Title:
温度監視電子装置およびその実装による温度監視方法
Document Type and Number:
Japanese Patent JP4234951
Kind Code:
B2
Abstract:
An electrical charge is stored on a floating grid (8) which is separated from the other plate (10) of the capacitor by an insulating layer (12). A temperature operated contact (2) which may be bimetallic or alternatively a capsule containing a mixture of water and alcohol closes when a reference temperature is exceeded allowing the stored charge to leak to a charge flow circuit (18). The loss of charge is measured by a conduction change in a semiconductor (6) An Independent claim is also included for a method of monitoring temperature by implanting a stored charge and then detecting any subsequent absence of charge
