Introduced: January 1995

Full Title

Full titles differ between systems:

IPC:

Apparatus or processes specially adapted for manufacturing resistors > adapted for trimming > by removing or adding resistive material > by mechanical means, e.g. sand-blasting, cutting or ultrasonic treatment

CPC:

Apparatus or processes specially adapted for manufacturing resistors (providing fillings for housings or enclosures H01C1/02; reducing insulation surrounding a resistor to powder H01C1/03; manufacture of thermally variable resistors H01C7/02, H01C7/04) > adapted for trimming > by removing or adding resistive material (H01C17/23, H01C17/232, H01C17/235 take precedence) > by mechanical means, e.g. sand-blasting, cutting or ultrasonic treatment
