Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
135 words
A super-compact electric thermal treatment device, comprising: a small-capacity compact battery; a heating element for performing electrothermal conversion electrically connected to the battery and having a conducting adhesive material thereon for adhering the device to a user thereof; a switching means for intermittently switching current flowing from said battery through said heating element; a pulse supplying means electrically connected to the battery for generating output pulses of a given width and for supplying said output pulses to said switching means to control the intermittent switching of the switching means; and an adjusting means for manually adjusting the pulse width of the output pulses generated by the pulse supplying means to vary the amount of current intermittently supplied from the battery to the heating element and thereby the amount of heat generated by said heating element.
Claim 2
Dependent Claim
135 words
A super-compact electric thermal treatment device, comprising: a small-capacity compact battery; a heating element for performing electrothermal conversion electrically connected to the battery and having a conducting adhesive material thereon for adhering the device to a user thereof; a switching means for intermittently switching current flowing from said battery through said heating element; a pulse supplying means electrically connected to the battery for generating output pulses of a given width and for supplying said output pulses to said switching means to control the intermittent switching of the switching means; and an adjusting means for manually adjusting the pulse width of the output pulses generated by the pulse supplying means to vary the amount of current intermittently supplied from the battery to the heating element and thereby the amount of heat generated by said heating element.
Claim 3
Dependent Claim
17 words
The super-compact electric thermal treatment device of claim 1, wherein said heating element includes a ceramic substrate.
Claim 4
Dependent Claim
39 words
The super-compact electric thermal treatment device of claim 2, wherein said adjusting means varies an on-state duty ratio of the pulses provided by said pulse supplying means by adjustment of a combination of a variable resistor and a capacitor.
