Abstract
An electric circuit substrate apparatus having a micro-processor for a control of a device is comprised of a substrate, an electric circuit arranged on the substrate and including a rectifier, an electrolysis condenser, a detecting device for detecting the voltage of a current outputted from the electrolysis condenser and the micro-processor which is set to stop the control of the device upon receipt of a signal from the detecting device, and an enclosing device for immersing therein the substrate and the electric circuit, except for a portion of electrolysis condenser, in order that the immersed elements are interrupted from the ambient air.
Claims7
An electric circuit substrate apparatus having a micro-processor for a control of a device comprising:
- a substrate;
- an electric circuit arranged on the substrate and including the micro-processor, a rectifier, an electrolysis condenser, and a detecting means for detecting the voltage of a current outputted from the electrolysis condenser;
- the micro-processor is set to stop the control of the device upon receipt of a signal from the detecting means;
- and
- enclosing means for immersing therein the substrate and the electric circuit, except for a portion of the electrolysis condenser, in order that the immersed elements are interrupted from the ambient air;
- wherein the portion of the electrolysis condenser to be exposed to the ambient air is a head of the electrolysis condenser, and
- wherein the raw material of the head of the electrolysis condenser is aluminum.
An electric circuit substrate apparatus having a micro-processor for controlling a device, comprising:
- a substrate;
- an electric circuit arranged on the substrate including:
- a condenser for smoothing an input voltage waveform to said apparatus;
- a detector for detecting a voltage output by said condenser;
- and
- a sealant covering said electric circuit except for a portion of said condenser;
- said detector outputting a signal to said micro-processor for causing said micro-processor to disable operation of said device;
- wherein:
- said sealant prevents exposure of electric circuit from ambient air except for said portion of said condenser;
- and
- said portion of said condenser is made of a material which corrodes due to exposure to said ambient air.
