Full titles differ between systems:
Non-adjustable resistors formed as one or more layers or coatings; Non-adjustable resistors made from powdered conducting material or powdered semi-conducting material with or without insulating material > the resistive layer or coating being tapered
Non-adjustable resistors formed as one or more layers or coatings; Non-adjustable resistors made from powdered conducting material or powdered semi-conducting material with or without insulating material (consisting of loose powdered or granular material H01C8/00; resistors having potential barriers, e.g. field-effect resistors, H10D1/40 - H10D1/43, H10K10/10; semiconductor devices sensitive to electromagnetic or corpuscular radiation, e.g. photoresistors, H10F30/00; magnetic field controlled resistors H10N50/10; bulk negative resistance effect devices H10N80/00) > the resistive layer or coating being tapered
