Title: Orthogonal converter for vibration capacity type potentiometer
Inventor: KIHARA TAIZO
IPC: G01R29/12
Filed: 1995-07-26
Abstract: PROBLEM TO BE SOLVED: To obtain an orthogonal converter of a vibration capacity type potentiometer which requires neither a bias magnet nor a multiplier (or a frequency divider). SOLUTION: An orthogonal converter 8 has a residual magnetic type vibration electrode 37. The residual magnetic type vibration electrode 37 vibrates at a vibration frequency (f) by a magnetic field varying cyclically at a frequency (f) as generated by an electromagnetic coil 22. In other words, the residual magnetic type vibration electrode 37 is made up of a conducting material and a residual magnetic material and the conducting material functions as one electrode of a capacitor so that the residual magnetic material works to generate an attracting force and a repulsive force with respect to the magnetic field. Thus, the frequency of an output signal of the orthogonal converter 8 equals the frequency (f) of the signal generated by the oscillator 56 thereby eliminating the need for a multiplier or a frequency device. This also requires no bias magnet.

Abstract: PURPOSE:To improve a pleasant quality in the case of a heat load within a car room being more than a predetermined value, by arranging so that an air conditioning wind may be blown in a 'spot ventilation' in concentration to a seat occupied by a screw member on the basis of the inspecting signal of a crew member inspecting means. CONSTITUTION:A crew member inspecting means detects whether each seat is occupied or not, and inputs it into a controlling means. Meanwhile, a heat load inspecting means detects a heat load by detecting the difference between an actual car room inside temperature and a target car room inside temperature, and inputs it into the controlling means. The controlling means, when the heat load is more than a predetermined value, controls a wind quantity rate variable means so that the blowing out quantity of an air conditioning wind to an occupied seat may be increased more than the blowing out quantity to an unoccupied seat, according to a crew member seating situation from the crew member inspecting means. Thus, a pleasant quality can be improved by blowing the wind in a 'spot ventilation' to the occupied seat.
