Abstract: This invention provides a heat-resistant voice coil of H class in heat-resistance standard, which is characterized in that an electrically insulated adhesive paint applied onto both a bobbin and conductor wire is mainly consisted of a mixture comprising all aromatic polyamide resin and a hardening agent composed of aromatic polyamic acid. This invention further provides a method of manufacturing such a heat-resistant voice coil, wherein the conductor wire coated with the paint is wound around the bobbin preliminarily coated with the paint in a semihardened state, while applying a non-water polar solvent onto the bobbin.

Abstract: A brake switch actuator for an autobicycle or the like is disclosed which includes a brake lever adapted to actuate a brake master cylinder mounted on a steering handle and also to actuate a brake switch so as to turn on and off a brake lamp at the tail of the body. The body of a brake master cylinder arranged frontwardly of a brake switch is disposed below the master cylinder with its longitudinal axis transverse to the longitudinal axis of the cylinder bore and also transverse to the longitudinal axis of the pivot, the brake lever having a downwardly extending arm which performs the dual function of operating the switch and also providing a stop which determines the retracted position of the brake lever.
