity in a desired voice incoming direction is low has few correlations with the desired voice signal from a first microphone 11. This device is composed of an adaptive type noise reduction system, and when the output power from a subtraction means 15 is minimized, the reference voice signal is removed from the voice signal from the first microphone 11 and the only desired voice signal is outputted. Therefore, the device has a directivity which is sharp for a desired voice direction. The reduction processing of reference voice is limited by adding a no-correlation signal having no correlations with both main/ reference voice signals to the reference voice signal of the microphone 21 in an addition circuit 25. Thus, the zoom function for voice can be obtained.
